A good source of hydrogen peroxide available in the form of powder or granules usually white-colored is sodium percarbonate.
Its chemical formula is (2Na2CO3.3H2O2).
It is observed that the sodium percarbonate is made by an additional reaction between hydrogen peroxide and carbonates of sodium available in the crystalline powder, commonly used as a cleaning agent. The sodium percarbonate has various properties like it is water-soluble, hygroscopic, and colorless and largely used in the laundry and cleaning industry and hence accelerates the growth of sodium percarbonate market in the global market.
Owing to the presence of hydrogen peroxide in the formation, it has a wider scope in detergent and bleaching agent application.
Sodium carbonate peroxyhydrate is transformed into hydrogen peroxide and sodium carbonate in the presence of water.
The hydrogen peroxide oxidizes the critical cellular components of the target organism and thus kills them.
Sodium percarbonate is mainly used as a bleaching chemical in laundry detergents, laundry additives and machine dishwashing products.
The pure product (100 %) is also available for consumers as a laundry additive.
Sodium percarbonate may also be used in products for drain cleaning, multipurpose cleaning or for denture cleansing.
Hydrogen peroxide has good microbial properties, particularly at elevated temperatures.
The product itself has been used as a disinfectant in concentrations ranging from 1 to 50%.
It is a very reactive material and should not be mixed with other chemicals.
Solid products such as sodium percarbonate or sodium perborate release hydrogen peroxide when dissolved in water and are used in powder detergents.
The name “sodium percarbonate” (SPC) does not reflect the structure of this oxidizing agent, which is in fact a carbonate perhydrate: 2 Na2CO3 • 3 H2O2.
Although SPC is very storage-stable if dry, the solid material has a slight vapour pressure of hydrogen peroxide leading to exchange with water or to violent reactions with oxidizable substrates, even in the solid state.
Sodium percarbonate is a source of highly concentrated hydrogen peroxide in non-aqueous systems, even if the material is not fully soluble. The addition of small amounts of water or sonication can increase the rate of oxidation.
For example, sodium percarbonate allows the convenient preparation of peroxyacids from acid chlorides, and even from the acids themselves. Thus, SPC can be used in epoxidations and Baeyer-Villiger oxidations in the presence of an acylating agent
Sodium percarbonate is 100% active ingredient so it is a very powerful cleaner.
Sodium percarbonate is sodium carbonate (i.e. Arm and Hammer Super Washing Soda) reacted with hydrogen peroxide and it is a very effective cleaner for all types of brewing equipment.
It rinses easily. Sodium percarbonate uses active oxygen to penetrate carbon or protein soils and has a high kill rate on wide range of microorganisms making it an effective sanitiser as well as cleaner.
This is a fantastic product for use on all brewery equipment including beer lines, pots, fermenters, heat exchangers.
It will effectively remove beer stone and dried up yeast.
Sodium percarbonate gradually decomposes into non-toxic, environmentally safe, food grade elements.
It decomposes into oxygen, sodium carbonate and water.
In our opinion, percarbonate-based cleaners are the best choice for equipment cleaning.
These products combine sodium metasilicate with the percarbonate in a stable form which increases its effectivity and prevents the corrosion of metals like copper and aluminum that strong alkaline solutions can cause.

Sodium percarbonate appears as a colorless, crystalline solid. Denser than water. May combust in contact with organic materials. Contact may irritate skin, eyes and mucous membranes. May be toxic by ingestion. Used to make other chemicals.
Sodium percarbonate is a chemical substance with formula Na2H3CO6.
Sodium percarbonate is an adduct of sodium carbonate (“soda ash” or “washing soda”) and hydrogen peroxide (that is, a perhydrate) whose formula is more properly written as 2 Na2CO3·3 H2O2.
Sodium percarbonate is a colorless, crystalline, hygroscopic and water-soluble solid. Sodium percarbonate is sometimes abbreviated as SPC. Sodium percarbonate contains 32.5% by weight of hydrogen peroxide.
Sodium percarbonate is used in some eco-friendly bleaches and other cleaning products.
Sodium percarbonate was first prepared in 1899 by Russian chemist Sebastian Moiseevich Tanatar
Structure
At room temperature, solid sodium percarbonate has the orthorhombic crystal structure, with the Cmca crystallographic space group.
The structure changes to Pbca as the crystals are cooled below about −30 °C
Chemistry
Dissolved in water, sodium percarbonate yields a mixture of hydrogen peroxide (which eventually decomposes to water and oxygen), sodium cations Na+, and carbonate CO2−3.
Production
Sodium percarbonate is produced industrially by crystallization of a solution of sodium carbonate and hydrogen peroxide, with proper control of the pH and concentrations.
This is also a convenient laboratory method.
Alternatively, dry sodium carbonate may be treated directly with concentrated hydrogen peroxide solution.
It may also be formed from a process starting from sodium peroxide When absolute ethyl alcohol reacts with sodium peroxide at 0° C. a perhydroxide is produced.
C2H5OH + Na2O2 – O:NaOH + C2H5ONa.
Carbon dioxide converts it into sodium hydrogen percarbonate.
World production capacity of this compound was estimated at several hundred thousand tons for 2004.
Uses
As an oxidizing agent, sodium percarbonate is an ingredient in a number of home and laundry cleaning products, including non-chlorine bleach products such as Oxyper, OxiClean, Tide laundry detergent,[1] and Vanish.[4]
Many commercial products mix a percentage of sodium percarbonate with sodium carbonate. The average percentage of an “Oxy” product in the supermarket is 65% sodium percarbonate and 35% sodium carbonate.
The “ultra boosters” seen on infomercials may contain as much as 80% sodium percarbonate.
Sodium percarbonate is also used as a cleaning agent by many home brewers.
Sodium percarbonate can be used in organic synthesis as a convenient source of anhydrous H2O2, in particular in solvents that cannot dissolve the carbonate but can leach the H2O2 out of it.
A method for generating trifluoroperacetic acid in situ for use in Baeyer–Villiger oxidations from sodium percarbonate and trifluoroacetic anhydride has been reported; it provides a convenient and cheap approach to this reagent without the need to obtain highly concentrated hydrogen peroxide
Sodium percarbonate is a great killer of bacteria, fungi, viruses and mildew, therefore can be used as a very effective exterior Algae removal agent and moss killer.
Sodium percarbonate is also an effective indoors product and is used as a house deodoriser, floor cleaner and carpet spot cleaner.

Methods of Manufacturing
Crystallization Processes.
The production of sodium carbonate peroxohydrate is mainly carried out by crystallization from aqueous solution.
Sodium carbonate is reacted with hydrogen peroxide at 10-20 °C, and crystallized in the presence of stabilizers, such as magnesium silicate, and salting-out agents, preferably sodium chloride.
Crystallization aids such as polyphosphates or polyacrylates are used.
The product is obtained as coarse, mechanically stable crystals, which are centrifuged followed by drying, preferably in a fluidized-bed dryer with an air inlet temperature of 75-130 °C.
The mother liquor from the centrifuge can be further concentrated and mixed with industrial-grade sodium carbonate (sometimes after adding a magnesium salt), filtered to remove iron compounds, and fed back into the crystallizer.
Processes that do not include a salting-out process with sodium chloride are usually less economic because of the lower space-time yield.
Spraying Processes. … These processes avoid the need for filtration and centrifugation of the crystalline product.
An aqueous solution or suspension of sodium carbonate and hydrogen peroxide is completely evaporated in a spray dryer.
The product has a very low bulk density (0.35 kg/L).
In a variation of this process, solutions of Na2CO3, and H2O2 are continuously sprayed onto a bed of sodium carbonate peroxohydrate fluidized with hot air.
The spraying and drying stages can alternatively be carried out in two stages.
In a further process variation, solutions of sodium carbonate and hydrogen peroxide are sprayed through separate nozzles into a reaction chamber into which a hot mixture of air and carbon dioxide is passed at the same time.
This process produces a rather porous sodium carbonate peroxohydrate.
A highly attrition resistant product with an active oxygen content of >14% and high bulk density (>1000 g/L) can be obtained in a continuous spray- granular process using a fluidized-bed reactor.
Dry Methods. In these processes, anhydrous or hydrated sodium carbonate (75-90 wt% Na2CO3) is reacted with a concentrated solution (50-80 wt%) of hydrogen peroxide, so that only a small amount of water must be removed.
This can be achieved in a mixer or fluidized-bed reactor in which gaseous hydrogen peroxide can be used.
Apart from the long reaction time, these dry processes have the disadvantage that no purification of the sodium carbonate takes place and therefore these sodium carbonate peroxohydrate products have only moderate storage properties.
However, this problem can be solved by recrystallizing the sodium carbonate before use and by using sodium carbonate monohydrate.
Sodium percarbonate is produced by the reaction of sodium carbonate with hydrogen peroxide, which can be done via dry, spray granulation and crystallization processes.
In the dry process aqueous hydrogen peroxide solution is sprayed on solid sodium carbonate; a solid-liquid reaction yields sodium percarbonate.
In the spray granulation process sodium percarbonate is produced by a fluid bed process.
Solutions of sodium carbonate and hydrogen peroxide are sprayed simultaneously into a drying chamber onto seed crystals whereby the water is evaporated.
In the crystallization process sodium percarbonate is usually formed by reacting solutions of sodium carbonate and hydrogen peroxide in a crystallizer possibly in combination with salting out agents.
Sanitizer for aquaculture water treatment is an option for organic aquaculture operation
Example of manual application of the hydrogen peroxide-containing powder product SPC.
Water treatment options for organic aquaculture are restricted, compared to those available to conventional fish farming; only easily degradable disinfectants are allowed.
One of the permissible water disinfectants that can be used in both conventional and organic aquaculture production systems is sodium percarbonate (SPC).
SPC is a dry, granulated form of hydrogen peroxide (H202), being a crystalline adduct of H2O2 with sodium carbonate (2Na2CO3·3H2O2; Fig. 1).
SPC decomposes in water into Na+, CO32- and H2O2. It has different trade names – Oxyper, Biocare or Oxypro – and is also referred to as “emergency oxygen powder.”
The product has documented anti-parasitic effects (Heinecke and Buchmann, Aquaculture 288.1 (2009): 32-35), controls unwanted algae growth and has sanitizing properties, and liberates oxygen during its decomposition.
The advantage of applying SPC over other H2O2 products is that it is safe and easy to handle.
Being a granulated powder, it can be evenly distributed in a pond or raceway by use of a hand shovel, as shown in the picture above.
The added powder can be visually checked as it precipitates to the bottom of the tank or raceway when added to the water, helping guide and ensure a safer, more even and effective distribution. Immediately after the addition of SPC to the water, hydrogen peroxide reacts with organic matter and bacteria in the sediment.
During the enzymatic breakdown of H2O2, oxygen is formed, which is seen as microbubbles emerging from the bottom/sediment. This process may help in liberating organic matter and debris from the bottom, which is another apparent, beneficial property of this product. The water quality is momentarily deteriorated as a result of this, and some decomposition products (flocculated material, particulate organic matter) may accumulate on the surface following the water treatment procedure.
Example of SPC application on a commercial fish farm
SPC can be used to improve water quality by the indirect addition of oxygen and associated elimination of bacteria.
As a side effect, it purifies the bottom in concrete raceways in hatcheries, and cleans up the sediment in earthen ponds when SPC reacts with the organic matter.
The dosages vary from system to system and depend on factors like fish size, water temperature and water quality (organic matter content).
In January 2017, we measured the associated effect of adding SPC to a 100 m3 earthen pond with juvenile (150 to 200-gram) rainbow trout.
An amount of 12 kg SPC was evenly added using a hand shovel to the pond over a period under five minutes.
At the outlet of the pond, oxygen and pH sensors were installed to record and log data prior to, and during SPC application. Water samples were collected in transects across the pond and from the outlet of the pond to assess hydrogen peroxide concentrations.
H2O2 concentrations were estimated by use of commercial Peroxid sticks (0-25 ppm H2O2) and analyzed in the field with a portable spectrophotometer and a fixating color reagent.
Perborate as a bleach component in heavy-duty laundry detergents is being increasingly substituted by percarbonate.
In the wash process, sodium percarbonate does form hydrogen peroxide and sodium carbonate.
Sodium carbonate is a water-soluble mineral and ubiquitously present in the aqueous environment as there is an equilibrium with carbon dioxide from the atmosphere and with other dissolved minerai carbonates.
While Na-percarbonate expectedly displays some aquatic toxicity due to the formation of unstable hydrogen peroxide (fish-LC50 = 71 mg/l, daphnia-EC50 = 4.9 mg/l), sodium carbonate has a very low aquatic toxicity (see Section 3.2.6).
Thus, the use of sodium percarbonate as detergent bleaching active will not have any significant impact on the aquatic organisms.
Hydrogen peroxide has good microbial properties, particularly at elevated temperatures.
The product itself has been used as a disinfectant in concentrations ranging from 1 to 50%.
It is a very reactive material and should not be mixed with other chemicals.
Solid products such as sodium percarbonate or sodium perborate release hydrogen peroxide when dissolved in water and are used in powder detergents.
Sodium percarbonate – Sodium percarbonate (Na2CO3·1.5 H2O2) is not a persalt but a perhydrate and so, is less storage stable than perborate.
As a carbonate source, it also contributes alkalinity to the wash liquor as it dissolves.
To enhance its stability, percarbonate is frequently marketed as granules coated with a protective disilicate-based layer.
The main user of sodium percarbonate is the household cleaning products industry, which is expected to use more than 95 % of the European sodium percarbonate demand.
Sodium percarbonate is mainly used as a bleaching chemical in laundry detergents (tablets,compact or regular powders), laundry additives and machine dishwashing products.
The concentrations of sodium percarbonate in the different household cleaning products are presented in Table 2.
However, higher concentrations are used also.
Bleach booster products with a sodium percarbonate concentration between 65 and 85 % are placed on the market.
Furthermore the pure product (100 %) is available for consumers as a laundry additive.
Minor amounts of sodium percarbonate may be used in products for drain cleaning, multipurpose cleaning or for denture cleansing.

Mainly as a result of environmental pressures to reduce borate content of detergents, sodium perborate has slowly been replaced by sodium carbonate peroxyhydrate, more commonly known as sodium percarbonate.
Sodium percarbonate exists as a colourless crystalline solid (2Na2CO3·3H2O2) and the peroxide is present as a perhydrate, hydrogen peroxide (H2O2) being incorporated in the crystal lattice rather than as a cyclic peroxide.
Due to the lack of stabilisation in a covalent, favourable, six-membered ring structure, sodium percarbonate is far less stable than sodium perborate, and must therefore be coated to provide sufficiently stable detergent formulations.
However, since percarbonate has a greater rate of dissolution, has a more environment-friendly profile and has the advantage of concurrently generating hydrogen peroxide and of liberating carbonate, which gives a higher pH than borate and favours perhydrolysis, percarbonate today is the form of hydrogen peroxide of choice in most European detergents.
Sodium percarbonate rapidly dissolves in water and dissociates into sodium, carbonate and hydrogen peroxide.
Acute ecotoxicity tests with fish and water fleas revealed LC50 values of 71 and 4.9 mg/l.
The available data show that the observed aquatic toxicity of sodium percarbonate can be explained by the formation of hydrogen peroxide.
Because sodium percarbonate dissociates into sodium, carbonate and hydrogen peroxide, the environmental risk assessment is based on the risk assessment of the individual components.
Sodium percarbonate is produced by the reaction of sodium carbonate with hydrogen peroxide, which can be done via dry, spray and wet processes.
In the dry process aqueous hydrogen peroxide solution is sprayed on solid sodium carbonate; a solid-liquid reaction yields sodium percarbonate.
In the spray process sodium percarbonate is produced by a fluid bed process.
Solutions of sodium carbonate and hydrogen peroxide are sprayed into a drying chamber where the water is evaporated.
In the wet process sodium percarbonate is usually prepared by cristallisation possibly in combination with salting out.
Sodium percarbonate, also known as Sodium Carbonate Peroxyhydrate, or oxygen bleach powder is a free-flowing, white powder.
It is an addition compound of sodium carbonate and hydrogen peroxide. Percarbonate has an active available oxygen content (13%) which is equivalent to 27.5% Hydrogen peroxide.
It breaks down to oxygen, water and sodium carbonate upon decomposition.
It is an environmentally safe bleaching agent.
Sodium Percarbonate / oxygen bleach offers many of the same functional benefits as liquid hydrogen peroxide.
It dissolves into water rapidly to release oxygen and provides powerful cleaning, bleaching, stain removal and deodorizing capabilities in addition to being effective at killing bacteria, fungus, viruses and algae. It has the added advantage of having no odour.
Uses for Sodium Percarbonate / Oxygen Bleach
Sodium percarbonate improves the performance of conventional detergents and shampoos on stubborn stains.
It is a gentle stain remover for synthetic carpeting and upholstery fabrics.
It saves time by allowing cleaning in one pass that would perhaps have taken two or three passes with a carpet cleaner that uses shampoo only.
It improves personal safety by eliminating the need to use harsher cleaning or stain removal products.
It also eliminates the need for expensive prespotters and stain removers. It prolongs carpet cleaner machine life by reducing the use of harsh and corrosive products.
It is very effective as a laundry presoak for heavily stained articles. It is colour safe. It brightens colours and prevents fabric from become yellowed or darkened.
On wood it is effective in removing mildew stains and weathering. The sodium carbonate acts as a built-in detergent, removing dirt and other deposits.
Thus, sodium percarbonate-based cleaners are effective in removing dirt, mildew and weathered grey residues.
Once treated the wood returns to its natural original appearance.
Oxygen bleach is excellent for cleaning and removing organic stains (such as coffee, tea, wine, fruit juices, foods, sauces, grass, pet stains and blood) from fabrics, plastics, fiberglass, porcelain, ceramics, wood, carpets, asphalt, concrete, etc. Oxygen bleach containing products can be used in any place in or around the house that need to be destained and deodorized; they are efficient, safe and economical.

Water Treatment using Sodium Percarbonate:
Sodium percarbonate is a quick oxygen-releasing agent, it can release a large of oxygen into water and increase the oxygen concentration of water for a long period of time. At the same time, it can improve the water quality and degrade the organic matter of water to reduce the toxicity of ammonia, nitrogen, H2S and algae. Applications for sodium percarbonate include treatment of biological upsets in ponds, treatment of sludges, municipal sewage treatment, dechlorination and water softening. In sewage treatment SPC helps to reduce the chemical oxygen demand and improve biodegradability. It neutralises pollutants such as sulphides, nitrosamines, amides, chlorine and thiosulphate. NB. Not for use in drinking water.
Uses of Sodium Percarbonate in the Textile Industry:
Sodium Percarbonate is used as a method of adding hydrogen peroxide to dye oxidation baths in order to fix the dye onto the fabric. SPC is used as the bleaching agent to improve fabric whiteness.when a solid bleach is desirable. It also offers a system for the fixation of sulphur dyes on fabrics. Sodium Percarbonate is not suitable for use with silk or wool.
Sodium Percarbonate in the laboratory:
Sodium percarbonate is a source of highly concentrated hydrogen peroxide in non aqueous systems. It is useful for solvents that cannot dissolve the carbonate but leech out the hydrogen peroxide from it. It behaves as an electrophile, because the driving force is the formation of carbonate. At room temperature solid SPC has the orthorhombic crystal structure.
sodium percarbonate allows the convenient preparation of peroxyacids from acid chlorides, and even from the acids themselves. Thus, Sodium percarbonate can be used in epoxidations and Baeyer-Villiger oxidations in the presence of an acylating agent.
Sodium percarbonate in trifluoroacetic acid is an effective reagent for the Baeyer-Villiger oxidation of ketones to esters.
The oxidation of primary and secondary alcohols by sodium percarbonate in the presence of catalytic amounts of both molybdenyl acetylacetonate and Adogen 464 gave fair to high yields of the corresponding carbonyl compounds.
Sodium percarbonate is an ideal and efficient oxygen source for the oxidation of tertiary nitrogen compounds to N-oxides in excellent yields in the presence of various rhenium-based catalysts under mild reaction conditions.

Reactivity Profile
Oxidizing agents, such as SODIUM PERCARBONATE, can react with reducing agents to generate heat and products that may be gaseous (causing pressurization of closed containers). The products may themselves be capable of further reactions (such as combustion in the air). The chemical reduction of materials in this group can be rapid or even explosive, but often requires initiation (heat, spark, catalyst, addition of a solvent). Explosive mixtures of inorganic oxidizing agents with reducing agents often persist unchanged for long periods if initiation is prevented. Such systems are typically mixtures of solids, but may involve any combination of physical states. Some inorganic oxidizing agents are salts of metals that are soluble in water; dissolution dilutes but does not nullify the oxidizing power of such materials. Organic compounds, in general, have some reducing power and can in principle react with compounds in this class. Actual reactivity varies greatly with the identity of the organic compound. Inorganic oxidizing agents can react violently with active metals, cyanides, esters, and thiocyanates.

The effects of sodium percarbonate and perborate usage on pulping and flotation deinking instead of hydrogen peroxide
Pesman, E., Imamoglu, S., Kalyoncu, E. E., and Kirci, H. (2014). “The effects of sodium percarbonate and perborate usage on pulping and flotation deinking instead of hydrogen peroxide,” BioRes. 9(1), 523-536.
_________________________________________
Abstract
The main objective of this study was to evaluate the potential of sodium percarbonate and sodium perborate utilization during repulping of old news and magazine paper mixture.
A series of experiments were performed to determine the effects of bleaching agents on ISO brightness and ink removal efficiency of pulp after flotation deinking.
Conventionally, with other parameters are constant, the ISO brightness of pulp was increased from 45.24% to 54.10% and ink elimination ratio at 950 nm of pulp was increased to 69.12% with 1% sodium hydroxide and 1% (as active oxygen content) hydrogen peroxide usage.
However, when sodium percarbonate was utilized instead of hydrogen peroxide (as 1% active oxygen content) without alkaline addition, the ISO brightness of the pulp was increased to 55.00%.
Also, unlike the other bleaching agents, a favorable effect of sodium percarbonate on ink detachment was observed.
The ink elimination ratio of floated pulp was increased to 74.31% with 1% (active oxygen) sodium percarbonate addition without alkaline usage.
There were no additive effects of sodium perborate usage on brightness, and ERIC value of pulp could be determined.
In this respect, sodium percarbonate utilization without sodium hydroxide addition was proposed for effective repulping, deinking, and prebleaching of waste papers, in a similar manner to the use of hydrogen peroxide.
Sodium percarbonate and sodium perborate are alkaline reactants unlike hydrogen peroxide and do not need extra caustic soda (NaOH) for bleaching activity.
Meshcherova and coworkers (1982) conducted laboratory studies on the use of sodium and potassium perborates for bleaching softwood kraft pulps and they concluded that it is more advantageous to bleach kraft pulp with potassium perborate than hydrogen peroxide.
Also sodium perborate monohydrate was utilized for reinforcement of oxygen delignification; it was found that the delignification ratio can be increased from 45.56% to 57.59% without selectivity loss (Pesman et al. 2010).
Varennes and coworkers (1996) used sodium perborate tetrahydrate for bleaching of thermomechanical pulp.
Brightness as high as 75% ISO was reached with the addition of 6.5% sodium perborate tetrahydrate.
CONCLUSIONS
This paper has focused on the use of sodium percarbonate and sodium perborate for prebleaching of waste papers during repulping.
These agents were examined with respect to ISO brightness, CIE L*a*b* values, yield parameters, and ink elimination ratios.
The advantage of using sodium percarbonate and sodium borate is that sodium hydroxide is not required for the bleaching reaction, since these chemicals contribute to alkalinity.
Sodium percarbonate is a solid form of hydrogen peroxide and sodium carbonate.
Likewise, sodium perborate is a solid form of hydrogen peroxide and sodium metaborate.
A solid form of these peroxide derivatives is another advantage in the terms of handling and storage.
Hydrogen peroxide requires special engineered safety precautions, but granulated percarbonate and perborate can be easily storage and used for bleaching processes.
Sodium percarbonate usage during pulping is more effective than sodium perborate on ISO brightness of pulp.
Sodium percarbonate can be activated at low temperatures (30 to 50 °C), and a reaction temperature of 45 °C can be used during pulping.
By contrast, perborate needs high temperatures (70 to 80 °C) for effective bleaching activity.
In a deinking process, an alkaline additive is necessary not only for bleaching of pulp but also necessary for ink removal from pulp.
Sodium percarbonate can provide the needed alkaline for deinking activity by itself.
Sodium percarbonate usage (1% active oxygen) was increased the ink elimination to 74.31% without sodium hydroxide addition.
It is concluded that sodium percarbonate application during repulping may provide advantages relative to sodium perborate and hydrogen peroxide for improving brightness and ink removal efficiency.

In terms of supply, the market has shown fluctuations during the past half-decade. However, demand for sodium percarbonate has been gradually increasing during the same period. This rift has led to increasing prices of raw materials as well as sodium percarbonate in recent times.
Overall, the sodium percarbonate market is expected to show moderate growth in terms of value during the forecast period, while growth in volume is expected to be low. Investments by companies to increase penetration, increasing demand for cleaning products and disinfectants, are expected to drive the expansion of the sodium percarbonate market size over the coming years.
Sodium Percarbonate Market Drivers
Use of sodium percarbonate for laundry has been constant, and is expected to increase during the forecast period. Demand for bleaching agents in textile and laundry industries is expected to gain significant traction during the forecast period. Growing need for wastewater treatment is expected to boost demand for sodium percarbonate. Scarcity of clean water is expected to further increase over the coming years. As sodium percarbonate is permissible for usage in conventional and organic aquaculture, demand in fish farming is expected to be moderate over the coming years.
Demand for the uncoated type accounts for a higher share in the sodium percarbonate market, but need for long-term storage in multiple end-use industries has been driving demand for coated sodium percarbonate. Demand for coated sodium percarbonate is expected to see significant traction from textile and laundry industries during the forecast period.

Sodium percarbonate has natural cleaning properties that make it easier to break down dirt and stains.
Sodium percarbonate is an essential chemical for cleaning supplies manufacturers.
Examples of common products made with sodium percarbonate include:
Laundry detergent
Dishwasher detergent

Household cleaner
Solid heavy duty laundry detergents count among the most efficient washing materials.
They contain, among other important components, bleaching agents and bleach activating compounds for the effective removal of stains and to improve the degree of whiteness.
In the past few decades sodium perborate has been used as the bleaching agent.
Because the bleaching effect is only active above 60°C, so-called bleaching activators have been developed to allow effecting bleaching at lower temperatures.
The demand for energy saving, as well as the availability of modern washing agents, has led to the fact that e.g. in Germany almost 70% of all washings today are carried out at temperatures below 40°C.
Based on its better efficiency and environmental considerations, sodium percarbonate has replaced sodium perborate in modern washing agents.
Recently, the European officials have required that sodium perborate be replaced by sodium percarbonate.
According to EU-DECREE No. 109/2012 dated 09 February 2012 various boron compounds, specifically perborates, may not be used in detergents after 20th June 2013.
The basis for this is, that a range of boron compounds have been shown to be harmfull to the reproduction organs, and that sodium percarbonate is available as a good and reliable alternative to sodium perborate.
The difference between these two bleaching agents, sodium percarbonate and sodium perborate, lies in the amount of freely available hydrogen peroxide.
Sodiumperborate releases only one molecule H2O2 and sodiumpercarbonate three of them
The sodium percarbonate market is expected to witness robust growth in the near future, thanks to rising demand for eco-friendly bleaches and deodorants, especially from emerging countries.

Sodium Percarbonate (Tips to use)
1. What is Sodium Percarbonate?
Sodium Percarbonate (or sodium carbonate peroxyhydrate) is an addition compound of sodium carbonate and hydrogen peroxide.
When dissolved into water, its releases H2O2and soda ash (sodium carbonate).
2Na2CO3 . 3H2O2 —> 2Na2CO3 + 3H2O2
The pH of the resulting solution is typically alkaline, which activates the H2O2 for bleaching.
The dry powder contains about 30% w/w H2O2.
2. What are the applications of Sodium Percarbonate?
Sodium percrabonate has a wide range of applications in various solid detergent products and all fabric bleaches.
We may also find its usages in oxygen release compositions, personal care formulations, disinfectants, food bleaches, pulp and paper bleaches and textile bleaches, etc.
3. What are the advantages of Sodium Percarbonate?
Compared with chlorine bleaching chemicals that have contaminations on the environment, Sodium Percarbonate is an environmentally friendly chemical which decomposes into oxygen, water and natural soda ash when in contact with hydrous media.
Sodium Percarbonate is increasingly being the substitute for sodium perborate in detergent formulations due to its lower dissolving temperature in water, as well as the characteristic of no contamination on soil, as sodium perborate is made of borax which is found to have negative impact on the soil quality.
Detergent or bleach compositions formulated with Sodium Percarbonate have an strong stain removal capability.
It is very effective as a laundry presoak for heavily stained articles. It is color safe.
It brightens colors and prevent fabric form become yellowed or darkened.
Sodium Percarbonate is effective as a disinfectant on both bacteria and virus.
It is an excellent ingredient in personal care and home care formulations for hygiene.
For its environmental advantages, Sodium Percarbonate is a good oxygen release chemical for agricultural and aquicultural applications.
What are the difference between the coated and uncoated Sodium Percarbonate?
Sodium Percarbonate is used as an active oxygen component in detergents, bleaches and cleaning agents.
Due to the unsatisfactory storage stability of the uncoated Sodium Percarbonate in warm/moist surroundings and in the presence of certain detergent and cleaning agent components, Sodium Percarbonate must be stabilized against the loss of active oxygen.
An essential principle of stabilization involves encasing the Sodium Percarbonate particles in a coating of components having a stabilizing action. Here comes the definetion: the coated Sodium Percarbonate is the Sodium Percarbonate crystals coated with single or multiple layers of various substances in order to increase active oxygen stability and optimize storage and ensiling properties.
Coated Sodium Percarbonate is the more commonly commercialized peroxide compared with the uncoated Sodium Percarbonate.
But the uncoated product is still the preferred ingredient for simply mixing with enough quantity of soda ash and some surfactants to form the popular oxygen bleaches.
