WHAT IS 12-HYDROXYSTEARIC ACID?
Standard-grade 12-HSA is a saturated fatty acid produced by hydrogenating castor oil, which is naturally derived from castor beans.
The oil’s double bonds are saturated as a result of hydrogenation, producing stearic acid.
Manufacturers perform the process at room temperature using pressure and an alcohol solvent.
You may recognize the ingredient by 12-Hydroxy Stearic Acids light color and high melting point.

Hydroxystearic Acid as a Surfactant
By itself, water is not the most effective cleaning agent.
While water loosens dirt and debris, 12-Hydroxy Stearic Acid is repelled by grease and oil — to help water clean effectively, another substance must be added to the water to lower its surface tension. This is why surfactants are essential in cleaning products.
Designed to reduce the surface tension of water, surfactants help water molecules interact with grease and oil.
Surfactants work by using opposing forces.
These cleansing molecules have a hydrophilic head and a hydrophobic tail, and both components are essential for a surfactant to work effectively — the hydrophilic head binds to water molecules, while the hydrophobic tail binds to dirt and oils.
The hydrophobic tail also repels water molecules, creating more space and reducing the overall surface tension of the liquid.
As a surfactant, hydroxystearic acid helps water mix with oils and dirt.
When used in cosmetic products, 12-HSA helps clean hair and skin of any grease or debris.
Once loosened, the various oils and dirt are easily rinsed away, resulting in a fresh, clean surface.

Optically active 12-D-hydroxystearic acid (12-HSA) gives a thermally reversible organogel in several organic solvents.
When a small amount of lecithin coexists with 12-HSA in organic solvents, the mechanical strength of the organogel is remarkably reduced.
Interaction of lecithin with 12-HSA was studied by using infrared (IR) spectrometry, nuclear magnetic resonance (NMR) spectrometry, and scanning electron microscopy (SEM).
Incorporating lecithin into 12-HSA reduced the absorbance in IR spectra, derived from hydrogen bonding between the hydroxyl groups and the carboxyl groups of 12-HSA molecules.
Based on NMR measurements, the polar head groups of lecithin associate with the carboxyl groups of 12-HSA in a 1:1 molar ratio.
SEM showed that the shape of the fibrous aggregates varied from a helically extended form to a spherical form.
These results suggest that intermolecular 1:1 complexes were formed between lecithin and 12-HSA, which caused a structural change in the fibrous network in the 12-HSA organogel and consequently induced gel deformation.

12-Hydroxystearic acid (12-HSA) appended new amphiphilic scaffolds reveal excellent hydrogelation propensity in the presence of aqueous acids and vapors of HCl/HBr.
This selective entrapment efficiency towards hydrogen halides demonstrates an unprecedented route for the successful removal of toxic chemicals, thus providing a safe and easy protocol for environment management.
We anticipate that the halide derivative of the amphiphile plays a vital role in driving the self-assembly mechanism and eventually the hydrogelation phenomena.

A comprehensive review of the features driving self-assembly of 12-hydroxystearic acid (12-HSA), a low-molecular-weight gelator, and its applications in drug delivery and as other soft innovative materials are presented herein.
12-HSA is obtained via hydrogenation of ricinoleic acid naturally found in high concentrations in castor oil.
The ability of 12-HSA to self-assemble is associated with the presence, position, and enantiomeric purity of the hydroxy group along the fatty acid chain.
The polarity and position of the hydroxyl group facilitates more interaction possibilities leading to 12-Hydroxy Stearic Acids exceptional self-assembly behavior giving rise to fibers, ribbons, and tubes in a variety of solvents.
Upon self-assembly, 12-HSA undergoes crystallization resulting in the formation of high aspect ratio fibrillar structures due to noncovalent, intermolecular interactions forming self-spanning, three-dimensional networks (called self-assembled fibrillar networks) in both aqueous and organic solvents.
Herein, emphasis is placed on emerging applications of 12-HSA supramolecular assemblies (i.e. responsive aqueous foams, gelled complex fluids, drug delivery systems, hydrogels, organogels, xerogels, and aerogel).
The vast literature is compiled associated with 12-HSA self-assembly exploring supramolecular assemblies based on one ambidextrous gelator capable of assembling in aqueous and nonaqueous solvent.

Overview of Hydroxystearic Acid
Also called 12-hydroxy stearic acid and 12-HSA, hydroxystearic acid is a fatty acid surfactant, emollient and thickener.
Hydroxystearic acid is used widely in a variety of personal care and cosmetics products, including skin care preparations, hair products and deodorizing products.
Structurally similar to stearic acid, hydroxystearic acid is entirely vegetable-based and derived from naturally-occurring fats and oils, most commonly castor oil.
12-HSA is synthesized by oxidizing 2-hexylcyclododecanone with a mixture of permaleic and peracetic acids in methylene chloride.
This forms the lactone of hydroxystearic acid, and alkaline hydrolysis of the lactone produces 12-HSA.

Castor oil is the source of numerous products and is the only commercial source of the fatty acid ricinoleate, 12-hydroxy-oleate.
Hydrogenated castor oil is similarly useful as the source of 12-hydroxy-stearic acid, best known as a component of lithium grease.
Mono- and diacylglycerols are derived from castor oil and are useful in development of lubricants and emulsifiers for cosmetics, pharmaceutical and food use.
Acylglycerols derived from hydrogenated castor oil may be similarly useful, albeit with different physical and chemical properties.
We have evaluated the use of immobilized lipases to generate acylglycerols, using organic solvents to modulate the action of lipase to produce mono- and diacylglycerols, using tri-(12-hydroxy stearoyl)-glycerol as a model for hydrogenated castor oil.
The presence of an alkylated oxygen in the solvent appears to be an important factor in supporting lipase activity, with diisopropyl ether providing the best yield of di-(12-hydroxy stearoyl)-glycerol.

Vegetable oils due to high biodegradability, low toxicity, renewability and excellent lubricating performance, have immense potential to replace mineral oils as feedstock for lubricants.
Owing to these aspects environmentalists and engineers have made attempts to explore the possibilities of using vegetable oils as environmentally friendly lubricants for range of applications.
In this work, the tribological properties of castor oil and sesame oil in the presence of 12-hydroxystearic acid as anti-wear additive were investigated using four-ball tribometer.
The viscosity, acid value, peroxide value and iodine value of the selected oils were determined experimentally following AOCS methods.
Results revealed that the addition of 12-hydroxystearic acid improved the anti-wear performance of the selected vegetable oils.
Moreover, it was noted from the results that 12-hydroxystearic acid was more effective as anti-wear additive in the castor oil as compared to sesame oil under similar experimental conditions.
The improved anti-wear performance of the selected vegetable oils in the presence of additive may be attributed to the formation of protective layer as a result of tribochemical reaction on the metal surface.
Some of the most popular applications for hydroxystearic acid include the following products:
-Lotions
-Creams
-Gels
-Make-up and decorative cosmetics
-Hair care, such as shampoos, conditioners and styling products
-Skin care, such as facial care and cleansing, body care and baby care products
-SPF enhancement
-Sun care, such as sun protection, self-tanning and after-tanning products
-Underarm deodorants
-In any given cosmetics product, hydroxystearic acid is used in three primary functions — as a surfactant, emollient and thickener.

poly-12-hydroxy stearic acid (PTHSA) was synthesized and then modified by esterification with pentaerythritol to obtain a polyol polymeric hyperdispersant (polyol-PTHSA).
Under suitable reaction conditions (molar ratio pentaerythritol/PTHSA, 1.2:1; reaction temperature, 453 K; and reaction time, 4−8 h), the polyol-PTHSA with acid value of 3 mg of KOH/g can be obtained.
The structures were confirmed by FT-IR analysis.
The polyol-PTHSA was subsequently used as a hyperdispersant in the process of preparing environmentally friendly overbased calcium oleate detergent to increase the total base number of the product.
Reaction conditions including the polymerization catalyst, the catalyst amount, the amount of xylene, the polymerization temperature, the polymerization time, the polyol-PTHSA amount, and the acid value of the PTHSA were optimized.
