Triacetin was first prepared in 1854 by the French chemist Marcellin Berthelot.

Uses
It is an artificial chemical compound, commonly used as a food additive, for instance as a solvent in flavourings, and for its humectant function, with E number E1518 and Australian approval code A1518.
It is used as an excipient in pharmaceutical products, where it is used as a humectant, a plasticizer, and as a solvent.

The plasticizing capabilities of triacetin have been utilized in the synthesis of a biodegradable phospholipid gel system for the dissemination of the cancer drug paclitaxel (PTX).
In the study, triacetin was combined with PTX, ethanol, a phospholipid and a medium chain triglyceride to form a gel-drug complex.
This complex was then injected directly into the cancer cells of glioma-bearing mice.
The gel slowly degraded and facilitated sustained release of PTX into the targeted glioma cells.

Additionally, preliminary research also suggests that triacetin can be used to directly treat glioblastoma.
The study found that triacetin is a viable mediator for acetate supplementation, a therapy that inhibits glioblastoma cell growth.

Triacetin can also be used as a fuel additive as an antiknock agent which can reduce engine knocking in gasoline, and to improve cold and viscosity properties of biodiesel.

It has been considered as a possible source of food energy in artificial food regeneration systems on long space missions.
It is believed to be safe to get over half of one’s dietary energy from triacetin.

Synthesis
Triacetin was prepared in the 19th century by boiling together glycerol and acetic acid, and distilling the product.
Its synthesis from acetic anhydride and glycerol is simple and inexpensive.

3 (CH3CO)2O + 2 C3H5(OH)3 → 2 C3H5(OCOCH3)3 + 3 H2O

This synthesis has been conducted with catalytic sodium hydroxide and microwave irradiation to give a 99% yield of triacetin.
It has also been conducted with a cobalt(II) Salen complex catalyst supported by silicon dioxide and heated to 50 °C for 55 minutes to give a 99% yield of triacetin.[1

The triglyceride 1,2,3-triacetoxypropane is more generally known as triacetin, glycerin triacetate or 1,2,3-triacetylglycerol.
It is the triester of glycerol and acetylating agents, such as acetic acid and acetic anhydride.
It is a colorless, viscous and odorless liquid at standard temperature and pressure (STP) with a high boiling point and a low melting point.
It has a mild, sweet taste in concentrations lower than 500 ppm, but may appear bitter at higher concentrations.
It is one of the glycerine acetate compounds.

Triacetin is a triglyceride obtained by acetylation of the three hydroxy groups of glycerol.
It has fungistatic properties (based on release of acetic acid) and has been used in the topical treatment of minor dermatophyte infections.
It has a role as a plant metabolite, a solvent, a fuel additive, an adjuvant, a food additive carrier, a food emulsifier, a food humectant and an antifungal drug.
It derives from an acetic acid.

Product description
Triacetin is a clear, colourless acetate ester used for example in the manufacture of cigarette filters.
Triacetin is also used for plasticising NBR and cellulose derivatives.

Storage stability: Under suitable conditions, Triacetin can be stored for one year.

Triacetin, also known as Glyceryl Triacetate, is reported to function as a cosmetic biocide, plasticizer, and solvent in cosmetic formulations, at concentrations ranging from 0.8% to 4.0%.
It is a commonly used carrier for flavors and fragrances.
Triacetin was affirmed as a generally recognized as safe (GRAS) human food ingredient by the Food and Drug Administration (FDA).
Triacetin was not toxic to animals in acute oral or dermal exposures, nor was it toxic in short-term inhalation or parenteral studies, and subchronic feeding and inhalation studies.
Triacetin was, at most, slightly irritating to guinea pig skin.
However, in one study, it caused erythema, slight edema, alopecia, and desquamation, and did cause some irritation in rabbit eyes.
Triacetin was not sensitizing in guinea pigs.
Triacetin was not an irritant or a sensitizer in a clinical maximization study, and only very mild reactions were seen in a Duhring-chamber test using a 50% dilution.
In humans, Triacetin reportedly has caused ocular irritation but no injury.
Triacetin was not mutagenic.
Although there were no available reproductive and developmental toxicity data, Triacetin was quickly metabolized to glycerol and acetic acid and these chemicals were not developmental toxins.
Reports of 1,2-glyceryl diesters, which may be present in Triacetin, affecting cell growth and proliferation raised the possibility of hyperplasia and/or tumor promotion.
The Cosmetic Ingredient Review (CIR) Expert Panel concluded, however, that the effects of 1,2-glyceryl diesters on cell growth and proliferation require longer ester chains on the glycerin backbone than are present when acetic acid is esterified with glycerin, as in Triacetin.
On the basis of the available information, the CIR Expert Panel concluded that Triacetin is safe as used in cosmetic formulations.

This report reviews the safety of Triacetin, an ingredient that is reported to function as a cosmetic biocide, plasticizer, and solvent in cosmetic formulations

Triacetin is derived by the action of acetic acid on glycerol, with vacuum distillation used as the method of purification (Lewis 1993b).
It can also be prepared by esterification of glycerin with acetic anhydride (Gennaro 1990), by the acetylation of glycerol, by the reaction of oxygen with a liquid-phase mixture of allyl acetate and acetic acid using bromide as a catalyst (Budavari 1989), and from glycerin and acetic anhydride

Impurities Triacetin contains trace moisture and acetic acid (Unichema Chemie B.V. 1994).
Food-grade Triacetin must be at least 98.5% C9H14O6, and it must not contain >5 mg/kg heavy metals (as Pb) or>0.2% water (NAS 1996).
USP-grade Triacetin must contain not less than 97.0% and not greater than 100.5% C9H14O6, calculated on the anhydrous basis (USP 1994).
USE Cosmetic Triacetin is reported to function as a cosmetic biocide, plasticizer, and solvent in cosmetic formulations (Pepe, Wenninger, and McEwen 2002).
It is a commonly used carrier for flavors and fragrances.

According to the Ministry of Health, Labor and Welfare (MHLW) in Japan, Triacetin is not restricted in any manner in cosmetic formulations (MHLW 2001).
Triacetin does not appear in Annex II (list of substances that must not form part of the composition of cosmetic products) or Annex III (list of substances that cosmetic products must not contain except subject to the restrictions and conditions laid down) of the Cosmetics Directive of the European Union (European Commission 2003)

Noncosmetic Triacetin is a generally recognized as safe (GRAS) ingredient (21 CFR 184.1901) by the FDA.
It is used in foods as a flavoring agent and adjuvant, formulation aid, humectant, and solvent and vehicle; it has no limitations other than good manufacturing practice.
In its determination that Triacetin was a GRAS ingredient (FDA 1983, 1989), FDA relied upon an evaluation on glycerin and glycerides prepared by the Federation of American Societies for Experimental Biology (FASEB) that included safety-test data on Triacetin.
This FASEB evaluation found that Triacetin was without toxic effects in long-term feeding studies in rats that used doses that were higher than those to which consumers would be exposed (FASEB 1975). In addition, FDA contracted with a laborartory to perform a mutagenic evaluation of Triacetin, the results of which demonstrated no mutagenic activity (Litton Bionetics, Inc. 1976).
Triacetin is used in pharmaceuticals as a hydrophilic plasticizer in polymeric coatings of capsules, tablets, beads, and granules, with typical concentrations of 10% to 35% w/w (Unichema International 1996).
Triacetin is used as an antifungal drug for treatment of superficial fungus infections of the skin (Gennaro 1990).
However, data are inadequate to establish general recognition of the safety or effectiveness of Triacetin as an over-thecounter topical antifungal drug (21 CFR 310.545).
Triacetin has been used with prostaglandin E2 (PGE2) to form a gel used for preinduction cervical softening (Graves et al. 1985; Noah et al. 1985).

According to Yalkowsky and Roseman (1979), Triacetin stabilized PGE.
Triacetin had wide use in foundry applications as a curing agent for phenol resins used in the manufacture of sand molds.
It is used as a cellulose acetate plasticizer in the manufacture of cigarette filters, a tobacco humidifier, a plasticizer for cellulose nitrate, and a solvent for basic dyes and in the manufacture of celluloid and photographic films, as well as in the paint, lacquer, and varnish industries.
Triacetin is also used in removal of carbon dioxide from natural gas (Lewis 1993b).
According to Budavari (1989), technical Triacetin (a mixture of mono-, di-, and small quantities of Triacetin) is used as a solvent for basic dyes, particularly induline dyes, and tannin in dyeing. GENERAL BIOLOGY Absorption, Distribution, Metabolism, Excretion In an in vitro study by Stoughton (1970), the penetration of Triacetin into the corium of human skin was determined by topical application of Triacetin to the epidermis (which was later separated from the corium), and then measuring the antimicrobial activity.
Using leg skin, a plastic cylinder was attached to the epidermis, and 0.01 cc Triacetin was applied for 20 to 24 h.
The skin was then washed and the epidermis removed. Six-millimeter punches of the corium were taken and implanted on the culture medium, with the epidermal side in contact with the medium. When inhibition of growth around the corium occurred, the radius of inhibition was measured.
There was no average inhibition of positive responses with Triacetin cream.
The researchers speculated that an antimicrobial agent may penetrate into the corium and not diffuse into the surrounding medium when assayed, and that this might give a false-negative report of its ability to penetrate the epidermis. von Oettingen (1960) stated that Triacetin is absorbed from the gastrointestinal tract, but no experimental details were provided.
Pharmacological Effects In a series of studies, the use of Triacetin in total parenteral nutrition was examined.
Six female mongrel dogs were used to determine the effect of Triacetin on serum phosphorus, calcium, and magnesium metabolism.
A 5% v/v aqueous solution of Triacetin was infused intravenously at a rate of 47 µmol/kg/min for 3 h.
Arterial blood was sampled at 15 to 30-min intervals, and urine was collected during infusion.
No significant changes in total serum calcium or phosphorus concentrations were observed; however, serum magnesium concentrations were statistically significantly decreased 90 min after the initiation of dosing and remained decreased until the end of the study.

During Triacetin infusion, the plasma acetate concentration increased from 0.13 to 1.32 mmol/L at 30 min; the concentration gradually declined to ∼1 mmol/L during the last hour of the study. No change was observed in the fractional excretion of calcium, magnesium, or phosphorus.

The authors speculated that the decrease in serum magnesium was probably because of cellular uptake rather than accelerated excretion.

Baseline blood pH was not significantly altered.
Bailey, Haymond, and Miles (1991) also used groups of female mongrel dogs to study the metabolic effects of isocaloric and hypercaloric infusions of 5% v/v aqueous Triacetin.
A primed, continuous infusion of ∼5 µmol/kg (0.3 µCi/kg/min) [ 13C]-acetoacetate and ∼1.0 µCi/kg (0.01 µCi/kg/min) [3H]- glucose was continued for 6 h.
Three hours after the start of the isotope infusion, dosing with Triacetin was started.
Six animals were infused at a rate of 47 µmol/kg/min and seven were infused at a rate of 70 µmol/kg/min Triacetin for 3 h.
Blood and breath samples were taken at 15 to 30-min intervals.
A group of four animals was infused with 70 µmol/kg/min glycerol and used as the control for the hypercaloric infusion.
During isocaloric infusion of Triacetin, plasma acetate and free fatty acid concentrations were significantly increased at 30 and 60 min, respectively, and remained elevated.
During hypercaloric infusion, plasma acetate concentration increased progressively throughout the study, whereas the plasma free fatty acid concentration did not change.
Plasma pyruvate and lactate concentrations were significantly decreased after 30 and 90 min, respectively, and throughout the study with both isocaloric and hypercaloric infusion.
The plasma insulin concentrations were modestly increased during both infusions.
Plasma glucose concentration was significantly decreased during isocaloric Triacetin infusion; a slight but significant increase was observed with hypercaloric infusion. Glucose clearance decreased significantly in both groups during the last hour of Triacetin infusion.
Plasma ketone body concentrations increased significantly by 60 min, and they remained elevated with isocaloric infusion and increased progressively with hypercaloric infusion of Triacetin; the increased concentrations were due to increased ketone body production.
During the last hour of infusion, resting energy expenditure was significantly increased with isocaloric Triacetin (Bailey, Haymond, and Miles 1991).
In a study examining the effect of Triacetin on nitrogen balance, whole-body kinetics, and muscle and liver fractional protein synthetic rates, Bailey, Barker, and Karlstad (1992) infused male Sprague-Dawley rats with isovolemic, isocaloric, and isonitrogenous parenteral diets.
Thirty percent of the nonprotein energy of the diets was lipid energy, and for groups of 6, 10, and 6 animals, the lipid energy was composed of 0%, 50%, and 90% Triacetin, respectively.
No difference was observed in the plasma acetate concentration of animals that received Triacetin compared to those that did not.
The liver weight was significantly decreased in the animals given Triacetin.
Protein concentration in the liver and rectus muscle was similar for all three groups.
Cumulative nitrogen balance was positive for all animals, and no significant difference in nitrogen balance was observed on days 6 and 7.
Lipid composition had very little effect on plasma leucine kinetics.
Also, fractional protein synthetic rates in the rectus muscle and liver were similar for all animals.

Further work by Bailey, Miles, and Haymond (1993) reported the effect of a 5% v/v aqueous solution of Triacetin on leucine metabolism using female mongrel dogs.
A primed, continuous infusion of L-[1-14C]-leucine was continued for 6 h.
Three hours after the start of the isotope infusion, administration of Triacetin was started.
Six animals were infused at a rate of 47 µmol/kg/min and seven were infused at a rate of 70 µmol/kg/min Triacetin for 3 h.
Blood and breath samples were taken at 15 to 30-min intervals.

A group of four animals was infused with 70 µmol/kg/min glycerol and a group of five animals was infused with saline; both were used as control groups.
During the last hour of dosing, plasma acetate concentrations increased from 0.13 to 0.99 and from 0.10 to 11.8 for the animals infused with 47 and 70 µmol/kg/min Triacetin, respectively. Plasma glucose concentration decreased slightly but significantly for the animals given 47 µmol/kg/min Triacetin.
Plasma leucine concentration decreased significantly in the animals given 70µmol/kg/min Triacetin.
Plasmaα-ketoisocaproate concentration and specific activity increased with both doses. 14CO2 excretion was increased with the low dose and decreased with the high dose of Triacetin.
The conclusion of this series of studies was that due to the water solubility, minimal effect on mineral metabolism, improved nitrogen balance, lack of toxicity, and favorable effects on protein metabolism, Triacetin warranted further study as a parenteral nutrient.

Bleiberg et al. (1993) used mongrel dogs to determine the systemic, hindlimb, gut, hepatic, and renal uptake of acetate during infusion of a 5% v/v aqueous solution of Triacetin.
A primed, continuous infusion of [1-14C]-acetate was continued for 7 h with 10 animals.
Three hours after the start of the tracer infusion, the animals were infused with Triacetin at a rate of 47 µmol/kg/min for 4 h.
Blood and breath samples were taken at 15-min intervals for the last 30 min.
Steady-state conditions were achieved in plasma acetate concentrations and specific activity and in expired 14CO2.
Plasma acetate concentrations were ≈1180, ≈935, ≈817, ≈752, and ≈473 µmol/L in the aorta, renal vein, portal vein, femoral vein, and hepatic vein, respectively.
The acetate turnover rate during Triacetin infusion was 2214 µmol/min; systemic acetate turnover accounted for 68% of Triacetin-derived acetate.
The researchers concluded that the majority of triacetin undergoes intravascular hydrolysis, and the majority of the resulting acetate is oxidized.
Lynch, Miles, and Bailey (1994) determined the metabolic effect of Triacetin on intestinal mucosa cells and plasma substrates in a 30-day feeding study in which male Sprague-Dawley rats were given a diet that contained Triacetin. Groups of eight animals were fed a diet in which 30% of the energy was supplied as lipids, and Triacetin composed either 0 or 95% of the lipids (long-chain triglyceride [LCT] or Triacetin group, respectively); the remainder of the lipid was a long-chain triglyceride. (In the Triacetin-containing feed, Triacetin composed 19% of the diet by weight.)
A control group of eight animals was fed chow that supplied 5% of the energy as LCTs.
Body weights and feed consumption were measured throughout the study.
At study termination, animals of the LCT group weighed more than the animals of the Triacetin or control groups.
Feed consumption was not statistically significantly different between the Triacetin and LCT groups; however, during week 2 for the Triacetin group and weeks 2 to 4 for the LCT group, feed consumption was significantly greater than that of controls. No significant differences in lactate, ketone body, or glucose concentration were observed among the groups. Plasma pyruvate concentration in the Triacetin group was significantly decreased compared to the LCT group, and plasma free fatty acids were significantly decreased and the plasma triglyceride concentration was significantly increased in the Triacetin group compared to animals of the control and LCT groups.
Total intestinal DNA, RNA, protein, and protein: DNA ratio were measured.
No significant difference in mucosal protein concentration was observed in the jejunum and colon.
Jejunal and colonic DNA content was significantly increased (and therefore protein: DNA ratio decreased), whereas jejunal RNA was significantly decreased in animals fed Triacetin.
No significant differences in crypt depth or mean villus height were observed (Lynch, Miles, and Bailey 1994).
Lynch and Bailey (1995) fed groups of eight male SpragueDawley rats the diets described in the preceding paragraph for 30 days, and the effect on total adiposity, fat distribution, and body composition was determined.
At study termination, animals of the LCT group weighed more than the animals in the Triacetin or control groups.
Feed consumption was not significantly different between the Triacetin and LCT groups; however, the controls ate less than animals of the test groups.
Also, energy intake was not significantly different between animals of the Triacetin and LCT groups, but it was significantly less in animals of the control group during weeks 2 to 4.
Animals of the Triacetin group had the least adipose tissue mass (measured in three depots) compared to the other groups; animals in the LCT group had the greatest adipose tissue mass.
Triacetin decreased adipocyte size, but total fat cell number did not differ among the groups.

ANIMAL TOXICOLOGY

Table 3 summarizes the acute toxicity findings as a function of the route of administration and animals used.
Acute Oral Toxicity Gast (1963) stated that the oral LD50 of Triacetin for male and female mice was 1.8 and 1.1 g/kg, respectively, although study details were not provided.
The acute oral toxicity of Triacetin was determined using a group of 10 mice (Lawrence, Malik, and Autian 1974).
The animals were given a single dose and observed for 7 days. The calculated oral LD50 for mice was 8.0 ml/kg.
Groups of five mice and five rats were used to determine the acute oral toxicity of Triacetin (Anstadt 1976).
The dose ranges tested were 1.6 to 25.6 and 0.8 to 12.8 g/kg for mice and rats, respectively.
The approximate LD50 was 3.2 to 6.4 g/kg for mice and 6.4 to 12.8 g/kg for rats.
Additional oral LD50 values were 3.2 to 6.1 g/kg for mice, 3.0 and >2.0 g/kg for rats, and >2.0 g/kg for rabbits.
Groups of eight Long-Evans rats were given as a continuous nasogastric infusion 462 kJ/kg of a diet containing either 16% or 32% Triacetin (Robertson et al. 1992).
No adverse effects, such as diarrhea or change in normal activity, were observed.

Acute Dermal Toxicity The acute dermal LD50 of Triacetin was determined using groups of five albino rabbits (Food and Drug Research Laboratories, Inc. 1976). A dose of 5 g/kg was applied to intact and abraded skin. The animals were observed for 7 days after dosing.
None of the animals died. The dermal LD50 of Triacetin for rabbits was >5 g/kg.
Additional dermal LD50 values were >20 ml/kg for guinea pigs and >2 g/kg for rabbits.

Acute Inhalation Toxicity

Triacetin, also known as Glyceryl Triacetate, is reported to function as a cosmetic biocide, plasticizer, and solvent in cosmetic formulations.
In 1998, it was reported to FDA that Triacetin was used in a total of 13 cosmetic formulations.
Industry reported that it was used at concentrations of 0.8% to 4%. Triacetin was affirmed as a GRAS human food ingredient by FDA.
The acute dermal LD50 of Triacetin was >5 g/kg for rabbits and >20 ml/kg for guinea pigs.
The oral LD50 for mice has been reported as 1.8 and 1.1 g/kg for males and females, respectively, and as 3.2 to 6.4 g/kg; it has been calculated as 8.0 ml/kg.

For rats, the oral LD50 was 6.4 to 12.8 g/kg. The inhalation LC50 was >1.721 mg/L for rats.
The SC LD50 was 2.3 cc/kg for mice and 2.8 cc/kg for rats. For mice, the IV LD50 values of 25% and 50% emulsions of Triacetin were 1.6 g/kg and 1.2 ml/kg, respectively.
For rabbits, the IV LD50 of Triacetin was 0.75, and for dogs, it was 1.5 to 2.0 ml/kg.
The IP LD50 for Triacetin in mice was determined to be 1.7 and 1.4 g/kg for males and females, respectively, and 0.8 to 1.6 g/kg; it was also calculated as 1.52 ml/kg for mice.
The IP LD50 for rats was 2.1 g/kg; in another study, it ranged from 0.8 to 1.6 g/kg.
The IM lethal dose was 1.5 cc/kg for guinea pigs.
In short-term feeding studies, Triacetin affected weight gain.
Triacetin was not toxic in short-term studies when administered via inhalation or parenterally or in subchronic studies when administered via feed or inhalation.
Triacetin was, at most, slightly irritating to guinea pig skin. However, in one study, it caused erythema, slight edema, alopecia, and desquamation.
Triacetin was not sensitizing in guinea pigs; however, test concentrations were not stated.
Triacetin caused some irritation in rabbit eyes.
Triacetin, with and without metabolic activation, was not mutagenic in the Ames assay or a suspension test.
It was also not mutagenic in an in vivo assay using Drosophila.
Triacetin (test concentrations not provided) was not an irritant or a sensitizer in a clinical maximization study, and only very mild reactions were seen in a Duhring-chamber test using a 50% dilution.
In humans, commercial Triacetin has caused ocular irritation but no injury.
DISCUSSION
The Cosmetic Ingredient Review (CIR) Expert Panel reviewed the safety of Triacetin for use as a cosmetic ingredient.
The Expert Panel considered the FDA affirmation of glycerides, including Triacetin, as a GRAS human food ingredients to be supportive of the overall safety of this ingredient.
The Expert Panel did recognize that reproductive and developmental toxicity data on Triacetin are absent from the report.
Because Triacetin is thought to be hydrolyzed to glycerol and acetic acid and these chemicals are not developmental toxins, the Expert Panel concluded that the use of Triacetin in cosmetics does not present a risk of reproductive or developmental toxicity.
The Expert Panel also noted that there are reports indicating that 1,2-glyceryl diesters (also known as 1,2-diacylglycerols) can affect cell growth and proliferation, raising the possibility of hyperplasia and/or tumor promotion.
This was an issue for discussion because, although Triacetin is a glyceryl triester, it is recognized that there would be some small amounts of glyceryl diesters present, some of which could be 1,2-glyceryl diesters.
The Panel concluded, however, that the effects of 1,2-glyceryl diesters on cell growth and proliferation require ester chains longer than two carbon atoms on the glycerin backbone.
Thus, any glyceryl 1,2-diacetyl esters present in Triacetin would be inactive in hyperplasia and tumor promotion.

CONCLUSION
On the basis of the animal and clinical data included in this report, the CIR Expert Panel concludes that Triacetin is safe as used in cosmetic formulations.

Triacetin, also known as Glyceryl Triacetate, is a cosmetic biocide, plasticizer, and solvent in cosmetic formulations, at concentrations ranging from 0.8% to 4.0%.
It is a commonly used carrier for flavors and fragrances.
Triacetin was affirmed as a generally recognized as safe (GRAS) human food ingredient by the Food and Drug Administration (FDA).
It is used as an inactive ingredient additive in some drug formulations.
It has been used as a plasticizer in the tests of acrylic polymer films for drug delivery.
Triacetin is not toxic to animals.
However, in one study, it caused erythema, slight edema, alopecia, and desquamation, and did cause some irritation in rabbit eyes.
Concentration of triacetin in consumer products is in the range of about 0.005-2 % for cosmetics, and has been reported to be as high as 15-33 % for one specific antifungal drug.

Excipient (pharmacologically inactive substance)

Medically reviewed by Drugs.com. Last updated on June 19, 2020.

What is it?
Triacetin (C9H14O6), also known as glyceryl triacetate, is pharmaceutical excipient used in manufacturing of capsules and tablets, and has been used as a humectant, plasticizer, and solvent.
It is a liquid, and has been approved by the FDA as a food additive.
Triacetin is a water-soluble short-chain triglyceride that may also have a role as a parenteral nutrient according to animal studies.
It is also used in the perfume and cosmetic industries.

Triacetin is listed on the FDA Generally Regarded As Safe (GRAS) List.
According to the FDA, triacetin has been found to be non-toxic in long-term feeding tests in rats at levels that were several orders of magnitude greater than those to which consumers are exposed.
Additionally, in a toxicology report from 2002, triacetin and a group of related triglycerides did not represent a hazard to human health based on the anticipated daily intake of 7.8 mg/day/adult, and other available data.
One case of skin toxicity (allergic contact eczema) due to industrial use in cigarette filter production has been reported.

There is no evidence in the available information on triacetin that demonstrates or suggests reasonable grounds to suspect a hazard to the public when they are used at levels that are now current or that might reasonably be expected in the future

Triacetin (Glycerol triacetate, Glyceryl triacetate, Glycerin triacetate, 1,2,3-Triacetoxypropane) is a triglyceride that is used as an antifungal agent.

However, in one study, it caused erythema, slight edema, alopecia, and desquamation, and did cause some irritation in rabbit eyes.
Triacetin was not sensitizing in guinea pigs. Triacetin was not an irritant or a sensitizer in a clinical maximization study, and only very mild reactions were seen in a Duhring-chamber test using a 50% dilution.
In humans, Triacetin reportedly has caused ocular irritation but no injury.
Triacetin was not mutagenic.
Although there were no available reproductive and developmental toxicity data, Triacetin was quickly metabolized to glycerol and acetic acid and these chemicals were not developmental toxins.

Reports of 1,2-glyceryl diesters, which may be present in Triacetin, affecting cell growth and proliferation raised the possibility of hyperplasia and/or tumor promotion.
The Cosmetic Ingredient Review (CIR) Expert Panel concluded, however, that the effects of 1,2-glyceryl diesters on cell growth and proliferation require longer ester chains on the glycerin backbone than are present when acetic acid is esterified with glycerin, as in Triacetin.
On the basis of the available information, the CIR Expert Panel concluded that Triacetin is safe as used in cosmetic formulations.

Triacetin as a Secondary PVC Plasticizer

The use of biobased plasticizers with low toxicity and good compatibility with polyvinyl chloride (PVC) has become more attractive in the recent years in contrast with phthalate derivatives.
In this study, a glycerol derivative plasticizer (triacetin—TAG) was tested as a secondary plasticizer for PVC.
Triacetin was added to PVC formulations from 10 up to 20 phr.
The increase of the plasticizer content had a great influence on the properties of PVC samples.
The good miscibility and therefore the efficient plasticization action of the Triacetin were supported by DMA results, since narrow peaks of tan (δ) curves and reduction of the Tg values for the samples were observed.
The ensuing PVC demonstrated good rheological properties and thermal stability up to 200 °C.
Finally, the presence of TAG reduces the hardness of materials and does not increase their density.

In technical applications triacetin is applied as a highly effective plasticizer for coatings and adhesives, as an additive for special hardeners or also for the production of cigarette filters on the basis of cellulose acetate (filter tow).
Other fields of application include solvent in foundry, ink and printing ink industry.

Triacetin complies with the European Pharmacopoeia and is approved in the EU as a food additive E 1518.
In the food and perfume industry, among other applications, it is used as a solvent and solubilizer for fragrances and flavors, or as a plasticizer for chewing gum.
