Quick Search
Glyceryl Triacetate E1518 is the food, pharmaceutical and cosmetic-grade form of triacetin, the glycerol ester of acetic acid (CAS No 102-76-1, C9H14O6), a clear, almost odorless liquid used as a carrier solvent and humectant for flavors, a softener in chewing gum and confectionery, a plasticizer in tablet coatings and capsules, and a solvent and fixative in fragrances and personal care products.
Triacetin is widely chosen in consumer-related products because it is approved as food additive E1518, listed in the major pharmacopoeias, has a very low toxicity profile and is broken down in the body into glycerol and acetic acid, two substances that are already part of normal metabolism.
Glycerol triacetate works by combining moderate polarity with low volatility: it dissolves flavors, essential oils and active ingredients that are poorly soluble in water, keeps them evenly distributed and releases them slowly, while softening polymers such as gum bases and film coatings.

COMMON PRODUCT & CHEMICAL NAMES OF GLYCERYL TRIACETATE E1518:
Glyceryl Triacetate E1518, Glyceryl Triacetate, Triacetin, Triacetin E1518, Glycerol Triacetate, Glycerin Triacetate, Triacetinum, Triacetine, E1518, INS 1518, Propane-1,2,3-triyl Triacetate, 1,2,3-Triacetylglycerol, Triacetylglycerol, 1,2,3-Triacetoxypropane, Triacetyl Glycerin, Triacetin FCC, Triacetin USP, Triacetin Ph. Eur., Enzactin, Fungacetin
In food labeling, Glyceryl Triacetate E1518 appears as "triacetin" or E1518. In cosmetic ingredient lists, the INCI name Triacetin is used. Pharmacopoeias list the substance as Triacetin (Triacetinum in Latin). Glyceryl triacetate, glycerol triacetate and glycerin triacetate are chemical names describing the same molecule. Enzactin and Fungacetin are historical names of topical antifungal preparations based on triacetin.
Glycerine triacetate is not the same as glycerol monoacetate (monoacetin) or glycerol diacetate (diacetin), and it should not be confused with triethyl citrate (E1505), another common food-grade plasticizer and carrier.
WHAT IS GLYCERYL TRIACETATE E1518?
Triacetin is a short-chain triglyceride in which glycerol is esterified with three acetic acid molecules. Its structure can be written as C3H5(OCOCH3)3. Unlike common fats and oils, which carry long fatty acids, Glyceryl Triacetate E1518 carries the shortest possible acyl group, which gives it a liquid form, moderate water solubility and good solvency for polar and medium-polar substances.
Glycerol triacetate is produced by esterifying glycerol with acetic acid or acetic anhydride under controlled conditions, followed by purification steps such as neutralization and vacuum distillation. Food and pharmaceutical grades are refined to high purity, with low acidity, low water content and strict limits for heavy metals and arsenic.
In the body, Glyceryl Triacetate E1518 is hydrolyzed by esterases into glycerol and acetic acid. Both are normal metabolic substances, which is one reason why triacetin has a long history of safe use in food and pharmaceuticals. It has even been studied as a potential energy source in parenteral nutrition and in long-duration space mission food systems.
Glycerine triacetate has a mild, slightly sweet taste at concentrations below a few hundred ppm, but becomes bitter at higher concentrations. Its odor is faint.
In the flavor industry, Glyceryl Triacetate E1518 is a classic carrier solvent. Many flavor components, essential oils and oleoresins are only poorly soluble in water and in propylene glycol, but they dissolve well in triacetin. Because it evaporates very slowly, flavors carried in Glyceryl Triacetate E1518 are better protected during processing and storage. It is especially useful for alcohol-free flavor concentrates.
In chewing gum and confectionery, Glyceryl Triacetate E1518 softens the gum base and keeps it pliable, and it helps maintain moisture and texture during shelf life. In bakery and confectionery products, it can support texture and reduce drying.
In pharmaceuticals, Glyceryl Triacetate E1518 is a plasticizer for film coatings and gelatin capsules, a solvent for active ingredients in liquid and semi-solid dosage forms and a humectant. In cosmetics and fragrances, it serves as a solvent, plasticizer and fixative in perfumes, deodorants, nail products and skin care.
For formulators, Glyceryl Triacetate E1518 offers broad regulatory acceptance, neutral sensory properties at typical levels, good solvency and easy liquid handling.
For consumers, it contributes to longer-lasting flavors, soft chewing gum, flexible and crack-free tablet coatings and stable fragrances.
The glycerol triester can be evaluated in flavor concentrates, beverages, chewing gum, confectionery, bakery fillings, tablet and capsule coatings, soft capsules, topical preparations, perfumes, deodorants, nail polishes and skin care products, and in technical grades also in filter tow, foundry binders and plastics.
GLYCERYL TRIACETATE E1518 IN FOOD AND FLAVORS
Glyceryl Triacetate E1518 is one of the established carriers and solvents for flavorings.
TYPICAL FOOD AND FLAVOR USES:
Carrier and solvent for flavor concentrates and essences
Solvent aid for alcohol-free oleoresin and essential oil concentrates
Humectant and softener in chewing gum
Texture and moisture retention in some confectionery and bakery products
Carrier for food colors and other lipophilic additives
Plasticizer in edible films and coatings
Because flavor compounds dissolve well in Glyceryl Triacetate E1518 and it evaporates slowly, flavors are retained better during baking and storage than with more volatile carriers such as ethanol.
Use of E1518 must follow the food additive regulations of the target market. In the EU, it is authorized mainly as a carrier for flavorings and in specific food categories, in the US, triacetin is affirmed as generally recognized as safe (GRAS). Only food-grade material meeting the applicable purity criteria should be used.
GLYCERYL TRIACETATE E1518 IN PHARMACEUTICALS
Pharmaceutical-grade Glyceryl Triacetate E1518 is a widely used excipient.
TYPICAL PHARMACEUTICAL USES:
Plasticizer in aqueous and organic film coatings of tablets and pellets
Plasticizer in enteric and modified-release coatings
Plasticizer in hard and soft gelatin capsules
Solvent and co-solvent for active ingredients in oral and topical formulations
Humectant in semi-solid preparations
Topical antifungal agent (historically), based on enzymatic release of acetic acid on the skin
In film coatings, Glyceryl Triacetate E1518 lowers the glass transition temperature of the coating polymer, prevents cracking and improves film flexibility. It is commonly used with cellulose-based polymers and some methacrylate copolymers. Typical plasticizer levels range from about 10 to 30 % of the polymer weight, depending on the polymer and coating process.
Pharmaceutical-grade material should comply with the relevant monograph (for example Ph. Eur. or USP-NF Triacetin), and the finished product must be approved according to medicinal product regulations.

CHEMICAL STRUCTURE AND MOLECULAR PROPERTIES OF GLYCERYL TRIACETATE E1518
All three hydroxyl groups of glycerol in Glyceryl Triacetate E1518 are converted into acetate esters. The result is a small, compact molecule with three polar ester groups and no free hydroxyl groups.
This structure leads to properties that are important in food, pharmaceutical and cosmetic formulations:
Moderate polarity: dissolves many flavors, essential oils, fragrances, colors and drugs.
Partial water solubility: about 61 g/L, enough to interact with aqueous systems but not fully water-miscible.
Low volatility: high boiling point (about 258–259 °C) and low vapor pressure, which keeps flavors and fragrances in place longer.
Hydrolysis by esterases: in the body or on skin, enzymes slowly split the molecule into glycerol and acetic acid.
Oxidative stability: no double bonds, so the product does not turn rancid.

Glyceryl Triacetate E1518 and triethyl citrate (E1505): Another food and pharmaceutical plasticizer and carrier with slightly different solvency.
Glyceryl Triacetate E1518 and glycerol: Glycerol is a stronger humectant but a poor solvent for lipophilic substances.
Glyceryl Triacetate E1518 and medium-chain triglycerides: MCT oil carries lipophilic flavors well but has different polarity and no plasticizing effect on polar polymers.
Glyceryl Triacetate E1518 and dibutyl sebacate or polyethylene glycol: Alternative plasticizers in pharmaceutical coatings.
HOW DOES GLYCERYL TRIACETATE E1518 WORK AT THE MOLECULAR LEVEL?
Glyceryl Triacetate E1518 is a clear, low-volatility liquid ester in which glycerol carries three acetyl groups. Its effect is easiest to understand by following the molecule through the life of a product: what it does when it is mixed in, what changes during processing, how it behaves in storage, and what happens when the product is finally used or consumed.
During mixing – dissolving and dispersing: Triacetin has three polar ester groups but no free hydroxyl groups, so it attracts semi-polar molecules without binding water strongly. When aroma compounds, colours or active ingredients with limited water solubility are added, they are surrounded by the ester molecules through dipole–dipole and dispersion interactions and stay dissolved in a single liquid phase. This makes glyceryl triacetate a practical carrier: concentrated actives are diluted into a liquid that can be dosed accurately and blended evenly into larger batches.
During processing – softening polymers: When the ester comes into contact with polymers such as cellulose acetate, gum base polymers or film-forming coating polymers, its small molecules penetrate the amorphous regions between chains. Carbonyl groups interact with polar groups on the polymer, weakening chain-to-chain attraction and increasing free volume. The polymer’s glass transition temperature falls, so the material can be shaped, stretched or coated without cracking. In cellulose acetate filter tow, the softened fibre surfaces fuse where fibres touch and then set as the plasticiser migrates inward, producing a bonded porous structure.
During processing – setting reactions: In strongly alkaline systems, the ester bonds are attacked by hydroxide ions. In sodium silicate foundry binders, this controlled hydrolysis releases acetic acid, which neutralises part of the alkali and causes the silicate to form a silica gel between sand grains. Because the reaction proceeds at a predictable rate, Glyceryl Triacetate E1518 acts as a timed hardener rather than an instant one.
During storage – stability and slow change: Under dry, neutral and moderate-temperature conditions, the three ester bonds are fairly stable and the liquid keeps its properties for long periods. Moisture, heat and traces of acid or alkali promote stepwise hydrolysis to diacetin, monoacetin and finally glycerol, releasing acetic acid at each step. A slow rise in acidity or a vinegar-like note is therefore the typical sign of ageing. Within finished products, the carbonyl oxygens also hold a small amount of water, which slightly slows moisture loss without making the product sticky.
During storage – plasticiser migration: Because the molecule is small and mobile, it can slowly redistribute inside a polymer or move toward surfaces and into neighbouring materials. In coated tablets, gum or fibre products, this migration gradually changes flexibility and hardness until a new equilibrium is reached, which is why plasticiser level and packaging are considered together.
During use – release of aroma and actives: In foods and flavoured products, the carrier gradually gives up the aroma molecules it holds as the product is heated, chewed or diluted. In topical preparations, skin esterases can split the ester and release acetic acid, lowering local pH, this is the basis of its traditional role in mild antifungal products.
After consumption – metabolism: In the digestive tract and tissues, esterases hydrolyse glyceryl triacetate into glycerol and acetic acid. Glycerol joins normal carbohydrate and fat metabolism, and acetate is converted into acetyl-CoA and used for energy. For this reason, evaluations of E1518 are based largely on these two familiar metabolites.
At each stage, the result depends on concentration, temperature, moisture, pH, contact time and the other components of the system. Glyceryl Triacetate E1518 dosage and process conditions should therefore be confirmed through laboratory trials.
