GLYCERINE TRIACETATE E1518

Glycerine Triacetate E1518 is the commercial name under which triacetin (CAS No 102-76-1, C9H14O6), the triacetate ester of glycerine, is traded in technical, food and pharmaceutical qualities, a clear, colorless liquid whose value for the buyer depends above all on choosing the right grade, purity, acidity and documentation for the intended use.
Triacetin is bought by very different industries, from cigarette filter and foundry producers to flavor houses, chewing gum makers, pharmaceutical coating specialists and perfumers, and each of them looks at a different part of the specification, which is why the same molecule is offered in several distinct qualities.
Glycerol triacetate performs as a low-volatility solvent, carrier, plasticizer, humectant and ester hardener because its three acetate groups give it medium polarity and good solvency, while its slow hydrolysis to glycerine and acetic acid makes it both safe in food and pharmaceuticals and useful as a curing agent in alkaline binders.

Eur.

Glycerine triacetate and glycerin triacetate are trade names widely used in purchasing lists and supplier catalogues. Glycerol triacetate and glyceryl triacetate are chemical names, triacetin is the common name and the INCI and pharmacopoeial name, and propane-1,2,3-triyl triacetate is the IUPAC name. All of them refer to CAS 102-76-1. Grade descriptors such as Technical Grade, Food Grade, FCC, USP and Ph. Eur. indicate the quality standard of the delivered material.
When ordering Glycerine Triacetate E1518, it is important not to confuse it with glycerine itself, with monoacetin or diacetin (partially acetylated glycerine), or with blends of acetins sold for foundry use. The CAS number and assay on the certificate of analysis confirm that the product is triacetin.

WHAT IS GLYCERINE TRIACETATE E1518?

From a purchasing perspective, Glycerine Triacetate E1518 is one substance with several markets. Technical-grade material goes mainly into cigarette filter tow, foundry sand binders, cellulose ester plastics, lacquers and inks. Food-grade material is used as additive E1518, mainly as a carrier for flavorings and as a softener in chewing gum. Pharmaceutical-grade material serves as a plasticizer and solvent in coatings, capsules and other dosage forms. Cosmetic-grade material is used under the INCI name Triacetin in perfumes, nail products and skin care.
These grades share the same chemistry but differ in purity, odor, impurity limits, manufacturing controls and documentation. A technical product may perform perfectly in a foundry but cannot be used in food or medicines, while a pharmaceutical grade is usually more expensive than necessary for industrial use.

For buyers, the key to sourcing Glycerine Triacetate E1518 is to define the application first and then select the grade and specification that match it.
For producers, a consistent specification, especially for acidity, water and odor, ensures stable processing, whether in filter making, mold production or flavor manufacture.
Glyceryl triacetate can be supplied for filter tow plasticization, ester-cured foundry binders, cellulose plastics and coatings, flavor carriers and chewing gum, pharmaceutical coatings and capsules, perfumes and cosmetics, and other specialty uses.

The glycerine triester is the product of complete esterification of glycerine with acetic acid or acetic anhydride. Each of the three hydroxyl groups of glycerine carries an acetyl group, giving C3H5(OCOCH3)3.
Industrial production uses either acetic acid with an acid catalyst and continuous water removal, or acetic anhydride, which reacts faster and forms acetic acid as a by-product. The crude product is neutralized and purified by vacuum distillation. Food and pharmaceutical grades undergo additional purification and stricter controls.
The result is a clear, colorless, slightly oily liquid with a faint odor, a slightly sweet taste at low concentrations, a boiling point of about 258–259 °C and a melting point of about −78 °C. Triacetin is moderately soluble in water (about 61 g/L at 20 °C) and miscible with ethanol, acetone and many other organic solvents.

CHEMICAL STRUCTURE AND WHY IT MATTERS FOR QUALITY

The three ester bonds in Glycerine Triacetate E1518 are the reason for both its usefulness and its main quality risk.

Ester groups and solvency: They give medium polarity, which allows Glycerine Triacetate E1518 to dissolve flavors, fragrances, dyes, resins and cellulose esters.
Ester groups and hydrolysis: The same bonds can slowly react with water, especially in the presence of acids, bases or heat, forming acetic acid and partial acetins. This is why acidity and water content are the key specification parameters.
No double bonds: Glycerine Triacetate E1518 does not oxidize or become rancid, so color and odor usually remain stable when storage conditions are correct.

HOW DOES GLYCERINE TRIACETATE E1518 WORK AT THE MOLECULAR LEVEL?
 
Glycerine Triacetate E1518, also known as triacetin, is the triester formed when all three hydroxyl groups of glycerol are esterified with acetic acid. With no free hydroxyl groups left, the molecule is a small, moderately polar ester that cannot donate hydrogen bonds but can accept them through its carbonyl oxygens. This balance between polar ester groups and a compact hydrocarbon backbone explains how it behaves as a solvent, plasticiser and carrier.
 
Solvent and carrier action: Triacetin dissolves many flavour and fragrance compounds that are poorly soluble in water, such as esters, aldehydes and essential oil components, because it interacts with them through dipole–dipole forces and weak dispersion forces. At the same time, it mixes with ethanol and has limited solubility in water. In flavour systems, the triester therefore acts as a bridge between hydrophobic aroma molecules and more polar food matrices, holding volatile compounds in solution and helping distribute them evenly in the final product.
 
Plasticising effect: When the ester is mixed with a polymer, its small molecules move into the spaces between polymer chains. The carbonyl groups interact with polar sites on the polymer and partly replace chain-to-chain interactions. Chains slide past each other more easily, the glass transition temperature falls and the material becomes softer and more flexible. This mechanism underlies the use of Glycerine Triacetate E1518 in cellulose acetate materials, chewing gum bases and polymer coatings for tablets.
 
Bonding of cellulose acetate fibres: In cellulose acetate filter tow, the ester is applied to the fibres and partially solvates their surfaces. At points where fibres touch, the softened polymer from neighbouring fibres flows together. As the plasticiser redistributes into the fibre bulk, the contact points harden into bonds, giving a firm, porous structure without a separate adhesive.
 
Humectant behaviour: The carbonyl oxygens of triacetin can accept hydrogen bonds from water, so the molecule holds some moisture in a product and slows drying. Since it lacks the hydroxyl groups of glycerol, this effect is much weaker than that of glycerol itself, and the ester remains more compatible with oily and flavour components.
 
Hydrolysis: The ester bonds can be cleaved by water, a process accelerated by acids, bases and esterase or lipase enzymes. Each hydrolysis step releases one molecule of acetic acid, passing through diacetin and monoacetin until glycerol and acetic acid remain. Moisture and high temperature during storage favour this reaction, which can slowly raise acidity and change the odour of the product.
 
Ester hardening in foundry binders: In sodium silicate sand binders, glycerine triacetate is used as an ester hardener. In the strongly alkaline silicate solution, the ester hydrolyses and the acetic acid released neutralises part of the alkali. The local fall in pH causes the silicate to polymerise into a silica gel that binds the sand grains together. The rate of ester hydrolysis controls the setting time of the mould.
 
Mild antifungal action on skin: The same enzymatic hydrolysis can occur on skin, where esterases release acetic acid from the triester. The resulting local fall in pH creates less favourable conditions for fungal growth, this mechanism is the basis for its historical use in topical antifungal preparations.
 
Behaviour in the body: After ingestion, digestive and tissue esterases hydrolyse the molecule into glycerol and acetic acid. Both are normal metabolic substances: glycerol enters carbohydrate and lipid metabolism, and acetate is converted to acetyl-CoA and used for energy. Evaluations of E1518 are therefore based largely on these two breakdown products.
 
Solvency, plasticising strength and hydrolytic stability depend on concentration, temperature, moisture, pH and the other components of the system. Glycerine Triacetate E1518 dosage and process conditions should therefore be confirmed through laboratory trials.

HOW DOES GLYCERINE TRIACETATE E1518 WORK?

In polymers, Glycerine Triacetate E1518 increases chain mobility and flexibility. In filter tow, it softens fiber surfaces and bonds fibers together. In alkaline foundry binders, it hydrolyzes to acetic acid and lowers the pH, causing the binder to set. In flavors and fragrances, it dissolves and retains volatile components because it evaporates very slowly. In foods and pharmaceuticals, it is metabolized to glycerine and acetic acid.
