FAQ - Technical & Supply Chain
-
Q:
What is Triacetin CAS 102-76-1?
A: Triacetin, also called Glycerol Triacetate or Glyceryl Triacetate, is the triester of glycerol and acetic acid. It has CAS 102-76-1, EINECS 203-051-9, molecular formula C9H14O6 and molecular weight about 218.20. It is normally a colorless to pale, low-odor oily liquid with a boiling point around 258-260 deg C and density around 1.16 g/cm3. -
Q:
Are Triacetin, Glycerol Triacetate and Glyceryl Triacetate the same material?
A: Yes. These names all identify CAS 102-76-1, but they do not define a commercial grade. Food-additive, pharmaceutical, cosmetic and tobacco-filter grades may have different assay bases, monograph limits and documentation, so the intended application should be stated when requesting a quotation. -
Q:
What is Triacetin used for?
A: Triacetin is used as a food-additive solvent and humectant, a pharmaceutical excipient and film-coating plasticizer, a fragrance and cosmetics solvent, and a plasticizer for cellulose acetate including cigarette filters. It is also evaluated as a biodegradable or hydrophilic plasticizer and solvent in coatings, inks and other polymer systems. -
Q:
Which specifications should be confirmed for Triacetin?
A: Key parameters are assay, water, acidity, color, density, refractive index and distillation range. Typical values include assay not less than 99%, density about 1.155-1.165 at 20 deg C, refractive index about 1.429-1.432 and low Pt-Co color, but food and pharmaceutical grades may require compendial or regulatory limits. -
Q:
How should Triacetin be stored and handled?
A: Store Triacetin in tightly closed, compatible containers in a cool, dry and ventilated area away from strong oxidizers, heat and ignition sources. Keep containers sealed when not in use to avoid moisture ingress and contamination, and confirm packaging, unloading and safety requirements before bulk transfer.
