What is Triacetin?

Plain description, key identifiers and synonyms

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 solvent, an adjuvant, a fuel additive, a food emulsifier, a plant metabolite, a food humectant, a food additive carrier and an antifungal drug. It is functionally related to an acetic acid.
