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.

Functions
Antimicrobial
Keeps your product from growing bacteria, mold, or yeast. Without these, that jar of cream becomes a petri dish in about a week.
Film Forming
Creates a physical seal on skin to lock moisture in and keep irritants out. The "slugging" ingredient — barrier protection.
Plasticiser
Solvent
Dissolves other ingredients so they distribute evenly in the formula. Often the invisible "base" everything else is mixed into.
Draws water to skin
Fights acne
Causing bacteria
Traditional Use
Developed in the 19th century as a plasticizer and solvent. Adopted by the cosmetics industry in the 20th century primarily as a humectant and preservative booster in nail polishes and other formulations.
