Dihydroxyacetone

Dihydroxyacetone (DHA, CAS 96-26-4) is a simple three-carbon ketone sugar commercially available under trade names including Otan, Soleal, Dihyxal, Oxantin, and Oxatone. It carries no E-code designation and is classified under HS code 29141900. It occurs naturally in small quantities in certain fermented products and is produced industrially via glycerol fermentation.

In personal care formulations, DHA reacts with free amino groups in skin proteins through a Maillard-type reaction, producing brown melanoidin pigments that simulate a tan without UV exposure. In food applications it functions as a flavorant and mild acidulant, contributing caramel-like notes. In textile and leather processing, it acts as a crosslinker, forming covalent bonds with collagen or cellulosic fibers to improve dimensional stability.

DHA is supplied as a white powder in food-grade and cosmetic-grade specifications, with quality benchmarks aligned to FCC and REACH compliance requirements. Standard packaging includes fiber drums and multi-layer bags. Suppliers should confirm grade suitability for food versus topical applications prior to procurement.
