The Development History of 1,3-Dihydroxyacetone DHA
1. Introduction to 1,3-Dihydroxyacetone DHA 1,3-Dihydroxyacetone (DHA) is a white crystalline powder known for its excellent water solubility and stability. Its chemical formula is C3H6O3, with a molecular weight of 90.08 g/mol. The structure of DHA consists of a three-carbon chain, with hydroxyl (-OH) groups attached to the 1st and 3rd carbon atoms, and a carbonyl (=O) group attached to the 2nd carbon atom. DHA is most renowned for its application in the cosmetics industry, particularly in self-tanning products.
