Dihydroxyacetone (CAS 96-26-4)

Dihydroxyacetone, also known as glycerone, is a simple saccharide (a triose) with formula C3H6O3.

DHA is primarily used as an ingredient in sunless tanning products. It is often derived from plant sources such as sugar beets and sugar cane, and by the fermentation of glycerin.

DHA is a hygroscopic white crystalline powder. It has a sweet cooling taste and a characteristic odor. It is the simplest of all ketoses and has no chiral center or optical activity. The normal form is a dimer (2,5-bis(hydroxymethyl)-1,4-dioxane-2,5-diol) which is slowly soluble in one part water and 15 parts ethanol. When freshly prepared, it reverts rapidly to the monomer in solution.
