1,3-Dihydroxyacetone

Dihydroxyacetone, or DHA, also known as glycerone, is a simple carbohydrate (a triose) with formula C 3H 6O 3.
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.
