INTRODUCTION

1,3-Dihyrdoxyacetone is a hygroscopic, white powder with a minty odor. It is abundantly found in nature as derivative of starch and is an intermediate product of fructose metabolism.  Acronymed as DHA, it is at large used in the cosmetic industry.

The sunless tanning industry has experienced rapid growth due to public education on the dangers of ultraviolet radiation on skin and improvements in products. Dihydroxyacetone (DHA) is a 3-carbon sugar allowed by the Food and Drug Administration (FDA) as a color additive in sunless tanning products.

Manufacture
DHA is manufactured by bacterial fermentation of glycerine and alternatively from formaldehyde using formose reaction.
