Dihydroxyacetone

Other names: glycerol, DHA

Harm score: 2 (Derivatives of natural substances)

Dihydroxyacetone, also known by the abbreviation DHA and the name glycerone, is a ternary substance characterized by its formula C3H6O3. It is a sweet, crystalline substance that is formed as a breakdown product of glycerol under the influence of enzymes. It is one of the best known and most important compounds in the cosmetics and food industries.

DHA is particularly valued in the field of cosmetics, where it is commonly used as the main ingredient in self-tanning products. The dihydroxyacetone in these products reacts with amino acids in the skin, causing it to darken. The resulting bronze effect is temporary and fades as dead skin cells slough off. The name DHA thus often appears on the labels of self-tanning lotions and sprays. Due to its natural sweetness, DHA is also used in the food industry as a sweetener, especially in low-calorie foods. However, due to its reactivity, DHA is not very stable and therefore needs to be stored in a cool, dark place to prevent its deterioration.
