1,3-Dihydroxyacetone Usage And Synthesis
Dihydroxyacetone has a characteristic sweet, cooling aroma.
A derivative of naturally occurring starch
1,3-Dihydroxyacetone can be used as artificial tanning agent.
1,3-Dihydroxyacetone (DHA) is a self-tanning agent used in cosmetics designed to provide a tanned appearance without the need for sun exposure. It is also a uV protector and a color additive. As a self-tanning agent, it reacts with amino acids found on the skin’s epidermal layer. Its effects last only a few days as the color it provides fades with the natural shedding of the stained cells. Reportedly, it works best on slightly acidic skin. DHA, when combined with lawsone, becomes an FDA Category I (approved) uV protectant. In 1973, the FDA declared that DHA is safe and suitable for use in cosmetics or drugs that are applied to color the skin, and has exempted it from color additive certification.
ChEBI: A ketotriose consisting of acetone bearing hydroxy substituents at positions 1 and 3. The simplest member of the class of ketoses and the parent of the class of glycerones.
Usually produced commercially from Bacillus macerans or Bacillus circulans fermentation of starch or starch hydrolysate
Taste threshold values
Reported to have a taste threshold value lower than that of sucrose with a detection level of 3.9 to 27 ppm and a recognition level of 11 to 52 ppm.
Mutation data reported. When heated to decompositionit emits acrid smoke and irritating vapors.
