| GMO | GMONo data available |
| HS Code | 2914406000 |
| INCI | 1,3-dihydroxy-2-propanone |
| Manufacture | DHA is produced by bacterial-driven enzymatic degradation of natural glycerin in the presence of sorbitol. |
| Preservation | Preservative-free |
| Purity Grade | No purity grade applicable |
| Raw Material Source | Glycerin, sorbitol |
| Uses | Can be added to formulations as is, usual final concentration 2-12%, lower concentration for lighter tan or face, higher concentration for darker shade and body. DHA may lose its tanning effect (or induce discolorations) when combined with alpha-hydroxy acids, titanium dioxide, zinc oxide, iron oxide pigments, or certain perfumes. Avoid using amino acids, proteins, peptides, EDTA. Final product should be in the pH range between 3.5 and 5, this will prevent it from early degradation. Usually combined with erythrulose for a deeper, natural looking tan. For external use only. |
Dihydroxyacetone, commonly referred to as DHA, is a simple saccharide predominantly utilized in self-tanning formulations. This compound, characterized by its white powder form and distinctive odor, is easily soluble in water as well as in water-ethanol mixtures. It is typically included in various product formulations, such as emulsions, lotions (both aqueous and aqueous/alcoholic), and gels. The concentration of dihydroxyacetone in tanning products generally ranges from 2% to 5%, allowing for effective and consistent application.
What is Dihydroxyacetone and how is it used in self-tanning products?
Dihydroxyacetone, also known as 1,3-Dihydroxy-2-Propanone, is a simple saccharide commonly used in self-tanning preparations. It is a white powder with a characteristic odor and is readily soluble in water and mixtures of water and ethanol. In self-tanning products, it is typically included in formulations such as emulsions, lotions (both aqueous or aqueous/alcoholic), and gels. The concentration of Dihydroxyacetone in these products usually ranges from 2 to 5%.
How does Dihydroxyacetone work to create a tan?
Dihydroxyacetone reacts with the amino acids in the outermost layer of the skin, leading to the formation of brown pigments called melanoidins. This reaction mimics the appearance of a natural tan without exposure to UV rays. The resulting color generally develops within a few hours after application and can last for several days, gradually fading as the dead skin cells are naturally exfoliated.
Are there any specific storage or handling instructions for Dihydroxyacetone-based products?
Dihydroxyacetone-based products should be stored in a cool, dry place away from direct sunlight to maintain their effectiveness. It's important to ensure the container is tightly sealed to prevent any moisture from affecting the product. For handling, follow normal procedures for applying cosmetic products, and avoid contact with fabrics as the compound may stain.
