Frequently Asked Questions
What is 1,3-dihydroxyacetone (DHA) used for?
DHA (CAS 96-26-4) is a ketotriose best known as the active browning agent in sunless-tanning formulations, where it reacts with amino acids at the skin surface to develop color. Beyond cosmetics it serves as a chemical intermediate, a humectant, and an emulsifier.
What is the chemical formula of dihydroxyacetone?
The molecular formula is C3H6O3 and the CAS number is 96-26-4. It is the simplest ketose (a ketotriose) and is classified as a specialty additive.
Is dihydroxyacetone the same as dihydroxyacetone phosphate?
No. Dihydroxyacetone (CAS 96-26-4) is the free triose, while dihydroxyacetone phosphate (DHAP) is its phosphorylated metabolic form and a distinct compound. The bulk product supplied here is the free DHA; specify by CAS to avoid confusion.
Is dihydroxyacetone water soluble?
DHA is highly soluble in water, which supports its use in aqueous self-tan formulations and as a humectant. Refer to the technical data sheet for exact solubility and grade specifications.
What is the bulk price of dihydroxyacetone?
Bulk pricing depends on grade, volume, and packaging. Submit a bulk RFQ with your target quantity for a current quote, along with a CoA and SDS.
What is the REACH and TSCA regulatory status of Dihydroxyacetone (DHA)?
Dihydroxyacetone (DHA) (CAS 96-26-4) is subject to U.S. TSCA Inventory requirements; supplying it into the EU requires valid REACH registration ((EC) No 1907/2006). RawSource cannot verify a third-party supplier's registrations — buyers should require documented TSCA and REACH compliance for their jurisdiction and volume (EC 202-494-5).
