  • Applications

    Dihydroxyacetone (CAS 96-26-4) is widely used in cosmetics and personal care as a self-tanning agent, reacting with skin amino acids to form pigment. It also serves as a chemical intermediate and building block in industrial manufacturing, used for the synthesis of diols and other functional derivatives. In the polymers/plastics field, DHA can function as a diol-functional component for polymerization. Additionally, it may appear in formulation recipes for cleaning or household products as a diol-based solvent or additive, depending on formulation requirements and local regulations.
