General Description |
Dihydroxyacetone (DHA) is a browning ingredient widely used in cosmetics such as sunless tanning formulations. It participates in a chemical staining reaction called Milliard reaction in which it reacts with the amino groups of proteins to result in a mixture of high molecular weight pigments.Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards. |
|
Safety Profile |
Mutation data reported. When heated to decompositionit emits acrid smoke and irritating vapors. |
|
Consumer Uses |
This substance is used in the following products: cosmetics and personal care products and perfumes and fragrances. Other release to the environment of this substance is likely to occur from: indoor use as processing aid and outdoor use as processing aid. |
