Usage

Description

[R,(-)]-1-(2,4-Dihydroxyphenyl)-2-(4-methoxyphenyl)-1-propanone, commonly known as (-)-Erythrulose, is a chemical compound derived from natural sources such as sugar cane and sugar beets. It is widely recognized for its use as a self-tanning agent in the cosmetic industry, offering a natural-looking tan on the skin. Erythrulose reacts with the amino acids in the outer layer of the skin, leading to a color change and a temporary tan that lasts for several days. It is considered safe for use in cosmetic products and is often preferred for its ability to produce a more even and natural-looking tan compared to dihydroxyacetone (DHA).
