In today’s beauty and personal care industry, safety and sustainability are at the forefront of consumer demands. While the desire for a sun-kissed glow remains strong, concerns about UV exposure—linked to sunburn, premature aging, and skin cancer—have driven a major shift toward sunless tanning alternatives. Among these solutions, 1,3-dihydroxyacetone (DHA, CAS 96-26-4) has become the most trusted self-tanning ingredient, delivering a natural bronze tone without harmful UV rays. As the primary DHA tanning agent in sunless tanning products, it plays a critical role in modern cosmetic formulations worldwide.
What is 1,3-Dihydroxyacetone?
1,3-Dihydroxyacetone (CAS 96-26-4) is a naturally derived carbohydrate, produced via the fermentation of glycerol. It appears as a white crystalline powder with excellent solubility in water and alcohol, making it easy to incorporate into various cosmetic formulations. Recognized as safe for topical use, DHA is the only FDA-approved active self-tanning ingredient, reinforcing its position as a reliable and effective component in the sunless tanning industry.
Chemical Name: 1,3-Dihydroxyacetone
CAS Number: 96-26-4
Appearance: White crystalline powder
Function: Key DHA tanning agent
How Does 1,3-Dihydroxyacetone Work?
The effectiveness of 1,3-dihydroxyacetone CAS 96-26-4 lies in its ability to react with amino acids in the skin’s outer layer (stratum corneum) through a process known as the Maillard reaction. This reaction forms brown pigments called melanoidins, giving the skin a natural tan that lasts 5–7 days. Unlike traditional UV tanning, which can cause severe damage, DHA tanning is non-UV and safe, eliminating risks like photoaging and sunburn.
