China Factory Suppliers of Cosmetic Grade 1,3-Dihydroxyacetone (DHA) CAS 96-26-4 for Tanning Products
1,3-Dihydroxyacetone (CAS 96-26-4), commonly known as DHA, features a white crystalline powder appearance with a sweet minty odor. It dissolves smoothly in DMSO and ethanol solutions. As a naturally occurring ketose, DHA is fully biodegradable, edible, and non-toxic to both humans and the environment. It is a highly popular cosmetic ingredient, widely utilized in sunscreens and spray sun protection products.
In addition to sun protection, 1,3-Dihydroxyacetone delivers excellent moisturizing effects on the skin, making it a valuable addition to face creams and hair color formulations. As a safe, reliable, and highly effective cosmetic raw material, DHA enjoys a broad global market, with extensive exports to Europe, the United States, the Middle East, and beyond.
DHA Application
Used primarily in the cosmetics industry, dihydroxyacetone serves as a key raw material. It offers exceptional performance in sunscreens, effectively preventing skin moisture evaporation while providing robust hydration and UV protection.
The ketone functional groups in DHA react naturally with amino acids and amino groups in skin keratin. This reaction forms a brown polymer that simulates a healthy, sun-kissed tan without direct, prolonged sun exposure.
DHA acts as an essential intermediate product in glucose metabolism, playing a highly active and vital role in various physiological metabolic pathways.

Frequently Asked Questions
What is 1,3-Dihydroxyacetone (DHA) CAS 96-26-4?
DHA is a naturally occurring, biodegradable, edible, and non-toxic ketose. It presents as a white crystalline powder with a sweet minty odor and dissolves readily in DMSO and ethanol solutions.
How does DHA function in cosmetic sunscreens?
In cosmetics, DHA serves as a key raw material that helps prevent excessive evaporation of skin moisture. It provides moisturizing benefits, sun protection, and shields against ultraviolet radiation.
How does DHA produce a sunless tan?
The ketone functional group in DHA reacts chemically with the amino acids in skin keratin. This reaction produces a safe, brown-colored polymer that mimics the appearance of a natural sun-exposed tan.
What are the purity and quality specifications of your DHA?
Our DHA features a purity level of 99%. It strictly conforms to rigorous physical, chemical, and microbiological controls, ensuring heavy metals are under 10ppm and common pathogens remain completely negative.
Is DHA safe for the skin and environment?
Yes, DHA is a highly safe, biodegradable, and non-toxic raw material. It is widely exported to demanding markets in Europe, the United States, and the Middle East for use in face creams, sunscreens, and hair coloring products.
