1,3-Dihydroxyacetone (DHA) CAS 96-26-4 is a white crystalline powder with a sweet minty odor. Soluble in DMSO and ethanol solutions, DHA is a naturally occurring ketose that is completely biodegradable, edible, and non-toxic to both humans and the environment. It is a highly popular active cosmetic ingredient widely utilized in sunscreens, self-tanning products, and spray cosmetics.
Beyond its sun protection properties, 1,3-Dihydroxyacetone provides excellent moisturizing effects on the skin and is frequently formulated into face creams and hair coloring products. As a safe, highly effective cosmetic raw material, it commands a broad international market, exported extensively to Europe, the United States, the Middle East, and other global regions.
DHA is mainly used as a formula raw material in the cosmetics industry. Especially in sunscreens, it offers special protection, prevents excessive evaporation of skin moisture, and plays a vital role in moisturizing, sun protection, and UV radiation defense.
The ketone functional group in DHA reacts naturally with amino acids and amino groups in skin keratin to form a brown polymer. This simulates a natural-looking tan, giving the skin a healthy, sun-kissed glow without prolonged sun exposure.
DHA serves as a vital intermediate product in glucose metabolism, playing an important role in various physiological and metabolic processes.
