Diethylamino hydroxybenzoyl hexyl benzoate

Diethylamino hydroxybenzoyl hexyl benzoate (CAS 302776-68-7 ), widely recognized in the industry by its abbreviation DHHB, is an oil-soluble UVA filter used in sunscreen and cosmetic formulations. It delivers broad-spectrum UVA absorption, targeting the 320–400 nm range, and is valued for its photostability and compatibility with other UV filters. In suncare formulations, DHHB is used as a primary UVA filter. It helps meet regulatory SPF and UVA protection requirements in leave-on products such as sunscreens, day creams, and foundations. Its oil solubility makes it suitable for anhydrous and emulsion systems. In plastics and polymer applications, it functions as a light stabilizer to prevent UV-induced degradation in films, coatings, and molded parts. This ensures long-term durability for industrial materials. Coatings and adhesive formulators incorporate it to extend the service life of UV-sensitive substrates exposed to outdoor weathering. This prevents yellowing and structural failure in various applications. The product is supplied as a pale yellow to yellow powder or as a solution pre-dispersed in cosmetic-grade emollients for easier incorporation. It is available in cosmetic-grade purity, typically at ≥98%. It meets requirements for use in regulated personal care markets including the EU, where it is approved under Annex VI of the Cosmetics Regulation. This ensures safety and compliance for global manufacturers. Contact us for supply of Diethylamino hydroxybenzoyl hexyl benzoate Request Quote
