Diethylamino Hydroxybenzoyl Hexyl Benzoate（DHHB）-CAS 302776-68-7
Cosmetic-grade DHHB is a high-efficiency organic long-wave UVA sunscreen filter, which is a core premium raw material for high-power broad-spectrum sunscreen products in the global cosmetic industry. Different from ordinary sunscreen ingredients with insufficient long-wave protection, DHHB has strong specific absorption capacity for 320-400nm long-wave UVA, perfectly covering the UVA1 band that causes skin photoaging, sagging and fine lines.
It owns ultra-high molar extinction coefficient, with low dosage achieving high UVA shielding rate and excellent sunscreen efficacy. The product features industry-leading light and thermal stability, no photodegradation or efficacy attenuation under long-term strong ultraviolet radiation, no formula yellowing or discoloration, and effectively solves the problems of sunscreen failure and product color change.
It is mild and skin-friendly, non-irritating and non-sensitizing, with excellent compatibility with various oil-soluble and emulsified sunscreen systems. It can be compounded with UVB sunscreens to form a full-band UVA/UVB protection system, significantly improving SPF and PA values of finished products. Fully compliant with EU, FDA and domestic cosmetic safety standards, it is the preferred key raw material for high-end anti-photoaging and high-power broad-spectrum sunscreen products.
