Avobenzone Powder

Product Overview

Avobenzone Powder | CAS 70356-09-1 Cosmetic UVA UV Filter

Avobenzone Powder (CAS 70356-09-1, INCI: Butyl Methoxydibenzoylmethane) serves as a benchmark oil-soluble UVA filter for cosmetic sun care formulas. It absorbs long-wave UVA light from 320 nm to 400 nm, the main trigger for skin photoaging, dark spots and collagen breakdown. This pale yellow crystalline powder mixes smoothly into oil phases of emulsions. Formulators commonly pair it with photostabilizers and UVB filters to build reliable broad-spectrum SPF products.
