Product Overview
Avobenzone (CAS 70356-09-1) is a leading organic ultraviolet absorber specifically engineered to provide robust protection against the full spectrum of UVA radiation (320–400 nm). As a dibenzoylmethane derivative, it is highly valued in modern cosmetic science for its ability to absorb long-wave UVA rays that penetrate deep into the dermis, contributing significantly to photoaging and skin damage. Its oil-soluble nature ensures seamless integration into a wide range of emulsion-based and anhydrous sunscreen systems.

Industrial Applications
Avobenzone is a critical active ingredient in premium sun care and daily-use skincare products requiring broad-spectrum UV protection. It is commonly formulated alongside photostabilizers such as octocrylene or Tinosorb S to enhance its stability under prolonged sunlight exposure. Beyond sunscreens, it is increasingly incorporated into anti-aging creams, moisturizers, and makeup products with SPF claims. Its regulatory approval by major global agencies—including the U.S. FDA (up to 3%), EU Commission, and ASEAN—makes it a globally compliant choice for international cosmetic brands.
