POLY(BENZOTRIAZOLYLHYDROXYPHENETHYL METHACRYLATE)

Description

Poly(benzotriazolylhydroxyphenethyl methacrylate) is a sophisticated UV filter widely used in sunscreen formulations and cosmetic products. This synthetic polymer belongs to the class of organic UV absorbers and provides broad-spectrum protection against both UVA and UVB radiation. Its molecular structure consists of a methacrylate backbone with pendant benzotriazole groups, which effectively absorb and dissipate harmful UV rays.

The compound exhibits excellent photostability, maintaining its protective properties even after prolonged sun exposure. It is particularly valued for its ability to integrate seamlessly into various cosmetic formulations without causing significant alterations to the product's texture or appearance. Poly(benzotriazolylhydroxyphenethyl methacrylate) is oil-soluble, making it compatible with a wide range of cosmetic ingredients and bases.

This UV filter has demonstrated low skin penetration, reducing the risk of systemic absorption and potential adverse effects. Its efficacy in preventing UV-induced skin damage, including photoaging and oxidative stress, has been documented in multiple studies. The ingredient is approved for use in sunscreens by regulatory bodies in many countries, including the FDA in the United States and the European Commission in the EU, with specific concentration limits to ensure safety and effectiveness.
