Science
Mechanism of Action
As a light stabilizer, PEG-6 SESQUI(BENZOTRIAZOLYL T-BUTYL HYDROXYPHENYLPROPIONATE) integrates into cosmetic formulations to absorb and dissipate harmful light radiation, thereby preventing product ingredient degradation. Furthermore, it is a precursor in the condensation polymerization of Polyester-39, contributing to the creation of a film-forming agent that defends against external stressors such as UV radiation, pollution, and chemical exposure on biological surfaces like skin and hair.
