Tetradibutyl Pentaerithrityl Hydroxyhydrocinnamate
What is Tetradibutyl Pentaerithrityl Hydroxyhydrocinnamate?
Tetradibutyl pentaerithrityl hydroxyhydrocinnamate is a synthetic hindered phenolic antioxidant, chemically structured as a pentaerythritol core esterified with four units of 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionic acid. Developed for industrial and cosmetic applications, it functions by scavenging free radicals and interrupting oxidative chain reactions in lipid-rich environments. In skincare products such as creams, lotions, lip products, and foundations, it protects oils, emollients, fragrances, and light-sensitive colorants from degradation caused by air, light, or heat exposure. This stabilization maintains product texture, scent, and appearance throughout shelf life, ensuring consistent performance without altering sensory qualities.
