Octadecyl Di-T-Butyl-4-Hydroxyhydrocinnamate
What is Octadecyl Di-T-Butyl-4-Hydroxyhydrocinnamate?
Octadecyl Di-T-Butyl-4-Hydroxyhydrocinnamate is a synthetic hindered phenolic antioxidant, chemically known as the stearyl ester of 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoic acid. Originally developed for polymer stabilization, it serves in cosmetics as a formulation protector within categories like creams, lotions, and oils. It works by scavenging free radicals and interrupting oxidative chain reactions, donating a hydrogen atom to neutralize peroxides and prevent lipid peroxidation. This action safeguards unsaturated oils, emollients, fragrances, and light-sensitive components from breakdown, avoiding rancidity, odor development, and color shifts. By preserving ingredient integrity, it ensures consistent product performance over time. Though primarily for stability, it minimizes user exposure to potentially irritating oxidized byproducts during application.
