Pentaerythrityl Tetra-Di-T-Butyl Hydroxyhydrocinnamate
What is Pentaerythrityl Tetra-Di-T-Butyl Hydroxyhydrocinnamate?
Pentaerythrityl Tetra-Di-T-Butyl Hydroxyhydrocinnamate is a synthetic compound, specifically a tetraester derived from pentaerythritol and 3,5-di-tert-butyl-4-hydroxyhydrocinnamic acid. It belongs to the class of hindered phenolic antioxidants commonly incorporated into cosmetic formulations, particularly in oil-based products, sunscreens, and fragranced items. In products, it functions by donating hydrogen atoms to neutralize free radicals, thereby interrupting oxidative chain reactions that degrade lipids, essential oils, and volatile compounds. This stabilization mechanism helps preserve the integrity, color, and scent of formulations over time, preventing issues like rancidity or discoloration without directly interacting with skin.
