TETRABUTYL ETHYLIDENEBISPHENOL
Description
Tetrabutyl ethylidenebisphenol (TBEP) is a synthetic organic compound widely used in the cosmetics and personal care industry. This ingredient functions primarily as an antioxidant and UV stabilizer in various skincare formulations. TBEP's molecular structure consists of two phenol rings connected by an ethylidene bridge, with four butyl groups attached.
In skincare products, TBEP helps protect other ingredients from degradation caused by exposure to light and air. This preservation effect extends the shelf life of formulations and maintains their efficacy over time. Additionally, TBEP exhibits mild antioxidant properties, potentially offering some protection against free radical damage to the skin.
The ingredient is typically used in low concentrations, ranging from 0.01% to 0.1% in most formulations. TBEP is oil-soluble, making it compatible with a wide range of cosmetic bases, including creams, lotions, and oil-based serums. While generally considered safe for topical use, some individuals may experience sensitivity. As with any skincare ingredient, patch testing is recommended before widespread application, especially for those with sensitive skin or a history of allergic reactions to cosmetic products.
