4,4'-ISOPROPYLIDENEDIPHENOL/EPICHLOROHYDRIN COPOLYMER

Description

4,4'-Isopropylidenediphenol/epichlorohydrin copolymer, commonly known as bisphenol A diglycidyl ether (BADGE), is a synthetic resin widely used in cosmetic and skincare formulations. This ingredient is primarily employed as a film-forming agent and viscosity regulator in various products, including moisturizers, sunscreens, and makeup.

The copolymer is formed through the reaction of bisphenol A and epichlorohydrin, resulting in a compound with excellent adhesive properties and chemical resistance. Its molecular structure allows it to create a protective barrier on the skin, helping to lock in moisture and shield against environmental stressors.

In skincare applications, this ingredient enhances product stability and improves texture, contributing to a smooth, even application. It also aids in the uniform dispersion of other active ingredients throughout the formulation. While generally considered safe for topical use, some concerns exist regarding potential estrogenic activity and allergenicity in sensitive individuals.

Formulators must adhere to regulatory guidelines regarding concentration limits to ensure product safety. When properly utilized, 4,4'-isopropylidenediphenol/epichlorohydrin copolymer can significantly enhance the performance and sensory attributes of skincare products, making it a valuable ingredient in cosmetic chemistry.
