About 4,4'-ISOPROPYLIDENEDIPHENYL/EPICHLOROHYDRIN COPOLYMER DIACRYLATE

A reactive oligomer used in nail cosmetics that contains bisphenol A (BPA) structural units, raising regulatory and safety concerns.

Detailed Analysis

4,4'-Isopropylidenediphenyl/Epichlorohydrin Copolymer Diacrylate is a diacrylate derivative of a bisphenol A-epichlorohydrin epoxy polymer, used as a nail conditioning agent. This ingredient contains the bisphenol A (BPA) structural motif, which has been subject to regulatory scrutiny in the EU due to endocrine disrupting concerns. While not specifically banned in EU Annex II, BPA itself is restricted in cosmetic products (Regulation 1223/2009, Annex III).残餘 monomer content in this oligomer may be of concern. The ingredient is primarily used in professional nail products and is not typically applied to skin.
