About
A highly reactive and hazardous chemical intermediate — not used as-is in cosmetics but may appear as a trace processing reagent.
Benzoyl Chloride (CAS 98-88-4) is an acyl chloride (C6H5COCl) that reacts violently with water, alcohols, and bases, releasing HCl gas and benzoic acid. It is primarily used as an intermediate in pharmaceutical and chemical synthesis (producing peroxides, dyes, resins). Its GHS classification includes skin corrosion (H314), serious eye damage (H318), and acute toxicity. It is not intentionally added to finished cosmetic products; any presence would be trace residual from manufacturing. Its listing in CosIng likely reflects its role as a processing chemical rather than an ingredient.
