Chlorinated paraffin is a family of industrial chemicals produced by adding chlorine to paraffin wax. These waxy solids are valued for their flame retardant properties, making them widely used in plastics, rubber, textiles, and cable insulation. They are categorized into short-chain, medium-chain, and long-chain types, each with varying chlorine content and applications. Chlorinated paraffins provide enhanced fire safety in various products, but their environmental persistence and potential toxicity are subjects of regulatory concern.
