 Chlorinated Paraffins (CAS NO.108171-27-3) was used as plasticizers for polyvinyl chloride, as extreme-pressure additives in metal-machining fluids, as additives to paints, coatings and sealants to improve their resistance to chemicals and to water, and as flame retardants for plastics, fabrics, paints and coatings. No data on occupational exposure levels were available. Chlorinated paraffins have been detected in water and sediments, in tissues of marine animals, in human foods and in human tissues post mortem.

Suspected carcinogen with experimental carcinogenic and neoplastigenic data. A combustible liquid. When heated to decomposition it emits acrid smoke and irritating fumes.

Chlorinated Paraffins (CAS NO.108171-27-3) are mixtures of polychlorinated n-alkanes produced by the reaction of chlorine with specific normal paraffin fractions from petroleum distillation. Carbon-chain lengths of commercial products are generally between C₁₀ and C₃₀, and the chlorine content is typically between 40 and 70%.
