Chlorinated paraffin acts as a plasticizer as well as a flame retardant. Avoids embitterment of films. It is chemically inert and non-corrosive, practically non-volatile, non-flammable and imparts flame-resistant properties. Shows excellent resistance to water and decomposes before boiling. It is insoluble in water and glycerine, soluble in many organic solvents, slightly soluble in aromatic hydrocarbons, aliphatic hydrocarbons, ketones, esters, vegetable and animal oils and miscible with benzene, chloroform, ether, carbon tetrachloride. With viscosity ranging from 10-20 poises, it is also used in the preparation of mastics and emulsion paints.
