Phthalates started to be used in 1920 as a replacement of camphor used in the manufacture of plastics. The main use of phthalates is as plasticizers: substances added to plastics to increase their durability. They can be found in personal care products such as perfume, eye-shadow, nail polish and hair spray. Phthalates are insoluble in water, soluble in oil and they have a syrupy liquid consistency. In USA, EU and Canada, phthalates are eliminated from many products because of health concerns. The average price of phthalate is 73 cents/lb.
