    The principal phthalate esters used in cosmetic products are dibutyl phthalate DBP, dimethyl phthalate DMP and diethyl phthalate DEP. They are used primarily as plasticizers in products such as nail polishes to reduce cracking by making them less brittle, hair sprays to help avoid stiffness by allowing them to form a flexible film on the hair.
