Description and Uses
Diethyl phthalate (DEP) is a member of the group of esters of phthalic acid known as phthalates, used ubiquitously as solvents and plasticisers worldwide. DEP can increases the flexibility of plastics. It is also contained in deodorant formulations, perfumes, emollients and insect repellents. It can cross react with dimethyl phtalate.
Diethyl phthalate is a Plasticizer for cellulose ester plastic films and sheets; in molded plastics; manufacturing varnishes; cosmetics.
