Description

General description

Dibutyl phthalate (DBP) is most commonly used as a plasticizer in a variety of household products. It has the ability to leach and evaporate into the environment while using or disposing of these products. Therefore, studies are being conducted to assess its toxic and apoptotic effects. Studies have also indicated that exposure to high doses of DBP may interfere with progesterone and estradiol production.

Application

Plasticizer
