Dibutyl phthalate
Dibutyl phthalate ( DBP) is an organic compound which is commonly used as a plasticizer because of its low toxicity and wide liquid range. With the chemical formula C 6 H 4 (CO 2 C 4 H 9) 2, it is a colorless oil, although commercial samples are often yellow. [3] Production and use [ edit]

Di-n-butyl Phthalate (DBP) - Proposition 65 Warnings Website
DBP is on the Proposition 65 list because it can cause birth defects or other reproductive harm. Exposure to DBP during pregnancy may affect development of the child, and may also harm the male and female reproductive systems. Proposition 65 requires businesses to determine if they must provide a warning about exposure to listed chemicals.
