3928 Monobutylphthalate Monobutyl phthalate (MBP), is an active metabolite of di-n-butyl phthalate (DBP). Dibutyl phthalate (DBP) is a commonly used plasticizer. It is also used as an additive to adhesives or printing inks. It is soluble in various organic solvents, e.g. in alcohol, ether and benzene. DBP is also used as an ectoparasiticide.. DBP was added to the California Proposition 65 (1986) list of suspected teratogens in November 2006. It is a suspected endocrine disruptor. It was used in some nail polishes; all major producers began eliminating this chemical from nail polishes in the Fall of 2006. DBP was permanently banned in children's toys, Monobutyl phthalate inhibits steroidogenesis by downregulating steroidogenic acute regulatory protein expression. 131-70-4 8575 C12H14O4 222.24 White powder. 73.5°C No indication of carcinogenicity to humans (not listed by IARC).
