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.
Legislative control 
European Union 
The use of DBP has been restricted in the European Union for use in children's toys since 1999.
United States 
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 and childcare articles, in concentrations of 1000 ppm or greater, under section 108 of the Consumer Product Safety Improvement Act of 2008 (CPSIA).
DBP is produced by the reaction of n-butanol with phthalic anhydride. It is produced domestically by Eastman Chemical Company, but they have announced that they will end production and exit the DBP and DEP (diethyl phthalate) market in December 2011.
With the exodus of all domestic producers the nearest supply option for DBP for U.S. customers is Miami Chemical which imports material from their manufacturing partners located in South America.
Based on urine samples from people of different ages, the European Commission Scientific Committee on Health and Environmental Risks (SCHER) concluded that total exposures to individual phthalates in the general population are below tolerable daily intakes (TDI), except in the case of DBP for which efforts to further reduce exposures are needed.
