Butyl benzyl phthalate (BBP), also referred to as 1,2 benzenedicarboxylic acid, butyl phenylmethyl ester, and benzyl n-butylphthalate, is a clear, oily liquid at room temperature. BBP is formed from the reaction of the monobutyl ester of phthalic acid with benzyl chloride and butanol.
The main uses of BBP are as a plasticizer for vinyl flooring, vinyl foams, and carpet backing. Other products which are plasticized with BBP are cellulose plastics, polyvinyl acetate, polysulfides, and polyurethane. More specifically, BBP is used as a plasticizer in polyvinyl chloride used to make food conveyer belts, carpet tiles, artifical leather, tarps, automotive trim, weather stripping, traffic cones, and to a limited amount in production of vinyl gloves. BBP is also used in some adhesives.
BBP is released to the environment during its production and when used as a plasticizing agent. In addition, use and disposal of products plasticized with BBP may lead to exposures.
The reassessment will present reference values for the noncancer effects of BBP (RfD and RfC), where supported by available data, and a cancer assessment. The assessment will be subject to internal and external peer review along with Agency review. The final product will reflect the Agency opinion on the toxicity of BBP.
