Benzyl butyl phthalate (BBP) is an organic compound historically used a plasticizer, but which has now been largely phased out due to health concerns. It is a phthalate ester of containing benzyl alcohol, and n-butanol tail groups. Like most phthalates, BBP is non-volatile and remains liquid over a wide range of temperatures. It was mostly used as a plasticizer for PVC, but was also a common plasticizer for PVCA and PVB.

BBP was commonly used as a plasticizer for vinyl foams, which are often used as sheet vinyl flooring and tiles. Compared to other phthalates it was less volatile than dibutyl phthalate and imparted better low temperature flexibility than di(2-ethylhexyl) phthalate.^[2]

BBP is classified as toxic by the European Chemical Bureau (ECB) and hence its use in Europe has declined rapidly.
