Benzylbutylphthalate (BBzP), also called n-butyl benzyl phthalate (BBP) or benzyl butyl phthalate, is a phthalate, an ester of phthalic acid, benzyl alcohol and n-butanol. It comes under trade names eg. Palatinol BB, Unimoll BB, or Sicol 160. It is mostly used as a plasticizer for PVC. It is considered a toxicant.
BBzP is commonly used as a plasticizer for vinyl foams, which are often used as floor tiles. Other uses are in traffic cones, food conveyor belts, and artificial leather.
BBP is classified as toxic by the European Chemical Bureau (ECB) and hence its use has declined rapidly in the last decade. There are only two producers remaining in the EU.
