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, Sicol 160, or Santicizer 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.
The Canadian House of Commons has passed a Private Member's Bill, Bill C-307, that will require a reassessment of benzyl butyl phthalate by the Minister of Health and the Minister of Environment. As of January, 2008, it still requires Senate approval. In 2008 four sellers of BBP were sanctioned by the Belgian Competition Council for participating in a cartel.[1]
