Di-n-butyl phthalate. Computer artwork of a molecule of di-n-butyl phthalate (DBP). It has the chemical formula C16.H22.O4. Atoms are represented as spheres and are colour-codded: carbon (grey), hydrogen (blue) and oxygen (red). Phthalates are a group of chemical compounds widely used as plasticisers, substances that soften plastics. Products they are used in include toys and cosmetics. Phthalates do not chemically bind to the plastic and so readily leach out of it. This, with evidence that they may be carcinogenic, disrupt hormones and cause organ damage, led the European Union in June 2005 to ban the use of DBP and other phthalates in toys and childcare articles where their concentration exceeds 0.1% of the mass of the material.
