Phthalate Plasticizers in Children's Products

Of the analyzed products, some had two or more phthalate plasticizers, but most products had one phthalate plasticizer. In the early 2000s, diisononyl phthalate (DINP) was the predominant phthalate plasticizer in PVC toys, of which concentration was up to 44%, and di(2-ethylhexyl)phthalate (DEHP) was the second-most dominant [12,13].
