Facts to Drive Phthalate-free Plasticizer Development

Biology of the Neonate November, 2000; 78; 269-276

Reproductive Toxicology 2000 Nov 1; 14: 513-532

Health Issue of Phthalate Plasticizers:

Endocrine disruptor, cause of genetic disorders, abnormalities in physiological development etc

Around 1998, European Union (EU) banned phthalates from toys intended for children under 3 years of

age (Lancet, Dec 11, 1999)

In October 2007, US passed a law, prohibiting the manufacture, sale and distribution of Phthalate

Plasticizer in medical and child care product at conc. higher than 0.1 percent

Phthalate-free articles are mandatory for medical devices, toys & child-care articles and food packaging
