Phthalates are synthetic chemicals that are added to hard plastics to make them soft and malleable. Phthalates can be found in everyday consumer products such as carpets, paints, glues, wall coverings, tablecloths, furniture upholstery, shower curtains, garden� hoses, toys, shoes, automobile upholstery, food packaging and medical products. Exposure to phthalates has been linked to respiratory health problems, asthma and allergies in infants and children, and changes in reproductive system development in baby boys. The National Toxicology Program classifies a commonly used phthalate, called di(2-ethylhexyl) phthalate or DEHP, as "reasonably anticipated to be a human carcinogen."
