A definitive link between phthalates and cancer has not been established. Some doctors, however, recommend avoiding phthalates to minimize the risk of developing cancer or reduce the risk of cancer recurrence.
What Are Phthalates?
Phthalates are very prominent chemicals in the lives of American consumers. They help make plastic flexible, extend the life of fragrances, and help prevent nail polish from chipping.
The Problem with Phthalates
Industry groups, such as the American Chemistry Council, say phthalates pose no danger to humans, while environmental groups, such as Greenpeace, consider phthalates a possible carcinogen. The FDA says there is insufficient proof that they're dangerous, so for now, the use of phthalates in cosmetic products is permissible.
Phthalates, though, are banned from all personal care products in Europe, and the National Institute of Health (NIH) and Consumer Product Safety Commission (CPSC) have each expressed concern. For example, the Consumer Product Safety Improvement Act of 2008 prohibits the manufacture or sale of toys containing certain levels of phthalates in the United States.
How to Avoid Phthalates
I don't know if phthalates are dangerous, but the uncertainty of U.S. regulatory agencies with respect to their safety in combination with recommendations from some doctors, such as David Servan-Schreiber, MD, PhD, to avoid them makes me inclined to minimize my exposure.
Avoiding phthalates, however, takes some effort. To minimize exposure, avoid buying/installing vinyl products in your home, such as vinyl tile and shower curtains, and use personal care products that are labeled as "phthalate free."
