Environmental groups claim some children's bath products contain a suspected cancer-causing chemical in amounts that reach or exceed safe limits. The chemical in question -- 1,4-dioxane -- is found in products made by companies such as Johnson and Johnson, Disney, Kimberly-Clark, and Gerber, says David Steinman, head of the environmental publishing company Freedom Press.

The Environmental Protection Agency (EPA) calls this chemical, already known to cause cancer in animals, a probable human carcinogen. But there is no real regulation on the petroleum-derived chemical and the Food and Drug Administration (FDA) only recommends cosmetic companies limit the concentration of 1,4-dioxane to 10 parts per million (ppm).

Studies show Johnson's Kids Shampoo Watermelon Explosion contains the maximum recommended level of 10 ppm. They also reveal that Kid Care's Hello Kitty Bubble Bath contains 12.3 ppm of the chemical. And two adult shampoos have been found to have twice the recommended level of this chemical that is typically a manufacturing by-product.

It's been reported that nearly 57 percent of all baby soaps contain 1,4-dioxane. But Iris Grossman, director of communications at Johnson and Johnson, stresses that all of her products are within FDA limits.

Cancer is not the only risky link to children's bath products. It seems these items are also linked to early puberty development. And this is concerning because a fast-paced growth rate combined with children's porous skin increases susceptibility to toxins that can enter the bloodstream. One breast cancer expert says an increase in breast cancer risk is linked to toxic exposures during the formative years of life.

Parents want what is best for baby. No parent wants to expose their baby to cancer-causing chemicals. Because you cannot always rely on baby care product makers to offer only the safest and the best products for your baby, the Environmental Working Group offers Skin Deep, an online searchable safety ratings database of brand-by-brand baby care products.

Skin Deep's database of baby care product categories includes: after sun products; anti-itch/rash creams; baby bubble baths; baby lotions; baby oils; baby powders; baby shampoos; baby soaps; baby sunscreens; baby toothpastes; baby wipes; cradle cap treatments; diaper creams; lip balm/treatments; and nipple cream for mothers.

While every baby care product on the market is not yet included in the Skin Deep baby care products database, parents can find many of the major brands listed. Each product comes complete with a safety score that allows parents to shop wisely.

Of special note: Parents can be safe from cancer-causing personal care products too. Back in February, we featured Skin Deep's Campaign for Safe Cosmetics when it launched a searchable database of adult personal care products used every day that might contain chemicals linked to cancer, birth defects and other serious health issues.

Dr. Samuel Epstein hasn't made many friends in the Canadian and American Cancer Societies or with the federal government because he has been a publicly vocal critic to what he believes is their complete lack of attention to the every day cancer risks that each of us encounter in life. His criticism is justified.

Dr. Epstein, who teaches environmental and occupational medicine at the University of Illinois, wants us to know that we are exposed to cancer-causing chemicals when we shampoo our hair, put on makeup, tidy the house, control garden pests, in how we store our food -- and in the food we eat.
