The environmental working group has this to say about cosmetics:

“American families assume personal care products on the market today have been tested by the federal government. Unfortunately, the personal care products industry remains largely unregulated. The FDA does not even require safety testing of ingredients in personal care products before they are used.  While the Food and Drug Administration (FDA) has limited authority to regulate cosmetics, our current laws leave them powerless to screen for chemicals that have been linked to cancer, harm to the reproductive system in both men and women, and severe allergies, among other health effects. The federal law designed to ensure that personal care products are safe has remained largely unchanged since 1938.

These lists of toxic chemicals are constantly updated (see if your shampoo, soap, and so on use any of these chemicals):
