Most people use several different personal care products every day. For example, you may use a shampoo and conditioner, creams or lotions, shaving cream, fragrances, toothpaste and some makeup, including lipstick, eyeliner and eyeshadow.

If you read the labels on these products you'll see a list of chemicals, and you may assume that these chemicals have been tested to make sure that they're safe.

However, the Food and Drug Administration does not do any long-term testing on these chemicals. They may be tested to see whether they result in short-term problems, such as skin irritation, and the FDA may act, if they get complaints about harmful effects from a product.

Several nonprofit groups are finding or conducting the necessary studies and distributing that vital information to us consumers. One organization is the Environmental Working Group (EWG) and in this program, we feature Kaley Beins a senior scientist of chemical safety and toxicology at the EWG.
