Parabens are commonly used as preservatives in personal care products, topical pharmaceuticals, and, sparingly, as a food additive. Parabens are easy to identify by looking at a package's ingredients list for words that include "paraben", such as methylparaben, propylparaben, or butylparaben. Several parabens are often used in combination and/or with additional preservatives to protect products from microbial growth.
You can find parabens in most shampoos, conditioners, cosmetics, shaving products, personal lubricants, and countless other personal care products.
Parabens have been shown to be readily absorbed by the skin, then metabolized and excreted by the body. Parabens are not known to bioaccumulate in the body, according to the Environmental Working Group's Skin Deep Database.
