What is a Paraben?and why is it in your cosmetics?

Parabens are actually several distinct chemicals with a similar molecular structure. Four of these are used frequently in cosmetics: ethylparaben, butylparaben, methylparaben and propylparaben. Methylparaben and propylparaben are the most common of these. Parabens are most common in personal care products that contain significant amounts of water, such as shampoos, conditioners, lotions and facial and shower cleansers and scrubs, in order to discourage the growth of microbes. While Cosmetic Ingredient Review recommends concentration limits for single and total paraben concentration in a single product, these recommendations do not account for exposure to parabens from several products by a single individual [6]. A 2004 UK study detected traces of five parabens in the breast tumors of 19 out of 20 women studied [7]. This small study does not prove a causal relationship between parabens and breast cancer, but it is important because it detected the presence of intact parabens—unaltered by the body’s metabolism—which is an indication of the chemical’s ability to penetrate skin and remain in breast tissue. A more recent study found higher levels of one paraben, n-propylparaben, in the axilla quadrant of the breast (the area nearest the underarm) [8]. This is the region in which the highest proportion of breast tumors are found, although paraben concentration in the tissue samples was not related to location of breast tumors in individual women.
