Parabens

What It Is

A class of widely used synthetic preservatives (methylparaben, ethylparaben, propylparaben, butylparaben) that prevent the growth of bacteria, mould and yeast in cosmetic products. Parabens have been used safely in cosmetics since the 1950s and have excellent safety data. The controversy arose from a 2004 study detecting parabens in breast tumour tissue, but subsequent extensive review by regulatory bodies (EU SCCS, FDA) concluded that parabens in cosmetics at regulated concentrations pose no significant human health risk. The "paraben-free" marketing trend is largely driven by consumer perception rather than scientific evidence.

Key Context

Parabens are among the best-studied and safest preservatives. Alternatives (phenoxyethanol, methylisothiazolinone, essential oils) are not necessarily safer and in some cases have higher rates of sensitisation. For context, naturally occurring parabens are found in blueberries and carrots.
