    What is it?

    Bronopol is an antimicrobial agent commonly used as a preservative in many types of cosmetics, personal care products and topical medications. It is used as an anti-infective, antimicrobial, fungicide, germicide, bactericide, slimicide and wood preservative. Bronopol is a formaldehyde-releasing preservative (FRP), which is used in place of formaldehyde for people who are sensitive to it.

    Bronopol is an antimicrobial preservative that works by forming formaldehyde in cosmetic products. People exposed to such formaldehyde-releasing ingredients may develop a formaldehyde allergy or an allergy to the ingredient itself. In the U.S. approximately 20% of cosmetics and personal care products contain a formaldehyde-releaser and the frequency of contact allergy to these ingredients is much higher among Americans compared to studies in Europe.
