Where It Comes From
Shampoos, lotions, and other cosmetics; industrial water systems, metalworking fluids, paper/pulp, paints and adhesives [1][2].
How You Are Exposed
Mostly through skin contact with treated products; inhalation of mists or aerosols at work; accidental eye contact with concentrates [1][2].
Why It Matters
Can cause skin sensitization (allergic dermatitis), severe eye irritation, and is very toxic to aquatic life; it can release formaldehyde, a known human carcinogen, though bronopol itself is not classified as a human carcinogen [1][2][3].
Who Is at Risk
Workers handling concentrates; people with existing skin conditions or prior allergy to formaldehyde-releasing preservatives; those frequently using products that stay on the skin [1][2][3].
How to Lower Your Exposure
Check labels for “bronopol” or “2-bromo-2-nitropropane-1,3-diol”; choose products without formaldehyde-releasing preservatives when possible; avoid sprays/mists; follow directions, use in well-ventilated areas; at work, use gloves/eye protection and follow safety protocols [1][2].
