Description and Uses
Bronopol, a formaldehyde releaser, was reported as an allergen in dairy workers. In a recent case report, bronopol was contained in a lubricant jelly used for ultrasound examination and caused contact dermatitis in a veterinary surgeon.
First synthesized in 1897, bronopol was primarily used as an effective preservative agent and possesses a wide spectrum of antibacterial activity and inhibits the growth of fungi and yeasts. It can be used in the formulation of a wide variety of cosmetic and personal care products, especially in leave-on and rinse-off shampoos, creams, lotions, rinses and eye makeup to protect the product integrity by preventing or slowing bacterial growth.
Bronopol is used as a microbiocide/microbiostat in oil field systems, air washer systems, air conditioning/humidifying systems, cooling water systems, papermills, absorbent clays, metal working fluids, printing inks, paints, adhesives and consumer/institutional products. A formulating technical material is also registered.
