Bronopol allergic contact dermatitis

Contact Dermatitis, 1983
Bronopol (2‐bromo‐2‐nitropropane‐1, 3‐diol) is an antimicrobial widely used as a preservative, primarily in cosmetic formulations. Analysis of patch tests performed on our patients revealed an incidence of 12.5% relevant positive results to 0.5% and/or 0.25% bronopol.

Contact allergy to Bronopol

Contact Dermatitis, 1990
A total of 8149 patients were patch tested with the preservative Bronopol in 7 European contact clinics. The Majority of patients (6507) were investigated in London. Reactivity was low, with a total of 10 irritant (0.12%) and 38 allergic reactions (0.47%).

Effects of different bronopol treatments on final survival rates in the artificial incubation of crayfish eggs (Pacifastacus leniusculus, Astacidae)

Aquaculture Research, 2013
Two experiments were conducted on the effects of bronopol in the artificial incubation of crayfish eggs (Pacifastacus leniusculus) with the aim to search an alternative to formaldehyde. In the first experiment, 50, 250, 500 and 1000 ppm bronopol and 3000

Rapid ultraviolet spectrophotometric determination of bronopol: application to raw material analysis and kinetic studies of bronopol degradation

Journal of Pharmaceutical and Biomedical Analysis, 1996
A simple and rapid spectrophotometric assay is described for bronopol determination in raw material. The method is based on the measurement of absorbance (at 244 nm) of bromonitroethanol (sodium salt of aci-form), the chromophoric derivative formed from bronopol instantaneously by a retroaldol reaction in the presence of 0.1 M NaOH. This derivative has
