Additional information

Bronopol is slowly degraded in air by photochemical processes (half-life = 12.106 d). In water, bronopol is photodegraded at environmentally relevant temperatures with a half-life of 24.3 h.

In water and at environmental relevant pH values, hydrolysis of bronopol takes place very rapidly with a significant pH and concentration dependency displaying an accelerated rate of hydrolysis at lower concentrations and elevated pH.
