Description of key information

After exposure to air, Bisphenol A will be rapidly degraded by photochemical processes. The rate constant for indirect photolysis in air (OH-mediated photodegradation) is 80.6E-12 cm3 / (molecule*sec) and half-life is 0.13 days, assuming 12 hours daylight and a hydroxyl radical concentration of 1.5E6 molecules per cm3.

Key value for chemical safety assessment

Half-life in air:
0.13 d
