Additional information

Phototransformation in air:

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.

Hydrolysis:

Based on the molecular structure of Bisphenol A, hydrolysis is not expected under environmentally relevant conditions.

Phototransformation in water:

Bisphenol A has a half-life of 0.5 to 10 days for direct photolysis and 0.7 to 1.3 days for indirect photolysis.
