Additional information

4,4’-Isopropylidenediphenol, oligomeric reaction products with 1-chloro-2,3-epoxypropane, reaction products with butan-1-ol and 3-aminomethyl-3,5,5-trimethylcyclohexylamine was not toxic to waste water (activated sludge) bacteria at or below a loading rate of 32 mg/l (NOEC).
