Conclusion on classification

According to Annex VI of Directive 67/548/EEC, the reaction mass of phenol and 4,4'-isopropylidenediphenol is classified as R50/53 “very toxic to aquatic organisms” and “may cause long term adverse effects in the aquatic environment” since the lowest acute EC50 value was 1 mg/L for one of the major components, 4,4'-isopropylidenediphenol, and several minor components of the reaction mass are not readily biodegradable. According to GHS, the reaction mass of phenol and 4,4'-isopropylidenediphenol is classified as Category Acute 1, based on acute toxicities of 1 mg/L and Category Chronic 2 based on chronic toxicity data (NOEC values) reported for phenol and Bisphenol A that are in the range of 0.016 - 0.05 mg/L.
