Additional information
Conclusion on classification
Classification and labelling according to DSD (67/548/EEC)
Justification for classification or non classification
Three acute tests have been performed with fish, daphnia and algae. EC50-values were in the range of 1-10 mg/l. m-Cresol is readily biodegradable. Therefore, a classification related to risk phrases R50, 51, 52, 53 or combined risk phrases is not required.
Classification and labelling according to CLP (EC 1208/2008)
Justification for classification or non classification
m-Cresol is readily biodegradable. Three acute tests have been performed with fish, daphnia and algae. EC50-values were in the range of 1-10 mg/l. There is a chronic test with daphnia available, yielding a NOEC of 1 mg/L. According to 2nd ATP, a classification “chronic cat. 3, H412” is required.
