Abstract
In 2012, the German Commission for the Investigation of Health Hazards of Chemical Compounds in the Work Area re-evaluated the maximum workplace concentration (MAK value) of isopropylbenzene (cumene) [98-82-8]. If the MAK value of 10 ml iso-propylbenzene/m3 (50 mg/m3) is observed, no prenatal toxic effects are to be expected. Therefore, Pregnancy Risk Group C was confirmed. In 2013, the biological tolerance value (BAT value) of 10 mg 2-phenyl-2-propanol (after hydrolysis)/g creatinine was derived in correlation to the MAK value. Pregnancy Risk Group C is also similarly valid for the BAT value. In adherence with the BAT value of 10 mg 2-phenyl-2-propanol (after hydrolysis)/g creatinine, no prenatal toxic effects are to be expected.
