Abstract
In 2018, the German Commission for the Investigation of Health Hazards of Chemical Compounds in the Work Area re-evaluated and confirmed the maximum workplace concentration (MAK value) of 2-propanol [67-63-0]. If the MAK value of 200 ml 2‑propanol/m3 (500 mg/m3) is observed, no prenatal toxic effects are to be expected. Therefore, Pregnancy Risk Group C was likewise confirmed. In 2010, biological tolerance values (BAT values) of 25 mg acetone/l blood and 25 mg acetone/l urine were derived in correlation to the MAK value. Pregnancy Risk Group C is therefore similarly valid for the BAT value. In adherence with the BAT values of 25 mg acetone/l blood and 25 mg acetone/l urine, no prenatal toxic effects are to be expected.
