||N-methyl-2-pyrrolidone (methylpyrrolidinone, NMP) is an industrial solvent. It can be absorbed through the skin. The substance is not mutagenic, genotoxic or carcinogenic but it is embryotoxic, foetotoxic and teratogenic at doses which are non-toxic to the mothers. On the basis that it disturbs prenatal development in more than one animal species, in the Scandinavian countries NMP has been classified in the IB group, which comprises substances probably harmful to human reproduction. Based on the NOAEL value obtained in an experimental study (500 mg/m3) and appropriate uncertainty factors, a TLV of 120 mg/m3 and a short-term exposure level of 240 mg/m3 have been proposed. In addition, notations are suggested for irritation, foetotoxicity and skin absorption.
