Additional information
Specific situation concerning methanol:
Skin:
The irritation potential of an unspecified dose of undiluted methanol in rabbits was examined under occlusive conditions after exposure intervals of 1, 5, and 15 minutes and 20 hours. According to Draize scoring, no signs of skin irritation were observed 24 hours and 8 days after treatment for any of the exposure time periods (BASF, 1975).
Eye:
One hour after instillation of 0.05 mL undiluted methanol into the eyes of two rabbits, slight erythemas and corneal opacity as well as moderate edemas associated with secretion were observed. After 24 hours, the effects were assessed as mild, and after 8 days the animals had no symptoms (BASF, 1975).
In another study, mild to moderate conjunctivitis and edemas as well as mild iritis were produced in six rabbits after instillation of 0.1 mL undiluted methanol into the eyes. Average scores after 24, 48, and 72 hours were approximately 2 for conjunctivae and < 1 for other effects. Primary irritation subsided after 72 hours, although redness of the conjunctivae persisted at that time. Information on effects after 8 and 14 days was not available (Jacobs, 1990).
Exposure of rats to an atmosphere saturated by methanol vapours at 20 °C produced severe irritation of mucous membranes and milky corneal opacity (time not specified) and eventually led to mortality of all animals within 8 hours (BASF, 1975). This was an additional observation and is not applicable for evaluation of irritant effects. Therefore, it is not relevant for classification.
Due to the very small concentration of the substance is considered as non irritating/non corrosive.
Justification for classification or non-classification
Due to the typical concentration of methanol in the registered substance it is not classified as corrosive.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
