Description of key information

The testing of toxicity to soil macroorganisms except arthopods was waived.

Key value for chemical safety assessment

Additional information

Waiving was done according to ANNEX IX column 2 of the REACH regulation. Soil represents no target compartment and sodium methanolate is expected to have a low potential of toxicity to soil macroorganisms.
Further, studies on methanol and potassium hydroxide support these considerations, indicating the low level of terrestrial toxicity: In an acute filter paper test on Eisenia fetida methanol revealed mortality effects with an LC50(48h) value of >=1 mg/cm² (Roberts & Dorough, 1984).
As read-across from potassium hydroxide, a 90-day EC50 value of 850 mg/L (artificial soil) for Enchytraeus sp. (> 95 % Cogentia sphagnetorium) was reported (Heungens, 1984).
