Key value for chemical safety assessment

Additional information

The potential of the test material to cause toxic effects to microorganisms was investigated in an activated sludge respiration inhibition test conducted in accordance with the standardised guideline OECD 209 under GLP conditions. The EC50 for the test material was greater than 10000 mg/L. The NOAEC value was determined to be 1000 mg/L. As per the CSA, it is modelled that there is negligible exposure to soil.  Any exposure is considered to have a RCR < 0.01 therefore is considered not to be of any concern. Exposure to the registered substance is considered to be minimal based on the low concentration of the substance in the formulated and finished products. It is therefore considered that further testing is not justified.
