Description of key information

In a test for Nitrification Inhibition using Nitrosomonas spp., Alcohols, C11-14-iso, C13-rich exhibited no inhibition at the highest nominal concentration tested. This resulted in a 4-hour NOELR (No Observed Effect Loading) of 105.3 mg/l, based on nitrification rate.

Key value for chemical safety assessment

Additional information

There is additional evidence based on ready biodegradation test results to indicate that the substance will not be toxic to microorganisms at a concentration expected in the influent of a sewage treatment plant.
