Description of key information

The substance was not inhibiting the microbial activity at concentrations that can be expected in the influent of a sewage treatment plant.

Key value for chemical safety assessment

EC10 or NOEC for microorganisms:
2 mg/L

Additional information

The substance allyl cyclohexylpropionate was not inhibiting to micro-organisms in the study on ready biodegradability at a test concentration of 2 mg/L. This finding is supported by a study on microbial inhibition using Staphylococcus aureus Escherichia coli and other bacterial strains (Morris et al. 1979) and finding no effects at test concentrations of 2 mg/plate applied as 10% (w/v) solutions of the test substance in 95% (v/v) ethanol. In the absence of a test on microbial toxicity, the result of the study on ready biodegradability can be used to derive a NOEC for toxicity to micro-organisms in accordance with ECHA guidance R.7b. The highest test concentration of 2 mg/L applied in the valid study on ready biodegradability was used as the NOEC in the hazard assessment.
