Applicant's summary and conclusion

Conclusions:
Applying read-across based on grouping of substances (category approach), no potential to induce gene mutation in bacteria with and without metabolic activation is predicted for the target substance.
Executive summary:

The available data on gene mutation in bacteria in the Alcohol Ethoxylates (AE) category indicate no potential for the target substance to exhibit any mutagenic activity. As explained in the category justification, the differences in molecular structure and composition between the target substance and the members of the AE category are unlikely to lead to differences in the mutagenic potential.
