Applicant's summary and conclusion

Interpretation of results:
other: CLP/EU GHS criteria not met, no classification required according to Regulation (EC) No 1272/2008
Conclusions:
Applying read-across based on grouping of substances (category approach), an oral LD50 (rat, m/f) > 2000 mg/kg bw is predicted for the target substance.
Executive summary:

The available data on acute oral toxicity in the 'linear' subgroup of the Alcohol Ethoxylates (AE) category reveal an oral LD50 value > 2000 mg/kg bw indicating only low hazardous properties of the linear AE substances after acute exposure. Based on the category approach, an oral LD50 value > 2000 mg/kg bw is considered for the target substance. As explained in the category justification, the differences in molecular structure and composition between the target substance and the members of the 'linear' subgroup of the AE category are unlikely to lead to differences in the toxicological properties with respect to acute oral toxicity.
