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), a dermal LD50 > 2000 mg/kg bw is predicted for the target substance.
Executive summary:

The available data on acute dermal toxicity in the Alkyl Ether Sulfates (AES) category reveal a dermal LD50 value > 2000 mg/kg bw. Based on the category approach, a dermal LD50 value > 2000 mg/kg bw is predicted 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 AES category are unlikely to lead to differences in the toxicological properties with respect to acute dermal toxicity.
