Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Applicant's summary and conclusion

Interpretation of results:
other: Skin irrit. 2, H315. Classification according to Regulation (EC) No. 1272/2008 (CLP/EU GHS).
Conclusions:
Applying read-across based on grouping of substances (category approach), an irritating potential is predicted for the target substance.
Executive summary:

The available data on skin irritation / corrosion in the Alkyl Ether Sulfates (AES) category indicate a skin irritation potential 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 skin irritation / corrosion potential.
