Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

The acute toxicity of alcohol ethoxysulfates has been extensively evaluated in numerous oral and dermal toxicity studies. Therefore this endpoint is covered by read across from structurally related AES. The AES reported within the AES category show similar structural, physico-chemical, environmental and toxicological properties. The approach of grouping different AES for the evaluation of their effects on human health and the environment was also made by the Danish EPA (2001) and HERA (2003), supporting the read across approach between structurally related AES. For details please refer to the category justification attached in IUCLID section 13.

The oral LD50 values based on the test material were all at least above 2 g/kg and the same result was achieved for the dermal route when tested.

Acute toxicity by inhalation was not tested as according to REGULATION (EC) No 1907/2006, Annex VIII, Section 8.5, Column 2.

In summary, no classification is warranted for either route of acute toxicity.

The following information is taken into account for any hazard / risk assessment:

Many high quality studies investigating the acute toxicity of alcohol ethoxysulfates (AESs) have shown that in terms of acute toxicity the use of these compounds are of low concern. They are of low oral and dermal toxicity.

Justification for selection of acute toxicity – oral endpoint
The reliable OECD Guideline study which resulted in the LD50 was chosen.

Justification for selection of acute toxicity – dermal endpoint
Reliable OECD guideline study.

Justification for classification or non-classification

Classification criteria according to 67/548/EEC and (EC) 1272/2008 are not fulfilled.
