Additional information

The genetic toxicity of alcohol ethoxysulfates (AES) was evaluated in several in vitro and in vivo genotoxicity tests. 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.

Studies which were undertaken in vitro using a number of test systems have resulted in negative findings. The Ames tests conducted with AES (C12-14, 1-2.5 EO) Na (CAS 68891-38-3) u

sing strains of S. typhimurium showed negative results. Testing for mammalian genotoxicity with AES (C12-14, 1-2.5 EO) Na (CAS 68891-38-3) revealed a negative outcome as well. The result of in vivo testing revealed that the substance AES (C12-14, 1-2.5 EO) Na (CAS 68891-38-3) has no clastogenic potential. According to the Regulation EC No. 1907/2006 (REACH) VIII 8.4.2, column 2, an in vitro cytogenicity study in mammalian cells does not need to be conducted if adequate data from an in vivo cytogenicity test are available. 

Based on the outcome of these tests also AES (C12-13, 1-2.5 EO) Na (CAS 161074-79-9) can be considered as non-genotoxic.

Justification for classification or non-classification

The available data on genetic toxicity do not meet the criteria for classification according to Regulation (EC) No. 1272/2008, and are therefore conclusive but not sufficient for classification.
