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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key value for chemical safety assessment
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) using 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 (C12-18, 1-2.5 EO) Na (CAS 68081-91-4) can be considered as non-genotoxic.

Justification for selection of genetic toxicity endpoint
No study selected as all three studies were negative.
Short description of key information:
In vitro gene mutation:
Bacterial reverse mutation assay (Ames test / OECD guideline 471): negative
In vitro mammalian cell gene mutation assay (MLA / OECD guideline 476): negative
In vivo:
Mammalian Bone Marrow Chromosome Aberration Test (OECD 475): negative
Endpoint Conclusion: No adverse effect observed (negative)
Justification for classification or non-classification
Classification criteria according to 67/548/EEC and (EC) 1272/2008 are not fulfilled.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
