Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Genetic toxicity in vitro

Description of key information

2,2’-(C16-18 (evennumbered), alkyl imino) diethanol CAS No 1218787-30-4, has not been specifically tested but there is test data on 2,2’-(C16-18 (even numbered, C18 unsaturated) alkyl imino) diethanol CAS No 1218787-32-6 which was tested in the Ames bacterial reverse mutation assay.  There is also data which can be used for read across for another structurally related substance with a very similar carbon chain length distribution, 2,2'(Octadec-9-enylimino)bisethanol CAS No 25307-17-9 which was tested in two additional in-vitro genotoxicty studies to current protocol and carried out to GLP with well defined test substance.  Both these read across substances are more unsaturated and therefore more reactive than 2,2’-(C16-18 (evennumbered), alkyl imino) diethanol CAS No 1218787-30-4, so they are considered as a worst case for possible genetic toxicology.

Endpoint conclusion
Endpoint conclusion:
no adverse effect observed (negative)

Additional information

Additional information from genetic toxicity in vitro:

2,2’-(C16-18 (evennumbered), alkyl imino) diethanol CAS No 1218787-30-4, has not been specifically tested but there is test data on 2,2’-(C16-18 (even numbered, C18 unsaturated) alkyl imino) diethanol CAS No 1218787-32-6 which was tested in a bacterial reverse mutation assay (Ames) and was found not mutagenic with or without S9 mix. 2,2'(Octadec-9-enylimino)bisethanol CAS No 25307-17-9 a structurally similar substance was tested for mammalian cell gene mutation in the L5178Y TK +/- Mouse lymphoma assay and was not mutagenic. In addition it was tested in a Chromosomal aberration test in human lymphocytes in-vitro and was found to be not clastogenic. All tests were to current OECD/EU protocols carried out to GLP and with a clearly defined and described test substance. Based on this it can be concluded that 2,2’-(C16-18 (evennumbered), alkyl imino) diethanol CAS No 1218787-30-4, would not be expected to have any genotoxic hazard to human health.

Justification for classification or non-classification

2,2’-(C16-18 (evennumbered), alkyl imino) diethanol CAS No 1218787-30-4, has not been specifically tested but there is test data on two similar substances which are consistently negative and therefore it does not require classification as a mutagen according to the European Union CLP/GHS criteria.
