Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

2-EHA was negative in the bacterial Ames test with S. typhimurium strains TA 98, TA 100, TA 1535 and TA 1537 and E. coli WP2 uvr A (Jung et al., 1982; Zeiger et al., 1988; Warren et al., 1982), as well as in a HPRT locus assay with mammalian CHO cells (Schulz et al., 2007). In cultured human lymphocytes, 2-EHA induced a minimal increase in frequency of sister-chromatid exchanges (below 1.5 fold increase at concentrations of the test substance of 0.63 to 2.5 mM; Sipi et al., 1992), which is not considered significant.

In an in vivo micronucleus assay with mice, 2-EHA was administered by gavage up to the maximum tolerated oral dose of 1600 mg/kg/day. No bone marrow toxicity was observed, nor did the test substance induced any bone marrow micronuclei (Holstrom et al., 1994).


Short description of key information:
Overall, 2-EHA is considered not to be genotoxic.

Endpoint Conclusion: No adverse effect observed (negative)

Justification for classification or non-classification

Based on the available data, there is no concern for genotoxicity. Classification according to EU Directive 67/548/EEC and EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008 is therefore not warranted.
