Additional information

According to the results of the present study, the test substance 2,3-Butandiol is not mutagenic in the Ames II Assay (Salmonella typhimurium reverse mutation assay) under the experimental conditions chosen.


Short description of key information:
The substance 2,3-Butandiol was tested for its mutagenic potential based on the ability to induce point mutations in selected loci of several strains of Salmonella typhimurium in a modified version of the traditional Ames test, the Ames II Assay (microtiter version).

Endpoint Conclusion: No adverse effect observed (negative)

Justification for classification or non-classification

No classification and labelling for genetic toxicity/mutagenic potential in bacteria is necessary according to Directive 67/548/EEC(DSD) or Regulation (EC) No 1272/2008 (GHS (EU-CLP)) criteria.
