Endpoint summary
Administrative data
Key value for chemical safety assessment
Genetic toxicity in vitro
Description of key information
In a reliable and GLP guideline study, the substance showed no evidence of mutagenicity in a bacterial reverse mutation (Ames) assay in Salmonella typhimurium strains TA98, TA100, TA1535 and TA1537 and Escherichia coli strain WP2uvra, with or without metabolic activation. An older study using bacterial strains TA98, TA100, TA1535 and TA1537 and 87% pure 2-(2-(2-butoxyethoxy)ethoxy)ethanol similarly did not cause an increase in mutations when tested at up to 5mg/plate with and without S9 metabolic activation using both a standard plate incorporation and pre-incubation methods of application.
In a guideline and GLP in vitro chromosome abberation study using human blood lymphocytes, 2 -(2 -(2-butoxyethoxy)ethoxy)ethanol did not induce chromosomal aberrations in human lymphocytes with our without metabolic activation.
In a guideline and GLP HPRT mammalian cell gene mutation assay using Chinese Hamster lung fibroblasts, the substance 2 -(2 -(2 -butoxyethoxy)ethoxy)ethanol was unable to induce gene mutations and therefore considered negative in the assay.
Endpoint conclusion
- Endpoint conclusion:
- no adverse effect observed (negative)
Genetic toxicity in vivo
Endpoint conclusion
- Endpoint conclusion:
- no adverse effect observed (negative)
Additional information
Justification for classification or non-classification
From the available data, there is no indication of the substance having genotoxic or mutagenic properties, therefore classification is not warranted.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
