Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Administrative data

Key value for chemical safety assessment

Additional information

In all in-vitro genetic toxicity assays (Ames test, MNT, V79/HGPRT test), 3,9-Di-3-cyclohexen-1-yl-2,4,8,10-tetraspiro[5.5]undecane

was negative.

Justification for selection of genetic toxicity endpoint
The results of the Ames tests, the in-vitro MNT test and the HPRT test were considered

Short description of key information:
3,9 -Di-3 -cyclohexen-1 -yl-2,4,8,10 -tetraspiro[5.5]undecane, CAS 6600-31-3 was investigated in 2 Salmonella/microsome tests (Ames tests). Result: negative, no evidence of mutagenic activity was seen (with and without mutagenic activation). Additional, 3,9 -Di-3 -cyclohexen-1 -yl-2,4,8,10 -tetraspiro[5.5]undecane was evaluated as negative in an in-vitro MNT and also in a V79/HGPRT test.

Endpoint Conclusion: No adverse effect observed (negative)

Justification for classification or non-classification

Due to the negative reaults in all available in-vitro genetic toxicity tests a classification is not justified.
