Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

A carcinogenicity study may be required in accordance with REACH Regulation 1907/2006, Annex X, Section 8.9.1 of Column 1, Annex X. It is proposed to waive the need to conduct this study on the basis that available information indicate no concerns for carcinogenicity.

Justification for classification or non-classification

A carcinogenicity study may be required in accordance with REACH Regulation 1907/2006, Annex X, Section 8.9.1 of Column 1, Annex X. It is proposed to waive the need to conduct this study on the basis of:

1)    Negative findings in tests for gene mutation / mutagenicity.

2)    Molecular modelling studies performed by Kambia et al. (Kambia N, Renault N, Dilly S, Farce A, Dine T, Gressier B Luyckk M, Brunet C and Chavatte P. Molecular modelling of phthalates – PPARs interactions. Journal of Enzyme Inhibition and Medicinal Chemistry, 23(5): 611–616, 2008) indicate that TOTM, a structural analogue of the registered substance derived from a C8 -branched alcohol rather than a C8 -linear alcohol, is not able to fit into PPARα and PPARγ binding sites due to its larger size relative to the corresponding phthalate ester, implying that any predicted activity may not actually be able to occur.

 

With these considerations it is concluded that there is sufficient evidence to justify the non-classification of the registered substance for carcinogenicity.
