Description of key information

Not anticipated to be carcinogenic.

Key value for chemical safety assessment

Justification for classification or non-classification

No classification for carcinogenicity is indicated according to the general classification and labeling requirements for dangerous substances and preparations (Directive 67-548-EEC) or the classification, labeling and packaging (CLP) regulation (EC) No 1272/2008.

Additional information

Studies have not been performed to test the carcinogenic potential of isononanol.  However, based on other endpoints, it is not expected to present a carcinogenic hazard.  As described in section 7.1 - Toxicokinetic studies for Alcohols, C7 -9 -iso, C8 -rich (Isooctanol; Exxal 8) CAS number 68526 -83 -0 and Alcohols, C11 -C14 iso, C13 -rich (Isotridecanol: Exxal 13) CAS number 68526 -86 -3 will be conducted in 2017 and finalized in 2017 -2018. This information will be used to determine if these alcohols are efficiently metabolized as expected based on data from linear and branched chain alcohols. Furthermore, there are no structural alerts to suggest these compounds are inherently carcinogenic. Finally, in multiple in vitro genetic toxicity studies show no evidence of mutagenic potential has been identified.
