Additional information

In some cases the CAS and chemical identity stated refer to SDA nomenclature for this substance. In REACH substance identification it is necessary to be more specific as to the chain lengths present. Full details may be found in the CSR.

Conclusion on classification

Nonanol, branched and linear is readily biodegradable and long-term QSAR estimate aquatic invertebrate NOECs between 0.01 and 1 mg/l (21 d NOEC 0.04 -0.17 mg/l).

Therefore, the substanceis classified as Chronic Category 3 for the environment in the EU according to Regulation (EC) No. 1272/2008.
