Description of key information
Additional information
Hydrolysis rate constants cannot be estimated for isononanol with EPI Win. This is because the hydrolysis of an alcohol, i.e. the reaction with water at the C atom bearing the OH-group, would result in the very same alcohol. Therefore, isononanol is stable in water (GUBDH, 2008)
3,5,5 -trimethylhexan-1-ol was not readily biodegradable in the MITI-I test (i.e. OECD 301C) (CERI 2007; NITE; 2002).
The bioconcentration was low in the carp. The values ranged between 4 and 6.3 at test material concentration of 10 µg/L and 3.9 to 8.1 µg/L at 100 µg/L (NITE; 2002).
Model calculations using Mackay Level III fugacity model indicates that the chemical has a strong tendency to absorb to soil following release into soil, air, or water (N.N. 2002).
Note: a full OECD SIDS documentation is available for this chemical which passed the OECD-ICCA/HPV program without further testing, with reference to exposure limitations as it was regarded to be an intermediate; cf. chapter 13 for further details.
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.
