Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Alcohols, C8-10-iso, C9-rich has the potential to degrade in the atmosphere from hydroxyl radical attack and photodegradation can be a predominant daylight atmospheric degradation process for this substance (half-life 8.8 hours).

Aliphatic alcohols are resistant to hydrolysis, and will not undergo direct photolysis in water and soil. As such, these fate processes will not contribute to a measurable loss of this substance from the environment.


Alcohols, C8-10-iso, C9-rich, is expected to be readily biodegradable (98% in 28 days) based on aerobic biodegradation studies using standard OECD test guidelines.  Therefore, biotic degradation will significantly contribute to the loss of this substance from the environment.



Experimental data for an analogue substance along with the biochemical evidence suggest that this substance has a very low potential for bioconcentration in aquatic species and is not expected to bioaccumulate.


Transport and distribution:

Soil adsorption of Alcohols, C8-10-iso, C9-rich is expected to occur to a moderate degree (log Koc = 2.45).

Henry's Law constant (6.54 Pa.m3/mole) indicates that volatilization from water is not expected to occur at a rapid rate, but may occur at a significant rate.

Distribution modeling estimates that Alcohols, C8 -10 -iso, C9 -rich will partition largely to the soil compartment (ca. 68%), followed by the water (ca. 30%), and minimally to air (ca. 2.1%), and sediment (0.1%) compartments.
