Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Stability:
The registered substance 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 8.1 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.
Biodegradation:
The registered substance is expected to be readily biodegradable (83% in 28 days) based on aerobic biodegradation studies using standard OECD test guidelines; and also exhibits a high extent of biodegradability in soil (99%). Therefore, biotic degradation will significantly contribute to the loss of this substance from the environment.
Bioaccumulation:
Experimental data for the registered substance suggests that the substance has a very low potential to bioaccumulate with a mean lipid-normalized steady-state BCF of 21 L/kg, and a lipid-corrected dietary BMF value <= 0.016 (growth corrected whole body half life < 0.55 days).
Transport and distribution:
Soil adsorption of the registered substance is expected to occur to a moderate degree (log Koc = 2.62). This estimated log Koc value aligns well with measured test log Koc data ranging from 2.59 to 2.75 for similar substances.
Henry’s Law constant (7.71 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 the registered substance will partition largely to the soil compartment, followed by the water, then air, and minimally to the sediment compartment.
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.
