Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Adsorption / desorption:

Experimental and Predicted data of adsorption endpoint for the target chemical Octyl acetate (Cas no. 112-14-1) and its read across chemical were reviewed to summarize as follows:  


From predicted model EPI suite 2016 indicate that the soil adsorption coefficient (Koc) value of chemical Octyl acetate is estimated to be 204.5 L/kg (log KOC = 2.310) by means of MCI method at 25 deg.C, indicating that it is has a Moderate sorption to soil and sediment and therefore have slow migration potential to groundwater. 


Whereas from chemspider predicted database the soil adsorption coefficient i.e Koc value of test substance Octyl acetate was estimated to be 2921.84 L/Kg i.e Log Koc= 3.465 at pH 5.5 and 7.4. This Koc value indicates that the substance Octyl acetate has a Moderate sorption to soil and sediment and therefore have slow migration potential to groundwater.   


From HSDB database; 2016 the read across chemical Cyclohexyl acetate (Cas no. 622-45-7) indicate the adsorption coefficient (Koc) of substance Cyclohexyl acetate was found to be 650 using an estimated log Kow of 2.64 and a regression-derived equation.This Koc value suggests that cyclohexyl acetate is expected to have low mobility in soil.

Thus based on the above all studies it is concluded that the test substance Octyl acetate (Cas no. 112-14-1) has low mobility in soil/sediment.
