Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

No studies investigating the adsorption/desorption behaviour of isopropyl isostearate (CAS No. 68171-33-5) are available. Using KOCWIN Program (v2.00), log Koc values of 5.88 and 5.05 were calculated, based on log Kow and on molecular connectivity index (MCI), respectively. The assessment is based on the MCI method, since the substance is outside the Kow range of the training set of the log Kow based method. Based on the calculated values, the substance has potential to adsorb.
