Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The soil sorption coefficient Koc of diisopropylbenzene was calculated using EPIWIN v3.20, PCKOCWIN v1.66. The calculation yielded a value of 4036 (log Koc=3.606) indicating a strong sorption onto soil organic matter. The calculation of Koc based on molecular connectivity indexes yielded a value of 4000 and indicates that a strong sorption of diisopropylbenzene onto soil organic matter is to be expected. Based on the calculated Henry's Law constants (>1000 Pa x m³/mole), it is to be expected that m- and p-diisopropylbenzene are highly volatile from aqueous solution. According to the Mackay Level III calculation, the main target compartment of the distribution is air (ca. 99%) if the chemical is released into the air. If the chemical is released to the hydrosphere, the main target compartments are water (ca. 20 -23%) and sediment (ca. 75 -80%) and if the chemical is released to soil, the chemical remains predominantly in the soil compartment (ca. 98%).
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.
