Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Adsorption / desorption
The adsorption coefficient (Koc) of the test material was determined using the HPLC screening method in accordance with OECD Guideline 121 (Garcia-Sanchez, 2011). The column temperature of the HPLC system was 40 °C. The reference Koc-values in the OECD guideline presumably refer to 25 °C. Even though the column temperature was 40 °C, this temperature has no influence on the result of the determination. Therefore the Koc -value of the test item determined within this study also refers to 25 °C. As result a logKoc greater than 5 is reported, the extrapolated value is 6.4 (corresponding to a Koc value of 2,511,886).
Furthermore, the soil adsorption potential for bis(2,6-diisopropylphenyl)carbodiimide was predicted by the computer program KOCWIN v2.01 (EPIWIN software) by US-EPA. A Koc value of 17,320,000 L/kg was estimated by the Salbjic molecular connectivity (MCI) method, which is taken more seriously into account, due to the fact that it includes improved correction factors. The traditional method gives a value of 36,960,000 L/kg.
Henry´s Law constant
This information is not mandatory for a registration under REACH Regulation (EC) 1907/2006 in a tonnage band of 100 - 1000 tons/year. However, the HLC is important to derivate the PNECs for the ecotoxicology chapter. It can be predicted with the help of HENRYWIN v3.20 (EPIWIN software) by US-EPA (Chemservice S.A., 2011). A constant of 2.93 E+001 Pa*m³/mol was predicted at 25 °C for the substance bis-(2,6-diisopropylphenyl)carbodiimide.
Distribution modelling and other distribution data
According to REACH Regulation 1907/2006 this information is not mandatory for a registration of a chemical at a tonnage band of 100 - 1000 tons/year.
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.
