Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The adsorption coefficient for MTCP Crude is estimated to be log Koc = 3.2 (Koc = 1585) on the basis of read-across from a suitable structural analogue.
Key value for chemical safety assessment
- Koc at 20 °C:
- 1 585
Additional information
An appropriate structural analogue (3-methyl-5-(2,2,3-trimethylcyclopent-3-en-1-yl)pent-4-en-2-ol), tradename Ebanol, has been tested for adsorption / desorption.
The chromatograms of Ebanol show one peak at an average retention time of 7.25 minutes, corresponding to an adsorption coefficient (log value) of 3.2.
On the basis that the test material (Ebanol) is being used to support MTCP Crude on the basis of read-across, the adsorption-coefficient (log value) of MTCP Crude is considered to also be 3.2.
[LogKoc: 3.2]
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
