Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Alchisor CAL 145 comprises alkenes C13-14 hydroformylation products with read-across from the chemically-similar Alchisor CAL 123 as defined in the `Read-Across Justification Document'. Where environmental fate data exist for Alchisor CAL 123, these are representative of the Alchisor CAL 145 substance.
In accordance with Annex VIII Column 2 of Regulation (EC) No 1907/2006 REACH concerning the Registration, Evaluation, Authorisation and Restriction of Chemicals, the adsorption/desorption screening test (required in Section 9.3.1) does not need to be conducted as the substance and its relevant degradation products decompose rapidly.
Despite not being a mandatory information requirement Alchisor CAL 123 was assessed for its absorption/desorption potential by determining the Log Koc. In a reliable (Klimisch 1; Klimisch 2 when used for read-across) GLP compliant study conducted according to OECD Guideline 121 (Estimation of the Adsorption Coefficient (Koc) on Soil and on Sewage Sludge using High Performance Liquid Chromatography (HPLC)) the extrapolated Log Koc of Behenyl Bottoms was found to be> 6.91.
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.
