Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Alchisor CAL 111 is thetrade name for decene, hydroformylation products, high boiling. As defined in the ‘Read-Across Justification Document’, data provided for the analogue substance Alchisor CAL 123 is representative of Alchisor CAL 111 and suitable for assessment purpose.
Study data for Alchisor CAL 123, where available, have been evaluated and considered for assessment. No environmental fate data are available for Alchisor CAL 111.
Alchisor CAL 123 comprises alkenes C11-12, hydroformylation products, distillation residues. A reliable study (Klimisch score 1),GLP compliant OECD Guideline 301B (Ready Biodegradability: CO2 Evolution Test) showed that the test substance biodegraded to an extent of 87.7% after 28 days with an unacclimated sewage sludge inoculum. The test substance did not achieve 60% degradation with a 10-day window for ready biodegradability. As Alchisor CAL 123 is a mixture, the 10-day window test is not applicable as the only determination of ready biodegradability since different components of the mixture can degrade preferentially (OECD TG 103C). Therefore, Alchisor CAL 123 is considered“readily biodegradable” in water.
In Annex IX column 2 of the REACH Regulation, it says that a study on the "Biodegradation in Water and Sediment” and a study on “Biodegradation in soil” does not need to be conducted if the substance is “readily biodegradable". Therefore, a study on the "Biodegradation in Water and Sediment” and a study on “Biodegradation in soil” " does not have to be conducted for Alchisor CAL111.
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.
