Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 substances in the category are highly insoluble. For uptake by plants and microorganisms, the substance needs to go into solution (interstitial or pore water) before exposure can occur, therefore testing the substances in plants or microorganisms is considered irrelevant. This is not the case for uptake by earthworms and therefore a long-term toxicity study is proposed.
Based on results for biodegradation in water, it is proposed to run the tests on the members of the category with the longest chains:
acetalization product between glucose and C20/22(even numbered)-alcohol and acetalization product between glucose and C16/18(even numbered)-alcohol and to use these tests results for read across for the members of the category. This way, the possible toxicity on macroorganisms will be the worst case scenario for all members of the category including the substance Acetalization product between glucose and C12/18(even numbered)alcohol
According to a read-across strategy, taking into account the survival, growth and reproduction rates of the exposed adult test earthworms, the highest concentration of Acetalization product between glucose and C12/18(even numbered) alcohol without toxic effects on Eisenia fetida (NOEC) after the test period was determined to be at least 1000 mg/kg dry soil. NOEC reproduction on earthworms = 1000 mg/kg dw
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.
