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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
In accordance with section 1 of REACH Annex XI, the hydrolysis study does not need to be conducted as Docosane is not expected to undergo hydrolysis in the environment due to a lack of hydrolyzable functional groups and therefore not conducting the test is scientifically justifiable. Furthermore, the substance is poorly soluble in water. Therefore, in accordance with Column 2 of REACH Annex VIII, the hydrolysis study (section 9.2.2.1) does not need to be conducted.
Key value for chemical safety assessment
Additional information
Hydrolysis is a reaction in which a water molecule of hydroxide ion substitutes for another atom of group of atoms present in a chemical resulting in a structural change of that chemical. Potentially hydrolysable groups include alkyl halides, amides, carbamates, carboxylic acid esters and lactone epoxides, phosphate esters, and sulfonic acid esters. The lack of a suitable leaving group renders compounds resistant to hydrolysis.
Docosane does not contain hydrolysable groups and has a very low potential to hydrolyze. Therefore this degradative process will not contribute to its removal from the environment.
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.
