Description of key information
In accordance with section 1 of REACH Annex XI, the hydrolysis study does not need to be conducted as Hydrocarbons, C14-20 Aliphatics (≤2%aromatics), are 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.
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.
The chemical constituents that comprise hydrocarbons, C14-20 Aliphatics (≤2% aromatics) consist entirely of carbon and hydrogen and do not contain hydrolysable groups. As such, they have a very low potential to hydrolyze. Therefore this degradative process will not contribute to their 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.
