Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Hydrolysis:
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.
Alkanes, C16 -47, branched and linear 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.
Biodegradation:
The results from the ready biodegradability studies for GTL Base Oil Distillates ranged from 11-67% after 28 days. The main factors influencing the results include the guideline/method followed, the dosing method and the viscosity/composition of the test substance. In general, the biodegradability of the subtances decrease as the viscosity (and hence carbon chain length/degree of branching) increases. In fact, the lowest viscosity substances almost meet the criteria for ready biodegradability. Overall GTL Base Oil Distillates is not considered to be readily biodegradable but is expected to be inherently biodegradable.
This data is used for read across to Alkanes, C16 -47, branched and linear.
Adsorption / desorption:
The adsorption coefficient (Koc) of the test material (C18-C50 branched, cyclic and linear hydrocarbons – Distillates (CAS# 848301-69-9) was determined to be >4.27 x 10E5, log10 Koc >5.63.
This data is used for read across to Alkanes, C16 -47, branched and linear.
Additional information
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.
