Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The ready biodegradability of MGK 264 was assessed in the CO2 Evolution test.
Mean cumulative CO2 production by mixtures containing MGK 264 was negligible and had achieved, at most, 3% of the theoretical value (TCO2,110.1 mg CO2) by the end of the test on Day 29.
Substances are considered to be readily biodegradable in this test if CO2 production is equal to or greater than 60% of the theoretical value within 10 days of the level achieving 10%. MGK 264 cannot, therefore, be considered to be readily biodegradable.
In both the aerobic and anaerobic soil metabolism studies mass balance was maintained. Degradates were observed to increase in the soil extracts of both the aerobic and anaerobic studies and the aqueous phase of the anaerobic study. Volatile degradates increased throughout the duration of both studies. The half-life determinations were calculated using first-order kinetics.
In the aerobic study half-lives for the 14C hexyl-and norbornene-MGK 264 was 294 days (r = 0.9607) and 388 days (r = 0.9556), respectively. The average half-life for both the labels is 341 days.
In the anaerobic study the half-life for the 14C-hexyl-MGK 264 was 174 days (r = 0.9423). The half-life for the 14C-norbornene-MGK 264 was 365 days (r = 0.8247). The average half-life for both the labels is 270 days.
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.
