Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

TGIC is inherently biodegradable in municipal sewage sludge which has not been adapted.
The highest degradation rate was 48% , the lowest 0% with several values in between.
Much of the variability of the results was dependent on the solubility in the incubation solution, as increasing the total salt concentration is reducing the solubility of TGIC.

Key value for chemical safety assessment

Biodegradation in water:
inherently biodegradable, not fulfilling specific criteria

Additional information

TGIC is inherently biodegradable in municipal sewage sludge, although the results on one test with GLP showed less than 1% degradation. However, in two tests with different end points (Zahn-Wellens test [302 B] and a Ready Biodegradability test [301 B] showed up to 44 and 48% degradation at the lower concentration tested. In addition, TGIC is hydrolized in water with a half life of 160 hours.

Biodegradation is hampered by the solubility in buffered salt solutions as required for the test.

However, under certain conditions degradation was as high as 48% as measured by CO2 generation in standard biodegradation tests.
