Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

Trimethylolpropane was shown not to be readily biodegradable (Reference: Müller & Caspers, 1990), but fulfilled the criterion for inherent, ultimative biodegradability (70% degradability within 7 days) and was 100% inherently biodegradable after 28 days (Reference: Caspers & Müller, 1992).

The performance of a simulation test for ultimate degradation in surface water is scientifically not justified because the substance shows no hazard to humans or the environment and is inherently, ultimate biodegradable.

A sediment and a soil simulation test for biodegradation are not justified due to the low potential to adsorb to the sediment and to the soil and the resulting negligible exposure to sediment and soil.
