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.
