Description of key information

Tests with fish, Daphnia and green algae have been conducted with TGIC showing moderate to low toxicity in the short-term assay. 
Long-term tests with these ortganisms are expected to show similar toxicity with the NOEC 2-4 times lower than in the short-term assay. However, as all three organisms showed LC50 or EC50 in the same range, it is to be expected that tests with other aquatic organisms will be in the same range.
In addition, TGIC is rapidly hydrolized in water to form 1,3,5-tris(hydroxypropyl)-1,3,5-triazine-2,4,6-(1H, 3H, 5H)-trion, an alcohol of rather low toxicity as can be expected from other alcohols (phloroglucinol, CAS no. 108-73-6).

Additional information

Based on the low toxicity in fish , Daphnia and algae in fresh-water, and the similarity of the toxicity endpoints, it is expected that tests with other aquatic organisms will lead to the same range of toxicity.

TGIC is rapidly hydrolized in water, and thus aquatic organisms are mainly exposed to the degradation product, 1,3,5-tris(hydroxypropyl)-1,3,5-triazine-2,4,6-(1H, 3H, 5H)-trione. This degradation product is expected to be of low toxicity as it represents an alcohol, and alcohols are generally of low toxicity. Therefore, no other water-borne organisms have been tested.
