Additional information

Aquatic toxicity potential of substance FAT 40066 was evaluated in studies conducted with fish, invertebrates, Lemna sp. and bacteria.


In a study conducted with Daphnia magna, the 48-h EC50 of FAT 40066 was determined to be >100.0 mg/l. In a study conducted with fish, the LC50 of FAT 40066 was determined to be 450 mg/L, while in studies with bacteria, the IC50 of the substance was determined to be >300 mg/L. Further, in a key study with Lemna, the EC50 for FAT 40066, was >100 mg/L. Hence, based on the above results, FAT 40066 can be considered as not toxic to the aquatic ecosystem.
