- Conclusions:
- After 72 hours, the Test Item showed a EC50 between 102,00 mg/l and 327,70 mg/l. The Test Item is therefore considered practically not toxic.
- Executive summary:
A sample of ALKANOLAMINE FATTY ESTER COMPOUNDS was in this study assessed for toxicity properties by exposing the substance to the marine algae Skeletonema costatum. After 72 hours, the Test Item showed a EC50 between 102,00 mg/l and 327,70 mg/l. The Test Item is therefore considered practically not toxic.
