Description of key information
The 48h-EC50 for Daphnia magna exposed to Methanaminium N,N,N-trimethyl-, salt with 2,2-dimethylpropanoic acid was experimentally determined to be 11 mg/l.
The effect of Methanaminium N,N,N-trimethyl-, salt with 2,2-dimethylpropanoic acid on the growth of Pseudokirchneriella subcapitata has been investigated and results in EC50 values > 100 mg/l and a No Observed Effect Concentration (NOEC) of 100 mg/l.
Fish Acute Toxicity of Methanaminium, N,N,N-trimethyl-, salt with 2,2-dimethylpropanoic acid (1:1) was determined using Fish Acute Toxicity Test (OECD 203) with Pimephales promelas. The probit method resulted in an LC50 of 581.4 mg/L with 95% confidence intervals of 473.2 and 709.1.
Testing the acute toxicity of the test substance of Methanaminium N,N,N-trimethyl-, salt with 2,2-dimethylpropanoic acid (1 :1) to Rare minnow (Gobiocypris rarus) resulted in a 96 h-LCso > 100 mg/L (mean measured concentration 86 .7 mg/L);
The long-term toxicity test to Daphnia magna with the the test substance of Methanaminium N,N,N-trimethyl-, salt with 2,2-dimethylpropanoic acid (1 :1) under valid semi-static test conditions (72h-renewal) resulted in the lowest observed effect concentration (LOEC) was 0.091 mg/L(the average measured concentration 0.080 mg/L) and the no observed effect concentration (NOEC) was 0.061 mg/L (the average measured concentration 0.050 mg/L). For survival of adults the LOEC was 0.091 mg/L (the average measured concentration 0.080 mg/L), the NOEC was 0.061 mg/L (the average measured concentration 0.050 mg/L).
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
