Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

The toxicity (LC50 and chronic toxicity value) is estimated by using ECOSAR v1.00. Two models are available, the estimation form the Class (aliphatic amines) and the Baseline Toxicity (neutral organic structure analysis relationship). In general, the values for toxicity estimated by neutral structure SAR are higher and therefore the estimated toxicity lower compared to the estimation based on the class (aliphatic amines). Lowest EC50, were observed for green algae, at 500.805 mg/L and lowest chronic toxicity value for daphnia and mysid (saltwater) at 0.093 mg/L. However, the estimation by calculation only provides an approximation and can not replace empirical studies. The experimental study aquatic short-term toxicity on fish shows, that the LC50 is > 5000 mg/L.

Conclusion on classification

The predicted aquatic toxicity from experimental results shows, that the acute toxicity for sodium N-methyltaurinate is > 5000 mg/L in addition the LC50 and EC50 values estimated by calculation for fish, aquatic invertebrates and algae are > 100 mg/L, confirm, that sodium N-methyltaurinate does not have to be classified.
