Additional information

A reliable toxicity study (Best, 2014) with microorganisms is available for reaction mass of Amines, coco alkyl and ß-Alanine, N-(2-carboxyethyl)-, N-coco alkyl derivs. and ß-Alanine, N-coco alkyl derivs. and is included in this dossier.

The effect of the test item on the growth of Pseudomonas putida has been investigated over a 16-Hour period and gave an EL10 of 42 mg/L loading rate WAF and an EL50 of 130 mg/L loading rate WAF. The No Observed Effect Loading Rate (NOEL) after 16 hours exposure was 50 mg/L loading rate WAF.
