Additional information
One algae study for Betaines, C12-14 (even numbered)-alkyldimethyl, EC No. 931-700-2 is available. The study is conducted according to OECD 201 and revealed an EC50 of 1.7 mg/L (measured concentration of active ingredient)
for the tested substance and a NOEC of 0.38 mg/L (Hutchinson, 2010).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.
