Description of key information
The ErC50/ ErC10 value based on growth rate was > 100 mg/L and EbC50 value based on yield was > 100 mg/L after 72 hours, respectively.
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 100 mg/L
- EC10 or NOEC for freshwater algae:
- 100 mg/L
Additional information
One study in freshwater algae is available for Ethyltriglycol methacrylate, which is considered reliable without restriction (Klimisch score 1; IBACON 2012 for Evonik).
In a 72 hour acute toxicity study (static dose-response test), the cultures of Pseudokirchneriella subcapitata strain no. 61.81 SAG were exposed to Ethyltriglycol methacrylate at nominal concentrations of 0, 6.25, 12.5, 25, 50, and 100 mg/L under static conditions in accordance with the guideline OECD 201. The ErC50 value based on growth rate was > 100 mg/L and
EbC50 value based on yield was > 100 mg/L after 72 hours, respectively.
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).
