Description of key information
There is a high probability that the product is not acutely harmful to aquatic algae.
Key value for chemical safety assessment
Additional information
The toxicity of the test item to aquatic algae was assessed in a GLP study according to OECD guideline 201. The study was conducted as limit test with a nominal concentration of 100 mg/L as saturated solution. Due to the very low water solubility of < 10 µg/L an analytical concentration control analysis could not be performed. The test item had no inhibitory effects on the growth rate of Pseudokirchneriella subcapitata. The ErC50 was determined to be > 100 mg/L nominal loading rate (saturated solution).
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).
