Additional information
The following experimental ecotoxicological results are available:
LC50 (96h) > 1000 mg/L, LC0 (96h) ≥ 1000 mg/L, NOEC (96h) ≥ 1000 mg/L for rainbow trout (Oncorhynchus mykiss) (OECD 203, static)
NOEC (24h & 48h) ≥ 100 mg/L, EC50( 24h & 48h) > 100 mg/L for Daphnia magna (OECD 202, static)
NOEC (72h, growth rate & yield) ≥ 100 mg/L, LOEC, EC10, EC50 (72h, growth rate & yield) > 100 mg/L for Desmodesmus subspicatus (OECD 201, EU method C.3, static)
EC0 ≥ 10000 mg/L, EC10 > 10000 mg/L, EC50 > 10000 mg/L over 16h for Pseudomonas putida [Safepharm Laboratories Standard Test Method 932.03 following the recommendations of the German Water Hazard Classification Scheme (Bewertung Wassergefährdender Stoffe LTWS - Nr 10) / ISO 10712)]
The substance arises no toxicity concern for the environmental compartment.
Conclusion on classification
Considering all available data of the acute toxicity tests on aquatic organisms, environmental fate issues and taking into account the provisions laid down in Council Directive 67/548/EEC and Regulation (EC) No. 1272 /2008, the substance does not need to be classified with respect to acute and long-term toxicity towards environmental organisms.
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.
