Additional information
Two key studies are available investigating the short-term toxicity of D-Glucopyranose, oligomeric, C10-16-alkyl glycosides, carboxymethyl ethers, sodium salts (CAS 383178-66-3) to aquatic invertebrates.
One study investigated the short-term toxicity to freshwater invertebrates according to OECD guideline 203 and GLP using Daphnia magna as test organism (Noack 2007). Test concentrations between 50 and 800 mg/L were tested under static conditions. No mortality was observed in the control and the 50 and 100 mg/L treatments. All test organisms died in the 400 and 800 mg/L treatments during an exposure time of 48 h. The 48h-EC50 value was determined to be 172 mg/L based on the nominal test concentration.
The second study investigated the short-term toxicity to marine invertebrates according to ISO guideline 14669 and GLP using Acartia tonsa as test organism. The static study tested concentrations between 0.96 and 30.5 mg a.i/L. No mortality was observed in the control and the 0.96 and and 3 mg a.i./L treatment. All test organisms died in the 9.6 and 30.5 mg a.i./L treatments during an exposure time of 48 h. Thus, the 48h-EC50 value was determined to be 6.83 mg a.i./L based on the nominal test concentration.
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.
