Description of key information
D-Glucopyranose, oligomeric, C10-16-alkyl polyglycosides (CAS: 110615-47-9) is considered to be harmful to aquatic algae under conditions tested.
Key value for chemical safety assessment
Additional information
The toxic effects of D-Glucopyranose, oligomeric, C10-16-alkyl polyglycosides (CAS: 110615-47-9) to marine and freshwater algae were evaluated. For the freshwater organisms the green algae Scenedesmus subspicatus was the most sensitive organism with an EC50 (72 h) of 12.5 mg a.i./L (Stelter, 1995). Another study exhibited an EC50 (72 h) for S. subspicatus of 19 mg a.i./L which is almost in the same range, and a related EC0 (72 h) of 2 mg/L for biomass (Rieche, 1994). The freshwater tests were performed according to Annex of 92/69/EWG and DIN 38412, part 9. For the marine algae (mainly Skeletonema costatum) the EC(L)50 (72 h) values ranged from 1.17 mg a.i./L – 9.85 mg a.i./L (Hudson, 2001 and 2003). Related NOEC (72 h) values of 1.8 mg a.i./L and 3.2 mg a.i./L were reported, respectively (Hudson, 2003). It should be considered that the lowest NOELR value of 0.5 mg a.i./L from the marine toxicity tests (Hudson, 2001) is based on nominal concentrations prepared by water accommodated fraction (WAF) without analytics, hence this value is not put forward for the assessment.
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.
