Additional information
One study investigating the short-term toxicity of D-Glucopyranose, oligomers, branched and linear C9-11-alkyl glycosides (CAS 157707 -87 -4) to marine fish is available. In this key study performed according to an OSPARCOM guideline (1995 -7, modified OECD 203) and GLP, the marine fish Scophthalmus maximus was exposed to one nominal concentration of 1 mg/L of a 48 -52% solution in a semi-static test design. No effects were observed. As a result, an LL50 (96 h) of >= 0.5 mg a.i./L was reported (Opus Plus Ltd., 2006).
Another key study is available for the category member D-Glucopyranose, oligomeric, C10-16-alkyl polyglycosides, performed according to EU method C.1 and GLP (Henkel, 1995), which is considered suitable for read-across based on a category approach. In this study, Brachydanio rerio was tested at nominal concentrations of 2, 4, 8 and 16 mg/L and exhibited an LC50 (96 h) of 2.95 mg a.i./L (Henkel, 1995).
This read-across is in accordance with Regulation (EC) No. 1907/2006 Annex XI, 1.5 and justified in detail in the overall summary (IUCLID Chapter 6.1) and within the category justification attached in IUCLID Section 13. In this case of read-across, the best suited (highest degree of structural similarity, nearest physico-chemical properties) read-across substance was used for the assessment. Nevertheless, as it can be seen in the data matrix of the category justification in IUCLID Section 13 and the overall summary (IUCLID Chapter 6.1), all reliable data in the category support the hazard assessment of each category member by showing a consistent pattern of results.
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).
