Description of key information
Additional information
Toxicity to terrestrial organisms is expected to be low.
One study investigating the long-term toxicity of D-Glucopyranose, oligomeric, butyl glycoside to soil macroorganisms is available (IBACON, 2012). In this key study with Eisenia fetida performed according to OECD 222 and GLP, no significant mortalities, body weight changes, behavioural abnormalities and feeding activity were observed in any of the treatments. Reproduction rates were significantly different compared to the control at the two lowest concentrations of 125 and 250 mg/kg soil, however this significance is not considered to be treatment-related as there was no dose relation and no statistically significant reduction of reproduction at the three higher concentrations of 200, 750 and 1000 mg/kg soil. As a conclusion, a NOEC of >= 1000 mg/kg dw soil is reported (i.e. the highest concentration tested).
Furthermore, there are reliable data for category member substances which are considered suitable for read-across based on a category approach. 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.
Two tests are available for the terrestrial compartment with the category member D-Glucopyranose, oligomeric, C10-16-alkyl glycosides. The tests were conducted with the annelid Eisenia sp. according to OECD guideline 207 and with plants according to OECD guideline 208 (Steber et al., 1995). No effects were observed up to 654 mg/kg in a short-term test with Eisenia sp. and in the tests with terrestrial plants as well. Since the category members are readily biodegradable, an indirect exposure via deposition of activated sludge to soil can be ruled out and persistency in soil is not expected. Because an indirect application to the soil compartment through sludge is unlikely, and no toxic effects were observed in soil macroorganisms and terrestrial plants in the highest concentration tested, no further testing is required.
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).
