Description of key information

Additional information

There are no data available on terrestrial endpoints of Reaction products of D-Glucose, n-Butanol and C10-12 (even numbered) alcohols. However, 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.

Toxicity to terrestrial organisms is expected to be low. Two tests are available for the terrestrial compartment with the category member and component of the substance 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.
