Key value for chemical safety assessment

Additional information

No study is available in which the toxicity of D-Glucopyranose, oligomeric, undecyl glycoside (CAS 98283-67-1) to terrestrial plants was tested. In accordance to the Regulation (EC) No 1907/2006 Annex XI, 1.5 a read across was conducted to a study with the structurally related category member substance D-Glucopyranose, oligomeric, C10-16-alkyl glycosides (CAS 110615-47-9). The read across approach is justified in the overall summary of IUCLID Chapter 6.1 and in detail within the category justification attached in IUCLID Section 13.

The effects of D-Glucopyranose, oligomeric, C10-16-alkyl glycosides (CAS 110615-47-9) to terrestrial plants were evaluated in a laboratory test according to the OECD guideline 208. Seeds from oat (Avena sativa), turnip (Brassica rapa) and tomato (Lycopersicon esculentum) were used for the test (Steber et al., 1995). After the test duration of 14 d no adverse effects on the germination of the seeds were observed in the highest test concentration of 654 mg/kg.
