Additional information

Conclusion on classification

Biodegradation:

·        Biodegradation in water: 85% (based on ThOD(NH4)) in 28 d; 10-day window passed (OECD 301 F)

 

Bioaccumulation:

·        log Kow: – 2.58 - 2.41 (EPI Suite v3.20, KOWWIN v1.67)

 

Acute toxicity:

·        to fish: LL50 (96 h) > 37.6 mg/L (nominal, WAF), OECD 203 as adapted by OSPAR commission (ref number 2005-11)

·        to aquatic invertebrates: LL50 (48 h, Acartia tonsa) = 60.19 mg/L (nominal, WAF), ISO 14669 (1999)

·        to algae: ErL50 (72 h, Skeletonema costatum) = 37.5 mg/L (nominal, WAF), ISO 10253, ISO 5667-16 and EPA/600/4-85/013

 

Chronic toxicity:

·        to fish:NOEC (28 d, Danio rerio) = 1.8 mg a.i./L,OECD 204; read across(CAS 110615-47-9)

·        to aquatic invertebrates: EC10 (21 d, Daphnia magna) = 1.76 mg a.i./L (nominal) based on mortality, OECD 202; read across (CAS 110615-47-9)

·        to algae: NOELrR (72 h, Skeletonema costatum) = 10 mg/L (nominal, WAF), ISO 10253, ISO 5667-16 and EPA/600/4-85/013

 

Classification justification according to CLP

Based on the data above, D-Glucopyranose, oligomeric, undecyl glycoside (CAS 98283-67-1) is considered to be rapidly degradable and to have a low potential for bioaccumulation. The acute aquatic toxicity L(E)L50 values are > 1 mg/L for fish, algae and Daphnia. Valid chronic toxicity data are available for three trophic levels - the lowest NOEC is >1 mg/L. Therefore, D-Glucopyranose, oligomeric, undecyl glycoside does not need to be classified and labelled as hazardous to the environment according to the Regulation (EC) No.1272/2008 (CLP) and the Regulation (EU) No. 286/2011 (6th ATP).
