Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Conclusion on classification

Classification related key information

Biodegradation in water: screening tests: 66.9% (CO2 evolution) in 28 d (Modified OECD Screening test conditions)

log Pow: <=2.41 (worst-case QSAR, KOWWIN)

Acute toxicity:

to fish: LC50 (96 h) = 2.95 mg/L for Brachydanio rerio (EU C.1)

to algae: ErL50 (72 h) = 9.05 mg/L for Skeletonema costatum (ISO 10253)

to crustacea: EL50 (48 h) = 26.2 mg/L for Acartia tonsa (ISO 14669)

Chronic toxicity:

to fish: NOEC (28 d) = 1.8 mg/L for Brachydanio rerio (OECD 204)

to algae: NOELR (72 h) = 5 mg/L for Skeletonema costatum (ISO 10253)

to crustacea: EC10 (21 d) = 1.76 mg/L for Daphnia magna (OECD 202 part II)

Classification justification according to CLP

Based on the data above, D-Glucopyranose, oligomers, branched and linear C9 -11 -alkyl glycosides is considered to be rapidly degradable and have low potential for bioaccumulation. The acute aquatic toxicity L(E)C50 values are > 1 mg/L for fish, algae and aquatic invertebrates. Valid chronic toxicity data are available - the lowest EC10 value is 1.76 mg/L for Daphnia. Therefore, D-Glucopyranose, oligomers, branched and linear C9 -11 -alkyl glycosides does not need to be classified and labelled as environmental hazard according to the Regulation (EC) No.1272/2008 (CLP) and the Regulation (EU) No. 286/2011 (2ndATP).

Classification justification according to DSD

Based on the data above, D-Glucopyranose, oligomers, branched and linear C9 -11 -alkyl glycosides is considered to be rapidly degradable and have low potential for bioaccumulation. The acute aquatic toxicity L(E)C50 values are > 1 mg/L for fish, aquatic invertebrates and algae. D-Glucopyranose, oligomers, branched and linear C9 -11 -alkyl glycosides does not need to be classified and labelled as environmental hazard according to Directive 67/548/EEC.
