Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

Studies with organisms from the aquatic and terrestrial compartment are available and thus, the PNECs are based on the test results and assessment factors recommended in the Technical Guidance Document (ECHA, 2008) have been applied. For the freshwater sediment, no studies have been conducted and the PNECs have been calculated using the Equilibrium Partitioning Method (EPM) as screening values. The EPM was used for the the calculation of the PNEC sediment (marine water) as well because only short-term studies are available.

The PNEC oral is derived from a toxicological endpoint as the toxicity towards birds has not been tested.

Conclusion on classification

Classification related key information

Biodegradation in water: screening tests: 100% (DOC removal) in 28 d (OECD 301E)

log Kow: <1.77 (deduced from similar substances)

Acute toxicity:

to fish: LC50 (96 h) = 100.81 mg/L for Brachydanio rerio (ISO 7346/1 -3)

to algae: ErC50 (72 h) = 27.22 mg/L for Scenedesmus subspicatus (DIN 38412, part 9)

to crustacea: EC50 (48 h) > 100 mg/L for Daphnia magna (OECD 202)

Chronic toxicity:

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

to algae: NOErC (72 h) = 6 mg/L for Skeletonema costatum (ISO 10253)

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

Classification justification according to CLP

Based on the data above, D-Glucopyranose, oligomers, decyl octyl 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 Daphnia. Valid chronic toxicity data are available for three trophic levels - the lowest EC10 is 1.76 mg/L for Daphnia. Therefore, D-Glucopyranose, oligomers, decyl octyl 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, decyl octyl 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, Daphnia and algae. D-Glucopyranose, oligomers, decyl octyl glycosides does not need to be classified and labelled as environmental hazard according to Directive 67/548/EEC.
