Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Aquatic PNEC values have to be treated with caution as they represent an unrealistic worst-case scenario. The effect values derived from the acute fish, Daphnia and algae toxicity tests are greater-than values, as no effects were observed at the highest concentrations tested. This should be considered for risk assessment purposes.

Conclusion on classification

Classification related key information

Biodegradation in water: screening tests: 113% (ThOD NH4) in 28 d (OECD 301F)

log Pow: -0.91 (OECD 104)

Acute toxicity:

to fish: LC50 (96 h) > 51 mg/L for Danio rerio (OECD 203)

to algae: ErC50 (72 h) > 51 mg/L for Pseudokirchneriella subcapitata (OECD 201)

to crustacea: EC50 (48 h) > 51 mg/L for Daphnia magna (OECD 202)

Chronic toxicity:

to fish: not available

to algae: NOErC (72 h) >= 51 mg/L for Pseudokirchneriella subcapitata (OECD 201)

to crustacea: not available

Classification justification according to CLP

Based on the data above, D-Glucopyranose, oligomeric, butyl glycoside 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 one trophic level - the lowest NOEC is >1 mg/L for algae. Therefore, D-Glucopyranose, oligomeric, butyl glycoside 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, oligomeric, butyl glycoside 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, oligomeric, butyl glycoside does not need to be classified and labelled as environmental hazard according to Directive 67/548/EEC.
