Additional information
Conclusion on classification
Classification related key information
Biodegradation in water: screening tests: 82.25% (O2 consumption) in 28 d (OECD 301F)
log Pow: -1.3 (OECD 107)
Acute toxicity:
to fish: LC50 (96 h) = 101 mg a.i./L for Danio rerio (ISO 7346/1 -3; read-across)
to algae: ErC50 (72 h) > 150 mg/L for Pseudokirchneriella subcapitata (OECD 201)
to aquatic invertebrates: EC50 (48 h) > 100 mg/L for Daphnia magna (OECD 202)
Chronic toxicity:
to fish: NOEC (28 d) = 1.8 mg a.i./L for Brachydanio rerio (OECD 204; read-across)
to algae: NOErC (72 h) = 44.5 mg/L for Pseudokirchneriella subcapitata (OECD 201)
to aquatic invertebrates: NOEC (21 d) = 1.76 mg a.i./L for Daphnia magna (OECD 202 part II; read-across)
Classification justification according to CLP
Based on the data above, D-Glucopyranose, oligomeric, heptyl 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 three trophic levels - the lowest NOEC is >1 mg/L for Daphnia. Therefore, D-Glucopyranose, oligomeric, heptyl 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 (4thATP).
Classification justification according to DSD
Based on the data above, D-Glucopyranose, oligomeric, heptyl 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, heptyl glycoside does not need to be classified and labelled as environmental hazard according to Directive 67/548/EEC.
