Additional information

Conclusion on classification

Classification related key information

 

Biodegradation in water: Readily biodegradable

Bioaccumulation in organisms is negligible, due to biotransformation and excretion of alcohol ethoxylates.

 

Acute toxicity:

Fish: LC50 (96h) = 1.2 mg/L

Crustacea: EC50 (48h) = 0.39 mg/L

Algae: ErC50 (72h) = 0.43 mg/L

Chronic toxicity:

The risk assessment is based on alcohol ethoxylate specific QSARs

Fish: EC20 (30d) >= 2.92 - <= 5.14 mg/L

Crustacea: EC20 (21d) >= 3.72 - <= 6.55 mg/L

Algae: ErC20 (72h) >=3.23 - <= 5.67 mg/L

 

Classification justification according to CLP

Based on the data above, decan-1 -ol, ethoxylated, 1-2.5EO (CAS 26183-52-8) is considered rapidly biodegradable. The acute aquatic toxicity L(E)C50 is < 1 mg/L for algae and Daphnia. Based on QSAR calculations the lowest expected long-term effect value is 2.92 mg/L Therefore, decan-1 -ol, ethoxylated, 1-2.5EO (CAS 26183-52-8), needs to be classified and labelled as environmental hazard Acute Cat. 1 according to the Regulation (EC) No. 1272/2008 (CLP) and all further amendments.

 

M-factor for acute aquatic toxicity: 1

M-factor for chronic aquatic toxicity: no factor assigned
