Additional information
Conclusion on classification
Classification related key information
Biodegradation in water: Readily biodegradable
Bioaccumulation: Alcohol ethoxylates are not expected to bioaccumulate due to a rapid biotransformation and excretion.
Acute toxicity:
- fish: LC50 (96h): 3.732 mg/L (AE specific QSAR)
- aquatic invertebrates: EC50 (48h): 1.213 mg/L (AE specific QSAR)
- algae: ErC50 (72h): 0.919 mg/L (AE specific QSAR)
Chronic toxicity:
- fish: EC10 (28d): 0.896 mg/L (AE specific QSAR)
- aquatic invertebrates: EC10 (21d): 0.312 mg/L (AE specific QSAR)
- algae: ErC10 (72h): 0.498 mg/L (AE specific QSAR)
Classification justification according to CLP
Alcohols, C10-12 (even numbered), ethoxylated (1-2.5 EO) is rapidly biodegradable and has a low potential for bioaccumulate.
Based on the data above Alcohols, C10-12 (even numbered), ethoxylated (1-2.5 EO) needs to be classified and labelled as Acute Cat. 1 (H400) and Chronic Cat. 3 (H412) for environmental hazards according to the consolidated version of Regulation (EC) No 1272/2008 and further amendments (ATPs).
M-factor for acute aquatic toxicity: 1
