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): 0.423 mg/L (TWM, OECD 203)
- aquatic invertebrates: EC50 (48h): 0.125 mg/L (TWM, OECD 202)
- algae: ErC50 (72h) = 0.0445 mg/L (meas. geometric mean, OECD 201)
Chronic toxicity:
- fish: EC10 (28d): 0.251 mg/L (AE specific QSAR)
- aquatic invertebrates: EC10 (21d): 0.054 mg/L (AE specific QSAR)
- algae: ErC10 (72h): 0.0340 mg/L (meas. geometric mean, OECD 201)
Classification justification according to CLP
Alcohols, C12-14, ethoxylated is rapidly biodegradable and has a low potential for bioaccumulate. Based on the data above Alcohols, C12-14, ethoxylated needs to be classified and labelled as Acute Cat. 1 (H400) and Chronic Cat. 2 (H411) for environmental hazards according to the consolidated version of Regulation (EC) No 1272/2008 and further amendments (ATPs).
M-factor for acute aquatic toxicity: 10
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
