Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Conclusion on classification
The assessment is based on the data currently available. New studies, based on the category review and the final decisions issued for some of the category substances, which are also relevant for this assessment, are currently being conducted. The hazard assessment with respect to aquatic toxicity will be updated once all ongoing studies have been finalised.
Classification related key information
Biodegradation in water: readily biodegradable (category read-across)
Bioaccumulation: low potential for bioaccumulation
Acute toxicity:
- fish: LC50 (96 h): >96 mg a.i./L (TWA, OECD 203; category read-across)
- invertebrates EC50 (48 h): >110 mg a.i./L (nominal, OECD 202; category read-across)
- algae: ErC50 (72 h) > 100 mg a.i./L (nominal, OECD 201; category read-across)
Chronic toxicity:
- invertebrates: NOEC (21 d): 5.3 mg a.i./L (measured, OECD 211; category read-across)
- algae: NOErC (72 h): 31.25 mg a.i./L (nominal, OECD 201; category read-across)
Classification justification according to CLP:
Based on the data above, Alcohols, C8-10, ethoxylated, sulfates, sodium salts is considered to be rapidly degradable and has a low potential for bioaccumulation. The acute and chronic effect concentrations are > 1 mg/L for fish, invertebrates and algae. Based on the data listed above Alcohols, C8-10, ethoxylated, sulfates, sodium salts does not need to be classified and labelled for environmental hazard according to the consolidated version of Regulation (EC) No.1272/2008 (CLP) and further amendments (ATPs).
M-factor for acute aquatic toxicity: -
M-factor for chronic aquatic toxicity: -
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
