Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Conclusion on classification

Classification related key information

Biodegradation in water: screening tests: 82% (ThCO2) in 28 days (ISO 14593) (read-across)

Log Kow: 4.1 (KOWWIN v1.67)

Acute toxicity

- to fish: LC50 (96 h) = 107 mg/L for Danio rerio (OECD 203) (read-across)

- to aquatic invertebrates: EC50 (48 h) = 29.7 mg/L for Daphnia magna (OECD 202) (read-across)

- to algae: ECr50 (72 h) = 79 mg/L, for Desmodesmus subspicatus (OECD 201) (read-across)

Chronic toxicity

- to fish: not available

- to aquatic invertebrates: not available

- to algae: NOEC (72 h) = 9.2 mg/L for Desmodesmus subspicatus (OECD 201) (read-across)

 

Classification justification according to CLP

Based on the data above, N-lauroylsarcosine (CAS 97-78-9) is considered rapidly biodegradable. The acute aquatic toxicity EC50 values are in the range from 10 to 100 mg/L for algae and crustacean (> 1 mg/L). Valid chronic toxicity data for fish and crustaceae are not available. The NOEC for the alga Desmodesmus subspicatus is 9.2 mg/L. N-lauroylsarcosine (CAS 97-78-9) is not classified as environmental hazard according to Regulation (EC) No 1272/2008 (CLP) and Regulation (EU) No 286/2011 (2nd ATP).

 

Classification justification according to DSD

Based on the data above, N-lauroylsarcosine (CAS 97-78-9) is considered to have low potential for accumulation as rapidly degradable. The acute aquatic toxicity EC50 values are in the range from 10 to 100 mg/L for algae and crustacea. Therefore, N-lauroylsarcosine (CAS 97-78-9) is not classified as environmental hazard according to Directive 67/548/EEC.
