Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Classification related key information

Biodegradation in water: screening tests: 85.2% (ThCO2) in 28 days (OECD 301B) (read-across)

Bioaccumulation: Low bioaccumulation potential expected (see IUCLID section 5.3.1 for details)

Acute toxicity:

- to fish: LC50 (96 h) = 0.37 mg/L for Brachydanio rerio (OECD 203)

- to aquatic invertebrates: EC50 (48 h) = 1.4 mg/L for Daphnia magna (OECD 202)

- to algae: ECr50 (72 h) = 6.3 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) = 0.91 mg/L for Desmodesmus subspicatus (OECD 201) (read-across)

 

Classification justification according to CLP

Based on the data above, Reaction products of oleoyl sarcosine with sodium hydroxide is considered rapidly biodegradable and has a low bioaccumulation potential. The acute aquatic toxicity EC50 value is < 1 mg/L for fish. Valid chronic toxicity data for fish and crustacea are not available. The NOEC for the algae Desmodesmus subspicatus is 0.91 mg/L, based on results from the structurally related substance (Z)-N-methyl-N-(1-oxo-9-octadecenyl) glycine (CAS 110-25-8). Reaction products of oleoyl sarcosine with sodium hydroxide needs to be classified as environmental hazard Acute Cat. 1 and Chronic Cat. 3 according to the Regulation (EC) No 1272/2008 (CLP) and the Regulation (EU) No 286/2011 (2nd ATP).

M-factor for acute aquatic toxicity: 1

M-factor for chronic aquatic toxicity: no factor assigned

  

Classification justification according to DSD

Based on the data above, Reaction products of oleoyl sarcosine with sodium hydroxide is considered to have low potential for bioaccumulation and is rapidly degradable. The acute aquatic toxicity EC50 value is < 1 mg/L for fish. Therefore, Reaction products of oleoyl sarcosine with sodium hydroxide needs to be classified as environmental hazard R50 according to the Directive 67/548/EEC.
