Description of key information

The chemical safety assessment according to Annex I of Regulation (EC) No 1907/2006 does not indicate the need to investigate further toxicity testing with terrestrial organisms.

Additional information

In accordance with Annex IX, column 2 of Regulation (EC) No 1907/2006, toxicity testing with terrestrial organisms does not need to be conducted as the Chemical Safety Assessment according to Annex I of Regulation (EC) No 1907/2006 does not indicate a need for further investigations.

Sodium N-lauroylsarcosinate (CAS 137-16-6) has a low adsorption potential due to a log Pow of 0.37. In addition, the substance is determined to be readily biodegradable indicating a low potential for persistence. Furthermore, the substance is not classified for environmental hazards according to the Regulation (EC) No 1272/2008 (CLP) and following amendments (ATPs).

All available EC/LC50 are > 1 mg/L for algae, daphnia or fish. Thus, according to Guidance on information requirements and chemical safety assessment, R.7c (ECHA, 2017) Sodium N-lauroylsarcosinate (CAS 137-16-6) is in “Hazard category 1”. Therefore, in accordance with Annex IX, column 2 of Regulation (EC) No 1907/2006, in the absence of toxicity data for soil organisms, the equilibrium partitioning method has to be applied to assess the hazard to soil organisms. The PNEC (soil) was derived with the Equilibrium Partitioning Method (EPM) for evaluation of the PEC/PNEC ratio. This screening assessment indicates no risk for the terrestrial compartment (RCR < 1; please refer to Chapter 9 and 10 of the Chemical Safety Report for detailed information). Thus, according to Guidance on information requirements and chemical safety assessment, R.7c (ECHA, 2017), no toxicity testing for terrestrial organisms needs to be done.
