Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

PNEC for bethic organisms can be calculated applying the equilibrium partitioning method using a Kpsed or Kdsed of 72.5 L/kg (Koc of 1451 L/kg;

Ksusp-water 37.2 m3/m3 - this leads to a PNEC of  4.85 mg a.i./kd dw .

Key value for chemical safety assessment

Additional information

Lauric acid 2-sulfoethyl ester, sodium salt has a low to moderate sorption to soil and is readily biodegradable to CO2 and H2O and NO3. The PNEC sediment is calculated using the equilibrium paritioning method as no short or long-term benthic test data is available for Coco fatty acids 2 -sulfoethyl ester, sodium salt.
