Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key value for chemical safety assessment

Additional information

In accordance with Regulation (EC) No. 1907/2006, Annex X, section 9.4, column 2, further studies on terrestrial organisms do not have to be conducted since the chemical safety assessment indicates that there is no need. The terrestrial toxicity of the Sulfonic acids, C14-16 (even numbered)-alkane hydroxy and C14-16 (even numbred)-alkene, sodium salts has been further tested with the earth-worm Eisenia fetida. No Observed Effect Concentration (NOEC) for mortality and weight changes was determined to be the concentration of 1000 mg test item/kg soil. The No Observed Effect Concentration (NOEC) for reproduction was determined to be the concentration of 316 mg test item/kg soil.

Moreover, the substance is readily biodegradable and shows no inhibition to aquatic microorganisms. Based on the available data, no toxicity of Sulfonic acids, C14-16 (even numbered)-alkane hydroxy and C14-16 (even numbered)-alkene, sodium salts to soil microorganisms is expected. Additionally, the substance is not expected to remain in the terrestrial environment, due to readily biodegradation and low adsorption potential, reducing the potential for chronic exposure.

Based on this information, toxicity to soil microorganisms is not expected to be of concern, and consequently, no further testing is required.
