Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
In the assessment of fatty acids, C6-19-branched, calcium salts, calcium salts, read-across to the assessment entities soluble calcium substances and C6-19-branched fatty acids (or rather its structural analogue neodecanoic acid) is applied since the ions of fatty acids, C6-19-branched, calcium salts determine its fate and toxicity in the environment. Calcium is an essential macronutrient for algae and cyanobacteria, a component of all aquatic algae test media (OECD TG 201, 2006) and has a very low potential for toxicity. The toxicity of neodecanoic acid (i.e. the structural analogue of C6-19-branched fatty acids) was evaluated in freshwater, yielding a 72-h EL50 of >100 mg/L for the inhibition of growth of P. subcapitata. Thus, fatty acids, C6-19-branched, calcium salts has a low potential for toxicity to aquatic algae.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
