Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Fatty acids, C8-10, zinc salts:

Toxicity studies of fatty acids, C8-10, zinc salts are not available. Read-across to the assessment entities soluble zinc substances and fatty acids (C8-10) is applied since zinc cations and fatty acid anions (C8-10) determine its fate and toxicity in the environment. Please refer to the respective assessment entity for further details.

Fatty acids (C8-10):

Fatty acids as contained in plant and animal tissue are a natural component of soil, represent a significant part of the nutritional demands of living organisms, are rapidly degraded and non-bioaccumulative and are therefore assumed to be of low toxic potential towards terrestrial arthropods.


Twenty-four NOEC/EC10 values are available for toxicity of Zn to reproduction of terrestrial arthropods, representing 2 different species and ranging between 14.6 and 1000 mg Zn/kg dw (both for Folsomia candida).
