Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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, C14 -18 AND C16 -18 -UNSATD., ZINC SALTS:
Based on data on bioaccumulation of zinc in animals and on biomagnification (i.e. accumulation and transfer through the food chain), secondary poisoning with Fatty acids, C14 – C18 and C16-18-unsatd., zinc salts is not considered to be relevant.
ZINC:
zinc is an essential element which is regulated throughout the food chain. It does not bioaccumulate/biomagnify. Therefore testing of long-term toxicity to birds is considered not relevant.
Key value for chemical safety assessment
Additional information
Avian toxicity data are not available neither forFatty acids, tallow, zinc saltsnor for other zinc substances.
As in the EU Risk Assessment Report (RAR) for zinc stearate, it is assumed that after intakeFatty acids, tallow, zinc saltsis changed (at least in part) to ionic zinc and that only ionic zinc is determining biological activities. The conclusions for a similar fatty acid zinc salt from the EU RAR Zinc distearate CAS-No.: 557-05-1 and 91051-01-3; EINECS-No.: 209-151-9 and 293-049-4) Part 1 - Environment (Final report R074_0805_env, May 2008) are as follows: "Based on data on bioaccumulation of zinc in animals and on biomagnification (i.e. accumulation and transfer through the food chain), secondary poisoning is considered to be not relevant in the effect assessment of zinc, see further the RAR Zinc metal." The bioaccumulation of zinc in birds is discussed below.
The conclusions for avian toxicity of zinc apply toFatty acids, tallow, zinc salts as well.
ZINC:
The aim of avian toxicity tests is to provide data for secondary poisoning, if the chemical safety assessment demonstrates the need for such a study (notably relevant for substances with a potential to bioaccumulate and high mammalian toxicity). Zinc is an essential element that is regulated throughout the food chain and does not bioaccumulate/biomagnify. For this reason, the potential for secondary poisoning is not considered relevant (EU risk assessment, ECB 2008), and testing of long-term toxicity to birds is considered not relevant.
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.
