Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

The adsorption/desorption study required in REACH guidance, Annex IX (Section 9.3.3) does not need to be conducted as the substance has low potential for adsorption with a partition coefficient of less than zero (log Kow <0).

The adsorption/desorption behaviour of the citrate salts is equivalent to that of citric acid. However, the Chemical Safety Assessment (CSA) has shown that any adsorption/desorption associated with the Koc value of citric acid is insignificant.
