Key value for chemical safety assessment

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.
