Read-across approach
In the assessment of the toxicity of potassium adipate, a read-across approach from data for adipic acid (CAS 124 -04 -9; EC 204 -673 -3) is followed.
Once the individual constituents of the metal carboxylate become bioavailable (i.e. in the acidic environment in the gastric passage or after phagocytosis by pulmonary macrophages), the “overall” toxicity of the dissociated metal carboxylate can be described by the toxicity of the “individual” constituents. Since synergistic effects are not expected for this group of metal carboxylates, the human health hazard assessment consists of an individual assessment of the metal cation and the organic anion.
As potassium is the eighth or ninth most common element by mass (0.2%) in the human body (an adult of 60 kg adult contains a total of about 120 g of potassium), intake of potassium adipate is not expected to increase significantly the concentration in the human body.
Therefore hazard information was only considered from adipic acid. This information was obtained from existing REACH registration dossiers via a license-to-use obtained by the lead registrant. These registration dossiers were submitted to ECHA in 2010 as full registration dossiers, and are thus considered to contain relevant and reliable information for all human health endpoints. All lead-registrant dossiers were checked for completeness and accepted by ECHA, i.e. a registration number was assigned.
Based on the above information, unresistricted read-across is considered feasible and justified.
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.
