Description of key information
Key value for chemical safety assessment
Additional information
Potassium and phosphate are abundant in the human body, mainly as electrolytes of the intracellular fluid. Safe intakes can be proposed on physiological levels of these electrolytes.
Phosphate is present in the blood as anorganic phosphate, organic ester and phospholipid.
Potassium is mainly present intracellularly in the body. Extracellular potassium levels are maintained via distal kidney tubuli mechanisms.
As inorganic salts they are expected to be very poorly absorbed through skin.
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.
