Stability
A 1% aqueous solution of Pentapotassium Triphosphate exhibits a pH range between 9.2 and 10.5, highlighting its inherent alkalinity and robust buffering capabilities. Its chelating action is crucial for formula stability, as it prevents undesirable interactions caused by free metal ions.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has determined Pentapotassium Triphosphate to be safe under current cosmetic use practices and concentrations. However, due to its mildly alkaline nature, salts of polyphosphate anions, including this one, may lead to moderate irritation of the skin and mucous membranes. GHS classifications indicate a potential for skin irritation in approximately 10.5% of reported cases and serious eye irritation in a similar percentage. It is also found in food products as an additive, with the FDA generally recognizing small amounts of inorganic phosphates as safe for consumption.
