What is it?
Potassium phosphate is a versatile ingredient used in skincare formulations primarily as a pH adjuster and buffering agent. It is a salt that consists of potassium and phosphate ions, and it plays a crucial role in maintaining the stability and efficacy of cosmetic products by regulating their acidity or alkalinity. Potassium phosphate ensures that skincare products remain gentle on the skin while maintaining their intended performance.
Where does it come from?
Potassium phosphate is produced through the neutralization of phosphoric acid with potassium hydroxide. This process yields a stable salt that is commonly used in various industries, including food, pharmaceuticals, and cosmetics. In skincare, it is prized for its ability to maintain the ideal pH balance of formulations, which is essential for both the stability of the product and the health of the skin.
