Potassium Citrate
What is Potassium Citrate?
Potassium citrate is the potassium salt of citric acid, derived from citrus fruits or produced synthetically as a white, hygroscopic powder highly soluble in water. In cosmetics, it belongs to the category of functional ingredients used across cleansers, moisturizers, serums, and hair products. It works primarily by regulating pH levels to keep formulations within an optimal range, which preserves ingredient activity, boosts preservative function, and ensures mildness on skin. As a chelating agent, it sequesters trace metal ions from water or raw materials that might catalyze unwanted reactions like discoloration or rancidity. This dual action promotes long-term product stability and consistent performance during use, making it a staple in modern skincare for reliable, user-friendly results without compromising quality.
