Potassium Sulfate
What is Potassium Sulfate?
Potassium sulfate, chemically K₂SO₄, is an inorganic salt formed from potassium and sulfate ions, appearing as a white, water-soluble powder. In cosmetics, particularly hair care like shampoos and conditioners, and some skincare items, it acts to regulate product consistency. By altering flow properties, it stabilizes emulsions, suspends particles uniformly, and optimizes dispensing from containers. This results in reliable performance and appealing sensory qualities without influencing color, fragrance, or biological interactions. Synthetically produced to high purity standards, it suits rinse-off and select leave-on formulas. Authoritative assessments highlight its minimal reactivity, making it a dependable choice for formulators aiming for practical, user-friendly textures across diverse product types.
