Dipotassium Phosphate

Description

Dipotassium Phosphate is a versatile inorganic compound with the chemical formula K2HPO4. In skincare formulations, it serves multiple functions, primarily as a pH adjuster and buffering agent. This water-soluble salt helps maintain product stability by regulating acidity levels, which is crucial for the efficacy and safety of various skincare ingredients.

As a buffering agent, Dipotassium Phosphate prevents sudden pH changes that could compromise the integrity of the formulation or irritate the skin. Its ability to control pH is particularly beneficial in products containing active ingredients sensitive to pH fluctuations, such as certain vitamins or enzymes.

Additionally, Dipotassium Phosphate acts as a chelating agent, binding to metal ions that could otherwise destabilize the product or reduce its effectiveness. This property enhances the shelf life and overall quality of skincare formulations.

In some products, it may also function as a mild emulsifier, helping to blend oil and water-based ingredients. While generally considered safe for topical use, it's important to note that Dipotassium Phosphate is typically used in small quantities in skincare formulations due to its potent pH-adjusting capabilities.
