TETRAPOTASSIUM PYROPHOSPHATE

Description

Tetrapotassium pyrophosphate (TKPP) is a versatile inorganic compound widely used in skincare formulations and cosmetic products. This water-soluble salt is derived from pyrophosphoric acid and potassium hydroxide, resulting in a white, crystalline powder. TKPP functions primarily as a chelating agent, sequestering metal ions to prevent unwanted reactions and maintain product stability.

In skincare, TKPP plays a crucial role in pH adjustment and buffering, helping to maintain optimal acidity levels in formulations. This property is particularly beneficial in cleansers and exfoliants, where it can enhance the efficacy of active ingredients. TKPP also exhibits mild surfactant properties, aiding in the removal of dirt and oil from the skin's surface.

The ingredient's ability to soften water makes it valuable in improving the lathering and rinsing capabilities of cleansing products. Additionally, TKPP can act as an emulsion stabilizer, contributing to the texture and consistency of creams and lotions. Its low irritation potential makes it suitable for use in a wide range of skincare products, including those formulated for sensitive skin.

While generally recognized as safe for cosmetic use, TKPP should be used at appropriate concentrations to avoid potential skin dryness or irritation.
