PENTAPOTASSIUM TRIPHOSPHATE

Description

Pentapotassium triphosphate (PKTP) is an inorganic compound with the chemical formula K5P3O10. It belongs to the family of polyphosphates and is widely used in various skincare and cosmetic formulations. This water-soluble salt acts as a chelating agent, sequestering metal ions to enhance product stability and efficacy.

In skincare applications, PKTP serves multiple functions. Primarily, it acts as a buffering agent, helping to maintain the optimal pH balance of formulations. This is crucial for preserving product integrity and ensuring compatibility with the skin's natural pH. Additionally, PKTP exhibits water-softening properties, which can improve the texture and feel of skincare products.

As a chelating agent, PKTP helps prevent the degradation of other ingredients by binding to metal ions that could otherwise catalyze oxidation reactions. This property extends the shelf life of products and maintains their effectiveness over time. PKTP also contributes to the overall cleansing efficacy of skincare formulations by enhancing the removal of impurities and mineral deposits from the skin surface.

While generally considered safe for cosmetic use, it's important to note that PKTP is primarily used in rinse-off products due to its high water solubility.
