SODIUM METAPHOSPHATE

Description

Sodium metaphosphate is a versatile inorganic compound widely used in skincare and cosmetic formulations. This white, crystalline powder is composed of sodium and metaphosphate ions, forming a complex structure that contributes to its diverse applications. In skincare, sodium metaphosphate primarily functions as a chelating agent and pH buffer.

As a chelating agent, sodium metaphosphate binds to metal ions in formulations, preventing them from interacting with other ingredients and potentially causing product instability or skin irritation. This property is particularly valuable in products containing minerals or those exposed to hard water. The ingredient also acts as an effective pH buffer, helping to maintain optimal acidity levels in skincare products, which is crucial for preserving their efficacy and ensuring skin compatibility.

Sodium metaphosphate exhibits mild exfoliating properties, assisting in the gentle removal of dead skin cells. Additionally, it can enhance the foaming and cleansing capabilities of personal care products. Its ability to soften water makes it beneficial in formulations designed for use in areas with hard water. While generally considered safe for topical use, as with any ingredient, patch testing is recommended for individuals with sensitive skin or known allergies.
