SODIUM HEXAMETAPHOSPHATE
Description
Sodium hexametaphosphate (SHMP) is a versatile inorganic compound widely used in skincare formulations and cosmetic products. This water-soluble polyphosphate salt serves multiple functions in personal care applications, primarily as a chelating agent and emulsifier.
SHMP effectively binds to metal ions, preventing them from interfering with product stability and performance. This chelating property is particularly beneficial in hard water environments, where it helps maintain the efficacy of cleansing agents. In skincare formulations, SHMP enhances the preservation system by sequestering metal ions that could otherwise promote microbial growth or product degradation.
As an emulsifier, SHMP aids in the dispersion of oils and waxes in water-based products, contributing to improved texture and stability. It also functions as a mild buffering agent, helping to maintain optimal pH levels in formulations.
SHMP exhibits gentle exfoliating properties, assisting in the removal of dead skin cells and promoting a smoother skin texture. Its ability to soften water makes it valuable in cleansing products, enhancing lather formation and rinsability.
While generally considered safe for cosmetic use, SHMP should be used at appropriate concentrations to avoid potential irritation in sensitive individuals.
