Sodium Metaphosphate
What is Sodium Metaphosphate?
Sodium metaphosphate is an inorganic sodium salt of metaphosphoric acid, synthesized for use in cosmetics. It falls into oral care and cleansing product categories, where it performs key functions. As a chelating agent, it captures metal ions such as calcium and magnesium, preventing them from causing formulation instability, scaling, or reduced effectiveness. It also serves as a buffering agent, helping to stabilize pH levels for consistent product performance and skin compatibility. In oral care items like toothpastes and mouthwashes, it contributes to hygiene by binding minerals involved in tartar formation, aiding in smoother cleaning action. This compound supports overall product quality, ensuring reliable results in rinse-off and leave-on applications without altering texture or efficacy.
