Mechanism of Action
In cosmetic products, Trimagnesium Phosphate primarily operates as an anticaking agent, which helps maintain the free-flowing nature of powdered formulations. It also functions as a bulking agent, contributing to reduced product density and desired texture. Furthermore, its opacifying properties help decrease the transparency or translucency of a product by imparting a cloudy appearance.
