Aluminum Calcium Sodium Silicate

What is Aluminum Calcium Sodium Silicate?

Aluminum Calcium Sodium Silicate is a synthetic inorganic compound formed from aluminum, calcium, sodium, and silicate elements, resembling layered clay minerals. Produced through controlled chemical processes, it serves primarily in color cosmetics, powders, foundations, and creams. As a multifunctional ingredient, it acts as a bulking agent by increasing product volume and density, improving handling and application. It also functions as an absorbent to manage excess oils, a viscosity controller to adjust thickness, and an opacifier for better coverage. In formulations, it contributes to a smooth, matte finish, enhances stability, and optimizes sensory attributes like spread and payoff without adding weight or greasiness, making it ideal for lightweight, buildable textures in makeup and skincare hybrids.
