Natural silica spheres for soft-focus and mattifying cosmetic finishes

Product Overview

Geosoft® is a range of highly pure, spherical silica microspheres designed to deliver a ball‑bearing effect and sensorial enhancement in cosmetic formulations. The grades provide 100% natural-origin, non‑plastic alternatives to traditional polymer beads, supporting microplastic‑free claims while maintaining excellent performance.

The uniform silica spheres improve spreadability, slip and product payoff while contributing soft‑focus optical diffusion or balanced mattifying effects, depending on the grade. Both grades disperse readily without grinding and are compatible with most cosmetic systems, in water‑ or solvent‑based formulations.
