Dicalcium Sodium Borosilicate
What is Dicalcium Sodium Borosilicate?
Dicalcium Sodium Borosilicate is a synthetic inorganic compound composed of calcium, sodium, and boron oxides fused with silica, forming smooth, spherical glass microbeads used in skincare products. It functions primarily as a bulking agent, opacifier, and visual texture enhancer, providing a soft-focus effect that blurs fine lines and imperfections while adding a silky feel to formulations. These particles are engineered to be larger than pores, preventing absorption into the skin.
Roles in Formulation
This ingredient serves the following purposes in cosmetic formulations:
Bulking agent
Increases mass/volume to build structure and improve handling, commonly used to adjust feel, spread, and cost-in-use without acting as a primary active.
Pearlescent
Creates a pearly, shimmering appearance by scattering and reflecting light, commonly using mica-based or coated pigments for visual effect.
Opacifying agent
Makes a formula less transparent to create a creamy, opaque look; can also help visually mask suspended particles and improve aesthetic uniformity.
