Trimethylated Silica/Dimethicone
What is Trimethylated Silica/Dimethicone?
Trimethylated Silica/Dimethicone combines silica particles, chemically modified with trimethylsilyl groups for water repellency, and dimethicone, a lightweight silicone fluid. Silica originates from abundant silicon dioxide, processed synthetically into fine, hydrophobic spheres. Dimethicone contributes emollience and spreadability. Primarily used in color cosmetics such as foundations, powders, and primers within the makeup category, it acts as a bulking agent to add volume, a slip modifier for effortless application, and an oil adsorbent to reduce shine. This dual structure ensures products glide smoothly, resist clumping, and maintain a matte finish, improving overall wearability and skin feel without heaviness.
