INCI: Silica

What is Silica?

Silica or silicon dioxide is one of the most abundantly found minerals on the Earth's crust. Silica occurs as quartz, the most common component of sand. It also occurs in sandstone, clay, granite, and in parts of plants and animals. It is colorless to white and soluble in water. It has a wide variety of industrial applications, such as food additives, making glass, and in pharmaceuticals.

Use & Benefits:

Abrasive: gently exfoliates the skin, scrubbing off dirt, excess oil, and other impurities, protecting it from infections.

Absorbent: helps absorb excess oil and moisture, making it useful in oil-controlling formulations.

Anti-caking: prevents caking of the product.

Bulking: adds bulk to formulations, making it an ideal ingredient for dry formulations such as powder-based products.

Opacifying: helps reduce the transparency of formulations, making it useful in products that require a more opaque appearance.

Viscosity-controlling: controls the thickness of the solution, making it less runny and easier to spread.
