SILICON/TITANIUM/CERIUM/ZINC OXIDES

Description

Silicon, titanium, cerium, and zinc oxides are versatile inorganic compounds widely used in skincare and cosmetic formulations. These mineral-based ingredients serve multiple functions, primarily as physical sunscreens and pigments. Silicon dioxide, also known as silica, acts as an absorbent and thickening agent. Titanium dioxide and zinc oxide provide broad-spectrum UV protection by reflecting and scattering both UVA and UVB rays. Cerium oxide, less common but emerging in skincare, exhibits antioxidant properties and potential photoprotective benefits.

These oxides are prized for their stability, non-irritating nature, and suitability for sensitive skin. Titanium dioxide and zinc oxide, in particular, are considered safer alternatives to chemical sunscreens. They remain on the skin's surface, reducing the risk of systemic absorption. Micronized and nano-sized particles of these oxides have improved their cosmetic elegance, minimizing the white cast often associated with mineral sunscreens.

In addition to sun protection, these oxides contribute to product texture, opacity, and color correction in various formulations. They're found in foundations, powders, and other color cosmetics, providing coverage and a matte finish. Their inert nature makes them suitable for a wide range of skin types and conditions.
