SILICON/TITANIUM/CERIUM/IRON OXIDES

Description

Silicon, titanium, cerium, and iron oxides are versatile mineral compounds widely used in skincare and cosmetic formulations. These oxides serve multiple functions, primarily as pigments and UV filters, offering both aesthetic and protective benefits.

Silicon dioxide, or silica, acts as an absorbent and anti-caking agent, improving product texture and stability. Titanium dioxide is a potent UV filter, providing broad-spectrum protection against both UVA and UVB rays. It also imparts opacity and whiteness to formulations. Cerium oxide exhibits antioxidant properties, potentially neutralizing free radicals and reducing oxidative stress on the skin. Iron oxides come in various colors (red, yellow, black) and are essential for creating diverse shades in makeup products while offering some UV protection.

These oxides are generally considered safe for topical use, with low risk of skin irritation or sensitization. They are inert, non-reactive, and do not penetrate the skin, making them suitable for a wide range of skin types. In sunscreens, these compounds often work synergistically to provide effective UV protection without chemical filters. Their stability and non-comedogenic nature make them valuable ingredients in long-wearing, water-resistant formulations.
