This is the most common constituent of sand. Silica, also called silicone dioxide, and Hydrated Silica are minerals. Silica is a compound composed of silicon and oxygen. The amorphous form is used in cosmetics and personal care products. Amorphous Silica includes fumed silica. The Silica used in cosmetics and personal care products is amorphous Silica. This means that the Silica has no definite form. Fine silica, typically used in industrial applications and inhaled by workers, is associated with a wide range of disorders, particularly affecting the lungs and respiratory system. In cosmetics for skin use, regular sand presents little, if any risk to people. In contrast, for products that might be inhaled (such as a facial powder), silica particles are finely ground down and may be associated with respiratory toxicity. Silica and Hydrated Silica are used in a wide range of cosmetics and personal care products including bath products, eye makeup, hair care products, makeup, nail care products, oral hygiene products and skin care products.
