Applications and Uses of Silicon Dioxide

Silicon Dioxide E551 can be used in Food, Beverage, Pharmaceutical, Health & Personal care products, Agriculture/Animal Feed/Poultry. Silicon Dioxide is used as a flow agent in powdered foods, or to absorb water in hygroscopic applications. Silicon Dioxide is often used in cheese, fat spreads, confectionery, dried vegetables, etc.

It is necessary for healthy bones, skin, hair and nails. Silicon dioxide is often added to processed foods to keep them fresh and appetizing.

Silicon Dioxide E551 is a dioxide of silicon with the chemical formula SiO2. Silicon Dioxide is used as a anti-caking agent, carrier, and dispersant that can absorb 120% of its weight and remain a free flowing substance. It is used in a wide variety of products such as salt, flour, powdered soups, coffee, vanilla powder, baking powder, dried egg yolk, and tortilla chips.

Silicon Dioxide E551 uses as follows:

Silicon Dioxide

In Food

Silicon Dioxide E551 can be used as flow agent in food such as in cheese, fat spreads, confectionery, dried vegetables.

In Beverage


In Pharmaceutical

Silicon dioxide E551 maintain the strength and density of bones, thus reducing the risk of diseases like arthritis and osteoarthritis in pharmaceutical.

In Health and Personal care

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.

In Agriculture/Animal Feed/Poultry

Silicon Dioxide E551 can be used as Carriers, adsorbents, anti-caking agents and stabilizers in Agriculture/Animal Feed/Poultry feed.

In Other Industries

Silicon Dioxide E551 in the form of sand is used as the main ingredient in sand casting for the manufacture of a large number of metallic components in engineering and other applications. The high melting point of silica enables it to be used in such applications.
