Precipitated Silica As Abasive Agent in Toothpaste
Product:Silicon Dioxide/silica powder/silica
CAS. NO.:7631-86-9
Item No.:JS-80
Application:for toothpaste as abrasive
The role of precipitated silica in the production of toothpaste abrasives and its characteristics are highly important. Precipitated silica is typically used in toothpaste abrasives due to its low oil absorption and low specific surface area, which help improve the product's texture and consistency.
Moreover, precipitated silica is highly stable and does not react with other components found in toothpaste, such as fluoride, herbals and fragrances, offering the best compatibility. Toothpaste abrasives made from precipitated silica have been proven to be safe and non-toxic food additives and pharmaceutical excipients in many countries worldwide.
Due to its stable chemical properties, precipitated silica does not interact with human saliva or gastric acid, making it very safe for human consumption. These unique properties of precipitated silica make it an excellent and highly effective component in the production of toothpaste abrasives that are both effective and safe to use.
In summary, the use of precipitated silica in toothpaste abrasives has many benefits in terms of stability, safety and effectiveness, and it is an integral part of the production process of many popular dental care products globally. Its use is expected to continue to grow, driven by the increasing demand for safe, high quality and effective dental hygiene products that are both good for our teeth and overall health.
