Sustainable Development

Sustainable processes cut waste, lower emissions, and save costs.

Specialty Solutions

Tailored fine chemicals that enhance efficiency and outcomes.

Chemical Manufacturer

A trusted manufacturer capable of stable, high-volume production and supply.

ABOUT THE PRODUCT

Product Description

Product Description-SILICA CAS#10279-57-9


Hydrated silica, also known as silicon dioxide hydrate or "white carbon black" with the formula SiO₂·nH₂O, is a silicon dioxide-based inorganic chemical material produced via industrial processes such as chemical precipitation. Typically appearing as a white, amorphous, lightweight and odorless powder that is insoluble in water, heat-resistant and non-flammable, it is commonly used as an abrasive in toothpaste to remove soft plaque and extrinsic stains from tooth surfaces through mechanical friction. Its smooth, fine particles have a low Relative Dentin Abrasivity (RDA) value, enabling effective cleaning while helping minimize potential damage to tooth enamel.

Product Applications-SILICA CAS#10279-57-9


Hydrated silica is the main abrasive ingredient in transparent and translucent toothpaste formulations, featuring low abrasivity, excellent fluoride compatibility and widely adjustable performance, and is also commonly used as an abrasive in toothpastes for adolescent oral care. It serves as gentle exfoliating particles in facial and body scrubs for the cosmetics industry, and finds industrial applications as a filler for paints and coatings, a rubber reinforcing agent, a thickening or thixotropic agent for plastics, and a thickener for synthetic greases including silicone grease, while also being an ingredient in various household and personal care products such as dishwashing detergents.
