General Silica powder for toothpaste,purity>99%

The type of silica, which integrates thickening and friction properties, has a thickening effect, high cleaning ability without wearing teeth, and also has high transparency, excellent performance, and can simplify the process and reduce costs.

• It has high fluorine compatibility and can be widely used in various fluoride toothpastes;

• It has good compatibility with other toothpaste components such as flavors;

• It integrates water absorption, thickening and friction cleaning performance, with high cleaning and low wear performance, and high transparency; in the toothpaste formula, a certain proportion of the amount of silica can be reduced, eliminating the need for different types of silica It simplifies the production process and reduces the cost of toothpaste.

Friction performance: copper loss value is 2.5-4 mg; Ra value is 0.15~0.3 μm; RDA value is 90-140; PCR value is 90-120.

Transparency: The refractive index is 1.435-1.460, and the light transmittance is ≥80%.

Application: it can be used as a friction agent and thickener at the same time, used in toothpastes with medium to high friction cleaning value or transparency. Due to its soft shell, it has lower tooth wear than other abrasive silicas on the market, while retaining excellent cleaning effects.

Using: Use 15%-20% alone in the toothpaste formula, without compounding with thickening silica.


Storage recommendations: store in a cool and ventilated warehouse; moisture-proof; avoid direct sunlight; sealed packaging.
