PRODUCT DETAILS
1. Product Advantages
Our product is toothpaste-grade precipitated silica, commonly known as toothpaste white carbon black within the oral care industry. It fully complies with national standard GB/T 32673-2016 as well as international standards FDA and FCC. It features whiteness ≥96% and silica content ≥98% with ultra-low heavy metal residues, making it the most widely used and cost-effective abrasive and thickener raw material for toothpaste manufacturing.
Chemically inert, it does not react with any toothpaste ingredients including fluorides, flavors, pigments, herbal extracts and other additives, delivering excellent universal compatibility with all toothpaste formula systems.
We supply three product series: abrasive type, thickening type and hybrid type. The RDA value can be precisely customized within the range of 50–200. With uniform particle size distribution and zero coarse particles, the powder leaves no gritty sensation during application, greatly improving the smooth texture and stability of toothpaste paste, suitable for mass production of all toothpaste categories.

3. Application Scenarios
Specially developed for manufacturing all types of toothpaste, our silica fits basic cleaning toothpaste, whitening toothpaste, herbal toothpaste, children’s toothpaste, sensitive toothpaste, transparent toothpaste and more.
- Abrasive Grade Silica: Effectively removes dental plaque and extrinsic stains while protecting tooth enamel, serving as the core abrasive component of toothpaste.
- Thickening Grade Silica: Forms a stable 3D network structure to boost paste viscosity, preventing paste separation and water bleeding under high and low temperatures for long-term formulation stability.
- Hybrid Grade Silica: Combines abrasive and thickening functions in one material, simplifying toothpaste formulas and cutting production costs. This multi-functional universal raw material meets production demands for toothpaste brands across all price tiers.
