Amorphous Hydrated Silicon Dioxide for Oral Care
PRODUCT DETAILS
1. Product Advantages
This product is oral-care-dedicated amorphous hydrated silicon dioxide, produced via a high-purity precipitation synthesis process, featuring a non-crystalline amorphous microstructure and strictly conforming to GB/T 32673-2016 and FDA oral-raw-material authoritative standards. Unlike crystalline silica, this product has no crystalline residue, is non-irritating and offers higher safety. Its loose, porous microstructure and excellent specific surface area combine physical mild abrasion, adsorptive decontamination and thickening/paste-stabilizing performance. With a purity of ≥98.8%, extremely low heavy-metal and impurity residues, and inert and stable chemical properties, it does not react with various active ingredients in toothpaste. The powder has excellent dispersibility.

3. Application Scenarios
Widely used in high-end transparent toothpaste, gel toothpaste, medical oral-care products, maternal-and-infant safe toothpaste and light-luxury functional toothpaste. The pure amorphous structure poses no crystalline hazard, with safety far exceeding ordinary crystalline silica raw materials. Its loose and porous structure efficiently adsorbs soft plaque and pigments on the tooth surface while optimizing the transparent texture of the paste, giving transparent toothpaste a clear color and premium feel. It suits mid-to-high-end branded products with high requirements for raw-material safety, paste aesthetics and usage mouthfeel, and is the mainstream choice for high-end oral-care raw materials.
4. Factory Strength
The company possesses a dedicated synthesis process for amorphous hydrated silica, with crystallinity strictly controlled throughout to ensure 100% amorphous non-crystalline structure, eliminating crystalline-impurity risk at the source. Equipped with X-ray diffractometers and microstructure detectors, it verifies powder structure batch by batch to ensure stable and uniform product structure. A dedicated dust-free production line handles mass production, with extreme control over impurities and heavy metals, giving the product a high safety level. It meets the compliant production of global high-end oral products and can supply stably over the long term.
5. Shipping & Packaging
- Standard packaging: 10 kg / 15 kg food-grade sterile dedicated packaging, free of crystalline contamination risk.
- Moisture-proof design: double-layer sealed moisture-proof protection stabilizes the powder hydrated structure and microscopic morphology.
- Storage & transportation: store sealed in cool, dry and shaded conditions to prevent structural changes; shelf life: 24 months.

6. FAQs
Q: What advantages does the amorphous structure offer over ordinary silica?
A: No crystalline impurities, higher safety, better paste transparency, no sharp crystalline particles, gentler cleaning, and suitability for high-requirement scenarios such as high-end transparent toothpaste and maternal-and-infant toothpaste.
Q: Will structural changes occur during long-term storage?
A: No. The product's hydrated structure is stable. Under sealed storage and transport conditions, there is no crystallization, structural change or performance degradation within the 24-month shelf life.
Q: Is it compatible with transparent gel toothpaste formulations?
A: Highly compatible. The amorphous powder structure has good light transmittance, delivering high transparency after mixing into the paste, with no turbidity, whitening or particle precipitation issues.
