PRODUCT DETAILS
1. Product Advantages
Custom-developed silica exclusively for fluoride-free toothpaste, this product is engineered for fluoride-free, natural and maternal-infant oral care products, complying strictly with GB/T 32673-2016 and international standards for fluoride-free raw materials.
Adopting a high-purity inert formula, it contains no fluoride ions and leaves no fluoride residues, with silicon dioxide content reaching ≥99%. Heavy metals and impurities are stringently controlled. It has excellent compatibility with core ingredients for fluoride-free toothpaste, such as hydroxyapatite, plant extracts and probiotics.
Its stable powder structure avoids adsorption or antagonism against active fluoride-free repairing ingredients, enabling full performance of enamel remineralization. The RDA value can be customized precisely within the full range of 40–120 to balance gentle cleaning and daily dental protection. It features outstanding paste forming performance and excellent high & low temperature stability without delamination, serving as the core dedicated raw material for high-end fluoride-free toothpaste and natural herbal toothpaste.

3. Application Scenarios
It is specially applicable to all types of fluoride-free toothpaste, primarily used for high-end categories including maternal & infant fluoride-free toothpaste for dental protection, hydroxyapatite remineralizing toothpaste, natural botanical toothpaste, probiotic care toothpaste and pregnancy-specific toothpaste.
Its zero-fluoride characteristic perfectly matches the safe & natural positioning of finished products. It will not interfere with the repairing, bacteriostatic and remineralizing effects of fluoride-free toothpaste. It gently removes dental plaque and stabilizes paste texture, meeting oral care demands of sensitive teeth groups, children, pregnant women and other special crowds, making it an essential raw material for premium fluoride-free oral care products.
4. Factory Strength
Our company has an exclusive fluoride-free silica production system and independent dust-free workshops. Fluoride contamination is isolated throughout the whole manufacturing process to guarantee zero fluoride residues.
Equipped with ion precision detectors and high-purity composition analyzers, we conduct batch-by-batch inspection on fluoride content and purity to ensure 100% compliance of fluoride-free requirements.
With over 20 years of R&D experience in the silica industry, we optimize powder structures to fit diverse fluoride-free formula systems. 26 comprehensive inspection procedures eliminate batch differences.
Our 10,000-ton annual dedicated production lines ensure stable supply. Our products have obtained international fluoride-free raw material certifications and are exported to high-end natural oral care markets in Europe, America, Japan and South Korea.

6. Frequently Asked Questions
Q1: Is this fluoride-free silica completely fluoride-free?
A: Yes. It is produced via a full fluoride-free process with fluoride ion content fixed at 0 ppm and no fluoride residues. It fully meets domestic and international manufacturing standards for fluoride-free toothpaste, and can be safely applied to maternal, infant and pregnancy-use oral products.
Q2: Will it weaken the remineralization effect of hydroxyapatite?
A: It will not. Extremely inert in chemical properties, the silica neither adsorbs nor counteracts hydroxyapatite. Instead, it helps strengthen adhesion on tooth surfaces and facilitates enamel repair and remineralization.
Q3: Is this silica universally applicable for all fluoride-free toothpaste formulas?
A: Yes. It is compatible with all fluoride-free toothpaste varieties. We can customize abrasion grades with different RDA values according to product positioning, matching application scenarios for children, sensitive-teeth users, adults and more.
