Hybrid silicon dioxide Hybrid Silicon Dioxide 1. Product Overview (Product Overview) 1.1 Basic definitions Zhongqi Hybrid Silica, a food-grade functional additive produced through precipitation technology, appears as a white, fine powder. Its core feature lies in achieving dual functions of efficient cleaning and paste stabilization without reacting with fluoride, desensitizers, whitening agents, or other toothpaste components. This integrated additive serves as the essential building block for simplifying multi-functional toothpaste formulations. 1.2 Core values As a dual-purpose additive that balances cleaning and stability, Zhongqi Hybrid Silica effectively addresses industry pain points such as complex formulations, high costs, and poor compatibility caused by traditional toothpaste requiring simultaneous addition of abrasives and thickeners. By precisely regulating the core-shell structure ratio, it achieves a synergistic balance between abrasive performance and thickening effects, catering to diverse scenarios including adult multi-functional toothpaste, travel-ready versions, and herbal medicine applications. This provides toothpaste manufacturers with efficient, cost-effective, and stable formula solutions. 2. Product Characteristics (Product Characteristics) 2.1 Structural and performance advantages •Dual-function structure of nuclear shell: The inner layer of dense particles (particle size 8-14μm) provides 70-100 RDA wear value to meet the basic cleaning needs; the outer layer of loose mesh structure can absorb water and oil, achieving 30-42mL/20g water absorption, and has thickening and suspending effects. •Strong compatibility: pH value 6.5-7.5, excellent compatibility with fluoride, potassium nitrate, plant extracts and other active ingredients, does not affect the release efficiency of fluoride ion (release rate ≥98%), and can adsorb the effective components of Chinese herbal medicine. •High process adaptability: compacted density of 220-280g/L, excellent fluidity (settling angle ≤38°), suitable for high-speed preparation equipment, mixing time reduced to 15 minutes, production efficiency increased by 25%; good plasticity of paste, complete strip after extrusion, no fracture, collapse phenomenon. 3.

Application fields (Application Fields) 4.1 Adult multifunctional toothpaste •The "clean + anti-cavity + mild whitening" three-in-one toothpaste can be adapted to replace the combination of 20-30% abrasive and 3-5% thickener in traditional formula with 18-25% addition, simplify the formula ingredients and reduce the cost of raw materials. 4.2 Travel portable toothpaste •Designed for compact 10-20g travel tubes, this 8-12μμm particle model delivers exceptional flowability and moldability, compatible with high-speed filling systems that maintain filling accuracy within ±2%. The formulation resists temperature fluctuations (-5° to 45°℃), effectively preventing deformation and leakage during transit, while enhancing user experience throughout the journey. 4.3 Toothpaste with Chinese herbal efficacy •As a carrier and stabilizer of Chinese herbal extracts, the 12-16μm porous structure can adsorb baicalin, menthol and other components, which significantly improves the adsorption capacity compared with ordinary excipients, reduces the oxidation and degradation of active ingredients, and covers the bitter taste of herbal medicine. 4.4 Sensitive tooth care toothpaste •Suitable for sensitive toothpaste containing potassium nitrate, the medium and low RDA value of 75-95 reduces dentin wear, the loose outer structure stabilizes the suspension of anti-sensitivity components, the uniformity of paste content RSD <2%, and the active ingredients are released quickly during brushing to relieve sensitivity symptoms. 5. Standards and regulations (Standards & Regulations) Comply with national and industry standards: GB/25576-2020 index requirements. Obtain relevant qualification certification: food additive production license, CMA/CNAS testing certification. Follow the safety specifications: heavy metal and microbial indicators are fully up to standard, total bacterial count is less than or equal to 1000CFU/g, total heavy metal (Pb, As, Hg) is less than or equal to 10ppm, and oral mucosal irritation test results are "no irritation". 6. Product Advantages (PA) •High efficiency of functional integration: "friction + thickening" two in one, reduce the type of auxiliary materials, simplify the formula design and production process, reduce the comprehensive cost of enterprises. •Extensive scene adaptation: it covers various types of toothpaste needs such as multi-function, travel, Chinese herbal medicine, etc., and can adjust the efficacy without changing the auxiliary materials, so as to improve the efficiency of product development. •Safe and reliable performance: medium and low wear value is suitable for sensitive tooth population, strict safety test has been conducted, no risk of oral irritation, suitable for all ages. •Batch stability and controllability: the proportion deviation of core-shell structure is less than 3%, and the fluctuation of key parameters (RDA, water absorption) between batches is less than 5%, so as to ensure the consistency of mass production. 7.
