ZLDIO-T103 Toothpaste Grade Thickening Silica
Product Core Overview
ZLDIO-T103 is a fully self-developed precipitated silica exclusively designed for thickening applications in toothpaste formulations by Zhongqi (Shandong) Silicon Materials Co., Ltd. This product is engineered in strict accordance with the technical requirements for thickening-type products specified in QB/T 2346-2015 Oral Care Products - Silica for Toothpaste, serving as a core rheology modifier, thickening agent, and suspension stabilizer in toothpaste systems.
It complies with QB/T 2346-2015 industry standard, and simultaneously meets the requirements of GB 8372-2023 Toothpaste (National Mandatory Standard), Safety and Technical Standards for Cosmetics (2015 Edition), GB 25576-2020 National Food Safety Standard - Food Additive Silicon Dioxide, as well as international mainstream standards including FCC and USP. Characterized by exceptional water absorption, high oil absorption value, superior light transmittance, matched refractive index, and excellent thixotropy, its measured core indicators far exceed standard limits. It precisely addresses the core needs of toothpaste systems for thickening, shaping, and functional ingredient suspension. Safe and gentle when used within the compliant dosage range, it is fully compatible with the regulatory production requirements of both domestic and export oral care products.
Core Functions and Adaptable Application Scenarios
Core Functions
• Efficient Thickening and Precise Paste Forming: With its high-porosity microstructure, high water absorption and oil absorption values, it rapidly adjusts the viscosity of toothpaste systems, endowing the paste with excellent standing property, formability and fineness. It effectively solves industry pain points such as paste thinning, collapse, water separation and layering, and can flexibly adapt to toothpaste formulas with different hardness and thixotropic requirements.
• Superior Thixotropy for Optimized Production and User Experience: It imparts typical shear-thinning characteristics to toothpaste systems. High locking viscosity at rest ensures long-term paste stability, while low viscosity during extrusion and brushing allows easy spreading without caking. It is perfectly compatible with high-speed automatic filling processes and significantly enhances consumers' brushing experience.
• Long-Lasting Suspension and Full-Cycle System Stability: Its high adsorption property can uniformly suspend functional components in toothpaste systems, including abrasive powders, fluorides, probiotics, desensitizing agents, whitening particles, and plant essential oils/extracts. It prevents sedimentation, layering and oil-water separation during long-term storage, ensuring consistent paste quality and efficacy throughout the entire shelf life.
• High Light Transmittance for Transparent Toothpaste Systems: With a measured light transmittance of 97.1% and a refractive index precisely matched to humectant systems such as glycerin and sorbitol commonly used in toothpaste, it is a core dedicated auxiliary for preparing transparent/semi-transparent crystal toothpaste. It does not affect the transparency and appearance texture of the paste, achieving a balance between high transparency and excellent thickening effect.
• Mild Safety and Strong Regulatory Compliance: Featuring an amorphous structure, neutral pH value and extremely low harmful residues, it causes no abrasion to tooth enamel and is mild and non-irritating to oral mucosa. All microbial indicators meet standards with no pathogenic bacteria detected. It complies with dual regulatory requirements for toothpaste and cosmetics, and does not alter the original flavor and efficacy characteristics of toothpaste when used within the recommended dosage range.
Core Adaptable Application Scenarios
• Core Adaptation: All categories of toothpaste systems
○ Transparent/semi-transparent crystal toothpaste and high-transparency functional toothpaste;
○ Children's toothpaste and mild low-abrasion toothpaste for sensitive teeth;
○ Functional toothpaste: fluoride anti-caries toothpaste, desensitizing toothpaste, probiotic toothpaste, whitening toothpaste, traditional Chinese medicine gum care toothpaste, essential oil fragrance toothpaste, etc.;
○ SLS-free/low-foam toothpaste, fluoride-free toothpaste and swallowable toothpaste;
○ Pump-type toothpaste and travel-sized portable toothpaste.
• Other oral cleaning and care products
○ Oral care gels, tooth whitening strip essence gels and teeth whitening gels;
○ Tooth cleaning powders and scaling powders;
○ Essential oil mouthwashes and antibacterial oral fresheners (for suspending functional ingredients and plant essential oils);
○ Denture cleaning products and oral care effervescent tablets.
Product Core Advantages
• Full Compliance with Standards, Core Performance Far Exceeding Requirements: The product strictly implements the exclusive standard QB/T 2346-2015 for silica for toothpaste. All sensory, physicochemical and hygiene indicators meet standard requirements. Key indicators such as whiteness, water absorption, oil absorption value, light transmittance, heavy metal residues and microorganisms have measured values far exceeding standard limits. With strict quality control standards, it can perfectly meet the quality requirements of high-end oral care products.
• Exclusive R&D for Thickening Applications with Excellent Formula Compatibility: Prepared using an exclusive refined precipitation process for toothpaste thickening silica, its core indicators are designed specifically for toothpaste thickening scenarios. It can adapt to various toothpaste formula systems including hydrated, non-hydrated and transparent types. It can complete selection and adaptation without major adjustments to customers' existing mature production processes, helping customers optimize supply chain costs and supply stability.
