ZLXIDE-P380 Ultra-High Purity Hydrophilic Colloidal Silicon Dioxide
Product Overview
ZLXIDE-P380 represents our highest grade of food-grade colloidal silicon dioxide (E551), developed exclusively for the most demanding applications where safety, purity and performance are non-negotiable. Manufactured in a dedicated ultra-high purity production facility with Class 100,000 GMP cleanroom conditions, this product achieves a minimum purity of 99.2% with ultra-low impurity levels. It is the ideal choice for medical foods, infant formula and organic food products that require the highest level of safety assurance.
Core Functions & Application Scenarios
Key Functional Benefits
1. Exceptional Long-Term Anti-Caking Stability: The ultra-high specific surface area provides maximum particle separation efficiency, ensuring excellent anti-caking performance even for products with extended shelf lives of 24 months or more. This is critical for infant formula and medical foods that require uncompromising quality throughout their lifecycle.
2. Perfect Nano-Scale Dispersion: The precisely controlled ultra-fine particle size ensures complete dispersion without agglomeration, resulting in a smooth, uniform texture with absolutely no gritty sensation. It does not affect the appearance, taste or nutritional value of the final product.
3. Chemically Inert & Nutrient-Safe: Exhibits exceptional chemical stability and does not react with any food ingredients, vitamins, minerals or active pharmaceutical ingredients. This preserves the nutritional integrity and efficacy of sensitive products.
Primary Application Areas
• Food Industry: Infant formula and follow-on formulas, medical foods (FSMP), premium organic foods, high-end nutritional supplements and hypoallergenic food products
• Food-Grade Industrial Applications: High-transparency food-grade silicone rubber, premium food contact coatings, electronic-grade food ingredients
• Other Sectors: Export to top-tier international markets, precision food-grade excipients and pharmaceutical applications requiring the highest purity standards
Product Advantages
1. Engineered for the Most Stringent Applications: Developed to meet the strictest global standards for sensitive food products, ZLXIDE-P380 delivers performance that exceeds industry requirements for medical foods and infant nutrition. It can be directly substituted for other high-purity colloidal silicon dioxide products without process modifications.
2. Uncompromising Purity & Safety: With a minimum SiO₂ content of 99.2% and heavy metal levels far below both Chinese and international limits, our product contains no crystalline silica and is manufactured using only food-grade raw materials. This provides the highest level of safety assurance for vulnerable consumer groups.
3. Ultra-Low Dosage for Clean Label Formulations: The exceptional surface activity allows effective performance at dosages as low as 0.05%, supporting the clean label trend in premium food products. It minimizes the total additive content while maintaining optimal functionality.
4. Global Top-Tier Regulatory Compliance: Certified to the most rigorous international standards including CE, FDA and EFSA E551, our product has been approved for use in all major global markets. We provide complete regulatory documentation to support market access to the EU, North America, Japan, South Korea and Australia.
