ZLXIDE-P972 Hydrophobic Fumed Colloidal Silicon Dioxide
Product Overview
ZLXIDE-P972 is our specialized food-grade hydrophobic colloidal silicon dioxide (E551), manufactured via advanced surface-modified fumed process technology. Unlike hydrophilic grades, this product has been treated with food-grade dimethyldichlorosilane to create a hydrophobic surface, making it highly resistant to moisture. It is the ideal solution for high-humidity environments and products with high oil content that are prone to caking and oil seepage.
Core Functions & Application Scenarios
Key Functional Benefits
1. Superior Hydrophobic Anti-Caking Performance: The chemically bonded hydrophobic surface repels water molecules, providing exceptional anti-caking performance even in high-humidity environments (up to 80% relative humidity). This makes it perfect for products manufactured or stored in tropical and coastal regions.
2. Excellent Organic System Compatibility: Exhibits outstanding compatibility with oils, fats and other organic food ingredients, dispersing uniformly without agglomeration. It improves the stability of oil-based systems and prevents phase separation.
3. Oil Absorption & Anti-Seepage: Effectively adsorbs free oils and fats in high-oil content products, preventing oil seepage through packaging and reducing product stickiness. This maintains product appearance and extends shelf life.
Primary Application Areas
• Food Industry: High-oil content powder products, complex spice blends, baking pre-mixes, instant noodle seasonings, cheese powders and products intended for export to high-humidity tropical regions
• Food-Grade Industrial Applications: Food-grade solvent-based coatings, silicone rubber reinforcement, lubricant thickening
• Other Sectors: Products stored in high-humidity warehouses, export to Southeast Asia, South America and other tropical regions
Product Advantages
1. Optimized for High-Humidity Environments: Engineered to match global industry standards for hydrophobic food-grade anti-caking agents, ZLXIDE-P972 delivers consistent performance in challenging moisture conditions where hydrophilic products fail.
2. Controlled Food-Grade Surface Modification: The dimethyldichlorosilane surface modification process is precisely controlled to ensure uniform hydrophobicity across all particles. The modification materials are food-grade approved and leave no harmful residues.
3. Wide Temperature Range Compatibility: Maintains stable performance across a broad temperature range from -40°C to 200°C, making it suitable for a wide variety of food processing methods including freezing, baking and high-temperature sterilization.
4. Comprehensive Safety Certifications: Manufactured in strict compliance with food safety regulations and certified to FDA, Halal and Kosher standards, ensuring safe use in all food applications.
