Silica for Salt

Product Specification

Feature

Highly effective anticaking agent for salt: Specially engineered porous silica with high oil/moisture adsorption capacity, rapidly absorbs trace moisture in salt crystals and forms a dry, non-hygroscopic coating on particle surfaces, effectively preventing salt caking, bridge formation, and lump formation under high-humidity storage conditions. Superior flowability & free-flow performance: Even at very low dosage levels (typically 0.5%–2.0% by weight), it dramatically improves the pourability and flow characteristics of table salt, seasoned salt, sea salt, rock salt, brine-dried salt, and salt blends, ensuring smooth dosing, packaging, and dispensing. Low addition rate, high cost-efficiency: Optimized pore structure and surface area deliver maximum anti-caking performance at minimal usage level, helping producers reduce formulation cost while maintaining consistent product quality across seasonal humidity fluctuations. Excellent compatibility with salt systems: Chemically inert and stable in high-salinity, high-ionic-strength environments; does not react with sodium chloride, sodium chloride-based seasonings, iodizing agents (KI/KIO₃), anti-caking co-agents, or other functional additives; preserves salt purity, crystal clarity, and taste. Fine particle size & even dispersion: Microfine, readily dispersible powder blends uniformly into salt crystals without visible specks, discoloration, or gritty texture; maintains the natural white appearance and sensory properties of the finished salt product. Broad regulatory compliance: Food-grade quality meeting FCC (Food Chemicals Codex), E551 (EU food additive standard), GB 25576 (China food additive silica standard), and FDA 21 CFR 172.480 requirements; suitable for direct food contact and human consumption applications. Moisture control & shelf-life extension: Protects salt from moisture pickup during transit, warehouse storage, and in-home use (e.g., humid kitchen/bathroom environments), maintaining product free-flowing from first use to last pour; reduces customer complaints about hard clumps. Versatile across salt categories: Suitable for edible table salt, iodized salt, sea salt, Himalayan pink salt, seasoned/spiced salt, bath salts, and industrial salt applications; performs reliably across vacuum-dried, solar-evaporated, and granulated salt production processes. Consistent batch-to-batch quality: Tight control over moisture content, bulk density, particle size distribution, and heavy metal impurities ensures reproducible anti-caking performance and clean labeling compliance. Full technical documentation support: COA, MSDS, FDA/EU/China regulatory dossiers, and application formulation guidelines available; technical team supports customers in dosage optimization, process integration, and scaling up from pilot to full production.
