Anti-caking

Anti-Caking Agents & Moisture Control

Mineral-based anti-caking agents protect bulk powders from humidity and handling stress - maintaining flow, preventing clumps, and preserving quality in storage and transit. Our high-performance desiccants and carriers are used across food ingredients, supplements, fertilizers, and chemical formulations where product integrity and shelf life are critical.

Where They’re Used

Food & nutraceuticals: Keep powdered ingredients and blends free-flowing during mixing, filling, and packaging.
Fertilizers & ag powders: Reduce moisture pickup and clumping in hygroscopic materials.
Chemical formulations: Improve handling and dosing accuracy for fine powders and premixes.
Logistics & storage: Maintain flowability through humidity swings and long-haul transit.

Benefits

Moisture binding & surface adsorption: Controls water activity at particle surfaces to prevent bridging.
Improved flow index: Reduces friction and cohesion, enabling consistent filling and dosing.
Shelf-life protection: Helps limit caking and microbial risk tied to excess moisture.
Process reliability: Fewer stoppages, cleaner hoppers, and more uniform blends.

Example Application

A seasoning manufacturer experiencing clumping during summer humidity added precipitated silica at 1–2% w/w to a salt-based blend. Flow index improved from “poor” to “good,” downtime from hopper blockages fell by 60%, and filling weight variability tightened by 25% over 30 days of warehouse storage.
