Product overview
Sodium Hexametaphosphate (SHMP) is a phosphate ingredient evaluated for buffering, sequestration, moisture retention and texture control. It is commonly evaluated for Mineral sequestration, Beverage and food processing, Water softening and scale control. Supply for food, feed or healthcare use requires the appropriate grade, specification and destination-market compliance review.
Function & Usage
- Retain Moisture & Improve Phosphate Performance
Sequesters minerals, supports dispersion and helps control interactions that affect processing and texture. Typical uses: Mineral sequestration, Beverage and food processing, Water softening and scale control.
- Build Detergency & Remove Soil
Supports wetting, detergency, grease removal, foam or soil suspension in suitable cleaning formulations. Typical uses: Mineral sequestration, Beverage and food processing, Water softening and scale control.
- Chelate Metals & Soften Water
Chelates or sequesters metal ions to support water softening, detergency and process stability. Typical uses: Mineral sequestration, Beverage and food processing, Water softening and scale control.
- Disperse Solids & Control Deposits
Disperses particles or helps limit redeposition, scale, sludge and other deposits in suitable aqueous systems. Typical uses: Mineral sequestration, Beverage and food processing, Water softening and scale control.
