Tetra Potassium Pyrophosphate (TKPP)
Tetra Potassium Pyrophosphate (TKPP) is a highly soluble, multifunctional phosphate salt used as a powerful dispersant, chelating agent, and buffering ingredient across cleaning, water treatment, food processing, and specialty chemical applications.
CAS # 7320-34-5
Known for its excellent dispersing, chelating, and buffering capabilities, TKPP enhances product stability, prevents scale formation, and optimizes cleaning performance in a wide range of formulations. Manufacturers rely on TKPP for its purity, reliability, and ability to elevate both process efficiency and end-product quality.
TKPP is known for its ability to soften water, prevent scale, stabilize metal ions, and enhance formulation performance, delivering high-purity results that improve cleaning efficiency, product stability, and overall process reliability.
General Properties
Chemical Name: Tetra Potassium Pyrophosphate
Molecular Formula: K₄P₂O₇
Appearance: White, free-flowing powder or granules
Applications
Industrial Cleaners & Detergents
TKPP improves cleaning power by softening water, dispersing soils, and preventing redeposition making it ideal for heavy-duty degreasers, metal cleaners, vehicle washes, and institutional detergents.
Water Treatment
Acts as an effective sequestrant to inhibit scale formation and stabilize metal ions in industrial water systems, boilers, and cooling towers.
Food Processing
Used as a buffering agent, protein modifier, and emulsifier in select food applications to improve texture, moisture retention, and product stability.
Metal Treatment & Surface Preparation
Enhances corrosion control, improves rinsing efficiency, and supports surface cleaning prior to coating, plating, or finishing.
Ceramics, Paints & Pigments
Functions as a dispersant to maintain uniformity and improve flow characteristics in ceramic slurries, latex paints, pigments, and specialty coatings.
Advantages
Excellent Chelation & Sequestration: Effectively binds calcium, magnesium, and heavy metals to enhance cleaning power and prevent scale formation.
Highly Soluble for Easy Integration: Dissolves quickly in aqueous systems, simplifying processing and improving formulation consistency.
Enhances Stability & Performance: Maintains dispersion, controls alkalinity, and prevents precipitation in complex chemical formulations.
Versatile Across Industries: Suitable for cleaning products, water treatment, food processing (where permitted), metal preparation, and advanced material applications.
Safety & Handling
TKPP is generally regarded as low hazard but should be handled according to standard industrial safety practices.
May cause mild irritation to eyes or skin upon direct contact.
Avoid inhaling dust; use appropriate respiratory protection if dust levels are high.
Noncombustible, but good housekeeping prevents dust accumulation.
