Frequently Asked Questions (FAQ)
What is Tetrapotassium Pyrophosphate (TKPP) used for?
TKPP is a versatile multifunctional phosphate used across food processing (as an emulsifier, texture modifier, and chelating agent), industrial applications (electroplating, detergents, water treatment), and agriculture (as a potassium and phosphorus source in liquid fertilizers).
What is the purity level of your TKPP product?
Our TKPP has a minimum purity of ≥ 98.0%, with water insoluble matter ≤ 0.1%, ensuring high-quality performance in both food-grade and industrial-grade applications.
What is the pH level of a TKPP solution?
A 1% aqueous solution of TKPP has a pH range of 10.0 – 11.0, confirming its strongly alkaline nature, which makes it effective as a buffering agent in alkaline formulation systems.
How does TKPP function as a chelating agent?
TKPP binds strongly to divalent and heavy metal ions such as Ca²⁺, Mg²⁺, and Fe²⁺, preventing them from interfering with product quality. This makes it highly effective in water treatment, food preservation, and industrial cleaning formulations.
What packaging options are available for TKPP?
TKPP is available in standard 25 kg bags. Customized packaging solutions are also supported, including OEM and ODM options to meet specific branding or logistical requirements.
Is TKPP suitable for use in liquid fertilizer formulations?
Yes. TKPP's high water solubility and strong chelating ability make it an excellent additive in liquid fertilizer systems. It improves nutrient stability, prevents precipitation of micronutrients, and provides readily available potassium and phosphorus for plant uptake.
