Frequently Asked Questions
What is tetrapotassium pyrophosphate used for?
Tetrapotassium Pyrophosphate (TKPP, CAS 7320-34-5, K4P2O7) is used as a sequestrant and builder in detergents and surfactant systems, for scale and hardness control in process water, as a clay thinner/deflocculant in drilling muds, and as a chelating and pH-buffering agent.
What is tetrapotassium pyrophosphate?
It is a soluble potassium polyphosphate with formula K4O7P2. It is supplied as a powder or solution and functions as a chelant, buffer, and detergent builder.
How is tetrapotassium pyrophosphate different from tetrasodium pyrophosphate?
Both are pyrophosphate (P2O7) salts, but TKPP uses potassium counter-ions while tetrasodium pyrophosphate uses sodium. TKPP is markedly more water-soluble, which is why it is favored in concentrated liquid cleaning and process formulations.
What HS code applies to tetrapotassium pyrophosphate?
It ships under HS 2835.39, covering other polyphosphates. Confirm the destination-country classification with your customs broker.
What packaging and documentation does RawSource supply?
RawSource supplies tetrapotassium pyrophosphate in bulk bags, supersacks, drums, or totes depending on the grade ordered, with CoA and SDS available on request. Request a bulk quote with your target grade and volume.
