SODIUM PHOSPHATES
Tetrasodium Pyrophosphate TSPP
An alkaline pyrophosphate considered for buffering, mineral interactions and emulsifying-salt systems.
INGREDIENT OVERVIEW
TSPP: product profile
Tetrasodium pyrophosphate is an alkaline diphosphate. Anhydrous and decahydrate forms require separate specifications; neither should be confused with sodium acid pyrophosphate.
Also known as: TSPP · Tetrasodium diphosphate · Sodium pyrophosphate · Sodium diphosphate tetrabasic
TSPP and SAPP are different materials even though both are pyrophosphates. In protein-food discussions, the alkaline contribution and interactions of TSPP should be evaluated within the complete salt and phosphate system.

Emulsifying-salt systems: observe mineral/protein interactions, separation and set.
GRADE & PROCESS
An alkaline pyrophosphate for phosphate-system comparisons
Choosing the material
Anhydrous and hydrated material cannot share a water-loss assumption. Also distinguish assay after a specified treatment from an as-received result when comparing specifications.
Planning a useful comparison
Prepare the candidate under the same dissolution, mixing and temperature conditions as the benchmark. Record pH, undissolved material and the finished food’s texture and separation or moisture behavior.
GRADE & SPECIFICATION
Key parameters to confirm.
Specify the exact form, assay basis and dissolution needs. Compare a proposed grade under the same water, salt, temperature and mixing conditions as the existing material.
These are procurement questions, not a supplied specification. Units below indicate reporting context, not acceptance limits. Compare the current grade, source, document revision and test method before agreeing values.

| Parameter | What to request | Units or test context | Why it matters |
|---|---|---|---|
| Form and assay | Hydrate, analyte and reporting basis | Named form; analytical method | Do not transfer limits between hydration forms. |
| Alkalinity and dissolution | pH preparation and dissolution test | Concentration, temperature and time | Assess incorporation before comparing food performance. |
| Purity | Current impurity limits and test methods | Source-specific units and methods | Review the complete specification, not assay alone. |
PURCHASING QUESTIONS
TSPP: what to ask next.
Can TSPP replace SAPP in a leavening system?
Do not substitute on the pyrophosphate name. TSPP and SAPP have different acid-base roles; the complete acid–bicarbonate system needs its own design and trials.
What should accompany my inquiry?
Include the exact material and form, food application, destination market and target specification. Request current records for the proposed grade and source, and identify any methods your quality team requires.
Packaging, handling & ordering
State the form and whether you prepare a brine, slurry or dry mix. Request packaging and label details specific to the offered source, rather than using an unrelated phosphate’s storage period.
Share your quantity and required delivery timing. Minimum order, sample terms, packing and the stated shelf life belong to the specific quotation and source records.
Identity reference points
These sources support technical identity checks. They do not establish a supplied grade, source approval or permission in every food or market.
DOCUMENT REQUEST
Request documents for TSPP.
Tell us the material form, intended use, destination market and document purpose. Request Hydration-specific specification, TDS, analytical methods and representative COA. Records depend on the proposed grade and source; any certificate applies only within its stated entity, site and product scope.
