What is Disodium Phosphate (DSP)? Chemistry, Uses & Safety of Na2HPO4

Disodium phosphate (often abbreviated as DSP in formulation; also called disodium hydrogen phosphate) is a neutral-to-mildly alkaline phosphate salt with the formula Na2HPO4. It is widely used because it delivers three “system-control” functions at once: reliable pH buffering (typically in the alkaline range), metal ion sequestration (binding Ca2+/Mg2+), and protein/dispersion stabilization. These properties make DSP […]

What is Sodium Pyrophosphate (SPP)? Chemistry, Uses & Safety of Na4P2O7

Sodium pyrophosphate (often abbreviated as SPP in industry) most commonly refers to tetrasodium pyrophosphate, a multifunctional phosphate salt with the formula Na4P2O7. It is valued for three core functions: chelating metal ions (binding Ca2+/Mg2+), buffering/adjusting pH in alkaline ranges, and improving dispersion & texture across complex mixtures. These capabilities explain why SPP appears in applications […]

What is Single Super Phosphate (SSP)? Composition, Manufacturing & Uses as a Phosphate Fertilizer

Single super phosphate (SSP) is a water-soluble phosphate fertilizer made by reacting finely ground phosphate rock with sulfuric acid. What keeps SSP globally relevant is its three-in-one nutrition: it supplies phosphorus (P) for roots and early growth, plus sulfur (S) and calcium (Ca)—often the “missing” nutrients in many soils. Although higher-analysis phosphate fertilizers exist, SSP […]

Sodium Tripolyphosphate (STPP): The Ultimate Ceramic Deflocculant

The definitive water-reducing agent for high-efficiency ceramic production. ✅ Reduce Water Content: Save 10-15% energy in spray drying towers. ✅ Improve Flowability: Achieve optimal viscosity without adding excess water. ✅ Flawless Glaze: Eliminate pinholes and “crawling” defects. Get Technical Data Sheet (TDS) Why STPP is Critical for Ceramic Slurry? (The Science) In ceramic manufacturing, “Mud […]

Sodium Acid Pyrophosphate (SAPP): The Baking Industry Standard

Sodium Acid Pyrophosphate (SAPP), chemically known as Disodium Pyrophosphate (Na₂H₂P₂O₇), is the gold standard leavening acid for the baking industry. It determines the volume, texture, and taste of everything from donuts to baking powders. Sodium Acid Pyrophosphate (SAPP) has become the baking industry’s standard slow-acting leavening acid due to its controlled CO₂ release profile and […]

Tetrasodium Pyrophosphate (TSPP): The Industrial & Food Grade Guide

Tetrasodium Pyrophosphate (TSPP), also known simply as Sodium Pyrophosphate, is a powerful alkaline phosphate used to emulsify proteins in meat, control tartar in toothpaste, and chelate magnesium in detergents. As a manufacturer, Goway Chemical helps buyers distinguish between the various pyrophosphates to ensure the right functionality for your formulation. TSPP increases the pH and ionic […]

Sodium Acid Pyrophosphate (SAPP): Types, Grades, Functions, and Applications in Food Processing

Sodium formate

Sodium Acid Pyrophosphate (SAPP) is one of the most widely used food-grade phosphates in bakery, fried foods, processed meats, and instant products. Known for its controlled reaction rates and functional versatility, SAPP plays a crucial role in leavening systems, color stabilization, texture improvement, and pH adjustment. This guide explains SAPP’s chemical behavior, type classifications, application […]

STPP vs SHMP vs TSPP: Differences, Functions, and Best Applications Explained

Phosphate additives play a central role in food processing, detergents, ceramics, and other industrial formulations. Among them, sodium tripolyphosphate (STPP), sodium hexametaphosphate (SHMP), and tetrasodium pyrophosphate (TSPP) are the most frequently used due to their unique chemical behaviors and broad functionality. Although these phosphates belong to the same family, their performance and application suitability vary […]

What is Tripotassium Phosphate (TKP)? Chemistry, Uses & Safety in Food and Industry

Tripotassium Phosphate: Uses, Safety, and Benefits Explained

From keeping your oat milk smooth to cutting through kitchen grease, tripotassium phosphate (TKP) leverages its strong alkalinity to solve problems across food and industrial sectors. This guide clarifies TKP’s chemistry, regulatory status, and precise roles — while clearly distinguishing it from cleaning-only phosphates such as trisodium phosphate (TSP). Part of Goway’s comprehensive Phosphates Encyclopedia. […]
