The Essential Mineral Compound: Premium Trimagnesium Phosphate by SRBio
SRBio Trimagnesium Phosphate is a high-purity, inorganic magnesium salt offering a concentrated source of two essential minerals: magnesium and phosphorus. This white, crystalline powder is valued in nutritional and pharmaceutical formulations for its high magnesium content, neutral taste, and excellent stability. Ideal for applications requiring precise mineral fortification without altering the organoleptic profile of the final product.
Uncompromising Quality: SRBio’s Manufacturing Excellence
-
Precision Purity & Composition Control
-
High Purity Assay: Guaranteed assay of 98.0% – 101.5% on an anhydrous basis, ensuring accurate and reliable mineral content for your formulations.
-
Controlled Heavy Metals: ICP-MS validated limits: Arsenic (<1.0 ppm), Lead (<1.0 ppm), Cadmium (<0.5 ppm), Mercury (<0.1 ppm). Compliant with global food safety standards.
-
Loss on Drying: Strictly controlled moisture content (<2%) to ensure stability and prevent clumping.
-
-
Advanced Synthesis Technology
-
Controlled Precipitation Reaction: Our process involves a precisely controlled reaction between high-purity magnesium sources and pharmaceutical-grade phosphoric acid. This ensures a consistent stoichiometry and a pure, well-defined crystal structure.
-
Multi-Stage Washing & Purification: The precipitated product undergoes multiple washing cycles with deionized water to remove by-product salts and unreacted ions, achieving exceptional purity.
-
Optimized Drying & Milling: Low-temperature fluidized bed drying prevents degradation. Subsequent milling and sieving guarantee a uniform, free-flowing powder with customizable particle size distribution for various applications.
-
-
Stability & Shelf-Life Superiority
-
Long-Term Stability: As an inorganic salt, it exhibits inherent stability. Accelerated studies confirm it retains its chemical integrity and physical properties for over 36 months when stored properly.
-
Low Hygroscopicity: Unlike many other mineral salts, trimagnesium phosphate has very low moisture absorption, ensuring excellent flowability and preventing caking during storage and high-speed manufacturing.
-
Recommended Storage: Store in a cool, dry, well-ventilated warehouse away from moisture and strong acids/alkalis. Keep sealed during transport.
-
Scientific & Functional Overview
-
Dual Essential Mineral Source
-
High Magnesium Content: Provides a concentrated source of elemental magnesium (approx. 34% by weight), crucial for muscle and nerve function, energy metabolism, and bone health.
-
Bioavailable Phosphorus: Supplies phosphorus, a vital component of bones, teeth, ATP, and cell membranes, working synergistically with calcium and magnesium.
-
-
Food & Pharmaceutical Applications
-
Mineral Fortification: An ideal choice for enriching foods, beverages (especially powdered mixes), and nutritional supplements with both magnesium and phosphorus without impacting taste.
-
Anticaking Agent (Food Additive): Its excellent free-flowing properties make it effective as an anticaking agent in powdered food products, seasonings, and table salts (recognized as generally safe).
-
-
Specialized Industrial Uses
-
Dental Materials: Utilized as a component in dental cements and polishing agents due to its mild abrasive and setting properties.
-
Technical Precipitant: Serves as a precipitant or raw material in various chemical and industrial processes.

Formulation-Ready Advantages
| Property | SRBio Trimagnesium Phosphate | Competitor Average |
|---|---|---|
| Assay (Mg₃(PO₄)₂ basis) | 98.0% – 101.5% (tightly controlled) | Often variable, may fall below 97% |
| Appearance | Pure white, free-flowing powder | Off-white, may contain specks or clumps |
| Solubility | Insoluble in water; soluble in dilute acids | – |
| Bulk Density | 0.50 – 0.80 g/cm³ (customizable) | Highly variable, often too light or too dense |
| Particle Size | 100% through 100 mesh; options for finer grades | Inconsistent, causing blending issues |
| Heavy Metals | Consistently below regulatory limits (FCC/USP) | May approach upper limits |
Application-Specific Benefits:
-
Tablets & Capsules: Excellent compressibility and flow. Its high density compared to organic magnesium salts allows for smaller tablet sizes for the same elemental magnesium dose.
-
Powdered Blends: Acts as a flow agent itself, preventing segregation and ensuring homogeneous blends with other vitamins, minerals, and excipients.
-
Food Fortification: Neutral taste and odor ensure no flavor impact on the finished product. Ideal for meal replacements, protein powders, and infant formula.

-
Competitive Breakdown: SRBio vs. Market Alternatives
Key Deficiencies in Standard Trimagnesium Phosphate:
-
Inconsistent Assay: Fluctuating magnesium/phosphate ratios can lead to unpredictable dosing and formulation failures.
-
Poor Physical Properties: High variability in bulk density and particle size leads to poor flow, segregation in blends, and issues with tablet compression (e.g., capping, weight variation).
-
Higher Impurity Profile: Elevated levels of heavy metals or other trace impurities can limit its use in high-quality nutritional and pharmaceutical products.
-
Clumping/Caking: Inadequate drying or packaging leads to moisture pickup and clumping, rendering it unusable for manufacturing.
SRBio’s Manufacturing Edge:
-
Guaranteed Stoichiometry: Our controlled precipitation process ensures a consistent and reliable 3:2 molar ratio of magnesium to phosphate.
-
Superior Physical Properties: Optimized for formulators with consistent density, particle size, and guaranteed free-flowing characteristics.
-
High Purity Standard: Consistently exceeds pharmacopoeial purity requirements, making it suitable for the most sensitive applications.
