What Is IP6?
IP6 (Inositol Hexaphosphate) is a naturally occurring compound also known as Phytin, calcium-magnesium phytate, or calcium-magnesium inositol hexaphosphate. Its CAS registry number is 3615-82-5 and its EINECS reference is 222-798-1. In its commercial form from GEM, IP6 is supplied as a white or off-white powder that is odorless and tasteless.
Physically, IP6 is poorly soluble in water and insoluble in common organic solvents such as anhydrous ethanol, ethyl ether, benzene, and chloroform. It dissolves readily in inorganic acids, a property that matters for certain industrial and processing routes. These solubility characteristics help formulators predict how the ingredient will behave during blending, coating, or acid-based production steps.
GEM IP6 is corn-derived, supplying a mineral-rich phytate compound used primarily to fortify foods and feeds with calcium, magnesium, and phosphorus. It is distinct from the free cyclitol Myo-Inositol, which GEM also supplies. Where Myo-Inositol is the unesterified inositol ring, IP6 is the fully phosphorylated hexaphosphate ester form, giving it a different chemistry, solubility, and application profile.
Because the ingredient arrives as a stable, free-flowing powder, it is straightforward to handle in dry-mix operations, tableting pre-blends, and extruded or pelleted feed systems. The neutral sensory profile means it can be added without rebalancing flavor systems, an advantage in sensitive formulations such as dairy, beverage, and companion-animal products.
Source & Chemistry
To understand IP6 as a functional ingredient, it helps to look at where it comes from and how it is structured. IP6 is the hexaphosphate ester of myo-inositol, a six-carbon carbocyclic sugar alcohol often described as a cyclitol. In its fully protonated, acid form it is called phytic acid (myo-inositol hexakisphosphate); when it binds mineral cations such as calcium and magnesium, it becomes a phytate salt — the mixed calcium-magnesium salt being the material commonly known as Phytin.
The free-acid parent, phytic acid, has the molecular formula C6H18O24P6 and a molecular weight of approximately 660.04 g/mol. All six hydroxyl groups of the myo-inositol ring are esterified with phosphate, giving the molecule six phosphate groups and twelve dissociable phosphate protons. At neutral and alkaline pH the molecule is strongly deprotonated and carries a high negative charge, which is the chemical basis for its strong affinity for positively charged mineral ions.
In nature, inositol hexaphosphate is the principal storage form of both phosphorus and inositol in plant seeds. It accumulates in the bran and germ of cereal grains and is abundant in legumes, nuts, and oilseeds. Corn (maize) is one of the richest and most commercially accessible sources, which is why GEM selects corn as the origin for its IP6 raw material. The calcium-magnesium phytate form occurs naturally in seeds as the mineral-bound storage complex.
This plant-seed origin is important for formulators building clean-label products. Because GEM IP6 is corn-derived and produced without genetically modified organisms, it aligns with non-GMO and plant-based positioning. The same phosphate-rich structure that stores minerals in the seed is what makes IP6 useful for delivering calcium, magnesium, and phosphorus in finished formulations. As a result, the ingredient bridges two roles at once: a natural plant-derived raw material and a concentrated multi-mineral delivery system.

Application Fields
IP6 serves several distinct industries. The table below summarizes the main application fields and how the ingredient is typically used in each.
| Application Field | Details |
|---|---|
| Food Fortification | Supplement for calcium, magnesium, and phosphorus in fortified foods; direct addition to food formulations or as a nutritional component |
| Animal Feed | Nutritional supplement to enhance feed mineral content and support livestock growth performance |
| Industrial Applications | Anti-corrosive coating for metal surfaces; raw material in ceramics and glass production |
| Agriculture | Soil fertilizer application to improve soil fertility and support crop growth |
| Dietary Supplements | Ingredient in mineral and inositol-related supplement lines, often paired with Myo-Inositol |
Formulators in food and feed often combine IP6 with complementary plant proteins such as Rice Protein or Pea Protein Powder when building complete, clean-label fortified systems. Pairing a mineral phytate with a plant protein lets a single product address both protein and mineral targets while keeping the ingredient list short and recognizable to consumers.
Production & Quality
GEM produces IP6 from corn through extraction and purification routes that preserve the natural calcium-magnesium phytate structure. The material is processed without ethylene oxide (Non-ETO) and without irradiation (Non-Irradiation), and it carries confirmed Non-GMO status. These processing choices matter to buyers building clean-label, food-grade, and supplement-grade products where residue limits and process transparency are audited.
Quality is governed by an integrated food-safety system. GEM holds ISO22000, FSSC22000, ISO9001, and GMP certifications, and the product is available with Kosher and Halal certification for qualified commercial orders. Finished lots are released only after testing against the full specification table above, using validated methods that include spectrophotometry, ICP, EDTA titration, atomic absorption spectrometry, gravimetric analysis, and microbiological plate-count procedures.
Supply reliability is supported by an annual production capacity of 30+ tons and consistent 20 kg/drum packaging. Under recommended storage conditions — a cool, dry place, away from direct sunlight, with containers kept sealed — the shelf life is 24 months. GEM provides a Specification Sheet, Certificate of Analysis (COA), and Material Safety Data Sheet (MSDS) on request to support B2B qualification, auditing, and regulatory submissions.
For formulators needing formulation support, GEM's technical team can advise on inclusion levels, compatibility with other ingredients, and documentation for specific regulatory markets. Because inclusion rates vary by target mineral content and food or feed matrix, early technical engagement helps avoid rework and speeds up product development.
Frequently Asked Questions
2. What is the difference between IP6 and phytic acid?
Phytic acid is the fully protonated free-acid form of inositol hexaphosphate (molecular formula C6H18O24P6). IP6 as supplied by GEM is the mixed calcium-magnesium phytate salt (Phytin). In short, phytic acid is the acid; the commercial IP6 ingredient is its mineral salt.
