Calcium Phytate CAS 3615-82-5

What Calcium Phytate Is

Calcium phytate, or phytin, is the calcium magnesium salt of inositol hexaphosphoric acid, better known as phytic acid, recovered by precipitating the steep liquors of rice bran or corn. The product is a white to off-white, odorless and tasteless amorphous powder. It does not dissolve in water but dissolves in dilute acid, and it binds multivalent metal ions such as calcium and iron strongly. Because the calcium to magnesium ratio and water content follow the source and process, phytin is not a single fixed molecule and lots are specified by calcium, magnesium and phosphorus content together with inositol yield. UATChem supplies both industrial phytin for hydrolysis and food or cosmetic grade powder, with these values reported on the COA for each lot.

Inositol, Food and Other Uses

• Inositol production. The principal precursor hydrolyzed and refined to myo-inositol for nutritional supplements, pharmaceuticals, food and fermentation.
• Food. Calcium fortification, multivalent metal chelation, antioxidant synergy, color protection and removal of iron or metal ions from wine and beverages.
• Cosmetics. A chelating and antioxidant aid in personal care formulas that stabilizes products and supports skin conditioning.
• Industrial. Chelating and corrosion inhibiting material in metal surface treatment, rust prevention and electroplating, and a base for other phytate salts.

Typical Specifications

Phytin composition varies with source and hydration, so calcium, magnesium and phosphorus content, moisture and inositol yield are reported on the COA for each lot instead of a single assay value; the physical properties below identify the material.

Packaging, Documents and Ordering

• Packed in 25 kg fiber drums with liner and in 500 kg FIBC bulk bags; containers stay sealed, dry, cool and moisture protected during storage and transit.
• Food and cosmetic grade phytin is safe within normal use and essentially non-toxic, with standard dust protection in handling. Every lot carries a COA with calcium, magnesium and phosphorus content, inositol yield, moisture and particle size, together with TDS and SDS, and food compliance documents or statements and samples can be discussed at inquiry.
• For a quote, UATChem needs the grade (industrial hydrolysis, food or cosmetic), target inositol yield or calcium and phosphorus values, quantity, packing and destination port.

FAQ

Q: What is calcium phytate used for?

A: It is hydrolyzed to make inositol, and used as a food calcium fortifier, metal chelator and cosmetic antioxidant aid.

Q: Why does calcium phytate have no single purity value?

A: Plant derived phytin has variable Ca/Mg and hydration, so lots are graded on Ca, Mg and P content and inositol yield.

Q: Is calcium phytate soluble in water?

A: No, phytin is insoluble in water and dissolves in dilute acid, the form used in inositol hydrolysis and analytical work.
