Scientific Facts about Tricalcium Phosphate: 
Calcium Phosphate is often used as a dietary supplement in prepared breakfast cereals, enriched flour and noodle products.

The use of calcium (Ca) supplements by postmenopausal women is growing rapidly. 
A commercial preparation of tricalcium phosphate (TCP) is available in the USA. 
Depending on the relative absorption of Ca versus phosphate, a rise in serum phosphorus (P) could stimulate parathyroid hormone (iPTH) secretion. 
We therefore compared Ca absorption and the metabolic responses following TCP to that of Ca carbonate (CC) on separate occasions in each of 10 women, aged 22-40 years. 
The subjects were fasted overnight for 12 hours while good hydration was maintained. 
Following a 2-hour baseline-urine collection, 1200 mg calcium (as CC or TCP) was ingested and two 2-hour postload urine collections were made. 
Blood was drawn at 1, 2, and 4 hours after the Ca load. 
Serum (S) and urine (U) Ca, P, and creatinine, and U cyclic AMP (cAMP) were determined. iPTH levels following TCP were also measured. 
Ca absorption was determined by the postload rise in Uca above baseline. 
Uca excretion increased significantly and was accompanied by significant rises in Sca after both preparations. 
Following TCP, S and U phosphorus increased. Urinary cAMP did not change after either preparation, and iPTH levels fell after oral TCP. 
We conclude that Ca taken as TCP is absorbed adequately and, thus, despite a rise in the S phosphorus level does not stimulate parathyroid activity.

Properties of tricalcium phosphate and effects of many other ingredients upon the structure and solubility of the phosphate were investigated. 
By the reaction of calcium salts with phosphates in aqueous solution, tricalcium phosphate hydrate with a definite structure is not formed but hydroxy apatite with an excess of phosphoric acid is formed, which varies to β-tricalcium phosphate by heating between 700–800°C. 
Contrary to many other reports, it was found that β-tricalcium phosphate was fairly soluble in citric acid. 
The solubility is reduced remarkably by a small amount of admixtures, especially of magnesia. 
Magnesia stabilizes the β modification and prevents β→α inversion of the phosphate. 
The effect of alumina and ferric oxide is similar but not so intense as magnesia.

Although caries continues to be the most prevalent dental disease worldwide, significant reductions in dental caries have been reported over the past 30 years. 
The decline is attributed to nearly universal use of products containing fluoride, such as toothpastes and oral rinses, as well as professionally applied compounds containing higher concentrations of fluoride.
Fluoride is proven to prevent tooth decay. 
Tricalcium Phosphate does so by inhibiting demineralization, enhancing remineralization, and inhibiting bacterial activity in dental plaque. 
In recent years, we’ve advanced our understanding of the roles calcium and phosphate also play in remineralizing toothpastes and other dental products.
Clinical trials have shown that applying products with high concentrations of both calcium and fluoride may not result in greater protection against tooth decay.
That’s because the calcium and fluoride can combine during storage to form calcium fluoride—which renders the fluoride less effective in preventing tooth decay.
However, 3M ESPE has introduced a proprietary calcium phosphate ingredient, Tri-Calcium Phosphate (TCP), that can be protected from unwanted interactions with fluoride during storage. 
This protected calcium additive works with fluoride to initiate high-quality mineral growth—acting as a catalyst to enhance remineralization and build a high-quality, acid-resistant mineral.
In addition, this innovative technology in toothpaste can be tailored to provide short- or long-term mineral delivery in a variety of dental products.

Tricalcium Phosphates Clinical Applications
Fluoride Toothpaste
As the functionalized TCP ingredient is protected from unwanted interactions with fluoride within the toothpaste during storage, Tricalcium Phosphate remains stable and allows for more fluoride availability. 
During brushing, both fluoride and the TCP ingredient are delivered to the tooth and provide enhanced remineralization and added protection against demineralization. 
Several laboratory studies have proven superior performance when the TCP material is added to fluoride toothpastes at optimal concentration. 

Protects against lesion initiation and progression
The purpose of this study was to determine how well different toothpaste formulations protect against carious lesion formation and progression.
In this study, a well-established pH-cycling model was used to mimic enamel lesion initiation and progression. 
Sound tooth enamel samples were subjected to periods of demineralization with an acid solution, and remineralization with various toothpaste treatments and artificial saliva. 
Samples were analyzed using cross-sectional microhardness to ensure the entire lesion body was analyzed.

High levels of calcium can cause:
-constipation
-nausea
-vomiting
-stomach pain
-muscle pain
-weakness
-excessive urination

Three years of inadvertent excessive inhalation and ingestion of the dust from a dentifrice resulted in the systemic accumulation of tricalcium phosphate crystals and granulomatous lesions in a patient who died from carcinomatosis apparently unrelated to the crystallosis. 
Dyspnea and cough were the only symptoms. 
Crystals detected in the tissues by high magnification and polarized light and identified by x-ray-diffraction analysis matched those of the dentifrice, and of standard tricalcium phosphate. 
Continual heedless exposure to minute, insoluble, airborne crystals dispersed from widely used powdery abrasive substances may have caused other instances of systemic or pulmonic granulomas.

Application: Tricalcium phosphate is a calcium salt of phorphoric acid that has uses in fertilizers, as a food additive, water filtration, and in some medical applications. 
Tricalcium Phosphate serves as a source of phosphorous for some fertilizers. 
As a food additive, Tricalcium Phosphate is used as a raising agent or sometimes as a nutritional supplement. 
Medically, Tricalcium Phosphate has application in bone graphs, but also as an antacid.

Compatibility: Tricalcium phosphate is incompatible with strong oxidizing agents, strong acids, and alkalis. 
Please see SDS for full safety and compatibility information.

Why is calcium important?
Calcium is a nutrient that is essential for strong bones. 
Ninety-nine percent of your body's calcium is stored in your bones and teeth. 
The other one percent of your body's calcium is found in blood. Blood calcium is necessary to support your body's critical functions such as controlling your blood pressure and maintaining your heartbeat.
The calcium in your bones makes up your bone bank. 
Throughout your lifetime, the calcium from the foods you eat is "deposited" in and "withdrawn" from your bone bank, depending on your needs. 
When your calcium intake is too low to keep your blood calcium normal your body will "withdraw" the calcium it needs from your bones. 
Over time, if more calcium is taken out of your bones than is put in, the result may be thin, weak bones that may break more easily.

Consumers know calcium is important for bone and teeth health. 
Cal-Sistent micronized Tricalcium Phosphate (TCP) from ICL Performance Products helps manufacturers provide calcium fortification without altering the well-established tastes or mouth feel of consumers’ favorite foods and beverages. 
Produced through a unique manufacturing process, a minimum of 95 percent of Cal-Sistent’s TCP particles are less than 20 microns. 
The small particle size makes Cal-Sistent ideal for products with a well-established taste or mouth feel because Tricalcium Phosphate is non-detectable in the human mouth, exhibits excellent suspension properties and does not affect product flavor. 
Cal-Sistent delivers a calcium content of 38 percent and calcium to phosphorus ratios equivalent to those in human bones. 
The calcium and phosphorus work synergistically to help prevent osteoporosis.
