What Is Sodium trimetaphosphate?
Sodium Metaphosphate, Sodium Trimetaphosphate and Sodium Hexametaphosphate are all sodium polyphosphates made of repeating units of NaPO3. 
Sodium Metaphosphate generally refers to a long chain of NaPO3 units that is not soluble in water, which is why Sodium trimetaphosphate is sometimes called insoluble metaphosphate. 
Sodium Trimetaphosphate has three NaPO3 units, and Sodium Hexametaphosphate has six NaPO3 units. 
Both the Trimetaphosphate and the Hexametaphosphate are soluble in water. 
In cosmetics and personal care products, Sodium Metaphosphate, Sodium Trimetaphosphate and Sodium Hexametaphosphate are used in the formulation of makeup foundations, mascara, bath products, and moisturizing and skin care products.

Why is Sodium trimetaphosphate used in cosmetics and personal care products?
Sodium Metaphosphate, Trimetaphosphate and Hexametaphosphate inactivate metallic ions so as to prevent the deterioration of cosmetics and personal care products. 
Sodium Metaphosphate is also used to polish the teeth, reduce oral odor, or otherwise cleanse or deodorize the teeth and mouth. 
Sodium Trimetaphosphate minimizes the change in the pH of a solution when an acid or a base is added to the solution and Sodium Hexametaphosphate prevents the corrosion (rust) of metallic materials used in packaging cosmetics and personal care products.

Scientific Facts about Sodium trimetaphosphate: 
Sodium Trimetaphosphate, and Hexametaphosphate are all inorganic salts that are often referred to as glassy sodium polyphosphates. 
Sodium Metaphosphate, in the form of long chains, is referred to as insoluble metaphosphate.

Generic Name: STMP
Applications of Sodium trimetaphosphate include food processing, starch modification, pharmaceuticals, and potable water treatment.

Sodium trimetaphosphate Description: 
Sodium Trimetaphosphate (STMP)  is a Sodium Phosphate salt (NaPO3)3, supplier and exporter. 
Sodium Trimetaphosphate, Anhydrous (STMP) Powder is a clean, white powder. 
Sodium Trimetaphosphate Applications include food processing, starch modification, pharmaceuticals, and potable water treatment.

Product Application: 
Sodium Trimetaphosphate (STMP)  is a Sodium Phosphate salt (NaPO3)3, that when added to gypsum can help to optimize the setting time while enhancing the structural integrity of the wallboard.  
STMP is an important additive in the production of high throughput and high quality wallboard for use by businesses and individuals in the construction and home remodeling industry.

Product Procedure: 
sodium trimetaphosphate (“STMP”) can be utilized in the wallboard manufacturing process to increase the quality of wallboard. 
But note STMP is ineffective in high pH level environments (i.e., greater than 10). 
In all other environments, STMP can be used to increase the core quality of wallboard and allow manufacturers to reduce the amount of natural polymer (i.e., starch) used to produce wallboard of suitable quality. 

STMP is a combination of earth metals and is known by the chemical equation (NaPO3)3. 
In Sodium trimetaphosphates solid form Sodium trimetaphosphate is a salt, but when dissolved in an aqueous solution, Sodium trimetaphosphate is present as a trimetaphosphate ion.

Sodium trimetaphosphate Technical Specification: 
Sodium trimetaphosphate is believed that the addition of STMP to the slurry promotes long crystal growth. 
Such crystals add the most strength to the core of the wallboard and also serve to form stronger bonds between the core and paper. 
While in theory, STMP can be used by manufacturers to decrease costs by increasing the core quality of wallboard, Sodium trimetaphosphate has been discovered in practice that the current methods of adding STMP leads to further problems and delays.

Starch, food, modified: distarch phosphate (from sodium trimetaphosphate) belongs to the class of organic compounds known as oligosaccharide phosphates. 
These are carbohydrates containing between 3 and 9 sugar units, one of which bear one or more phosphate groups. 
Starch, food, modified: distarch phosphate (from sodium trimetaphosphate) is an extremely weak basic (essentially neutral) compound (based on its pKa).

Sodium trimetaphosphate is used as a crosslinking agent in the cross-linked amylase-resistant starch. 
Sodium trimetaphosphate acts as an intermediate in food industries. 
Further, Sodium trimetaphosphate serves as a corrosion inhibitors, anti-scaling agents, fillers, finishing agents, plating agents and surface treating agents.
Although drawn with a particular resonance structure, the trianion has D3d symmetry.
Hydrolysis of the ring leads to the acyclic sodium triphosphate:
Na3P3O9 + H2O → H2Na3P3O10
The main reactions of the triphosphate anion is ring-opening by nucleophiles, including amines.

The main component of sodium trimetaphosphate is a cyclic polymerized phosphate for food.
Sodium trimetaphosphate is widely used in the synthesis of bridged-type phosphate starch and phosphorylated soybean protein, and is one of the safest food-based polymeric phosphates. 
"Sodium trimetaphosphate" is a legal food additive announced by the Ministry of Health and Welfare to replace borax, and sodium trimetaphosphate has three functions similar to borax: 

1.The pH value of the boiled liquid reduces the gelatinization speed.
2.The esterification function of sugar reduces the phenomenon of gelatinization and bonding.
3.Protein bridging composite reaction, improve tissue viscoelasticity and make the product dry.

Since sodium trimetaphosphate can not only esterify starch by bridging to inhibit surface adhesion, Sodium trimetaphosphate can also bind to serine and lysine in rice protein to form phosphorylated protein due to its reactivity. 
Protects proteins from lye damage and loses nutritional value.
Therefore, Sodium trimetaphosphate is recommended that the manufacturer or the public add 0.2% sodium trimetaphosphate to the cooking liquid as needed to replace the borax which will endanger human health.

The effect of sodium trimetaphosphate (STMP) as an antiproteolytic and remineralizing agent on demineralized dentin was evaluated in vitro. 
The inhibitory potential of STMP at 0.5, 1.5, 3.5, and 5% against recombinant matrix metalloproteinases (MMPs) MMPs-2 and -9 was assessed by zymography. 
To investigate Sodium trimetaphosphates remineralization potential, 40 bovine root specimens were obtained and subjected to a demoralization protocol to produce caries-like dentin lesions.
After that, dentin surfaces were divided into 3 areas: (1) mineralized (no treatment); (2) demineralized; and (3) demineralized/treated with STMP and submitted to a pH-cycling associated or not with STMP (1.5, 3.5, or 5% STMP, 10 min of treatment). 
After that, superficial hardness (SH) and cross-sectional hardness (CSH) were determined. 
Polarized light microscopy (PLM) was used to qualitatively evaluate mineralization within the caries-like lesions. 

The zymographic analysis showed that STMP solution is a potent inhibitor of the gelatinolytic activity of MMPs-2 and -9 depending on the dose, since the lowest concentration (0.5%) partially inhibited the enzyme activity, while the higher concentrations completely inhibited enzyme activity. 
Regarding remineralization effect, only 1.5% STMP solution enhanced both the SH and CSH. 
PLM showed that the area treated with 1.5% STMP presented similar birefringence as mineralized sound dentin. 
In conclusion, 1.5% STMP solution is effective as an antiproteolytic agent against MMPs and promotes dentin remineralization.
