TRISODIUM PHOSPHATE


EC / List no.: 231-509-8
CAS no.: 7601-54-9
Mol. formula: H3O4P.3Na

Trisodium phosphate (TSP) is the inorganic compound with the chemical formula Na3PO4. 
Trisodium phosphate is a white, granular or crystalline solid, highly soluble in water, producing an alkaline solution. 
Trisodium phosphate is used as a cleaning agent, builder, lubricant, food additive, stain remover, and degreaser.

The item of commerce is often partially hydrated and may range from anhydrous Na3PO4 to the dodecahydrate Na3PO4 • 12H2O. 
Most often found in white powder form, it can also be called trisodium orthophosphate or simply sodium phosphate.


Production
Trisodium phosphate is produced by neutralization of phosphoric acid using sodium carbonate, which produces disodium hydrogen phosphate. 
Trisodium phosphate is reacted with sodium hydroxide to form trisodium phosphate and water.

Na2CO3 + H3PO4 → Na2HPO4 + CO2 + H2O
Na2HPO4 + NaOH → Na3PO4 + H2O

Uses
Cleaning
Trisodium phosphate was at one time extensively used in formulations for a variety of consumer-grade soaps and detergents, and the most common use for trisodium phosphate has been in cleaning agents. 
The pH of a 1% solution is 12 (i.e., very basic), and the solution is sufficiently alkaline to saponify grease and oils. 
In combination with surfactants, Trisodium phosphate is an excellent agent for cleaning everything from laundry to concrete driveways. 
This versatility and low manufacturing price made Trisodium phosphate the basis for a plethora of cleaning products sold in the mid-20th century.

Trisodium phosphate is still sold and used as a cleaning agent, but since the late 1960s, its use has diminished in the United States and many other parts of the world because, like many phosphate-based cleaners, it is known to cause extensive eutrophication of lakes and rivers once it enters a water system.

Trisodium phosphate is commonly used after cleaning a surface with mineral spirits to remove hydrocarbon residues and may be used with household chlorine bleach in the same solution without hazardous reactions.
This mixture is particularly effective for removing mildew, but is less effective at removing mold.

Although it is still the active ingredient in some toilet bowl-cleaning tablets, Trisodium phosphate is generally not recommended for cleaning bathrooms because it can stain metal fixtures and can damage grout.

Chlorination
With the formula Na3PO4.1/4NaOCl.11H2O the material called chlorinated trisodium phosphate is used as a disinfectant and bleach, like sodium hypochlorite. 
Trisodium phosphate is prepared using NaOCl in place of some of the base to neutralize phosphoric acid.

Flux
In the U.S., trisodium phosphate is an approved flux for use in hard soldering joints in medical-grade copper plumbing. 
The flux is applied as a concentrated water solution and dissolves copper oxides at the temperature used in copper brazing. 
Residues are water-soluble and can be rinsed out before plumbing is put into service.

Trisodium phosphate is used as an ingredient in fluxes designed to deoxygenate nonferrous metals for casting. 
Trisodium phosphate can be used in ceramic production to lower the flow point of glazes.

Painting enhancement
Trisodium phosphate is still in common use for the cleaning, degreasing, and deglossing of walls prior to painting. 
Trisodium phosphate breaks the gloss of oil-based paints and opens the pores of latex-based paint, providing a surface better suited for the adhesion of the subsequent layer.

Food additive
Sodium phosphates including monosodium phosphate, disodium phosphate, and trisodium phosphate are approved as food additives in the EU. 
They are commonly used as acidity regulators and have the collective E number E339.
The United States Food and Drug Administration lists sodium phosphates as generally recognized as safe.

Exercise performance enhancement
Trisodium phosphate has gained a following as a nutritional supplement that can improve certain parameters of exercise performance.
The basis of this belief is the fact that phosphate is required for the energy-producing Krebs cycle central to aerobic metabolism. 
Phosphates are available from a number of other sources that are much milder than TSP. 
While Trisodium phosphate is not toxic per se, it is severely irritating to gastric mucosa unless used as part of a buffered solution.

Regulation
In the Western world, phosphate usage has declined owing to ecological problems with the damage to lakes and rivers through eutrophication.

Substitutes
See also: Cleaning products and the environment
By the end of the 20th century, many products that formerly contained Trisodium phosphate were manufactured with Trisodium phosphate substitutes, which consist mainly of sodium carbonate along with various admixtures of nonionic surfactants and a limited percentage of sodium phosphates.

Products sold as Trisodium phosphate substitutes, containing soda ash and zeolites, are promoted as direct substitutes. 
However, sodium carbonate is not as strongly basic as trisodium phosphate, making it less effective in demanding applications.
Zeolites, which are clay based, are added to laundry detergents as water softening agents and are essentially non-polluting; however, zeolites do not dissolve and can deposit a fine, powdery residue in the wash tub.
Cleaning products labeled as Trisodium phosphate may contain other ingredients, with perhaps less than 50% trisodium phosphate.


What Is Trisodium Phosphate (TSP)?
Trisodium phosphate, commonly called TSP, is a packaged, blended cleaning product consisting of 75 to 80 percent trisodium phosphate and 20 to 25 percent sodium carbonate. 
Trisodium phosphate usually comes in the form of an odorless dry powder that must be thoroughly mixed into hot water to form a mostly clear solution, though slightly cloudy. 
Applied with sponges or scrub brushes, Trisodium phosphate is an effective, heavy-duty cleaner for problem areas around the house that may be sooty, greasy, or dirty. 
Though bans on phosphates are in effect in many communities, TSP, where legal, is often favored by contractors and painters to ensure that the surface will be clean, dust-free, and able to take the paint. 
Phosphate-free substitutes to Trisodium phosphate are available.

How to Clean With Trisodium Phosphate (TSP)
Prepare
Wear eye protection, long sleeves, and waterproof gloves. Use plastic sheeting to protect areas of the home that are not being cleaned with the TSP.

Mix the Solution
Mix 1/2 cup of Trisodium phosphate per 2 gallons of water for heavy-duty cleaning or 1/4 cup of Trisodium phosphate per 2 gallons of water for household cleaning. 
Make sure that the water is hot, as this allows the Trisodium phosphate to become soluble. 
Thus, wearing gloves not only helps to protect the skin but it allows you to handle hotter water than you could manage with bare hands.

Soak and Squeeze
With gloves on, soak the sponge in the water. 
Hold the sponge over the bucket and thoroughly squeeze it dry. 
A damp sponge is better than a wet sponge, since the wet sponge may leave tracks from drops of water.

Clean the Surface
Clean the surface from the bottom upward. 
Move the sponge in broad strokes to remove the worst of the debris. 
Again soak the sponge in the Trisodium phosphate solution and squeeze out, the more frequent, the better.

Clean Again
For difficult areas, a second cleaning with Trisodium phosphate is required. 
Rinse the cleaned area with warm water. 
Because Trisodium phosphate begins as a dry, white powder, it often can conclude as a dry, white powder on the surface after the water has dried. 
To combat this, make sure that you rinse the surfaces with a new sponge and a bucket that has been thoroughly rinsed out or even a new bucket.


What to Clean With TSP
Walls, ceiling, trim, and other woodwork before painting
Mold and mildew from decks
House siding
Soot on chimney mantels
Greasy stains and unidentifiable stains
Lead paint dust
Beams or joists in crawlspace
Mold in the home, before mold remediation

What Not to Clean With TSP
Though Trisodium phosphate can be used for a wide variety of surfaces, it cannot be used for all surfaces. 
Trisodium phosphate can darken or stain some materials, and it can etch glass and mirrors.
Keep Trisodium phosphate away from aluminum, as well as other metals, when the Trisodium phosphate solution is at its hottest. 
Paints that have a glossy sheen may lose their sheen if they come into contact with TSP. 
Hardwoods like oak and mahogany may darken if they are cleaned with TSP. 
If you have any concerns about whether or not to use Trisodium phosphate on a particular surface, test a small amount in an inconspicuous area first, or use a substitute cleanser.

Together with other phosphates, it modifies cereal color, aids the cereal's flow through the extruder and provides phosphorus fortification. 
Trisodium phosphate is also commonly present in cheese sauces as an emulsifier. 
Trisodium phosphate is a strong chemical and can cause severe eye damage and can burn unprotected skin. 
Poisoning occurs if you swallow, breathe in, or spill large amounts of Trisodium phosphate on your skin.

Chemical Properties    
Trisodium phosphate (anhydrous) is a white, granular or crystalline solid, highly soluble in water and produces a strong alkaline solution. 
On exposure to heat, trisodium phosphate decomposes and produces toxic and corrosive fumes including phosphorous oxides.
The major use for trisodium phosphate is as a cleaning agent, food additive, stain remover, and degreaser. 
Trisodium phosphate of commercial grade is often partially hydrated and ranges from anhydrous trisodium phosphate, Na3PO4, to the dodecahydrate, Na3PO4 · 12H2O. 
Most often found in white powder form, it is also called trisodium orthophosphate or just plain sodium phosphate. 
Trisodium phosphate reacts violently with water and acids to liberate heat. 
Trisodium phosphate is corrosive and in the presence of water attacks many metals.
Trisodium phosphate is an approved flux for use in hard soldering joints in medical grade copper plumbing. 
The flux is applied as a concentrated water solution and dissolves copper oxides at the temperature used in copper brazing.
Residues are fully water soluble and can be rinsed out of plumbing before it is put in service. Also, trisodium phosphate is still in vast use for the cleaning, degreasing, and deglossing of walls prior to painting. 
In fact, application of trisodium phosphate breaks the gloss of oil-based paints and opens the pores of latex-based paint providing a surface better suited for the adhesion of the subsequent layer of paint.


Physical properties    
The dodecahydrate is a white or colorless hexagonal crystal; density 1.62 g/cm3; melts around 75°C on rapid heating; partially loses water of crystallization at 100°C; retains the last water molecule even at moderate ignition; soluble in water, about 28 g/100 mL at 20°C; the solution is strongly alkaline; the pH of a 0.1M solution 11.5; insoluble in alcohol.

Uses    
Trisodium phosphate (TSP) is a cleaning agent, lubricant, food additive, stain remover and degreaser.

Substitutes are not as effective, but the raw chemical can be bought in bulk to add to other detergents. 
Trisodium phosphate works by disrupting the bacterial cell membrane and causing the contents to leak out, though the exact mechanism is not fully elucidated (Oyarzabal, 2005). 
Trisodium phosphate solutions are approved for treatment of beef carcasses in the US Code of Federal Regulations.
By the end of the 20th century, many products that formerly contained Trisodium phosphate were manufactured with Trisodium phosphate substitutes, which consist mainly of sodium carbonate along with various admixtures of nonionic surfactants and a limited percentage of sodium phosphates. 
Trisodium phosphate is commonly used after cleaning with mineral spirits in order to remove hydrocarbon residues. 
Trisodium phosphate may be used with household chlorine bleach in the same solution without hazardous reactions. 
This mixture is particularly good for removing mildew, but is ineffective at permanently removing mold.

sodium phosphate helps maintain product pH.

Trisodium Phosphate is an emulsifier and buffer that is strongly alkaline, with a ph of 12. 
Trisodium Phosphate is moderately soluble in water, with a solubility of 14 g/100 ml at 25°c. 
Trisodium Phosphate functions as an emulsifier in processed cheese to improve texture. 
Trisodium Phosphate maintains viscosity and pre- vents phase separation in evaporated milk and is also found in cereals. 
Trisodium Phosphate is also termed trisodium orthophosphate, sodium phosphate tribasic, and trisodium monophosphate.

Preparation    
Trisodium phosphate may be prepared in two steps, first by adding a little excess of sodium carbonate to phosphoric acid and then boiling the solution to expel carbon dioxide. 
Sodium hydroxide is then added to the solution:
Na2CO3+ H3PO4→Na2HPO4+ CO2+ H2O
Na2HPO4+ NaOH →Na3PO4+ H2O
Alternatively, trisodium phosphate may be prepared by complete neutralization of phosphoric acid with sodium hydroxide, followed by evaporation and crystallization:
H3PO4+ 3NaOH →Na3PO4+ 3H2O

Industrial uses    
Different salts of phosphoric and polyphosphoric acids are used in flotation.
From this fairly large family of reagents, sodium phosphate is the preferred species.
Trisodium phosphate is a white, crystalline substance highly soluble in water. 
Neutralizing phosphoric acid with soda ash produces trisodium phosphate.
Mono- and disodium phosphates are rarely used.


Trisodium phosphate is an inorganic compound used as a laxative, dietary supplement and for electrolyte-replacement purposes. 
Phosphate, a predominant intracellular anion, plays an important role in energy storage, osteoblastic and osteoclastic activities, regulating serum calcium concentrations, and numerous cellular phosphate-transfer reactions. 
Trisodium phosphate increases fluidity of the intestinal contents by retention of water by osmotic forces, thereby indirectly inducing intestinal smooth muscle constriction. 
Trisodium phosphate is also used in the renal excretion of hydrogen ions while promoting the reabsorption of sodium ions.

Trisodium phosphate is mainly produced as the dodecahydrate by complete neutralization of phosphoric acid with caustic soda or soda ash and subsequent crystallization. 
Since neutralization with soda ash does not proceed beyond the stage of the disodium salt, caustic soda must be added to complete the reaction. 
Frequently, mother liquors of mono- or disodium phosphate production or crystalline disodium phosphates are used as starting materials. 
In another process, trisodium phosphate is obtained by digestion of the phosphate-rich neutralization sludges, which accumulate in the purification of wet phosphoric acid by precipitation, with caustic soda and with addition of water glass

What Is Trisodium Phosphate & Its Applications?
Trisodium phosphate uses traditionally revolved around industrial and residential cleaning. 
As an ingredient in detergents, degreasers, and mildew removers, this powerful chemical features alkalinizing properties that made it popular in laundry detergents and dishwashing liquids since alkaline cuts through grease and oil. 
Trisodium phosphate was also used as a paint prep agent on interior and exterior walls and mixed with bleach to create a strong mold cleaner. 
However, it is not recommended for wood cleaning because of staining properties, nor is it used on metal or glass due to damage and filmy residue, respectively.

Trisodium phosphate was deemed harmful by the Environmental Protection Agency in 2011 and is listed as a “hazardous substance” under the agency’s Clean Water Act. 
The Center For Disease Control also discourages trisodium phosphate cleaner uses and lists shock, burning sensations, abdominal pain, and collapse as reactions to ingestion. 

Why Is Trisodium Phosphate In Food?
In addition to its many cleaning applications, trisodium phosphate is surprisingly utilized as a food additive. 
Trisodium phosphate is called E339 when used for food purposes. 
Main utilizations include its functions as a thickening agent, acidity regulator, emulsifier, and nutritional enlargement product. 
Most common foods containing the additive include meat, cheese, and baked goods. 
The chemical holds moisture in meat, whether stored or cooked, and helps cheese maintain its shape and melting abilities. 
Trisodium phosphate is used as a leavening agent in bread, cake, muffins, and similar products.

Trisodium phosphate in cereal is yet another common food application. 
The chemical makes minor changes to improve dry, extruded cereal color while also promoting the product’s flow through extruder equipment. 
Further cereal uses include phosphorus fortification.


Additional popular foods containing trisodium phosphate include lunch meat, ham, and other processed meats, rice syrup, canned soups, pizza dough, cake mixes, cheese sauces, and baked goods.

Almost any food requiring processing and freezing features this additive. 
Despite warnings from the EPA and CDC, the chemical is approved by the Food and Drug Administration (FDA) for food industry use. 
Trisodium phosphate’s reach even extends to the nutritional supplements many professional athletes use to enhance or support their physical abilities.

Uses for Trisodium phosphate 
Trisodium phosphate is used for washing surfaces prior to painting, especially exterior surfaces. 
Liquid bleach is often added to Trisodium phosphate if there is mildew on the surfaces. 
The Trisodium phosphate and bleach act in concert to both kill the mildew and remove its characteristic stains. 
Trisodium phosphate may be used on inside surfaces also, but try to mask all surfaces except the one you want to clean. 
Trisodium phosphate can damage many metal and painted surfaces, and can stain woods. 
Trisodium phosphate is not recommended for use on glass, either, since it will leave a filmy residue.

Trisodium phosphate can also be used as a masonry cleaner. 
However, if efflorescence or mortar staining are severe, you may need to resort to a more powerful but dangerous product, muriatic acid.

Trisodium phosphate and TSP-bleach solutions may be applied with a sponge or brush, or can be sprayed on. 
Generally, you will have to apply some elbow-grease if the mildew or other staining is severe.
If you are washing the exterior of a house, it may be worthwhile for you to look into the rental of commercial powerwashing equipment. 
You may be able to do all necessary cleaning from the ground level, sparing you the risk of extra ladderwork.

UsingTrisodium Phosphate To Clean Before Painting

Even if it’s not necessary to sand or strip a surface, all dirt and grime must be removed. 
Trisodium Phosphate can remove dirt, grease, soap scum and many more surface contaminates and is probably the most powerful cleaner to use on walls and trim.
Typical surfaces include painted walls, ceilings, wood trim and windows. 
Trisodium phosphate, also known as TSP, will strip away many years worth of grime leaving a clean and etched surface to maximize the paints adhesion.

Trisodium phosphate Mixing Instructions
Mix 1/4 cup per gallon of very warm water, for a super heavy-duty solution use 1/2 cup. 
Apply with a sponge and use a scrub pad for heavy deposits. 
Squeeze excess solution from the sponge and wash from the bottom up.
Allow the cleaning solution to sit on the surface for 1-2 minutes then rinse with warm water.
Repeated rinsing might be necessary to remove all the contamination and cleaner.
Pay attention to the mixing instructions on the box.
Not all products are the same. Strengths can vary between the different manufactures.
If repeated rinsing isn’t for you, try no-rinse Trisodium phosphate instead.
This formula isn’t as strong as standard trisodium phosphate, but will do a good job at removing house hold grease and grime. 
The best part is no rinsing is required when used according to directions.


Trisodium phosphate has a variety of applications but is primarily used as a cleaning agent, food additive, stain remover and degreaser.

Trisodium Phosphate as a Food Additive
"Trisodium phosphate is used to prolong shelf-life, and in some cases, to improve the texture of food or enhance the flavor. 

Trisodium phosphate in Cleaners and Other Household Products
As mentioned, trisodium phosphate has a number of uses. 
Until recently, it could be commonly found in household products from dishwasher detergents to garden fertilizers.

Here's why that's bad: Phosphorus runoff is one of the leading causes of water pollution, according to the New York State Department of Environmental Conservation. 
Because of this, 17 states, including New York, banned phosphorous ingredients in dishwasher detergents and fertilizers back in 2010.

If you're concerned about phosphate pollution, read the list of ingredients in your household products and avoid products with "phosphate" in the ingredients list.

Medical Uses

Though trisodium phosphate can have a number of negative effects on your health and the environment, it can be used beneficially in certain medications. 
Sodium phosphate can be used as a laxative or electrolyte replenisher, according to the NCBI.

Trisodium phosphate is a strong chemical. 
Poisoning occurs if you swallow, breathe in, or spill large amounts of this substance on your skin.

Trisodium phosphate (TSP) or sodium phosphate tribasic, a common food grade ingredient used in cereal and other processed foods. 
The European food additive number for it is E339(iii). 
Trisodium phosphate can be used as an acidity regulator to decrease acidity in cereal, a moisture retainer to improve the tenderness (or juiciness) in meat and seafoods, and a supplement to enhance phosphorus nutrient in food. 

What is trisodium phosphate?
Trisodium phosphate is an inorganic compound derived from naturally occurring minerals and existing mainly in two types: anhydrous with the chemical formula Na2HPO4 and dodecahydrate with chemical formula Na3PO4.12H2O.

How is it made? 
Similar with monosodium phosphate and disodium phosphate, it is also commercially produced by the reaction of phosphoric acid with sodium carbonate or sodium hydroxide (commonly used for its higher PH than sodium carbonate), but with more of these alkalines until none of the protons (H+) from phosphoric acid left.

The following is the synthesis equation:

3Na2CO3+2H3PO4→2Na3PO4+3H2O+3CO2↑
3NaOH+H3PO4→Na3PO4+3H2O
A specific hydrate can be obtained by heat dodecahydrate to 55℃ – 65℃ to get decahydrate, heptahydrate (65℃ – 105℃), hemihydrate (100-212℃) and anhydrous (above 212℃).

Properties
Trisodium phosphate is a strong base and a weak acid salt, which has a high solubility in water and produces a strong alkaline solution. 

Appearance

What are the uses of TSP?
In food, like other phosphates, food grade trisodium phosphate is used to keep moisture and maintain the flavor in seafoods, meat and poultry products and therefore increase the shelf life. 
Trisodium phosphate can hold moisture of food because its own basicity can increase the pH and ionic strength of food.

Trisodium phosphate can also function as a sequestrant to chelate metal ions in food. 
Its food grade is more purified, used with less amount than the technical grade which is mainly used as a cleaner and detergent. 
As a result, it is safer. 

In cereal products, it is used to reduce acidity. 
Trisodium phosphate also acts as an emulsifier in pasteurized process cheese and cheese food, and an acidity regulator in fruit jellies, preserves, and jams.  


Cosmetic
Per the “European Commission database for information on cosmetic substances and ingredients”, TSP functions as a buffering, and chelating in cosmetic and personal care products.

A mixture of food grade trisodium phosphate and baking soda can be used for homemade toothpaste/mouthwash as a mouth rinse after brushing teeth. Baking soda is a weak alkaline to adjust the alkaline of TSP mild. 

Industrial
Technical grade trisodium phosphate is a very important phosphate in industrial uses, e.g. in chemical, textile, printing, dyeing, papermaking and power generation industries.

Trisodium phosphate has the advantages of convenient use and cheap price and commonly used as a

Water softener 
Detergent
Metal descaling agent
Boiler cleaning agent
Stain remover, mildew/mold remover
Degreaser 
Acid-base buffer
Alkaline typically has a capacity to clean greases and oils. 
Trisodium phosphate sequestrates the metal ions such as calcium, magnesium,  aluminum and iron in water to be insoluble phosphate precipitates, thereby removing them from the water.

Trisodium phosphate can work as a descaling agent and cleaning agent for metals because trisodium phosphate can enhance the wetting ability of water and has a certain penetration and emulsification effect, so it can effectively remove the dirt on the metal surface. 
In addition, TSP is often added to liquid household bleach for cleaning.

What Is It?
Sodium Phosphate, Disodium Phosphate and Trisodium Phosphate occur as a white crystalline solids. 
These ingredients are also called monobasic sodium phosphate, dibasic sodium phosphate and tribasic sodium phosphate. 
In cosmetics and personal care products, the Sodium Phosphate ingredients are used in the formulation of bath products, colognes, dentifrices, mouthwashes, hair conditioners, hair dyes and colors, permanent waves, shampoos, makeup and skin care products.
