Stpp chemical uses


Sodium tripolyphosphate STPPalso known as pentasodium triphosphate, pentasodium tripolyphosphate or sodium triphosphate, is used in a wide range of applications in the manufacture of cleaning products and food preservatives as well as in water treatment facilities. STPP is a sodium salt of triphosphoric acid that has the appearance of white crystal powder.

It is odorless and is water soluble. In a highly controlled environment, it is made by combining monosodium phosphate and disodium phosphate. A Powerful Cleaning Agent Sodium tripolyphosphate Na5P3O10 is a strong cleaning ingredient that typically can rid dishes and fabrics of soil and spots. Its key function is that it allows surfactants to work at their full potential. Also, it prevents deposition of soil and acts as a pH buffer.

It softens detergent water and can be used as a water treatment, as well. Many household cleaning products, including surface and toilet cleaners, contain STPP due to its cleaning component. It can be used to preserve foods such as red meats, poultry, and seafood, helping them to retain their tenderness and moisture.

Pet food and animal feed have been known to be treated with STPP, serving the same general purpose as it does in human food. STPP also has been used in helping to preserve the quality of drinks such as milk and fruit juices. Other Uses As a builder, sodium tripolyphosphate mainly is used in detergents and soaps.

This includes dishwasher detergents as well as laundry detergents. It is used in most gel, liquid, tablet, and powder forms of each type of detergent. In the detergent, it helps strengthen the cleaning action. It is used in paint as a pigment dispersant.

Ceramics use it to help disperse clay, and paper mills use it as an oil-resistant agent when coating paper. It additionally has been used as a tanning agent in making leather, and the minerals in cement have been known to be treated with it. Sodium tripolyphosphate also has been used as an additive in toothpaste due to its cleaning action. Cautions It generally is advised that sodium tripolyphosphate be stored in a cool and well-ventilated area.

Direct sunlight and damp areas usually should be avoided. If STPP comes into contact with skin, the area should be thoroughly rinsed. If eye contact is made, it is important to immediately flush the eyes. Sweety is the freelance writer for e-commerce website in the chemistry.

The information is aggregated from the data coming from REACH substance registrations provided by industry.The term phosphate refers to any one of a wide variety of chemical compounds that contain phosphorus, a naturally occurring mineral, bonded together with oxygen. The term is used both in inorganic chemistry and organic chemistry. In inorganic chemistry, the phosphate ion combines one phosphorus atom with three or four oxygen atoms, forming the base for many different salts.

Phosphate molecules are usually found in combination with other elements, such as calcium, sodium, potassium, and aluminum. Naturally occurring inorganic phosphates are found in virtually every living thing, and synthetic phosphates are used in a wide variety of applications, including cleaning and baking products, as well as fertilizers. According to the Phosphate Forum of the Americasphosphates fall into three major groups: orthophosphatespyrophosphatesand polyphosphates, of which tripolyphosphates are one subgroup.

The categories refer to the number of phosphate units that are linked together in the molecule.


There are several types of phosphates, but these are the phosphates most often found in cleaning products:. Phosphates are used in automatic dish detergents and laundry detergents to help soften water and to remove soil, oil, and grease. They also help prevent spotting and film build-up in automatic dish detergents.

Due to their ability to cut through soap scum and mineral build-up, they are sometimes used in tile and porcelain cleaning products. In addition, phosphates may be used in specialty cleaners, such as concrete cleaners.

In addition to cleaning products, phosphates have a dizzying number of other uses. They may be found in water-based paints and coatings, metal polishes, flame retardants, processed foods, personal care products, pharmaceutical products, and more.

For example, STPP is used to preserve the moisture and flavor in shrimp and ham. Phosphates occur naturally in certain foods, but when added to processed foods they can have serious health effects if large amounts are consumed.

Phosphate food additives have been shown to stimulate lung cancer development. High phosphate content in processed foods can also affect renal and cardiovascular function. When phosphates are used in cleaning products, they can also cause health problems.

Housekeeping employees in New York medical establishments reported a reduction in symptoms, such as rashes, dizziness, and scratchy throats, once they started using phosphate-free cleaning products.

In the environment, large amounts of phosphates flowing into water supplies enhance algae growth and reduce the oxygen available for fish and plants in streams and lakes. When phosphates are used in food, personal care, and pharmaceutical preparations, they are monitored by the U. Phosphates have been banned for use in laundry detergents in the U. With regard to automatic dish detergents, phosphates have also been banned in several U. To see if certain products contain phosphates, try searching one of the following sources:.Supplier Discovery.

Prevent entry into waterways, sewers, basements or confined areas.With an accout for my. It is the sodium salt of triphosphoric acid. It is used in various applications such as a preservative for seafood, meats, poultry and pet foods. It is also used in toothpaste and as a builder in soaps and detergentsimproving their cleansing ability. Unfortunately, for consumers an excessive amount of STPP in food can cause an increase in price, for products sold by weight contain more water than products without STPP.

STPP is a solid inorganic compound used in a large variety of household cleaning products, mainly as a builder, but also in human foodstuffs, animal feeds, industrial cleaning processes and ceramics manufacture.

It also provides a number of chemical functions including: sequestration of " water hardness ", enabling surfactants to function effectively; pH buffering ; dirt emulsification and prevention of deposition; hydrolysis of grease; and dissolving-dispersing dirt particles.

In foods, STPP is used to retain moisture.

Many governments regulate the quantities allowed in foods, as it can substantially increase the sale weight of seafood in particular. Many people find STPP to add an unpleasant taste to food, particularly delicate seafood. The taste tends to be slightly sharp and soapy and is particularly detectable in mild-tasting foods. The increased water holding properties can also lead to a more diluted flavor in the food. Due to its physico-chemical properties, STPP is not distributed or transported to the atmosphere, and thus is not expected to end up in soil via atmospheric deposition.

Because it is very water-solubleit is not significantly transferred to sewage sludge, and therefore to soil by sludge spreading. No environmental risk related to STPP use in detergents is indicated in soil or air. As an ingredient of household cleaning products, STPP present in domestic waste waters is mainly discharged to the aquatic compartment, directly, via waste water treatment plants, via septic tanks, infiltration or other autonomous waste water systems.

As STPP is an inorganic substance, biodegradation studies are not applicable. STPP thus ends up being assimilated into the natural phosphorus cycle. Reliable published studies confirm biochemical understanding, showing that STPP is progressively hydrolysed by biochemical activity in contact with waste waters in sewerage pipes and within sewage works and also in the natural aquatic environment. Because of this, and because of the only temporary presence of STPP in the aquatic environment due to hydrolysisno studies have been carried out to date concerning the chronic effects of STPP on these aquatic organisms.

PNEC Predicted No Effect Concentrations were therefore calculated for the aquatic environment and sediments on the basis of the acute aquatic ecotoxicity results. Categories: Sodium compounds Phosphates.
