Sodium tripolyphosphate is among the substances which are synthesized for a plethora of purposes in the cleaning, food and ceramics industry. In essence, one can say that the sodium tripolyphosphate or STTP for short is basically sodium saline derived from triphosphoric acid. The formula for this amalgam is Na5P3O10 and can be obtained by mixing disodium phosphate with the monosodium phosphate in a stable and restricted setting. Due to its many practical uses, the specialized industry manufactures roughly 2 tons on a year basis. In the form of powder, the sodium tripolyphosphate will require a temperature of over 622 degrees Celsius to melt, but the substance can be easily dissolved in water.
In its pure form, sodium tripolyphosphate appears like a coarse powder colored in a white shade. It is worthy to note that the substance can also come in the form of a white crystal. There are basically two types of sodium tripolyphosphate and the transition between the second type and the first one can be achieved after subjecting it at a temperature of 500 to 600 degrees Celsius. In practice however, you should expect products that contain sodium tripolyphosphate to be in the form of gels, liquids and tablets as well, depending on their function.
The sodium tripolyphosphate does present a low level of alkalinity, but the good news is that it is not related to corrosion. It dissolves in water very easy and once it did so it acts as a booster for the surfactants as well as water softener. The molecular mass for the sodium tripolyphosphate is 367.86. Furthermore, the sodium tripolyphosphate is quite effective in transforming suspension substances into clear substances. Storing sodium tripolyphosphate require a moisture-free environment. It is also important to note that this compound will boost the effectiveness of detergent agents in water with high concentrations of magnesium and calcium. In order to understand the problems experienced by the detergent in the aforementioned type of water, one needs to consider that these substances work to deactivate and unbind the particles. However, thank to the charged chelating properties, the sodium tripolyphosphate is able to rebind them and consequentially, eliminate the interference caused by hard water.
As mentioned, sodium tripolyphosphate presents a plethora of uses associated with it. The first and most common use comes from the cleaning product industry. It is worth mentioning that it is used both in industrial-power cleaning substances and in the common ones you can see among the household. The main grounds for the popularity of the sodium tripolyphosphate reside in its ability to boost the effectiveness of the surfactants present in the detergents. This means that the cleaning products that include it will not only be capable of removing stubborn particles of dirt, but they will also make it more difficult to stick to the surfaces in the future. Furthermore, sodium tripolyphosphate will buffer the PH of the water. As a side note, the substance is highly appreciated in the composition of toilet cleaning products.
Next off, sodium tripolyphosphate is used in the food preservatives industry. The reason for this is that the substance is very capable of maintaining the moisture level of certain foods for extended periods of time and creates a shield against microorganisms. It is worth noting that sodium tripolyphosphate is employed in preserving both human and pet food. Moreover, the preservative industry also includes this substance to natural juices and milk.
A similar attractiveness is presented by the sodium tripolyphosphate in the paint, ceramics and paper industry. The clay employed in the ceramics as well as the paint composition experience an enhanced dispersion and therefore a better consistency. For the paper industry, on the other hand, the benefits of sodium tripolyphosphate come from the oil-resilient coating.
Sodium tripolyphosphate can be considered a substance with a high versatility in terms of usage in a great array of industries. Its main powder or crystal forms present a very high melting point and high water solubility. It is advisable to avoid inhaling vapors resulted from sodium tripolyphosphate compounds or ingesting the substance, as tests performed on it have revealed negative consequences related to these mishaps. In addition, ensuring the proper ventilation in the storage room is essential.
