Sodium tripolyphosphate CAS#7758-29-4

Sodium tripolyphosphate is a kind of excellent detergent additives, the largest amount of detergent in the production process is set, its role has four aspects:
1. the effect of heavy metal ion chelate: heavy metal ions in the process of washing water, can combine detergent molecules to form insoluble metal salt,reduce the washing ability, even complete loss of function. Therefore, it is necessary to add chelating agent, which can make water containing heavy metal ions into harmless substancesin the detergent. Sodium tripolyphosphate has strong chelation for heavy metal ions, sealing them and eliminating the adverse effects on the washing. In addition, it can capture dirt contained various metals in washing process, playing the role of dissociation of dirt, used as soap synergist and preventing bar soap grease precipitation and bloom.
2. The dirt on his gum, emulsifying and dispersing effect: Dirt often contain body fluids (mainly protein and fat like substances), also contains the sand from the outside world, dust etc.. Sodium tripolyphosphate has the expansion, solubilization on dirt protein, and the effect of the glue solution; emulsification of fat promotes; has dispersing effect on solid dirt, strong emulsification of lubricating oil and fat, can be used to adjust the pH value of buffer liquid soap.
3. prevent caking of detergent: Synthetic detergent powder is hygroscopic, such as stored in high humidity areas, it is necessary to caking phenomenon. Using detergent agglomerates is inconvenient. While the water absorption of sodium tripolyphosphate formed the hexahydrate, with characteristics of dry. When there is extensive use of detergent formulations, it can serve to prevent caking phenomenon caused by moisture absorption, keeping dry granular of the synthetic detergent.
4. It has a larger buffer alkaline washing solution, pH value is maintained at about 9.4, which is conducive to the removal of acidic dirt.

Product Application Of Sodium tripolyphosphate CAS#7758-29-4

Sodium tripolyphosphate is a binder, stabilizer, and sequestrant that is mildly alkaline, with a pH of 10, and moderately soluble in water, with a solubility of 15g in 100ml of water at 25°C. It is used to improve the whipping properties of egg-containing angel food cake mix and meringues. It reduces gelling of juices and canned ham and tenderizes canned peas and lima beans. It is a moisture binder in cured pork and protects against discoloration and reduces shrinkage in sausage products. In algin desserts, it functions as a calcium sequestrant. Sodium tripolyphosphate is also termed pentasodium tripolyphosphate and sodium triphosphate.
