Detergent aids are commonly used in various cleaning products, whether they are household washing products or industrial washing products. Adding detergent additives can improve the ability of various components in the detergent to penetrate clothing fibers, as well as further clean other surfaces and materials. Sodium tripolyphosphate/STPP is an additive with this excellent performance.

Washing aid is actually a comprehensive effect of multiple actions such as softening water, dispersing, emulsifying, anti redeposition, and PH buffering. Sodium tripolyphosphate not only has excellent cleaning aid, but also has strong decontamination ability without detergent. When it is compatible with surfactants, its detergency greatly exceeds the simple superposition of the two, which has a synergistic effect on surfactants.

Therefore, in most factories, sodium tripolyphosphate is used in multiple fields in the production of detergent auxiliaries. What is the principle of adding sodium tripolyphosphate to detergent?

There are many types of detergent auxiliaries, of which sodium tripolyphosphate is one, and its components play a very important role.

One is the chelation of heavy metal ions: Heavy metal ions in water are used to combine with detergent molecules during the washing process to form insoluble metal salts, reducing the washing ability or even completely losing their effect. Therefore, it is necessary to add substances in the detergent that can make the heavy metal ions contained in the washing water harmless.

Sodium tripolyphosphate is an additive with this excellent performance and has a strong chelating effect on heavy metal ions, which can seal them up and eliminate their adverse effects on washing. In addition, it can also capture various metal components contained in the dirt and play a role in dissociating the dirt during the washing process.

Secondly, it has the effect of degumming, emulsifying, and dispersing dirt: sodium tripolyphosphate has the effect of expanding and solubilizing proteins in dirt, thereby achieving degumming effect; Promoting emulsification of fat; It has a dispersing effect on solid dirt.

Thirdly, it has a preventive effect on detergents from clumping: sodium tripolyphosphate can keep detergents in a dry and granular state, and has the effect of preventing clumping due to water absorption. In addition, sodium tripolyphosphate also has an alkaline buffer effect that is conducive to the removal of acidic dirt.
