What is the role of sodium tripolyphosphate in detergents? The manufacturer tells you
Sodium tripolyphosphate is an indispensable assistant in detergent. The content of most detergents is 10%-50%. What is the role of sodium tripolyphosphate in detergents ? The manufacturer tells you. The role of sodium tripolyphosphate in detergents is summarized as follows: 1. Chelation of metal ions: Hardening metal ions (mainly Ca2+, Mg2+) are commonly found in daily washing water. In the process of washing, they will form insoluble metal salts with the active substances in soap or detergent, which will not only increase the consumption of detergent, but also make the washed fabric have unpleasant dark grey. Sodium tripolyphosphate has excellent properties of chelating hard metal ions, thus eliminating the adverse effects of these metal ions. 2. Buffering effect: Sodium tripolyphosphate has a greater alkaline buffer effect, keeping the pH value of washing solution at about 9.4, which is conducive to the removal of acid fouling. 3. Improve the role of sol, emulsification and di...
