Sodium tripolyphosphate buffer
STPP weakly alkaline aqueous solution (PH value of 1% aqueous solution is approximately 9.7), which in the PH range is 4.3-14 water) to form a suspension (similar emulsion) role, namely dispersion.
Sodium tripolyphosphate can also liquid and solid particles in a liquid and better (e.g., water) medium, the appearance of the solution was completely transparent, as if a true solution, which is solubilizing effect.
Because sodium tripolyphosphate with more unique properties, making it an important detergent ideal raw material.
