Sodium tripolyphosphate, sodium tripolyphosphate best lowest price

Sodium tripolyphosphate is indispensable excellent detergent additives, most of the detergent in an amount of 10-50%. Its main role can be summarized as follows: 1 chelating metal ions: the daily wash water, generally contain organic hard metal ions (mainly ca2 + mg2). During the washing process, they will form insoluble salts with soap and detergent actives, this is not only to increase the consumption of detergents and washed fabrics make an unpleasant dark gray. Sodium tripolyphosphate having a hard metal ion chelated organic excellent performance, which can eliminate the adverse effects of these metal ions. 2 increase peptization, emulsification and dispersion effects: dirt often contain human body secretions (mainly proteins and fatty substances), also contains from outside sand, dust and the like. The sodium tripolyphosphate to proteins with swelling, solubilization and play peptization effect; for fatty substances can play a catalytic role in emulsification; there are dispersed solid particles suspended effect. 3 buffer: sodium tripolyphosphate having a large alkaline buffer, ph value of the washing solution was maintained at about 9.4, thereby facilitating the removal of acidic soils. 4 to prevent caking role: powdered synthetic detergent is hygroscopic, such as stored in high humidity areas, to happen agglomeration. Caked detergent is extremely inconvenient use. While sodium tripolyphosphate hexahydrate absorbent formed after having dry properties. When there is a lot of detergent formulations tripolyphosphate when you can play to prevent caking phenomenon caused due to moisture absorption, keeping dry granular synthetic detergent.
