Sodium tripolyphosphate is the best inorganic additive for washing

The main ingredients of synthetic detergents are surfactants, which are wetted, permeable, emulsified, dispersed and frothing. The effect of decontamination is a part of the combination of these effects. Although it has the effect of decontamination, it is not satisfactory in all cases, such as poor effect in hard water, poor feeling, high price, good washing effect, high pH, but high pH will corrode washing machine and washing machine and so on. The synthetic detergent has good washing property. The effect is good and has good washing effect. With better suitability, detergent additives must be added to become the washing products that people like to use. Auxiliaries have organic and inorganic additives, and different auxiliaries have different functions. Organic additives such as carboxymethyl fiber or methyl cellulose can prevent scaling and redeposition; inorganic additives include sodium carbonate, sodium tripolyphosphate, sodium pyrophosphate, sodium silicate, sodium sulfate and so on. These inorganic additives can reduce the critical micelle concentration of synthetic detergents. Combined with micellar concentration, synthetic detergents can be washed at lower concentrations. In addition, these inorganic additives can also improve the detergency effect of synthetic detergents in alkaline detergent, and sodium tripolyphosphate is the best inorganic additive.
