Information recommendation Explain the introduction of weak alkaline liquid washing powder

The pH value of weak alkaline liquid washing powder is between 9 and 10.5, and some products are mixed with sodium alkyl benzene sulfonate sustained-release tablet and fatty alcohol polyoxyethylene ether, and carbonate is added to change the pH value. The detergent is made of high-foaming liquid laundry detergent. The common nominal active agent of weak alkaline liquid laundry detergent is alkyl benzene sulfonic acid... The pH value of weak alkaline liquid washing powder is in the range of 9 to 10.5, and some products use alkyl benzene sulfonic acid. Sodium handleate sustained-release tablet is mixed with fatty alcohol polyoxyethylene ether, and carbonate modifier is added to make high-foaming liquid washing powder. The common nominal active agent of weak alkaline liquid laundry detergent is sodium alkyl benzene sulfonate, which has good decontamination effect and strong water resistance, and is very easy to dissolve in water. The detergency of such nominal active agents in hard water becomes weaker with the development of strength, so antioxidants need to be added to remove calcium and aluminum ions. When using polyphosphates as antioxidants in liquid laundry detergents, potassium pyrophosphate is mostly used. Its chelation ability to calcium and aluminum ions is not as good as that of sodium tripolyphosphate, but it is very soluble in water. In addition, some liquid washing powders require a certain viscosity and pH value, so inorganic and organic chemical binders and solubilizers are also added. At pH 7 to 8, it can be used to clean silk, wool and other delicate textiles. This product is mainly composed of nominal active agent and solubilizer. Since there is no modifier, the detergency depends mainly on the nominal active agent, so the content of the nominal active agent is relatively high, some 40% to 40%. Some non-cationic nominal active agents are higher than cationic nominal active agents in specific content. Due to the high content of non-positive ion nominal active agent, it is easy to cause the growth of bacteria, and even the product will fade and smell. additive.
