Why Is Washing Powder With Biological Enzymes Better For Cleaning Clothes?

- Aug 10, 2020-

When our clothes are stained with oil, sweat or blood, it is difficult to clean them with ordinary washing powder. To solve this problem, scientists have developed a more effective washing powder.


The ingredients of common washing powders can be briefly summarized as: surfactants, buffers, builders, synergists and auxiliary materials. Surfactants have hydrophilic and lipophilic groups, which can be aligned on the surface of the solution and weaken the adhesion between stains and clothes. Buffer is one of the most important raw materials of washing powder. The decontamination ability of washing powder will be improved in an alkaline environment, and the buffer can provide a proper alkaline washing environment. Commonly used buffers are: carbonate, silicate, etc. Washing powder generally contains a variety of builders, whose role is to meet different functional requirements, such as improving the decontamination ability and improving the anti-redeposition performance of the washing powder, which can enhance the comprehensive performance of the washing powder.


Ordinary washing powder has limited decontamination ability. For this reason, scientists have developed washing powder with biological enzymes. Enzyme-added laundry detergent has strong decontamination ability and is more environmentally friendly than ordinary laundry detergent.


Enzyme washing powder refers to washing powder containing enzyme preparations. Currently, there are four types of enzyme preparations commonly used: protease, lipase, amylase and cellulase. Among them, alkaline protease and alkaline protease are the most widely used and the best decontamination effect. Alkaline lipase. Protease can hydrolyze macromolecular proteins in blood stains, milk stains and other stains into soluble amino acids or small molecular peptides, making them easy to fall off clothes; lipase can hydrolyze macromolecular fats in oil stains into small molecular substances; starch; Enzymes can hydrolyze large molecules of starch into small molecules; cellulase can hydrolyze cellulose into small molecules.


Enzyme-added detergent has stronger decontamination ability than ordinary detergent due to the presence of enzymes, but enzymes have higher environmental requirements. Temperature, pH and surfactants will all affect the decontamination effect of enzyme-added detergent. In order to make enzymes have better activity in washing powders, scientists have produced enzymes that are resistant to acids, alkalis and higher temperatures through genetic engineering, and use special chemicals to wrap the enzymes in layers. The other components of the isolation layer are isolated, and this isolation layer will quickly dissolve after encountering water, and the enzymes wrapped in it can quickly play a catalytic role.
