laundry detergent without enzymes?

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. It is biological washing powder.

The ingredients of common washing powder can be simply summarized as surfactant, buffer, washing aid, synergist and auxiliary materials. Surfactants have hydrophilic and lipophilic groups, which can be aligned on the surface of the solution and reduce 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, while buffer can provide an appropriate alkaline washing environment. Commonly used buffers include carbonate, silicate, etc. Washing powder generally contains a variety of washing AIDS, which are used to meet different functional requirements, such as improving the decontamination ability and anti-redeposition performance of washing powder, which can improve the comprehensive performance of washing powder.

Ordinary washing powder has limited decontamination ability. Therefore, scientists have developed washing powder with biological enzymes. Enzymatic detergent not only has a strong decontamination ability but also is more environmentally friendly than ordinary detergent.

Enzyme added detergent refers to the detergent containing enzyme preparations. At present, there are four types of enzyme preparations commonly used: protease, lipase, amylase and cellulase, among which alkaline protease and alkaline lipase are the most widely used and have the best decontamination effect. Protease can hydrolyze macromolecular proteins in bloodstains, milk stains and other stains into soluble amino acids or small molecular peptides, making them easy to fall off from clothes; Lipase can hydrolyze macromolecular fat in oil stains into small molecules; Amylase can hydrolyze macromolecular starch into small molecules; Cellulase can hydrolyze cellulose into small molecules.

Enzymatic detergent has a stronger decontamination ability than ordinary detergent because of the existence of enzymes, but the enzyme has higher requirements for the environment. Temperature, pH and surfactant will affect the decontamination effect of enzymatic detergent. In order to make the enzyme have better activity in the washing powder, scientists have produced an enzyme that can withstand acid, alkali and high temperature through genetic engineering, and use special chemicals to wrap the enzyme layer by layer and isolate it from other components in the washing powder. This isolation layer will dissolve quickly when it meets water, and the enzyme wrapped in it can quickly play a catalytic role.
