Propylene glycol is used in the antibacterial liquid to maintain the moisture of the wet wipes, interfere with the cell wall synthesis of microorganisms, destroy their metabolic pathways, thereby inhibiting the growth and reproduction of bacteria and playing a certain antibacterial role; at the same time, sodium lactate can destroy the bacterial cell membrane structure, cause the protoplasm to flow out of the body, inhibit the synthesis of intracellular ATP, accumulate lactic acid molecules in the cells, lower the pH value, acidify the cytoplasm, and inhibit bacterial growth; silver ions, as cations, are easily adsorbed by anionic bacteria, enter the bacteria, interfere with the synthesis of bacterial cell walls, and destroy the structure and function of microbial cells; eucalyptus leaf extract also contains natural antibacterial ingredients that can inhibit bacterial reproduction, and cooperates with phenoxyethanol to maintain the activity of the effective substances in the liquid; when using wet wipes, these antibacterial ingredients can pass through the moisture-locking layer 2, the permeation layer 3 and the skin-friendly layer 4 to contact the human skin, playing a good antibacterial effect.

[0020] Reference Figure 1 and Figure 2The antibacterial agent is composed of a mixture of 50-70 parts of ethanol, 5-7 parts of ammonium chloride, 3-5 parts of benzoic acid and 1-4 parts of chlorhexidine gluconate; specifically, in the moisture-locking layer 2 impregnated with the antibacterial agent, ethanol can penetrate the microbial cell membrane, destroy its structure, cause the cell contents to leak, combine with the microbial protein, denature and inactivate it, thereby inhibiting the growth of microorganisms; and ammonium chloride may inhibit bacterial growth by interfering with the metabolic process of microorganisms, such as affecting enzyme activity or cell wall synthesis; benzoic acid can interfere with bacterial cell wall synthesis, destroy the cell membrane, affect the integrity of the fungal cell membrane, and inhibit its normal metabolism; at the same time, chlorhexidine gluconate can adsorb on the permeability barrier of the bacterial cytoplasmic membrane, destroy the bacterial cell structure, cause the cell contents to leak out, thereby enhancing the antibacterial effect; when using wet wipes, the antibacterial liquid will drive the antibacterial components impregnated on the moisture-locking layer 2 to contact with the skin when passing through the moisture-locking layer 2, further enhancing the antibacterial effect.

[0021] Reference Figure 1 and Figure 2 The permeable layer 3 is made of either wood pulp fiber or bamboo pulp fiber; specifically, the wood pulp fiber or bamboo pulp fiber has a porous mesh structure, which makes the fiber have good moisture absorption and air permeability, and also provides space for penetration and storage of the liquid medicine, thereby improving the permeability of the liquid medicine and ensuring that it can penetrate the moisture lock layer while maintaining its antibacterial and skin care effects; the skin-friendly layer 4 is woven from a mixture of cotton fiber and bamboo fiber; specifically, bamboo fiber is soft, environmentally friendly, and has good water absorption. The water absorption and softness of wood pulp fiber are both good, and the environmental protection is good. Blending cotton and bamboo to form the skin-friendly layer 4 can combine the advantages of cotton and bamboo, and can improve the water absorption and softness of the wet wipes.
