[0008] By setting the above technical scheme, the chloro-m-dimethyl phenol can denature the protein of bacteria, thereby playing a role of sterilization and disinfection. Ethanol and isopropyl alcohol are both organic solvents, and have good sterilization effect. They can rapidly dehydrate bacterial cell membranes and denature proteins, thereby killing bacteria. Meanwhile, ethanol and isopropyl alcohol can also dissolve some lipid-soluble microorganisms, thereby enhancing the disinfection effect and having certain volatility, which is helpful for rapid drying of clothes. Terpineol has certain sterilization, disinfection and deodorization effects, and eucalyptus extract has antibacterial and antiviral effects. They can not only enhance the disinfection effect, but also impart a fresh smell to clothes. Monoethanolamine can adjust the pH value of the solution, so that the disinfectant is in a suitable pH range, which is helpful for improving the sterilization effect and stability, and also has certain corrosion inhibition effect on some metals, thereby reducing damage to clothes. Fragrance is used to improve the smell of the disinfectant and mask the bad smell of other components, so that clothes have a pleasant smell after disinfection.

[0009] Preferably, the surfactant consists of sodium fatty alcohol ether sulfate and narrow distribution fatty alcohol polyoxyethylene ether-7, and the sodium fatty alcohol ether sulfate accounts for 3-8% and the narrow distribution fatty alcohol polyoxyethylene ether-7 accounts for 1-3% by total weight.

[0015] 2) Add deionized water according to the mass ratio of eucalyptus leaves to water 1:4-1:5, slowly stir to evenly disperse the eucalyptus leaves in the water;

[0016] 3) Connect the distillation device, heat to boiling of deionized water, control the distillation temperature to be 100-105℃, the water vapor generated carries the steam of eucalyptus leaf extract, which is cooled by the condenser tube to form an oil-water mixture and drops into the receiver;

[0017] 4) Stop heating when no oil phase is precipitated from the condenser tube for 10 minutes, stand for 24h, use the separatory funnel to take the upper clear liquid, and the eucalyptus leaf extract is obtained.

[0018] Preferably, in step 1), the washed eucalyptus leaves are placed in a cool, ventilated place and dried to a moisture content of ≤15%.

[0019] By setting the above technical solution, the volatilization loss of eucalyptus oil in eucalyptus leaves caused by direct sunlight can be avoided.

[0020] Preferably, in step 3), when heating the deionized water, heat the distillation flask at a speed of 3℃ / min.

[0021] By setting the above technical solution, the probability of affecting the normal extraction of eucalyptus leaves due to local overheating can be effectively reduced.

[0031] The present application has the following advantages:

[0032] p-Chlorometacresol can denature the protein of bacteria, thus playing a role in sterilization and disinfection. Ethanol and isopropyl alcohol are organic solvents, and have good sterilization effect. They can rapidly dehydrate the cell membrane of bacteria, denature the protein and coagulate, thus killing the bacteria. Meanwhile, ethanol and isopropyl alcohol can also dissolve some lipid-soluble microorganisms, enhance the disinfection effect, and have certain volatility, which is helpful for rapid drying of clothes.

[0033] Terpineol has certain sterilization, disinfection and deodorization effects, and the eucalyptus oil in eucalyptus extract has antibacterial and antiviral effects. They not only can enhance the disinfection effect, but also can impart a fresh smell to clothes. Monoethanolamine can adjust the pH value of the solution, so that the disinfectant is in a suitable pH range, which is helpful for improving the sterilization effect and stability, and also has certain corrosion inhibition effect on some metals, reducing the damage to clothes. Essence is used to improve the smell of the disinfectant, and to cover the bad smell brought by other components, so that the clothes have a pleasant smell after disinfection.

[0034] Sodium fatty alcohol ether sulfate has good detergency, emulsification and foaming properties, can reduce the surface tension of water, so that the disinfectant can better penetrate into the fibers of clothes, remove stains, and help the sterilization components to fully contact with bacteria. Narrow distribution fatty alcohol polyoxyethylene ether-7 has excellent emulsification, dispersion and wetting properties, can make other components better dispersed and uniform in water, and improve the stability and use effect of the disinfectant.

[0035] Ethanol, isopropyl alcohol, sodium fatty alcohol ether sulfate and narrow distribution fatty alcohol polyoxyethylene ether can form a stable, transparent and uniform aqueous solution of p-chlorometacresol. DETAILED DESCRIPTION
