Disinfection emulsion, preparation method thereof and disinfection wet tissue prepared by using disinfection emulsion

Abstract

The invention discloses a disinfection emulsion, a preparation method thereof and a disinfection wet tissue prepared from the disinfection emulsion. Raw materials of the disinfection emulsion comprisethe following components in parts by weight: 0.5-5 parts of polyhexamethylene biguanide, 2-10 parts of a film-forming agent, 1-5 parts of a nonionic surfactant, 1-10 parts of a cationic surfactant and 50-200 parts of deionized water. The nonionic surfactant and / or the cationic surfactant contains a fatty alcohol group, and the carbon chain of the fatty alcohol group is C10-C18; the film-forming agent is selected from one or more of methyl laurate, tridecanol, hexadecanol, octadecanol and propylene glycol phenyl ether. The disinfection emulsion disclosed by the invention has the advantages ofgood stability, capability of automatically forming a film on a low surface and automatically expanding to form a film, long shelf life, good sterilization persistence and high safety, so that a disinfection wet tissue product prepared from the disinfection emulsion also has corresponding characteristics.

Description

technical field [0001] The invention relates to a dynamic and static sealing device, in particular to a disinfectant emulsion, a preparation method thereof, and a disinfectant wet tissue prepared by using the same. Background technique [0002] Polyhexamethylene biguanide (international common name: PHMB) is a safe, efficient and broad-spectrum polymer antimicrobial agent, widely used in the field of sanitation and disinfection. When the current disinfectant is used, it basically adopts the method of artificial spraying. Due to the large particle size of the sprayed droplets, generally 100-400 microns, the droplets are basically unable to disperse, and a certain area of ​​​​area needs to be fully covered. , which is often difficult in places with hygienic dead ends. Moreover, even if the existing aerosol containing polyhexamethylene biguanide is atomized into a small particle size aerosol, due to the poor water retention performance of the formed mist droplets, it will caus...

Problems solved by technology

[0004] But, first of all, because the existing disinfectant solution, especially the disinfectant solution containing polyhexamethylene biguanide, is an aqueous system, for a pure liquid, the surface tension of water is the largest among common liquids

At 20°C, the surface tension of water is 72.75mN / m, while the surface tension of alkanes is relatively small. For example, the surface tension of n-octane is 21.80mN / m at 20°C, and the surface tension of nylon-66 is 46.0mN / m. The surface tension of PVC is 39.0mN / m, and the surface tension of polystyrene is 33.0mN / m. Due to the popularity of plastic products, there are a large number of surfaces with low surface tension in people's living places, and the existing water-based disinfectants basically cannot Spreading on the surface of objects with low surface tension, it is easy to slide off these surfaces, so it cannot meet the needs of people now; secondly, the existing disinfectant has insufficient adhesion on the surface of objects due to high surface tension, and is not resistant to rainwater erosion; Again, because the area that needs to be disinfected in life may be too large, and there may be dead ends in hygiene, it is impossible for people to use wet wipes for disinfection to be comprehensive. A disinfectant that can automatically expand and form a film has become a more urgent need.
