preparation example 1

[0048] 1) Reaction of octadecyl dimethyl tertiary amine with epichlorohydrin and hydrochloric acid:

[0049] The dry hydrogen chloride gas was introduced into the anhydrous ether solution of octadecyldimethyl tertiary amine to produce white precipitate. Then use water as the solvent, put a certain amount of epichlorohydrin in the dropping funnel, start to drop it slowly, drop it in 35 minutes, stir evenly at room temperature, react at 80°C for 12h, and titrate the epichlorohydrin quaternary ammonium After the reaction was completed, the solvent was removed by rotary evaporation at room temperature to obtain a light yellow paste residue, which was recrystallized with acetone, filtered under reduced pressure after the crystals were precipitated, and repeated several times. Obtain white powder single quaternary ammonium salt product---intermediate product N-(3-chloro-2-hydroxypropyl)-N,N-dimethyl octadecyl ammonium chloride.

[0050]

[0051] 2) Reaction process: Methyl oleat...

preparation example 2

[0059] Same as Preparation Example 1, the only difference is that in the 1) step, anhydrous diethyl ether solution of dodecyldimethyl tertiary amine is used to finally obtain 2-triethoxysilyl propaneoxy-1-N,N -Dimethyloleoyl-3-dodecyldimethylammonium propane dichloride (abbreviation: organosilicon bisquaternary ammonium salt B), the yield is 98.5%.

Embodiment 1

[0062] The preparation method of the wet wipe body is as follows:

[0063] (1) adopt length to be 40mm, the bamboo pulp fiber that diameter is 0.08mm is as raw material, through weighing, cotton blending, opening, mechanical carding, messy web laying process, make it form fiber web;

[0064] (2) 10 water needles formed by high-pressure fine water flow are used to puncture the front and back sides of the fiber web respectively, so that the fiber web is completely soaked, and the fiber web is entangled and reinforced; the fine water flow is 0.5% organic The aqueous solution of silicon double quaternary ammonium salt A;

[0065] (3) Then place it at a temperature of 120°C for cross-linking and drying for 8 minutes;

[0066] (4) After cutting and high-temperature sterilization, the non-woven wet tissue body with a thickness of 5 mm is obtained;

[0067] In the preparation process of the wet wipe liquid E, the solution A is 0.35 g of polysorbate-60, 0.1 g of polyglyceryl-2 oleate...

Abstract

The invention relates to a physical antibacterial wet tissue. The physical antibacterial wet tissue comprises a wet tissue body and wet tissue liquid, and is characterized in that the wet tissue body is made of an antimicrobial membrane or nanoparticle nonwoven cloth with positive charges; the antimicrobial membrane or the nanoparticle is formed by chemical bond combination ; the wet tissue liquid selects RO (reverse osmosis) pure water, a surfactant, a skin moisturizing agent, a skin conditioning agent and other additives; then, ozone with concentration of 0.1 to 1.0mg/L is introduced into the wet tissue liquid; finally, the wet tissue liquid is added into the wet tissue body according to a certain weight ratio, and then the wet tissue body is sealed and packaged, so as to obtain the physical antibacterial wet tissue. The physical antibacterial wet tissue is a wet tissue with zero separation of preservative, is soft to skin, is free from irritation and allergy, and is especially suitable for allergic skins, tender skins and the like.

Description

technical field [0001] The invention relates to a physical antibacterial wet tissue, in particular to a baby buttock wet tissue. Background technique [0002] In recent years, because the application of wet wipes has brought convenience to people's lives and has gradually become a necessity in people's lives, the annual output and consumption of wet wipes have grown rapidly, and the application fields of wet wipes have continued to expand , the corresponding product development requirements are getting higher and higher. At present, there are many types of wet wipes, such as hand and mouth wipes, sanitary wipes, makeup remover wipes, skin cleansing wipes, etc. With the continuous expansion of the market scale, the national industrial policy encourages the wet wipe industry to move towards high-tech and high value-added The development of product direction will improve product competitiveness and market share, so the development of wet wipe formulation technology will play a...
