The infant wet tissue prepared from the konjac flour and the plant essential oil is natural and non-irritating, can effectively improve infant skin discomfort symptoms such as diaper rash, oral rash, sudoral rash and the like, is more suitable for infants, can be completely biodegraded, and has no pollution to the environment.

In this embodiment, the base material of the baby wet wipe is formed by processing and molding konjac flour into a konjac fiber structure, wherein the glucomannan content in the konjac flour is not less than 90%. When the glucomannan content in the konjac flour is too low, the wet tissue can not be formed easily, or the konjac flour is easy to deform after forming, and the konjac flour with the glucomannan content of more than or equal to 90% is selected to ensure that the wet tissue can form a stable fiber structure during forming.

The plant essential oil comprises at least one of mei teng fruit oil, tea seed oil, jojoba oil, castor oil and shea butter. The essential oil extracted from various natural plants is natural and non-irritating, so that the skin-friendly property of the wet tissue is further improved, the symptoms such as allergy and the like are avoided, and the skin can be nourished.

The emulsifier comprises at least one of tween 20, tween 60, tween 80, lauric acid monoglyceride and lecithin. The emulsifier is added, so that the dispersibility and stability of the powdery raw materials and the purified water can be improved when the powdery raw materials and the purified water are mixed, a uniform and stable hydrogel solution is formed, and meanwhile, the Tween 20, the Tween 60, the Tween 80, the lauric acid monoglyceride and the lecithin are nontoxic and non-irritant raw materials, so that the stimulation effect of the prepared infant wet tissue on the skin of an infant in the use process can be avoided.

The cross-linking agent is sodium trimetaphosphate. In the process of heat preservation and forming of the hydrogel solution prepared in the step S10 in the mold, the konjac fibers in the konjac flour are formed into a stable reticular fiber structure under the action of the cross-linking agent, which is beneficial to improving the strength of the reticular fiber structure, and further meets the strength requirement of the prepared baby wet tissue in actual use.

In another embodiment provided by the present invention, step S10 includes:

step S11, adding the konjac flour into purified water, and stirring for the first time to form a konjac solution;

the first stirring is low-speed stirring, and the effect is to dissolve the konjac flour in purified water to form a konjac solution, wherein the rotation speed of the first stirring is 50-200 rpm/min.

Step S12, adding plant essential oil and emulsifier into the konjak solution, and stirring for the second time to form a micro-emulsified solution;

the second stirring is ultra-high speed stirring, and has the effects of achieving micro-emulsification through the ultra-high speed stirring, enabling the surface structure of the formed wet tissue to be compact and smooth, and enabling various plant essential oil components added in the formed wet tissue to form a compact oily surface layer on the surface of the wet tissue, so that the formed wet tissue is more suitable for tender and sensitive skin of infants. Wherein the rotation speed of the second stirring is 2500-5000 rpm/min.

Step S13, adding a gelling agent and a cross-linking agent into the micro-emulsified solution, and stirring for the third time to form a gel emulsion;
