In the invention, the following four substances are used as the moisturizers of the moisturizing cream special for the living paper:

the isomaltitol can effectively prevent the effective components of the moisturizing cream from being separated out in a low-temperature environment, and has the function of preventing the breeding of microorganisms, and the isomaltitol is odorless slightly sweet powder.

The xylitol moisturizing cream not only has the moisturizing function, but also can make the cream feel cool after being applied to living paper. Xylitol is an odorless, refreshing, sweet powder.

Trehalose has a strong water-retaining effect in moisturizing creams, is also called as life sugar, can maintain the activity of protein under the condition of extreme water loss of organisms, and is odorless and has cool sweet taste.

Glycerol is used as an auxiliary water-retaining agent in the moisturizing cream, and is odorless slightly sweet solution.

The triglycerin is a food-grade emulsifier, and is used for dispersing and solubilizing monomers to form a relatively stable monomer emulsion and provide a place for monomer polymerization or reaction; the latex particles are stabilized against coagulation to form a stable polymer emulsion having a certain solids content and viscosity. Compared with the conventional emulsifier, the polymerizable emulsifier has the characteristics of hydrophilicity, lipophilicity and stability. The preparation method of the triglyceryl ester is that three glycidol polymers are subjected to esterification reaction with fatty acid. Compared with other cream formulas using glycerin in the market, the triglycerin has stronger emulsifying function.

Wherein the softening agent with high polymerization degree is selected from R-550N. Compared with the traditional organic silicon softening agent, the Nippon chemical R-550N is the methyl-free silicone and epoxy ketone, so that the whiteness of a fiber carrier used by the softening agent is not damaged. R-550N is an organic silicon hydroxyl softening agent, and a molecular chain at the tail end of the organic silicon hydroxyl softening agent has hydroxyl, so that the improvement of the hydrophilicity and the emulsion stability is facilitated to a certain extent.

Wherein the regulator is selected from plant pH regulator such as tea polyphenols. The pH value of the cream is controlled by weak acid and weak base from plant sources, so that the pH value of the cream is kept neutral, and the salt substance reaction on the living paper after the cream is sprayed on the living paper is reduced as much as possible. The tea polyphenol has different inhibition and killing effects on a plurality of pathogenic bacteria such as proteus, staphylococcus aureus, staphylococcus epidermidis, streptococcus mutans, clostridium botulinum, lactobacillus, vibrio cholerae, oral mutans bacteria and the like, especially on intestinal pathogenic bacteria, and is one of the important components of the natural preservative of the moisturizing cream special for the living paper.

Wherein the stabilizer is selected from system stabilizers of emulsions: persimmon extract.

The functional factors are selected from one or more of moisturizing factors, whitening factors and antioxidant factors.

The moisturizing factor is selected from hyaluronic acid, has strong hydrophilicity, is a natural moisturizing agent, and can resist invasion of bacteria and foreign substances.

The whitening factor is selected from nicotinamide, and its nicotinic acid content is controlled within 20 ppm.

The antioxidant factor is selected from water-soluble vitamin E, helps to prevent polyunsaturated fatty acid and phospholipid from being oxidized, can maintain the integrity of cell membrane, and is a very effective antioxidant from natural sources.
