Cream tissues are usually in direct contact with the skin, so they have high requirements for the softness, smoothness and smell of the paper. The moisture content of cream tissues is a key indicator of its softness and smoothness. The moisture content of ordinary tissues on the market is about 10%, while the moisture content of cream tissues is 20-30%, and the tissues will lose moisture quickly as the environment changes. Summary of the invention

[0011] S4. After the reaction is completed, the temperature is lowered to 40 ° C, and the emulsifier, guar gum, and 1-3 propylene glycol are sequentially added to the dispersion kettle;

[0012] S5. Add glycerol into the dispersion kettle through a pump, control the addition time to be 30 minutes, and after the addition is completed, continue stirring for 60 minutes to obtain an emulsified cream with high moisturizing performance.

[0013] Furthermore, in the preparation method, 60 parts of glycerol, 1 part of benzyl pyridinium chloride, 1 part of C12-14 secondary alcohol polyvinyl ether and 1 part of dialkyl dimethyl quaternary ammonium salt as emulsifiers, 0.1 part of nanocellulose, 2 parts of 1-3 propylene glycol, 0.05 part of guar gum, and 40 parts of deionized water are included.

[0019] Glycerol is the main raw material in the formula, which provides excellent moisturizing performance and absorbs moisture in the air; the emulsifier C12-14 secondary alcohol polyvinyl ether is a nonionic surfactant, and the dialkyl dimethyl quaternary ammonium salt is a cationic surfactant (the purpose of using the cationic surfactant and the nonionic surfactant is to increase the stability of the product, the cationic surfactant can be firmly adsorbed on the negative charge on the surface of the paper towel, and the dialkyl dimethyl quaternary ammonium salt can provide a certain softness for the paper towel), which is mainly used for emulsifying glycerol and water to form an oil-in-water structure and provide a certain softness; guar gum provides a certain viscosity and reduces the irritation of the surfactant; benzyl chloropyridinium salt is also a cationic surfactant, and the nanocellulose is modified by the benzyl chloropyridinium salt so that it has a positive charge to improve its stability in the whole system, and the porous structure and cationic stability of the nanocellulose are utilized to better lock moisture, and the moisturizing and water-retaining performance of the cream can be effectively improved; 1-3 propylene glycol also has moisturizing performance and a certain antibacterial property.
