Problems solved by technology

Although the above-mentioned nanofibers have achieved a certain cosmetic effect, the base material of the mask is mostly non-woven fabric, the antibacterial agent is a chemical reagent, and the size of the nanofiber is different, so the air permeability of the prepared mask is quite different, which may cause users to be allergic

Abstract

The invention belongs to the field of skin-care mask materials, and discloses a plant cellulose nanofiber antibacterial moisturizing mask and a preparation method thereof. The preparation method comprises the following steps of hydrolyzing plant fibers by enzyme, and mechanically treating, so as to prepare plant cellulose nanofiber with a high length-to-radius ratio; blending antibacterial chitosan, other functional ingredient particles and the plant cellulose nanofiber, emulsifying to obtain a uniform and stable white emulsion which is used as a mask raw liquid, pouring the mask raw liquid into a die, and preparing a mask sheet with a specified shape under certain conditions; finally, filling feeding a wetting agent into a package bag of the mask body containing the plant cellulose nanofiber and the functional ingredients, sealing an opening, sterilizing, and packaging. The plant cellulose nanofiber antibacterial moisturizing mask has the advantages that by adopting pure natural plantfibers, the poison and harm are avoided, the safe, economical and environment-friendly effects are realized, the water is favorably supplemented to the deep skin layer, and the absorbing speed and absorbing effect of a functional nutritional liquid are improved.

Description

technical field [0001] The invention belongs to the field of skin care mask materials, and in particular relates to a plant cellulose nanofibril antibacterial and moisturizing mask and a preparation method thereof. Background technique [0002] Mask is a category of skin care products and a carrier of beauty care products. Its most basic and important purpose is to make up for the insufficient cleaning work of makeup remover and face wash. On this basis, it cooperates with other essence ingredients to achieve other maintenance functions. , such as moisturizing, whitening, anti-aging, balancing oil and so on. At present, masks made of powder blending, kaolin, non-woven fabrics, silk masks, tencel masks, biocellulose masks, and non-woven mask materials are widely used. With the improvement of people's living standards, consumers have higher requirements for facial masks, which are safe and environmentally friendly, and facial masks with high absorption of nutrient solution ar...
