A kind of ultra-thin facial mask paper with high water retention and high softness and its preparation method and application

Abstract

The invention discloses ultrathin facial-mask paper with high water retention and high softness, a preparation method and application thereof. The method comprises the following steps of: (1) placingplant-fiber paper pulp into buffering solution to soak for 1-48 hours, then washing to be neutral, then adding water to dilute, and obtaining plant-fiber paper pulp I, wherein the buffering solution is aqueous mixed solution of citric acid and sodium hydroxide, and the mass concentration of the plant-fiber paper pulp I is 0.1%-5%; (2) adopting an ultrafine-particle crusher to crush the plant-fiberpaper pulp I obtained in the step (I), and obtaining cellulose nanofibril; (3) adding a softening agent into the cellulose nanofibril obtained in the step (2), carrying out paper making and drying after uniformly stirring and mixing, and obtaining the ultrathin facial-mask paper with high water retention and high softness. The ultrathin facial-mask paper disclosed by the invention has the beneficial effects that base materials with biodegradability are adopted, so that no influence is caused on the environment, and the prepared facial-mask paper not only has good air permeability and softness, but also has excellent water retention and adsorbability.

Description

technical field [0001] The invention belongs to the field of cosmetics, and in particular relates to a super-thin facial mask paper with high water retention and high softness, its preparation method and application. Background technique [0002] With the improvement of people's living standards, the requirements for beauty are getting higher and higher, and women are more interested in beauty care products. Because of its high nutritional content and remarkable skin care effect, facial masks have become the most important part of skin care products, which has given birth to people's deeper research on facial masks. [0003] Chinese patent application No. 2012101905524 has announced "manufacturing method of mask paper and beauty skin care paper mask and mask". The method is based on wood fiber, bamboo fiber and grass fiber, adding nutrient solution and wet strength agent to improve wet strength It retains water, makes the skin moist and transparent, and glows with natural b...

[0003] Chinese patent application No. 2012101905524 has announced "manufacturing method of mask paper and beauty skin care paper mask and mask". The method is based on wood fiber, bamboo fiber and grass fiber, adding nutrient solution and wet strength agent to improve wet strength Water retention, make the skin moist and transparent, and glow with natural brilliance, but the increase in wet strength is not obvious, and there is a lack of direct data support

Chinese patent application No. 2016210258688 discloses "a mask paper and its mask", which specifically relates to a theoretical design of the contour structure of a mask paper. Even though the scheme is theoretically feasible, it is difficult to produce it in an industrialized manner

Chinese patent application No. 2015104391348 announced "a production process for high water retention and tensile facial mask paper". The specific method is to use pulp as a thin material and synthetic long fibers or short fibers as a thin layer of reticular fibers. The two are compounded, and then The facial mask paper is obtained by spunlace and drying. Although the facial mask paper has water retention and stretching ability, because the pulp paper is used as the thin material and the synthetic long fiber or short fiber is used as the network fiber thin layer, the specific surface area is relatively low and the absorption is effective. Component capacity is limited
