Problems solved by technology

The film cloth of the application mask is mainly divided into non-water-soluble non-woven fabrics and water-soluble polymer films. The preparation methods mainly include sizing method, spunlace method, physical or chemical bonding method, but these methods are in some aspects There are more or less deficiencies in all: for example, the preparation method of the sizing method is complicated to operate and is not suitable for mass production in factories; although the spunlace method can produce soft and breathable non-woven fabrics, the operating equipment is cumbersome and the operating cost is high. ; Both physical and chemical bonding methods need to be bonded for reinforcement. In addition, the membrane cloth prepared by this method has thick fibers and cannot fully fit the face.
In the preparation process of the invention, various solutions need to be prepared, and the PVA aqueous solution, the sodium alginate aqueous solution and the spinning mixed solution need to be allowed to stand and then the pre-treatment of the residue filtration is performed, and the operation process is cumbersome; and the mask only contains water-soluble beauty ingredients , not involved in water-soluble oil-soluble beauty ingredients with powerful skin care functions

Embodiment 1

[0041] A preparation method of a self-supporting solid multi-component facial mask, the steps are as follows:

[0042] (1) Add polyvinylpyrrolidone (PVP) (weight-average molecular weight is 780000) in absolute ethanol, stir at room temperature, after PVP dissolves completely, make concentration be 0.09g / mL (quality of polyvinylpyrrolidone / absolute ethanol volume) of the PVP solution; then in the PVP solution, add resveratrol (the addition of resveratrol is 2% of the PVP quality), continue to stir until dissolved, as the nuclear layer spinning solution;

[0043] (2) Add polyvinyl alcohol (PVA) (number average molecular weight: 63800) into deionized water, then raise the temperature to 70°C, condense and reflux under stirring, after the PVA is completely dissolved, cool to room temperature, and make the concentration 0.08g / mL (the quality of polyvinyl alcohol / the volume of deionized water) PVA solution; then add nicotinamide (the addition of nicotinamide is 2% of the PVA quality...

Abstract

The invention provides a preparation method of a self-support solid-state multi-component mask. The preparation method is characterized in that oil-soluble skincare effective substances are dissolvedin polyvinyl pyrrolidone to serve as the core-layer spinning solution, water-soluble skincare effective substances are dissolved in polyvinyl alcohol to serve as the shell-layer spinning solution, a coaxial electrostatic spinning method is used to load the water-soluble skincare effective substances to the fiber shell layer and load the oil-soluble skincare effective substances to the fiber core layer, and accordingly two or more skincare effective substances different in solubility are loaded into a fiber membrane at the same time, and the mask can have better or various effects. The preparation method is simple in preparation process and easy in component and fiber structure control, and the self-support mask prepared by the method is good in mechanical performance and breathability.

Description

technical field [0001] The invention relates to a preparation method of a self-supporting solid multi-component facial mask, which belongs to the technical field of material science and cosmetics. Background technique [0002] Mask is a kind of skin care product. Mask has various functions, such as cleansing the skin, anti-wrinkle and anti-spot, anti-oxidant and whitening, hydrating and moisturizing, balancing water and oil balance, anti-inflammatory and anti-acne, etc. The types of facial masks mainly include tear-off type, smear type (paste and cream), and application type. The application mask has become the most widely used mask type because of its relative ease of use. The application-type mask is a membrane cloth made of polymer as a carrier. Various skin care nutrients and essences are stored in the membrane cloth in liquid form. The user can directly apply the membrane cloth loaded with liquid functional substances on the face. The substance enters the skin to act....
