Hydrogel repair mask and preparation method thereof

Abstract

The invention discloses hydrogel repair mask, belonging to the technical field of skin care products. The hydrogel repair mask is transparent gel mask; the gel mask is prepared from the following components in parts by weight: 0.5-2 parts of carrageenan, 0.5-2 parts of konjac gum, 0.3-0.8 part of chitosan, 1-2 parts of cross-linking accelerator, 10-15 parts of solubilizing and moisturizing agent and 60-80 parts of pure water, wherein the chitosan is selected from one or two of carboxymethyl chitosan, hydroxypropyl chitosan and chitosan quaternary ammonium salt; the cross-linking accelerator isselected from one or two of potassium chloride, calcium chloride and potassium dihydrogen phosphate; the solubilizing and moisturizing agent is selected from one or two of glycerol, propylene glycoland butylene glycol. The invention also discloses a preparation method of the hydrogel repair mask. The hydrogel repair mask has good ductility, toughness and adhesion property, and can be used for wound repair.

Description

technical field [0001] The invention belongs to the technical field of skin care products, and in particular relates to a hydrogel repair mask and a preparation method thereof. Background technique [0002] As a facial application product, facial mask has a higher content of functional ingredients than daily skin care products, and can solve skin problems to a certain extent. Existing facial mask is mainly divided into mud paste facial mask and application type facial mask, and mud paste facial mask is that the paste is directly applied to the face, and after a period of time, it is washed off or torn off. Most of this mud cream facial mask is sealed. Poor performance, causing the mask to lose water quickly, so the application mask is more widely used. The traditional application mask uses tissue paper or non-woven fabric as the carrier substrate, and the carrier substrate acts as a medium to absorb functional liquids, and can be fixed on a specific position on the face to ...

AI Technical Summary

Problems solved by technology

The chemical cross-linking method has a fast preparation speed, but there are potential hazards in most of the ingredients in the prescription, such as using the chemical cross-linking agent glutaraldehyde; the radiation cross-linking method will cause the color of the hydrogel to become yellow and hard; the prior art ( CN106420368A) discloses a kind of preparation method of sticking type hydrogel base mask, obtains by repeatedly freezing and thawing the PVA aqueous solution that is added with corresponding skin care composition, although the hydrogel prepared by freezing-thawing cross-linking method has high strength, does not fall off. However, the resulting hydrogel has the disadvantages of rough skin contact and low transparency
