Problems solved by technology

However, this formula has the following disadvantages: 1. its crosslinking agent is a single physical crosslinking agent, aluminum glycinate or a composite aluminum salt, and the prepared mask matrix has poor elasticity, water retention and strength; 2. the composition of the antibacterial agent is as follows: Benzoic acid has potential safety hazards, and human skin may have an allergic reaction to it; 3. The solution obtained from the formula needs to be adjusted with an alkaline PH regulator, which is not easy to control on the one hand, and will cause residues of harmful ingredients on the other hand
However, due to the high price of isopropylacrylamide and polyurethane, the preparation method is complicated, and it is difficult to produce on a large scale
In addition, since the non-woven fabric is used as a support, the mask cannot be completely attached to the face, leaving some gaps

Abstract

The invention relates to a highly-elastic non-supported environmentally-friendly gel mask and a preparation method thereof. The gel mask is formed by dissolving an olefin monomer M1, a biological polymer M2, a chemical cross-linking agent M3, a physical cross-linking agent M4, plant extract essential oil, whitening components and anti-ageing active components in water, and polymerizing. The preparation method comprises the following steps: 1, preparing aqueous solutions of the M1, M2, M3 and M4; 2, preparing an essence liquid; 3, mixing to prepare a prepolymer liquid; 4, preparing the gel mask; and 5, packaging the gel mask. The gel mask prepared through the method has the advantages of moderate viscosity, good elasticity, good ductility and toughness, no need of the application of a non-woven fabric to improve the mechanic strength, carrying convenience, adjustable thickness, and repeatable use, and allows the viscoelasticity, the skin endophilicity and the moisture retention performance of the mask to be adjusted by adjusting the monomer concentration, the feeding ratio, the whitening and anti-ageing active components, the reaction temperature, the water content and the feeding sequence. The gel mask can be used in the fields of skin care, moisture retention, beauty treatment, anti-ageing and the like.

Description

technical field [0001] The invention relates to the fields of polymer materials, cosmetics and biomedicine, in particular to a high-elasticity unsupported environment-friendly gel mask and a preparation method thereof. Background technique [0002] Mask is a category of skin care products. Its most basic and important purpose is to make up for the insufficient cleaning work of makeup remover and face wash, and to achieve other maintenance functions on this basis, such as moisturizing, whitening, anti-aging and so on. The principle of the mask is to use the short time covered on the face to temporarily isolate the outside air and pollution, increase the temperature of the skin, expand the pores of the skin, promote the secretion and metabolism of sweat glands, increase the oxygen content of the skin, and help the skin to eliminate the skin. The products of cell metabolism and accumulated oily substances, the moisture in the mask penetrates into the stratum corneum of the epid...
