Abstract

The invention belongs to the technical field of cosmetics, and discloses graphene oxide-chitosan mask cloth, a mask and a preparation method. The preparation method of the graphene oxide-chitosan mask cloth comprises the following steps of (1), mixing chitosan and polyethylene glycol in an acid solution to obtain a chitosan-polyethylene glycol mixed solution; preparing graphene oxide into a graphene oxide solution by using water; (2), mixing the chitosan-polyethylene glycol mixed solution and the graphene oxide solution, forming a mask, drying, and neutralizing by adopting an alkali solution to obtain a neutralized mask material; and (3), placing the neutralized mask material in water, carrying out heat treatment, and freeze-drying to obtain the graphene oxide-chitosan mask cloth. The mask is mainly prepared by compounding the graphene oxide-chitosan mask cloth and mask liquid. According to the mask cloth, the chitosan and a graphene oxide compound are taken as a base material, the chitosan component is easy to play a role, and a specific environment is not needed; and the mask cloth has antibacterial property, the mask liquid is easy to absorb, and the effect of the mask is better.

Description

technical field [0001] The invention belongs to the technical field of medical beauty and skin care products, and in particular relates to a graphene oxide-chitosan facial mask and a preparation method thereof. Background technique [0002] With the advancement of society and the development of science and technology, people are exposed to sunlight and electronic products every day, which leads to problems such as sagging, aging, and wrinkling of the facial skin, forcing people to spend more energy on facial skin care. The mask industry has grown rapidly in China. develop. The competition for various mask products is fierce. The market is in urgent need of a mask product that is environmentally friendly, mild and non-irritating, and beautifying and beautifying. [0003] The chitosan (chitosan-containing) mask currently on the market is mainly to add the chitosan component to the mask cloth made in advance by drying, so that the mask has a chitosan component, and then soak ...
