Problems solved by technology

However, makeup remover is favored by more and more consumers because of its fast makeup removal and convenient cleaning, but makeup remover is also inconvenient to carry because of the dosage form, and it is more prone to leakage
After the makeup remover is used up, it is necessary to use facial cleanser for secondary cleaning. This cleaning method is cumbersome and brings a lot of inconvenience to consumers. Moreover, makeup remover generally pays attention to efficacy, which is easy to irritate the skin, and the skin is prone to redness, pain, and Peeling, acne and other phenomena

Abstract

The embodiment of the invention discloses a graphene oxide and titanium dioxide composite photocatalyst, a cleaning mask and a preparation method of the cleaning mask, and belongs to the technical field of cosmetics and skin care. The graphene oxide photocatalytic mask comprises a mask layer and a backing layer, wherein the mask layer is arranged on the backing layer, and the mask layer comprises the graphene oxide and titanium dioxide composite photocatalyst, a dispersing agent, film-forming resin and a film-forming cosolvent. The invention further discloses the preparation method of the graphene oxide and titanium dioxide composite photocatalyst and the preparation method of the graphene oxide photocatalytic cleaning mask. According to the graphene oxide and titanium dioxide composite photocatalyst, the cleaning mask and the preparation method of the cleaning mask, the strong adsorption capacity of graphene oxide and the photocatalytic performance of titanium dioxide are utilized, oily secretions and oily cosmetics on the face are quickly adsorbed and decomposed, and therefore the facial skin of the human body is cleaned; and meanwhile, the graphene oxide has high antibacterial performance, is suitable for users with acne on the facial skin, and solves the problem of facial cleaning of oily, makeup and skin sensitive people.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of cosmetics and skin care, in particular to a graphene oxide titanium dioxide composite photocatalyst, a cleansing mask and a preparation method thereof. Background technique [0002] With the improvement of people's living standards and people's constant pursuit of beauty, cosmetics have become people's daily necessities, especially the widespread use of color cosmetic products, making people more and more demanding for makeup remover and facial cleansing products. However, makeup remover is favored by more and more consumers because of its fast makeup removal and convenient cleaning, but makeup remover is also inconvenient to carry because of its dosage form, and it is more prone to leakage. After the makeup remover is used up, it is necessary to use facial cleanser for secondary cleaning. This cleaning method is cumbersome and brings a lot of inconvenience to consumers. Moreover...
