Abstract

The invention discloses a fibroin sunscreen cream and a preparation method thereof, and relates to the technical field of daily chemicals. The fibroin sunscreen cream comprises the following raw materials in parts by weight: 10-20 parts of an oil phase, 60-80 parts of a water phase and 3-5 parts of an emulsifier, wherein the water phase is prepared from the following raw materials in parts by weight: 100-200 parts of water, 10-20 parts of glycerol, 8-10 parts of graphene oxide, 3-5 parts of dopamine and 8-10 parts of fibroin; chemical bonds are at least partially formed between dopamine and fibroin; at least part of a dopamine molecular chain is embedded into the main chain of a fibroin molecular chain; nano inorganic powder is embedded into an inter-layer structure of graphene oxide; andthe nano inorganic powder is nano zinc oxide and/or nano titanium dioxide. The product obtained by the invention has a good sunscreen effect and an excellent moisturizing effect at the same time.

Description

technical field [0001] The invention relates to the technical field of daily chemicals, in particular to a silk protein sunscreen and a preparation method thereof. Background technique [0002] The effects of silk protein include but are not limited to beautifying and nourishing the skin, moisturizing the skin, moisturizing and sun protection, etc. It is one of the functional additives in daily chemicals that are generally applicable at present. Adding silk protein to daily chemicals, replacing conventional additives, not only has higher safety, prevents skin from allergic dermatitis, but also can give full play to the natural efficacy of silk protein. [0003] Natural silk replaces broad-spectrum sunscreen agents in traditional sunscreen products, such as nano-titanium dioxide / zinc oxide, etc., and has become one of the trends in safe and effective sunscreen products; however, although sunscreen products inherit the excellent sunscreen performance of silk protein, their moi...
