Abstract

The present invention discloses a high-strength anti-ultraviolet-ray silk fibroin sunscreen cream, which is characterized in that the raw materials comprise, by weight, 10-15 parts of a silk fibroin membrane with a concentration of 12 wt%, 6-8 parts of glycerin, 4-6 parts of phosphate, 1-1.5 parts of a whitening agent, 1-1.2 parts of beeswax, 0.6-0.8 part of vitamin E, 0.4-0.6 part of sodium carboxymethyl cellulose, 3-5 parts of a natural extract, 0.5-0.8 part of glyceryl monostearate, 1-2 parts of citric acid, and 20-25 parts of deionized water. According to the present invention, the silk fibroin membrane can be absorbed by human body tissue, ultraviolet-ray resistance is excellent, the solution can be recycled, and the green environmental protection advantage is provided; and the sunscreen cream has characteristics of no skin toxicity, no skin stimulation and no allergy, and further has effects of moisturizing, repairing, skin moisturizing, and whitening.

Description

technical field [0001] The invention belongs to the technical field of skin care products, and in particular relates to a high-strength anti-ultraviolet silk fibroin sunscreen. Background technique [0002] Sunscreen refers to cosmetics that add sunscreen agents that can block or absorb ultraviolet rays to prevent skin from being tanned and sunburned. Specifically, sunscreens that block ultraviolet rays generally refer to physical sunscreen ingredients. Its principle is like wearing an umbrella and hat, which can reflect the ultraviolet rays that irradiate the human body. The main ingredients include zinc oxide, titanium dioxide, and physical sunscreen powder. UV-absorbing sunscreens generally refer to chemical sunscreen ingredients, which can absorb the energy of ultraviolet rays and undergo chemical reactions. Sunscreens are getting more and more attention. Consumers' awareness of sunscreens has reached a new level. Not only do they require sunscreens to have a significan...
