preparation example Construction

[0034] The preparation process of self-made polyurethane is as follows: take 6-8 parts of epoxy resin and 6-8 parts of nanocellulose in a mixer, the temperature is room temperature when stirring, the speed is 250-350r / min, and the mixing time is 10 minutes at constant temperature. After mixing, add 6 to 8 parts of glucose aqueous solution into the mixer and continue stirring. During stirring, the temperature is room temperature, the rotation speed is 250 to 350 r / min, and the mixing time is 10 minutes at constant temperature to obtain self-made polyurethane.

[0035] The preparation process of self-made grape seed anthocyanins is as follows: take 6-8 parts of grape seed anthocyanins and put them in a blender, add 0.5-0.8 parts of sodium hydroxide solution, stir at room temperature, and rotate at 250-350r / min. Stirring and mixing at constant temperature for 15 minutes to obtain self-made grape seed anthocyanins.

Abstract

The invention discloses an environment-friendly physical sunscreen cream and a preparation method thereof. The environment-friendly physical sunscreen cream is prepared from the following raw materials: zinc oxide, titanium dioxide, an emulsifier, glycerol, urethane, absolute ethyl alcohol, butanediol, dioctyl malate, polysiloxane, hydroxybenzoate, home-made polyurethane, epoxy resin, nano cellulose, glucose, polyurethane and home-made grape seed proanthocyanidin. The invention further comprises the environment-friendly physical sunscreen cream and a preparation method thereof, certain improvements are made on the basis of traditional physical sunscreen cream, and the effect of environmental protection is achieved while the sunscreen effect is not affected. According to the preparation method, modified home-made polyurethane and home-made grape seed proanthocyanidin are added into traditional physical sunscreen cream, so that diffusion of effective component titanium dioxide in the physical sunscreen cream in the air can be effectively reduced, the sunscreen effect is indirectly reinforced to a certain extent, the effects of retarding senescence, whitening skin and enhancing skin immunity are improved, and dual effects of effectively protecting the environment and enhancing sunscreen are achieved.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to an environment-friendly physical sunscreen and a preparation method thereof. Background technique [0002] As the ozone layer is increasingly damaged, the damage of ultraviolet rays to human skin has gradually increased. Although the ultraviolet rays of the sun can kill or inhibit the bacteria on the skin surface, enhance the body's resistance, and promote important functions such as metabolism. But ultraviolet rays still have damage to human skin and hair, such as causing redness, burning pain and other symptoms, inhibiting protein synthesis, reducing skin elasticity, producing wrinkles, causing skin aging, and even skin cancer. Solar ultraviolet radiation is the main cause of most skin diseases including skin cancer. The incidence of non-melanoma skin cancer induced by ultraviolet rays is gradually increasing in the world. Therefore, it is urgent to resist the harm caused by...
