Problems solved by technology

[0007] According to the above, among the natural Chinese medicine plants used for UV protection in the existing scheme, the color of the Chinese medicine itself is not conducive to direct application, and the decolorization treatment has an impact on its UV absorption function, which limits the utilization of important UV absorbers in sunscreen cosmetics. The present invention proposes an inorganic-natural plant synergistic sunscreen and skin care cream and its preparation method, which can effectively solve the above-mentioned technical problems

Abstract

The invention relates to the field of a skin care product, and discloses inorganic natural plant cooperated sunscreen skin care cream and a preparation method thereof. The method comprises the following preparation processes of (1) compounding natural plant extracts with anti-UV functions; (2) performing dispersion with water, emulsifying agents and glyceryl stearate; then, performing spray dryingto obtain compound extract microspheres; (3) adding a zinc acetate solution; then, dripping sodium hypochlorite and urea; performing heating reaction; (4) performing washing drying; then, obtaining sunscreen additives; (5) performing uniform mixing with Carbomer, chitosan liquid, preservatives, glycerinum, hydrolyzed collagen and deionized water to obtain the inorganic natural plant cooperated sunscreen skin care cream. The sunscreen skin care cream prepared by the method has the advantages that through UV adsorption capability of inorganic blocking ultraviolet and plant ultraviolet absorbents, the anti-UV capability of the sunscreen cream is improved; in addition, the ingredients are natural; the skin irritation is avoided; the color is not influenced by the color of plant extracts; after the use, the anti-UV capability is high.

Description

technical field [0001] The invention relates to the field of skin care products, and discloses an inorganic-natural plant synergistic sunscreen and skin care cream and a preparation method thereof. Background technique [0002] In recent years, the amount of ultraviolet radiation has been increasing along with the destruction of the ozone layer, and the impact on human beings has been recognized worldwide. The amount of ultraviolet radiation continues to increase with the destruction of the ozone layer. If there is no protective measure, the skin will experience redness, swelling, burning pain, blisters, decreased elasticity, wrinkles, and aging after prolonged exposure to sunlight without any protective measures. The immune system is suppressed, which can even lead to skin cancer. Therefore, the choice of sunscreen and sunscreen skin care products will become the focus of researchers and consumers, both today and in the future. [0003] At present, ultraviolet absorbing (...
