Embodiment 1

[0028] Embodiment 1 natural plant sunscreen

[0029] The natural plant sunscreen of the present embodiment comprises the following components in parts by weight:

[0030] Mulberry xanthin 20 parts

[0031] Isononyl isononanoate 40 parts

[0032] Vitamin E acetate 40 parts.

[0033] The preparation method of above-mentioned natural plant sunscreen is:

[0034] 20 parts by weight of mulberry, 40 parts by weight of isononyl isononanoate and 40 parts by weight of vitamin E acetate are mixed and dissolved at 20° C. to obtain a light yellow liquid, which is a natural plant sunscreen.

[0035] Among them: Mulberrin mainly exists in the bark of mulberry tree and the fruit of Morus alba, and is soluble in organic solvents such as ethanol and ethyl acetate, but insoluble in water. The maximum ultraviolet absorption wavelengths in ethanol are 210nm, 264nm and 315nm. It has good absorption effects in all ultraviolet bands, and has strong reducing properties, anti-inflammatory and anti...

Abstract

The invention discloses a natural plant sun-screening agent as well as a preparation method and application of the natural plant sun-screening agent. The natural plant sun-screening agent comprises mulberrin, isononyl isononanoate and vitamin E acetate, wherein the weight ratio of mulberrin to isononyl isononanoate to vitamin E acetate is 1:1:1-1:3:3. According to the natural plant sun-screening agent, the mulberrin, the isononyl isononanoate and the vitamin E acetate are compounded to form a stable mulberrin-containing sun-screening agent. The natural plant sun-screening agent and the traditional organic sun-screening agent and an inorganic sun-screening agent have a synergistic interaction function, and therefore, a sun care preparation added with the sun-screening agent is mild in skin and high in safety, and is greatly improved in SPF (Sun Protection Factor) value. The preparation method of the sun-screening agent is simple in process and low in production cost.

Description

technical field [0001] The invention relates to the field of cosmetics, in particular to a natural plant sunscreen and its preparation method and application. Background technique [0002] Ultraviolet rays in sunlight can be divided into UVA (320nm-400nm), UVB (290nm-320nm) and UVC (200nm-290nm) according to wavelength. as table 1 and figure 1 As shown, in general, short-wave ultraviolet UVC rays are basically absorbed by the ozone layer in the atmosphere, and the remaining small amount reaches the ground, which will not cause harm to the human body; medium-wave ultraviolet UVB will penetrate the epidermis and stratum corneum of the skin and cause burns , indirect pigmentation and the main root of skin cancer. Burns mainly show erythema on the skin. In severe cases, symptoms of edema, blisters, peeling, fever and nausea may occur. The damage of long-wave ultraviolet UVA to the human body has gradually attracted people's attention. It can wear Penetrating the dermis, even t...
