Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a plant-based light-repairing sunscreen and its preparation method in view of the problems that the particle size of titanium dioxide in the sunscreen is too small to easily agglomerate, which is not conducive to dispersion, and is also easy to block the pores of the skin, which is not conducive to ventilation.

example 1

[0030] Put Scutellaria baicalensis into the ultrafine pulverizer after drying naturally, and pass through a 300-mesh sieve to obtain Scutellaria baicalensis powder; dry Chrysanthemum chrysanthemum naturally, put it into an ultrafine pulverizer and pulverize it, pass through a 300-mesh sieve to obtain the Scutellaria chinensis powder. Chrysanthemum chrysanthemum powder, dry the Antarctic ice algae naturally, put it into a superfine pulverizer, and pass through a 300-mesh sieve to obtain the Antarctic ice algae powder. Take 100g of Scutellaria chinensis powder, 100g of chrysanthemum chrysanthemum powder, and 50g of Antarctic ice algae powder. Add 1 L of ethanol solution with a mass fraction of 70%, heat and reflux at 60°C for 2 hours to obtain a crude extract, distill the crude extract under reduced pressure until it is free of ethanol, and absorb it through a macroporous resin column until it is colorless, and then use The ethanol solution with a mass fraction of 50% was eluted ...

[0032]Put Scutellaria baicalensis into the ultrafine pulverizer after drying naturally, and pass through a 300-mesh sieve to obtain Scutellaria baicalensis powder; dry Chrysanthemum chrysanthemum naturally, put it into an ultrafine pulverizer and pulverize it, pass through a 300-mesh sieve to obtain the Scutellaria chinensis powder. Chrysanthemum chrysanthemum powder, put the Antarctic ice algae into a superfine pulverizer after naturally drying, and pass through a 300-mesh sieve to obtain the Antarctic ice algae powder. Take 150g of Scutellaria chinensis powder, 150g of chrysanthemum chrysanthemum powder, and 75g of Antarctic ice algae powder. Add 1 L of ethanol solution with a mass fraction of 70%, heat and reflux at 70°C for 2 hours to obtain a crude extract, distill and concentrate the crude extract under reduced pressure to no ethanol, and absorb it through a macroporous resin column until it is colorless, and then use The ethanol solution with a mass fraction of 50% was e...

Abstract

The invention relates to a plant-based light repairing sunscreen cream and a preparation method thereof and belongs to the technical field of cosmetics. According to the plant-based light repairing sunscreen cream, rabbit hair keratin is used for coating titanium dioxide; the characteristics of high skin friendliness, no toxicity and adsorbability of the rabbit hair keratin are used; the sunscreenscram can improve the effect of scattering ultraviolet light, is easily dispersed and absorbed by pores of the skin, avoids the problem that the pores are blocked by large particle size of the particles, is combined with plant effective components, is capable of inhibiting tyrosinase activity so as to avoid generation of melanin, slowing down the skin allergy reaction caused by ultraviolet radiation, actively repairing pyrimidine dimmers generated by ultraviolet radiation in the skin cells so as to protect the skin, preventing and treating malignant diseases such as melanoma and skin cancer and the like caused by ultraviolet injury and repairing the DNA structures of the injured cells. The plant-based light repairing sunscreen cream is mild, is free of irritation and high in stability andcan achieve the beautifying effects of resisting senescence and whitening.

Description

technical field [0001] The invention relates to a plant-based light repairing sunscreen and a preparation method thereof, belonging to the technical field of cosmetics. Background technique [0002] Sunscreen protects the skin by reflecting and scattering ultraviolet rays. Ultraviolet rays have negative effects on cell DNA, membranes and the immune system. Sunscreens can protect cells and the immune system, and titanium dioxide is one of the main components of sunscreens. The strong anti-ultraviolet ability of titanium dioxide is due to its high refraction and high photoactivity. Ultraviolet rays in both the medium-wave and long-wave regions are effective. The sunscreen mechanism is simple covering, which is a general physical sunscreen, and the sunscreen ability is weak; The reflection and scattering are not obvious, but the absorption of ultraviolet rays in the medium-wave region is significantly enhanced. The sunscreen mechanism is to absorb ultraviolet rays, mainly abs...
