Description

Sunscreen agent and application thereof in cosmetics
Technical Field
The invention belongs to the technical field of cosmetics, and particularly relates to a sun-screening agent and application thereof in cosmetics.
Background
With the pursuit of beauty, cosmetics are increasingly widely applied. In order to prevent the skin from being sunburned and sunburned by ultraviolet rays, a sunscreen agent is used in many cosmetics. Sunscreens are generally classified into physical screening sunscreens and chemical absorbing sunscreens: the physical screening sun-proof agent mainly reflects, scatters and blocks ultraviolet rays so as to achieve the sun-proof effect; the chemical sun-screening agent can perform photochemical reaction with ultraviolet rays, so that the chemical sun-screening agent is converted into a lower energy form, and the direct damage of the ultraviolet rays to the skin is weakened.
Compared with a physical screening sun-screening agent and a chemical absorption sun-screening agent, flowers or natural plants have the advantages of being safer, milder, more lasting and efficient, natural sun-screening ingredients of the plants or the flowers become a great trend of research and development of the existing sun-screening cosmetics, and the flowers or the natural plants have unique advantages in the aspect of avoiding and reducing the toxic and side effects of the cosmetics.
CN 112006955B discloses a flower traditional Chinese medicine compound sunscreen agent and an application thereof in cosmetics, wherein the flower traditional Chinese medicine compound sunscreen agent comprises the following raw materials: sweet osmanthus flower, coreopsis tinctoria flower and sunflower flower, and application of the flower traditional Chinese medicine compound sun-screening agent in cosmetics. The flower traditional Chinese medicine compound sunscreen agent selects sweet osmanthus, kunlun snow chrysanthemum and sunflower as main raw materials, has a good sunscreen effect, has the advantages of safety and no irritation, and can be used for a long time. However, the flower traditional Chinese medicine compound sun-screening agent is completely made of flowers, mainly absorbs ultraviolet rays to screen the sun, and does not have the functions of shielding and reflecting the ultraviolet rays.

Figure 331539DEST_PATH_IMAGE001
The preparation method of the sunscreen cream comprises the following steps: pre-dispersing sodium hyaluronate, ammonium acryloyldimethyl taurate/VP copolymer and xanthan gum by using glycerol and 1, 3-butanediol, sequentially adding deionized water, sorbitol, beta-glucan and disodium ethylene diamine tetraacetate, uniformly dispersing, heating to 85 ℃, and preserving heat for 10min for later use, wherein the phase A is marked; sequentially adding the raw materials of phase B into another beaker, uniformly dispersing, heating to 85 ℃, and keeping the temperature for 10min for later use; quickly adding phase B into phase A, homogenizing, maintaining the temperature at 85 deg.C for 3min, stirring, maintaining the temperature for 30min, cooling to 45 deg.C, adding phase C and phase D, and stirring. Wherein phase D is a sunscreen of the present invention and the control group does not contain phase D.
Measuring the ultraviolet absorbance A value of the sunscreen cream in UVB region (280-320 nm) by using an ultraviolet spectrophotometer as an ultraviolet light source according to the sunscreen effect evaluation method of sunscreen cosmetic standard QB/T2410-1998. The method specifically comprises the following steps:
cutting 3M medical air permeable adhesive tape into strips of 4cm × 1cm, accurately weighing 4mg of traditional Chinese medicine sunscreen cream sample on the adhesive tape, uniformly coating, standing for 30min, and attaching to one side of the transparent surface of a cuvette for data determination. The sunscreen effect of the sunscreen cream in UVB ultraviolet band is judged by the absorbance and referring to a comprehensive sunscreen effect table as shown in Table 2.
