Embodiment 1

[0027] A kind of preparation method of plant composite sunscreen

[0028] Ashitaba roots were dried and crushed, added with 70% volume concentration of ethanol solution, ultrasonically assisted for 1 h, filtered and concentrated under reduced pressure, then absorbed by AB-8 macroporous resin and eluted with organic solvents, and concentrated under reduced pressure to obtain Ashitaba Extract.

[0029] Dried and crushed Rosa roxburghii fruit, added 80% volume concentration of ethanol solution, ultrasonically assisted extraction for 1 h, filtered and concentrated under reduced pressure, then absorbed by AB-8 macroporous resin and eluted with organic solvent, and concentrated under reduced pressure to obtain Rosa roxburghii Extract.

[0030] Dry and crush the mangosteen peel, add 80% volume concentration of ethanol solution, ultrasonically treat for 30 min, extract overnight, filter and concentrate under reduced pressure, redissolve the extract with water, extract with ethyl acet...

Embodiment 2

[0033] UV absorption test of plant compound sunscreen: prepare sunscreen base, add the prepared plant compound sunscreen into the sunscreen base at a ratio of 10%, and measure the SPF value and PA value of the plant compound sunscreen by SPF-290S critical wavelength.

[0034] The specific formula of sunscreen is as follows (w / %): stearic acid 6.0, glycerin 6.0, cetyl alcohol 4.0, octyl palmitate 3.0, glyceryl stearate 2.0, lanolin 2.0, polyethylene glycol (40) stearic acid Ester 1.0, Dimethicone 1.0, Lauramidopropyl Dimethylamine 2.0, Olive Oil 2.0, Acrylic Copolymer 0.5, Triethanolamine 1.5, Plant Complex Sunscreen 10, Deionized Water 59.

[0035] With 3M adhesive tape as a support, the sample is pressed at 1mg / cm 2 Spread it evenly on the tape, and use the sunscreen matrix without plant compound sunscreen as a blank control to measure the SPF value and PA critical wavelength of the plant compound sunscreen. The experimental results are shown in Table 1.

[0036] Table 1 UV...

Embodiment 3

[0040] Antioxidant ability test of plant compound sunscreen:

[0041] 1), FRAP method - total antioxidant capacity test

[0042] Principle: The principle of FRAP method to measure total antioxidant capacity is that antioxidants can reduce Ferric-tripyridyltrizaine (Fe3+ -TPTZ) produces blue Fe 2+ -TPTZ, followed by absorbance measurement of blue Fe 2+ -TPTZ to obtain the total antioxidant capacity of the sample.

[0043] Test method: Dissolve the plant compound sunscreen in DMSO to make a 1mM solution, react with FRAP reagent under acidic conditions for 30 minutes, then measure its absorbance at 597 nm, and use 1mM Vc as a positive control. The experimental results are shown in Table 2.

[0044] Table 2 FRAP method—total antioxidant capacity test

[0045] sample FRAP value 1 mM Vc 1.59 4:2:4 6.72 3:3:4 6.56

[0046] As can be seen from Table 2, the plant composite sunscreen prepared by the present invention has very good total antioxidant cap...

Abstract

The invention relates to the technical field of cosmetics, in particular to a plant composite sun-screening agent and preparation and application thereof. The plant composite sun-screening agent is prepared by compounding angelica keiskei extract, roxburgh rose extact and garcinia mangostana L. pericarp extract. The plant composite sun-screening agent is prepared by compounding the angelica keiskei extract, the roxburgh rose extact and the garcinia mangostana L. pericarp extract according to a certain ratio, long-wave ultraviolet and medium-wave ultraviolet can be well absorbed, and a good sun-screening effect is achieved. In addition, the plant composite sun-screening agent further has very good anti-oxidation capacity, free radicals generated when the ultraviolet irradiates skin of the human body can be removed, a certain tyrosinase activity inhibition ratio is achieved, a certain skin whitening effect is achieved, and very good cosmetic application potential is achieved.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to a plant composite sunscreen and its preparation and application. Background technique [0002] Ultraviolet light is a general term for radiation with wavelengths from 100-400nm in the electromagnetic spectrum. Ultraviolet rays can be divided into three types according to wavelength: UVA (long-wave ultraviolet 320-400nm), UVB (medium-wave ultraviolet 280-320nm), and UVC (short-wave ultraviolet 200-280nm). Due to the barrier of the ozone layer, UVC cannot reach the surface, but UVA and UVB can reach the surface through the atmosphere, causing damage to human skin. UVB can reach the dermis and cause sunburn, erythema, blisters and other damage to the skin; UBA can penetrate the dermis, damage cell DNA, damage collagen, accelerate skin aging, and even cause skin cancer. [0003] With the deepening of people's understanding of ultraviolet rays, the necessity of outdoor sun protect...
