[0007] Purpose of the present invention: in order to absorb ultraviolet rays (UVB) of 290nm-320nm that can burn the skin and ultraviolet rays (UVA) that make the skin tanned with a wavelength of 320nm-400nm, the present invention has produced a compound plant flavonoid compound containing Magnolias A natural skin care sunscreen made of compound animal and vegetable oils such as extracts and raccoon oil. This sunscreen has a strong absorption effect on ultraviolet rays in the range of 200nm-400nm. It uses plants extracted from various plants such as Magnolias to absorb ultraviolet rays and has antioxidant effects. Compound flavonoids, compounded with raccoon oil, badger oil and other animal and vegetable oils, can promote the re-epithelialization of the wound surface and the differentiation activity of each layer of the epidermis, promote muscle growth, skin care, relieve pain, and keep the wound moist. The preparation of natural sunscreen overcomes the relatively narrow ultraviolet absorption spectrum in the current market and the promotion of re-epithelialization of the wound surface and the differentiation activity of each layer of the epidermis, as well as skin care and pain relief, keeping the wound moist and heat preservation, antifreeze, and anti-cracking Difficulties that cannot be achieved at the same time

Embodiment 1

[0052] Preparation of plant compound flavonoids extract

[0053] Weigh 0.50g Magnolia flavonoids extract, dissolve in 20mL ethanol to obtain a 25g / L solution, take 0.1mL, 0.2mL, 0.3mL, 0.4mL, 0.5mL respectively, and dilute to 50mL with ethanol to obtain Gradient solution, respectively measure the absorbance value, the results are shown in Table 1. By plotting the solution concentration and the average value of absorbance, the linear regression equation is: y=2.1185x+0.3861, R 2 =0.9955, where x is the concentration of the solution, and y is the absorbance value. Substituting x=0.5 into the equation gives y=0.05375, and the approximate value is 0.050.

[0054] Weigh 0.50g Sophora japonica flavonoids extract, dissolve in 20mL ethanol to obtain a 25g / L solution, take 0.1mL, 0.2mL, 0.3mL, 0.4mL, 0.5mL respectively, and dilute to 250mL with ethanol to obtain Gradient solutions, respectively measured absorbance values, the results are shown in Table 2. The linear regression equat...

[0065] Preparation of animal and vegetable compound oils:

[0066] First, measure the fatty acid composition of various oils, take 50g of raccoon oil and badger oil respectively, and calculate the similarity k before adjustment according to the above formula 1 according to the fatty acid composition 1 =3.1, after a lot of calculations, finally determined raccoon oil 50g, badger oil 50g, butter 28g, mink oil 15g, pumpkin seed oil 15g, sunflower oil 12g, chicken oil 10g, lard 1g, sheep oil 0.5g, horse oil Oil 0.7g, rabbit oil 0.4g, duck oil 0.5g, goose oil 0.3g, hickory oil 0.5g, red pine seed oil 0.5g, elderberry oil 0.5g, pine nut oil 0.5g, apple seed oil 0.5g, leek Seed oil 0.3g, evening primrose oil 0.5g, perilla oil 0.5g, olive oil 1.2g, peanut oil 0.5g, soybean oil 0.5g. And calculate the adjusted similarity k 2 =0.83, set k 1 with k 1 Substituting into formula 2, the oil composite index M=2.73, which is greater than 2.0, shows that the adjusted oil and raccoon oil hav...

Abstract

The invention relates to a magnolia sieboldii compound natural sunscreen cream and a preparation method thereof. By using flavonoid compounds extracted from magnolia sieboldii, pagodatree flower bud and radix scutellariae as main raw materials, the magnolia sieboldii compound natural sunscreen cream has an obvious broad-spectrum strong ultraviolet absorption effect. By compounding flavonoid compound extracting solution of plants such as magnolia sieboldii with mink oil close to body fat and badger fat with the effects of promoting tissue regeneration, protecting skins and relieving pains and keeping wound wet, a novel natural sunscreen cream containing a plant flavonoid capable of absorbing ultraviolet, and animal and plant compound fat composed of heat-preserving, freeze-proofing and split-preventing fatty acids is obtained.

Description

technical field [0001] The invention relates to a magnolia composite natural sunscreen and a preparation method thereof, in particular to using magnolia essential oil, plant flavonoid extracts such as magnolia and compound animal and vegetable oils as raw materials to prepare a composite natural sunscreen, and the invention belongs to the field of cosmetics. Background technique [0002] Relevant literature records: He Xili et al reported in Northwest Pharmaceutical Journal, 13 (6), 157-258, 1998 that long-term exposure to sunlight would cause burning pain, redness, peeling and aging of the skin, and photosensitivity may present dermatitis, redness rash to skin cancer. This is damage caused by ultraviolet rays in sunlight. Ultraviolet rays (UVB) with a wavelength of 290nm-320nm can burn the skin, and ultraviolet rays (UVA) with a wavelength of 320nm-400nm can make the skin tan. Commercially available sunscreens are mostly synthetic products, and some products still have un...
