DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of using an alcohol extract of Fengxiang flower for protecting the skin and cutting off harmful ultraviolet rays as a skin protection agent.

[0002]

BACKGROUND OF THE INVENTION It has been shown that "moisture" is closely related to the retention of youthful skin. Moisturizing the skin is one of the important functions for cosmetics. In the stratum corneum of human skin, there is a hydrophilic absorbent substance called NMF (Naturally moisturizing factor), which plays an important role in moisturizing the skin. However, most of the cosmetics used today are chemically synthesized products, and are not necessarily desirable substances for the skin.Therefore, when the cosmetics were applied, the skin became rough, and a vicious cycle of using cosmetics to make up for this was a vicious cycle. . In addition, even cosmetics using natural products are easily oxidized, so that the use of a chemically synthesized antioxidant has the disadvantage of roughening the skin. It is a vegetable extract that is gentle on the skin and can be used as a skin protection agent. It is hardly oxidized and there is no substance that cuts off ultraviolet rays.

[0003]

If there is a substance which is hardly oxidized by a plant-based extract substance, helps to moisturize the skin, has an affinity for the skin, and cuts harmful ultraviolet rays,
It is an ideal skin protection agent.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below. First, the Fengxian flower alcohol extract used in the present invention will be described. Fengxian flower is an annual plant (including closely related and subspecies) that belongs to the genus Trichoderma and the swelling family. Can also be used.
After harvesting the whole plant from summer to autumn and using it as it is or drying it in the sun, the fruits are collected before maturity and dried in the sun, and only the seeds are collected after drying. The ingredients are naphthoquinones,
It is known that flowers contain anthocyanins and thianidines, foliage contains kaempferol, quercetin and the like, and seeds contain parinalysin fatty acids, fatty oils, and ergosterol. The Fengxian flower may be collected during the flowering stage and shaded for 2 to 5 days. The cut whole plant and petals are immersed in an alcohol-containing aqueous solution having an alcohol content of 10 degrees or more. The alcohol used in the present invention is preferably an aqueous alcohol-containing aqueous solution of 10 degrees or more in order to extract the active ingredient of the whole flower of Hosenbana, but other distilled spirits, brewed liquors, mixed liquors, and synthetic liquors. Alternatively, white liquor (shochu) or the like may be used. In addition, a methyl alcohol-containing aqueous solution or an isopropyl alcohol-containing aqueous solution having a temperature of 10 degrees or more can be used depending on the application. The compounding ratio is preferably 2 to 5 parts by weight with respect to 10 parts by weight of white liquor. Soak for 2 weeks to 6 months, preferably for 6 months to 1 month. After the immersion, the residue is separated by means such as a dry mesh method to obtain an alcohol extract of Fengxian flower.
As mentioned earlier, this impatiens alcohol extract naphthoquinone derivative (vitamin K-like effect), (precursor material of naphthoquinone) kaempferol, flavonoids, and the main component and ergosterol (precursor substances of vitamin D ₂₎ Solution. After that, the present inventor continued the research and performed analysis. As a result, the alcohol extract of Fengxiang flower contained NMF (n
atural moisturizing facto
r = natural moisturizing factor), the amino acids that make up 40% of the composition: serine, glycine, alanine, valine, leucine, isoleucine, methionine, threonine, phenylalanine, lysine, tryptophan, tyrosine, proline, histidine, arginine, glutamine and Since it contains the same amino acids and even citric acids, it is the most suitable cosmetic material for moisturizing the skin. In addition, 234 nm, 248 nm, 261 nm, 2
There are strong maximum absorption spectra around 70 nm and 325 nm. Therefore, 290-320 nm causing erythema of the skin
Since it absorbs ultraviolet rays (Dornow rays) and absorbs a wavelength around 260 nm which causes skin cancer, it is a skin protective agent that cuts off harmful ultraviolet rays, and it can be used as a suntan cosmetic. In addition, they have found the following effects. That is, the effect is obtained at a pH (7.2) close to the pH of the blood (around 7.4). Naturally oily (hydrophobic)
Has the property of changing a substance that should be to water-soluble (hydrophilic). They are blood purification and blood vessel dilation, biochemical reduction, detoxification, sterilization, dechlorination, and enzymatic proteolysis. In particular, among the above, the effects in which the skin protective agent is effectively used as cosmetics are vasodilating effects, biochemical reducing effects, bactericidal effects, and enzymatic proteolytic effects. The Hosenka alcohol extract may be used alone as a skin protectant, but it can be more effective when mixed with other cosmetics or baths. When the Fengxiang Alcohol extract is used alone as a skin protective agent, the Fengxian Alcohol extract is mixed with a water-soluble polymer to form a jelly-like cream. When the skin protective agent of the present invention is used as a mixture with cosmetics, 0.5 to 2 parts by weight of the Fengxian flower alcohol extract is added to 10 parts by weight of the cosmetics. When using the Fengxian alcohol extract as a bathing agent, add 3 to 7 ml to the bathtub. When the skin protective agent of the present invention is used in a mixture with a bathing agent, 1-2 parts by weight of an alcohol extract of Fengseng flower is added to 10 parts by weight of the bathing agent.

Hereinafter, examples and test examples will be described.

Example 1 A white liquor containing an extract of the whole plant of Fengxian flower was obtained by shading the whole plant of Fengxian flower in 150 kg of 35 ° C white liquor in a shade of 50 kg, which was dried for 1 month. This was filtered and diluted to 20 ° C with distilled water to obtain an alcohol extract of Fengxian flower.

Example 2 A water-soluble polymer was mixed with 300 g of an alcoholic extract of Hosenhana to form a jelly-like cream.

Example 3 300 g of lemon is cut into 1 kg of alcoholic extract of Fengxian flower and left for 1 to 2 weeks. The mixed solution was separated into a filtrate and a residue by filtration, and the filtrate was used as a lemon / Fengseng flower alcohol extract and mixed with a water-soluble polymer to form a jelly-like cream.

Test Example 1 A 20-year-old housewife (age 25-30 years) using the skin protective agent of the present invention of Example 2 was tested for the moisturizing property of the skin by one test.
It was performed for 0 consecutive days. Every day, when I sleep at night, I put a skin protectant on my right hand, left my left hand on nothing, did normal work and measured the dryness of my right and left hands with an instrument.
As a result, all of the 20 people had their right hands moisturized normally, but their left hands were dry and bulky.

Test Example 2 30 persons (age 2) using the skin protective agent of the present invention of Example 2
Men and women were tested to see the effect of sunscreen. A skin protectant was applied to the right hand, and the left hand was placed without any object. The backs of both hands were exposed to sunlight for 5 hours from 10 am to 3 pm, and the states of erythema of the right and left hands were compared. As a result, all 30 persons did not have erythema on the right hand, but had erythema on the left hand, and there was a clear difference. Also,
For comparison, an experiment was carried out on the right hand and the left hand using a commercially available sunscreen cream and the skin protective agent of the present invention, but there was no difference between the right hand and the left hand.

Test Example 3 Twelve women (age 2) using the jelly-like cream of Example 3 (containing 30% alcohol extract of lemon and phoenix flower)
(5 to 35 years old) every night for 30 days, covered with a wrap, covered with a steamed towel and allowed to cool down for a while, then examined for stains and freckles. As a result, the spots and freckles disappeared, and 9 people felt that the color became whiter than before, the spots and freckles became thinner,
Three people felt slightly white. Everyone felt the skin was clean. The riding condition of makeup has also improved.

[0013]

The alcohol extract of Fengxian flower is an extract of a plant, and contains NMF (natur) in the stratum corneum of human skin.
al moisturizing factor (natural moisturizing factor) It contains the same amino acids as 40% of the composition and contains citric acids, so it is an optimal skin protectant for protecting skin moisturizers, cosmetics and bath salts. It is more effective if used together. In addition, 234 nm, 248 nm, 261
There are strong maximum absorption spectra around nm, 270 nm and 325 nm. Therefore, 290-3 causing erythema of the skin
It absorbs 20 nm ultraviolet rays (Dornow line) and also absorbs wavelengths around 260 nm, which cause skin cancer, so it is a skin protective agent that cuts off harmful ultraviolet rays and can be used as suntan cosmetics. In addition, there is a feature that the effect lasts forever. In particular, the effects that are effective when the skin protective agent of the Hosenka alcohol extract is added to cosmetics and bath preparations are vasodilatory, biochemical reducing, bactericidal, and enzymatic proteolytic activities. As a result, the vasodilating action improves blood circulation on the surface of the skin and rejuvenates the skin. Enzymatic proteolysis acts to loosen the surface tissue of the skin and promotes the absorption of the medicinal components of cosmetics and bath salts from the skin surface. Not only does the bactericidal action keep the skin surface clean, but there is no need to add preservatives to the product. Since oxidation is prevented by a biochemical reducing action, there is no need to add an antioxidant to cosmetics and bath salts. In addition, in the case of cosmetics utilizing the whitening effect of vitamin C, if a skin protective agent is used together, the oxidation of vitamin C is prevented by the biochemical reduction action, and the vitamin C penetrates into the skin by the enzymatic protein decomposition action. And the beauty effect that the color becomes whiter more quickly than before is strong.
