The present invention relates to a skin cosmetological composition containing an acetic acid extract of onion bulbs.

As used herein, the term "skin beauty composition" means a composition for maintaining or improving the condition of the skin of a user and maintaining or enhancing the aesthetic appearance of the skin. Specific examples thereof include improvement of wrinkles, prevention and improvement of skin aging, improvement of skin firmness and texture, and impartation of transparency. The skin cosmetological composition of the present invention has a particularly excellent effect on improving wrinkles as shown in Examples.

Hereinafter, the skin beauty composition of the present invention will be described in more detail.

The onion scale acetic acid extract contained in the skin beauty composition of the present invention is an acetic acid extract of bulbs of onion (scientific name: Allium cepa).
Onions are perennials of the genus Allium of the Liliaceae family, and their bulbs are widely used for food. Onion bulbs are traditionally said to have medicinal properties such as diuretic action and antibacterial action, and are also said to have antioxidant action, anti-aging action and anti-allergic action.

The type of onion used as a raw material is not particularly limited, and any of yellow onion, white onion, and purple onion can be used.

In the present invention, the "extract" is a concept that summarizes the onion bulbs to be extracted, or the ones in which the onion bulbs to be extracted are extracted with a solvent as necessary to increase the content of the active ingredient. Is. Specifically, it includes an extract obtained from onion scales as an extraction raw material, a diluted solution or a concentrated solution of the extract, or a crude or purified product thereof. The dried product obtained by drying the extract also corresponds to the extract.

As shown in the examples, the active ingredient contained in the onion bulb that contributes to skin cosmetology is a component soluble in acetic acid.
As the extraction solvent, acetic acid alone may be used, or hydrous acetic acid, which is an easily available mixture of acetic acid and water, may be used. The water that can be used as the extraction solvent includes purified water, ion-exchanged water, physiological saline and the like.

In the case of hydrous acetic acid, the mixing ratio of acetic acid and water can be appropriately adjusted as long as the effect of the present invention (skin beauty effect such as wrinkle improvement) is not impaired, but the acetic acid concentration is usually 1 to 50% by weight. ..
The hydrous acetic acid may be synthetic vinegar or brewed vinegar, but brewed vinegar is preferable. Synthetic vinegar and brewed vinegar can be appropriately concentrated to a predetermined acetic acid concentration or diluted with water before use.
Brewed vinegar is an edible acetic acid aqueous solution produced by acetic acid fermentation of grain vinegar (rice vinegar, brown rice vinegar, rice black vinegar, barley black vinegar, etc.) and fruit vinegar (apple vinegar, grape vinegar, etc.) that are commercially available as so-called vinegar. Is. Among these, rice vinegar and apple cider vinegar contain useful components such as organic acids and polyphenols other than acetic acid, and are therefore suitable as an extraction solvent for the onion scale acetic acid extract of the present invention.
Commercially available products of rice vinegar and apple cider vinegar can be preferably used, and they may be used alone or in combination. The mixing ratio (volume ratio) when rice vinegar and apple cider vinegar are mixed is preferably rice vinegar: apple cider vinegar = 10: 90 to 90:10.

Further, the extraction solvent may contain a solvent other than acetic acid and water as long as the effect of the present invention is not impaired. Specific examples include lower alcohols having 1 to 5 carbon atoms such as water, ethanol, propyl alcohol and isopropyl alcohol; organic acids such as formic acid, butyric acid, oxalic acid, malic acid, lactic acid, tartrate acid, citric acid and succinic acid; 1 , 3-Butylene glycol, propylene glycol, glycerin and other polyhydric alcohols having 2 to 5 carbon atoms can be mentioned. Moreover, the extraction solvent may contain an additive. For example, a viscosity modifier and the like can be mentioned.

The skin cosmetological composition of the present invention preferably contains baking soda together with the onion bulb acetic acid extract. Baking soda (sodium hydrogen carbonate) is a sodium hydrogen carbonate represented by the _{chemical formula NaHCO 3, which is alkaline when dissolved in water.}

As shown in the examples, wrinkle improvement, moisturizing effect, and skin-beautifying effect (improvement of texture) are observed only with the onion bulb acetic acid extract, but by containing baking soda together, better skin beauty in a shorter period of time is observed. The effect (especially wrinkle improvement) is recognized. The details of the improvement of the skin beauty effect by combining the onion bulb acetic acid extract and baking soda are unknown, but as shown in the examples, the water extract of the onion bulb rather deteriorates the skin beauty effect. From this, it is speculated that the acetic acid-soluble component contained in the onion bulbs and the baking soda have a synergistic effect.

The content of the onion bulb acetic acid extract and baking soda in the skin beauty composition of the present invention may be appropriately contained within the range in which the effect is exhibited. When a mixture of rice vinegar and apple cider vinegar is used as the extraction solvent, the amount of baking soda is 0.1 to 1 g per 100 mL of the onion bulb extract.

<Other ingredients>
The skin cosmetological composition of the present invention may contain other components other than the onion bulb acetic acid extract and baking soda as long as the object of the present invention is not impaired. The other ingredients are not particularly limited as long as they are pharmaceutically or cosmetically acceptable ingredients.

For example, bisabolol, vitamin C or a vitamin C derivative, rice bran extract, and prune yeast decomposition extract may be contained as components that promote the whitening effect.

In addition, it may contain Himefuuro extract, yeast polysaccharide, red wine yeast, chamomile extract and the like, which are components that promote skin turnover.

Further, as a moisturizing component, human ceramide, hyaluronic acid (sodium hyaluronate, acetylated hyaluronic acid, hydrolyzed hyaluronic acid, etc.) and the like may be contained.

<Form and usage of skin beauty composition>
The form of the skin beauty composition of the present invention is not limited as long as it can be applied to human skin, and is appropriately determined according to the method of use, such as a lotion, a lotion, a gel, a milky lotion, and a cream. Can be used in various forms of. Among these, it is preferable to use it as a lotion because of its applicability to the skin including the face.

When the skin beauty composition of the present invention is used as a cosmetic water (aqueous solution), the solvent is water (preferably purified water), and a component used in a conventionally known cosmetic water is blended therein. May be good. For example, any component such as ethanol, glycerin, antioxidant, whitening agent, ultraviolet absorber, solubilizer, moisturizer, dye, pH adjuster, emulsifier, thickener, fragrance, etc. impairs the effect of the present invention. It can be contained in any compounding ratio within a range that does not exist.

The skin beauty composition of the present invention may be produced by a generally known method depending on its form. For example, when the form is cosmetic water, it can be produced by mixing an onion bulb acetic acid extract, baking soda, and water (and, if necessary, other components such as glycerin) in a desired ratio.

The skin cosmetological composition of the present invention typically indicates that any one of the main body, packaging, instruction manual, and advertising material (including WEB page) of the product according to the present invention has a skin cosmetological effect. use.

The skin beauty method of the present invention is characterized by including a step of applying the skin beauty composition of the present invention to the skin (however, excluding medical practice). Depending on the form of the skin beauty composition of the present invention, it may be applied directly or sprayed. Typically, as a treatment in an aesthetic salon or the like where medical treatment is not performed, a method of applying the skin beauty composition of the present invention to the skin of a subject can be mentioned.

Hereinafter, the present invention will be described in more detail with reference to examples, but the present invention is not limited thereto.

<Experimental Example 1>
After removing the epidermis of 2 yellow onions (about 600 g), the bulbs were sliced. Add sliced onion scales to 450 mL of vinegar mixture as an extraction solvent (mixture consisting of 225 mL of rice vinegar (trade name: Mitsukan Pure Rice Vinegar) and 225 mL of apple cider vinegar (trade name: Mitsukan Pure Rice Vinegar)). After immersing and allowing to stand at room temperature (about 20 ° C.) for 12 hours, the solid content was removed to obtain an onion vinegar vinegar acetic acid extract (stock solution) of Experimental Example 1.

<Experimental Example 2>
The composition of Experimental Example 2 was prepared by producing an onion bulb acetic acid extract in the same manner as in Example 1, adding 2 g of baking soda to 400 mL of the obtained onion bulb acetic acid extract, and stirring the mixture until the mixture was completely dissolved. (Undiluted solution) was obtained.

<Experimental Example 3> (Comparative Example)
The composition (stock solution) of Experimental Example 3 was obtained by adding 2 g of baking soda to 400 mL of water and stirring until the mixture was completely dissolved.

<Experimental Example 4> (Comparative Example)
A water extract of onion bulbs was obtained in the same manner as in Example 1 except that 400 mL of water was used instead of 400 mL of the mixed solution of vinegar as the extraction solvent.
The composition (stock solution) of Experimental Example 4 was obtained by adding 2 g of baking soda to 400 mL of the obtained water extract of onion bulbs and stirring until the mixture was completely dissolved.

(Adjustment of lotion)
40 mL of the above composition (stock solution) of Experimental Examples 1 to 4 was mixed with 50 mL of purified water and 10 mL of glycerin to obtain a lotion of Experimental Examples 1 to 4.

(Monitor test)
Experimental examples 1 to 8 monitors (2 in their 20s (male and female), 2 in their 30s (male and female), 1 in their 50s (female), 2 in their 60s (male and female), 1 in their 70s (female)) The lotion of No. 4 was used on the face once a day for 5 weeks, and the condition of the skin after use was evaluated.
Table 1 shows the evaluation results at the 3rd and 5th weeks. In addition, FIG. 1 (3rd week) and FIG. 2 (5th week) show the summary of the monitor test questionnaire that was the basis of Table 1, respectively.

The evaluation criteria are as follows.
<Wrinkle improvement>
2 points: Most of the effects could be confirmed 1 point: Some effects could be confirmed 0 points: No effect could be confirmed -1 point: Wrinkles and sagging increased -2 points: Abnormalities appeared on the skin, etc. <Moisturizing effect>
2 points: Confirmation of moist feeling 1 point: Confirmation of slightly moist feeling 0 points: No effect confirmed -1 point: Dry / taut feeling -2 points: Abnormal skin, etc. <Skin-beautifying effect (skin texture)>
2 points: Most of the effects could be confirmed 1 point: Some effects could be confirmed 0 points: No effect could be confirmed -1 point: The texture became rough -2 points: Abnormalities appeared on the skin, etc.

As shown in Table 1, in Experimental Examples 1 and 2 containing the onion bulb acetic acid extract, wrinkle improvement, moisturizing effect, and skin-beautifying effect were all observed. In Experimental Example 2 (onion bulb acetic acid extract and baking soda), it was confirmed that wrinkle improvement, moisturizing effect, and skin-beautifying effect were superior to Example 1 (onion bulb acetic acid extract only) from the third week (onion). Especially wrinkle improvement). On the other hand, in Experimental Example 3 (aqueous solution of baking soda), which is a comparative example, no wrinkle improvement, moisturizing effect, or skin-beautifying effect was observed. In addition, in Experimental Example 4 (onion bulb water extract and baking soda) in which acetic acid was not used as the extraction solvent, no wrinkle improvement, moisturizing effect, or skin-beautifying effect was observed, and an abnormality occurred in the skin at the third week. Since there were multiple monitors, the evaluation was stopped at that point.

From the above results, wrinkle improvement, moisturizing effect, and skin-beautifying effect (improvement of texture) are observed only with the onion bulb acetic acid extract of Experimental Example 1, but by containing baking soda together as in Experimental Example 2, It was found that a better skin beauty effect (especially wrinkle improvement) was observed in a shorter period of time. In addition, as shown in Experimental Example 4, the water extract (and baking soda) of onion bulbs rather reduces the skin beauty effect and adversely affects the skin. Therefore, the acetic acid-soluble component contained in the onion bulbs and the baking soda are synergistic. It is considered that the action is produced and a more excellent skin beauty effect is exhibited.
