Description

  The present invention relates to a moisturizing cosmetic composition comprising a ball bamboo powder obtained by pulverizing ball bamboo (Polygonatum Officinale).

  Skin (skin), which plays an important role as a barrier that protects the living body from the external environment, forms a thin stratum corneum containing moisture through differentiation processes in the epidermis layer in order to prevent moisture loss. . This stratum corneum is located in the outermost stratum corneum of the skin that is in direct contact with the external environment, prevents the entry of physically and chemically harmful components into the living body, and is a dry environment from the living body. Even underneath, it prevents water loss in the body, and the stratum corneum itself retains flexibility by holding moderate water. The moisture content of the skin is about 70% in the dermis, but the moisture content decreases as it moves to the epidermis side, and is about 10% to about 30% in the stratum corneum of the outermost horny layer. When moderate moisture is retained in the stratum corneum, the elasticity and flexibility of the skin is maintained, and generally normal skin contains about 30% moisture and water-soluble components. Yes. In addition, high concentrations of natural moisturizing factors (NMF) are present in the horny cells of healthy people, which assists the moisture retention of the skin.

  Despite this function, the skin is exposed to the harsh external environment, i.e. wind and rain, cold weather, sunlight, etc., as well as facial cleansing, shaving, winter indoor heating, and contaminated atmosphere. In addition, the skin moisture is easily lost due to factors such as aging as aging progresses, and the skin becomes easy to dry, so there is a long-awaited skin moisturizer that prevents this phenomenon. Yes.

  There are many substances that show moisturizing effects, and research to deal with such phenomena has been actively conducted, so far, it has been used for skin that can increase the amount of moisture in the stratum corneum. Known moisturizer components include lipid components such as ceramide, essential fatty acids and lipid complexes (see Non-Patent Document 1).

  Recently, coupled with the growing interest in Kampo, active research is being conducted to obtain useful ingredients for the human body from natural herbal medicines that are safe for the human body.

  Since ancient times, the concept of prosthetic shadow has been widely used in traditional Chinese medicine, but when this concept is applied to modern human skin, it is closely related to the moisturizing action of the skin. Moisturizing the skin is also a method for dealing with wrinkles caused by skin dryness, which is the most serious problem in realizing a desirable skin condition.

  Polygonatum Officinale, one of the herbal medicines that have a prosthetic effect among herbal medicines, is used for medicinal rhizomes for medicinal purposes.

Amadokoroko, the origin of the bamboo, is a perennial herb. The rhizome, the bamboo, is harvested in the fall or early spring, and the stem and roots are removed and dried in the shade or steam. What was exposed to water and dried in the sun is used for medicinal purposes. Jade bamboo contains various flavonoids as well as steroidal saponins such as convallamarin and convallarin as medicinal ingredients. It is known to exhibit cardiotonic action, action similar to corticosteroids, action to relieve thirst, antioxidant action, skin aging action, and the like. In oriental medicine, the taste of this medicine is "flat", "sweet", and it is effective for nourishment, pulmonary lungs, thirst, etc., for symptoms such as weak constitution, thirst, diabetes, angina Take in the form of a liquid, pill or powder.

  In addition to jade bamboo, there are many herbal medicines that are well-known herbal medicines but are difficult to use as cosmetic ingredients. For such herbal medicines, an extract obtained by extraction with water ( Extract liquid) is often used. However, in general, since it is difficult to obtain a large amount of a homogeneous herbal extract, the actual situation is that it has not yet been possible to efficiently obtain the medicinal components of Chinese herbal medicine.

  In view of the technical problems recognized in the above-described prior art, the inventors of the present application conducted intensive research on a cosmetic composition that can be easily obtained and used while containing a large amount of bamboo. The powdered ball bamboo contains a larger amount of useful components than the ball bamboo extract, and it has been found that it can be easily incorporated into a cosmetic composition. That is, the gist of the present invention resides in a moisturizing cosmetic composition containing a ball bamboo powder obtained by grinding ball bamboo.

  According to the present invention, a cosmetic composition containing a large amount of useful components contained in cypress, which was the intended purpose, that is, a cosmetic composition having an excellent moisturizing effect on human skin. Is realized.

  The configuration of the present invention will be described in detail below.

  Since the moisturizing cosmetic composition of the present invention incorporates a large amount of bamboo and bamboo powder, it exhibits an excellent moisturizing effect on human skin.

  In the moisturizing cosmetic composition of the present invention, it is preferable to blend ball and bamboo powder at a concentration of about 0.01 wt% to about 30 wt%. In other words, if the content of onion and bamboo powder is less than about 0.01% by weight, the desired skin moisturizing effect cannot be obtained. Is excessively strong and may lead to a reduction in quality as a cosmetic product.

  Even if it is going to mix | blend an extract of a cypress with a cosmetics composition, generally the compounding quantity has a limit and it does not reach the compounding quantity at the time of using a bamboo and bamboo powder. For example, in the case of using a 10% onion extract, the content of the onion (stock solution) is only 10%. The bamboo content is only 1%. On the other hand, by using the ball and bamboo powder obtained by crushing the ball and bamboo, a large amount of ball and bamboo can be added directly and easily into the preparation, so it has excellent moisture retention for human skin. The effect can be expected.

  The moisturizing cosmetic composition of the present invention can be obtained by the following method.

  First, the cultivated raw ball bamboo is dried, and the dried ball bamboo is heated and roasted, and then applied to a pulverizer, where it is finely pulverized to obtain a powder, that is, ball bamboo powder. In the present invention, an animal experiment and a practicality test were performed in order to verify the moisturizing effect based on the content of the bamboo and bamboo powder thus obtained. In other words, when measuring the epidermal water loss (TEWL) of animal or human skin (skin), the moisturizing effect increases with the increase of the bamboo and bamboo powder content, improving the moisturizing effect. It became clear that it was done.

  In other words, the present invention provides a moisturizing cosmetic composition suitable for use as a skin moisturizing agent, comprising the ball and bamboo powder obtained by the above-described method.

  The moisturizing cosmetic composition of the present invention, in addition to the above-mentioned onion and bamboo powder, further contains other moisturizing ingredients that assist or improve these functions and effects as long as the effects of the present invention are not substantially impaired. It can also be added. Such components include, but are not limited to, ceramide, glycerol, glycerin and the like.

  The ball bamboo powder used in the moisturizing cosmetic composition of the present invention can be applied as it is in the form of a spring, a spring, a spring or a dry powder of the spring, or a normal external preparation or It can also be in the form of cosmetics.

  The moisturizing cosmetic composition of the present invention containing ball and bamboo powder can be used in various products such as cosmetics, facial cleansers, and shampoos for the skin moisturizing effect. The products to which the moisturizing cosmetic composition of the present invention can be added include cosmetics such as various creams, milk lotions, skin lotions, and shampoos, rinses, cleansings, facial cleansers, soaps, treatments, and cosmetics. It is not limited to these.

  Moreover, the moisturizing cosmetic composition of the present invention containing the ball and bamboo powder can be in the form of a solution, an emulsion, a viscous mixture, or the like.

  Examples of products for which the moisturizing cosmetic composition of the present invention can be used include emulsions, creams, lotions, essences, packs, gels, powders, lipsticks, makeup bases, foundations, lotions, ointments, gels, patches, and cosmetics. Examples include, but are not limited to, liquids, cleansing foams, cleansing creams, cleansing water, soaps and sprays.

  It is easy for those skilled in the art to select and incorporate ingredients other than the ball and bamboo powder into the product using the moisturizing cosmetic composition of the present invention according to the cosmetic dosage form or purpose of use. That is.

  For the purpose of further enhancing the moisturizing effect, a substance that promotes absorption into the skin can be used in combination with the moisturizing cosmetic composition of the present invention.

  In addition, water-soluble vitamins, oily vitamins, polymer peptides, polymer polysaccharides, sphingolipids, seaweed extracts, and the like can be added to the moisturizing cosmetic composition of the present invention.

  Furthermore, in addition to the above-described components, the moisturizing cosmetic composition of the present invention can be used in combination with other optional components blended in a normal cosmetic as necessary. As such optional ingredients, oil and fat ingredients, moisturizers, emollients, surfactants, organic pigments, inorganic pigments, organic powders, UV absorbers, preservatives, bactericides, antioxidants, plant extracts, pH adjustment Examples include, but are not limited to, agents, alcohols, pigments, fragrances, blood circulation promoters, cooling agents, antiperspirants, and purified water. The blending amount of these optional components should be an amount that does not substantially impair the action and effect exhibited by the present invention, and preferably about 0.01 wt% to about 5 wt% of the moisturizing cosmetic composition of the present invention, Preferably, the amount is adjusted to about 0.01 wt% to about 3 wt%.

  The present invention will be described below with reference to examples thereof, but it is needless to say that the present invention should not be construed in a limited manner based on the disclosure of the examples.

Example 1: Manufacture of onion and bamboo powder The onion and cultivated raw material was dried. The dried ball bamboo was heated and roasted, and then finely pulverized with a pulverizer to obtain a ball bamboo powder.

Experimental Example 1: Examination of the moisturizing effect of the bamboo and bamboo powder In order to verify the concentration-dependent moisturizing effect of the bamboo and bamboo powder obtained in Example 1, an experiment was performed in the following procedure.

  First, each amount of onion and bamboo powder corresponding to various onion and bamboo concentrations was dispersed in water, and then the epidermal water loss was measured with a water loss measuring device (evaporimeter, ServoMED). In other words, 20 healthy guinea pigs were prepared as experimental animals, and sodium lauryl sulfate (SLS) was applied to any part of the epidermis that appeared after shaving the same part of their backs. Damaged the skin. Next, after applying the bamboo and bamboo powder dispersions of various concentrations (0.01%, 0.1%, 1%, 5%, 10%) to each damaged part, the skin water loss was measured with a moisture evaporation measuring device. It was measured and used as the initial value. Thereafter, a ball bamboo powder dispersion of the same concentration was applied to the damaged part for 4 days, and the value obtained by measuring with a moisture evaporation measuring machine on the 5th day was recorded. The measurement results are shown in Table 1 below.

表１に記載の結果から明らかように、玉竹粉の含量増加に伴う保湿効果の改善を確認することができた。 したがって、玉竹は、抽出物の形態よりも、粉状の形態とすることによって、多量にかつ容易に、直接に製剤内に取り込むことができ、それにより、改善された保湿効果が実現できることが示唆されたのである。

As is apparent from the results shown in Table 1, it was possible to confirm the improvement of the moisturizing effect accompanying the increase in the content of the bamboo and bamboo powder. Therefore, onion can be taken directly into the preparation in a large amount and easily by making it into a powder form rather than an extract form, and thereby an improved moisturizing effect can be realized. It was suggested.

Experimental Example 2: Human skin beauty effect with cosmetics blended with bamboo and bamboo powder In order to verify the beauty effects on human skin with respect to the bamboo and bamboo powder, an experiment was conducted using the following cosmetics.

Experimental Example 2-1 Emulsifier Cosmetic ingredients (raw materials) shown in Table 2 below were prepared. Then, the milk phase component and the water phase component were completely dissolved at 70 ° C., and then emulsification was allowed to proceed for 5 minutes at 7,000 rpm to prepare creamy cosmetic A and cosmetic X.

肌状態があまり良くない20歳〜40歳の30名の女性に対して、クリーム状の玉竹粉含有化粧料Ａを顔面の左側に、そして、クリーム状の玉竹粉不含有化粧料Ｘを顔面の右側に塗布してもらい、５時間後に、肌の潤いについての評価を得ると共に、表皮水分損失量（TEWL）の測定を行い、各化粧料について、二者択一で「好ましい」と選択した人数を集計した。

For 30 women aged 20 to 40 whose skin condition is not so good, apply creamy bamboo powder containing cosmetic A on the left side of the face and creamy bamboo bamboo powder-free cosmetic X Apply to the right side of the face, and after 5 hours, obtain an evaluation of skin moisture and measure the amount of skin water loss (TEWL). For each cosmetic, select “preferred” as an alternative. The number of people who did it was counted.

Experimental Example 2-2: Packing agent Cosmetic ingredients (raw materials) described in Table 3 below were prepared. Then, the aqueous phase component was completely dissolved at 70 ° C. and cooled to 40 ° C., and then the alcohol phase was added and completely dissolved to prepare a solubilized pack agent (Cosmetic B and Cosmetic Y). .

これらパック剤を、肌状態があまり良くない20歳〜40歳の30名の女性の顔面に貼着し、30分後に、これを剥ぎ取った。 パック剤を取り外して５時間後に、肌の潤いについての評価を得ると共に、表皮水分損失量（TEWL）の測定を行った。 なお、実験の正確性を期するべく、この実験を、７日間にわたって、繰り返し実施して、その平均値を求めた。

These packs were applied to the faces of 30 women aged 20 to 40 whose skin condition was not so good, and after 30 minutes, they were peeled off. Five hours after removing the pack, the skin moisture was evaluated and the amount of epidermal water loss (TEWL) was measured. In addition, in order to expect the accuracy of the experiment, this experiment was repeatedly performed over 7 days, and the average value was obtained.

Experimental Example 2-3: Test Results The results of experiments using emulsifiers and pack agents are shown in Table 4 below.

表４に記載の結果から明らかように、５％の玉竹粉を含有する保湿性化粧料組成物で、被検者の70％以上が肌の潤いが豊かになったと実感しており、玉竹粉を含まない化粧料組成物に比べて、保湿効果が有意に改善されていることは、TEWL量の差から歴然であった。

As is clear from the results shown in Table 4, with a moisturizing cosmetic composition containing 5% ball and bamboo powder, more than 70% of the subjects feel that the moisture of the skin has been enriched. It was obvious from the difference in the amount of TEWL that the moisturizing effect was significantly improved as compared with the cosmetic composition not containing bamboo powder.
