【発明の属する技術分野】
本発明は皮膚用の化粧料に関し、さらに詳しくは使用時の感触が軽く使用後もべたつかず、保湿効果、保湿効果の持続性、肌荒れ改善効果およびしわとり効果に優れるとともに肌にはりを与え、経時安定性にも優れる保湿化粧料に関する。
【0002】
【従来の技術】
通常、人の皮膚表面は皮脂膜に覆われていて水分の蒸散が適度に抑制されている。皮膚の水分を適切な範囲に保つことは皮膚の健康の面から見て非常に大切なことであり、水分が不足すると肌荒れ等を生じやすくなる。特に洗顔や入浴を行うと一時的に皮脂膜が取り除かれてしまい肌の水分が失われやすくなることから化粧水、乳液、クリーム、美容液等の保湿化粧料を使用して水分を補う必要がある。
一般に保湿化粧料には保湿剤としてグリセリン、1,3−ブチレングリコール、ソルビトール等の多価アルコールやピロリドンカルボン酸塩等が配合されているが、これらは高湿度下における水分保持力には優れているものの低湿度下における水分保持力に難があり、保湿効果の持続性が保てなかった。そこで近年、低湿度下での水分保持力の高い保湿成分としてキチン、キトサンおよびそれらの誘導体、蛋白加水分解物、ヒアルロン酸等の酸性ムコ多糖類、植物抽出物等様々な物質が研究されているが、これら保湿力の高い保湿成分は不快なべたつきを有しており感触が重くなるという欠点があった。その中で、アンズ、リンゴ等のバラ科植物果実の果汁はビタミン、α−ヒドロキシ酸、ミネラル等の様々な植物性活性要素を含有しており、新陳代謝を活発にするとともに収斂作用や高い保湿作用を有していることが公知である。これらを使用した化粧料としては特開昭55−19205号公報および特開平9−175982号公報記載の化粧料がある。
【0003】
一方、木通(モクツウ)はアケビまたはその他同属植物であり、蔓性の茎を採取し、輪切りにして乾燥させたもの等を古来より漢方薬の成分として用いられてきた生薬である。この生薬はストレス胃潰瘍発生予防効果(薬第95巻第1179頁 1975年)、利尿作用(Chem. Phar. Bull. 第27巻第1464頁 1979年)、抗炎症作用(日本薬学会90年会発表講演要旨集1970年)を有することが公知である。さらに、特開平10−7581号公報において木通の抽出エキスが皮膚保湿能力を高める作用を有することが示されており、木通抽出エキスを含有した保湿効果の高い皮膚外用剤が提案されている。しかし、これらバラ科植物果実果汁や木通抽出エキスを配合した化粧料や皮膚外用剤は、経時で着色や沈殿を生じたりして安定性が悪いだけでなく、肌荒れ改善効果や肌にはりを与える効果が弱かった。
【0004】
【発明が解決しようとする課題】
本発明は上記課題を解決し、使用時の感触が軽く使用後もべたつかず、保湿効果、保湿効果の持続性、肌荒れ改善効果およびしわとり効果に優れるとともに肌にはりを与え、経時安定性にも優れる保湿化粧料を提供することを目的とする。
【0005】
【課題を解決するための手段】
上記課題を解決する為に研究を重ねたところ、特定の植物果実果汁と植物抽出エキスを特定の比率で組み合わせることで目的の保湿化粧料を得るに至った。
すなわち本発明は、a.木通(モクツウ)の抽出エキスを乾燥残留物として0.00005〜2重量%、b.バラ科植物果実果汁0.01〜60重量%含有することを特徴とする保湿化粧料である。
【0006】
【発明の実施の形態】
本発明に用いられる木通の抽出エキスは、木通の蔓性の茎をそのままもしくは乾燥後に炭化水素、エステル、ケトン、エーテル、ハロゲン化炭化水素、アルコール、および水から選ばれる1種または2種以上と共に加熱還流あるいは浸漬して得られるが、好ましくは水またはエタノール、プロピルアルコール、イソプロピルアルコール、ブタノールなどの低級アルコールの1種または2種以上で抽出したものであり、更に好ましくは水で抽出したものである。本発明の木通の抽出エキスとは抽出溶液そのものもしくはその濃縮物を言う。
【0007】
本発明に用いられるバラ科植物果実としては例えばリンゴ、アンズ、モモ、スモモ、ナシ、ビワ、ウメ、イチゴ、キイチゴ、ヘビイチゴ、オランダイチゴ、オヘビイチゴ、トックリイチゴ、シマバライチゴ、エビガライチゴ、フユイチゴ、カリン等があり、好ましくはリンゴ、アンズ、モモ、ナシ、イチゴであり、より好ましくはリンゴ、アンズである。そして、これらの果実を圧搾して液汁を得たりその液汁を濃縮したりして果汁を得る。
【0008】
本発明のa.成分である木通の抽出エキスは組成物全量中に乾燥残留物として0.00005〜2重量%含有され、好ましくは0.0001〜1.5重量%、更に好ましくは0.0005〜1重量%含有される。0.00005重量%未満では保湿効果の持続性、肌荒れ改善効果およびしわとり効果が弱くなり、2重量%を超えると経時安定性に問題を生じるだけでなくコスト的に不利である。ただし、本発明でいう乾燥残留物とは通常抽出エキスを105℃で乾燥して溶媒を除去した時の残留物である溶質を指すが、抽出溶媒が不揮発性の場合にはガスクロマトグラフや高速液体クロマトグラフ等により溶媒量を定量した値から溶質量を計算値として求め、乾燥残留物量と見なす。
【0009】
本発明のb.成分であるバラ科植物果実果汁は組成物全量中に0.01〜60重量%であり、好ましくは0.05〜50重量%、更に好ましくは0.1〜40重量%である。0.01重量%未満では肌荒れ改善効果および肌にはりを与える効果が弱くなり、5重量%を超えるとべたつきを有して感触が悪くなり、しかも経時安定性に問題を生じる。ただし、上記の配合量範囲は果汁100%とした時の範囲であり、濃縮果汁を使用する場合にはその濃縮率から配合範囲を換算した値とする。
【0010】
なお、本発明の皮膚化粧料には、化粧料に常用されている添加剤を本発明の性能を損なわない範囲で配合することも可能である。例えばエタノール、プロピルアルコール、イソプロピルアルコール、ブタノール等の低級アルコール、プロピレングリコール、ジプロピレングリコール、グリセリン、ジグリセリン、1,3−ブチレングリコール、ポリエチレングリコール等の多価アルコール、流動パラフィン、流動イソパラフィン、スクワラン、ワセリン、固形パラフィン等の炭化水素系油、牛脂、豚脂、魚油等の天然油脂、トリ−2−エチルヘキサン酸グリセリル等の合成トリグリセライド、ミリスチン酸イソプロピル、パルミチン酸イソプロピル、パルミチン酸セチル、オレイン酸エチル、オレイン酸オレイル、ミリスチン酸オクチルドデシル等のエステル油、ミツロウ、カルナバロウ等のロウ、直鎖および環状のジメチルポリシロキサン、ポリエーテル変性ジメチルポリシロキサン、アミノ変性ジメチルポリシロキサン等のシリコーン誘導体、セラミド、コレステロール、蛋白誘導体、ラノリン、ラノリン誘導体、レシチン等の油性基剤、せっけん、アシルメチルタウリン塩、アミドエーテル硫酸エステル塩等の陰イオン性界面活性剤、アミドアミノ酸塩、アミドプロピルジメチルアミノ酢酸ベタイン等の両性界面活性剤、ポリオキシエチレンアルキルエーテル、ポリエチレングリコールの脂肪酸エステル、ソルビタン脂肪酸エステル、ポリオキシエチレンソルビタン脂肪酸エステル、ポリオキシエチレン硬化ひまし油、ポリグリセリン脂肪酸エステル、ポリオキシエチレングリセリン脂肪酸エステル、グリセリンモノ脂肪酸エステル、アルキルポリグルコシド、アルカノールアミド等の非イオン性界面活性剤、塩化アルキルトリメチルアンモニウム等の陽イオン性界面活性剤、アルキルジメチルアミンオキシド等の半極性界面活性剤、アルギン酸、カルボキシビニルポリマー、カルボキシメチルセルロース、ヒドロキシプロピルメチルセルロース、ヒドロキシエチルセルロース、キサンタンガム等の水溶性高分子、ピロリドンカルボン酸塩、クエン酸塩、リンゴ酸塩、食塩等の有機または無機塩、pH調製剤である酸およびアルカリ、殺菌剤、キレート剤、抗酸化剤、紫外線吸収剤、動植物由来の天然エキス、色素、香料等を配合できる。

BACKGROUND OF THE INVENTION
The present invention relates to a cosmetic for skin, more specifically, it has a light touch during use and is not sticky after use, and is excellent in moisturizing effect, durability of moisturizing effect, skin roughening improving effect and wrinkle removing effect, The present invention relates to a moisturizing cosmetic that is also excellent in stability over time.
[0002]
[Prior art]
Usually, the surface of human skin is covered with a sebum film, and the transpiration of water is moderately suppressed. Keeping the skin moisture within an appropriate range is very important from the viewpoint of skin health. If the moisture is insufficient, rough skin and the like are likely to occur. Especially when you wash your face or take a bath, the sebum film will be temporarily removed and it will be easy to lose the moisture of your skin, so it is necessary to supplement the moisture with moisturizing cosmetics such as lotion, milky lotion, cream, and beauty serum. is there.
In general, moisturizing cosmetics contain polyhydric alcohols such as glycerin, 1,3-butylene glycol, sorbitol, and pyrrolidone carboxylates as moisturizers, but these are excellent in moisture retention at high humidity. However, it was difficult to retain moisture under low humidity, and the moisturizing effect could not be maintained. Therefore, in recent years, various substances such as chitin, chitosan and their derivatives, protein hydrolysates, acidic mucopolysaccharides such as hyaluronic acid, plant extracts, etc., have been studied as moisturizing components with high moisture retention at low humidity. However, these moisturizing components having high moisturizing power have an unpleasant stickiness and have a drawback that the feel becomes heavy. Among them, fruit juices of roses such as apricots and apples contain various plant active elements such as vitamins, α-hydroxy acids, minerals, etc., and they are active in metabolism and have an astringent action and high moisturizing action. It is known to have Cosmetics using these include cosmetics described in JP-A-55-19205 and JP-A-9-175982.
[0003]
On the other hand, Mokutsu is an akebi or other related genus plant, which is a herbal medicine that has been used as a component of traditional Chinese medicine since vine stems were collected, cut into slices and dried. This herbal medicine prevents stress gastric ulcer development (Drug 95, 1179, 1975), diuretic action (Chem. Phar. Bull. 27, 1464, 1979), anti-inflammatory action (announced at the 90th Annual Meeting of the Pharmaceutical Society of Japan) It is known to have a collection of lecture abstracts 1970). Furthermore, JP-A-10-7581 discloses that an extract from Kitsutsu has an action to enhance the skin moisturizing ability, and a skin external preparation having a high moisturizing effect containing the extract from Kotsu is proposed. . However, cosmetics and topical skin preparations that contain these Rosaceae fruit juices and tree extract extract not only have poor stability due to coloration and precipitation over time, but also have an effect of improving skin roughness and skin tone. The effect it gave was weak.
[0004]
[Problems to be solved by the invention]
The present invention solves the above-mentioned problems, feels light during use and is not sticky after use, has a moisturizing effect, durability of the moisturizing effect, excellent skin roughening effect and wrinkle removal effect and gives a skin tone, and is stable over time. It aims to provide an excellent moisturizing cosmetic.
[0005]
[Means for Solving the Problems]
When research was repeated in order to solve the said subject, it came to obtain the target moisturizing cosmetic by combining a specific plant fruit juice and a plant extract in a specific ratio.
That is, the present invention relates to a. 0.00005-2 wt% of extract of Mokutsu as a dry residue, b. A moisturizing cosmetic characterized by containing 0.01 to 60% by weight of a rose fruit juice.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
The extract of the tree-deck used in the present invention is one or two kinds selected from hydrocarbons, esters, ketones, ethers, halogenated hydrocarbons, alcohols, and water after or after drying the vine vine stems. It is obtained by heating under reflux or immersion with the above, preferably extracted with water or one or more of lower alcohols such as ethanol, propyl alcohol, isopropyl alcohol, butanol, and more preferably extracted with water. Is. The tree extract of the present invention refers to the extraction solution itself or its concentrate.
[0007]
Examples of the fruit of the Rosaceae plant used in the present invention include apples, apricots, peaches, plums, pears, loquats, ume, strawberries, raspberries, snake strawberries, Dutch strawberries, snake strawberry, tock strawberries, striped strawberry, shrimp strawberry, shrimp strawberry, karin and the like. Yes, preferably apple, apricot, peach, pear and strawberry, more preferably apple and apricot. Then, these fruits are squeezed to obtain a juice or concentrated to obtain a juice.
[0008]
A. The extract of the woody extract, which is a component, is contained as a dry residue in the total amount of 0.00005 to 2% by weight, preferably 0.0001 to 1.5% by weight, more preferably 0.0005 to 1% by weight. Contained. If the amount is less than 0.00005% by weight, the durability of the moisturizing effect, the rough skin improving effect and the wrinkle removing effect are weakened. However, the dry residue as used in the present invention refers to a solute that is a residue when the extract is usually dried at 105 ° C. to remove the solvent, but when the extract solvent is non-volatile, a gas chromatograph or a high-performance liquid is used. The dissolved mass is obtained as a calculated value from the value obtained by quantifying the amount of solvent by a chromatograph or the like, and is regarded as the dry residue amount.
[0009]
B. The rose fruit fruit juice which is a component is 0.01 to 60 weight% in the whole composition, Preferably it is 0.05 to 50 weight%, More preferably, it is 0.1 to 40 weight%. If the amount is less than 0.01% by weight, the effect of improving rough skin and the effect of giving the skin are weakened. If the amount exceeds 5% by weight, the surface becomes sticky and feels bad, and the stability with time is problematic. However, the above-mentioned blending amount range is a range when the fruit juice is 100%, and when concentrated fruit juice is used, the blending range is converted from the concentration ratio.
