Description
【0001】
【発明の属する技術分野】
この発明は、日焼けなどによるシミ,ソバカスに対する皮膚美白効果に優れた美白化粧料に関する。
【0002】
【従来の技術】
従来より、皮膚の色黒,シミ,ソバカス等を改善する上で美白化粧料は非常に関心の深いものであり、これらにおいては、アスコルビン酸,グルタチオン,コロイド硫黄等が有効成分として配合されてきた。また、種々の薬用植物抽出物や、植物由来の没食子酸,ゲラニイン等を用いた例もある。海藻抽出物の美白作用に関する研究も盛んになされており、褐藻抽出物からなる化粧品配合液のメラニン形成阻害物質(特開平1−224308号公報),海藻から抽出したメラニン形成阻害物質(特開平2−88592号公報),褐藻類の親水性溶媒抽出物をチロシナーゼ阻害活性物質として含有する化粧料(特開平2−124810号公報),及び紅藻類スギノリ科ツノマタ属の親水性有機溶媒抽出物を含有する美白化粧料(特開平4−95013号公報)等が開示されている。さらに、コウジ酸やグルコピラノシド誘導体であるアルブチンといった美白成分も最近使用されている。かかる美白成分としては、メラニン産生を触媒するチロシナーゼの活性を阻害するチロシナーゼ活性阻害剤、チロシンからドーパ,ドーパキノン,ドーパクロムを経てメラニンを生成する過程の一部又は全部を阻害するメラニン生合成阻害剤、メラニンの代謝を正常化するメラニン排泄促進剤等が知られている。
【0003】
【発明が解決しようとする課題】
しかしながら、アスコルビン酸は酸化されやすく不安定であり、グルタチオンやコロイド硫黄は特有の異臭や沈殿を生じるという欠点を有する。また従来の薬用植物抽出物や海藻抽出物は効果が不十分であったり、品質が一定しないといった問題点があった。さらに、コウジ酸などにおいてもその安定性の維持等に配慮しなければならなかった。その他にも、連用により副作用の生じるものもあった。
【0004】
本発明は、かかる課題を解決し、メラニン産生抑制効果に優れ、かつ安全性及び安定性の高い美白化粧料を提供することを目的とした。
【0005】
【課題を解決するための手段】
美白化粧料は毎日連用されるものであるため、これに配合する有効成分としては、作用が穏和で、連用により十分な効果を現し、しかも連用による副作用のない物が望まれる。そこで、我々は植物抽出物の中から、有効かつ穏和な皮膚美白作用を有し、更に安定性,安全性も高いものをスクリーニングした。
【0006】
その結果、モウセンゴケ科(Droseraceae)モウセンゴケ属(Drosera L.)から選択される1種又は2種以上の植物の抽出物において、高いメラニン産生抑制作用を見いだした。これらの植物抽出物においては、皮膚刺激性,皮膚感作性といった皮膚への悪影響もなく、また美白化粧料に配合したときも、メラニン産生抑制作用の不活化は起こらずに、品質も安定していた。なお、モウセンゴケ属植物は、葉身の表面に多数の腺毛を有し、粘液を出して小動物を粘着捕食する食虫植物であり、全草が去痰,解毒,鎮痛薬として用いられてきた。モウセンゴケ属植物抽出物の化粧料への用途としては、モウセンゴケ抽出物を有効成分とする抗男性ホルモン剤及びその化粧品への用途(特開平11−180819)が既に開示されている。
【0007】
【発明の実施の形態】
本発明で用いるモウセンゴケ科(Droseraceae)モウセンゴケ属(Drosera L.)の植物として、ナガバノモウセンゴケ(Drosera anglica Huds.),イシモチソウ(Drosera peltata Smith.),モウセンゴケ(Drosera rotundifolia L.),コモウセンゴケ(Drosera spathulata Labill.)が例示され、これらの中でもモウセンゴケ(Drosera rotundifolia L.)及びコモウセンゴケ(Drosera spathulata Labill.)から選択される1種又は2種が美白効果の点で好ましく用いられる。
【0008】
これらのモウセンゴケ属(Drosera L.)植物からの抽出物は、各種の全草又はその葉,樹皮,根,花,枝,果実等の1又は2以上の箇所を生のまま若しくは乾燥させて使用することができ、なかでも全草からの抽出物が効果の点で最も優れている。抽出溶媒としては特に限定されず、水、エタノール,メタノール,イソプロパノール,イソブタノール,n-ヘキサノール,メチルアミルアルコール,2-エチルブタノール,n-オクチルアルコール等の1価アルコール類、グリセリン,エチレングリコール,エチレングリコールモノメチルエーテル,プロピレングリコール,プロピレングリコールモノメチルエーテル,プロピレングリコールモノエチルエーテル,トリエチレングリコール,1,3-ブチレングリコール,へキシレングリコール等の多価アルコール又はその誘導体、アセトン,メチルエチルケトン,メチルイソブチルケトン,メチル-n-プロピルケトン等のケトン類、酢酸エチル,酢酸イソプロピル等のエステル類、エチルエーテル,イソプロピルエーテル,n-ブチルエーテル等のエーテル類、スクワラン,ワセリン,パラフィンワックス,パラフィン油などの炭化水素類、オリーブ油,小麦胚芽油,米油,ゴマ油,マカダミアンナッツ油,アルモンド油,ヤシ油等の植物油脂、牛脂,豚脂,鯨油等の動物油脂などが例示される。また、リン酸緩衝生理食塩水等の無機塩類を添加した極性溶媒、界面活性剤を添加した溶媒を用いることもでき、特に限定されないが、美白化粧料に配合する際の安全性及び効果の点から、水,エタノール,1,3-ブチレングリコールから選択される1種又は2種以上の溶媒を用いることが好ましい。
【0009】
さらに抽出方法としては、室温,冷却又は加熱した状態で含浸させて抽出する方法、水蒸気蒸留などの蒸留法を用いて抽出する方法、モウセンゴケ属植物を圧搾して抽出物を得る圧搾法などが例示され、これらの方法を単独で、又は2種以上を組み合わせて抽出を行う。
【0010】
抽出の際のモウセンゴケ属植物と溶媒との比率は特に限定されないが、モウセンゴケ属植物1に対して溶媒0.1〜1000重量倍、特に抽出操作,効率の点で、0.5〜100重量倍が好ましい。また抽出圧力及び抽出温度は常圧下で0℃から溶媒の沸点以下の範囲とするのが便利であり、抽出時間は抽出温度などにより異なるが2時間〜2週間の範囲とするのが好ましい。
【0011】
このようにして得られたモウセンゴケ属植物の抽出物は、抽出物をそのまま用いることもできるが、その効果を失わない範囲で、脱臭,脱色,濃縮などの精製操作を加えたり、さらにはカラムクロマトグラフィーなどを用いて分画物として用いてもよい。これらの抽出物や精製物,分画物は、これらから溶媒を除去することによって乾固物とすることもでき、さらに、アルコールなどの溶媒に可溶化した形態、或いは乳剤の形態で用いることができる。
【0012】
これらのメラニン産生抑制作用を有するモウセンゴケ属植物抽出物の美白化粧料への配合量は、その効果や添加した際の臭い,色調の点から考え、0.0001〜10重量%の濃度範囲とすることが望ましい。
【0013】
本発明の美白化粧料には、必要に応じて、通常医薬品,医薬部外品,皮膚化粧料及び洗浄料に配合される、油脂,保湿剤,粉体,色素,乳化剤,可溶化剤,洗浄剤,紫外線吸収剤,増粘剤,薬剤,香料,樹脂,アルコール類等を適宜配合することができる。また、本発明の美白化粧料の剤型は任意であり、例えば化粧水などの可溶化系,クリーム,乳液などの乳化系,カラミンローション等の分散系として、提供することもでき、また噴射剤と共に充填したエアゾールの剤型をとってもよい。

BACKGROUND OF THE INVENTION
The present invention relates to a whitening cosmetic that has an excellent skin whitening effect on spots and freckles caused by sunburn.
[0002]
[Prior art]
Conventionally, whitening cosmetics have been of great interest for improving skin color blackness, spots, freckles, etc. In these, ascorbic acid, glutathione, colloidal sulfur and the like have been incorporated as active ingredients. . There are also examples using various medicinal plant extracts, plant-derived gallic acid, geraniin and the like. Research on the whitening effect of seaweed extract has also been actively conducted, and a melanin formation inhibitory substance (JP-A-1-224308) in a cosmetic liquid mixture comprising a brown algae extract, a melanogenesis inhibitory substance extracted from seaweed (JP-A-2 -88592), cosmetics containing a hydrophilic solvent extract of brown algae as a tyrosinase inhibitory active substance (Japanese Patent Laid-Open No. 2-124810), and a hydrophilic organic solvent extract of the red alga genus Tsunomata Whitening cosmetics (JP-A-4-95013) are disclosed. In addition, whitening components such as kojic acid and arbutin which is a glucopyranoside derivative have recently been used. Such whitening components include tyrosinase activity inhibitors that inhibit the activity of tyrosinase that catalyzes the production of melanin, melanin biosynthesis inhibitors that inhibit part or all of the process of producing melanin from tyrosine via dopa, dopaquinone, dopachrome, Melanin excretion promoters and the like that normalize melanin metabolism are known.
[0003]
[Problems to be solved by the invention]
However, ascorbic acid is easily oxidized and unstable, and glutathione and colloidal sulfur have the disadvantage that they produce a characteristic odor and precipitation. In addition, conventional medicinal plant extracts and seaweed extracts have problems that their effects are insufficient and the quality is not constant. Furthermore, it has been necessary to consider the maintenance of the stability of kojic acid and the like. In addition, side effects caused side effects.
[0004]
An object of the present invention is to solve such problems and to provide a whitening cosmetic composition that is excellent in melanin production inhibitory effect and that has high safety and stability.
[0005]
[Means for Solving the Problems]
Since whitening cosmetics are used continuously every day, it is desired that the active ingredients blended with them are mild in action, exhibit sufficient effects by continuous use, and have no side effects due to continuous use. Therefore, we screened plant extracts that have an effective and mild skin-whitening effect, as well as high stability and safety.
[0006]
As a result, a high melanin production inhibitory effect was found in an extract of one or more plants selected from the genus Droseraceae and Drosera L .. These plant extracts have no adverse effects on the skin such as skin irritation and skin sensitization, and when blended with whitening cosmetics, the melanin production inhibitory effect is not inactivated and the quality is stable. It was. The plant of the genus Mosengoke is a carnivorous plant that has a large number of glandular hairs on the surface of the leaf blades and sticks out small animals by sticking out mucus, and the whole plant has been used as expectorant, detoxification, and analgesic. As the use of the extract of the plant belonging to the genus Pleurotus genus, an anti-androgenic agent containing the extract of Pleurotus genus as an active ingredient and its use for cosmetics (Japanese Patent Laid-Open No. 11-180819) have already been disclosed.

[0008]
These extracts from the genus Drosera L. are used in various raw plants or in one or more places such as leaves, bark, roots, flowers, branches, fruits, etc., raw or dried. Among them, whole plant extracts are the most effective. The extraction solvent is not particularly limited, and monohydric alcohols such as water, ethanol, methanol, isopropanol, isobutanol, n-hexanol, methyl amyl alcohol, 2-ethyl butanol, n-octyl alcohol, glycerin, ethylene glycol, ethylene Polyols such as glycol monomethyl ether, propylene glycol, propylene glycol monomethyl ether, propylene glycol monoethyl ether, triethylene glycol, 1,3-butylene glycol, hexylene glycol or derivatives thereof, acetone, methyl ethyl ketone, methyl isobutyl ketone, methyl ketones such as -n-propyl ketone, esters such as ethyl acetate and isopropyl acetate, ethers such as ethyl ether, isopropyl ether and n-butyl ether , Hydrocarbons such as squalane, petrolatum, paraffin wax, paraffin oil, olive oil, wheat germ oil, rice oil, sesame oil, macadamian nut oil, almond oil, coconut oil and other vegetable oils, beef fat, pork fat, whale oil, etc. Animal fats and oils are exemplified. In addition, polar solvents to which inorganic salts such as phosphate buffered saline are added, and solvents to which surfactants are added can be used, and although not particularly limited, safety and effects when blended into whitening cosmetics Therefore, it is preferable to use one or more solvents selected from water, ethanol, and 1,3-butylene glycol.
[0009]
Furthermore, examples of the extraction method include a method of extraction by impregnation in a cooled or heated state at room temperature, a method of extraction using a distillation method such as steam distillation, a pressing method of squeezing a genus Pleurotus and obtaining an extract. These methods are used alone or in combination of two or more.
[0010]
The ratio of the genus Mosorghum plant and the solvent at the time of extraction is not particularly limited. Is preferred. The extraction pressure and extraction temperature are conveniently in the range from 0 ° C. to the boiling point of the solvent under normal pressure, and the extraction time is preferably in the range of 2 hours to 2 weeks, although it varies depending on the extraction temperature.
[0011]
As for the extract of the genus Pleurotus genus obtained in this way, the extract can be used as it is. However, as long as the effect is not lost, purification operations such as deodorization, decolorization and concentration are added, and further, column chromatography is performed. It may be used as a fraction using a graphic or the like. These extracts, purified products, and fractions can be dried by removing the solvent from them, and can be used in a form solubilized in a solvent such as alcohol, or in the form of an emulsion. it can.
[0012]
The blending amount of these melanogaster plant extracts having an inhibitory effect on melanin production into the whitening cosmetics is set to a concentration range of 0.0001 to 10% by weight in consideration of the effect, odor and color tone when added. It is desirable.
[0013]
