【発明の属する技術分野】
本発明はオイル状クレンジング化粧料に関する。さらに詳しくは、さっぱり感に優れ、さらにクレンジング効果、洗い流しやすさ、塗布のし易さ、保存安定性に優れたオイル状クレンジング化粧料に関する。
【0002】
【従来の技術】
オイル状液体クレンジング化粧料は、基剤の大半が油分であるため、使用感が油っぽくなり、洗浄力が極めて高く安全な洗顔料であるにも拘わらず、好んで使用する人が多くはないという現状がある。
【0003】
【発明が解決しようとする課題】
これに対して、さっぱりした使用感を発揮させるため、粘性の低い油分を中心に配合するとクレンジング化粧料自体の粘性も低くなり、手の平にとり顔に塗布する際に指の間や手の平から容易にこぼれ落ち、その取り扱いに不都合な面があった。
【0004】
本発明は上記課題に鑑みてなされたものであり、油っぽくなくさっぱりした使用感を有し、粘性の低い油分を使用する必要がないため指からのたれ落ちを抑え塗布しやすく、かつ、クレンジング効果、洗浄後の洗い流しやすさ、保存安定性に優れたオイル状クレンジング化粧料を提供するものである。
【0005】
【課題を解決するための手段】
本発明は下記の通りである。
ジ分岐脂肪酸ポリエチレングリコールと油分と水とを含有し、ジ分岐脂肪酸ポリエチレングリコールの含有量が7〜30質量%であり、油分の含有量が58.5〜89.9質量%であり、水の含有量が2.1〜10質量%であり、さらにラウリン酸、オレイン酸、イソステアリン酸、若しくはこれらの塩を含有し、ラウリン酸、オレイン酸、イソステアリン酸、若しくはこれらの塩の含有量が0.5〜1.5質量%であるオイル状クレンジング化粧料であって、前記ジ分岐脂肪酸ポリエチレングリコールがPOE(8)ジイソステアレート及びPOE(12)ジイソステアレートであることを特徴とするオイル状クレンジング化粧料。
【0006】
【発明の実施の形態】
以下、本発明を詳述する。
【0007】
本発明のオイル状クレンジング化粧料は、室温(20℃)で液状の油を含む油性成分と、非イオン性界面活性剤と、水とを少なくとも含むもので、室温(25℃)で液状を呈している油状液体クレンジング化粧料である。
【0008】
従来、上記のオイル状クレンジング化粧料において、水を2重量%まで配合したものが存在するが(特許第2977568号公報)、使用時にさっぱり感を発揮する効果は極めて低い。
【0009】
本発明は、多くの処方について鋭意研究した結果、非イオン界面活性剤にジ分岐脂肪酸ポリエチレングリコールを使用すると、驚くべきことに処方中の水を従来の常識より多量に安定配合することが可能となり、優れたさっぱり感を発揮させることができると同時に、さっぱり感を確保するために粘性の低い油分を使用する必要がないため適度な粘性を有し塗布しやすく、かつ、洗浄後も洗い流しやすく、クレンジング効果も落ちることがないという当業者にして予測不可能な効果を見出した結果完成された発明である。
【0010】
さらに、ラウリン酸、オレイン酸、イソステアリン酸、あるいはこれらの塩を配合すると、驚くべきことに透明を維持できる低温領域を広げることが可能となり、低温にて保存されても外観の透明性を維持できる好ましいオイル状クレンジング化粧料を提供可能となる。
【0011】
本発明に用いるジ分岐脂肪酸ポリエチレングリコールは、POE(8)ジイソステアレート及びPOE(12)ジイソステアレートである。
【0012】
分岐脂肪酸ポリエチレングリコールの配合量は7〜30質量%が好ましく、さらに好ましくは8〜28質量%である。30質量%を超えると白濁若しくはゲル状になる場合がある。
【0013】
本発明においては、分岐脂肪酸ポリエチレングリコール以外の界面活性剤の併用も可能である。この場合、界面活性剤全量に対して分岐脂肪酸ポリエチレングリコールが50質量%を超えることが好ましい。また、界面活性剤全体としてのHLBも9を超えないように選定される。
【0014】
本発明に用いる油分は、例えば、流動パラフィン、合成パラフィン、スクワラン、イソプロピルミリステート、オクタン酸セチル、植物油(オリーブ油等)、高級アルコール(イソステアリルアルコール)、シリコーン油(ジメチコーン等)を挙げることができる。好ましい油分は、流動パラフィン、オクタン酸セチルである。
【0015】
油分の配合量は、好ましくは58.5〜89.9質量%である。
【0016】
本発明に用いる水は、水道水、イオン交換水、蒸留水、ミネラル水、深層水、海水、温泉水等を用いることができる。
【0017】
水の配合量は2.1〜10質量%が好ましく、さらに好ましくは、2.1〜8質量%である。2.1質量%未満であるとさっぱり感に乏しい。
【0018】
本発明においては、ラウリン酸、オレイン酸、イソステアリン酸、あるいはこれらの塩(例えば、ナトリウム塩、カリウム塩など)を配合すると、低温領域でさらに好ましい透明な外観が得られる。配合量は特に限定されないが0.5〜1.5質量%程度でよい。
【0019】
本発明のオイル状クレンジング化粧料は、上記必須成分の分岐脂肪酸ポリエチレングリコールと油分と水とを攪拌して調製することができるが、化粧料に配合可能な成分を本発明の効果を損なわない範囲内にて配合することが出来る。

BACKGROUND OF THE INVENTION
The present invention relates to an oily cleansing cosmetic. More specifically, the present invention relates to an oily cleansing cosmetic that is excellent in refreshing feeling, and further has a cleansing effect, ease of washing, ease of application, and storage stability.
[0002]
[Prior art]
Oily liquid cleansing cosmetics are mostly oily, so many people prefer to use them even though they are oily and have a very cleansing power and a clean face. There is no current situation.
[0003]
[Problems to be solved by the invention]
On the other hand, cleansing cosmetics itself has a lower viscosity when formulated with a low-viscosity oil to provide a refreshing feeling of use, and easily spills from between fingers and palms when applied to the palm. , There was an inconvenience in its handling.
[0004]
The present invention has been made in view of the above problems, has an oily and refreshing feeling of use, and since it is not necessary to use a low viscosity oil, it is easy to apply and suppress dripping from the finger, and The present invention provides an oil-type cleansing cosmetic excellent in cleansing effect, ease of washing after washing, and storage stability.
[0005]
[Means for Solving the Problems]
The present invention is as follows.
It contains di-branched fatty acid polyethylene glycol, oil and water, the content of di-branched fatty acid polyethylene glycol is 7 to 30% by mass, the content of oil is 58.5 to 89.9% by mass, The content is 2.1 to 10% by mass, and further contains lauric acid, oleic acid, isostearic acid, or a salt thereof, and the content of lauric acid, oleic acid, isostearic acid, or a salt thereof is 0.00. 5 to 1.5% by mass of an oily cleansing cosmetic, characterized in that the dibranched fatty acid polyethylene glycol is POE (8) diisostearate and POE (12) diisostearate Cleansing cosmetic.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
The present invention is described in detail below.
[0007]
The oily cleansing cosmetic of the present invention comprises at least an oily component containing oil that is liquid at room temperature (20 ° C), a nonionic surfactant, and water, and is liquid at room temperature (25 ° C). It is an oily liquid cleansing cosmetic.
[0008]
Conventionally, in the above oil-type cleansing cosmetics, there are those containing up to 2% by weight of water (Japanese Patent No. 2977568), but the effect of providing a refreshing feeling when used is extremely low.
[0009]
As a result of diligent research on many formulations, the present invention, when using di-branched fatty acid polyethylene glycol as a nonionic surfactant, surprisingly makes it possible to stably mix a larger amount of water in the formulation than conventional common sense. It is possible to exert an excellent refreshing feeling, and at the same time, it is not necessary to use a low viscosity oil to secure a refreshing feeling, so it has an appropriate viscosity and is easy to apply and easy to wash off after washing. The present invention has been completed as a result of finding an effect unforeseeable by those skilled in the art that the cleansing effect does not drop.
[0010]
Furthermore, when lauric acid, oleic acid, isostearic acid, or a salt thereof is added, it is surprisingly possible to expand the low-temperature region where transparency can be maintained, and transparency of appearance can be maintained even when stored at low temperatures. A preferred oily cleansing cosmetic can be provided.
[0011]
The dibranched fatty acid polyethylene glycol used in the present invention is POE (8) diisostearate and POE (12) diisostearate .
[0012]
The blending amount of the branched fatty acid polyethylene glycol is preferably 7 to 30% by mass, more preferably 8 to 28% by mass. If it exceeds 30% by mass, it may become cloudy or gelled.
[0013]
In the present invention, a surfactant other than the branched fatty acid polyethylene glycol can be used in combination. In this case, it is preferable that the branched fatty acid polyethylene glycol exceeds 50% by mass with respect to the total amount of the surfactant. Further, the HLB as the whole surfactant is selected so as not to exceed 9.
[0014]
Examples of the oil used in the present invention include liquid paraffin, synthetic paraffin, squalane, isopropyl myristate, cetyl octoate, vegetable oil (such as olive oil), higher alcohol (isostearyl alcohol), and silicone oil (such as dimethicone). . Preferred oils are liquid paraffin and cetyl octoate.
[0015]
The blending amount of the oil is preferably 58.5 to 89.9% by mass.
[0016]
As water used in the present invention, tap water, ion exchange water, distilled water, mineral water, deep water, sea water, hot spring water, and the like can be used.
[0017]
The blending amount of water is preferably 2.1 to 10% by mass, and more preferably 2.1 to 8% by mass. When it is less than 2.1% by mass, the refreshing feeling is poor.
[0018]
In the present invention, when lauric acid, oleic acid, isostearic acid, or a salt thereof (for example, sodium salt, potassium salt, etc.) is blended, a more preferable transparent appearance can be obtained in a low temperature region. The blending amount is not particularly limited, but may be about 0.5 to 1.5% by mass.
[0019]
The oily cleansing cosmetic of the present invention can be prepared by stirring the above-mentioned essential branched fatty acid polyethylene glycol, oil and water, but the components that can be blended in the cosmetic do not impair the effects of the present invention. Can be blended inside.
[0020]
The present invention is a cosmetic mainly intended for face washing, but can also be preferably used as a massage cosmetic.
[0021]
