Abstract
Description
【０００１】
【発明の属する技術分野】
本発明は液状油性皮膚洗浄料に関する。更に詳しくは、水で洗い流しやすく、安定性が良好な液状油性皮膚洗浄料に関する。
【０００２】
【従来の技術】
口紅、ファンデーション、マスカラ、アイシャドウ等の油分を含むメイクアップ化粧料を洗い落とすためには、油分を多く含む洗浄料を用いることが最も洗浄効果が高く、また液状の基剤であるほうが、ジェル状、クリーム状の基剤よりもメイクアップ化粧料とのなじみが良いという利点があるため、液状の油性皮膚洗浄料、すなわちクレンジングオイルと呼ばれるものがメイクアップ化粧料を落とすための洗浄料として多く使われている。
【０００３】
しかしながら、液状油性皮膚洗浄料の欠点として、油分を多く含むために水で簡単に洗い流すことができず、皮膚上に油分が多く残るため、使用後感が悪いという問題点がある。そのため、水で洗い流し易くするために、油分を乳化することのできる界面活性剤を配合することが従来から行われている（例えば特許文献１，２，３参照）。
【０００４】
【特許文献１】
特開平１１−２４６３４８号公報
【特許文献２】
特開２００２−８７９４８号公報
【特許文献３】
特開２００２−１１４６２３号公報
【０００５】
【発明が解決しようとする課題】
水で洗い流しやすくするために配合する界面活性剤としては、油分を水中油型（Ｏ／Ｗ型）に乳化しやすい界面活性剤を配合することが必要であるが、このような性質を有するＨＬＢの高い界面活性剤そのものは油分に溶解しにくいため、液状油性基剤に配合しても二層に分離したり沈殿が生成したりして安定性に問題があり、安定な液状油性皮膚洗浄料を得ることが難しいという問題があった。
【０００６】
一方、油分に溶解しやすいＨＬＢの低い界面活性剤を配合した場合には、安定性においては問題のない液状油性皮膚洗浄料を得ることができるが、このようなＨＬＢの低い界面活性剤は油分を油中水型（Ｗ／Ｏ型）に乳化するため、水で洗い流し難くなるという問題がある。
【０００７】
このため、液状油性皮膚洗浄料には上記各界面活性剤の中間的なＨＬＢ値を有するＨＬＢ＝６〜８の界面活性剤が配合される場合がほとんどであった。
【０００８】
本発明者は上述の問題点を解決するために鋭意研究を重ねた結果、高ＨＬＢ（８〜１６）の界面活性剤、中ＨＬＢ（６〜８）の界面活性剤、低ＨＬＢ（４〜６）の界面活性剤を特定の割合で組み合わせて処方中に配合することにより、水洗性に優れ、かつ安定な液状油性皮膚洗浄料が得られることを見出し、本発明を完成するに至った。
【０００９】
【課題を解決するための手段】
すなわち、本発明は、（ａ）油性成分を５０〜９５質量％と、（ｂ）脂肪酸エステル型又はアルキルエーテル型非イオン性界面活性剤を１〜３０質量％と、（ｃ）水を０．１〜５質量％とを含有する液状油性皮膚洗浄料であって、前記（ｂ）成分が、（ｂ）成分の合計量に対し、ＨＬＢ８以上、１６以下の界面活性剤を３０〜９０質量％、ＨＬＢ６以上、８未満の界面活性剤を５〜５０質量％、ＨＬＢ４以上、６未満の界面活性剤を５〜５０質量％含むものであることを特徴とする液状油性皮膚洗浄料である。
【００１０】
【発明の実施の形態】
以下、本発明の構成について詳述する。
本発明で用いる油性成分としては、通常化粧料に使用される液状油分であれば制限はなく、どのようなものでも用いることができる。
具体的には、例えば、流動パラフィン、スクワランなどの炭化水素油、２−エチルヘキサン酸セチル、トリ（２−エチルヘキサン酸）グリセリルなどの合成エステル油、ジメチルポリシロキサン、メチルフェニルポリシロキサン、デカメチルシクロペンタシロキサンなどのシリコーン油、ホホバ油、マカデミアナッツ油などの植物油などを用いることができる。
【００１１】
本発明の液状油性皮膚洗浄料においては、上記油性成分が液状油性皮膚洗浄料全量の５０〜９５質量％、好ましくは７０〜９０質量％配合される。
【００１２】
本発明に用いる（ｂ）脂肪酸エステル型又はアルキルエーテル型非イオン性界面活性剤は、該活性剤の合計に対し、ＨＬＢ８以上、１６以下の活性剤を３０〜９０質量％、ＨＬＢ６以上、８未満の活性剤を５〜５０質量％、ＨＬＢ４以上、６未満の活性剤を５〜５０質量％の割合で配合される。
【００１３】

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a liquid oily skin cleanser. More specifically, the present invention relates to a liquid oily skin cleanser that is easily washed off with water and has good stability.
[0002]
[Prior art]
In order to wash off makeup cosmetics containing oils such as lipstick, foundation, mascara, eyeshadow, etc., it is most effective to use a cleaning agent containing a large amount of oil, and the liquid base is more gel-like. Because it has the advantage that it is more compatible with makeup cosmetics than cream-like bases, liquid oily skin cleansing agents, that is, cleansing oils, are often used as cleaning agents for removing makeup cosmetics. Has been done.
[0003]
However, a disadvantage of the liquid oily skin cleanser is that it contains a large amount of oil and cannot be easily washed away with water, and a large amount of oil remains on the skin, resulting in a poor feeling after use. Therefore, in order to make it easy to wash away with water, a surfactant capable of emulsifying an oil component has been conventionally mixed (for example, see Patent Documents 1, 2, and 3).
[0004]

Japanese Patent Application Laid-Open No. 2002-87948 [Patent Document 3]
JP-A-2002-114623
[Problems to be solved by the invention]
As a surfactant to be blended to make it easy to wash out with water, it is necessary to blend a surfactant which easily emulsifies an oil component into an oil-in-water type (O / W type). Surfactants are difficult to dissolve in oils, so even when blended with a liquid oily base, there are problems with stability due to separation into two layers and formation of precipitates, and a stable liquid oily skin cleanser There was a problem that it was difficult to obtain.
[0006]
On the other hand, when a surfactant having a low HLB that easily dissolves in the oil is blended, a liquid oily skin cleanser having no problem in stability can be obtained. Is emulsified into a water-in-oil type (W / O type), so that there is a problem that it is difficult to wash away with water.
[0007]
For this reason, in most cases, the liquid oily skin cleanser is mixed with a surfactant having an HLB value of 6 to 8 having an intermediate HLB value of the above-mentioned surfactants.
[0008]
The present inventors have conducted intensive studies to solve the above-mentioned problems, and as a result, have found that high HLB (8 to 16) surfactants, medium HLB (6 to 8) surfactants, and low HLB (4 to 6) surfactants. The present inventors have found that a liquid oily skin cleanser which is excellent in water washability and stable can be obtained by combining the surfactants of the formula (1) in a specific ratio in the formulation, and has completed the present invention.
[0009]
[Means for Solving the Problems]
That is, the present invention provides (a) 50 to 95% by mass of an oily component, (b) 1 to 30% by mass of a fatty acid ester type or alkyl ether type nonionic surfactant, and (c) 0.1% of water. A liquid oily skin cleanser containing 1 to 5% by mass, wherein the component (b) contains 30 to 90% by mass of a surfactant having an HLB of 8 or more and 16 or less based on the total amount of the component (b). A liquid oily skin cleanser comprising 5 to 50% by mass of a surfactant having an HLB of 6 or more and less than 8 and 5 to 50% by mass of a surfactant having an HLB of 4 or more and less than 6.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the configuration of the present invention will be described in detail.
The oil component used in the present invention is not limited as long as it is a liquid oil component usually used in cosmetics, and any oil component can be used.
Specifically, for example, liquid paraffin, hydrocarbon oils such as squalane, synthetic ester oils such as cetyl 2-ethylhexanoate and glyceryl tri (2-ethylhexanoate), dimethylpolysiloxane, methylphenylpolysiloxane, decamethyl Silicone oil such as cyclopentasiloxane, vegetable oil such as jojoba oil, macadamia nut oil and the like can be used.
[0011]
In the liquid oily skin cleanser of the present invention, the oily component is blended in an amount of 50 to 95% by mass, preferably 70 to 90% by mass of the total amount of the liquid oily skin cleanser.
[0012]
The (b) fatty acid ester type or alkyl ether type nonionic surfactant used in the present invention comprises 30 to 90% by mass of an activator having an HLB of 8 or more and 16 or less, and an HLB of 6 or more and less than 8, based on the total of the activators. 5 to 50% by mass of an activator, and 5 to 50% by mass of an activator having an HLB of 4 or more and less than 6.
[0013]
When a nonionic surfactant having an HLB lower than 4 is used, the oil component is easily emulsified in a W / O type, and the oil cannot be easily washed off, which is not preferable. When a nonionic surfactant having an HLB higher than 16 is used, the solubility in oil is very low, and it is difficult to obtain a stable liquid preparation, and in any case, a satisfactory result cannot be obtained. In the present invention, it is necessary to use the above three types of nonionic surfactants in specific amounts.
[0014]
The fatty acid ester type or alkyl ether type nonionic surfactant having an HLB of 8 or more and 16 or less includes, for example, POE (5) nonylphenyl ether (HLB = 8), POE (10) decyl pentadecyl ether (HLB = 8), POE (6) monoisostearate (HLB = 8), POE (6) monooleate (HLB = 8), POE (5) octylphenyl ether (HLB = 9), POE (5) lauryl ether (HLB = 9), POE (10) behenyl ether (HLB = 9), POE (10) decyltetradecyl ether (HLB = 9), POE (10) cholesteryl ether (HLB = 9), POE (8) glyceryl monoisostearate (HLB = 9), sorbitan monoisostearate (HLB = 9), POE (10) oley Ether (HLB = 10), POE (10) octyldodecyl ether (HLB = 10), POE (30) glyceryl triisostearate (HLB = 10), decaglyceryl diisostearate (HLB = 10), POE (10) mono Isostearate (HLB = 11), POE (10) monooleate (HLB = 11), POE (15) Isostearyl ether (HLB = 12), POE (20) Oleyl ether (POE = 14), POE (20) mono And sorbitan oleate (HLB = 15).

If the blending amount of the fatty acid ester type or alkyl ether type nonionic surfactant having an HLB of 8 or more and 16 or less is too small, it is difficult to obtain easy rinsing, and if it is too large, the transparency of the system is impaired.
[0016]
Examples of the fatty acid ester type or alkyl ether type nonionic surfactant having an HLB of 6 or more and less than 8 include POE (5) oleyl ether (HLB = 6), POE (10) hydrogenated castor oil (HLB = 6), and POE ( 30) hydrogenated castor oil triisostearate (HLB = 6), diglyceryl monostearate (HLB = 6), POE (5) cetyl ether (HLB = 7), POE (6) stearyl ether (HLB = 7), POE (5) hexyldecyl ether (POE = 7), POE (5) isostearyl ether (HLB = 7), POE (8) dilaurate (HLB = 7), POE (5) monostearate (HLB = 7), POE (12) diisostearate (HLB = 7), POE (12) dioleate (HLB = 7), POE (20) Seryl triisostearate (HLB = 7), POE (20) glyceryl trioleate (HLB = 7), POE (20) hydrogenated castor oil monoisostearate (HLB = 7), POE (40) sorbitan tetraoleate ( HLB = 7) and the like, and in particular, POE (12) diisostearate (HLB = 7), POE (12) dioleate (HLB = 7), POE (20) glyceryl triisostearate (HLB = 7), POE (40) sorbitan tetraoleate (HLB = 7) is preferred.
[0017]
The compounding amount of the fatty acid ester type or alkyl ether type nonionic surfactant having an HLB of 6 or more and less than 8 is 5 to 50% by mass, preferably 5 to 30% by mass based on the total amount of the component (b). If the amount of the fatty acid ester type or alkyl ether type nonionic surfactant having an HLB of 6 or more and less than 8 is too small, the transparency of the system is impaired, and if it is too large, precipitation occurs at a low temperature.
[0018]
Examples of the fatty acid ester type or alkyl ether type nonionic surfactant having an HLB of 4 or more and less than 6 include POE (8) diisostearate (HLB = 5), POE (8) dioleate (HLB = 5), and POE ( 3) Glyceryl monoisostearate (HLB = 5), glyceryl monoisostearate (HLB = 5) and the like, particularly POE (8) diisostearate (HLB = 5), POE (8) dioleate (HLB = 5) is preferred.
[0019]
The compounding amount of the fatty acid ester type or alkyl ether type nonionic surfactant having an HLB of 4 or more and less than 6 is 5 to 50% by mass, preferably 5 to 30% by mass based on the total amount of the component (b). If the blending amount of the fatty acid ester type or alkyl ether type nonionic surfactant having an HLB of 4 or more and less than 6 is too small, the separation of the system occurs at a high temperature, and if it is too large, it is difficult to obtain easy rinsing.
[0020]
In the present invention, the total amount of the above nonionic surfactant is 1 to 30% by mass, preferably 5 to 15% by mass, based on the total amount of the liquid oily skin cleanser. When the amount is less than 1% by mass, sufficient ease of washing with water cannot be obtained. When the amount exceeds 30% by mass, stability problems such as precipitation and separation occur, and both are satisfactory. No result is obtained.
[0021]
The amount of water used in the present invention is 0.1 to 5% by mass, preferably 1.0 to 3.5% by mass, based on the total amount of the skin cleanser. If the amount of water is less than 0.1% by mass, turbidity / precipitation occurs and the stability is deteriorated. If the amount is more than 5% by mass, a uniform system is hardly formed and the stability is deteriorated.
[0022]
In the liquid oily skin cleanser according to the present invention, in addition to the above essential constituents, if necessary, a component which is generally blended in a cleanser, a cosmetic, etc., within a range not impairing the effects of the present invention. can do.
