Description
本発明は、メイクアップ化粧料用クレンジング料に関し、更に詳細には、特定のゾル−ゲル転移温度を有する高分子化合物の水溶液を含有し、べたつきのない良好な使用感と優れたクレンジング力を有するメイクアップ化粧料用クレンジング料に関する。 The present invention relates to a cleansing material for makeup cosmetics, and more specifically, contains an aqueous solution of a polymer compound having a specific sol-gel transition temperature, and has a good feeling without stickiness and an excellent cleansing power. The present invention relates to a cleansing material for makeup cosmetics.
クレンジング料は、皮脂由来の汚れやメイクアップ化粧料を除去するために用いられる化粧料であり、クレンジングクリーム、クレンジングローション、クレンジングジェル、クレンジングオイルと多種の剤型が存在する Cleansing agents are cosmetics used to remove sebum-derived stains and makeup cosmetics, and there are various types of formulations such as cleansing creams, cleansing lotions, cleansing gels, and cleansing oils.
最近のメイクアップ化粧料は化粧崩れをしにくいように設計されており、落ちにくい製品が多くなっているが、このような背景から、それを落とすためのクレンジング料にも様々な工夫がなされている(特許文献1〜4)。 Recent makeup cosmetics are designed to make it difficult to break down makeup, and there are many products that are hard to fall off. Against this background, various ingenuity has been made in cleansing fees to remove it. (Patent Documents 1 to 4).
特に油性成分を含有するメイクアップ化粧料を落とすためには、皮脂やメイクアップ化粧料等の油性汚れへの馴染みを考え、油剤を主成分とするオイルクレンジングが汎用されている。しかしこれは、使用中および使用後の油感やべたつき等があり、使用感が悪いという問題があった。また、クレンジングクリームは、油性成分だけでなく水性成分も含むため、使用中および使用後の油感やべたつきはクレンジングオイルほど感じないものクレンジング力がクレンジングオイルより劣るという問題があった。 In particular, in order to remove makeup cosmetics containing oily components, oil cleansings mainly composed of oils are widely used in consideration of familiarity with oily soils such as sebum and makeup cosmetics. However, this has a problem that the oily feeling and stickiness during use and after use are bad and the feeling of use is poor. Moreover, since the cleansing cream contains not only an oily component but also an aqueous component, there is a problem that the cleansing power is inferior to the cleansing oil although the oily feeling and stickiness during use and after use are not felt as the cleansing oil.
従って、本発明は、クレンジング力や使用感がよく、しかも、使用後の油感やべたつきがないメイクアップ化粧料用クレンジング料を提供することを課題とするものである。 Therefore, an object of the present invention is to provide a cleansing material for makeup cosmetics that has good cleansing power and feeling of use, and that does not have oily feeling or stickiness after use.
本発明者らは上記課題を解決するために鋭意研究した結果、特定のゾル−ゲル転移温度を有する高分子化合物の水溶液をメイクアップ化粧料用クレンジング料に含有させることにより、上記課題を解決できることを見出し、本発明を完成させた。 As a result of intensive studies to solve the above problems, the present inventors can solve the above problems by including an aqueous solution of a polymer compound having a specific sol-gel transition temperature in a cleansing material for makeup cosmetics. The present invention was completed.
すなわち、本発明は、0℃より高く37℃より低い下限臨界溶液温度(LCST)を有する複数の高分子部分と親水性高分子部分が結合したブロック共重合体またはグラフト共重合体であって、その水溶液が0℃より高く37℃より低い温度にゾル−ゲル転移温度を有する高分子化合物と、水とを含有することを特徴とするメイクアップ化粧料用クレンジング料である。 That is, the present invention is a block copolymer or graft copolymer in which a plurality of polymer parts having a lower critical solution temperature (LCST) higher than 0 ° C. and lower than 37 ° C. and a hydrophilic polymer part are combined, A cleansing material for makeup cosmetics, characterized in that the aqueous solution contains a polymer compound having a sol-gel transition temperature at a temperature higher than 0 ° C. and lower than 37 ° C. and water.
本発明のメイクアップ化粧料用クレンジング料は、これに含まれる特定のゾル−ゲル転移温度を有する高分子化合物の水溶液が、使用時に落したいメイクアップ化粧料と馴染ませるマッサージ(クレンジング)動作の過程で、肌上において体温でゲル化し、メイクアップ化粧料を内包しながら弾力感のある塊ないしは構造性を有するペースト状態になって肌から除去されるため、肌への摩擦刺激や抵抗も少なく、優れたクレンジング力を有するものとなる。 The cleansing material for makeup cosmetics of the present invention is a process of a massage (cleansing) operation in which an aqueous solution of a polymer compound having a specific sol-gel transition temperature contained therein is adapted to the makeup cosmetic that is desired to be removed during use. Because it is gelled at body temperature on the skin, and it is removed from the skin in the form of a paste with elasticity or structure while containing makeup cosmetics, there is little friction stimulation and resistance to the skin, It has excellent cleansing power.
また、本発明のメイクアップ化粧料用クレンジング料は、クレンジング効果を発現するために、メイクアップ化粧料に含有される油性成分との馴染み(相溶性)を考えて通常のクレンジング料には配合される油剤を実質的に配合する必要がないため、使用中およびクレンジング後の油感やべたつきのない、さっぱりとした使用感を有するという優れたものである。 In addition, the cleansing composition for makeup cosmetics of the present invention is blended in a normal cleansing composition in consideration of the familiarity (compatibility) with the oil component contained in the makeup cosmetics in order to express the cleansing effect. Therefore, it is excellent in that it has a refreshing feeling of use without oiliness and stickiness during use and after cleansing.
本明細書において、下限臨界溶液温度(LCST;Lower Critical Solution Temperature)とは、この温度よりも低い温度では高分子が水に溶解して透明の溶液となるが、この温度よりも高い温度では不溶化して白濁するか沈殿が生じ、相分離する温度である。 In this specification, the lower critical solution temperature (LCST) means that a polymer is dissolved in water at a temperature lower than this temperature and becomes a transparent solution, but becomes insoluble at a temperature higher than this temperature. The temperature at which the solution becomes cloudy or precipitates and the phases are separated.
本発明のメイクアップ化粧料用クレンジング料(以下、「本発明のクレンジング料」という)は、0℃より高く37℃より低いLCSTを有する複数の高分子部分と親水性高分子部分が結合したブロック共重合体またはグラフト共重合体であって、その水溶液が0℃より高く37℃より低い温度にゾル−ゲル転移温度を有する高分子化合物(以下、「温度応答性高分子化合物」という)と、水とを必須成分とするものである。 The cleansing material for makeup cosmetics of the present invention (hereinafter referred to as “the cleansing material of the present invention”) is a block in which a plurality of polymer parts having an LCST higher than 0 ° C. and lower than 37 ° C. are combined with a hydrophilic polymer part A polymer or graft copolymer, the polymer solution of which an aqueous solution has a sol-gel transition temperature at a temperature higher than 0 ° C. and lower than 37 ° C.

At temperature, it loses fluidity and gels. Such a temperature-responsive polymer compound is a known compound, and for example, is described as a polymer compound having a sol-gel transition temperature in Japanese Patent No. 3585309. The temperature-responsive polymer compound can also be produced in accordance with Examples 1 to 6 of this Japanese Patent No. 3585309 and other descriptions.
上記温度応答性高分子化合物は、複数の0℃より高く37℃より低いLCSTを有する高分子部分(以下、「LCST高分子部分」ということがある)を含むものである。このLCST高分子部分には、LCST挙動を示す温度応答性高分子が含まれる。このLCST挙動を示す温度応答性高分子としては、ポリN−置換アクリルアミド誘導体、ポリN−置換メタクリルアミド誘導体及びこれらの共重合体、ポリプロピレンオキサイド、プロピレンオキサイドと他のアルキレンオキサイドとの共重合体、ポリビニルメチルエーテル、ポリビニルアルコール部分酢化物、ポリアルキレンオキサイド等が挙げられる。より具体的には、ポリ−N−アクリロイルピペリジン、ポリ−N−n−プロピルメタアクリルアミド、ポリ−N−イソプロピルアクリルアミド、ポリ−N,N−ジエチルアクリルアミド、ポリ−N−イソプロピルメタアクリルアミド、ポリ−N−シクロプロピルアクリルアミド、ポリ−N−アクリロイルピロリジン、ポリ−N,N−エチルメチルアクリルアミド、ポリ−N−シクロプロピルメタアクリルアミド、ポリ−N−エチルアクリルアミドなどが挙げられ、特にポリ−N−イソプロピルアクリルアミドが好ましく用いられる。 The temperature-responsive polymer compound includes a plurality of polymer portions having an LCST higher than 0 ° C. and lower than 37 ° C. (hereinafter sometimes referred to as “LCST polymer portion”). The LCST polymer portion includes a temperature-responsive polymer that exhibits LCST behavior. Examples of the temperature-responsive polymer exhibiting this LCST behavior include poly N-substituted acrylamide derivatives, poly N-substituted methacrylamide derivatives and copolymers thereof, polypropylene oxide, copolymers of propylene oxide and other alkylene oxides, Examples thereof include polyvinyl methyl ether, polyvinyl alcohol partially acetylated product, and polyalkylene oxide. More specifically, poly-N-acryloylpiperidine, poly-Nn-propylmethacrylamide, poly-N-isopropylacrylamide, poly-N, N-diethylacrylamide, poly-N-isopropylmethacrylamide, poly-N -Cyclopropylacrylamide, poly-N-acryloylpyrrolidine, poly-N, N-ethylmethylacrylamide, poly-N-cyclopropylmethacrylamide, poly-N-ethylacrylamide, etc., and especially poly-N-isopropylacrylamide Preferably used.
上記LCST高分子部分は、前記LCSTを有する高分子のみから構成されるホモポリマーであってもよいが、さらに他のモノマーと共重合させたコポリマーであってもよい。このようなコポリマーを構成する他のモノマーとして、親水性モノマー及び疎水性モノマーのいずれも用いることができる。 The LCST polymer portion may be a homopolymer composed only of the polymer having LCST, or may be a copolymer copolymerized with another monomer. As other monomers constituting such a copolymer, both hydrophilic monomers and hydrophobic monomers can be used.
上記親水性モノマーとしては、N−ビニルピロリドン、ビニルピリジン、アクリルアミド、メタアクリルアミド、N−メチルアクリルアミド、ヒドリキシエチルメタアクリレート、ヒドロキシエチルアクリレート、ヒドロキシメチルメタアクリレート、ヒドロキシメチルアクリレート、酸性基を有するアクリル酸、メタアクリル酸及びそれらの塩、ビニルスルホン酸、スチレンスルホン酸等、並びに塩基性基を有するN,N−ジメチルアミノエチルメタクリレート、N,N−ジエチルアミノエチルメタクリレート、N,N−ジメチルアミノプロピルアクリルアミド及びそれらの塩等が例示できる。 Examples of the hydrophilic monomer include N-vinylpyrrolidone, vinylpyridine, acrylamide, methacrylamide, N-methylacrylamide, hydroxyethyl methacrylate, hydroxyethyl acrylate, hydroxymethyl methacrylate, hydroxymethyl acrylate, and acrylic acid having an acidic group.

上記温度応答性高分子化合物を構成する上記LCST高分子部分は、LCSTが0℃よりも高く37℃よりも低い範囲にあるものである。このLCST高分子部分をホモポリマーとする場合は、例えばポリ−N−イソプロピルアクリルアミドやポリ−N−n−プロピルメタアクリルアミドなど、固有のLCST温度が0〜37℃の範囲にあるものを適宜選択することができる。一方、LCST高分子部分をコポリマーとする場合には、一般的にLCSTを有する高分子に親水性モノマーを共重合することにより、コポリマーのLCSTを上昇させることが可能となり、また疎水性モノマーを共重合することにより、LCSTを下降させることが可能となるため、LCST挙動を示す温度応答性高分子と共重合させるモノマーの組み合わせを選択し、組成比等を調整することによって、0〜37℃の範囲で高分子部分のLCSTを調整することができる。 The LCST polymer portion constituting the temperature-responsive polymer compound has an LCST in a range higher than 0 ° C. and lower than 37 ° C. When the LCST polymer portion is a homopolymer, a polymer having an inherent LCST temperature in the range of 0 to 37 ° C. such as poly-N-isopropylacrylamide or poly-Nn-propylmethacrylamide is appropriately selected. be able to. On the other hand, when the LCST polymer portion is a copolymer, it is generally possible to increase the LCST of the copolymer by copolymerizing a hydrophilic monomer with a polymer having LCST, and to co-polymerize a hydrophobic monomer. Since the LCST can be lowered by polymerization, a combination of monomers to be copolymerized with a temperature-responsive polymer exhibiting LCST behavior is selected, and the composition ratio and the like are adjusted to 0 to 37 ° C. The LCST of the polymer portion can be adjusted within the range.
また、温度応答性高分子化合物は、上記LCST高分子部分の他に、親水性高分子部分を含有するものである。この親水性高分子部分を構成する高分子としては、例えば、メチルセルロース、デキストラン、ポリエチレンオキサイド、ポリプロピレンオキサイド等のポリアルキレンオキサイド、ポリビニルアルコール、ポリN−ビニルピロリドン、ポリビニルピリジン、ポリアクリルアミド、ポリメタアクリルアミド、ポリN−メチルアクリルアミド、ポリヒドロキシメチルアクリレート、ポリアクリル酸、ポリメタクリル酸、ポリビニルスルホン酸、ポリスチレンスルホン酸およびそれらの塩、ポリN,N−ジメチルアミノエチルメタクリレート、ポリN,N−ジエチルアミノエチルメタクリレート、ポリN,N−ジメチルアミノプロピルアクリルアミドおよびそれらの塩等が挙げられる。 The temperature-responsive polymer compound contains a hydrophilic polymer portion in addition to the LCST polymer portion.

更に、温度応答性高分子化合物は、上記LCST高分子部分と親水性高分子部分が結合したブロック共重合体またはグラフト重合体である。グラフト重合体の場合は、LCST高分子部分が主鎖で親水性高分子部分が側鎖として結合したものであっても、主鎖が親水性高分子部分で、側鎖としてLCST高分子部分が結合したものであってもよい。 Furthermore, the temperature-responsive polymer compound is a block copolymer or graft polymer in which the LCST polymer part and the hydrophilic polymer part are bonded. In the case of a graft polymer, even if the LCST polymer part is a main chain and the hydrophilic polymer part is bonded as a side chain, the main chain is a hydrophilic polymer part and the LCST polymer part is a side chain. It may be combined.
上記LCST高分子部分と、親水性高分子部分とのブロック共重合体は、例えば予め両者に反応活性な官能基(水酸基、カルボキシル基、アミノ基、イソシアネート基等)を複数導入し、両者を化学反応により結合させることによって得ることができる。例えば、親水性高分子であるポリエチレンオキサイドの両末端に重合性官能基であるメタクリロイル基を導入し、LCSTを有する高分子を構成するモノマーであるN−イソプロピルアクリルアミドと共重合させることによって、ポリ−N−イソプロピルアクリルアミドから構成されるLCST高分子部分とポリエチレンオキサイドからなる親水性高分子部分とのブロック共重合体を得ることができる。 The block copolymer of the above-mentioned LCST polymer part and hydrophilic polymer part, for example, introduces a plurality of reactive functional groups (hydroxyl group, carboxyl group, amino group, isocyanate group, etc.) in advance and chemistry of both. It can be obtained by bonding by reaction. For example, by introducing a methacryloyl group which is a polymerizable functional group into both ends of polyethylene oxide which is a hydrophilic polymer, and copolymerizing with N-isopropylacrylamide which is a monomer constituting a polymer having LCST, poly- A block copolymer of an LCST polymer portion composed of N-isopropylacrylamide and a hydrophilic polymer portion composed of polyethylene oxide can be obtained.
また、N−イソプロピルアクリルアミドとN−アクリロキシスクシンイミドを共重合させて1級アミンと反応する基を導入した高分子を合成し、これと末端に1級アミノ基を導入したポリエチレンオキサイドを反応させることによって、ポリ−N−イソプロピルアクリルアミドから構成されるLCST高分子部分とポリエチレンオキサイドからなる親水性高分子部分とのブロック共重合体を得ることができる。 Also, N-isopropylacrylamide and N-acryloxy succinimide are copolymerized to synthesize a polymer in which a group capable of reacting with a primary amine is introduced, and this is reacted with polyethylene oxide having a primary amino group introduced at the terminal. Thus, a block copolymer of an LCST polymer portion composed of poly-N-isopropylacrylamide and a hydrophilic polymer portion composed of polyethylene oxide can be obtained.
また、上記LCSTを有する高分子部分と親水性高分子部分とのグラフト共重合体は、通常のグラフト重合法を用いることができ、重合体の連鎖移動反応を利用する方法、幹重合体に遊離基に***し得る官能基を導入し、該官能基から重合を開始する方法、幹重合体からイオン重合を開始せしめる方法等を用いることができるが、側鎖の重合度を制御するという観点からは、LCST高分子部分中に1個の重合性官能基を導入し、親水性高分子部分を与えるモノマーと共重合させる方法や、親水性高分子部分中に1個の重合性官能基を導入し、LCST高分子部分を構成するモノマーと共重合させる方法などが好ましく用いられる。 In addition, the graft copolymer of the polymer part having LCST and the hydrophilic polymer part can use a normal graft polymerization method, a method using a chain transfer reaction of the polymer, and free to the backbone polymer. From the viewpoint of controlling the degree of polymerization of the side chain, it is possible to use a method of introducing a functional group capable of splitting into a group and starting polymerization from the functional group, a method of starting ionic polymerization from a trunk polymer, etc. Introducing one polymerizable functional group into the LCST polymer part and copolymerizing with a monomer that gives the hydrophilic polymer part, or introducing one polymerizable functional group into the hydrophilic polymer part A method of copolymerizing with a monomer constituting the LCST polymer portion is preferably used.
上記温度応答性高分子化合物の分子量は、特に制限されないが、1万以上が好ましく、特に10万以上がゾル−ゲル転移温度より高い温度では良好にゲルが形成されるので好ましい。この温度応答性高分子化合物の分子量の測定は、前記特許第3585309号公報に記載の方法に従って行うことができる。 The molecular weight of the temperature-responsive polymer compound is not particularly limited, but is preferably 10,000 or more, and particularly preferably 100,000 or more because a gel is favorably formed at a temperature higher than the sol-gel transition temperature. The molecular weight of the temperature-responsive polymer compound can be measured according to the method described in Japanese Patent No. 3585309.
以上のようにして、LCST高分子部分と親水性高分子部分の組成や、両高分子部分の疎水度および親水度、分子量等によって、温度応答性高分子化合物の水溶液のゾルーゲル転移温度を、0℃より高く37℃より低い温度のものに調製することができる。 As described above, the sol-gel transition temperature of the aqueous solution of the temperature-responsive polymer compound is set to 0 depending on the composition of the LCST polymer part and the hydrophilic polymer part, the hydrophobicity and hydrophilicity of both polymer parts, the molecular weight, and the like. It can be prepared to have a temperature higher than 37 ° C. and lower than 37 ° C.
