Abstract

It is intended to provide a base for a cosmetic comprising a nonionic resin, which is soluble in water, alcohol and liquefied petroleum gas (LPG), facilitates the adjustment of a property as a base for a cosmetic, and is useful particularly as a base for a hair cosmetic. The base for a cosmetic according to the invention is a nonionic resin composed of a polymer of an ethylenic unsaturated monomer component (A) including a nonionic unsaturated monomer (a). In the nonionic unsaturated monomer (a), N,N-dimethylacrylamide (a1) represented by the following chemical formula (1) is included as an essential component. This base for a cosmetic isa nonionic resin, therefore, a problem of lack of compatibility even if it is used with another resin is unlikely to occur. Further, it shows a favorable solubility in various types of solvents for the base. The solubility of the base for a cosmetic in various types of solvents, properties as the base for a cosmetic such as a glass transition point or adhesiveness are easily adjusted.

　このうち、ノニオン性樹脂は、アニオン性樹脂、カチオン性樹脂及び両性樹脂と併用しても相溶性不足の問題が生じず、汎用性が高いという利点がある。 Of these, nonionic resins have the advantage of high versatility without the problem of insufficient compatibility even when used in combination with anionic resins, cationic resins and amphoteric resins.
　化粧料用基剤として用いられるノニオン性樹脂の具体例としては、ポリビニルアルコール、ポリビニルピロリドン、ビニルピロリドン－酢酸ビニル共重合体、ビニルピロリドン－酢酸ビニル－プロピオン酸ビニル共重合体、ビニルピロリドン－酢酸ビニル－アクリルアミノアクリレート共重合体、酢酸ビニル／Ｎ－ビニル－５－メチル－２－オキサゾリン共重合体、ヒドロキシエチルセルロース、ヒドロキシプロピルセルロース、ヒドロキシプロピルメチルセルロース、メチルセルロース、カルボキシメチルセルロース、カルボキシビニルポリマー、ポリビニルホルムアミド、ポリビニルアセトアミド等が挙げられる。 Specific examples of nonionic resins used as cosmetic bases include polyvinyl alcohol, polyvinyl pyrrolidone, vinyl pyrrolidone-vinyl acetate copolymer, vinyl pyrrolidone-vinyl acetate-vinyl propionate copolymer, vinyl pyrrolidone-vinyl acetate. -Acrylic aminoacrylate copolymer, vinyl acetate / N-vinyl-5-methyl-2-oxazoline copolymer, hydroxyethylcellulose, hydroxypropylcellulose, hydroxypropylmethylcellulose, methylcellulose, carboxymethylcellulose, carboxyvinyl polymer, polyvinylformamide, polyvinyl Examples include acetamide.
　これらのノニオン性樹脂は、水、アルコール、或いはプロパン、ブタン及びイソブタンを主成分とする液化石油ガス（ＬＰＧ）などの溶媒に溶解され、或いは更にこの毛髪化粧料用基剤が他の樹脂（アニオン性樹脂、カチオン性樹脂、ノニオン性樹脂、両性樹脂等）や、その他の添加物と混合されることで、ヘアスプレー剤、ヘアムース、ヘアセットローション、ヘアジェル等の種々の態様の毛髪化粧料に調製される。 These nonionic resins are dissolved in water, alcohol, or a solvent such as liquefied petroleum gas (LPG) mainly composed of propane, butane and isobutane, or further, this hair cosmetic base is used as another resin (anion). Resin, cationic resin, nonionic resin, amphoteric resin, etc.) and other additives to prepare various types of hair cosmetics such as hair spray, hair mousse, hair set lotion, hair gel, etc. Is done.
　しかし、ポリビニルピロリドン以外のノニオン性樹脂は特定の溶媒に対する溶解性を示すのみであり、水溶性、アルコール溶解性、液化石油ガス（ＬＰＧ）溶解性の全てを兼ね備えるものではない。このため、毛髪化粧料の溶媒及び添加剤を変更するごとに、ノニオン性樹脂も変更しなければならず、毛髪化粧料の配合成分を変更することが困難になるという問題がある。 However, nonionic resins other than polyvinylpyrrolidone only exhibit solubility in a specific solvent, and do not have all of water solubility, alcohol solubility, and liquefied petroleum gas (LPG) solubility. For this reason, whenever it changes the solvent and additive of hair cosmetics, a nonionic resin must also be changed and there exists a problem that it becomes difficult to change the compounding component of hair cosmetics.
　また、ポリビニルピロリドンは上記の通り各種溶媒に対する溶解性を示すが、Ｎ－ビニル－２－ピロリドン単独の重合体であるため、その特性を調整するための手段は分子量の変更だけであり、各種溶剤に対する溶解性や、ガラス転移点、粘着性等の特性を調整することは困難であった。 Polyvinylpyrrolidone shows solubility in various solvents as described above, but since it is a polymer of N-vinyl-2-pyrrolidone alone, the only means for adjusting its properties is to change the molecular weight. It was difficult to adjust properties such as solubility in glass, glass transition point, and tackiness.
　本発明は上記問題を解決するためになされたものであり、水溶性、アルコール溶解性及び液化石油ガス（ＬＰＧ）溶解性を兼ね備え、且つ化粧料用基剤としての特性の調整も容易であり、特に毛髪化粧料用基剤として有用なノニオン性樹脂からなる化粧料用基剤、並びにこの化粧料用基剤を含有する化粧料を提供することを目的とする。 The present invention has been made in order to solve the above-mentioned problems, has water solubility, alcohol solubility and liquefied petroleum gas (LPG) solubility, and can easily adjust the properties as a cosmetic base, It aims at providing the cosmetic base which consists of nonionic resin especially useful as a base for hair cosmetics especially, and the cosmetics containing this cosmetic base.

The nonionic unsaturated monomer (a) contains N, N-dimethylacrylamide (a1) represented by the following chemical formula (1) as an essential component.
　本発明に係る化粧料用基剤はノニオン性樹脂であるため、アニオン性樹脂、カチオン性樹脂、両性樹脂等の他の樹脂と併用しても相溶性不足の問題が生じにくい。またこの化粧料用基剤は水、アルコール、液化石油ガス（ＬＰＧ）のうちいずれの溶媒に対しても良好な溶解性を示す。更に、エチレン性不飽和単量体成分（Ａ）の組成が調整されることで、化粧料用基剤の各種溶媒への溶解性や、ガラス転移点、粘着性等の化粧料用基剤としての特性が容易に調整される。従って、この化粧料用基剤から毛髪化粧料等の化粧料を調製する際、化粧料用基剤の特性を適宜調整したり、化粧料に種々の樹脂や溶媒を配合することが容易となり、化粧料の組成設計の自由度が向上する。 Since the cosmetic base according to the present invention is a nonionic resin, the problem of insufficient compatibility hardly occurs even when used in combination with other resins such as an anionic resin, a cationic resin, and an amphoteric resin. This cosmetic base exhibits good solubility in any solvent of water, alcohol, and liquefied petroleum gas (LPG). Furthermore, by adjusting the composition of the ethylenically unsaturated monomer component (A), the cosmetic base such as the solubility of the cosmetic base in various solvents, the glass transition point, and the adhesiveness can be used. The characteristics are easily adjusted. Therefore, when preparing cosmetics such as hair cosmetics from this cosmetic base, it becomes easy to appropriately adjust the properties of the cosmetic base, or to blend various resins and solvents into the cosmetic, The degree of freedom of cosmetic composition design is improved.

Note that “(meth) acryl-” in the notation of the following compound names means “acryl-” and / or “methacryl-”.
　本発明に係る化粧料用基剤は、ノニオン性不飽和単量体（ａ）を含むエチレン性不飽和単量体成分（Ａ）を重合させた重合体である。前記ノニオン性不飽和単量体（ａ）には、化学式（１）に示されるＮ，Ｎ－ジメチルアクリルアミド（ａ１）が必須成分として含まれる。 The cosmetic base according to the present invention is a polymer obtained by polymerizing an ethylenically unsaturated monomer component (A) containing a nonionic unsaturated monomer (a).

In order to exhibit particularly excellent solubility, the content of N, N-dimethylacrylamide (a1) is preferably in the range of 10 to 100% by weight based on the total amount of the ethylenically unsaturated monomer component (A). . When the content is in the range of 20 to 100% by weight, or further in the range of 30 to 100% by weight, the cosmetic base exhibits further excellent solubility.

And quaternized with -12 alkyl chloride, dialkyl sulfuric acid, dialkyl carbonate, benzyl chloride, etc.).

　両性不飽和単量体が使用される場合、エチレン性不飽和単量体成分（Ａ）中には両性不飽和単量体そのものが含有されていても良いが、両性不飽和単量体の前駆体が含有されていても良い。両性不飽和単量体の前駆体としては、ジメチルアミノエチル（メタ）アクリレート、ジメチルアミノプロピル（メタ）アクリレート、ジエチルアミノエチル（メタ）アクリレート等の（メタ）アクリル酸のアミン誘導体；ジメチルアミノエチル（メタ）アクリルアミド、ジメチルアミノプロピル（メタ）アクリルアミド等の（メタ）アクリルアミド誘導体等が挙げられる。この場合、両性不飽和単量体の前駆体を含むエチレン性不飽和単量体成分（Ａ）が重合された後、得られる重合体中の、両性不飽和単量体の前駆体に由来する構造単位が、両性化剤（モノクロロ酢酸、モノブロモプロピオン酸、プロピオラクトン等のラクトン類；プロパンサルトン等のサルトン類等）で両性化される。両性化により副次的に生成する塩は、必要に応じて濾過、イオン交換等の適宜の手法で除去される。このように両性不飽和単量体の前駆体が使用されると、予め両性化された単量体が使用される場合よりも重合反応が安定化する。 When the amphoteric unsaturated monomer is used, the ethylenically unsaturated monomer component (A) may contain the amphoteric unsaturated monomer itself. The body may be contained. Examples of the amphoteric unsaturated monomer precursor include amine derivatives of (meth) acrylic acid such as dimethylaminoethyl (meth) acrylate, dimethylaminopropyl (meth) acrylate, and diethylaminoethyl (meth) acrylate; dimethylaminoethyl (meth) And (meth) acrylamide derivatives such as acrylamide and dimethylaminopropyl (meth) acrylamide. In this case, after the ethylenically unsaturated monomer component (A) containing the amphoteric unsaturated monomer precursor is polymerized, it is derived from the amphoteric unsaturated monomer precursor in the obtained polymer. The structural unit is amphotericized with an amphoteric agent (monochloroacetic acid, monobromopropionic acid, lactones such as propiolactone; sultones such as propane sultone). The salt generated as a result of amphotericization is removed by an appropriate method such as filtration or ion exchange as necessary. Thus, when the precursor of an amphoteric unsaturated monomer is used, the polymerization reaction is more stable than when a previously amphoteric monomer is used.
　エチレン性不飽和単量体成分（Ａ）は、適宜の重合方法で重合される。前記重合方法として、例えば親水性溶媒を用いた通常の溶液重合法等の公知の重合方法が採用され得る。溶液重合法が採用される場合、例えば親水性溶媒中にエチレン性不飽和単量体成分（Ａ）を溶解すると共に重合開始剤を添加して反応溶液を調製し、この反応溶液を窒素気流下、溶媒の沸点又はそれに近い温度で攪拌することによってエチレン性不飽和単量体成分（Ａ）を重合させることができる。この反応溶液中には重合反応の開始当初からエチレン性不飽和単量体成分（Ａ）の全種及び全量が溶解していても良いが、エチレン性不飽和単量体成分（Ａ）の種類、量等に応じて、重合反応を進行させながら反応溶液中にエチレン性不飽和単量体成分（Ａ）を分割して添加し、或いは重合反応を進行させながら反応溶液中にエチレン性不飽和単量体成分（Ａ）を連続滴下しても良い。前記親水性溶媒の使用量は、重合反応終了時の溶液中の樹脂固形分濃度が３０～８０重量％の範囲となるように調整されることが好ましい。 The ethylenically unsaturated monomer component (A) is polymerized by an appropriate polymerization method. As the polymerization method, for example, a known polymerization method such as a normal solution polymerization method using a hydrophilic solvent may be employed. When the solution polymerization method is employed, for example, a reaction solution is prepared by dissolving the ethylenically unsaturated monomer component (A) in a hydrophilic solvent and adding a polymerization initiator. The ethylenically unsaturated monomer component (A) can be polymerized by stirring at or near the boiling point of the solvent. In this reaction solution, all kinds and all amounts of the ethylenically unsaturated monomer component (A) may be dissolved from the beginning of the polymerization reaction. Depending on the amount, etc., the ethylenically unsaturated monomer component (A) is dividedly added to the reaction solution while the polymerization reaction proceeds, or the ethylenically unsaturated component is added to the reaction solution while the polymerization reaction proceeds. The monomer component (A) may be continuously dropped. The amount of the hydrophilic solvent used is preferably adjusted so that the resin solids concentration in the solution at the end of the polymerization reaction is in the range of 30 to 80% by weight.
　溶液重合に使用される親水性溶媒としては、例えばメタノール、エタノール、２－プロパノール、ブタノール等の水に可溶な脂肪族アルコール；アセトン；メチルセロソルブ；エチルセロソルブ；ジオキサン；酢酸メチル；酢酸エチル；ジメチルホルムアミド等が挙げられる。親水性溶媒は一種単独で使用され、或いは二種以上が併用される。 Examples of the hydrophilic solvent used in the solution polymerization include aliphatic alcohols soluble in water such as methanol, ethanol, 2-propanol, and butanol; acetone; methyl cellosolve; ethyl cellosolve; dioxane; methyl acetate; ethyl acetate; And formamide. A hydrophilic solvent is used individually by 1 type, or 2 or more types is used together.
　重合開始剤としては適宜のものが使用されるが、例えば過酸化ベンゾイル、過酸化ラウロイル等の過酸化物；２，２’－アゾビスイソブチロニトリル、２，２’－アゾビス－２－メチルブチロニトリル、２，２’－アゾビス－２，４－ジメチルバレロニトリル、１，１’－アゾビス－１－シクロヘキサンカルボニトリル、４，４’－アゾビスー４－シアノ吉草酸、２，２’－アゾビス－（２－アミジノプロパン）－ジヒドロクロリド等のアゾ系化合物等を使用することが好ましい。 Any suitable polymerization initiator may be used. For example, peroxides such as benzoyl peroxide and lauroyl peroxide; 2,2′-azobisisobutyronitrile, 2,2′-azobis-2-methyl Butyronitrile, 2,2'-azobis-2,4-dimethylvaleronitrile, 1,1'-azobis-1-cyclohexanecarbonitrile, 4,4'-azobis-4-cyanovaleric acid, 2,2'-azobis It is preferable to use an azo compound such as-(2-amidinopropane) -dihydrochloride.
　また、反応溶液中には、分子量調節等のため、必要に応じて連鎖移動剤が添加されても良い。連鎖移動剤としては、特に限定されないが、例えばラウリルメルカプタン、ドデシルメルカプタン、チオグリセロール等のメルカプタン基を有する化合物；次亜リン酸ナトリウム、亜硫酸水素ナトリウム等の無機塩等が挙げられる。連鎖移動剤の使用量は、通常、エチレン性不飽和単量体成分（Ａ）の総量１００重量部に対して０．０１～１０重量部の範囲が好ましい。 In addition, a chain transfer agent may be added to the reaction solution as necessary for molecular weight adjustment or the like. The chain transfer agent is not particularly limited, and examples thereof include compounds having a mercaptan group such as lauryl mercaptan, dodecyl mercaptan, and thioglycerol; inorganic salts such as sodium hypophosphite and sodium bisulfite. The amount of chain transfer agent used is usually preferably in the range of 0.01 to 10 parts by weight with respect to 100 parts by weight of the total amount of the ethylenically unsaturated monomer component (A).
　また、リビングラジカル重合法によりエチレン性不飽和単量体成分（Ａ）を重合させても良い。この場合、連鎖移動剤を使用する場合よりも分子量分布の狭い重合体が生成する。 Further, the ethylenically unsaturated monomer component (A) may be polymerized by a living radical polymerization method. In this case, a polymer having a narrower molecular weight distribution is formed than when a chain transfer agent is used.
　エチレン性不飽和単量体成分（Ａ）の重合時の温度、時間等の重合条件は、エチレン性不飽和単量体成分（Ａ）や重合開始剤の種類等に応じ、高い反応率で重合反応が進行するように適宜設定される。重合反応は、窒素ガス、アルゴンガス等の不活性ガスの雰囲気下で行っても良い。重合反応終了時の未反応モノマーの残存量は少量であるほど好ましい。 Polymerization conditions such as temperature and time during the polymerization of the ethylenically unsaturated monomer component (A) are polymerized at a high reaction rate according to the type of the ethylenically unsaturated monomer component (A) and the polymerization initiator. It sets suitably so that reaction may advance. The polymerization reaction may be performed in an atmosphere of an inert gas such as nitrogen gas or argon gas. The smaller the amount of unreacted monomer remaining at the end of the polymerization reaction, the better.
　このようなエチレン性不飽和単量体成分（Ａ）の重合反応により、ノニオン性樹脂からなる化粧料用基剤が生成する。溶液重合法の場合は、化粧料用基剤の親水性溶媒溶液が生成する。この化粧料用基剤が毛髪化粧料用基剤としてバランスの優れた特性、すなわち例えば毛髪に付着した場合に洗髪による容易に除去可能であり、粘度が毛髪化粧料中に配合可能な程度であると共に製法上製造可能な程度であり、更に経皮吸収が起こりにくい等の特性を備えるためには、この化粧料用基剤の重量平均分子量が好ましくは１０００～１００００００の範囲、更に好ましくは１０００～５０００００の範囲、更に好ましくは１０００～２０００００の範囲となるようにする。 A cosmetic base composed of a nonionic resin is produced by such a polymerization reaction of the ethylenically unsaturated monomer component (A). In the case of the solution polymerization method, a hydrophilic solvent solution of a cosmetic base is produced. This cosmetic base has an excellent balance as a hair cosmetic base, that is, for example, it can be easily removed by shampooing when attached to the hair, and the viscosity can be incorporated into the hair cosmetic. In addition, in order to have properties such that it can be produced by a manufacturing method and is less likely to cause percutaneous absorption, the weight average molecular weight of the cosmetic base is preferably in the range of 1,000 to 1,000,000, more preferably 1,000 to 1,000. The range is 500,000, more preferably in the range of 1,000 to 200,000.
　この化粧料用基剤に必要に応じて種々の成分が配合されることで、適宜の化粧料が調製される。溶液重合法によって化粧料用基剤の親水性溶媒溶液が生成する場合には、この親水性溶媒溶液に必要に応じて種々の成分が配合されることで、化粧料が調製される。また、この親水性溶媒溶液から親水性溶媒を留去して得られる固形状の化粧料用基剤に必要に応じて種々の成分が配合されることで、化粧料が調製されても良い。 An appropriate cosmetic is prepared by blending various ingredients as necessary in this cosmetic base. When a hydrophilic solvent solution of a cosmetic base is produced by the solution polymerization method, cosmetics are prepared by blending various components in the hydrophilic solvent solution as necessary. Moreover, cosmetics may be prepared by blending various components as required in a solid cosmetic base obtained by distilling off the hydrophilic solvent from the hydrophilic solvent solution.
　この化粧料用基剤は、特に毛髪化粧料の調製のために好適に使用される。 This cosmetic base is suitably used especially for the preparation of hair cosmetics.

By doing so, a hair spray is prepared. The solid content concentration of the cosmetic base in the hair spray is preferably in the range of 0.5 to 15% by weight.

Examples thereof include halogenated hydrocarbons containing chloride, hydrofluorocarbon (HFC152a and the like) as components, dimethyl ether, carbon dioxide gas and the like. These propellants are used alone or in combination of two or more. In particular, since the cosmetic base according to the present invention has high LPG solubility, LPG is preferably used. It is preferable that the hair spray agent and the propellant are enclosed in a pressure vessel in a weight ratio of 2: 8 to 8: 2.
　また、この化粧料用基剤は水溶性及びアルコール溶解性が高いため、この化粧料用基剤が親水性溶媒又は水と親水性溶媒との混合溶媒に溶解され、更に各種添加剤が加えられることで、ヘアクリーム、ヘアワックス、ヘアローション、ノンガスエアゾール剤（ヘアミスト剤）、ヘアゲル、ヘアスタイリングフォーム（ヘアムース）、カーラーウォーター等の毛髪化粧料が調製される。 Further, since this cosmetic base is highly water-soluble and alcohol-soluble, this cosmetic base is dissolved in a hydrophilic solvent or a mixed solvent of water and a hydrophilic solvent, and various additives are further added. Thus, hair cosmetics such as hair cream, hair wax, hair lotion, non-gas aerosol agent (hair mist agent), hair gel, hair styling foam (hair mousse), curler water and the like are prepared.

The In addition, a base for cosmetics is used for preparing appropriate hair cosmetics such as hair treatment agents, hair conditioners, hair shampoos, hair rinses and the like.
　また、この化粧料用基剤は、毛髪化粧料以外の化粧料の調製のためにも使用される。例えばこの化粧料用基剤が、スキンクリーム、スキンクリーム、シェービングフォーム、その他メイクアップ製品等に配合される皮膜形成剤として使用される。 This cosmetic base is also used for the preparation of cosmetics other than hair cosmetics. For example, this cosmetic base is used as a film forming agent to be blended in skin creams, skin creams, shaving foams, and other makeup products.
　この化粧料用基剤はノニオン性樹脂であるため、化粧料の調製時には、この化粧料用基剤と、アニオン性樹脂、カチオン性樹脂、両性樹脂及び前記化粧料用基剤以外のノニオン性樹脂から選ばれる少なくとも一種の樹脂とが併用されても良い。 Since this cosmetic base is a nonionic resin, at the time of preparation of the cosmetic, this cosmetic base, and an anionic resin, a cationic resin, an amphoteric resin, and a nonionic resin other than the cosmetic base are used.
