Description

【0001】
【発明の属する技術分野】
本発明は、毛髪に好ましいコンディショニング効果を賦与し、更にその効果の持続性に優れた毛髪化粧料に関する。
【0002】
【従来の技術及び発明が解決しようとする課題】
毛髪に好ましいコンディショニング効果を賦与する目的で種々の油剤や高分子化合物(以下、基剤と言う)が用いられている。例えば、高重合ポリシロキサン等のシリコーン化合物や特開平10−45545号に記載の樹枝状高分子(Dendrimer)等である。
【0003】
しかし、これらは、コンディショニング効果が不十分であるだけでなくシャンプー処理により容易に洗い落とされ、効果の持続性に劣るという問題があった。本発明の課題は十分な毛髪のしっとり感、なめらかさなどのコンディショニング効果とその効果の持続性を飛躍的に改善した毛髪化粧料を提供することである。
【0004】
【課題を解決するための手段】
本発明者は、星状の結合形式を有する重合体を配合するとコンディショニング効果に優れ、かつその効果が飛躍的に向上した毛髪化粧料が得られることを見出した。
【0005】
すなわち、本発明は一つの分岐点(以下、コア部という)を有し、そのコア部より3本以上のポリマー鎖(以下、アーム部という。ポリマー鎖は直鎖状であるか又は規則的に多分岐したものではない分岐鎖状である。)を有する重合体(以下、星状重合体という)を含有する毛髪化粧料を提供するものである。
【0006】
この場合において「規則的に多分岐した」とは、次のことを意味する。すなわち、第1世代の重合単位、第2世代の重合単位、・・・、第n世代の重合単位、第(n+1)世代の重合単位(nは4以上の整数)が認識できる様式の分岐であって第1世代の重合単位は末端位において2つ以上の枝分かれを有し、その枝分かれは第2世代の重合単位の重合単位を構成し、第2世代の重合単位の末端位は2つ以上の枝分かれを有し、その枝分かれは第3世代の重合単位を構成する。以下、この繰り返しであって、第n世代の重合単位の末端位は2つ以上の枝分かれを有し、第(n+1)世代の重合単位を構成し、かつ第1世代同士、第2世代同士、第3世代同士、・・・、第n世代同士は同じ構造を有することを意味する。このように規則的に多分岐した分岐鎖をもつ重合体としてDendrimerがあり、例えば特開平10−45545号に開示されるものである。
【0007】
【発明の実施の形態】
星状重合体のコア部としては低分子量の原子団(例えば炭素原子、窒素原子、ケイ素原子、ベンゼン環等)、多官能単量体の架橋体、又は無機微粒子(例えばシリカ)等が挙げられる。多官能単量体の架橋体の場合、ジビニルベンゼン、(ポリ)アルキレングリコールジ(メタ)アクリレート、トリメチロールプロパントリアクリレート、ペンタエリスリトールテトラアクリレート等の重合物が好適に用いられる。通常、反応性等の都合からジビニルベンゼンを用いることが好ましい。
【0008】
1分子中に占めるコア部の割合に特に制限はないが、好ましくは1〜50重量%である。
【0009】
本発明の星状重合体のアーム部は、直鎖状のポリマー鎖であることが好ましいが、分岐鎖を有していてもよい。しかしその場合であってもアーム部は前述のような「規則的に多分岐した」分岐鎖を有さない。
【0010】
星状重合体のアーム部を構成するポリマー鎖の種類に特に制約はないが、例えば、ポリスチレン、(水添)ポリイソプレン、(水添)ポリブタジエン、ポリエチレン、ポリプロピレン、ポリイソブチレン等の炭化水素系ポリマー類;メタクリル酸メチル、アクリル酸ブチル等のポリ(メタ)アクリル酸アルキルエステル類;ポリオキシエチレン、ポリオキシプロピレン等のポリアルキレンオキシド類;ポリラクチド、ポリカプロラクタム等のポリエステル類;ポリジメチルシロキサン等のシリコーン類等が例示される。これらがブロック状あるいはランダム状に共重合していてもよいし、異なるポリマー鎖からなるアームがひとつのコアに連結したいわゆるヘテロアーム重合体でも良い。
【0011】
アーム部を構成するポリマー鎖のガラス転移点(Tg)に特に制限はないが、通常−120℃〜250℃、好ましくは−120℃〜0℃である。Tgが低く、20〜25℃で液体を呈する星状重合体は特に優れたコンディショニング効果を示す。アーム部のポリマー鎖の数平均分子量はコンディショニング効果とその持続性の両立の点から、1000から10万、好ましくは2000〜5万、更に好ましくは3000〜2万である。
【0012】
更に、コア部から放射状にのびるアーム部の数は、コンディショニング効果の持続性の点から、コア部1分子当たり3本以上、より好ましくは5本以上、更には7本以上が最も好ましい。
【0013】
星状重合体の重量平均分子量は、コンディショニング効果及びその持続性の点から、好ましくは3000以上、より好ましくは5000以上、特に好ましくは7000以上である。
【0014】
星状重合体の合成法としては、例えばアーム部分を先に合成した後に多官能のコア部と連結する方法(アームファースト法)、及びコアとなる多官能の開始点からアーム部を重合する方法(コアファースト法)がある。アームファースト法の特別な場合としては、一官能性モノマーのアームを合成した後に多官能モノマーを重合させてコアを形成させる方法もある(逐次重合法)。この逐次重合法の後更に別のモノマーを加えてヘテロアームスターポリマーとしたり、活性末端を適当な試薬と反応させて官能基を導入することもできる。これらの合成法の具体例としてはPaul Rempp et al.,Makromol.Chem.第189巻,2,第1051頁,1988年及びその引用文献を例示することができる。
【0015】
星状重合体の毛髪化粧料への配合量はコンディショニング効果及びその持続性の点から、0.01〜50重量%(以下単に%で示す)、特に0.05〜30%が好ましい。
【0016】
本発明毛髪化粧料には、更に油剤、特に毛髪に対してコンディショニング作用を有する油剤を配合するのが好ましい。この油剤としては、特開平8−198732号、第7頁第12欄35行〜第8頁第13欄44行に記載のもの、例えば炭素数12〜30の飽和又は不飽和アルコール類;当該アルコール類と多価アルコールとのエーテル類;当該アルコール類と炭素数1〜11の脂肪酸とのエステル類;炭素数12〜30の飽和又は不飽和脂肪酸;当該脂肪酸と一価又は多価アルコールとのエステル類;当該脂肪酸とアミン類とのアミド類;ステロール類;スクアレン;リン脂質;糖脂質;動物性油脂;植物性油脂が挙げられる。油剤としては更に、ジメチルポリシロキサン、メチルポリシロキサン、ポリシロキサン、アミノ変性シリコーン、アルキル変性シリコーン、メチルフェニルポリシロキサン、ポリエーテル変性シリコーン等のシリコーン誘導体が挙げられる。
【0017】
これら油剤の毛髪化粧料への配合量は、通常0.01〜30%、好ましくは1〜25%、更に好ましくは3〜20%である。
【0018】
更に、本発明の毛髪化粧料には本発明の効果を損なわない範囲で、必要に応じてヒドロキシエチルセルロース等の増粘剤、アニオン性・両性・カチオン性・非イオン性界面活性剤、アニオン性・両性・カチオン性・非イオン性重合物、香料、パール化剤、色素、紫外線吸収剤、酸化防止剤、防腐剤等を配合しても良い。
【0019】
本発明の毛髪化粧料は、例えば浴室内で用いるようなヘアシャンプー、ヘアトリートメント、ヘアコンディショナーや浴室外で用いるヘアフォーム、ヘアスプレー、ヘアクリーム、ヘアワックス、ヘアジェル、更には、ヘアダイ、パーマ、ヘアマニキュア、ヘアブリーチ等家庭や美容室での施術に用いられる剤にも配合できる。

合成例
乾燥アルゴン置換したフラスコにシクロヘキサン、イソプレン、n−ブチルリチウム、トリエチルアミンを仕込み、室温で24時間重合させてアーム部を合成した。反応液は僅かに黄色を呈し、微弱な発熱と粘度の増大が認められた。この時点でサンプリングしGPCによりアーム部の数平均分子量を求めた。
次にジビニルベンゼンのシクロヘキサン溶液を添加し、30℃で24時間反応させることにより連結反応を行った。ジビニルベンゼン添加により反応液は僅かに濁り、橙色から濃赤色へと変化した。
反応後、脱気したエタノールを加えて反応を停止し、希塩酸洗浄、水洗した。更に溶液にシクロヘキサン/エタノール混合溶媒(2/1)で洗浄して未反応アーム部を除去した後、メンブラン濾過(PTFE,0.2μm)により微量のゲル化物を除去した。濾液にBHTを加えた後、減圧乾燥により溶媒を除去し目的の粘稠オイルを得た。

本発明の毛髪化粧料によれば、毛髪にしっとり感や、なめらかさを与えることができその効果の持続が極めて優れている。[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a hair cosmetic composition that imparts a favorable conditioning effect to hair and is excellent in the sustainability of the effect.
[0002]
[Prior art and problems to be solved by the invention]
Various oils and polymer compounds (hereinafter referred to as bases) are used for the purpose of imparting a favorable conditioning effect to the hair. Examples thereof include silicone compounds such as highly polymerized polysiloxane, dendritic polymers described in JP-A-10-45545, and the like.
[0003]
However, these have a problem that not only the conditioning effect is insufficient, but they are easily washed out by shampoo treatment and the durability of the effect is inferior. An object of the present invention is to provide a hair cosmetic material that has drastically improved conditioning effects such as sufficient moist feeling and smoothness of hair and the sustainability of the effects.
[0004]
[Means for Solving the Problems]
The present inventor has found that when a polymer having a star-like bond form is blended, a hair cosmetic that is excellent in the conditioning effect and whose effect is greatly improved can be obtained.
[0005]
That is, the present invention has one branch point (hereinafter referred to as a core portion), and three or more polymer chains (hereinafter referred to as arm portions) from the core portion. The polymer chain is linear or regularly. The present invention provides a hair cosmetic containing a polymer having a branched chain that is not multi-branched) (hereinafter referred to as a star polymer).
[0006]
In this case, “regularly multi-branched” means the following. That is, the first generation polymerization unit, the second generation polymerization unit,..., The nth generation polymerization unit, the (n + 1) th generation polymerization unit (n is an integer of 4 or more) can be recognized. The first generation polymer unit has two or more branches at the terminal position, and the branch constitutes a polymer unit of the second generation polymer unit, and the terminal position of the second generation polymer unit is two or more. The branch constitutes a third generation polymer unit. Hereinafter, this is repeated, the terminal position of the nth generation polymer unit has two or more branches, constitutes the (n + 1) th generation polymer unit, and the first generation, the second generation, It means that the third generations,..., The nth generation have the same structure. A dendrimer is a polymer having a branched chain that is regularly multi-branched as described above, and is disclosed in, for example, Japanese Patent Application Laid-Open No. 10-45545.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Examples of the core of the star-shaped polymer include low molecular weight atomic groups (for example, carbon atoms, nitrogen atoms, silicon atoms, benzene rings), crosslinked polyfunctional monomers, and inorganic fine particles (for example, silica). . In the case of a cross-linked product of a polyfunctional monomer, a polymer such as divinylbenzene, (poly) alkylene glycol di (meth) acrylate, trimethylolpropane triacrylate, pentaerythritol tetraacrylate is preferably used. Usually, it is preferable to use divinylbenzene for convenience of reactivity.
[0008]
The ratio of the core part in one molecule is not particularly limited, but is preferably 1 to 50% by weight.
[0009]
The arm portion of the star polymer of the present invention is preferably a linear polymer chain, but may have a branched chain. However, even in that case, the arm portion does not have the “regularly multi-branched” branched chain as described above.
[0010]
There are no particular restrictions on the type of polymer chain constituting the arm portion of the star polymer, but for example, hydrocarbon polymers such as polystyrene, (hydrogenated) polyisoprene, (hydrogenated) polybutadiene, polyethylene, polypropylene, polyisobutylene, etc. Polyalkyl (meth) acrylates such as methyl methacrylate and butyl acrylate; polyalkylene oxides such as polyoxyethylene and polyoxypropylene; polyesters such as polylactide and polycaprolactam; silicones such as polydimethylsiloxane Examples are shown. These may be copolymerized in a block form or a random form, or may be a so-called heteroarm polymer in which arms composed of different polymer chains are linked to one core.
[0011]
Although there is no restriction | limiting in particular in the glass transition point (Tg) of the polymer chain which comprises an arm part, Usually, -120 to 250 degreeC, Preferably it is -120 to 0 degreeC. A star polymer having a low Tg and exhibiting a liquid at 20 to 25 ° C. exhibits a particularly excellent conditioning effect. The number average molecular weight of the polymer chain in the arm portion is 1000 to 100,000, preferably 2000 to 50,000, and more preferably 3000 to 20,000, from the viewpoint of compatibility between the conditioning effect and its sustainability.
[0012]
Furthermore, the number of arm portions extending radially from the core portion is most preferably 3 or more, more preferably 5 or more, and even more preferably 7 or more, per molecule of the core portion from the viewpoint of sustaining the conditioning effect.
[0013]
The weight average molecular weight of the star polymer is preferably 3000 or more, more preferably 5000 or more, particularly preferably 7000 or more, from the viewpoint of the conditioning effect and its sustainability.
[0014]
As a method for synthesizing a star-shaped polymer, for example, a method in which an arm portion is first synthesized and then linked to a polyfunctional core portion (arm first method), and a method in which the arm portion is polymerized from a polyfunctional starting point serving as a core (Core first method). As a special case of the arm first method, there is a method in which a core is formed by polymerizing a polyfunctional monomer after synthesizing an arm of a monofunctional monomer (sequential polymerization method). After this sequential polymerization method, another monomer can be added to form a heteroarm star polymer, or a functional group can be introduced by reacting the active terminal with an appropriate reagent. Specific examples of these synthesis methods include those described in Paul Rempp et al. , Makromol. Chem. 189, 2, page 1051, 1988, and cited references.
[0015]
The blending amount of the star polymer in the hair cosmetic is preferably 0.01 to 50% by weight (hereinafter simply referred to as “%”), particularly 0.05 to 30% from the viewpoint of the conditioning effect and its sustainability.
[0016]
The hair cosmetic composition of the present invention preferably further contains an oil agent, particularly an oil agent having a conditioning action on the hair. Examples of the oil include those described in JP-A-8-198732, page 7, column 12, line 35 to page 8, column 13, line 44, for example, saturated or unsaturated alcohols having 12 to 30 carbon atoms; Ethers of alcohols and polyhydric alcohols; esters of the alcohols and fatty acids having 1 to 11 carbon atoms; saturated or unsaturated fatty acids having 12 to 30 carbon atoms; esters of the fatty acids and monohydric or polyhydric alcohols Amides of the fatty acid and amines; sterols; squalene; phospholipids; glycolipids; animal fats and oils; Examples of the oil agent further include silicone derivatives such as dimethylpolysiloxane, methylpolysiloxane, polysiloxane, amino-modified silicone, alkyl-modified silicone, methylphenylpolysiloxane, and polyether-modified silicone.
[0017]
The blending amount of these oils into the hair cosmetic is usually 0.01 to 30%, preferably 1 to 25%, more preferably 3 to 20%.
[0018]
Furthermore, in the hair cosmetic composition of the present invention, a thickener such as hydroxyethyl cellulose, anionic / amphoteric / cationic / nonionic surfactant, anionic / Amphoteric / cationic / nonionic polymers, fragrances, pearling agents, dyes, UV absorbers, antioxidants, preservatives, and the like may be blended.
[0019]
The hair cosmetic composition of the present invention includes, for example, hair shampoos, hair treatments, hair conditioners and hair foams used outside the bathroom, hair sprays, hair creams, hair waxes, hair gels, and hair dyes, perms, hairs. It can also be added to agents used in home and beauty salon treatments such as manicure and hair bleach.
[0020]
【Example】
Synthesis Example Cyclohexane, isoprene, n-butyllithium, and triethylamine were charged into a dry argon-substituted flask and polymerized at room temperature for 24 hours to synthesize an arm part. The reaction solution was slightly yellow, and a slight exotherm and an increase in viscosity were observed. Sampling was performed at this time, and the number average molecular weight of the arm portion was determined by GPC.
Next, a cyclohexane solution of divinylbenzene was added and a ligation reaction was performed by reacting at 30 ° C. for 24 hours. By adding divinylbenzene, the reaction solution became slightly turbid and changed from orange to dark red.
After the reaction, degassed ethanol was added to stop the reaction, followed by dilute hydrochloric acid washing and water washing. Further, the solution was washed with a cyclohexane / ethanol mixed solvent (2/1) to remove the unreacted arm, and then a small amount of gelled product was removed by membrane filtration (PTFE, 0.2 μm). After adding BHT to the filtrate, the solvent was removed by drying under reduced pressure to obtain the desired viscous oil.
The arm polymer Tg of the star polymer was measured by the method described in footnote 2 of Table 1. The absolute molecular weight of the star polymer was determined by a light scattering method (Otsuka Electronics, DSL-7000DH, solvent cyclohexane, 25 ° C., Zimm plot, 2θ = 30 to 150 °, concentration 0.1 to 1.0%). The synthesis conditions and results are shown in Table 1.

The moist feeling of the hair was judged by touching the hair with a finger, and the smoothness was judged by the fingering property and the combing property. In each example, the nonvolatile content was 2% by weight. The evaluation criteria are as follows.
[0023]
〔Evaluation criteria〕
5: The hair is moist and smooth 4: The hair is moist and smooth 3: The hair is moist and smooth 2: The hair is moist and smooth Slightly low 1: Low moistness and smoothness of hair [0024]
