Description

本発明は、二剤同時吐出型染毛剤に関するものである。 The present invention relates to a two-agent simultaneous ejection type hair dye.

従来のクリームタイプの染毛剤は、アルカリ剤を含む第一剤と酸化剤を含む第二剤とを別々に使用する際には特に問題は生じないが、第一剤と第二剤とを所定の吐出量の比率にて同時に吐出させて使用する場合、第一剤と第二剤との吐出量を調整する必要があり、消費者が使用することを考えると、第一剤と第二剤との吐出量は使い始めから使い終わるまで安定である必要があった。 The conventional cream-type hair dye does not cause any problem when the first agent containing an alkaline agent and the second agent containing an oxidizing agent are used separately, but the first agent and the second agent are used. When using by simultaneously discharging at a predetermined discharge amount ratio, it is necessary to adjust the discharge amount of the first agent and the second agent, and considering that the consumer uses it, the first agent and the second agent are used. The discharge rate with the agent had to be stable from the beginning to the end of use.

しかしながら、単純にクリーム状の染毛剤を、内袋を有する耐圧容器の内袋中に充填し、更に、内袋と耐圧容器間に圧縮ガスを充填したエアゾール容器において、使い始めから使い終わるまでの吐出量を評価したとき、充填する染毛剤によって吐出量が変化するため、第一剤と第二剤とを所定の吐出量の比率にて同時に吐出させて使用する場合、使い始めから使い終わるまで第一剤と第二剤とが所定の吐出量の比率にて同時に吐出出来ないことがあった。 However, in an aerosol container in which a creamy hair dye is simply filled in the inner bag of a pressure-resistant container having an inner bag, and a compressed gas is filled between the inner bag and the pressure-resistant container, from the beginning to the end of use. When the discharge amount of is evaluated, the discharge amount changes depending on the hair dye to be filled. Therefore, when the first agent and the second agent are simultaneously discharged at a predetermined discharge amount ratio, use from the beginning of use. Until the end, the first agent and the second agent could not be discharged at the same time at a predetermined discharge amount ratio.

又、従来のクリームタイプの染毛剤は、第一剤と第二剤とが所定の混合比率になるようトレイ等に出し、コームやブラシできちんと混ぜた後に頭髪に塗布するが、第一剤と第二剤とを所定の吐出量の比率にて同時に吐出させて使用する二剤同時吐出型染毛剤を頭髪に塗布する際、吐出後に直接頭髪に塗布するか、もしくはブラシに出してから頭髪に塗布し、第一剤と第二剤とを頭髪上で混ぜる行為を行うため、第一剤と第二剤とが所定の吐出量の比率にて同時に吐出されていないとムラ染めを引き起こすことがあった。 In the conventional cream-type hair dye, the first agent and the second agent are put out on a tray or the like so as to have a predetermined mixing ratio, mixed properly with a comb or a brush, and then applied to the hair. When applying a two-agent simultaneous discharge type hair dye that is used by simultaneously discharging and the second agent at a predetermined discharge rate ratio, apply it directly to the hair after discharge, or after applying it to a brush. Since it is applied to the hair and the first agent and the second agent are mixed on the hair, uneven dyeing is caused if the first agent and the second agent are not discharged at the same time at a predetermined discharge rate ratio. There was something.

そこで、第一剤及び/又は第二剤にシリコーン類を配合することで、吐出量が変化することなく、経時的吐出量の安定な原液を調製する提案がされている(特許文献1)。 Therefore, it has been proposed to prepare a stock solution having a stable discharge amount over time without changing the discharge amount by blending silicones with the first agent and / or the second agent (Patent Document 1).

特開2004−91356号公報Japanese Unexamined Patent Publication No. 2004-91356

本発明は、第一剤と第二剤とを同時に吐出する機構を有するエアゾール容器に充填した二剤同時吐出型染毛剤において、使い始めから使い終わるまで第一剤と第二剤とを所定の吐出量の比率にて同時に吐出することで、毛髪に対し簡便かつムラなく均一に染め上げることが出来る染毛剤を提供することを目的とする。 According to the present invention, in a two-agent simultaneous discharge type hair dye filled in an aerosol container having a mechanism for simultaneously discharging the first agent and the second agent, the first agent and the second agent are predetermined from the beginning to the end of use. It is an object of the present invention to provide a hair dye capable of easily and evenly dyeing hair by simultaneously discharging at the ratio of the discharge amount of.

本発明者は、上記課題を解決するために鋭意検討した結果、第一剤と第二剤とを同時に吐出する機構を有するエアゾール容器に充填した二剤同時吐出型染毛剤において、第一剤と第二剤との粘度が共に50,000mPa・s以下であり、第一剤と第二剤との粘度の比率を、第一剤/第二剤=0.8〜1.2にすることにより、使い始めから使い終わるまで第一剤と第二剤との吐出量の比率の変化が少なく、安定に所定の吐出量の比率にて同時に吐出することが出来ることを見い出し、本発明を完成させるに至った。 As a result of diligent studies to solve the above problems, the present inventor has found that the first agent is a two-agent simultaneous discharge type hair dye filled in an aerosol container having a mechanism for simultaneously discharging the first agent and the second agent. The viscosities of both the first agent and the second agent are 50,000 mPa · s or less, and the viscosity ratio of the first agent and the second agent is set to 0.8 to 1.2 for the first agent / second agent. As a result, it was found that the ratio of the discharge amount of the first agent and the second agent does not change much from the beginning to the end of use, and stable discharge can be performed at the same time at a predetermined discharge amount ratio, and the present invention is completed. I came to let you.

本発明によれば、第一剤と第二剤とを同時に吐出する機構を有するエアゾール容器に充填した二剤同時吐出型染毛剤において、使い始めから使い終わるまで第一剤と第二剤との吐出量の比率の変化が少なく、安定に所定の吐出量の比率にて同時に吐出することが出来るため、毛髪に対し簡便かつムラなく均一に染め上げることが出来る。 According to the present invention, in a two-agent simultaneous discharge type hair dye filled in an aerosol container having a mechanism for simultaneously discharging the first agent and the second agent, the first agent and the second agent are used from the beginning to the end of use. Since the change in the discharge amount ratio of the hair is small and the hair can be stably discharged at the same time at a predetermined discharge amount ratio, the hair can be dyed easily and evenly.

本発明にある吐出量とは重量であり、比率とは、特に記載がない限り重量比であり、第一剤と第二剤との所定の吐出量の比率は任意に設定可能である。 The discharge amount in the present invention is a weight, and the ratio is a weight ratio unless otherwise specified, and a predetermined discharge amount ratio between the first agent and the second agent can be arbitrarily set.

本発明の二剤同時吐出型染毛剤は、アルカリ剤を含有する第一剤と酸化剤を含有する第二剤とからなり、第一剤と第二剤との粘度が共に50,000mPa・s以下であることを特徴とする。毛髪への塗布後の伸び、タレ落ちを考慮すると、好ましくは5,000〜25,000mPa・sである。50,000mPa・sを超えると圧縮ガス等による容器からの吐出が困難になるため、吐出量にムラが生じ、所定の吐出量の比率にて同時に吐出することが困難になる。 The two-agent simultaneous discharge type hair dye of the present invention comprises a first agent containing an alkaline agent and a second agent containing an oxidizing agent, and the viscosities of both the first agent and the second agent are 50,000 mPa. It is characterized in that it is s or less. Considering the elongation after application to the hair and the sagging drop, it is preferably 5,000 to 25,000 mPa · s. If it exceeds 50,000 mPa · s, it becomes difficult to discharge the compressed gas from the container, so that the discharge amount becomes uneven and it becomes difficult to simultaneously discharge at a predetermined discharge amount ratio.

尚、粘度とは、二剤同時吐出型染毛剤の第一剤と第二剤とを別々の容器に吐出した各剤を20度に調温し、TVB−10型粘度計(東機産業株式会社)でSPINDLE NO.M4(CODE NO.23)を使用し、12rpmで回転させてから1分後に測定したものとする。 In addition, the viscosity is a TVB-10 type viscometer (Toki Sangyo), in which the first agent and the second agent of the two-agent simultaneous discharge type hair dye are discharged to separate containers and the temperature is adjusted to 20 degrees. Co., Ltd.) SPINDLE NO. It is assumed that the measurement was performed 1 minute after the rotation at 12 rpm using M4 (CODE NO.23).

本発明の二剤同時吐出型染毛剤は、アルカリ剤を含有する第一剤と酸化剤を含有する第二剤とからなり、第一剤と第二剤との粘度の比率が、第一剤/第二剤=0.8〜1.2であることを特徴とする。好ましくは0.9〜1.1である。粘度の比率が0.8未満であると、第二剤に比べ第一剤の粘度が低いため、第一剤が吐出し易くなり、第一剤の吐出量が多くなる。粘度の比率が1.2を超えると、第一剤に比べ第二剤の粘度が低いため、第二剤が吐出し易くなり、第二剤の吐出量が多くなる。このように、第一剤と第二剤との粘度に差が生じると第一剤と第二剤との吐出量に差が生じ、第一剤と第二剤とを所定の吐出量の比率にて同時に吐出することが困難になる。 The two-agent simultaneous discharge type hair dye of the present invention comprises a first agent containing an alkaline agent and a second agent containing an oxidizing agent, and the viscosity ratio of the first agent and the second agent is first. The agent / second agent = 0.8 to 1.2. It is preferably 0.9 to 1.1. When the viscosity ratio is less than 0.8, the viscosity of the first agent is lower than that of the second agent, so that the first agent can be easily discharged and the discharge amount of the first agent increases. When the viscosity ratio exceeds 1.2, the viscosity of the second agent is lower than that of the first agent, so that the second agent is easily discharged and the discharge amount of the second agent is increased. In this way, when there is a difference in viscosity between the first agent and the second agent, there is a difference in the discharge amount between the first agent and the second agent, and the ratio of the discharge amount between the first agent and the second agent is predetermined. It becomes difficult to discharge at the same time.

本発明の二剤同時吐出型染毛剤は、第一剤と第二剤とが共に高級アルコールを0.1〜10.0重量%含有することを特徴とする。 The two-agent simultaneous discharge type hair dye of the present invention is characterized in that both the first agent and the second agent contain 0.1 to 10.0% by weight of higher alcohol.

本発明の二剤同時吐出型染毛剤に含有される高級アルコールとしては、例えば、ラウリルアルコール、ミリスチルアルコール、セチルアルコール、ステアリルアルコール、セトステアリルアルコール、アラキルアルコール、ベヘニルアルコール、イソステアリルアルコール、オレイルアルコール、2−ヘキシルデカノール、2−オクチルドデカノール等が挙げられる。これらの中でも特に安定性の点から、直鎖飽和高級アルコールであるラウリルアルコール、ミリスチルアルコール、セチルアルコール、ステアリルアルコール、セトステアリルアルコール、アラキルアルコール、ベヘニルアルコールが好ましい。その含有量は0.1〜10.0重量%、好ましくは0.5〜5.0重量%である。0.1重量%未満であると分離等、剤の経時的安定性に影響があり、10.0重量%を超えると剤の粘度が高くなり、圧縮ガス等による容器からの吐出が困難になるため、吐出量にムラが生じ、第一剤と第二剤とを所定の吐出量の比率にて同時に吐出することが困難になる。 Examples of the higher alcohol contained in the two-agent simultaneous discharge type hair dye of the present invention include lauryl alcohol, myristyl alcohol, cetyl alcohol, stearyl alcohol, cetostearyl alcohol, araquil alcohol, behenyl alcohol, isostearyl alcohol, and oleyl alcohol. , 2-Hexyldecanol, 2-octyldodecanol and the like. Among these, lauryl alcohol, myristyl alcohol, cetyl alcohol, stearyl alcohol, cetostearyl alcohol, araquil alcohol, and behenyl alcohol, which are linear saturated higher alcohols, are particularly preferable from the viewpoint of stability. Its content is 0.1 to 10.0% by weight, preferably 0.5 to 5.0% by weight. If it is less than 0.1% by weight, the stability of the agent over time such as separation will be affected, and if it exceeds 10.0% by weight, the viscosity of the agent will increase and it will be difficult to discharge the agent from the container with compressed gas or the like. Therefore, the discharge amount becomes uneven, and it becomes difficult to simultaneously discharge the first agent and the second agent at a predetermined discharge amount ratio.

本発明の二剤同時吐出型染毛剤には非イオン性界面活性剤を適宜配合することが可能である。非イオン性界面活性剤としては、例えば、ポリオキシエチレン(以下、POEという)アルキルエーテル類、POEアルキルフェニルエーテル類、POE・ポリオキシプロピレン(以下、POPという)アルキルエーテル類、POE脂肪酸類、POEソルビタン脂肪酸エステル類、POEヒマシ油、POE硬化ヒマシ油、POEソルビトールテトラ脂肪酸エステル、グリセリン脂肪酸エステル、ソルビタン脂肪酸エステル、ポリグリセリン脂肪酸エステル、ショ糖脂肪酸エステル、アルキルポリグルコシド、N−アルキルジメチルアミンオキシド、POEプロピレングリコール脂肪酸エステル等が挙げられる。 A nonionic surfactant can be appropriately blended in the two-agent simultaneous ejection type hair dye of the present invention. Examples of the nonionic surfactant include polyoxyethylene (hereinafter referred to as POE) alkyl ethers, POE alkylphenyl ethers, POE / polyoxypropylene (hereinafter referred to as POP) alkyl ethers, POE fatty acids, and POE. Polysorbate fatty acid esters, POE castor oil, POE hardened castor oil, POE sorbitol tetra fatty acid ester, glycerin fatty acid ester, sorbitan fatty acid ester, polyglycerin fatty acid ester, sucrose fatty acid ester, alkyl polyglucoside, N-alkyldimethylamine oxide, POE Examples thereof include propylene glycol fatty acid ester.

これらの中でも酸やアルカリ剤に強いことから、POEアルキルエーテル類、POEアルキルフェニルエーテル類、POE・POPアルキルエーテル類、POEソルビタン脂肪酸エステル類が好ましく、更にこれらの中ではPOEアルキルエーテル類が特に好ましい。POEアルキルエーテル類の具体例としては、POEラウリルエーテル、POEセチルエーテル、POEステアリルエーテル、POEベヘニルエーテル、POEオレイルエーテル等が挙げられる。その含有量は0.1〜10.0重量%、好ましくは2.0〜6.0重量%である。0.1重量%未満であると分離等、剤の経時的安定性に影響があり、10.0重量%を超えると剤の粘度が高くなり、圧縮ガス等による容器からの吐出が困難になるため、吐出量にムラが生じ、第一剤と第二剤とを所定の吐出量の比率にて同時に吐出することが困難になる。又、非イオン性界面活性剤は異なる2種以上を含有することが好ましく、1種はHLB値9.0未満、他の1種はHLB値13.0以上であることが好ましい。 Among these, POE alkyl ethers, POE alkylphenyl ethers, POE / POP alkyl ethers, and POE sorbitan fatty acid esters are preferable because they are resistant to acids and alkaline agents, and among these, POE alkyl ethers are particularly preferable. .. Specific examples of POE alkyl ethers include POE lauryl ether, POE cetyl ether, POE stearyl ether, POE behenyl ether, POE oleyl ether and the like. Its content is 0.1 to 10.0% by weight, preferably 2.0 to 6.0% by weight. If it is less than 0.1% by weight, the stability of the agent over time such as separation will be affected, and if it exceeds 10.0% by weight, the viscosity of the agent will increase and it will be difficult to discharge the agent from the container with compressed gas or the like. Therefore, the discharge amount becomes uneven, and it becomes difficult to simultaneously discharge the first agent and the second agent at a predetermined discharge amount ratio. Further, the nonionic surfactant preferably contains two or more different types, one having an HLB value of less than 9.0, and the other having an HLB value of 13.0 or more.

尚、HLBとは、親水性−親油性のバランス(Hydrophile−Lipophile Balance)を示す指標であり、本発明においては、小田・寺村らによる次式を用いて算出した値を用いた。
HLB={(Σ無機性値)/(Σ有機性値)}×10
The HLB is an index showing a hydrophilic-lipophilic balance (Hydrophile-lipophilic Balance), and in the present invention, a value calculated by using the following formula by Oda and Teramura et al. Was used.
HLB = {(Σ inorganic value) / (Σ organic value)} × 10

本発明の二剤同時吐出型染毛剤には炭化水素を適宜配合することが可能である。炭化水素としては、例えば、α−オレフィンオリゴマー、流動パラフィン、軽質イソパラフィン、軽質流動イソパラフィン、流動イソパラフィン、ワセリン、ポリエチレン末、オゾケライト、ポリブテン、セレシン等が挙げられる。これらの中でも特に安定性の点から、流動パラフィン、軽質イソパラフィン、軽質流動イソパラフィン、流動イソパラフィンが好ましい。その含有量は0.1〜20.0重量%、好ましくは2.0〜15.0重量%である。0.1重量%未満であると分離等、剤の経時的安定性に影響があり、20.0重量%を超えると剤の粘度が高くなり、圧縮ガス等による容器からの吐出が困難になるため、吐出量にムラが生じ、第一剤と第二剤とを所定の吐出量の比率にて同時に吐出することが困難になる。 Hydrocarbons can be appropriately added to the two-agent simultaneous discharge type hair dye of the present invention. Examples of hydrocarbons include α-olefin oligomers, liquid paraffins, light isoparaffins, light liquid isoparaffins, liquid isoparaffins, petrolatum, polyethylene powder, ozokelite, polybutene, selecin and the like. Of these, liquid paraffin, light isoparaffin, light liquid isoparaffin and liquid isoparaffin are preferred from the standpoint of stability. Its content is 0.1 to 20.0% by weight, preferably 2.0 to 15.0% by weight. If it is less than 0.1% by weight, the stability of the agent over time such as separation will be affected, and if it exceeds 20.0% by weight, the viscosity of the agent will increase and it will be difficult to discharge the agent from the container with compressed gas or the like. Therefore, the discharge amount becomes uneven, and it becomes difficult to simultaneously discharge the first agent and the second agent at a predetermined discharge amount ratio.
