Dextrin fatty acid esters are commercially available, and examples thereof include Leopard MKL2, Leopard TL2, Leopard TT2, Unifilm Mar HVY (above, manufactured by Chiba Flour Milling Co., Ltd.). The dextrin fatty acid ester may contain one of the dextrin fatty acid esters described above alone or in combination of two or more.
デキストリン脂肪酸エステルは、透明ゲル状油性組成物全質量に対して、３質量％以上３０質量％以下含有されるのが好ましく、デキストリン脂肪酸エステルが前記範囲内で含有されると、貯蔵弾性率及び損失弾性率を後述する特定の範囲に調整し易い。 The dextrin fatty acid ester is preferably contained in an amount of 3% by mass or more and 30% by mass or less with respect to the total mass of the transparent gelled oily composition. It is easy to adjust the elastic modulus to a specific range described later.
透明ゲル状油性組成物中には、本発明の効果を損なわない範囲で前述した油性成分及びデキストリン脂肪酸エステル以外の任意成分を含有することができる。任意成分としては、例えば、油溶性ビタミン等の油溶性薬効成分、紫外線吸収剤、防腐剤、抗酸化剤、香料、色材等の油溶性成分が挙げられる。透明ゲル状油性組成物は、油性成分とデキストリン脂肪酸エステルと必要に応じて含有される任意成分との合計が１００質量％になるように含有される。 The transparent gel-like oily composition can contain optional components other than the oily component and dextrin fatty acid ester described above within a range not impairing the effects of the present invention. Examples of optional components include oil-soluble medicinal components such as oil-soluble vitamins, and oil-soluble components such as ultraviolet absorbers, preservatives, antioxidants, fragrances, and coloring materials. The transparent gel-like oily composition is contained so that the total of the oily component, the dextrin fatty acid ester and the optional component contained as necessary becomes 100% by mass.
また、前記外相は、前記透明ゲル状油性組成物の７５℃での貯蔵弾性率が１，０００Ｐａ以下であり、かつ前記透明ゲル状油性組成物の２５℃での損失弾性率が１５０Ｐａ以上である。 Further, the external phase has a storage elastic modulus at 75 ° C. of the transparent gel-like oily composition of 1,000 Pa or less, and a loss elastic modulus at 25 ° C. of the transparent gel-like oily composition of 150 Pa or more. .
貯蔵弾性率は、弾性を表すパラメータであり、透明ゲル状油性組成物の７５℃での貯蔵弾性率が１，０００Ｐａ以下であると、後述するように外相中に充填ノズルを用いて内相となる可視組成物を分散させて立体模様を描く際に、立体模様のデザインを保持することができ、美しい立体模様が形成され、視覚的に美しい化粧料を提供することができる。透明ゲル状油性組成物の７５℃での貯蔵弾性率が１，０００Ｐａを超えると、外相中で充填ノズルを動かしたときに、充填ノズルの移動跡が残ってしまい、想定した立体模様を描くのが困難である。なお、７５℃での貯蔵弾性率が１，０００Ｐａ以下であれば充填可能であり、貯蔵弾性率は０より大きければよい。 The storage elastic modulus is a parameter representing elasticity, and when the storage elastic modulus at 75 ° C. of the transparent gel-like oily composition is 1,000 Pa or less, as described later, the inner phase is filled with a filling nozzle in the outer phase. When a three-dimensional pattern is drawn by dispersing the visible composition, a three-dimensional pattern design can be maintained, a beautiful three-dimensional pattern is formed, and a visually beautiful cosmetic can be provided. When the storage elastic modulus at 75 ° C. of the transparent gel-like oily composition exceeds 1,000 Pa, when the filling nozzle is moved in the outer phase, the movement trace of the filling nozzle remains, and the assumed three-dimensional pattern is drawn. Is difficult. In addition, it can be filled if the storage elastic modulus in 75 degreeC is 1,000 Pa or less, and the storage elastic modulus should just be larger than zero.
損失弾性率は、粘性を表すパラメータであり、透明ゲル油性組成物の２５℃での損失弾性率が１５０Ｐａ以上であると、充填ノズルを用いて分散させた可視組成物のデザインを長期間にわたって保持することができる。したがって、経時安定性の良好な化粧料を提供することができる。透明ゲル油性組成物の２５℃での損失弾性率が１５０Ｐａ未満であると、時間の経過と共に立体模様が崩れるおそれがある。また、透明ゲル油性組成物の２５℃での損失弾性率は、使用性の観点から１５，０００Ｐａ未満であるのが好ましい。 Loss elastic modulus is a parameter representing viscosity. When the loss elastic modulus at 25 ° C. of the transparent gel oil composition is 150 Pa or more, the design of the visible composition dispersed using a filling nozzle is maintained for a long period of time. can do. Therefore, it is possible to provide a cosmetic material with good temporal stability. If the loss elastic modulus at 25 ° C. of the transparent gel oil-based composition is less than 150 Pa, the three-dimensional pattern may be destroyed over time. Moreover, it is preferable that the loss elastic modulus in 25 degreeC of a transparent gel oil-based composition is less than 15,000 Pa from a viewpoint of usability.
前記透明ゲル状油性組成物の７５℃での貯蔵弾性率及び２５℃での損失弾性率は、誘電分散粘弾性測定装置（例えば、ティー・エイ・インスツルメント・ジャパン株式会社製）を用いて次のように測定することができる。直径５０ｍｍのパラレルプレートに透明ゲル状油性組成物の検体を約１ｍｍの厚さに乗せて、上下のパラレルプレートで挟み、ひずみ５％、振動１Ｈｚの条件にて、２５℃から８０℃まで３℃／分の速度で昇温させて、７５℃での貯蔵弾性率と２５℃での損失弾性率とを測定する。 The storage elastic modulus at 75 ° C. and the loss elastic modulus at 25 ° C. of the transparent gel oily composition are measured using a dielectric dispersion viscoelasticity measuring device (for example, manufactured by T.A. Instruments Japan Co., Ltd.). It can be measured as follows. A transparent gel oil composition specimen is placed on a parallel plate with a diameter of 50 mm on a thickness of about 1 mm, and is sandwiched between upper and lower parallel plates. The temperature is 3 ° C. from 25 ° C. to 80 ° C. under the conditions of 5% strain and 1 Hz vibration. The temperature is raised at a rate of / min, and the storage elastic modulus at 75 ° C. and the loss elastic modulus at 25 ° C. are measured.
前記透明ゲル状油性組成物の７５℃での貯蔵弾性率と２５℃での損失弾性率とは、油性成分とデキストリン脂肪酸エステルとの配合量、デキストリン脂肪酸エステルの種類等を変更することにより調製することができる。 The storage elastic modulus at 75 ° C. and the loss elastic modulus at 25 ° C. of the transparent gel oily composition are prepared by changing the blending amount of the oil component and dextrin fatty acid ester, the type of dextrin fatty acid ester, and the like. be able to.
前記透明ゲル状油性組成物は、油性成分とデキストリン脂肪酸エステルと必要に応じて含有される任意成分とを混合、撹拌することによって調製することができる。 The transparent gel-like oily composition can be prepared by mixing and stirring an oily component, a dextrin fatty acid ester, and an optional component contained as necessary.
次に、この発明の化粧料における内相について説明する。内相は、２５℃での粘度が２，０００ｍＰａ・ｓ以上３０，０００ｍＰａ・ｓ以下の範囲にある可視組成物であるのが好ましい。前記可視組成物の粘度が２，０００ｍＰａ・ｓ未満であると、時間の経過と共に内相のデザイン形状が保てず、立体模様が崩れる場合があり、前記可視組成物の粘度が３０，０００ｍＰａ・ｓを超えると、充填速度によっては、充填ノズルを用いて外相中に立体模様を形成し難くなって美しいデザインが形成されない場合がある。すなわち、後述するように外相中に充填ノズルを用いて可視組成物を分散させて立体模様を描く際に、前記可視組成物の粘度が前記範囲内にあると、前記可視組成物の粘度が前記範囲外にある場合よりも充填速度の選択幅が広くなり、生産性を向上するために充填速度を速くしても立体模様を形成することができ、また、その立体模様は、より長期間にわたって安定して保持される。前記可視組成物の粘度が前記範囲外にある場合、前記範囲内にあるときよりも、充填速度の選択幅が狭く、遅い速度でしか充填できず、必要な生産性が得られない場合がある。 Next, the inner phase in the cosmetic of the present invention will be described. The internal phase is preferably a visible composition having a viscosity at 25 ° C. in the range of 2,000 mPa · s to 30,000 mPa · s. If the viscosity of the visible composition is less than 2,000 mPa · s, the design shape of the inner phase may not be maintained with the passage of time, and the three-dimensional pattern may be destroyed, and the viscosity of the visible composition is 30,000 mPa · s. When s is exceeded, depending on the filling speed, it may be difficult to form a three-dimensional pattern in the outer phase using a filling nozzle, and a beautiful design may not be formed. That is, as will be described later, when the visible composition is dispersed in the outer phase using a filling nozzle to draw a three-dimensional pattern, when the viscosity of the visible composition is within the range, the viscosity of the visible composition is The choice of filling speed is wider than when it is out of the range, and a three-dimensional pattern can be formed even if the filling speed is increased in order to improve productivity. It is held stably. When the viscosity of the visible composition is outside the range, the selection rate of the filling speed is narrower than when the viscosity is within the range, and the filling can be performed only at a slow speed, and the required productivity may not be obtained. .
さらに内相は、７５℃での貯蔵弾性率が１，０００Ｐａ以下であり、かつ２５℃での損失弾性率が１５０Ｐａ以上である油性可視組成物であるが好ましい。前記油性可視組成物の７５℃での貯蔵弾性率が１，０００Ｐａを超えると、充填速度によっては、充填ノズルを用いて外相中に立体模様を形成し難くなって美しいデザインが形成されない場合があり、前記油性可視組成物の２５℃での損失弾性率が１５０Ｐａ未満であると、時間の経過と共に内相のデザイン形状が保てず、立体模様が崩れる場合がある。すなわち、後述するように外相中に充填ノズルを用いて可視組成物を分散させて立体模様を描く際に、前記油性可視組成物の貯蔵弾性率及び損失弾性率が前記範囲内であると、前記油性可視組成物の貯蔵弾性率および損失弾性率が前記範囲外にある場合よりも充填速度の選択幅が広くなり、生産性を向上するために充填速度を速くしても立体模様を形成することができ、また、その立体模様は、より長期間にわたって安定して保持される。前記油性可視組成物の貯蔵弾性率および損失弾性率が前記範囲外にある場合、前記範囲内にあるときよりも、充填速度の選択幅が狭く、遅い速度でしか充填できず、必要な生産性が得られない場合がある。 Further, the internal phase is preferably an oily visible composition having a storage elastic modulus at 75 ° C. of 1,000 Pa or less and a loss elastic modulus at 25 ° C. of 150 Pa or more. When the storage elastic modulus at 75 ° C. of the oily visible composition exceeds 1,000 Pa, depending on the filling speed, it may be difficult to form a three-dimensional pattern in the outer phase using a filling nozzle, and a beautiful design may not be formed. When the lossy elastic modulus at 25 ° C. of the oily visible composition is less than 150 Pa, the design shape of the inner phase cannot be maintained over time, and the three-dimensional pattern may collapse. That is, when the three-dimensional pattern is drawn by dispersing the visible composition using a filling nozzle in the outer phase as described later, the storage elastic modulus and loss elastic modulus of the oily visible composition are within the above range. The selection rate of the filling speed is wider than when the storage elastic modulus and loss elastic modulus of the oily visible composition are outside the above ranges, and a three-dimensional pattern is formed even if the filling speed is increased in order to improve productivity. In addition, the three-dimensional pattern is stably maintained for a longer period of time. When the storage elastic modulus and loss elastic modulus of the oily visible composition are out of the above range, the selection range of the filling speed is narrower than when the oily visible composition is within the above range, and the filling can be performed only at a low speed, and the required productivity. May not be obtained.
したがって、前述のような貯蔵弾性率及び損失弾性率の条件を満たす外相中に内相が立体模様状態で分散されることにより視覚的な美しさを有し、その立体模様の経時安定性を向上できるという効果を、内相を上記のような粘度の可視組成物、又は、貯蔵弾性率及び損失弾性率の油性可視組成物にすることで、より確実に得ることができる。さらに、内相を上記のような粘度、かつ、貯蔵弾性率及び損失弾性率の油性可視組成物とすれば、一層確実に本発明の効果を得ることができる。 Therefore, the inner phase is dispersed in a three-dimensional pattern state in the outer phase that satisfies the conditions of the storage elastic modulus and the loss elastic modulus as described above, thereby improving the temporal stability of the three-dimensional pattern. The effect of being able to be obtained can be more reliably obtained by making the internal phase into a visible composition having the above-mentioned viscosity or an oily visible composition having a storage elastic modulus and a loss elastic modulus. Furthermore, if the internal phase is an oily visible composition having the above-described viscosity, storage modulus and loss modulus, the effects of the present invention can be obtained more reliably.

The storage elastic modulus and loss elastic modulus of the visible composition can be measured using a dielectric dispersion viscoelasticity measuring apparatus in the same manner as in the transparent gel oil composition. Moreover, the viscosity, storage elastic modulus, and loss elastic modulus of the visible composition are adjusted according to the dosage form of the visible composition to be described later.

It can also be obtained. In addition, when the inner phase is aqueous, by blending a water-soluble component that cannot be blended with the oily outer phase into the inner phase, for example, by blending a water-soluble whitening component such as vitamin C. A skin care effect can be obtained, and a higher makeup effect and the like can be obtained by adding more pigments. For this reason, for example, it can be suitably used for makeup cosmetics such as under make-up and lip gloss, skin care cosmetics such as massage creams, packs, essence creams, and eye creams, and hair care cosmetics such as hair waxes. Moreover, it can apply not only to these cosmetics but to various cosmetics.
