Here, the average particle diameter can be measured as a volume average particle diameter using, for example, Multisizer ^™ 4 manufactured by Beckman Coulter, which is a particle size distribution measuring apparatus. It is desirable to perform the measurement at room temperature (15 to 30 ° C.).

Next, each process in the manufacturing method of a vesicle composition is demonstrated more concretely.
The vesicle composition of the present invention preferably takes the form of a vesicle dispersion (premix). This vesicle dispersion is, for example, in the following stages:
(I) a step of dissolving the oil phase containing the component (A), the component (B), and the component (C) at a temperature equal to or higher than the melting point of the oil phase;
(Ii) mixing while adding an aqueous phase to the oil phase obtained in step (i) above;
Can be suitably manufactured. According to such a procedure, a vesicle composition in which the continuous phase is an aqueous phase is obtained.

First, in step (i), the oil phase needs to be dissolved from the viewpoint of stable production. For this reason, it is preferable to melt | dissolve at the temperature more than melting | fusing point of an oil phase, and also melt | dissolve at the temperature higher 5 degreeC or more than the melting | fusing point of an oil phase, and it is preferable to melt | dissolve especially 10 degreeC or more higher than the melting point of an oil phase.
The oil phase is preferably in a uniformly mixed state. Therefore, in this step, it is preferable to dissolve the oil phase while mixing. The mixing method is not particularly limited, but for example, it is preferable to mix by stirring.

  Next, in the step (ii), the aqueous phase is dropped into the oil phase dissolved in the step (i), specifically, the oil phase in a sheared mixed state. The mixing apparatus is not particularly limited as long as shear mixing can be performed. However, when the viscosity becomes high during the addition of the aqueous phase, an apparatus capable of mixing a high-viscosity product, for example, ADI homomixer manufactured by Primix Co., Ltd. K. A combination mix, a vacuum emulsification stirrer manufactured by Mizuho Industry Co., Ltd., a Max blend stirrer tank manufactured by Sumitomo Heavy Industries, Ltd., a supermix stirrer tank manufactured by Satake Chemical Machinery Co., Ltd. are preferable.

  In the step (ii), the mixing is performed so that the maximum value of the stirring required power Pv falls within the specific range described above. Thereby, while suppressing mixing of lamellar lamella etc. and forming a vesicle structure efficiently, the performance of the hair cosmetics obtained using a vesicle composition can be improved stably.

  Here, Pv generally indicates the mixing property of the liquid in the compounding tank, which is determined by the shape factor of the compounding tank and the stirring blade, the rotational speed of the stirring blade, the density, volume and viscosity of the liquid in the mixing tank. It is an index to evaluate.

In the present invention, the maximum value of Pv in step (ii) is set to 0.1 kW / m ³ or more. As a result, the mixing properties of the oil phase and the aqueous phase are improved, and mixing can be performed in a state where the vesicle volume concentration (volume ratio of vesicles in the dispersion) and the viscosity of the dispersion are preferably balanced. Formation of layered lamellae and the like can be suppressed, and a vesicle structure can be obtained efficiently. Further from the viewpoint of efficiently producing vesicles, the maximum value of Pv in the step (ii) is preferably 0.5 kw / m ³ or more, further preferably 1.5 kw / m ³ or more.

On the other hand, by setting the maximum value of Pv to 10 kw / m ³ or less, when blending the vesicle composition into the hair cosmetic composition, while preventing the stickiness after rinsing and stickiness after drying, Smoothness can be improved particularly stably. This reason is presumed to be related to the fact that when the maximum value of Pv is too large, the moisture content in the vesicle is excessively decreased. From the viewpoint of further improving the smoothness of hair cosmetics containing the vesicle composition from the time of rinsing to after drying, and further improving the production stability of industrial vesicles, the maximum value of Pv in step (ii) preferably at 7 kw / m ³ or less, further preferably 5 kw / m ³ or less.

  In the step (ii), the factors that control the maximum value of Pv include the shape factor of the mixing tank and the stirring blade, the rotational speed of the stirring blade, the dripping time of the aqueous phase, the density, volume, and viscosity of the liquid in the mixing tank. Can be mentioned. Among these, from the viewpoint of easily controlling the maximum value of Pv, it is preferable to control the maximum value of Pv by the rotation speed of the stirring blade and the dropping time of the aqueous phase. The maximum value of Pv can be increased by increasing the rotational speed of the stirring blade, for example. The rotation speed of the stirring blade is preferably 15 to 800 rpm, for example.

  Also, the maximum value of Pv can be increased by lengthening the dropping time of the aqueous phase. For example, the dropping time is preferably 5 minutes or more and 20 minutes or more, preferably 100 minutes or less, and preferably 80 minutes or less.

  By increasing the rotation speed (number of rotations) of the stirring blade or increasing the dropping time of the aqueous phase, the mixing property of the oil phase and the aqueous phase is improved, and the maximum value of Pv is increased. The generation efficiency of is increased. On the other hand, if the rotation speed (number of rotations) of the stirring blade is too large or the dripping time of the aqueous phase is too long, the water content in the vesicles will be too low, and when blended into the hair cosmetic, Performance may not be fully demonstrated. For this reason, in the step (ii), the mixing condition is set so that the maximum value of Pv falls within the specific range described above.

  In step (ii), Pv can be measured using, for example, a clamp wattmeter manufactured by Hioki Electric Co., Ltd. From the viewpoint of simply calculating the maximum Pv value, it is desirable to actually measure the power.

When Pv is actually measured, as shown in the following formula (II), it can be calculated by dividing the net stirring power obtained by subtracting the stirring power during idling from the measured stirring power by the amount of liquid in the blending tank at that time. .
Pv = (Pi−P0) / V (II)
(In the above formula (II), Pi is the actually measured stirring power [kW], P0 is the stirring power [kW] during idling, and V is the volume of the liquid in the blending tank [m] ³ ].)

In addition, the control of the structure by the Pv value can be controlled more precisely as the total amount charged into the blending tank is larger. In addition, the Pv value itself can be controlled more accurately as the total amount charged into the blending tank is larger.
Therefore, from the viewpoint of improving the controllability of the maximum value of Pv, it is preferable to carry out phase inversion emulsification by mixing the total weight of the oil phase and the aqueous phase charged into the compounding tank as 10 kg or more, more preferably 100 kg or more, More preferably, it is 200 kg or more.

Furthermore, when controlling the particle size of a vesicle, it can adjust with the stirring rotation speed after the water phase dripping start. From the viewpoint of obtaining a vesicle having a particle size that further improves the smoothness from the time of rinsing to the time of drying while suppressing the stickiness at the time of rinsing and the stickiness after the drying, the stirring rotation speed after the start of dropping of the aqueous phase is 15 to 800 rpm is preferred.
In addition, from the viewpoint of stably improving the smoothness from rinsing to after drying, while suppressing the stickiness at the time of rinsing and the stickiness after drying in the hair cosmetic containing the vesicle composition, the vesicle in the vesicle dispersion The volume concentration of is preferably higher. The volume concentration of the vesicle in the vesicle dispersion can be adjusted by the dropping speed of the aqueous phase to the oil phase and the number of rotations of stirring during the dropping of the aqueous phase. The optimum value of the dropping speed of the water phase to the oil phase and the stirring rotation speed at the time of dropping varies depending on the prescription of the vesicle composition, the component ratio, the size and shape of the blending tank, but the most viscous during the dropping of the aqueous phase. Conditions that allow uniform mixing in the ascending state are preferred. As the aqueous phase is further dropped, the viscosity of the vesicle dispersion decreases and the vesicle volume concentration decreases. The amount of the aqueous phase to be dropped can be appropriately adjusted in consideration of the storage stability and handling properties of the vesicle dispersion.
The dropping speed of the aqueous phase to the oil phase can be appropriately selected as described above, but for the purpose of increasing the volume concentration of the vesicle in the vesicle dispersion, the dropping speed is not particularly limited, but takes 5 minutes or more. It is desirable to drop it.

  In step (ii), the temperature at the time of dropping the aqueous phase can be appropriately determined by the oil phase temperature, the temperature of the dropping water phase and the heating or cooling in the mixing device. The gel transition temperature of the vesicle to be formed is preferably higher than the gel transition temperature. The emulsification method in which the water phase is dropped while stirring the oil phase is generally referred to as phase inversion emulsification. In the present invention, the vesicle composition is excellent in handling properties by constituting the oil phase as described above and forming the vesicle composition by phase inversion emulsification.

  Here, purified water such as ion-exchanged water or distilled water is used for the “aqueous phase”. As will be described later, a polyhydric alcohol that is a component (D) dissolved in water, such as glycerin and dipropylene glycol, etc. Can also be included.

In addition, from the viewpoint of the stability of the obtained vesicle composition, the method for producing a vesicle composition comprising a step of (iii) a step of (iii) a step of rapidly cooling to the gel transition temperature of the vesicle after the completion of dropping of the aqueous phase. It is preferable that

In the method for producing a vesicle composition, the oil phase may further contain a component (D) a polyhydric alcohol.

Specific examples of the component (D) include ethylene glycol, diethylene glycol, propylene glycol, dipropylene glycol, and glycerin. In particular, propylene glycol and dipropylene glycol are preferable.

  The content of the component (D) is preferably 0.5 to 60% by mass and more preferably 1 to 50% by mass with respect to the entire vesicle composition from the viewpoint of storage stability of the vesicle composition. 2-20 mass% is especially preferable.

  When component (D) is blended in the vesicle composition, it can be added to the aqueous phase at the stage of step (ii) as described above, but it is preferably added to the oil phase in step (i). In step (i), the oil phase containing component (A), component (B), and component (C) is dissolved at a temperature equal to or higher than the melting point of the oil phase, and then component (D) is added to the oil phase. Is preferred. Alternatively, in the step (i), the oil phase containing the component (A), the component (B), the component (C), and the component (D) was dissolved at a temperature equal to or higher than the melting point of the oil phase until no solid matter disappeared. An oil phase may be obtained. After step (i), a vesicle dispersion having a high vesicle volume concentration and high storage stability can be obtained by passing through the step (ii) of mixing while adding an aqueous phase to the obtained oil phase. it can. Further, from the viewpoint of storage stability of the vesicle, it is preferable to pass through the step (iii) of quickly cooling the vesicle to a gel transition temperature or lower after the completion of the dropwise addition of the aqueous phase.

  In the step (i), an optional component can be added to the oil phase as long as the production of the vesicle of the present invention is not inhibited. Examples of the optional component include various extracts and antioxidants, but are not limited thereto. The optional component that can be added to the oil phase is, for example, 1% by mass or less of the oil phase from the viewpoint of producing a stable vesicle composition.

  In the step (ii), any component can be added to the aqueous phase as long as the production of the vesicle of the present invention is not inhibited. Examples of optional components that can be added include various extracts and preservatives, but are not limited thereto.

  As for the higher alcohol, the vesicle composition is used from the viewpoint of increasing the volume ratio of the vesicle contained in the composition in the prescription including the components (A), (B) and (C) as in the present embodiment. It is better not to contain or substantially not to contain it, and it is preferably 2% by mass or less, particularly preferably 1% by mass or less in the vesicle composition.

It is preferable that the quantity which becomes 0.05-2 mass% more preferably is mentioned.

Examples of such hair cosmetics include conditioners, rinses, treatments, and shampoos. Conditioners, rinses, and treatments are particularly preferred as effective hair cosmetics. These hair cosmetics may be used after washing hair cosmetic or after use.
