Description

  The present invention relates to a method for producing a skin cosmetic.

  As skin cosmetics, various cosmetics using water-swellable clay minerals have been shown (for example, Patent Documents 1 to 4) because they are excellent in the smooth feeling of the skin during use. Such a skin cosmetic is generally obtained by dispersing and modifying a water-swellable clay mineral in an oil phase containing a lipophilic component, polyoxyethylene silicone, nonionic surfactant, polyhydric alcohol and the like. It is manufactured by dispersing in a water-soluble solvent or water.

However, water-swellable clay minerals have different viscosities depending on the product lot, so when manufactured using water-swellable clay minerals, it is difficult to keep the product viscosity of skin cosmetics small. Is difficult. As a method of suppressing the product viscosity fluctuation in such skin cosmetics, a method of increasing the mixing ratio of the polyhydric alcohol to the water-swellable clay mineral is conceivable. However, in this method, the liquid stability of the product is deteriorated and the aqueous phase and the oil phase are easily separated, and long-term storage becomes difficult.
In addition, since polyhydric alcohol is also a moisturizing component, it is preferable that the blending amount thereof is as large as possible in skin cosmetics. However, it is difficult to increase the blending amount for the above reasons.

[Production method]
The production method of the present invention is a method for producing the above-described skin cosmetic, wherein (A) component, (B) component, (C) component, and (D) component mixing step (1) and step (1) ) Is followed by a step (2) in which the remainder of the component (D), the component (E) and water are further added and mixed.

In step (1), components (A) to (D) are mixed. Component (D) in the step (1) may use some or all of the total amount to be contained in skin cosmetics, (A) component and the mass M A of the (D) mass ratio of the mass M D of the component ( M D / M A ) is 4 to 8, preferably 5 to 7. If the mass ratio (M D / M A ) is 4 or more, the difference in viscosity depending on the lot of the component (A) to be used can reduce the effect on the viscosity of the obtained skin cosmetic, and the equivalent viscosity can be reduced. It is possible to stably produce a skin cosmetic composition. Further, if the mass ratio (M D / M A) is 8 or less, good skin cosmetics in liquid stability.

The mixing method of each component in a process (1) will not be specifically limited if it can mix until the component to mix until it becomes uniform enough, Various stirrers can be used. For example, Ajihomo mixer (HV-M type, manufactured by Plymix Co., Ltd.) or the like can be used.
The mixing temperature in the step (1) is preferably 20 to 60 ° C, more preferably 20 to 50 ° C, and more preferably 30 to 50 ° C. If mixing temperature is 20 degreeC or more, mixing of each component will become easy. Further, if the mixing temperature is 60 ° C. or lower, the skin cosmetics having the same viscosity can be easily obtained because the viscosity of the skin cosmetics due to the difference in the viscosity of the component (A) becomes small.

In the step (1), if the mass ratio (M D / M A ) between the component (A) and the component (D) is 4 to 8, the order of mixing the components (A) to (D) is particularly It is not limited. For example, it may be a method of adding and mixing all of the components (A) to (D) at the same time. The components (A) and (D) are mixed, and the components (B) and (C) are mixed there. It may be a method of adding and mixing, or a method of adding and mixing the component (D) to a mixture of the components (A) to (C). However, when using 2 or more types of (C) component, it is preferable to pre-mix these (C) components. This makes it easier to obtain a skin cosmetic of the same quality with a low viscosity flare.

In the step (2), the remainder of the component (D), the component (E), and water are added to and mixed with the liquid mixture obtained in the step (1). That is, when the total amount of the component (D) is mixed in the step (1), only the component (E) and water are mixed, and the part of the component (D) to be contained in the skin cosmetic in the step (1) is mixed. (D) A component, (E) component, and water are mixed.
The mixing method in process (2) should just be a method which can mix each component fully uniformly, and can be performed with the same stirrer as process (1).

In step (2), the component (E) is added and mixed simultaneously with water, or added and mixed after adding and mixing water. Thereby, it can prevent that the viscosity of a liquid mixture raises rapidly and the viscosity of skin cosmetics becomes high too much. The order of addition and mixing of the component (D), water and the component (E) in the step (2) is not particularly limited.
Moreover, when mix | blending an arbitrary component with skin cosmetics, in the process (2) from the point of not inhibiting the interaction of (A)-(D) component in a process (1), or the point of efficiency of mixing. It is preferable to add.

The production method of the present invention suppresses the flare of the product viscosity of the skin cosmetic due to the difference in the viscosity of each lot of the component (A). The viscosity of the component (A) is measured by the following method. 4% aqueous solution viscosity (unit: mPa · s).

A method for preparing a blended product (skin cosmetic) in the present example is shown below. In this example, a compounded product was prepared by the same method for each of lot 1 and lot 2 of compound (A-1). Hereinafter, the respective blended products obtained for each lot are referred to as “lot 1 blended product” and “lot 2 blended product”.
First, when a plurality of components (C) were used, the plurality of components (C) were premixed until uniform using a 45 ° inclined paddle.
Next, in step (1), (A) component, (B) component, (C) component and (D) component are added to Ajihomo mixer (HV-M type, manufactured by Primix Co., Ltd.), and the rotational speed is 80 rpm. For 10 minutes.
Next, in step (2), component (D) and water, or water alone (Comparative Examples 1 to 3) are added, stirred at a rotation speed of 80 rpm for 10 minutes with a paddle mixer, and further 10,000 rpm with a homomixer. For 45 seconds. Next, component (E) and an optional component were added, and the mixture was stirred for 10 minutes at a paddle mixer rotation speed of 80 rpm to obtain a blended product.
The blending amounts and mixing temperatures of the components in each step are as shown in Tables 1 and 2.

[Evaluation methods]
In this example, the blend viscosity viscosity shown below and the stability of the blend were evaluated for the lot 1 blend and the lot 2 blend of each example.
(Freight rate of compounded product)
For each of the lot 1 blended product and the lot 2 blended product in each example, the rotor used is the rotor No. 4, using a B-type viscometer M type (manufactured by Tokyo Keiki Co., Ltd.), the rotation speed is 30 rpm, the rotor rotation time is 20 seconds, and the measurement temperature Viscosity is measured under the condition of 20 ° C., and the viscosity of the blended product viscosity is calculated according to the following formula (I) from the viscosity of the lot 1 blended product (unit: mPa · s) and the viscosity of the lot 2 blended product (unit: mPa · s). The rate (unit:%) was calculated.
Z = (Y−X) / Y × 100 (I)
However, Z in Formula (I) is the flare rate of the blended product viscosity, X is the viscosity of the lot 1 blended product, and Y is the viscosity of the lot 2 blended product.

(Stability of compounded product)
Fill each 50 mL of the lot 1 blended product and lot 2 blended product obtained in each example into a vial with a diameter of 35 mm and a height of 50 mm, and leave the vial in a constant temperature bath at 50 ° C. for a certain period of time. It observed visually and evaluated by the following references | standards.
A: No separation occurred in the blended product after 3 months.
○: No separation occurred in the blended product after 2 months, and separation was observed after 3 months.
Δ: Separation did not occur in the blended product after 1 month, and separation was observed after 2 months.
X: Separation was observed in the blended product after one month.
Tables 1 and 2 show the viscosities of the blended products, the flare rate of the blended products, and the stability results in Examples and Comparative Examples.

As shown in Table 1 and Table 2, the blended products of Examples 1 to 20 produced by the production method of the present invention have a low flare rate of the blended product and have different 4% aqueous solution viscosities as component (A). Using any of Lot 2, a blended product having an equivalent viscosity was stably obtained. Moreover, the stability of the obtained blended product was also excellent.
When Examples 1, 11 and 12 are compared, the mixing temperature at which each component is mixed in Step (1) and Step (2) is 30 ° C. and 50 ° C. compared to 60 ° C. It was excellent. In addition, the blending temperature of the blended product in which the mixing temperature was 30 ° C. and 50 ° C. was lower than 60 ° C., the blended product viscosity was low, and the blended product having the same viscosity was obtained more stably.
Comparing Examples 1,2,5,9,10 and 13 to 18, towards the value of M D / M A in step (1) is 5 to 7 of the formulation products, the value of M D / M A The flare rate of the blended product viscosity was smaller than the blended products of 4 and 8.

On the other hand, prepared was Comparative Example 1 of mixed product as 0.27 the values of M D / M A (Example equivalent conditions of Patent Document 1) has a large inflation rate of mixed product viscosity, the compound used (A The viscosity of the blended product obtained by the lot of -1) varied.
Also in Comparative Example 2 in which the mixing temperature was set to 30 ° C. with the same blending amount as in Comparative Example 1, the flare rate of the blended product viscosity was large as in Comparative Example 1, and it was obtained depending on the lot of compound (A-1) to be used. There was variation in the viscosity of the blended product.
In Comparative Example 3 in which the blending amount of the component (D) in the step (1) was increased without using the component (E), the blend viscosity of the blended product was large, and the liquid stability of the obtained blended product was also high. It was inferior.
In Comparative Example 4 the values of M D / M A in step (1) is less than 4, although was excellent stability of mixed product in comparison with Comparative Example 3, in which the addition of component (E) Regardless, there was variation in the viscosity of the blended product obtained depending on the lot of compound (A-1) used.
In Comparative Example 5 in which the value of M D / M A in step (1) is more than 8, (E) Although inflation rate of mixed product viscosity by blending the components is reduced, the liquid stability of the mixed product was poor .
In Comparative Example 6 where the blending amount of the component (E) is small, the flare rate of the blended product viscosity is large, and the stability of the blended product is also poor.
In Comparative Example 7 in which the blending amount of the component (E) was large, the blended product viscosity was low, and the stability of the blended product was excellent, but the blended product viscosity was too large to be suitable for practical use.
