Description

Technical Field

[0001] The present invention relates to solid cosmetics. Further, in the present invention, the composition for cosmetics may sometimes be referred to as cosmetics. Background Art

[0002] Since solid cosmetics contain solidifying components such as wax, good usability is required. In particular, in the case of lip cosmetics, glossiness and adhesiveness are further required. In order to impart glossiness and adhesiveness, a method of combining phenyl silicone, highly polymerized hydrocarbon oil, ester oil, etc. and solidifying with wax, etc. is known. However, components that easily achieve glossiness and adhesiveness tend to have poor compatibility. For example, a technique of creating an oil-in-oil state and solidifying with wax, etc. is known (Patent Document 1: Japanese Patent No. 5280490). In addition, in order to improve the transparency of wax, a technique of mixing a specified amount of phenyl-containing polysiloxane is known (Patent Document 2: Japanese Patent No. 6231748). However, these techniques are insufficient in terms of glossiness and adhesiveness.

[0006] Patent Document 2: Japanese Patent No. 6231748 Summary of the Invention

[0007] Problems to be Solved by the Invention

[0008] The present invention has been completed in view of the above actual situation, and an object thereof is to provide a solid cosmetic having excellent glossiness, adhesiveness, usability, and storage stability.

[0009] Means for Solving the Problems

[0010] Phenyl silicone having excellent glossiness and hydrogenated polyisobutene having excellent adhesiveness are difficult to compatibilize due to their molecular weight and structure, and further have low compatibility with other oil agents. In the case of a solid cosmetic composed of oil agents having high compatibility, improvement in usability and storage stability is expected by homogenizing the wax structure in the oil agent. The present inventors have found that by combining a specific phenyl silicone having excellent glossiness, hydrogenated polyisobutene having excellent adhesiveness dissolved therein, and a specific compound, the above problems can be solved, and the present invention has been completed.

[0011] Therefore, the present invention provides the following solid cosmetic.

[0087] When the blended oils described in Table 2 were mixed at a mass ratio of each component of 1:1 (1:1:1), heated and mixed at 85°C, and then allowed to stand at 25°C for 1 hour, a state without boundaries and transparent to translucent was recorded as "dissolved", and a state of turbidity or separation into two layers was recorded as "not dissolved". The case of "dissolved" was recorded as "◎", and the case of "not dissolved" was recorded as "×".

[0088] [Examples 1 to 10, Comparative Examples 1 to 5]

[0089] After uniformly mixing the components shown in Tables 3 and 4 at 95°C, they were cooled to obtain a solid cosmetic.

[0090] The following evaluations were performed on the obtained solid cosmetic. The results are also shown in the table. It should be noted that the compounding amounts are the compounding amounts of the compounded products described.

[0091] (1) Property Evaluation

[0092] For the solid cosmetics of the following Examples and Comparative Examples, based on the evaluation criteria shown in Table 1, a panel of 10 members evaluated the glossiness (good finish), adhesion (good adhesion during coating), and usability (not rough, good elongation). Based on the average value of 10 people, the results were judged according to the following judgment criteria.

[0093] [Table 1]

[0094] Project Glossiness Sealing property Usability 5 points Good Good Good 4 points Slightly better Slightly better Slightly better 3 points Medium Medium Medium 2 points Slightly worse Slightly worse Slightly worse 1 point Bad Bad Bad

[0095] (2) Judgment criteria

[0096] ◎: The average score is 4.5 or more.

[0097] ○: The average score is more than 3.5 and less than 4.5.

[0098] △: The average score is more than 2.5 and less than 3.5.

[0099] ×: The average score is more than 1.5 and less than 2.5.

[0100] ××: The average score is less than 1.5.

[0101] Those with △ or above are recorded as qualified.

[0102] (3) Storage stability

[0103] The solid cosmetics were filled in 30 mL vials and stored in a constant temperature bath at 50 °C for 1 month. Then, the properties were observed with the naked eye and applied to the skin to examine the touch. As a result, the case where there were no problems such as separation, sweating, and change in touch was recorded as "◎", and the case with problems was recorded as "×".

[0108] [Table 3]

[0109]

[0110] [Table 4]

[0111]

[0112] As can be seen from the above results, the glossiness (good finishing property), adhesion (good adhesiveness during coating), usability (not rough, good extensibility), and storage stability (50°C for 1 month) of the solid cosmetics of Examples 1 to 10 are good.

[0113] For Comparative Example 1 in which the component (b) is dissolved with the component (a) but does not contain the component (c), and Comparative Example 2 which contains the component (e) of phenyl silicone as an ingredient other than the component (a) and is not dissolved with the component (b), the usability and storage stability are not satisfactory. For Comparative Example 3 in which the component (e) is dissolved with the component (b) but does not contain the component (c), and Comparative Example 4 which does not contain the component (b), sufficient glossiness and adhesion are not obtained. For Comparative Example 5 in which the hydrogenated polyisobutene is not dissolved with the component (a) and does not contain the component (c), the usability and storage stability are not satisfactory.

[0114] The following examples are combinations in which the component (a) and the component (b) are dissolved when mixed, combinations in which the component (a), the component (b), and the component (c) are dissolved when mixed, and combinations in which the component (a), the component (b), the component (c), and the component (e) are dissolved when the component (e) is compounded. It should be noted that the compounding amount is the compounding amount of the recorded compounded product, and the total amount of the component (a) and the total amount of the component (b) are the amounts of the pure components.
