[0010] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the preferred embodiments. However, the present invention is not limited to the following embodiments, and various modifications can be made within the scope of the present invention.

[0011] <Oil-in-Water Emulsion Cosmetic Composition> The oil-in-water emulsion cosmetic composition of the present invention (hereinafter also simply referred to as "the composition of the present invention") may be an oil-in-water emulsion cosmetic composition comprising vitamin A or a derivative of vitamin A, a polar oil having no hydroxyl groups, and PEG-12 dimethicone, or an oil-in-water emulsion cosmetic composition comprising vitamin A or a derivative of vitamin A and a polar oil having no hydroxyl groups, wherein the polar oil having no hydroxyl groups comprises at least one selected from the group consisting of caprylic / capric triglyceride, diethylhexyl succinate, and diisobutyl adipate.

[0012] The composition of the present invention is excellent in stability and ease of use, whether it contains vitamin A or a derivative of vitamin A, a polar oil having no hydroxyl groups, and PEG-12 dimethicone, or whether it contains vitamin A or a derivative of vitamin A and a polar oil having no hydroxyl groups, and the polar oil having no hydroxyl groups includes at least one selected from the group consisting of caprylic / capric triglyceride, diethylhexyl succinate, and diisobutyl adipate.

[0013] Because vitamin A is unstable, it is conceivable to select, for example, a nonionic surfactant rather than an ionic surfactant when preparing an oil-in-water emulsion cosmetic composition containing vitamin A. However, through intensive research by the present inventors, it has been found that even when a nonionic surfactant is used, the vitamin A in the prepared composition may become unstable. Furthermore, it has been found that although vitamin A esters, which are derivatives of vitamin A, appear to be relatively stable compared to vitamin A, they may undergo, for example, hydrolysis or transesterification due to the influence of an oily medium used in combination, and as a result, the vitamin A esters may also become unstable.

[0014] Further, through intensive research, the present inventors investigated the type of polar oil to be blended into the composition and various nonionic surfactants. As a result, it was found that when a polar oil without a hydroxyl group is used in combination with PEG-12 dimethicone, vitamin A or a vitamin A ester can be stably present in an oil-in-water emulsion cosmetic composition, and furthermore, the composition is easy to use.

[0015] Furthermore, surprisingly, through further intensive research, the present inventors have discovered that by using a specific type of polar oil that does not have a hydroxyl group, vitamin A or a vitamin A ester can be stably present in an oil-in-water emulsion cosmetic composition, and that the composition is easy to use.

[0016] In the present invention, the stability of vitamin A or a vitamin A derivative can be evaluated, for example, by the method described in the Examples below.

[0017] In the present invention, the usability can be evaluated comprehensively mainly based on the fresh feeling and sticky feeling when applying the cosmetic composition.

[0018] <Vitamin A or Vitamin A Derivative> The composition of the present invention contains vitamin A or a derivative of vitamin A. By containing vitamin A or a derivative of vitamin A in the composition of the present invention, it is possible to improve skin firmness and also to impart the effect of improving wrinkles and age spots. Of course, in the present invention, the composition of the present invention may contain both vitamin A and a derivative of vitamin A.

[0019] In the present invention, vitamin A is a general term for retinol, retinal, and retinoic acid, which are classified as fat-soluble vitamins. Therefore, the vitamin A that can be contained in the composition of the present invention may include at least one selected from the group consisting of retinol, retinal, and retinoic acid.

[0020] In the present invention, the vitamin A derivative is not particularly limited and may be, for example, a vitamin A ester. Examples of vitamin A esters include, but are not limited to, vitamin A acetate, vitamin A palmitate, and vitamin A propionate.

[0021] More specifically, in one embodiment of the present invention, the derivative of vitamin A may be retinol acetate, and in another embodiment of the present invention, the derivative of vitamin A may be retinol palmitate.

[0022] In the composition of the present invention, the content of vitamin A or a vitamin A derivative is not particularly limited and may be adjusted appropriately depending on the purpose and use. For example, the content of vitamin A or a vitamin A derivative (when both vitamin A and a vitamin A derivative are contained, the total content thereof) may be 0.05% by mass or more, 0.06% by mass or more, 0.07% by mass or more, 0.08% by mass or more, 0.09% by mass or more, 0.10% by mass or more, 0.15% by mass or more, 0.20% by mass or more, 0.25% by mass or more, 0.30% by mass or more, 0.35% by mass or more, 0.40% by mass or more, 0.45% by mass or more, 0.50% by mass or more, 0.60% by mass or more, 0.70% by mass or more, 0.80% by mass or more, 0.90% by mass or more, 0.10% by mass or more, 0.15% by mass or more, 0.20% by mass or more, 0.25% by mass or more, 0.30% by mass or more, 0.35% by mass or more, 0.40% by mass or more, 0.55% by mass or more, 0.60% by mass or more, 0.70% by mass or more, 0.80% by mass or more, 0.90% by mass or more, 0.10% by mass or more, 0.15% by mass or more, 0.20% by mass or more, 0.25% by mass or more, 0.30% by mass or more, 0.35% by mass or more, 0.40% by mass or more, 0.45% by mass or more, 0.50% by mass or more, 0.60% by mass or more, 0.7 It may be 50% by mass or more, 0.55% by mass or more, 0.60% by mass or more, 0.65% by mass or more, 0.70% by mass or more, 0.75% by mass or more, 0.80% by mass or more, 0.85% by mass or more, 0.90% by mass or more, 0.95% by mass or more, or 1.0% by mass or more, and may be 1.0% by mass or less, 0.9% by mass or less, 0.8% by mass or less, 0.7% by mass or less, 0.6% by mass or less, 0.5% by mass or less, 0.4% by mass or less, 0.3% by mass or less, or 0.2% by mass or less.

[0023] <Polar Oil Having No Hydroxyl Group> The composition of the present invention contains a polar oil having no hydroxyl group. In the present invention, a polar oil having no hydroxyl group is preferred from the viewpoint of not undergoing a transesterification reaction with the vitamin A ester.

[0024] In the present invention, polar oil refers to oils other than silicone oils that have high polarity among oils that can be used in cosmetics, and for example, refers to oils with an IOB value of 0.10 or more, 0.15 or more, 0.20 or more, 0.25 or more, 0.30 or more, 0.35 or more, 0.40 or more, 0.45 or more, 0.50 or more, or 0.55 or more. The IOB value of the polar oil according to the present invention may be 0.60 or less, 0.55 or less, 0.50 or less, 0.45 or less, 0.40 or less, 0.35 or less, 0.30 or less, 0.25 or less, or 0.20 or less. The IOB value is an abbreviation for Inorganic / Organic Balance (inorganic / organic ratio), and is a value that represents the ratio of inorganic value to organic value, and is an index showing the degree of polarity of an organic compound. Specifically, the IOB value is expressed as IOB value = inorganic value / organic value. The "inorganic value" and "organic value" are set according to the type of atom or functional group, such as 20 for one carbon atom in a molecule and 100 for one hydroxyl group. The IOB value of an organic compound can be calculated by integrating the "inorganic values" and "organic values" of all atoms and functional groups in the organic compound (see, for example, "Organic Conceptual Diagram - Fundamentals and Applications" by Yoshio Koda, pp. 11-17, Sankyo Publishing, 1984).

[0025] The polar oil may include, for example, an ester oil, an ultraviolet absorber, or a mixture thereof. Therefore, in the present invention, the polar oil having no hydroxyl groups may include, for example, at least one of an ester oil having no hydroxyl groups, an ultraviolet absorber having no hydroxyl groups, or a mixture thereof.

[0026] More specifically, the polar oil having no hydroxyl group may include, for example, at least one selected from the group consisting of pentaerythrityl tetraethylhexanoate, neopentyl glycol dicaprate, caprylic / capric triglyceride, diethylhexyl succinate, cetyl ethylhexanoate, diisopropyl sebacate, and diisobutyl adipate.

[0027] Among the above, the polar oil having no hydroxyl group preferably contains at least one selected from the group consisting of caprylic / capric triglyceride, diethylhexyl succinate, diisopropyl sebacate, and diisobutyl adipate, because when the polar oil having no hydroxyl group contains at least one selected from the group consisting of caprylic / capric triglyceride, diethylhexyl succinate, and diisobutyl adipate, vitamin A or a derivative of vitamin A can be stably present in the composition of the present invention and the composition is easy to use.

[0028] In the composition of the present invention, the content of the polar oil having no hydroxyl group is not particularly limited, and may be, for example, 7.0 mass% or more, 8.0 mass% or more, 9.0 mass% or more, 10 mass% or more, 11 mass% or more, 12 mass% or more, 13 mass% or more, 14 mass% or more, or 15 mass% or more, relative to the entire composition, or 30 mass% or less, 29 mass% or less, 28 mass% or less, 27 mass% or less, 26 mass% or less, 25 mass% or less, 24 mass% or less, 23 mass% or less, 22 mass% or less, 21 mass% or less, 20 mass% or less, 19 mass% or less, 18 mass% or less, 17 mass% or less, 16 mass% or less, or 15 mass% or less.

[0056] The evaluation criteria are as follows: "A": When the rate of decrease from the initial value is less than 11%; "B": When the rate of decrease from the initial value is 11% or more but less than 14%; "C": When the rate of decrease from the initial value is 14% or more.

[0057] <Evaluation of Usability> Each composition was evaluated for usability based on the feel when applied to the skin of a specialist panel. The evaluation criteria are as follows: "A": Fresh and not sticky "B": Fresh but slightly sticky "C": Not fresh enough and sticky

[0058]

[0059]

[0060] As is clear from the results in Table 1, all of the compositions of Examples 1 to 7 were found to be excellent in stability and ease of use. In particular, the compositions of Examples 3, 4, 6, and 7 were found to have the most excellent results in terms of stability and ease of use.

[0061] In contrast, the compositions of Comparative Examples 1 to 3 were found to be easy to use but had poor stability. The reason for this is analyzed as follows: It is presumed that the compositions of Comparative Examples 1 to 3 did not contain a polar oil without a hydroxyl group, and therefore the vitamin A derivatives contained therein could not be stably maintained.

[0062] Comparative Examples 4 and 5 Oil-in-water emulsion cosmetic compositions of Comparative Examples 4 and 5 were prepared based on the formulations in Table 3. The stability and usability were evaluated in the same manner as above, and the results are shown in Table 3.

[0063]

[0064] As is clear from the results in Table 3, the composition of Comparative Example 4 was found to be inferior in usability. Furthermore, the composition of Comparative Example 5, which had different components from those of Comparative Example 4, was found to have good usability but poor stability.
