Description

[Technical field]

[0001] The present invention relates to a cosmetic preparation, an emulsion cosmetic preparation, a hair cosmetic preparation, and the like. [Background technology]

[0002] Emulsion cosmetics are a commonly used formulation for cosmetics, and for example, water-in-oil emulsion cosmetics are widely used in foundations, primers, sunscreens, etc. because of the light spreadability of the oily outer phase and the long-lasting makeup. On the other hand, oil-in-water emulsion cosmetics are preferred when imparting a moisturizing effect to the skin.

[0003] Also, hair cosmetics for hair, eyelashes, eyebrows, etc. are known. For example, hair cosmetics for hair, such as aerosol type hair cosmetics and hair wax, are known as hair cosmetics for styling hair. However, aerosol type hair cosmetics generally use the fixing power of a hair setting polymer to fix hair, but once the hair style is broken after fixing the hair, there is a problem that the hair cannot be fixed again. Also, hair wax is known to have a high hair setting power, but this hair wax usually has a problem that it is poorly restyling. Also, when used on hair or skin, cosmetics that have a sense of spreading and are easy to use are preferable for users.

[0004] For example, Patent Document 1 proposes a hair cosmetic composition that contains a fluorine-modified silicone and / or a fluorine-modified methylphenylpolysiloxane represented by a specific general formula, and a hair setting agent resin. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Publication No. 10-167933 Summary of the Invention [Problem to be solved by the invention]

[0006] Therefore, a main object of the present invention is to provide a cosmetic composition that is excellent in both setting power and restyling ability, and also in spreadability. [Means for solving the problem]

[0007] As a result of intensive research, the present inventors have found that by using component (A) solid oil, component (B) hydrogenated polyisobutene, component (C) film-forming agent, and component (D) polyethylene glycol and adjusting the ratio of these quantities (content, content by mass, etc.), a cosmetic composition excellent in at least both setting power and hair restyling ability can be provided, and have completed the present invention. Furthermore, the present invention can provide a cosmetic composition excellent in both setting power and hair restyling ability, as well as excellent spreadability.

[0008] The present invention relates to the following components (A) to (D); (A) Solid oil (B) Hydrogenated polyisobutene (C) Film-forming agent (D) Polyethylene glycol: Less than 10% by mass wherein the mass ratio (A) / (D) of the component (A) to the component (D) is 1 to 10, and the mass ratio (B) / (D) of the component (B) to the component (D) is 0.2 to 1.2.

[0009] The present invention also relates to the following components (A) to (D): (A) Solid oil (B) Hydrogenated polyisobutene (C) Film-forming agent (D) Polyethylene glycol: Less than 10% by mass wherein the mass ratio (A) / (D) of the component (A) to the component (D) is 1 to 10, and the mass ratio (B) / (D) of the component (B) to the component (D) is 0.2 to 1.2.

[0010] The cosmetic may be an oil-in-water emulsion type cosmetic. The component (A) solid oil may be a polar wax. The component (B) hydrogenated polyisobutene has a kinetic viscosity at 98.9°C of 50 to 10,000 mm 2 / s may also be used.

The mass ratio (B) / (C) of the component (B) to the component (C) may be 0.2-3. Effect of the Invention

[0011] The present invention can provide a cosmetic composition that is excellent in both setting power and restyling ability, and also in spreadability. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] A preferred embodiment for carrying out the present technology will be described below. The embodiment described below shows an example of a typical embodiment of the present technology, and the scope of the present invention is not narrowly interpreted by this. In this specification, percentages are expressed by mass unless otherwise specified. In addition, the upper limit value (or less) and the lower limit value (or more) of each numerical range (~) can be arbitrarily combined as desired. In addition, the quantitative ratio of the content or the content mass ratio can be appropriately adopted as the quantitative ratio of the usage amount or the usage content ratio.

[0013] 1. Overview of this technology A hair cosmetic product is required to have a setting power capable of fixing the style of hair and maintaining the style that has been created, while at the same time having a hair-styling ability that allows the hair to be readjusted into a desired shape or style using a comb, fingers, etc. after setting. However, there have been many cosmetics that have excellent setting power but poor hair restyling ability, or excellent hair restyling ability but poor setting power, and it is technically difficult to resolve this trade-off relationship in which both effects cannot be achieved at the same time. Therefore, the inventors of the present invention aimed to develop a cosmetic that has excellent setting power and excellent hair restyling ability by eliminating the relationship between tray and off.

[0014] As a result of intensive research, the present inventors have completed a cosmetic composition according to the present technology, which has excellent setting power and excellent restyling properties, by using component (A) solid oil, component (B) hydrogenated polyisobutene, component (C) film-forming agent, and component (D) polyethylene glycol, and adjusting the quantitative ratio (content, mass ratio, etc.) of these components (A) to (D). Based on this adjusted cosmetic composition, the present technology can be used in an emulsified state, and since it is an emulsified composition, it can be used in a wide range of formulations and applications. In addition, since the present technology uses a film-forming agent and solid oil, it is considered that it can also be used for makeup, protection of hair, skin, etc.

[0015] Furthermore, from the viewpoint of user's usability, it is preferable that the cosmetic of the present technology has good spreadability when used. However, conventionally, cosmetic products with excellent setting power tend to have problems such as poor spreadability. The present inventors have also found that, based on the cosmetic of the present technology, it is possible to provide a cosmetic product that has excellent spreadability (good spreadability) in addition to setting power and hair re-styling ability by adjusting the components (A) to (D) and their quantitative ratios (contents, mass ratios, etc.) as shown in the Examples below. The present technology that can achieve the second object can also provide a cosmetic product with better spreadability (good spreadability) when used by the user, and for example, the hair cosmetic of the present technology can be adjusted to the user's desired shape or style (for example, fine bundles) when setting. As a more specific example, when the hair cosmetic of the present technology is applied to the hair and set, it can be adjusted to the desired shape or style, and even when the hair is set again without applying a new cosmetic product after setting, it can be readjusted to the desired shape or style. That is, the second main objective of the present technology is to provide a cosmetic composition that is excellent in both setting power and hair restyling properties, and also has excellent spreadability.

[0016] Furthermore, as shown in the Examples below, the present inventors have found that by adjusting the components (A) to (D) and their quantitative ratios (contents, mass ratios, etc.) based on the cosmetic composition of the present technology, a cosmetic composition can be provided that is excellent in stability over time (particularly emulsion stability over time) in addition to the setting power and hair restyling properties. This has the advantage that the quality of the emulsion state in the present technology can be maintained for a long period of time, and the claimed effects are also likely to be maintained for a long period of time. In other words, the third main objective of the present technology is to provide a cosmetic composition that is excellent in both setting power and hair restyling properties and is also excellent in stability over time.

[0017] Furthermore, as shown in the Examples below, the present inventors have also found that, based on the cosmetic composition according to the present technology, a cosmetic composition excellent in setting power, hair restyling ability, spreadability, and stability over time can be provided by adjusting components (A) to (D) and their quantitative ratios (contents, mass ratios contained, etc.) etc. In other words, the present technology can also have as its fourth main objective the provision of a cosmetic composition excellent in both setting power and hair restyling ability, as well as spreadability and stability over time.

[0018] In this specification, the contents of each configuration and each method (each component, each quantitative ratio, etc.) explained in any of the sections such as "1.", "2.", "3.", "4.", etc. may be omitted as appropriate in the explanation of each section, and the technology or components explained in other sections may be adopted and applied as appropriate to the explanation of each section (each configuration, each method, etc.).

[0088] Hereinafter, the present technology will be described in more detail based on examples, etc. Note that the examples, etc. described below are examples of representative examples, etc. of the present technology, and the scope of the present technology is not to be interpreted narrowly by these.

[0089] Emulsion cosmetics having each composition shown in Table 1 were prepared by a conventional method, and the prepared compositions were used as hair styling products and subjected to various evaluation tests, the results of which are also shown in Table 1. Each composition in Table 1 (total amount of cosmetic) is 100% by mass.

[0090] [Manufacturing method] A: Heat ingredients 9 to 11 and ingredients 14 to 16 to 70 to 80°C and mix uniformly. B: Heat ingredients 1-5, 12, and 13 to 90-100°C and mix uniformly. C: Add B to A and mix until uniformly emulsified. D: C was cooled to room temperature, ingredients 6 to 8 were added, and mixed uniformly to obtain a hair styling product (oil-in-water type).

[0091] (Evaluation method 1: Spreadability, setting power, ease of restyling) For spreadability, setting power and ease of restyling, each sample was evaluated and scored by a panel of 10 experts in cosmetic evaluation, who assessed it according to the following criteria. The average score for each sample was then calculated from the total scores of all panelists, and the results were judged according to the four-level judging criteria below. Regarding spreadability, each sample was applied to hair and evaluated for its ability to spread on the hair. Regarding setting power, each sample was applied to hair, and the setting power after adjusting into the desired shape or style was evaluated. Regarding re-styling properties, each sample was applied to hair, adjusted into a desired shape or style, and then the ease of styling when the hair was adjusted again into the desired shape or style was evaluated. <Absolute evaluation criteria> [Score]: [Evaluation result] 4 points: very good 3 points: Good 2 points: slightly poor 1 point: Defective <4-level evaluation criteria> [Judgment]: [Average score] ◎(Excellent): 3.5 points or more ○ (Good): 2.8 points or more and less than 3.5 points △ (slightly poor): 2.0 points or more and less than 2.8 points × (poor): Less than 2.0 points

[0092] (Evaluation method 2: (Stability over time (50℃ / 1M)) 30 g of each sample was placed in a No. 6 standard glass bottle (Kawaguchi Pharmaceutical Co., Ltd.) and stored in a thermostatic chamber at 50°C for one month (1M), after which the condition was observed. Based on the results, the stability over time was evaluated according to the following three-level evaluation criteria. <Three-level reputation criteria> [Evaluation]: [Judgment] ◎(Excellent): Almost no change in appearance ○ (Good): No separation is observed, but one of the following is observed: deterioration of texture or the occurrence of bumps. × (Fail): Separation is observed, the texture is very poor, and lumps are visible.

[0095] As shown in Table 1, the compositions of Comparative Examples 1 to 3 could not satisfy both the setting power and the hair restyling property. On the other hand, the compositions of Examples 1 to 16 were rated at least "○ (good evaluation)" for both the setting power and the hair restyling property, and were excellent in both the setting power and the hair restyling property. Furthermore, the compositions of Examples 1 to 16 had good spreading and excellent spreadability. Furthermore, the compositions of Examples 1 to 16 were applied to compositions in an emulsified state, and could be used as emulsion cosmetics, and as described later, had excellent emulsion stability over time. Furthermore, the compositions of Examples 1 to 16 could be applied to hair, and therefore could be preferably used as hair cosmetics, and more preferably as hair styling products. The present inventors believe that the compositions of Examples 1 to 16 have both excellent setting power and hair restyling property, and therefore form a soft film after application, and therefore it is possible to provide cosmetics with a wide range of uses and formulations that take advantage of the properties of this soft film. The compositions of Examples 1 to 16 had a pH of 5.0 to 8.0.

[0096] On the other hand, in Comparative Example 1, where the content mass ratio (B) / (D) of component (B) to component (D) in Table 1 exceeds 1.2, spreadability, setting power, and stability over time may be poor. Also, in Comparative Example 2, where the content mass ratio (B) / (D) is less than 0.2, setting power may be poor. Furthermore, in Comparative Example 3, where the content mass ratio (A) / (D) of component (A) to component (D) is less than 1, spreadability, restyling ability, and stability over time may be poor.

[0097] From Table 1, it is considered preferable to use a combination of components (A) solid oil, (B) hydrogenated polyisobutene, (C) film-forming agent, and (D) polyethylene glycol as the composition. In addition, considering Examples 1 to 16 and Comparative Example 3, it is considered preferable that the content of component (D) is less than 10 mass%. It is considered that component (A) is preferably a polar wax rather than a nonpolar wax, and component (C) is preferably a nonionic or cationic film-forming resin, and further, it is considered that vinylpyrrolidone polymer is preferable.

[0098] Considering Examples 1 to 16, it is considered that the content mass ratio of (A) / (D) is preferably 1 to 10, and more preferably 1 to 5. Also, considering Examples 1 to 16, it is considered that the content mass ratio of (A) / (B) is preferably 1 to 15, and more preferably 1 to 10. Also, considering Examples 1 to 16 and Comparative Examples 1 and 2, it is considered that the content mass ratio of (B) / (D) is more preferably 0.2 to 1.2. Also, considering Examples 1 to 16, it is considered that the content mass ratio of (B) / (C) is more preferably 0.2 to 3.0. Also, considering Examples 1 to 16, it is considered that the content ratio of [(A+B) / (C+D)] is more preferably 0.8 to 3.0.

[0099] Furthermore, in each of the compositions of Examples 1 to 16, the spreadability (ease of spreading) was at least "○ (good evaluation)" or higher, and thus, each of the compositions of Examples 1 to 16 was excellent in setting power, ease of restyling, and spreadability. The present inventors believe that, since the spreadability is also excellent in Examples 1 to 16, it is preferable to apply them to cosmetics that are applied to a subject by spreading (for example, gel, wax, solid, mousse, etc.).

[0100] Furthermore, each of the compositions of Examples 1 to 16 had excellent stability over time (50°C / 1M), and in the "evaluation of stability over time", Examples 1 and 3 to 16 were rated "Excellent" (A), and Example 2 was rated "Good" (O). Thus, each of the compositions of Examples 1 to 16 was excellent in setting power, hair restyling ability, spreadability, and stability over time. The present inventors believe that each of the compositions of Examples 1 to 16 is also suitable as an oil-in-water emulsion cosmetic.
