Description

Technical Field

[0001] The present invention relates to cosmetics, and more particularly to cosmetics containing starch powder.

Background Art

[0002] Generally, in cosmetics, various powders are blended for purposes such as skin color improvement, UV protection, and adsorption of sweat and sebum. For example, Patent Document 1 describes a solid aqueous gel prepared by combining a hydrophilic gelling agent and starch or its derivative, and Patent Document 2 describes a cosmetic composition containing a carboxylic acid ester and starch. In these documents, starch is formulated for purposes such as gelling.

[0003] On the other hand, Patent Document 3 describes a sunscreen cosmetic containing ethanol, starch, and an ultraviolet scattering agent or ultraviolet absorber, and this sunscreen cosmetic has a feeling of use such as a refreshing feeling and a smooth feeling when applied to the skin.

Summary of the Invention

Problems to be Solved by the Invention

[0005] The sunscreen cosmetic described in Patent Document 3 can achieve a smooth effect when applied to the skin due to starch, but since it contains a high proportion of ethanol, it is not possible to formulate a high proportion of an oily ultraviolet absorber. If one attempts to formulate a high proportion of an ultraviolet absorber, it is inevitably necessary to formulate a high proportion of oil, but since starch is hydrophilic, it is difficult to formulate starch. As a result of the intensive studies conducted by the present inventor, it has been found that by formulating the types of oil in a specific ratio, it is possible to obtain a smooth feeling due to starch even in a formulation with a high proportion of oil.

[0006] The present invention has been made in view of the above circumstances, and an object thereof is to provide a cosmetic that can achieve a smooth feeling of use even in a formulation with a high proportion of oil.

Means for Solving the Problems

It is preferable that (A) the starch powder is dispersed in the oil component.

[0008] It is preferable that the cosmetic of the present invention further contains (D) an oil phase thickener.

[0009] It is preferable that the cosmetic of the present invention further contains (E) a non-volatile hydrocarbon oil or a non-volatile silicone oil, and in this case, the ratio of (E) the non-volatile hydrocarbon oil or the non-volatile silicone oil to (B) the polar oil component is preferably 0.5 or less.

[0010] (B) The polar oil component can contain an ultraviolet absorber.

[0011]

[0012] ​The cosmetic of the present invention can be an oil-in-water type emulsion cosmetic.

[0013] The cosmetic of the present invention can be an oil-based cosmetic.

Effects of the Invention

[0014] The cosmetic of the present invention contains (A) starch powder and, in the oil component, (B) a polar oil component, and (C) a volatile oil component and, since the ratio of the (C) volatile oil component to the (B) polar oil component is 0.5 or more, even in a formulation with a high oil content ratio, a smooth feeling of use can be obtained.

Modes for Carrying Out the Invention

[0015] Hereinafter, the cosmetic of the present invention will be described in detail. The cosmetic of the present invention contains (A) starch powder and, in the oil component, (B) a polar oil component, and (C) a volatile oil component and, the ratio of the (C) volatile oil component to the (B) polar oil component is 0.5 or more. Hereinafter, each component will be described in detail. In addition, each component may be simply referred to as the (A) component, the (B) component, etc. Further, in this specification, PEG is an abbreviation for polyethylene glycol, PPG is an abbreviation for polypropylene glycol, PBG is an abbreviation for polybutylene glycol, EO is an abbreviation for ethylene oxide, PO is an abbreviation for propylene oxide, POE is an abbreviation for polyoxyethylene, POP is an abbreviation for polyoxypropylene, and VP is an abbreviation for vinyl pyrrolidone.

[0016] (A) Starch powder (A) The starch is not particularly limited as long as it is usually used in cosmetics, pharmaceuticals, and foods. For example, potato starch, corn starch (corn starch), dextrin, or chemically modified products having these skeletons can be mentioned, but it is not limited to these.

[0017] Examples of the chemically modified products having a skeleton such as the above-mentioned potato starch, corn starch, dextrin, etc. include hydroxypropyl starch, sodium octenyl succinate corn starch, aluminum octenyl succinate corn starch, triethanolamine octenyl succinate corn starch, sodium octenyl succinate starch, triethanolamine octenyl succinate starch, etc. However, the functional groups for chemical modification are not limited thereto. The component (A) may be used alone or in combination of two or more.

[0018] The blending amount of the component (A) is preferably 0.1 to 10% by mass, more preferably 0.5 to 5% by mass in the total amount of the cosmetic. When the blending amount is 0.1% by mass or more, a smooth feeling can be effectively imparted to the cosmetic, and when the blending amount is 10% by mass or less, the component (A) can be stably blended.

[0019] The component (A) is preferably dispersed in the oil component. Although starch powder is hydrophilic, in the cosmetic of the present invention, since the ratio of the (C) volatile oil component to the (B) polar oil component is 0.5 or more, it is possible to disperse the component (A) in the oil component, and by being dispersed in the oil component, a smoother feeling can be felt more strongly.

[0020] (B) Polar oil component The oil component contains the (B) polar oil component. The component (B) is not particularly limited as long as it is usually used in cosmetics, pharmaceuticals, and foods. The IOB value is not particularly limited, but is preferably 0.05 to 0.80. The IOB value is an abbreviation of Inorganic / Organic Balance, which represents the ratio of the inorganic value to the organic value and is an index indicating the degree of polarity of an organic compound. Specifically, the IOB value is IOB value = inorganic value / organic value It is represented as follows. Here, for each of the "inorganic value" and the "organic value", for example, the "organic value" is 20 for one carbon atom in the molecule, and the "inorganic value" is 100 for one hydroxyl group. The "inorganic value" and the "organic value" corresponding to various atoms or functional groups are set. By integrating the "inorganic value" and the "organic value" of all atoms and functional groups in the organic compound, the IOB value of the organic compound can be calculated (for example, see Fujita, "Chemical Field", Vol. 11, No. 10, pp. 719 - 725, 1957).

Example

[0071] The present invention will be described in more detail below with reference to examples, but the present invention is not limited to these examples. In addition, the blending amounts in the following examples and the like indicate mass% unless otherwise specified. Regarding the water-in-oil type emulsified cosmetics having the compositions listed in Tables 1 to 3 below, the usability powder was dispersed in the oil phase and prepared by a conventional method.

[0072] The feel in use of the obtained cosmetics was evaluated according to the following criteria. (Smooth feeling) Five female expert panels were asked to apply the cosmetics to their skin for evaluation of the smooth feeling. A: All 5 panels evaluated that there was a smooth feeling. B: 4 panels evaluated that there was a smooth feeling. C: 3 panels evaluated that there was a smooth feeling. D: 2 or fewer panels evaluated that there was a smooth feeling. The evaluation results are shown in Tables 1 to 3 together with the formulations.

[0075]

Table 3

[0076] As shown in Table 1, Example 1 containing starch powder was significantly smoother compared to Comparative Examples 1 to 3 containing other usability powders. Comparative Examples 4 to 6 shown in Table 2 had no smooth feeling because the (C) component / (B) component was less than 0.5. Also, from Examples 2 and 3, when the (C) component / (B) component was 0.5 or more, a smooth feeling could be obtained. Furthermore, from the comparison between Examples 4, 5, 7, and 8 and Examples 6 and 9 in Table 3, it can be seen that when the (E) component / (B) component is 0.5 or less, a smoother feeling can be obtained.

[0077] Next, an oil-based cosmetic having the composition listed in Table 4 below was prepared by a conventional method and evaluated according to the same criteria as above.

[0078]

Table 4

[0079] As shown in Table 4, Comparative Examples 7 and 8 in which the (C) component / (B) component was less than 0.5 were less likely to obtain a smooth feeling. Also, from the comparison of Examples 10 to 13, it can be seen that when the (E) component is included, when the (E) component / (B) component is 0.5 or less, a smoother feeling can be obtained.
