Description

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

Generally, various powders are blended into cosmetics for the purposes of improving skin color, providing protection from ultraviolet rays, and absorbing sweat and sebum. For example, Patent Document 1 describes a solid aqueous gel that combines a hydrophilic gelling agent with starch or a derivative thereof, and Patent Document 2 describes a cosmetic composition that contains a carboxylic acid ester and starch. In these documents, starch is formulated for the purpose of gelling, etc.

On the other hand, Patent Document 3 describes a sunscreen cosmetic that contains ethanol, starch, and an ultraviolet scattering agent or ultraviolet absorbing agent, and this sunscreen cosmetic has a refreshing and smooth feel when applied to the skin.

Special Publication No. 2003-503316 Special Publication No. 2004-529957 Japanese Patent Application Publication No. 11-246379

The sunscreen cosmetic described in Patent Document 3 uses starch to achieve a smooth effect when applied to the skin, but because it contains a high amount of ethanol, it is not possible to incorporate a high amount of an oil-based ultraviolet absorbing agent. In order to incorporate a high amount of an ultraviolet absorbing agent, it is necessary to incorporate a high amount of oil, but since starch is hydrophilic, it is difficult to incorporate starch. After extensive research, the inventors have found that by incorporating specific types of oil in specific ratios, it is possible to obtain a smooth feeling due to starch, even in a formulation with a high ratio of oil.

The present invention was made in consideration of the above circumstances, and aims to provide a cosmetic product that provides a smooth feel even when it contains a high proportion of oil.

The cosmetic preparation of the present invention comprises (A) starch powder;
For oil,
(B) a polar oil; and
(C) a volatile oil component;
The ratio of (C) volatile oil to (B) polar oil is 0.5 or more.

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

The cosmetic composition of the present invention preferably further contains (D) an oil phase thickener.

The cosmetic of the present invention may further contain (E) a non-volatile hydrocarbon oil or a non-volatile silicone oil. In this case, it is preferable that the ratio of (E) the non-volatile hydrocarbon oil or the non-volatile silicone oil to the (B) polar oil is 0.5 or less.

(B) The polar oil may contain an ultraviolet absorber.

The cosmetic of the present invention can be a water-in-oil emulsion cosmetic.

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

The cosmetic preparation of the present invention comprises (A) starch powder;
For oil,
(B) a polar oil; and
(C) a volatile oil component;
Since the ratio of the (C) volatile oil to the (B) polar oil is 0.5 or more, even if the formulation contains a high ratio of oil, a smooth feel can be obtained when used.

The cosmetic of the present invention will be described in detail below.
The cosmetic preparation of the present invention comprises (A) starch powder;
For oil,
(B) a polar oil; and
(C) a volatile oil component;
The ratio of (C) volatile oil to (B) polar oil is 0.5 or more.
Each component will be described in detail below. Each component may be simply referred to as component (A), component (B), etc. In addition, in this specification, PEG stands for polyethylene glycol, PPG stands for polypropylene glycol, PBG stands for polybutylene glycol, EO stands for ethylene oxide, PO stands for propylene oxide, POE stands for polyoxyethylene, POP stands for polyoxypropylene, and VP stands for vinylpyrrolidone.

(A) Starch Powder (A) Starch is not particularly limited as long as it is typically used in cosmetics, pharmaceuticals, and foods, and examples thereof include, but are not limited to, potato starch, corn starch (corn starch), dextrin, and chemically modified products having these skeletons.

Examples of chemically modified substances having a skeleton such as the above-mentioned potato starch, corn starch, dextrin, etc. include hydroxypropyl starch, corn starch sodium octenylsuccinate, corn starch aluminum octenylsuccinate, corn starch triethanolamine octenylsuccinate, starch sodium octenylsuccinate, starch triethanolamine octenylsuccinate, etc., but the functional groups to be chemically modified are not limited to these.
The component (A) may be used alone or in combination of two or more types.

The blending amount of component (A) is preferably 0.1 to 10% by mass, and more preferably 0.5 to 5% by mass, of the total amount of the cosmetic. A blending amount of 0.1% by mass or more can effectively impart a smooth feel to the cosmetic, and a blending amount of 10% by mass or less can ensure stable blending of component (A).

It is preferable that component (A) is dispersed in oil. Starch powder is hydrophilic, but in the cosmetic composition of the present invention, the ratio of volatile oil (C) to polar oil (B) is 0.5 or more, so it is possible to disperse component (A) in oil, and by dispersing it in oil, the user can feel a stronger smooth feeling.

(B) Polar oil The oil contains (B) polar oil. The (B) component is not particularly limited as long as it is normally used in cosmetics, medicines, and foods. The IOB value is not particularly limited, but is preferably 0.05 to 0.80.
The IOB value is an abbreviation for Inorganic/Organic Balance, which is a value that indicates the ratio of inorganic values to organic values, and is an index that indicates the degree of polarity of an organic compound.
IOB value is expressed as inorganic value/organic value. Here, for each of the "inorganic value" and "organic value", the "inorganic value" and "organic value" are set according to various atoms or functional groups, for example, the "organic value" for one carbon atom in a molecule is 20, and the "inorganic value" for one hydroxyl group in the molecule is 100. 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, Fujita, "Chemical Area", Vol. 11, No. 10, pp. 719-725, 1957).

The cosmetic composition of the present invention may be in any formulation, and may be provided in any form, such as an emulsion system, a water-oil two-layer system, or the like.
The cosmetic of the present invention can be used as is or diluted with an oily component to form an oil-based cosmetic, or the cosmetic can be emulsified with an aqueous component by a known method to form a water-in-oil emulsion cosmetic.

When using an aqueous component, any component that can be normally blended in a cosmetic preparation can be used within a range that does not impair the stability of the cosmetic preparation.
Examples of such aqueous components include water, lower alcohols, moisturizing agents, water-soluble thickeners, water-soluble ultraviolet absorbers, sequestering agents, antioxidants, water-soluble drugs, and the like.

The form of the cosmetic of the present invention is not particularly limited, and any form that is conventionally used in cosmetics can be widely applied, such as basic cosmetics such as lotion, milky lotion, cream, facial cleanser, gel, essence (beauty serum), and packs, makeup cosmetics such as lipstick, eye shadow, eye liner, mascara, foundation, and sunscreen, oral cosmetics, fragrance cosmetics, hair cosmetics, and body cosmetics.

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 the following examples, the blend amounts are expressed in mass % unless otherwise specified.
The water-in-oil emulsion cosmetics having the compositions shown in Tables 1 to 3 below were prepared by dispersing the usable powder in an oil phase in a conventional manner.

The feel of the obtained cosmetics when used was evaluated according to the following criteria.
(Smooth feeling)
A panel of five female experts applied the cosmetics to the skin and had them evaluate the smooth feeling.
A: Five panelists rated it as having a smooth feeling. B: Four panelists rated it as having a smooth feeling. C: Three panelists rated it as having a smooth feeling. D: Two or less panelists rated it as having a smooth feeling. The evaluation results are shown in Tables 1 to 3 together with the formulation.

As shown in Table 1, Example 1 containing starch powder had a more pronounced dry feel than Comparative Examples 1 to 3 containing other usable powders. Comparative Examples 4 to 6 shown in Table 2 are those containing the component (C)/(
Since the ratio of the (E) component to the (B) component was less than 0.5, no smooth feeling was felt. Moreover, from Examples 2 and 3, when the ratio of the (C) component to the (B) component was 0.5 or more, a smooth feeling could be obtained. Furthermore, from a comparison of Examples 4, 5, 7, and 8 with Examples 6 and 9 in Table 3, it can be seen that when the ratio of the (E) component to the (B) component was 0.5 or less, a smoother feeling could be obtained.

Next, oil-based cosmetics having the compositions shown in Table 4 below were prepared by conventional methods and evaluated according to the same criteria as above.

As shown in Table 4, it was difficult to obtain a smooth feel in Comparative Examples 7 and 8, in which the ratio of component (C)/component (B) was less than 0.5. Also, a comparison of Examples 10 to 13 shows that when component (E) is included, a smoother feel can be obtained when the ratio of component (E)/component (B) is 0.5 or less.
