Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic composition which has no stickiness when applied to the skin, has a dry feeling, and does not turn white.

[0002]

2. Description of the Related Art By blending oils into cosmetics,
When the cosmetic is applied to the skin, moisture evaporation of the skin can be suppressed, and flexibility and emollient properties can be imparted. In addition, blending the powder with the cosmetics causes the excess sebum on the skin, components such as sweat to be absorbed into the powder, and cleans the skin.
Due to its absorbing effect, it is widely used for the purpose of enhancing the feeling of use by utilizing the smooth feel.

[0003]

However, if a large amount of oil is blended, adverse effects such as stickiness occur in use, and if a small amount of oil is used, there is no emollient property when applied to the skin, and whiteness of the powder is reduced. Remains. In addition, when only the powder having a small average primary particle diameter is blended, there is no smooth feeling of use which is a characteristic of the powder, and when only the large powder is blended, the skin feels pain with a rough feeling of use. is there. If the amount of oil absorption of the powder is large, the powder becomes white when applied to the skin, and if the amount of oil absorption is small, the oil agent separates and the stability of the system deteriorates. Furthermore, when only silicic anhydride is blended,
A bad effect in terms of use, such as a squeaky feeling, occurred, and when only spherical cellulose and / or spherical cellulose acetate was blended, there was a problem that there was no smooth feeling of use.

[0004]

Means for Solving the Problems In view of such circumstances, the present inventors have conducted intensive studies to obtain cosmetics having a high emollient property and excellent in use, and as a result, a cosmetic containing an oil agent has been obtained. The present inventors have found that the above-mentioned problems can be solved by using silica anhydride and spherical cellulose and / or spherical cellulose acetate in combination, thereby leading to the present invention. That is, the present invention provides: 1. A cosmetic comprising silica anhydride, spherical cellulose and / or spherical acetate, and an oil agent. 2. The cosmetic according to 1, wherein the average primary particle size of the silicic anhydride is 10 μm or more and the oil absorption (JIS pigment test method) is 100 to 200 cc / 100 g. 3. The cosmetic according to 1 or 2, wherein a liquid oil agent is contained in the oil agent in an amount of 3 to 15% by mass based on the total amount of the composition.

[0005]

Embodiments of the present invention will be described below. Silicic anhydride used in the present invention has an average primary particle diameter of 10 μm or more, and an oil absorption of 100 to
It is preferably 200 cc / 100 g.

[0006] The spherical cellulose and spherical cellulose acetate used in the present invention are porous, so that sebum, sweat and the like are absorbed, and cosmetics which are hard to lose their makeup can be prepared. In addition, since the shape is spherical, it is possible to adjust cosmetics with high smoothness on the skin and good touch. As spherical cellulose, for example, cell flow C-2
5 (Chisso) can be used as spherical cellulose acetate, for example, a commercial product known under the trade name of Cellflow TA-25 (Chisso).

The oil agent used in the present invention includes:
For example, stearic acid, isostearic acid, oleic acid,
Higher fatty acids such as myristic acid, higher alcohols such as cetyl alcohol and stearyl alcohol, animal and vegetable oils such as olive oil, jojoba oil, coconut oil, castor oil, macadamia nut oil, lanolin, mink oil, beef tallow, fish oil,

Of these, the liquid oil agent preferably contains 3 to 15% by mass based on the total amount of the composition.

[0008] The cosmetic of the present invention comprises, in addition to the above essential components,
Other ingredients that are usually incorporated into cosmetics, such as fragrances,
Tar pigments, coloring pigments such as iron oxide, pigments such as titanium oxide and zinc oxide, preservatives such as paraben and phenoxyethanol, antioxidants such as dibutylhydroxytoluene, chelating agents such as edetic acid, concentrated glycerin, diglycerin, Polyhydric alcohols such as 1,3-butylene glycol, dipropylene glycol, 1,2-pentanediol, glucose, sorbitol, biopolymers such as hyaluronic acid and collagen, N-stearoyl-L-glutamate, lauryl dimethylaminoacetic acid Surfactants such as betaine, polyoxyethylene fatty acid ester, polyoxyethylene alkyl ether, polyhydric alcohol fatty acid ester, polyglycerin fatty acid ester, and sucrose fatty acid ester, aloe, loofah, peonies, melissa, lemon, assembly, and yokui Plant extracts such as cinnamate and licorice, UV absorbers such as octyl methoxycinnamate, thickeners such as carboxyvinyl polymer, alkyl-modified carboxyvinyl polymer, carboxymethylcellulose, sodium alginate, xanthan gum, citric acid, tartaric acid, lactic acid, etc. Acids, alkalis such as sodium hydroxide, potassium hydroxide, and triethanolamine; vitamins such as retinol, nicotinamide, tocopherol, and ascorbic acid; anti-inflammatory agents such as glycyrrhizic acid derivatives, glycyrrhetinic acid derivatives, allantoin; An activator such as tenyl ethyl ether and a lower alcohol such as ethyl alcohol and isopropyl alcohol can be appropriately compounded within a range that achieves the object of the present invention.

The cosmetic of the present invention may be of any dosage form, and can be used, for example, for skin care cosmetics such as emulsions and creams, makeup cosmetics such as foundations, and aromatic cosmetics.

The present invention will be described in more detail with reference to the following examples, but the scope of the present invention is not limited to these examples. The blending amount in the examples is% by mass.

Emulsion cosmetics were prepared by the usual methods using the compositions shown in Examples 1 to 14 and Comparative Examples 1 to 4, and showed stability, usability,
The whitening after application to the skin was evaluated. The results are shown in Tables 1 to 3. Each evaluation method is as follows.

Stability The emulsified sample was filled in a glass bottle, left at room temperature for 2 weeks, and evaluated by visual observation. ：: There is no separation of the oil agent and it is stable. X: The oily agent was separated and unstable.

Usability (Lackiness and dryness) Ten sensory panelists applied an appropriate amount of the sample to the skin, and evaluated the usability at that time. ：: Eight or more of the ten respondents answered that there was no stickiness and there was a feeling of smoothness. Δ: 5 to 7 persons out of 10 answered that there was no sticky feeling and there was a smooth feeling. ×: 4 or less of 10 respondents answered that they had no sticky feeling and had a smooth feeling.
