Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for selectively removing sebum from skin without removing makeup even when makeup is used, and a method for redressing makeup.

[0002]

2. Description of the Related Art Excessive sebum secretion causes, in particular, forehead, nose,
Many women complain that their chins quickly become greasy, sticky, and their makeup is lost. Conventionally, as a method of removing sebum from the skin, a method of frequently washing the face and a method of pressing oil blotting paper are known. However, facial cleansing has a high sebum removal effect but no selectivity,
At the time of makeup, the foundation and lipstick are also dropped, so the makeup must be re-applied, and there is a problem that it is not easy. In addition, the use of a facial cleanser having a high detergency or frequent face-washing may cause rough skin, firmness, and bulkiness.

On the other hand, oil removing paper can remove sebum easily without removing makeup when using makeup, and is widely used as a general method of restoring makeup. Many people complained that they had become greasy and had to use more than one at a time.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to provide a method for removing sebum from the skin with a high sebum removing effect selectively without removing the make-up even at the time of make-up, and a method for redressing the make-up. .

[0005]

DISCLOSURE OF THE INVENTION The present invention provides a sebum selective remover containing a hydrophilic surfactant and / or ethanol, which is used by spraying on the skin, and a pretreatment agent for redressing makeup. .

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The liquid composition used in the present invention is not particularly limited as long as it is liquid at room temperature and can be sprayed, and may be any of water, an aqueous liquid composition, and an oily liquid composition. Among them, it is preferable to use the aqueous liquid composition, particularly since it has a high refreshing feel after removing sebum.

The aqueous liquid composition preferably contains a hydrophilic surfactant and / or ethanol. Here, as the hydrophilic surfactant, any of a nonionic surfactant, an anionic surfactant, an amphoteric surfactant and a cationic surfactant can be used.

Specifically, examples of the nonionic surfactant include polyoxyethylene castor oil or polyoxyethylene hydrogenated castor oil derivative, polyoxyethylene sorbitan fatty acid ester, polyoxyethylene glycerin fatty acid ester, and polyoxyethylene sorbite. In addition to polyoxyethylene addition-type surfactants such as fatty acid esters, polyoxyethylene alkyl ethers, polyoxyethylene alkyl phenyl ethers, polyoxyethylene polyoxypropylene block polymers, polyglycerin alkyl ethers, polyglycerin fatty acid esters, and sucrose fatty acids Examples include esters and alkyl glucosides.

Examples of the anionic surfactant include N-acyl amino acid salts such as sodium lauroyl sarcosine and sodium lauroyl methylalanine; polyoxyethylene alkyl ether phosphates, polyoxyethylene alkyl sulfates, and alkyl sulfates. Salts, alkyl phosphates, fatty acid salts and the like can be mentioned. Examples of the amphoteric surfactant include alkyl betaine and alkyl amide betaine. Examples of the cationic surfactant include di-long-chain alkyl quaternary ammonium salts, mono-long-chain alkyl quaternary ammonium salts, bis (hydroxyalkyl) quaternary ammonium salts, and quaternary ammonium salts having an amide / ester bond. No.

Of these, 1.2 μL of a 0.5% by weight aqueous solution was dropped onto polyurethane artificial leather (Beaulux, Bioskin No. F-910).
Those having a contact angle of 0 ° or less after 0 seconds are preferable. In the present invention, the contact angle is a value measured using a contact angle meter (manufactured by Kyowa Interface Science Co., Ltd.).

The hydrophilic surfactant can be used singly or in combination of two or more kinds.
1-5% by weight, especially 0.01-3% by weight,
The feeling of the skin after removing the sebum is particularly good and preferable. In addition, it is preferable that ethanol be contained in the liquid composition in an amount of 0.01 to 20% by weight, particularly 0.05 to 10% by weight, from the viewpoint of sebum removing effect and irritation to skin.

On the other hand, when the composition is an oily liquid composition, oily components, for example, hydrocarbon oils such as solid or liquid paraffin, vaseline, squalane, etc .; natural oils and fats such as eucalyptus oil, tallow, olive oil and jojoba oil; Ester oils such as isopropyl myristate and neopentyl glycol dicaprate; higher fatty acids such as stearic acid and linoleic acid; higher alcohols such as cetanol and stearyl alcohol; phospholipids; sphingosine derivatives of natural extraction and synthetic compounds thereof; Cholesterol derivatives such as cholesteryl; silicones such as methylpolysiloxane and methylphenylpolysiloxane; cyclic silicones; modified silicones such as oxazoline-modified silicone; JP-A-8-319263;
An amide derivative or the like described in JP-A-62-228048 can be blended.

Further, in addition to the above-mentioned components, components used in ordinary cosmetics, such as oils, humectants, water-soluble polymers, acids, bases, salts, fragrances, pigments, antioxidants, etc. UV absorbers, whitening agents, blood circulation promoters, vitamins, metal chelators, sebum suppressants, powders, astringents, emollients, cooling agents, anti-inflammatory agents, proteins, amino acids, plant extracts, etc. They can be appropriately selected and blended within a range that does not impair the effects of the invention.

The liquid composition has a contact angle of 80 ° or less, particularly 60 °, when the liquid composition is measured in the same manner as described above.
° or less is preferable because it is easy to adapt to when sprayed on the skin.

In the present invention, such a liquid composition is first sprayed on the skin. The spraying method is not particularly limited, and the liquid composition is a mist having an average particle size of 30 to 200 μm.
As long as the liquid composition can be sprayed onto the skin, for example, the liquid composition can be sprayed by filling a pump type spray container or filling a pressure-resistant container together with a propellant. As these containers and propellants, those usually used for cosmetics and the like can be used. In addition, the injection amount is not particularly limited.
Preferably it is 0.45 mL. By spraying in this manner, the liquid composition can be spread evenly on the skin, and a refreshing feeling can be obtained.

Next, using a water-absorbing or oil-absorbing material, the part sprayed with the liquid composition is pressed and wiped. Examples of the water-absorbing or oil-absorbing material include a polymer gel, a porous material, and a fiber material, and these can be used alone or in combination. Specifically, the polymer gel includes an acrylic acid-based water-absorbing polymer, and the porous material includes a polymer material such as polyamide or a mineral material such as silica.The form is a sponge-like sheet. Shape, puff shape and the like. Fiber materials include pulp, hemp,
Cotton, rayon, acetate, acrylic, polyester, polyethylene, polypropylene, polyurethane,
Examples of the material include polyamide and the like, and examples of the form include compression-molded or lump-shaped fiber materials such as paper such as tissue; woven fabric; non-woven fabric; and cosmetic cotton. By pressing and wiping with these, sebum can be selectively removed together with the sprayed liquid composition. In addition, when using an aqueous liquid composition as a liquid composition, a water-absorbing material is used, and when using an oil-based liquid composition, an oil-absorbing material is used.

When the liquid composition according to the present invention is sprayed on the makeup skin, and then wiped off and then redressed by a usual method, the makeup is well-glued and finished cleanly, and the makeup is good.

[0018]

According to the present invention, sebum can be selectively removed by a simple method, and the makeup does not fall off even at the time of makeup. In addition, it has a high sebum removing effect, removes stickiness and shine, gives a smooth feeling, and gives a refreshing feeling by spraying. Furthermore, when makeup is redressed, the makeup is good and the makeup lasts well.
