Description

Cosmetic puff

The present invention relates to a cosmetic puff, and more particularly to a cosmetic puff used for applying a liquid cosmetic composition.

A typical example of the applicator for cosmetics is a puff, which is used to put on cosmetics such as powder or cake powder or twin cake, and apply it to the face area of the human body. BACKGROUND ART [0002] In recent years, as a technique for commercializing cosmetics having fluidity of paste or liquid type into a portable form has been developed, studies on puffs for applying a fluid foundation or the like to skin have been steadily conducted.

The use of puff as a cosmetic applicator is generally used when making a hue. Recently, the term "wet puff" and "dry puff" have been commonly used in the beauty industry. Wet puffs are used to moisturize cosmetic puffs such as lotion and cosmetics, thereby providing a feeling of close contact and an immediate increase in cooling sensation. However, if you use a flat puff that is easy to carry and has a built-in flat puff as a wet puff (cosmetic puff for a cushion fact), the puff becomes damp due to dampness and dripping down to the handle, dirty hands, .

In addition, a wet polyurethane puff which is mainly used in a liquid foundation product generally has a three-layer structure composed of a wet polyurethane / polyurethane sponge / artificial leather (polyurethane material), but the puff having such a structure has a cosmetic The polyurethane sponge, which is the intermediate layer, was deeply infiltrated into the layer of the artificial leather, so that it was wet when used, and the contents were wasted.

Furthermore, when using a floating puff coated with a hooking pile to apply a solid cosmetic composition, it has the same effect as a brush, but has a limitation that it can not be used when applying a liquid cosmetic composition. In other words, it was found that the effect of brush-like effect could not be achieved due to the contents of excessive penetration into the puff.

Accordingly, a problem to be solved by the present invention is to provide a cosmetic puff which provides an excellent cosmetic effect by regulating the absorption amount of a liquid cosmetic composition having moisture.

In addition, the present invention provides a cosmetic puff capable of providing excellent wetting property to a makeup site that properly exhibits a brush effect according to a formed hooked file.

In addition, the present invention provides a cosmetic puff that can prevent excessive absorption of the liquid cosmetic composition into the cosmetic puff.

In order to solve the above-described problems, the present invention provides a cosmetic puff formed of two or more layers including a skin contact layer, wherein the skin contact layer is formed by filling a flocking file, A cosmetic puff for applying a liquid cosmetic composition is provided.

In addition, the present invention provides a cosmetic puff for applying a liquid cosmetic composition, characterized in that it comprises a film layer formed on the skin-contacting layer, which blocks transmission of the cosmetic composition absorbed in the skin-contact layer.

The inventors of the present invention have found that the reason why the brushing effect can not be exhibited when applying the liquid cosmetic composition is because the puffed flocking puff having the flocking file formed thereon is used as a cosmetic puff for applying the liquid cosmetic composition, Which is the cause of excessive penetration. In order to solve the above-mentioned problem, after various attempts have been made, the skin-contacting layer for covering the hooking file is compressed so that the hooking pile is formed at a high density, Brush effect can be demonstrated properly. In addition, it has been confirmed that the effect is further maximized when the puff contains a film layer formed on the skin-contacting layer which blocks transmission of the cosmetic composition absorbed in the skin-contact layer, thereby completing the present invention.

Hereinafter, this will be described in detail.

In the present invention, the "liquid cosmetic composition" includes all of the cosmetic composition having a fluidity or a form capable of transferring oil or moisture through fiber or paper material containing a large amount of water or oil. For example, liquid foundation, cake type foundation, and the like.

In the present invention, the "cosmetic puff" is a cosmetic applicator for impregnating or closely contacting a cosmetic composition and delivering it to a makeup site. The applicator can be manually operated by a user or by external power It can also be activated automatically. The cosmetic puff includes, but is not limited to, a makeup primer, a makeup base, a foundation, a skin cover, a lipstick, a lip gloss, a face powder, a lip liner pencil, an ibra pencil, an eye shadow, a cheek collar, a compact powder, Factor, Powder Fact, Eyebrow, Eye Shadow, Concealer, Blusher, Powder Foundation or Airless. It is also commonly referred to in the industry as a cushioning product. The surface of the cosmetic puff may be planar and may be curved. The shape of the cosmetic puff when viewed from above may be circular, disc, oval, triangular, square, and the like, but is not limited thereto. The shape of the cosmetic puff when viewed from the side may be a square shape, an elliptical shape, or the like, but is not limited thereto. The hardness range is not limited to this, but it may be in the range of 20 to 80 when the sponge is measured with Asker F type hardness meter.

A cosmetic puff according to the present invention includes a skin contact layer on which a fingering pile is formed.

[Skin contact layer formed with hooking file]

In the cosmetic puff according to the present invention, it includes a skin contact layer. The skin-contacting layer is a carrier which carries the liquid cosmetic composition and delivers it to the cosmetic area, and refers to a region in direct contact with the skin.

The skin contact layer according to the present invention is compressed.

More specifically, it is compressed to a compressibility of 10 to 60% with a thickness of 4 to 9 mm. , More preferably 30% to 60%, and most preferably 40% to 60%. The compression ratio means a degree or a degree of compression compared to the thickness before compression. Although the compression ratio can be measured by various methods known in the art, the thickness before compression and the thickness after compression are measured when the force of the press pressure is applied in the vertical direction at a temperature of 250 DEG C for 5 seconds, .

When the skin contact layer according to the present invention is compressed and preferably has a thickness and / or a compressibility in the above range, the brushing effect is exerted by allowing the hooking file to be formed at a high density, thereby exhibiting excellent wetting performance. In the present invention, when the thickness of the skin-contacting layer is less than 4 mm, the thickness of the skin-contacting layer is too small to provide sufficient elasticity. When the thickness is more than 9 mm, there is no problem of cosmetic effect. If the compressibility is less than 10%, the effect of, for example, making the cosmetic texture deteriorates due to the low density of the simulated material. If the compressibility is more than 60%, the compressibility of the sponge is high.

In the skin contact layer according to the present invention, a flocking file is formed.

(See Fig. 2), there is a problem in that the liquid cosmetic composition penetrates to the upper end, so that the hands are contaminated and the usability is poor (refer to Fig. 3). According to the present invention All of these problems have been resolved.

The phishing file has one or more of the following features:

A thickness of 0.2D to 1.5D, or

Length of 0.2mm ~ 1.5mm.

"D (denier)" as the thickness unit of the above-mentioned hooking file is an international unit used for indicating the thickness of the fiber, and a unit length of 0.05 g at a standard length of 450 m is regarded as 1D. That is, the denier is calculated by D = (L / W) x (w / l) (L: standard length, W: unit weight, w: weight of fiber, Therefore, the larger the weight, the larger the fineness, the thinner the finer the fineness, the smaller the fineness.

When the hooking file according to the present invention has a thickness (thickness) and / or a length in the above range, the brush effect is exerted properly and excellent drawing ability is obtained. Specifically, in the present invention, when the thickness of the hooking pile is less than 0.2D, the skin becomes too thin and elastic to cause clumping due to cosmetics and sebum, and it is difficult to exert a brush effect of more than 1.5D. Also, in the present invention, if the length of the hooking file is less than 0.2 mm, the effect of sweeping the content is lost, and the flocking of the flocked files occurs.

The hooking file means a short fiber and the hooking file can be made of a material such as cotton, cotton / acrylic, cotton / acrylic / polyester, cotton / rayon, acrylic, rayon, hemp, silk, nylon, polyester, nylon / But is not limited thereto.

Depending on the length, the thickness, and the material of the hooking file, the feeling of use at the time of skin contact can be changed.

For example, after applying an adhesive to a support (corresponding to a skin contact layer in the case of the present invention), the hooking pile is vertically planted and dried by the electrostatic principle Process can be applied.

The skin contact layer according to the present invention may be at least one selected from porous wet urethane, nitrobutadiene rubber (NBR), styrene butadiene rubber (SBR), natural rubber (NR), and dry polyurethane , Preferably dry polyurethane can be used. More preferably, a polyester material, a polyether material, or a mixture of these materials may be used.

Preferably, the cell size of the material forming the skin contact layer according to the present invention may be an average of 50 μm to 800 μm on the basis of pre-compression. Compressed in the above range, there is no problem in the piling of puffs, Excellent puff can be manufactured.

Preferably, the density of the skin-contact layer according to the present invention may be 0.01 g / cm ³ to 0.1 g / cm ³ on the basis of pre-compression, and a puff having a hardness suitable for use at the time of compression may be manufactured within the above range .

The cosmetic puff according to the present invention comprises a film layer formed on a skin-contacting layer, which blocks transmission of the cosmetic composition absorbed in the skin-contact layer.

[Film layer]

In the cosmetic puff according to the present invention, the film layer refers to an area formed on the skin-contacting layer which blocks transmission of the cosmetic composition absorbed in the skin-contact layer. It may suffice if it is formed on the skin-contacting layer sequentially, and it does not need to be formed in contact with the skin-contacting layer. More specifically, the film layer may be sequentially formed of a skin contact layer, a first intermediate layer, a film layer, and a second intermediate layer. At this time, the film layer can prevent the cosmetic composition from being transferred to the second intermediate layer. Furthermore, it is possible to prevent the second intermediate layer from being transmitted to the outer skin layer. At the same time, when the film layer is formed in this order, the cosmetic composition can be sufficiently puffed to achieve a cosmetic effect.

In the present invention, the thickness of the film layer is not limited thereto, but is preferably 5 to 35 占 퐉, and the thickness deviation may be 10 to 20 占 퐉. Within the above range, the cosmetic composition can be prevented from being absorbed and delivered in an excessive amount.

The film layer may be selected from a material selected from water repellency, oil repellency, or a mixture thereof. More specifically, the film layer may include at least one water repellent material selected from the group consisting of a silicone resin and a fluorine resin resin; Polyurethane, synthetic leather, and rubber (NBR, SBR, etc.); Or a mixture thereof. Preferably, the film layer may be made of a polyurethane material.
