Description

Cosmetic puff

The present invention relates to a cosmetic puff, and to a cosmetic puff used to apply a liquid cosmetic composition.

A representative example of a cosmetic applicator may be a puff, which is used to make up while applying cosmetic products such as powder or cake-like powder or twin cake on the face of the human body. In recent years, as the technology of commercializing a cosmetic product having a fluidity of a paste or liquid type into a portable form has been developed, research on a puff for applying a fluid foundation, etc. to the skin has been continuously conducted.

When applying color makeup, puff is mainly used as a cosmetic applicator, and recently, the terms wet puff and dry puff have been commonly used in the beauty industry. A wet puff is a cosmetic puff that is wetted in a liquid cosmetic such as a lotion, and thus has the advantage of providing an increased feeling of adhesion or immediate cooling. However, when using a flat puff that can be carried easily into a pact type as a wet puff (a cosmetic puff for cushion pact), the puff gets wet and gets wet and gets wet to the handle, resulting in poor durability, and the hands are contaminated with the contents during use and the feeling is bad. There was.

In addition, wet polyurethane puffs mainly used for liquid foundation products generally have a three-layer structure consisting of wet polyurethane/polyurethane sponge/artificial leather (polyurethane material). There was a side where the puff was not transferred and was absorbed excessively and penetrated to the intermediate layer of polyurethane sponge, severely to the last artificial leather layer, and was moist when used, and the contents were wasted.

In addition, the flocking puff obtained from the flocking pile has the same effect as a brush when used when applying a solid cosmetic composition, but there is a limitation that it cannot be used when applying a liquid cosmetic composition. That is, it is because a problem in which the effect like a brush cannot be exhibited has been discovered due to the content that excessively penetrates into the puff.

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

In addition, the present invention provides a cosmetic puff that can provide excellent application properties to a cosmetic area that properly exerts a brush effect according to the flocking file.

In addition, the present invention provides a cosmetic puff capable of preventing excessive absorption of the liquid cosmetic composition into the cosmetic puff.

In order to solve the above-described problem, the present invention is a cosmetic puff formed of two or more layers including a skin contact layer, wherein the skin contact layer is a flocking file is planted and compressed, It provides a cosmetic puff for applying a liquid cosmetic composition.

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 contact layer, which blocks the delivery of the cosmetic composition absorbed from the skin contact layer.

As a cosmetic puff for use in applying a liquid cosmetic composition, the present inventors believe that the reason why the flocking puff with a flocking file is not able to properly exert the brush effect when applying the liquid cosmetic composition is a liquid cosmetic composition with a puff. It was confirmed that there is a cause for this excessive penetration. Subsequently, in order to solve the problem causing the above, after various attempts, the skin contact layer for flocking the flocking file is compressed so that the flocking file is planted at a high density, so that the flocking file is planted even when the liquid cosmetic composition is applied. It was confirmed that the brush effect can be properly exerted. In addition, in the case of including a film layer formed on the skin contact layer, which blocks the delivery of the cosmetic composition absorbed from the skin contact layer to the puff, it was confirmed that the effect is further maximized, and the present invention was completed.

Hereinafter, it will be described in detail.

In the present invention, the "liquid cosmetic composition" refers to a cosmetic composition that contains a large amount of water or oil and can transmit oil or moisture through a fiber or paper material, or includes all cosmetic compositions having fluidity. For example, it may include a liquid foundation, a cake type foundation, and the like.

In the present invention, the "cosmetic puff" is a cosmetic applicator for impregnating or in close contact with the cosmetic composition to deliver it to the cosmetic area, and the applicator can be manually operated by a user or by external power (power, etc.) It can also be activated automatically. The cosmetic puff is not limited thereto, but, for example, makeup primer, makeup base, foundation, skin cover, lipstick, lip gloss, face powder, lip liner pencil, eyebrow pencil, eye shadow, cheek color, compact powder, twin cake, It can be applied to pact, powder pact, eyebrow, eye shadow, concealer, blusher, powder foundation or airless. It is also commonly referred to as a cushion product in the industry. The surface of the cosmetic puff may be flat or curved. The shape of the cosmetic puff when viewed from above may be a circular shape, a disk shape, an oval shape, a triangle, and a square shape, but are not limited thereto. The shape of the cosmetic puff when viewed from the side may be a square or an oval, but is not limited thereto. The hardness range is not limited thereto, but may be in the range of 20 to 80 when measuring a sponge with an Asker F type hardness meter.

The cosmetic puff according to the present invention includes a skin contact layer in which a flocking file is planted.

[Skin contact layer where the locking file was planted]

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

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

More specifically, it has a thickness of 4 to 9 mm and is compressed at a compression rate of 10 to 60%. More preferably, it is compressed to 30% to 60%, most preferably 40% to 60%. The compression ratio means the degree or ratio of compression compared to the thickness before compression. The compression rate can be measured according to various methods known in the art, but preferably, the thickness before compression and the thickness after compression are measured when a force of press pressure is applied in the vertical direction at a temperature of 250° C. for 5 seconds, and the difference in thickness before/after It can be obtained through

When the skin contact layer according to the present invention is compressed, and preferably has a thickness and/or compression ratio in the above range, the locking pile is planted at a high density, thereby properly exerting a brush effect and having excellent application properties. In the present invention, when the thickness of the skin contact layer is less than 4mm, the elasticity is insufficient during makeup because the thickness is thin, and when the thickness exceeds 9mm, there is no problem of the makeup effect, but there is a problem that it is inconvenient to carry. If the compressibility is less than 10%, the density of the hair is lowered, resulting in less effect, such as texture formation during makeup, and if the compressibility is more than 60%, the compressibility of the sponge is high, so there is a problem that the elasticity is insufficient when used due to high hardness.

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

In the case of a cosmetic puff in which a conventional flocking file is planted (see Fig. 2), there is a problem that the liquid cosmetic composition penetrates to the upper end, resulting in contamination of the hands and poor usability (see Fig. 3), according to the present invention. All of these problems have been resolved.

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

Thickness from 0.2D to 1.5D, or

Length from 0.2mm to 1.5mm.

"D (denier)", which is the thickness unit of the flocking pile, is an international unit used to indicate the thickness of the fiber, and it is regarded as 1D that the standard length is 450 m and the unit weight is 0.05 g. That is, denier is calculated by D = (L/W) x (w/ℓ) (L: standard length, W: unit weight, w: weight of fiber, ℓ: length of fiber). Therefore, the larger the weight, the thicker and the fineness are, and the lighter the thinner and the fineness is small.

When the flocking pile according to the present invention has a thickness (thickness) and/or a length within the above range, it properly exerts a brush effect and has excellent spreadability. Specifically, in the present invention, if the thickness of the flocking pile is less than 0.2D, it is too thin and less elastic, so that agglomeration occurs due to cosmetics and sebum, and if it exceeds 1.5D, it is difficult to properly exert the brush effect. In addition, in the present invention, if the length of the flocking pile is less than 0.2mm, the effect of sweeping the contents is reduced, and the flocking piles occur, and if it exceeds 1.5mm, the spreadability is deteriorated.

The flocking pile means short fibers, and the flocking pile means, for example, cotton, cotton/acrylic, cotton/acrylic/polyester, cotton/rayon, acrylic, rayon, hemp, silk, nylon, polyester, nylon/polyester. It may include, but is not limited thereto.

Depending on the length, thickness, and material of the locking file, the feeling of use may vary when contacting the skin.

The flocking of the hooking file may be performed according to various methods known in the art, but for example, after applying an adhesive to a support (corresponding to the skin contact layer in the case of the present invention), the hooking file is vertically planted and dried according to the electrostatic principle. It can be done by the process.

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

Preferably, in addition, 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 before compression, and there is no problem with file hair removal when the puff is manufactured by compressing in the above range, and the feeling of use is improved. Excellent puffs can be manufactured.

In addition, preferably, the density of the skin contact layer according to the present invention may be 0.01g/cm ³ to 0.1g/cm ³ based on the pre-compression, and within the above range, it is possible to produce a puff having an appropriate hardness when compressing. .

The cosmetic puff according to the present invention includes a film layer formed on the skin contact layer, which blocks the delivery of the cosmetic composition absorbed from the skin contact layer.

[Film layer]

In the cosmetic puff according to the present invention, the film layer refers to a region formed on the skin contact layer that blocks the delivery of the cosmetic composition absorbed from the skin contact layer. It is sufficient if it is sequentially formed on the skin contact layer, and it is not necessary to form in contact with the skin contact 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 may prevent the cosmetic composition from being transferred to the second intermediate layer. Furthermore, it is possible to prevent transmission to the outer skin layer through the second intermediate layer. At the same time, when the film layer is formed in this order, the cosmetic composition is sufficiently contained in the puff, so that it is easy to achieve the cosmetic effect.

In the present invention, the thickness of the film layer is not limited thereto, but is preferably 5 to 35 μm, and the thickness deviation may be 10 to 20 μm. Within the above range, it is possible to prevent the cosmetic composition from being absorbed and delivered in excess.

The film layer may be made of 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 compound resin; Any one or more oil-repellent materials selected from the group consisting of polyurethane, synthetic leather and rubber (NBR, SBR, etc.); Or it may be made of a mixture thereof, preferably the film layer may use a polyurethane material.

The cosmetic puff according to the present invention is formed of two or more layers. In addition to the above-described skin contact layer and the film layer, a layer to be described later may be additionally included.

Preferably, the cosmetic puff according to the present invention comprises a skin contact layer on which a flocking file is planted; First intermediate layer: a film layer; A second intermediate layer: and an outer skin layer. Considering the locking pile as a separate structure, it has a six-layer structure and can be formed in five layers.

Each of the layers included in the cosmetic puff may be adhered to each other or may be present in a state that is not adhered to each other, and a person skilled in the art may determine whether to adhere or not in consideration of the role and characteristics of each layer in the cosmetic puff. For example, the skin contact layer and the first intermediate layer may exist in an unattached state for absorption and discharge of the cosmetic composition, and in the case of bonding, an adhesive having permeability through which the cosmetic composition can be transmitted may be used. In the case of bonding, it may be connected according to a conventional method known in the art, for example, an adhesive may be applied between one layer and the other layer, and the adhesive may be applied by a spray spray method, but is limited thereto. It doesn't work.

[Cosmetic puff formed of two or more layers]

[Outer skin layer]

The cosmetic puff according to the present invention may include an outer skin layer. The outer layer is the area where the contents can be blocked from being transferred to the hand and the handle can be attached. It may be an area applied to impart an external sense of quality and improve convenience in use.

The material of the outer layer is not particularly limited, and any type of material capable of preventing contamination may be used. For example, materials such as synthetic leather, polyurethane, nylon, cotton, rubber, etc. may be used. Preferably, artificial leather may be used, and more preferably, artificial leather made of a polyurethane material may be used. For example, you can use artificial leather, which the industry calls Jonus.

[Middle floor]

The cosmetic puff according to the present invention may include one or more intermediate layers.

The intermediate layer is a region formed between the skin contact layer and the outer skin layer, has elasticity, has a sense of thickness, and corresponds to a region that selectively absorbs, discharges, and delivers a cosmetic composition.

More specifically, the intermediate layer may be formed of one or more, for example, may be formed of two layers. When formed in two layers, it may be formed as a first intermediate layer, a film layer, and a second intermediate layer with a film layer therebetween.

The intermediate layer is not limited thereto, but may have a thickness of 1 to 10 mm, preferably 2 to 7 mm, in terms of absorbency of the contents and a sense of elasticity during use.

The material of the intermediate layer is not particularly limited, for example, natural rubber (NR), polyethylene, ethylene-vinyl acetate butyl rubber (EVA), latex (latex), styrene-isoprene-styrene (SIS), styrene butadiene. Composed of rubber (SBR), nitrobutadiene rubber (NBR), nitrile butadiene rubber (BR), styrene-ethylene-butylene-styrene (SEBS), polyvinyl alcohol (PVA), non-latex and polyurethane It may be any one or more selected from materials, and preferably polyurethane may be used in consideration of the convenience of the process, cushioning feeling, durability, and the like. Preferably, a hydrophilic polyurethane material may be used. For example, it is possible to use a hydrophilic urethane foam from UltraSORB® from Foamtech. The non-latex material puff may be understood as meaning a puff made of a urethane foam material made dry in the industry, and is a material applied to a puff of a type that expands while meeting water in the industry.

Different materials may be used for the two or more intermediate layers, and the same material may also be used. When different materials are used, it is preferable that the pore size of the intermediate layer in contact with the skin contact layer, more preferably before the film layer, is larger.

In addition, preferably, the first intermediate layer may be a porous structure capable of smoothly moving the contents while having elasticity, and a hydrophilic polyurethane sponge may be used. The hydrophilic polyurethane sponge may be an ether-based polyurethane or an ester-based polyurethane, and in addition, a hydro-carbon-based polyurethane or the like may be used.

In addition, preferably, the second intermediate layer may provide a cushioning feeling of the puff, thereby providing an improved feeling of use. By providing the second intermediate layer, the pressure transmitted from the hand is dispersed so that even application of the cosmetic composition may be possible, and the elasticity and adhesion may be improved.

For example, a film layer may be provided between the first intermediate layer made of polyurethane and the second intermediate layer made of polyurethane. In addition, for example, a film layer may be provided between the first intermediate layer made of polyurethane and the second intermediate layer made of NBR.

The cosmetic puff according to the present invention may be attached by sealing the edge. The sealing may be used without limitation in any method as long as it is a method used by a person skilled in the art to seal the puff, and it may be bonded by applying sealing or hot melt using an adhesive, and ultrasonic or high-frequency sealing may be used.

Even if the puff according to the present invention is used to apply a liquid cosmetic composition, it provides excellent application properties by properly exerting the brush effect by the flocking file, and has superiority without problems in absorption and discharge of the liquid cosmetic composition. Can be used.
