Description

Cosmetic composition applicator comprising a non-permeable sheet

The present invention relates to a cosmetic composition applicator having an antifouling treatment and having antibacterial activity and antifouling ability to adsorb contaminants.

As the portability of the conventional liquid cosmetic composition spreads and the use of the cosmetic composition applicator increases, the form of the applicator to be used also seeks safety and convenience. In the past, there was a built-in applicator of the portable container. There was a problem that the grip grip on the hand falls and the contents are on the hand, and the applicator itself is contaminated and discolored, which is vulnerable to hygiene.

The fact-type container that can easily carry the cosmetic composition is embedded with a thin processed sponge is easy to carry and make-up or to externally apply cosmetics. However, the cosmetic composition applicator embedded in the container as described above is stored in oil and moisture, sebum of the face, and external dust during use and stored for a long time after being embedded in the container, depending on the environment under the hot and humid conditions. There is a problem that can be contaminated. In addition, the continued use of such contaminated applicators may also cause secondary contamination of the cosmetic composition. In addition, the cosmetic composition stuck to the applicator may not be removed even by washing, resulting in messy aesthetic appearance, thereby reducing aesthetics.

Therefore, in order to cleanly and safely use the cosmetic composition applicator, there should be an antimicrobial activity that can prevent the contamination of bacteria, and the selection and processing of materials that can be easily removed even if contaminated is required.

As used herein, "applied apparatus" is a tool for delivering any substance or ingredient to the skin, the broadest meaning including all means of application such as puffs, tips, etc., also referred to as an applicator.

In the present specification, a "sheet" is a member overlaid on one or more sides of an applicator, and is used in the broadest sense including a film, a plate, a film, and the like.

As used herein, the term "contamination prevention layer" of the applicator means a layer for preventing contamination of the cosmetic composition or the external environment from surfaces other than the application surface for delivering the cosmetic composition to the skin in the applicator.

EMBODIMENT OF THE INVENTION Hereinafter, this invention is demonstrated in detail.

One embodiment of the present invention is a coating layer for applying a cosmetic composition to the skin, an elastic layer laminated on top of the coating layer; And an antifouling layer laminated on the elastic layer, wherein the antifouling layer provides a cosmetic composition applicator including a non-transparent sheet. The coating layer may include a coating surface for applying the cosmetic composition to the skin at the lowermost layer of the applicator, and the elastic layer may impart a feeling of use and spreadability of the applicator laminated on the coating layer. The antifouling layer laminated on the elastic layer may prevent contamination from the outside and prevent the cosmetic composition from leaking out by hand.

In one embodiment, the non-permeable sheet included in the antifouling layer of the applicator of the cosmetic composition may be polyurethane. The antifouling layer may be composed of a plurality of layers, for example, and the plurality of layers may be composed of different materials. For example, the antifouling layer may comprise a wet polyurethane layer and a non-permeable sheet laminated thereon, wherein the non-permeable sheet may include at least one of polyurethane, polyethylene, polypropylene, and polymers of polyethylene and polypropylene. Can be.

Polyurethanes may be, for example, dry polyurethanes and wet polyurethanes. Conventional applicators consist mainly of wet polyurethanes, but the wet polyurethanes are hydrophilic, absorbing moisture and do not require additional antimicrobial treatment. There is a problem that is contaminated by. In addition, the cosmetic composition is immediately absorbed when there is a disadvantage that the aesthetic element during the use of the customer falls and does not remove even if washed. Dry polyurethane, on the other hand, has a closed cell structure that contains very little pore or does not contain pores, and therefore does not absorb moisture and oil.

Thus, the antifouling layer of the present invention may include a dry polyurethane sheet as a wet polyurethane layer and a non-permeable sheet laminated thereon as one embodiment. In this way, when the dry polyurethane sheet is laminated on the top of the wet polyurethane layer, the hydrophobicity of the dry polyurethane can prevent the absorption of contaminants and moisture, and the thickness of the antifouling layer is easily provided through the bottom wet polyurethane layer. Can be adjusted. In one embodiment, the dry polyurethane and the wet polyurethane may be composed of layers of the same thickness, or may be composed of layers of different thicknesses. For example, the dry polyurethane sheet may be located on top of the wet polyurethane in the form of a coating layer or film.

Since the non-permeable sheet included in the antifouling layer of the applicator of the cosmetic composition according to an embodiment of the present invention is hydrophobic in which water is not absorbed, the non-permeable sheet is bounced without absorbing moisture or the cosmetic composition, so that a surface other than the coated surface of the applicator is external Contamination from the source can be contained at source. Therefore, even if the cosmetic composition is wiped off with a tissue because it is removed, because the clean state is maintained even during use and easy to use because it only needs to wash the coated surface without problems when washing.

The non-permeable sheet included in the antifouling layer of the applicator of the cosmetic composition according to the embodiment of the present invention, that is, the surface opposite to the application surface of the applicator may be non-porous. More specifically, it may be non-porous containing 5 or less pores per sheet unit area 5 cm × 5 cm. The non-transparent sheet may have a closed cell structure in which each cell does not absorb material. The closed cell structure is substantially the surface of the film-type surface, the material is not absorbed.

In addition, the upper surface of the non-permeable sheet may further include a hydrophobic coating layer including a hydrophobic material to prevent contamination from the outside and to enhance antibacterial activity. In addition, one or more of a silicon-based compound and a fluorine-based compound may be further included, but may be included without limitation if it does not absorb external contaminants or cosmetic composition.

In addition, the thickness of the coating layer may be, for example, 0.001 ~ 0.3 mm. More specifically, the thickness of the coating layer may be, for example, at least 0.001 mm, at least 0.01 mm, at least 0.1 mm, at least 0.5 mm, at least 1 mm, at least 2 mm, at most 3 mm, at most 2 mm, at most 1 mm, at most 0.5 mm. Or 0.1 mm or less. If the thickness is less than 0.001 mm, for example, it may affect the decontamination function of the coating layer, and contaminants may remain without being removed. If it is more than 0.3 mm, the feeling of use and workability may be degraded.

The antifouling layer may have a thickness of, for example, 0.05 to 3.0 mm. More specifically, the thickness of the antifouling layer may be 0.05 mm or more, 0.1 mm or more, 0.5 mm or more, 1 mm or more or 2 mm or more, and may be 3 mm or less, 2 mm or less, 1 mm or less, 0.5 mm or less, or 0.1 mm or less. However, the present invention is not limited thereto so long as it does not decrease the usability of the applicator of the present invention.

The antifouling layer may be, for example, a tensile strength of 3 to 6 kg / cm ³ . More specifically, the tensile strength of the antifouling layer may be 3 kg / cm ³ or more, 3.5 kg / cm ³ or more, 4 kg / cm ³ or more, or 5 kg / cm ^{3 or} more, 6 kg / cm ³ or less, 5.5 kg It may be / cm ³ or less, 5 kg / cm ³ or less, or 4 kg / cm ³ or less, but is not limited thereto so long as the durability of the applicator of the present invention can be maintained. For example, tensile strength of 3 kg / cm ³ If less, the strength is weak and the stability during long-term use and storage may be weakened. For example, in the case of more than 6 kg / cm ³ , the soft texture is inferior and workability may be inferior.

The antifouling layer may have, for example, an elongation of 200 to 700%. For example, if less than 200%, the stability may be lowered, for example, if more than 700%, workability may be lowered.

The non-permeable sheet of the applicator of the cosmetic composition according to an embodiment of the present invention may include one or more irregularities on its upper surface, the irregularities may be formed by embossed surface treatment. The depth of the unevenness may be 10 to 200 μm when the depth is measured at 10 × magnification using a Lext 3D Measuring Laser Microscope OLS4100 device. Concave-convex functions as a protective device as an element that may affect cell formation during processing of the cosmetic composition applicator, and may also provide an aesthetic sense.

In addition, the non-permeable sheet or coating layer of the anti-fouling layer may be laminated by heat-bonding at 100 to 250 ℃ on the layer located at the bottom, respectively. Thermal bonding has high processing efficiency. When the thermal bonding process temperature is less than 100 ℃ adhesive strength is insufficient, if it exceeds 250 ℃ adhesive strength is insufficient or there is a problem that the degree of melting excessively inhibits the completeness.
