Disclosure of Invention

As described in the background art, there is known a polyether urethane foam for impregnating and holding a liquid cosmetic material for transferring the liquid cosmetic material to a cosmetic material application tool such as a puff and applying the same to the skin, but the polyether urethane foam for impregnating and holding a liquid cosmetic material has excellent durability and stability, and further, the polyether urethane foam for transferring the liquid cosmetic material to a cosmetic material application tool and applying the same to the skin is excellent in the feeling of use and the feeling of application when applying the same to the skin. Further, there is no consideration given to the functionality of transferring the liquid cosmetic material to the cosmetic material application tool and supplying the liquid cosmetic material, that is, the change in the amount of impregnation of the liquid cosmetic material, the number of times the liquid cosmetic material can be applied to the cosmetic material application tool, swelling or deterioration due to storage, and further reduction in the amount of residual cosmetic material.

The invention aims to obtain a pad for holding and supplying a liquid cosmetic, which has the following purposes: the amount of impregnation and holding of the liquid cosmetic material is large, and as much liquid cosmetic material as possible in the temporarily impregnated and held liquid cosmetic material can be uniformly and stably transferred to the cosmetic material application tool from the start to the end of use and supplied.

The means for solving the above problems in the present invention are as follows.

1. A pad for holding and supplying a liquid cosmetic, characterized in that a porous sheet is laminated on the surface of a nonwoven fabric.

2. The pad for holding and supplying a liquid cosmetic according to claim 1, wherein the porous sheet is made of an olefin resin.

3. The pad for holding and supplying a liquid cosmetic according to 1 or 2, wherein the fibers constituting the nonwoven fabric are fibers having a PP/PE core-sheath structure.

4. The pad for holding and supplying a liquid cosmetic according to any one of claims 1 to 3, wherein the nonwoven fabric has a density of 8,000 to 45,000 g/m³The nonwoven fabric of (1).

According to the present invention, a larger amount of liquid cosmetic material can be impregnated and held, and the liquid cosmetic material once impregnated and held can be used with a light force from the start of use to the end of use via a cosmetic material application tool, and can be uniformly and stably applied to the skin. In addition, the following advantages are provided: since the liquid cosmetic material holding/supplying pad does not swell and changes its volume little even if the amount of liquid cosmetic material to be impregnated and held is reduced with use from the state of impregnation and holding, the liquid cosmetic material holding/supplying pad can be reliably stored in the container, deterioration can be prevented, and the amount of cosmetic material remaining after use can be reduced.

Detailed Description

(nonwoven fabrics)

The nonwoven fabric used in the present invention may be fibers made of polyester such as PET, or polyolefin such as polyethylene or polypropylene. The nonwoven fabric used in the present invention is preferably such that the fibers themselves constituting the nonwoven fabric do not have water absorption.

In particular, the use of a nonwoven fabric comprising fibers having a PP/PE core-sheath structure makes it possible to maintain the lamination strength of the sheet. The PP/PE core-sheath structure has a polyethylene core and a polypropylene sheath covering the polyethylene core.

The density of the non-woven fabric is preferably 8,000-45，000g/m³More preferably 10,000 to 45,000 g/m³. Further, the thickness of the nonwoven fabric is preferably 3 to 40 mm. When the amount is within this range, the liquid cosmetic can be appropriately impregnated and held and can be appropriately supplied to the cosmetic applicator. The supply of the liquid cosmetic at this time means that the liquid cosmetic is attached to and impregnated into the cosmetic application tool by contacting and pressing the cosmetic application tool on the liquid cosmetic holding/supplying pad of the present invention in which the liquid cosmetic is impregnated and held, and transferring the liquid cosmetic from the liquid cosmetic holding/supplying pad to the cosmetic application tool. The density of the non-woven fabric is less than 8,000 g/m³In the case of using a liquid cosmetic material holding/supplying pad, the thickness of the pad is not sufficient, and the cosmetic material holding property is deteriorated to more than 45,000 g/m³In the case where the liquid cosmetic material holding/supplying pad is too thick, the discharge property of the cosmetic material tends to be deteriorated.

(porous sheet)

As the porous sheet used in the present invention, a known porous sheet having through holes from the front surface to the back surface, which is called a porous web or a porous film, is used, instead of a nonwoven fabric. Among them, a porous sheet having no water absorption property and made of an olefin resin such as a polyester resin, (meth) acrylic resin, polyethylene resin, or polypropylene resin is preferably used. Further, by pressing the cosmetic applicator against the porous sheet to transfer the liquid cosmetic material and use the same, the amount of the liquid cosmetic material transferred to the cosmetic applicator can be prevented from being uneven from the start to the end of use, and the liquid cosmetic material can be applied uniformly and stably to the skin.

When the porous sheet is not used, the amount of the liquid cosmetic transferred to the cosmetic application tool becomes uneven, and therefore, the liquid cosmetic tends to be excessively supplied to the cosmetic application tool particularly immediately after the start of use.

The porosity of the porous sheet is preferably 10 to 100 mesh/inch. When the porosity is too low, it is difficult to supply an appropriate amount of liquid cosmetic from the nonwoven fabric to the cosmetic application tool when taking the liquid cosmetic. If the porosity is too high, the amount of the liquid cosmetic to be supplied at one time becomes too large, and it is difficult to properly perform makeup.

The thickness of the porous sheet is preferably a thickness in a range in which an appropriate amount of the cosmetic material can be supplied to the surface of the cosmetic material application tool. The thickness is 1.0 to 500 μm depending on the porosity.

As a method for laminating such a porous sheet on the surface of the nonwoven fabric, a known method for resin lamination, for example, a method of partial adhesion or welding, can be used.

(liquid cosmetic)

The pad for holding and supplying a liquid cosmetic of the present invention may be impregnated with any of aqueous and oily liquid cosmetics. Only when the liquid cosmetic material holding/supplying pad is impregnated with the liquid cosmetic material and stored in the cosmetic container, a liquid cosmetic material that can be transferred from the pad surface to the cosmetic material application tool and applied to the skin is required.

(method of use)

The pad for holding and supplying a liquid cosmetic of the present invention can be used by a method which is not particularly changed from the conventional pad, for example, by attaching the pad to a cosmetic container or the like and allowing the liquid cosmetic to be absorbed into a sponge or the like.

The surface of the pad for holding and supplying a liquid cosmetic of the present invention on the side where the porous sheet is laminated is pressed with a cosmetic applicator, thereby transferring an appropriate amount of the liquid cosmetic to the cosmetic applicator.

Then, the cosmetic application tool to which the liquid cosmetic is transferred is pressed against the skin with a certain force and applied while being in contact with the skin, thereby performing the intended makeup.

Examples

The liquid cosmetic material holding/supplying pad of the present invention and the pad of the comparative example were attached to a dish-shaped container, and the pad was impregnated with and held by the liquid cosmetic material.

Next, the cosmetic application tool is pressed against the surface of each pad impregnated with and holding the liquid cosmetic, and the liquid cosmetic is transferred to the cosmetic application tool.

And the following actions were repeated to perform the application test of the liquid cosmetic: the application surface of the cosmetic application tool to which the liquid cosmetic is transferred is pressed against the surface of a nonwoven fabric prepared separately.

In tables 1 to 4 below, "nonwoven fabric" is an example of a mat using a non-laminated porous sheet and composed of only the same nonwoven fabric as that of the present invention, "nonwoven fabric + porous sheet" is an example of a mat using the present invention, and "NBR" is an example of a mat using a porous sponge of synthetic rubber NBR.

And as the nonwoven fabric, 20D 100% 390g/m fiber having a PP/PE core-sheath structure was used²。

The dimensions of each pad used in this example were measured when dried. Then, the volume of each pad was calculated from the measured dimensions. The results are shown in table 1.

TABLE 1

Each pad was mounted on a dish (diameter 60 mm. times. height 5mm) and the weight of the pad-mounted dish was measured. Next, the pad attached to each dish-shaped container was impregnated with and held by a liquid cosmetic material (integrated minor water Foundation, manufactured by shiitake corporation), and the weight of the dish-shaped container to which the pad was attached was impregnated with and held by the liquid cosmetic material was measured. And the following operations are performed when the pad is impregnated with and holds the liquid cosmetic material: the liquid cosmetic is slowly impregnated into the pad attached to the dish-shaped container until the liquid cosmetic is in a exuded state by lightly pressing the pad, and the impregnation and holding are performed.

Then, the weight of the pad impregnated with the liquid cosmetic material and the weight of the pad held in the dish-shaped container are calculated from the weight of the pad held in the dish-shaped container and the weight of the pad held in the dish-shaped container after the liquid cosmetic material is impregnated with the liquid cosmetic material, and the weight of the pad held in the dish-shaped container per unit volume of the pad is calculated from the weight of the pad impregnated with the liquid cosmetic material and the volume of the pad during drying. The results are shown in Table 2.

TABLE 2

From the above results, it was found that the amount of impregnation and retention of the liquid cosmetic material in the pad using the nonwoven fabric was larger than that in the NBR pad in which the largest amount of impregnation and retention of the liquid cosmetic material was confirmed among the sponge pads. Further, it is found that the pad in which the porous sheet is laminated on the surface of the nonwoven fabric is slightly pressurized at the time of lamination, and therefore, the amount of the liquid cosmetic impregnated and held per unit volume is increased more than the amount of the liquid cosmetic impregnated and held in the pad made of only the nonwoven fabric.

The pad attached to the dish-shaped container and impregnated and held with the liquid cosmetic was evaluated for continuous application by the cosmetic applicator.

Specifically, the application surface of the cosmetic application tool to which the liquid cosmetic material was transferred was pressed 1 time against each pad impregnated with and holding the liquid cosmetic material, and then the application surface of the cosmetic application tool to which the liquid cosmetic material was transferred was pressed with a light force against the surface of the nonwoven fabric prepared separately. The series of operations was counted as 1 time, and the series of operations was repeated until the liquid cosmetic could not be applied to the surface of the nonwoven fabric (application was completed).

After the application, the weight of the dish-shaped container with the liquid cosmetic left thereon (the weight of the dish-shaped container with the liquid cosmetic applied thereon) was measured. Then, the weight of the pad liquid cosmetic supplied is calculated from the weight of the dish container attached to the pad after the liquid cosmetic is impregnated and held and the weight of the dish container attached to the pad after the liquid cosmetic is applied, and the pad liquid cosmetic supply rate is calculated from the weight of the pad liquid cosmetic supplied and the weight of the pad liquid cosmetic impregnated and held. The results are shown in Table 3.

TABLE 3

Further, the remaining rate of the pad liquid cosmetic was calculated from the weight of the pad liquid cosmetic impregnated and held and the weight of the pad liquid cosmetic supplied. The results are shown in Table 4.

TABLE 4

From the above results, it was found that the supply rate of the liquid cosmetic was much higher in the pad using the nonwoven fabric than in the NBR pad, and the residual rate of the liquid cosmetic was much lower than in the NBR pad.

The results of measuring the number of operations until the end of coating in this experiment are shown in table 5.

TABLE 5

	Number of operations until the end of coating
		Non-woven fabric	271
Nonwoven fabric and porous sheet	331
		NBR	111

From the above results, it was found that the pad using the nonwoven fabric can continuously supply the liquid cosmetic material as compared with the NBR pad. Further, the number of operations from the application end of the mat in which the porous sheet is laminated on the surface of the nonwoven fabric is larger than that of the mat made of only the nonwoven fabric, as compared with the mat made of the nonwoven fabric, and therefore, it is found that the nonwoven fabric can be supplied uniformly and stably with excellent sustainability.

Further, for the purpose of confirming the change in shape of each pad, the size of each pad after the coating was completed was measured, and the linear expansion coefficient of each pad was calculated from the pad size at the time of drying and the pad size after the coating was completed.

TABLE 6

The linear expansion coefficient is calculated by the size of the length and the width. The thickness is not of concern.

From the above results, it is understood that the linear expansion coefficient of the mat using the nonwoven fabric is far lower than that of the NBR mat. Further, it is found that the porous sheet of the pad in which the porous sheet is laminated on the surface of the nonwoven fabric can restrict the expansion of the nonwoven fabric and has a lower linear expansion coefficient than the pad made of only the nonwoven fabric. Here, the low linear expansion coefficient means that the pad itself is less deformed, and therefore, it is understood that the pad is excellent in preventing deformation and deterioration during storage.

From the results of the above-described liquid cosmetic application test, it is understood that the cosmetic composition has the following characteristics: the liquid cosmetic material holding/supplying pad of the present invention has a higher impregnation/holding capacity than a sponge pad and a higher supplying capacity of the liquid cosmetic material because the nonwoven fabric is used, and further, the liquid cosmetic material can be supplied uniformly and stably compared to a pad made of only a nonwoven fabric because the porous sheet is laminated on the surface of the nonwoven fabric, and the pad itself is less deformed and deteriorated.

Therefore, the pad for holding and supplying a liquid cosmetic of the present invention is useful in the following respects: as a base material to be attached to a cosmetic container or the like and impregnated with and hold a liquid cosmetic, the cosmetic can be stably supplied in a larger amount, and can be securely held in the cosmetic container without swelling or deterioration even when stored.
