Description

Cosmetic composition carrier and cosmetic composition containing the same

This application claims the benefit of priority based on Korean Patent Application No. 10-2017-0155579 dated November 21, 2017, which is incorporated herein by reference in its entirety.

The present invention relates to a cosmetic composition carrier and cosmetics containing the same.

Conventionally, cosmetic composition of liquid form has been mainly filled and packed in a vacuum container, a pump container, a glass container, or the like, but these containers are disadvantageous in portability. In recent years, there has been an increasing demand for a liquid cosmetic composition carrier that is easy to carry, as the necessity of making or modifying the cosmetic composition is improved.

As a container that can easily carry the liquid cosmetic composition, a fact type container can be considered. In order to contain a liquid cosmetic composition in a fact type container, it is necessary to determine whether it is a cosmetic composition carrier that can be used in the container, whether the cosmetic composition can be well filled in the carrier, whether the carrier can homogeneously carry the cosmetic composition for a long period And whether or not an appropriate amount is discharged when the cosmetic composition is to be taken from the carrier into the applicator. In addition, since it is continuously exposed to the outside during use and is contacted by the applicator, a material resistant to contamination by bacteria is preferable.

It has been impossible to provide a cosmetic comprising a carrier capable of exhibiting effects such as moisturizing, covering power and durability of a high viscosity cosmetic composition which is difficult to carry a high viscosity cosmetic composition. In addition, when the cosmetics are applied with the applicator, it is not easy to control the amount of the cosmetics to be discharged. When the cosmetics are stored in an inclined state, there is a problem of stability such as elution of the cosmetics.

Accordingly, the present invention provides a cosmetic composition carrier capable of solving the above problems.

In order to solve the above problems,

An object of the present invention is to provide a cosmetic composition carrier which improves the carrying ability of a cosmetic composition having a high viscosity, has excellent output of a cosmetic composition, and is excellent in storage stability.

It is another object of the present invention to provide a cosmetic comprising the carrier.

In order to achieve the above object,

The present invention relates to a cosmetic composition carrier comprising two or more carrier layers,

The viscosity of the cosmetic composition is 30,000 to 80,000 cps,

The lowermost carrying layer includes pores having an average size of 400 to 1000 mu m,

The topmost loading layer comprises pores of an average size of less than 100 to 400 [mu] m

Wherein the cosmetic composition is carried on a carrier layer other than the uppermost carrier layer.

The present invention also provides cosmetics comprising the cosmetic composition carrier of the present invention.

The cosmetic composition carrier of the present invention can improve the carrying ability of a cosmetic composition having a high viscosity, and has an excellent effect on the output power of the cosmetic composition.

In addition, the cosmetic composition carrier of the present invention does not cause problems such as elution of the cosmetic composition and has an excellent storage stability.

Hereinafter, the present invention will be described in more detail.

The present invention relates to a cosmetic composition carrier comprising two or more carrier layers,

The viscosity of the cosmetic composition is 30,000 to 80,000 cps,

The lowermost carrying layer includes pores having an average size of 400 to 1000 mu m,

The topmost loading layer comprises pores of an average size of less than 100 to 400 [mu] m

The viscosity of the cosmetic composition is 30,000 to 80,000 cps,

Wherein the cosmetic composition is carried on a carrier layer other than the uppermost carrier layer.

The carrier for a cosmetic composition of the present invention contains the above-mentioned carrier layer, so that it is possible to improve the carrying ability of the cosmetic composition having the above viscosity to a high viscosity cosmetic composition.

In addition, when the cosmetic composition supported on the carrier is dispensed using a dispenser, the cosmetic composition can be discharged with less force.

As used herein, the term " carrier " means that it can carry any substance or component exemplified by a composition, and can also be expressed as " carrier " or " mediator ". In addition, " carrier " may be one which is used to discharge the substance deposited thereon to a separate applicator. In this specification, " supporting ability " means the ability to hold and hold any substance or component.

As used herein, the term " excretory ability " or " excretory output " means the amount of cosmetic composition released when a cosmetic composition is taken from a carrier carrying the cosmetic composition by a applicator, Is discharged.

The lowermost support layer includes pores having an average size of 400 to 1000 mu m, and preferably includes pores having an average size of 500 to 800 mu m.

When the average pore size of the lowermost layer is in the range of 400 to 1000 mu m, it is possible to improve the carrying ability of the cosmetic composition having a high viscosity and to easily control absorption or release of the cosmetic composition.

Also, the lowermost carrying layer may have a pore per inch (ppi) per inch, which is 30 to 80 ppi, preferably 40 to 70 ppi.

If the number of pores contained per inch of the lowermost layer is 30 to 80 ppi, it is possible to improve the ability of the cosmetic composition to have a high viscosity.

In the present specification, the number of pores may be a number obtained by accurately measuring the number of pores on a horizontal and vertical 1-inch line using WI-QA-14 (ASTM standard).

The uppermost carrying layer includes pores having an average size of less than 100 to 400 占 퐉, and preferably includes pores having an average size of 200 to 300 占 퐉.

If the pore size of the uppermost carrying layer is less than 100 to 400 탆, the cosmetic composition can be discharged more uniformly.

In addition, the uppermost carrying layer may have a pore per inch (ppi) per inch of 85 to 130 ppi, preferably 90 to 120 ppi.

If the number of pores per inch of the uppermost carrying layer is 70 to 130 ppi, fluidity, absorption and discharge of the cosmetic composition can be facilitated.

The cosmetic composition of the present invention is a high viscosity cosmetic composition having a viscosity of 30,000 to 80,000 cps. In general, a cosmetic composition having a high viscosity has an excellent effect on moisture retention, skin coverage and persistence. However, due to problems such as fluidity and power loss, it has been impossible to carry a cosmetic composition having a high viscosity on a carrier.

Accordingly, the present invention aims to solve the conventional problems by supporting a cosmetic composition having a high viscosity on the carrier of the present invention.

In the present invention, the cosmetic composition having a high viscosity is carried only on the carrier layer except the uppermost carrier layer, and the cosmetic composition is necessarily carried on the lowermost carrier layer. In addition, the pore size of the supported layer is sequentially decreased from the lowermost loading layer to the uppermost loading layer.

By having the above-mentioned pore size as described above, the lowermost-layer-carrying layer is excellent in the supporting ability for the high-viscosity cosmetic composition, so that a higher-viscosity cosmetic composition can be carried on a larger amount, and the elution of the cosmetic composition can be prevented.

In addition, the cosmetic composition carried on the carrier is discharged by the force of the applicator pushing the carrier. The pore size of the carrier layer gradually decreases from the lowermost loading layer to the uppermost loading layer to facilitate the diffusion of the cosmetic composition, The cosmetic composition may be sequentially diffused and discharged from the uppermost layer to the uppermost layer.

In the present invention, the uppermost carrying layer does not carry the cosmetic composition and allows the cosmetic composition to be discharged by diffusion as described above, and the cosmetic composition, which is supported on the carrier layer except for the uppermost carrying layer, It plays a role.

In addition, the pore size of the supported layer decreases sequentially from the lowermost loading layer to the uppermost loading layer, so that the diffusion can be more easily performed, thereby improving the output power of the cosmetic composition.

The height of the carrier of the present invention is 0.5 to 3.5 cm, and the height means the height including all of the lowermost loading layer to the uppermost loading layer.

If the height of the carrier is less than 0.5 cm, excellent supportability to the cosmetic composition can not be obtained, and if the height exceeds 3.5 cm, the cosmetic composition may be difficult to be discharged.

In addition, the height of each of the carrying layers is not particularly limited within the above-mentioned range, but it is preferable that the height of the lowermost carrying layer is the highest.

The height of the carrier of the present invention is higher than the conventional carrier height and higher than the height of the makeup container in which the carrier is filled.

Specifically, the cosmetic composition carrier of the present invention is filled in a space for accommodating a cosmetic container having an open top and an accommodation space therein, and the top surface of the carrier is exposed to the outside of the cosmetic container because the height of the carrier is higher than the height of the cosmetic container .

The carrier may further include a network structure laminated on the upper surface of the carrier. The rim of the network structure is fixed to the entrance of the cosmetic container in a state where the carrier is housed in the container, Whereby the upper surface of the carrier can be in the form of a dome.

In addition, the rim of the reticulated structure may be coupled to the entrance of the cosmetic container in a state fixed to the coupling ring.

That is, the lamination is performed by compressing the top surface of the carrier, which is in contact with the rim of the network structure fixed to the coupling ring, so that the top surface of the carrier is flush with the makeup container, and the carrier not in contact with the rim of the network, And is higher than the height of the cosmetic container and has a dome shape (Fig. 1).

In the present invention, if the carrier has a dome shape as described above, the release of the cosmetic composition is facilitated, and the cosmetic composition can be discharged more uniformly. More specifically, it is possible to provide a cosmetic composition carrier excellent in power output even when the force of pressing the carrier with the applicator is small. In addition, when the carrier is pressed with a weak force, the area of the cosmetic composition applied to the applicator is small and the area of the cosmetic composition applied to the applicator is widened by pressing with a strong force, so that output of the cosmetic composition can be easily controlled .

In addition, the dome-shaped carrier has a curvature (k, kappa) of 0.005 to 0.05, and preferably a curvature of 0.01 to 0.03.

The curvature can be obtained by substituting the radius of curvature (r) obtained from the following equation (1) into the equation (2).

[Equation 1]

r ² = (r - height of the dome) ² + (diameter of the dome / 2) ²

[Amended by Rule 91, 10.12.2018]
The radius of curvature (r), the height of the dome and the diameter of the dome are given in the following Equation (1).

[Amended by Rule 91, 10.12.2018]

&Quot; (2) "

Curvature k = 1 / r

In the present invention, when the carrier has the above-mentioned curvature of 0.005 to 0.05, the cosmetic composition has excellent output power. In the present invention, excellent output power means that the cosmetic composition is discharged at a time from 0.15 to 0.25 g.

In addition, the reticulate structure prevents the dissolution of the cosmetic composition and increases storage stability.

In the present invention, the elution of the cosmetic composition is primarily prevented by using the carrier, and the elution of the cosmetic composition is prevented secondary by laminating the network structure on the carrier, so that even if the cosmetic container filled with the carrier is inclined, The composition may exhibit an effect of not being eluted.

In the present invention, the carrier may have the same or different materials as the materials of the respective carrier layers, and the kind thereof is not specifically limited, but specifically, a sponge sponge, a natural rubber sponge, a synthetic resin sponge, a urethane, a foamed urethane, a latex, an acrylonitrile- Butadiene rubber, butadiene rubber, styrene-butadiene rubber, natural rubber, chloroprene rubber, butyl rubber, isoprene rubber, vulcanized ethylene-propylene rubber, polysulfide rubber, silicone rubber, fluor rubber, urethane rubber, acrylic rubber, ethylene propylene diene monomer Rubber, polyvinyl alcohol, ethylene vinyl acetate, and nitrile rubbers.

In addition, the cosmetic composition to be carried on the carrier may contain at least one member selected from the group consisting of solutions, emulsions, gels, creams and suspensions.

The cosmetic composition may also be in the form of a makeup primer, a makeup base, a liquid or solid foundation, a concealer, a lipstick, a lip gloss, a powder, a lip liner, an eyeliner, a mascara, an eyebrow, an eye shadow, a blusher, , Sunscreen agents, lotions, creams or essences, but are not limited thereto.

The present invention also relates to a cosmetic comprising the cosmetic composition carrier of the present invention.

By carrying the cosmetic composition on the cosmetic composition carrier of the present invention, the above-mentioned cosmetic product can exhibit excellent supporting performance for a high-viscosity cosmetic composition and exhibit excellent fold output.

EXPERIMENTAL EXAMPLE 1 Measurement of carrier force and power output of a cosmetic composition carrier

1-1. Measurement of bearing force

The carrier force of the cosmetic compositions prepared in Examples 1 and 2 and Comparative Example 1 was measured.

After 15 g of the cosmetic composition prepared in Preparation Example 1 was put in a toilet bowl, the lowest layer of each of Examples 1 and 2 and Comparative Example 1 was placed thereon, and then the cosmetic composition was carried through the simple carrying equipment And the amount of the cosmetic composition which was not supported thereafter was measured to measure the supporting force of the cosmetic composition.

That is, the weight of the lowest-most carrying layer of each of the cosmetic container, Examples 1 and 2 and Comparative Example 1 was measured, and then the cosmetic composition of Preparation Example 1 was loaded on each of the lowest- Each of the lowermost layer supported on the cosmetic composition was taken out of the container, and the weight of the container was measured to determine the weight of the cosmetic composition not carried on the lowermost layer.

As a result, 14.8 g of Example 1 and 14.8 g of Example 2 were carried on 15 g of the cosmetic composition, while 12 g of Comparative Example 1 was carried.

From the above results, it was confirmed that the carrier for cosmetic composition of the present invention had pores having an average size of 400 to 1000 탆 in the lowermost layer, and that the carrier for cosmetic composition having high viscosity was excellent.

1-2. Power output measurement

The applicator was placed on the cosmetic composition carrier prepared in Example 1 and the applicator was pressed with a force of 0.1 and 1 kgf with a push / pull gauge (IMADA, model: FS-1K) (Fig. 8 and Fig. 9).

As a result, when pressed with a small force (0.1 kgf), the cosmetic composition was discharged into a small area on the applicator, and when pressed with a large force (1 kgf), it was confirmed that the cosmetic composition was discharged into a large area on the applicator. And the like did not occur.

In addition, the output of cosmetic composition powders of the cosmetic composition carrier prepared in Examples 1 and 2 and Comparative Example 1 was measured.

The applicator was placed on each of the above-mentioned cosmetic composition carriers, and the amount of the cosmetic composition discharged onto the end face of the application port was measured with a push / pull gauge (IMADA, model: FS-1K) The results are shown in Table 2 and FIG. 10 below.
