Description

Cosmetic carrier and cosmetic application set comprising the same

The present disclosure relates to a cosmetic carrier and a cosmetic application set comprising the cosmetic carrier and a cosmetic applicator.

Cosmetics are products used on the human body to clean and beautify the human body to add attractiveness, to brighten the appearance, or to maintain or promote the health of the skin and hair, and have a slight effect on the human body.

In general, cosmetics can be manufactured by mixing cosmetic compositions of different formulations using emulsifiers such as surfactants, and water-in-oil (W/O) and water-in-water (O/W) types depending on the bonding structure of oil and water phase raw materials. It can be classified by the cosmetic composition of

The water-in-oil cosmetic composition is a combination of an oil phase raw material on the outside of the aqueous phase raw material. The water-in-oil cosmetic composition has a lot of oily feeling, so skin absorption is slow and the feeling of use is heavy, but it has the advantage of higher durability than the oil-in-water cosmetic composition. manufacture

The water-in-oil cosmetic composition has disadvantages in that it feels heavy and sticky, and in order to compensate for this, it is generally manufactured by lowering the viscosity of the cosmetic composition. In such a low-viscosity water-in-oil type product, when stored for a long period in a container during distribution, the aqueous phase raw material and the external oil phase raw material may be separated from each other. there is rom

In addition, when the viscosity of the water-in-oil cosmetic composition is high, for example, in order to use a cosmetic composition in a cream formulation, a separate tool for removing a high-viscosity cream such as a spatula is used, or it is inconvenient to take it out by hand. there was.

In order to solve this problem, cosmetics, ie, fact products, have been developed in which the cosmetic composition is supported on a carrier such as a mesh structure or a sponge to discharge the cosmetic composition using a cosmetic applicator.

However, when a cosmetic composition with a low shear stress has a high viscosity, when a shear rate is applied in a certain range, the viscosity decreases rapidly. As a result, the cosmetic composition is easily diluted and discharged in excess, and there is a problem in that it is difficult to discharge an appropriate amount. That is, since the discharge structure is in an unstable state, the mesh structure is not suitable for application to a cosmetic composition having a low shear stress.

In addition, when a conventional carrier such as a sponge is applied, the cosmetic composition does not absorb moisture well by the sponge due to the low shear stress of the cosmetic composition (the conventional sponge carriers are all optimized for the low-viscosity cosmetic composition), the shear stress is The compatibility between the low cosmetic composition and the conventional sponge is greatly inferior. In other words, when pressure is applied to the sponge for discharging because it does not absorb moisture well, the contents are not discharged well, and a phenomenon occurs. In addition, a large force is applied to the sponge for discharge, which affects the shear stress of the cosmetic composition, causing the stability and physical properties of the cosmetic composition to change, and as a result, the intended use and stability cannot be expected.

Accordingly, the present inventors, after repeating countless experiments and failures, have developed a cosmetic carrier that can support a cosmetic composition with a low shear stress and is optimized for brush use at the same time, and a cosmetic application set including the same.

One embodiment is to provide a cosmetic carrier in which moisture absorption of a cosmetic composition with low shear stress is easy and the cosmetic composition is properly discharged even when a brush in a horizontal direction is used.

Another embodiment is to provide a cosmetic application set comprising the cosmetic carrier and the cosmetic applicator.

According to one embodiment, after arranging five stacked structures in which four cosmetic carriers having a diameter of 48 mm and a height of 10 mm are stacked in a cross shape, located in the center of the five stacked structures arranged in a cross shape A cosmetic carrier having a hardness of 60 or less is provided when measuring with an ASKER hardness meter F type on the upper surface of the laminated structure.

The cosmetic carrier may satisfy Equation 1 below.

[Equation 1]

10 < (T2/T1) x 100 < 94

In Equation 1 above,

T1 is the thickness when no force is applied to one cosmetic carrier on which the cosmetic composition is supported,

T2 is the thickness when a force is applied to one cosmetic carrier on which the cosmetic composition is supported.

The cosmetic carrier may be an ether-based polyurethane.

The cosmetic carrier may have a form of foam with a porous structure.

The average particle diameter of the pores in the cosmetic carrier having the foam form may be 250 μm to 500 μm, and the average thickness of the pore walls may be 40 μm to 70 μm.

The cosmetic carrier having the foam form may have a density of 15 kg/m ³ to 25 kg/m ³ .

Another embodiment provides a cosmetic application set comprising the cosmetic carrier and the cosmetic applicator.

The cosmetic composition supported on the cosmetic carrier may be a water-in-oil cosmetic composition.

The initial viscosity of the cosmetic composition supported on the cosmetic carrier may be 3000 cps to 40000 cps.

When a shear rate in the range of 10 ¹ (1/S) to 10 ³ (1/S) is applied to the water-in-oil cosmetic composition, the emulsified particles in the water-in-oil cosmetic composition may be broken.

The cosmetic applicator may be a brush.

The cosmetic application set may further include a mesh network.

The mesh network may have a woven structure of weight 200 g/cm ² or less.

The mesh network may have a thickness of 150D (denier) or less.

The mesh network may not be fixed in the cosmetic application set.

The cosmetic application set may further include a cosmetic carrier accommodating container for accommodating the cosmetic carrier.

The cosmetic carrier according to one embodiment is easy to absorb moisture in the cosmetic composition having a low shear stress, and in addition, if a brush is used together with a mesh network of a woven structure, the cosmetic carrier moves up and down when using the brush in the horizontal direction, The cosmetic composition is discharged in an appropriate amount. Specifically, by applying a lightweight mesh network to the cosmetic carrier on which the cosmetic composition having a low shear stress having a soft characteristic is supported, a sense of unity with the cosmetic composition is formed, that is, there is no air layer between the mesh network and the cosmetic carrier and the cosmetic composition. Therefore, there is no obstacle to the discharge of the cosmetic composition, the cosmetic composition can be discharged in an appropriate amount. In addition, it has an excellent effect on improving the user's feeling of use and aesthetics.

Hereinafter, embodiments of the present invention will be described in detail so that those of ordinary skill in the art to which the present invention pertains can easily implement them. However, the present invention may be embodied in many different forms and is not limited to the embodiments described herein.

In the present specification, when a part such as a layer, film, region, plate, etc. is "on" another part, it includes not only the case where the other part is "directly on" but also the case where there is another part in the middle. Conversely, when we say that a part is "just above" another part, we mean that there is no other part in the middle.

Hereinafter, a cosmetic carrier according to an embodiment and a cosmetic application set including the same will be described.

The conventional liquid pact formulation was a system for absorbing and discharging the cosmetic composition to a sponge (carrier). In order to absorb and discharge the cosmetic composition to the sponge, it is advantageous for the cosmetic composition to form a low viscosity of a certain viscosity or less. This is because, when the viscosity of the cosmetic composition is low, it is possible to express thin, light, moist, and shiny skin with makeup. However, in this case, there is a disadvantage that the coverage is not high. That is, users who use the conventional liquid pact formulation always have a need for coverage, and have been steadily making efforts to satisfy the coverage while using a low-viscosity cosmetic composition. In addition, coverage is a basic attribute in base makeup, and thin and light cover makeup is an essential need of makeup.

In order to solve this problem, the present inventors prepared a water-in-oil cosmetic composition with a low shear stress, and the water-in-oil cosmetic composition with a low shear stress has a high initial viscosity compared to general emulsified contents (water-in-oil cosmetic composition), but a shear within a certain range It was confirmed that the viscosity was rapidly lowered at the shear rate, the instantaneous shear stress was reduced, and it was confirmed that the makeup was light and softly applied. In order to carry a water-in-oil cosmetic composition with such a low shear stress, a suitable content discharge structure must be applied, and the present inventors have undergone countless discussions, trial and error and experiments, It led to the development of a cosmetic carrier that is easy to discharge and a cosmetic application set including the same.

As described above, in the case of a conventional sponge, it is optimized for a low-viscosity cosmetic composition with a high shear stress, so the absorption and discharge of the cosmetic composition with a low shear stress is not good. Again, the current situation is only to confirm that the emission structure is in an unstable state.

However, the cosmetic carrier according to an embodiment has a hardness of 60 or less based on the ASKER hardness group F-type (Type), and specifically has a diameter of 40 mm to 55 mm and a height of 5 mm to 15 mm, specifically a diameter of 48 mm. And after arranging five stacked structures in which four cosmetic carriers having a height of 10 mm are vertically stacked in a cross shape, an asker is placed on the upper surface of the stacked structure located in the center among the five stacked structures arranged in a cross shape. Since the hardness is 60 or less, such as 50 or less, such as 40 or less, when measuring with the hardness group F-type placed on it, moisture absorption and discharge of the cosmetic composition having a low shear stress can be easily performed.

For example, the cosmetic carrier according to an embodiment may satisfy Equation 1 below. At this time, the force applied to one cosmetic carrier may be 20 g Force to 500 g Force.

[Equation 1]

10 < (T2/T1) x 100 < 94

In Equation 1 above,

T1 is the thickness when no force is applied to one cosmetic carrier on which the cosmetic composition is supported,

T2 is the thickness when a force is applied to one cosmetic carrier on which the cosmetic composition is supported.

For example, the cosmetic carrier according to an embodiment may satisfy Equation 2 below. At this time, the force applied to one cosmetic carrier may be 30g Force to 500g Force.

[Equation 2]

15 < (T2/T1) x 100 < 93

For example, the cosmetic carrier according to an embodiment may satisfy Equation 3 below. At this time, the force applied to one cosmetic carrier may be 50g Force to 500g Force.

[Equation 3]

20 < (T2/T1) x 100 < 92

For example, the cosmetic carrier according to an embodiment may satisfy Equation 4 below. At this time, the force applied to one cosmetic carrier may be 100g Force to 500g Force.

[Equation 4]

25 < (T2/T1) x 100 < 80

In Equations 2 to 4,

T1 is the thickness when no force is applied to one cosmetic carrier on which the cosmetic composition is supported,

T2 is the thickness when a force is applied to one cosmetic carrier on which the cosmetic composition is supported.

For example, the cosmetic carrier according to one embodiment is 60 or less, such as 50 or less, such as 40 or less, such as 1 or more and 60 or less, such as 1 or more and 50 or less, such as 1 or more and 40 or less, based on the ASKER hardness level F type. It may have the following hardness. When the hardness satisfies the above range, the cosmetic composition having a low shear stress is discharged on the brush in an appropriate amount. For example, if the hardness is less than 1, a cosmetic composition with low shear stress may be excessively discharged from the carrier. There may be a problem that the cosmetic composition is not discharged.

For example, the cosmetic carrier may be an ether-based polyurethane. Since the ether-based polyurethane has excellent wear resistance and durability, damage to the carrier may not occur even if a load is applied to the carrier to take the cosmetic composition with a brush.

In the case of sponges (carriers) specialized for conventional low-viscosity cosmetic compositions, there were cases where the material was ether-based polyurethane. Nevertheless, the reason that the conventional sponge did not absorb and discharge the cosmetic composition with low shear stress well is because the hardness and Equation 1 are not satisfied. Furthermore, even if both the cosmetic carrier according to an embodiment and the conventional sponge have a foamed form having a porous structure, the cosmetic carrier according to an embodiment is 250 μm to 500 μm, such as 250 μm to 450 μm, such as 250 μm to 400 μm, for example, may have pores having an average particle diameter of 250 μm to 350 μm, and also 40 μm to 70 μm, such as 50 μm to 70 μm, such as 51 μm to 70 μm, such as 52 μm to 70 μm, such as 53 μm to 70 μm, such as 54 μm to 70 μm, such as 55 μm to 70 μm, such as 56 μm to 70 μm, such as 57 μm to 70 μm, such as 58 μm to 70 μm, such as 59 μm to 70 μm, such as 60 μm to 70 μm, such as 61 μm to 70 μm, such as 62 μm to 70 μm, such as 63 μm to 70 μm, such as 64 μm to 70 μm, such as 65 μm to 70 μm, such as 60 μm to 69 μm, such as 60 μm to It may have a pore wall having an average thickness of 68 μm, for example 60 μm to 67 μm, plus 15 kg/m ³ to 25 kg/m ³ , such as 16 kg/m ³ to 24 kg/m ³ , such as 17 kg/m ³ to 23 kg/m ³ , for example, 17.3 kg/m ³ to 23.3 kg/m ³ , while having a density of 23.3 kg/m 3 All sponges had no choice but to facilitate moisture absorption and discharge of cosmetic compositions with low shear stress.

That is, the cosmetic carrier according to one embodiment is made of an ether-based polyurethane material, and since the density, the average particle diameter of the pores, and the average thickness of the pore walls are controlled within a specific range, it is very soft and has a foamed form unlike conventional sponges. By continuously maintaining it, it can be easy to absorb and discharge the cosmetic composition with low shear stress.

Another embodiment provides a cosmetic application set comprising the cosmetic carrier and the cosmetic applicator.

For example, the cosmetic composition supported on the cosmetic carrier may be a water-in-oil cosmetic composition.

For example, the water-in-oil cosmetic composition supported on the cosmetic carrier may be a water-in-oil cosmetic composition having a low shear stress.

In general, makeup compositions are divided into oil-in-water (O/W) compositions and water-in-Oil (W/O) compositions, and oil-in-water compositions have a lighter feel compared to water-in-oil compositions. has advantages, but has disadvantages such as poor water resistance and makeup durability due to the form of traumatic water, and color discoloration due to sebum. On the other hand, the water-in-oil type composition has excellent water resistance to sweat and oil resistance due to sebum because the trauma is oily, but has a disadvantage in that it is difficult to realize initial moisture application compared to the oil-in-water composition.

For the implementation of the initial moisture application property pointed out as the above problem, when the cosmetic composition is prepared by increasing the content ratio of the inner phase (water phase) or adjusting the ratio of the surfactant, there is a problem in that it is difficult to maintain the stability of the formulation. .

However, when a cosmetic composition with a low shear stress is prepared as a water-in-oil composition, it is possible to realize initial moisture application properties while maintaining the advantages of a general water-in-oil composition.

For example, the initial viscosity of the cosmetic composition supported on the cosmetic carrier may be 3000 cps to 40000 cps, for example, 20000 cps to 40000 cps.

For example, in the water-in-oil cosmetic composition, when a shear rate in the range of 10 ¹ (1/S) to 10 ³ (1/S) is applied, the emulsified particles in the water-in-oil cosmetic composition are broken, and the viscosity rapidly decreases. It may be a water-in-oil cosmetic composition.

For example, the cosmetic composition may be formulated as a makeup primer, makeup base, liquid foundation, lip gloss, lip liner, twin cake, sunscreen, lotion, cream or essence, but is not necessarily limited thereto.

For example, the cosmetic applicator may be a brush.

Since the brush has to be used in the horizontal direction, compared to the conventional puff used in the vertical direction, the force is different. For example, if the force applied when using the conventional puff in the longitudinal direction is 200 g to 500 g, the force applied when using the brush in the transverse direction is 30 g to 200 g, for example, 30 g to 150 g, the magnitude of the force is greatly reduced, and thus, the hardness Even with a cosmetic carrier according to an embodiment having a low value, by using a brush, an appropriate amount of the cosmetic composition can be discharged from the cosmetic carrier to the hair of the brush with only a small force. That is, the cosmetic applicator according to one embodiment may be suitable for a brush used in the horizontal direction. (If a puff is used, it may be undesirable as excessive cosmetic composition is discharged.) Furthermore, by using a brush rather than a puff as a cosmetic applicator, it can be much easier to express sophisticated coverage and a thin layer of makeup. .

The brush bristles may have a length of 1 to 3 cm. If the length of the hair of the brush is 1 to 3 cm, the skin adhesion of the cosmetic composition is improved, and there is an advantage that it can be used by tapping. If the length of the hair of the brush is less than 1 cm, the length of the hair of the brush is short, so that the cosmetic composition is not easily taken, and the cosmetic effect is deteriorated. In particular, there is a problem in that it is difficult to take the cosmetic composition supported on the carrier. In addition, when the thickness exceeds 3 cm, it is difficult to apply the cosmetic composition evenly to the skin because the brush marks easily occur on the skin, so that the adhesion is poor.

In addition, the number of the brush bristles is 8,000 to 150,000, preferably 60,000 to 110,000. If the number of brush bristles is less than 50,000, the brush bristles are sparsely formed in the brush part, making it difficult for the brush bristles to receive force when using the brush. You can feel the stimulation.

For example, the brush bristles are artificial bristles, and may include at least one selected from the group consisting of polybutylene terephthalate, nylon, polypropylene and polyester, preferably It may include at least one selected from the group consisting of polybutylene terephthalate and nylon.

On the other hand, as the cosmetic composition applies a force in the transverse direction to the surface of the cosmetic carrier in which moisture is absorbed, friction occurs on the surface of the cosmetic carrier in contact with the applicator, unlike when using a puff that gives force in the longitudinal direction, and this frictional force is The amount, behavior, feeling of use, convenience, etc. taken of the cosmetic composition may be affected. Specifically, since the force is applied in the transverse direction rather than the longitudinal direction, when the brush is used, the cosmetic carrier inadvertently moves sideways or detaches from the container, which may negatively affect convenience and usability. Therefore, in order to prevent separation of the cosmetic carrier by brushing and properly discharge the cosmetic composition through easy brushing, the cosmetic application set according to an embodiment may further include a mesh network.

For example, the mesh network may have a woven structure with a weight of 200 g/cm ² or less.

For example, the mesh network may have a thickness of 150D (denier) or less.

In addition, in order to continuously discharge the appropriate cosmetic composition even with a small force of 30 g to 150 g, the mesh network along with the cosmetic carrier according to an embodiment must also have a structure in which it moves vertically so that the cosmetic composition can be continuously properly discharged. Therefore, unlike general fact products, the mesh network is not fixed to the edge of the container, and may be located in a non-fixed state on the cosmetic carrier absorbing moisture in the cosmetic composition. That is, the mesh network may not be fixed in the cosmetic application set.

On the other hand, the cosmetic application set may further include a cosmetic carrier accommodating container for accommodating the cosmetic carrier.

Since the cosmetic application set according to an embodiment includes both a cosmetic carrier and a cosmetic brush on which the cosmetic composition is supported, it has the advantage of being easy to carry and convenient for corrective makeup, but is not necessarily limited thereto, and the cosmetic application set includes It includes a cosmetic carrier on which the cosmetic composition is supported, and the cosmetic brush is not included in the cosmetic application set, and may be present separately.

For example, the cosmetic application set may be provided as a cosmetic container generally referred to as “fact”.

Hereinafter, the content of the present invention will be described in more detail through Examples and Comparative Examples. These examples are only presented to understand the content of the present invention, and the scope of the present invention is not limited to these examples and test examples, and modifications, substitutions and insertions commonly known in the art may be performed. and this is also included in the scope of the present invention.

Looking at Table 13, in Comparative Examples 3 to 5, the cosmetic composition is not discharged in an appropriate amount, but is non-uniformly discharged (excessive discharge), whereas in Examples 2 to 5, the cosmetic composition is discharged in an appropriate amount, It can be seen that the cosmetic carrier is not separated, and there is no air layer between the cosmetic composition, the cosmetic carrier, and the mesh, so that the cosmetic composition is uniformly discharged.

The amount of makeup delivery was measured by measuring the amount taken on the brush for 3 times of application, and the appropriate amount is 0.03 g to 0.1 g. If it is less than 0.03 g, the amount of application is small and the makeup effect is deteriorated, and if it is more than 0.1 g, it is applied excessively, and the makeup effect is deteriorated.

Although preferred embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and improvements by those skilled in the art using the basic concept of the present invention as defined in the following claims are also presented. It belongs to the scope of the right of the invention.
