Make-up cosmetic composition having improved feeling of use}

This specification describes a makeup cosmetic composition with improved feeling of use.

The global market for so-called cushion compact products, which are made by absorbing the contents of basic functional cosmetics such as sunscreen and makeup base and makeup functions such as foundation into a special sponge material and putting them in a compact container, is expanding globally. Since cushion compacts are preferred by consumers who seek simplicity in use while having multiple functions, it is necessary to provide not only a makeup effect but also a high UV protection effect by using only the cushion compact.

Therefore, the cosmetic composition used in the cushion compact needs to have a high UV blocking effect, adhere evenly to the skin, and have excellent spreadability to enhance the makeup properties.

It is necessary to contain a high content of organic and inorganic sunscreen ingredients in order to show a high UV blocking effect, but the former has poor compatibility with commonly used silicone oils, and the latter has limitations that adversely affect pigment dispersion stability. There is.

Accordingly, the pigment can be stably dispersed to provide improved feeling of use such as adhesion and spreadability, and has a low viscosity that can be absorbed and used in materials such as sponges, while providing excellent stability as a whole composition and high UV protection. There is a need to implement compositions that exhibit effectiveness.

It can provide a refreshing feeling of use. If the viscosity is below the above range, the cosmetic composition is not uniformly impregnated throughout the entire impregnating material and sinks to the bottom, making use inconvenient, or there is a risk that the cosmetic composition may leak outside the product during storage. In addition, if the viscosity exceeds the above range, it is difficult to impregnate the cosmetic composition into the impregnating material, and a sticky and heavy feeling may be felt when applied to the skin.

In one embodiment, the composition according to this example may be a water-in-oil (W/O) type emulsion composition. The cosmetic composition is a water-in-oil type and can be applied to cosmetics of various formulations such as flowable cosmetics, such as makeup primer, makeup base, skin cover, foundation, lipstick, lip gloss, liquid eye shadow, eye brow, liquid concealer, and liquid blusher.

It may be, but is not limited to this.

For example, the moisturizer includes erythritol, xylitol, maltitol, propylene glycol, sorbitol, polyglycerin, polyethylene glycol, 1,2-pentanediol, isopropylene glycol, amino acid, sodium lactate, sodium pyrrolidone carboxylate, Psiloglucan, quince seed, carrageenan, pectin, mannan, curdlan, galactan, dermatan sulfate, glycogen, keratan sulfate, chondroitin, mucoitin sulfate, keratin sulfate, locust bean gum, succinoglycan, calonimic acid.

In one embodiment, the cosmetic composition according to one embodiment of the present invention may be provided by being impregnated inside an impregnating material.

The impregnating material can be used by discharging the material contained therein into a separate applicator.

In one embodiment, the impregnating material may be a foam (or sponge) for carrying the cosmetic composition, but is not limited thereto. The foam can be any foam material that can be used, but specific properties such as specific material, cell structure, cell size, number of pores, density, and hardness can be selected depending on the physical properties required as an impregnation material.

Physical properties required for the impregnating material include, for example, water absorption, filling ability, carrying capacity, durability, and discharge ability.

The absorbency means that the impregnating material absorbs the cosmetic composition and supports it evenly throughout the entire interior of the impregnating material. High absorbency means excellent compatibility between the impregnating material and the cosmetic composition, and the higher the absorbency, the more it is possible to suppress evaporation of the cosmetic composition when stored under high temperature conditions.

The filling ability means that when the cosmetic composition is filled into the impregnating material, the cosmetic composition is easily and uniformly supported throughout the entire inside of the impregnating material. Excellent filling ability means that the cosmetic composition is filled uniformly at a high speed when the cosmetic composition is filled under the same conditions and pressure.

The carrying capacity refers to the ability of the impregnating material to retain and maintain the cosmetic composition. Excellent carrying capacity means maintaining the cosmetic composition in a uniformly supported state for a long period of time. The carrying capacity of this impregnating material is distinct from that of being temporarily taken out of the applicator to deliver the cosmetic composition and that of being temporarily buried in the applicator.

The durability includes chemical durability and physical durability. Chemical durability refers to the property of maintaining the initial state without causing damage such as melting or tearing or deformation such as expansion when the impregnating material is left at a certain temperature for a certain period of time with a cosmetic composition supported thereon. Physical durability refers to the property of withstanding physical stimulation of the impregnating material, for example, the pressure and friction applied to the impregnating material when repeatedly contacting and applying pressure to the impregnating material with an applicator to extract the cosmetic composition. Therefore, high durability means that the impregnating material is maintained without deformation or damage for a long period of time under certain conditions in a state impregnated with a cosmetic composition, and that the original state can be maintained without damage or deformation of the impregnating material even when repeatedly subjected to physical friction and pressure by the applicator. it means.

The discharge ability refers to the ability of the cosmetic composition supported inside the impregnating material to be discharged in an appropriate amount when used. For example, the discharge capacity can be expressed as the amount of cosmetic composition deposited on the applicator by contacting the applicator with the impregnating material at a certain pressure. If the discharge capacity is too high or too low, the cosmetic composition may be excessively smeared or only a small amount may be smeared, making use inconvenient. Therefore, it is desirable to have an appropriate discharge capacity so that an appropriate amount of the cosmetic composition can be discharged according to the pressure applied to the impregnating material.

The physical properties required for the above-described impregnation material may vary depending on specific characteristics such as material, cell structure, cell size, cell number, density, and hardness of the impregnation material.

In one embodiment, the impregnation material may be porous foam.

The materials of the foam include synthetic resin sponge, polyethylene, polypropylene, polystyrene, polyurethane, acrylonitrile-butadiene rubber (NBR), urethane, foamed urethane, latex, butadiene rubber (BR), and styrene-butadiene. Rubber (SBR), Natural Rubber, Chloroprene Rubber (CR), Isoprene Rubber (IIR), Isoprene Rubber (IR), Vulcanized Ethylene-Propylene Rubber (EPR), Polysulfide Rubber ), silicone rubber, fluororubber, urethane rubber, acrylic rubber, EPDM (Ethylene propylene diene monomer) rubber, polyvinyl alcohol (PVA), ethylene vinyl acetate ( Various materials such as EVA) and NR (Nitrile Rubber) can be used. In one example, the foam may be dry polyether-based urethane foam, but is not limited thereto.

The cell structure of the foam is open cell, semi-open cell, closed cell, or reticulated structure to satisfy the physical properties required as an impregnation material. These may be formed individually or two or more of them may be combined.

The cosmetic composition is impregnated within the pores of the impregnating material and discharged through an applicator. In this case, if the cell structure of the foam with formed pores is a closed cell, impregnation and discharge of the cosmetic composition cannot be achieved. Therefore, the impregnating material preferably has an open cell, semi-open cell, or network-type structure, except when it is 100% closed cell, and this cell structure may include some closed cells depending on the manufacturing of the foam. Most preferably, the absorption capacity, support capacity, and discharge capacity of the cosmetic composition can be increased by using foam with a network structure. The open-cell, semi-open-cell, and network-type foams can be confirmed by cutting a cross section and taking a photo.

The cell size of the foam may be related to the absorbency, filling capacity, carrying capacity, durability, and discharge capacity of the cosmetic composition supported in the foam, and is also related to the feeling of use of the foam itself. The cell size of the foam may be an average value measured with an optical microscope (NIKON ECLIPSE 80i). Cell size can be any level sufficient to achieve the intended effect of the invention. For example, the cell size may be 100 μm to 900 μm, specifically 300 μm to 700 μm. If the cell size is less than the above range, it may not be easy to discharge the cosmetic composition even if the carrying capacity is high. If the cell size exceeds the above range, the carrying capacity of the cosmetic composition may decrease and discharge may be excessively large, and the surface of the foam may be rough. As it may become sticky, the feeling of use may not be smooth when discharged into the applicator.

The density of the foam may be related to the extent to which the cosmetic composition can be absorbed and supported inside the foam and whether it can be discharged. For example, the density may be 1.0 to 3.0 pcf (pounds per cubic feet), specifically 1.5 to 2.5 pcf. If the density of the foam is less than 1.0, too much cosmetic composition may be smeared, which may reduce usability. If the density is more than 3.0, there are insufficient pores into which the cosmetic composition can be impregnated, making it difficult to effectively impregnate the cosmetic composition. .

The number of pores in the foam is related to the number of cells and is related to the physical properties of the impregnating material itself, such as ductility, elasticity, flexibility, soft feeling, and fluffy feeling. The number of pores refers to the number of pores per square inch of the foam. For example, the number of pores may be 40 to 120 ppi (the number of pores in 1 inch), and more preferably 60 to 100 ppi. If the number of pores in the foam is less than 40 ppi, the elasticity of the foam decreases and it is difficult to control the fluidity of the cosmetic composition, and if the number of pores exceeds 120 ppi, durability during use may decrease.

The hardness of the foam is measured with a DUROMETER HARDNESS meter (Type F) manufactured by ASKER, and refers to the hardness before the composition is supported on the foam. The hardness is a parameter related to the discharge ability of the cosmetic composition supported in the foam, and if the hardness is too high or too low, the discharge may be too much or too little. For example, the hardness may range from 50 to 95 based on an ASKER hardness machine Type F. If the hardness is less than 50, the cosmetic composition impregnated in the polyurethane foam may be excessively discharged when taking out the cosmetic composition using an applicator, and if the hardness is over 95 and too hard, the cosmetic composition may not be easily discharged. there is.

In one embodiment, the foam may include film-processed foam or flock-processed foam. The film-processed foam is a polymer foam such as rubber, polyvinyl, or polyurethane coated with a film, and the cell size is generally smaller than that of the foam before film processing. The flock processed foam may be obtained by attaching fibers to polymer foam. The fiber may be one or more selected from the group consisting of cotton, acrylic, polyamide, nylon, polyester, silk and rayon, and specifically cotton, acrylic, polyamide, nylon, polyester, silk, cotton and acrylic, cotton and May include rayon, nylon and polyester and cotton, acrylic and polyester.

The diameter and thickness of the foam may vary depending on the cosmetic container. The diameter of the foam may be 30 mm to 70 mm or 40 mm to 60 mm, and the discharge amount of the impregnated cosmetic composition may be appropriate within the above range. The thickness of the foam may be 1 mm to 50 mm, for example, 5 mm to 30 mm, 6 mm to 29 mm, 7 mm to 28 mm, 8 mm to 27 mm, 9 mm to 26 mm, or 10 mm to 25 mm. If the thickness is less than the above range, the amount of the cosmetic composition supported may be small, and if it exceeds the above range, it may be difficult to discharge the contents without the remaining amount of the contents during use.

In one embodiment of the present invention, a cosmetic may be provided including the cosmetic composition according to the above-described embodiment of the present invention and an impregnating material impregnated with the cosmetic composition.

The cosmetic may further include a container storing an impregnating material impregnated with the cosmetic composition. The container may be a compact type container.

The foam may be separable from the container, and the user may fill the container from which the foam is separated with the cosmetic composition as desired and then use the foam by combining the foam. Additionally, users can replace only the foam.

The cosmetic may further include an impregnating material and a separate applicator.

In one embodiment, the container can accommodate the impregnating material and applicator.

In one embodiment, the cosmetic product may be used by placing a cosmetic composition impregnated in an impregnating material on an applicator and applying it to an application target. In this case, the cosmetic composition does not stick to the hands when applied, making it easy to use and hygienic.

The material and shape of the applicator are not limited, but when applying the cosmetic composition to the skin, it should be applied smoothly without leaving lines or dots, so the pores are fine, and since it touches the skin directly, it is desirable to have a soft and cushiony feeling. . In one example, the applicator may use a foam material. When applying a cosmetic composition to the skin with the applicator, the applicator temporarily retains the cosmetic composition, which may cause a wet and unpleasant feeling when applied, and the cosmetic composition that has been exposed to the outside while temporarily absorbed in the applicator may be applied to the skin again. There is a possibility. Therefore, it is advantageous for the applicator not to excessively absorb the cosmetic composition, and it is preferably made of a material that does not expand when the cosmetic composition is applied. In addition, the applicator must be able to easily remove the cosmetic composition impregnated with the impregnating material, be easily applied to the skin, and provide an excellent feeling of use when applied to the skin.

In one embodiment, the applicator is made of acrylonitrile butadiene rubber (NBR), styrene butadiene rubber (SBR), natural rubber (NR), polyvinyl chloride, polyethylene, ethylene-vinylacetate butyl rubber (EVA), latex, silicone, Styrene-isoprene-styrene (SIS), styrene-ethylene-butylene-styrene (SEBS), polyvinyl alcohol (PVA), nitrile rubber, butyl rubber, chloroprene rubber (neoprene®, polyolefin, polyurethane, and ether-based polyurethane) It may be a foam manufactured from one or more selected from the group consisting of a mixture of polyurethane and ester-based polyurethane, for example, acrylonitrile butadiene rubber or styrene butadiene rubber.

Hereinafter, the present invention will be described in detail with reference to examples, comparative examples, and test examples. These are only presented as examples to explain the present invention in more detail, and it is clear to those skilled in the art that the scope of the present invention is not limited by these Examples, Comparative Examples, and Test Examples.

100 g of the compositions of the above Examples and Comparative Examples were stored in a thermostat at 30°C for 24 hours, and then the viscosity was read using Brookfield Viscometer Model DV-II+, when measured for 1 minute at spindle No. 64, 12 rpm. The results are shown in Table 2.

2. Measurement of UV protection index

2-1. Measurement of sunprotection factor (SPF)

The sunprotection factor (SPF) was measured according to the UV protection effect measurement method and standards set forth in the Cosmetics Act for the ultraviolet SPF/UVA protection test.

For the UV SPF blocking test, subjects suitable for the test purpose are selected through medical history and skin condition diagnosis, irradiated with ultraviolet rays using a Multiport Solar UV simulator (601-300w) on the back area where the product was not applied, and 16-24 hours later without application. Determine the MED of the area. The cosmetic compositions of Examples and Comparative Examples were uniformly applied to the skin of three healthy women at a thickness of 2 mg/cm2 on the test subjects' backs. Based on the MED of the non-coated product, determine the MED and SPF of the standard sample and test product by irradiating ultraviolet rays. The UV protection factor (SPFi) for each subject is calculated according to the formula in Equation 1, and the UV protection factor of the sample is determined using the arithmetic mean value.

[Equation 1]

UV protection factor for each subject (SPF _i ) = Minimum erythema amount in the area where the product was applied (MED _p )/Minimum erythema amount in the area where the product was not applied (MED _u )

2-2. UVA Blocking rating (PA) measurement

The ultraviolet UVA blocking test was conducted according to the test method presented in the Japan Cosmetic Association's UVA blocking effect measurement method (JCIA, 2012). This test method uses the International Organization for Standardization's UVA blocking effect measurement method (ISO24442, 2011). The cosmetic compositions of the standard sample and examples and comparative examples were uniformly applied to the subject's back in an amount of 2 mg/cm2 and stabilized for 15 minutes, and then irradiated with ultraviolet A based on the non-coated MPPDD to obtain the standard sample and test product. Determine MPPDD and PFA. The minimum continuous immediate darkening amount (MPPD) was determined, and using the determined value, the UV A blocking index was calculated using Equation 2 below and the average value was obtained. Ultraviolet A protection levels are classified as shown in Table 2 below.

[Equation 2]

PFA calculation method = (Minimum continuous immediate blackening amount (MPPD _p ) on the area where the sample was applied)/(Minimum continuous immediate blackening amount on the area where the sample was not applied (MPPD _u ))

UVA protection factor (PFA) UVA protection grade (PA) UVA blocking effect 2 or more but less than 4 PA+ has exist

There are very many 4 or more but less than 8 PA++ 8 or more but less than 16 PA+++ 16 or more PA++++

3. Dispersion stability evaluation

10 g of each of the Example and Comparative Example compositions were taken and each sample was placed in a cycle chamber that circulated between -10°C and 45°C for 24 hours, and then the change in pigment dispersibility of the formulation was visually observed to confirm stability. The results are shown in Table 3 and Figure 1.

[ Test example 4] Impregnation material Manufacturing of cosmetics containing

Cosmetics were manufactured by impregnating foam with the cosmetic compositions of Examples and Comparative Examples. The foam is a dry polyether-based urethane foam material, with a pore count of 80 ppi, a density of 1.8 lb/ft3, a hardness of 70 before impregnating the composition (based on ASKER hardness machine Type F), and a cell size (cell size) of 70%. size) of 500㎛, diameter of 40mm, and thickness of 5mm were used.

[ Test example 5] Impregnation material Sensory evaluation of cosmetics containing

1. Sensory evaluation of adhesion and spreadability

The forearms (forearms) of 30 female panelists aged 25 to 40 were washed in a constant temperature and humidity room, and 50 ㎕ each of Hera Aquabolic Lotion and Hera Sunmate Excellence Sun Cream were applied. After that, a 0.5cm*1.5cm wide rectangle is marked with a black line on the forearm, and the foam containing the compositions of the examples and comparative examples is pressed into the rectangle with the hand, touched once, and then applied in an amount of 0.5g that comes out on the hand. did. Each applied composition was rolled 15 times and tapped 20 times by hand, and then the composition of Example 1 was first evaluated, and the remaining samples were compared with the composition of Example 1. Scored. The applicability sensory evaluation score is the average of the results of evaluating the degree to which it spreads smoothly and evenly without resistance on the initial skin, and the adhesion sensory evaluation score refers to the degree to which each composition is well fixed on the skin when applied by patting it on the skin and the degree to which each composition above is applied. This is the average of the results obtained by evaluating the overall level of the composition's absorption into the skin after 3 minutes of application. The lowest score of the adhesion and spreadability sensory evaluation score was 0 points, and the highest score was 16 points. The results are shown in Table 3.

2. Simple adhesion test

The forearms (forearms) of 30 female panelists aged 25 to 40 were washed in a constant temperature and humidity room, and 50 ㎕ each of Hera Aquabolic Lotion and Hera Sunmate Excellence Sun Cream were applied. After that, a rectangle measuring 0.5cm*1.5cm in size is marked with a black line on the forearm, and the foam containing the compositions of the examples and comparative examples is pressed with the hand and touched once, and 0.5g of the amount that comes out on the hand is taken and applied to the forearm. applied to. Then, using the hand, the number of rolling required until each applied composition was all fixed was measured. The results are shown in Table 3.

From the results in Table 3, it can be seen that the compositions of Examples 1 and 2 have excellent UV blocking effects, excellent adhesion and spreadability, and excellent dispersion stability. In the case of Comparative Example 1, which does not contain a sunscreen, the dispersibility is excellent but there is no UV blocking effect. In the case of using only one type of emulsifier of the examples of the present invention (Comparative Examples 2 and 4) or not including a dispersant (Comparative Example 3- 5), it can be seen that pigment bands are formed due to poor dispersion stability.
