    Technical Field
    [0001] The present disclosure relates to a dry polyether based urethane foam impregnated with a cosmetic composition. Background of the Invention
    [0002] Cosmetic compositions have often been used indoors in the past. However, users have increasingly used cosmetic compositions in outdoor environments, in line with a change in lifestyle, including the generalization of leisure activities. Therefore, cosmetic compositions suitable for use and size have been increasingly in demand.
    [0003] To improve the convenience in use and the portability of cosmetic compositions, sponges made from various types of materials have been impregnated with cosmetic compositions. However, it is not easy to find an excellent material in terms of durability, filling capacity, impregnation capacity and unloading capacity. Therefore, there has been a need for the development of a material suitable for impregnation with a cosmetic composition. Related State of the Art References
    [0004] (Patent Document 1) Korean Patent Publication No. 10-2009-0100643. Detailed Description Technical problem
    [0005] A technical problem to be solved by the present invention is to provide a dry polyether based urethane foam suitable for impregnation with a cosmetic composition. Technical Solution

    [0013] Figure 5 is a table with results of the durability assessment (Test Example 1). Best Way to Carry Out the Invention
    [0014] In one aspect, a dry polyether based urethane foam impregnated with a cosmetic composition is provided. In another aspect, the polyether-based urethane dry foam can function as a support on which a cosmetic composition is supported and retained.
    [0015] As used herein, "urethane foam" means a solidified and foamed polyurethane resin, and may also be referred to as "foamed urethane".
    [0016] As used herein, "durability" means the degree to which a urethane foam remains as it is without melting, tearing or swelling when impregnated with a cosmetic composition and stored at a predetermined temperature for a predetermined time. As used herein, "filling capacity" means the ability of a urethane foam to fill with a cosmetic composition, and can be represented as the time required to fill a predetermined amount of cosmetic composition. As used herein, "discharging capacity" means an amount of cosmetic composition discharged when removing the cosmetic composition from a urethane foam impregnated therewith. When removing the cosmetic composition, it is required that the cosmetic composition is discharged in an adequate amount, not too much, but not too little.
    [0017] Urethane foams can be classified into a polyester-based urethane foam and a polyether-based urethane foam. A polyether-based urethane foam is more resistant to moisture compared to a polyester-based urethane foam and therefore does not break easily under high humidity conditions and shows high stability. In addition, a polyether-based urethane foam has a larger cell structure compared to a polyester-based urethane foam and therefore has improved air permeability, a feeling of softness, smoothness and flexibility. In addition, a polyether-based urethane foam has a reduced production cost and is therefore more cost-effective compared to a polyester-based urethane foam.
    [0018] In accordance with one aspect of the present disclosure, dry urethane foam based on polyether serves for use in impregnation with a cosmetic composition, and has a different constitution from the constitution of the conventional cosmetic applicator (also called "cushion" or “Cosmetic sponge”). In particular, the “cosmetic applicator” serves to apply a cosmetic composition to the user's skin during use. In other words, a cosmetic applicator is intended to transfer a cosmetic agent onto the skin, by allowing the applicator itself to be covered with a cosmetic agent and to contact the user's skin, and therefore does not contain any cosmetic composition. in itself. In contrast, the material for impregnating with a cosmetic agent according to the present disclosure is impregnated with a cosmetic agent and retains the cosmetic agent itself before use (i.e., requires durability and filling capacity). Then, another cosmetic applicator must be coated with an adequate amount of cosmetic composition upon use (that is, it requires the ability to unload). That is, the material for impregnating with a cosmetic agent according to the present invention is not in direct contact with the skin, but is only impregnated with a cosmetic agent and, therefore, requires the use of another applicator. Therefore, the “cosmetic applicator”, that is, “cushion” does not allow the easy application of a cosmetic composition on the skin of the user in use if the cosmetic composition seeps into the deep inner portion of the sponge. Therefore, it is preferable that a cosmetic agent barely infiltrates the deep inner portion of the sponge. On the other hand, the foam impregnated with a cosmetic composition according to the present invention is a material for impregnation with a cosmetic agent and requires its impregnation with a cosmetic agent, as an essential function. As disclosed above, the foam according to the present description is clearly different from the conventional cosmetic applicator (pad).
    [0019] Fig. 3 shows a product including material impregnated with a cosmetic composition according to the present description. It can be seen that the product may also include a separate cosmetic applicator, in addition to the material for impregnation with a cosmetic composition.
    [0020] Polyether based urethane foams can be classified into dry polyether based urethane foams and wet polyether based urethane foams, depending on the manufacturing processes. Dry sponges are obtained by inserting foam blocks in a gas chamber and injecting a gas into it, to make the cells explode and open. Thus, such a dry process requires high precision because the cell structure and the hardness of the resulting product will depend on the amount of gas injected. Wet sponges are obtained by introducing the blocks into a container filled with a liquid (chemical) phase and by opening the cells by chemical action. Such a wet process is used mainly for the production of soft foam products and is expensive due to the use of different liquid phases.
    [0021] A dry polyether based urethane foam generally has a larger pore size, compared to a wet polyether based urethane foam. While a wet polyether based urethane foam is expanded by a wet process and shows hydrophilic surface properties, a dry polyether based urethane foam shows oleophilic surface properties. A dry polyether based urethane foam is commercially available as EZ93N® (trademark). Compared to a wet polyether-based urethane foam, a dry polyether-based urethane foam has greater filling and discharging capacity when a cosmetic composition is supported therein and is therefore suitable for impregnation with a cosmetic composition . Therefore, the present invention provides a dry polyether based urethane foam having unique properties necessary for a material for impregnation with a cosmetic composition, not for a cosmetic applicator.
    [0022] According to one embodiment of the present invention, the dry polyether based urethane foam can have a hardness of at least 5, at least 10, at least 15, at least 20, at least 25, at least 30, at least 35, at least 40 or at least 45, as determined by an ASKER Type F durometer. According to another embodiment of the present invention, the dry polyether based urethane foam can have a hardness of at most 80, in the maximum 75, maximum 70, maximum 65, maximum 60, maximum 55, maximum 50 or maximum 45, as determined by an ASKER Type F durometer. According to another embodiment of the present invention, the dry foam of polyether-based urethane can have a hardness of 5-80, in particular 10-70, more particularly 3060, and even more particularly 35-55, as determined by ASKER Type F durometer. The hardness range above the dry foam of polyether based urethane means the hardness of dry polyether based urethane foam r before being impregnated with a cosmetic composition. When the dry polyether based urethane foam has the hardness range defined above before being impregnated with a cosmetic composition, it shows excellent durability and is highly effective in terms of filling capacity and discharge capacity.
    [0023] The dry polyether based urethane foam according to the present invention can have a pore number of at least 70, at least 75, at least 80, at least 85, at least 88 or at least 90 per inch (ie, ppi (pore per inch). According to another embodiment of the present invention, the dry polyether based urethane foam according to the present invention can have a maximum pore number of 110, a maximum of 108, a maximum of 105, a maximum of 103 or a maximum of 100 per inch. According to yet another embodiment of the present invention, the dry polyether based urethane foam according to the present invention can have a pore number of 70-110, in particular 80-105 and more particularly 85-103 per inch. When the urethane foam has a pore number of less than 70 ppi [27 pores per centimeter], it shows low elasticity, does not provide any comfort in use, and has difficulty controlling the flow of a cosmetic composition. When the urethane foam has a pore number greater than 110 ppi [44 pores per centimeter], it has a low durability and provides an unsatisfactory feeling when using the impregnated cosmetic composition.
    [0024] According to an embodiment of the present invention, the urethane foam can have a cross-linked structure. In this case, the urethane foam can be uniformly impregnated with a cosmetic composition with ease in a higher impregnation ratio.
    [0025] In this context, the urethane foam having a cross-linked structure is obtained by subjecting a urethane foam to a separate cross-linking process. A lattice structure is also referred to as a three-dimensional network structure. The cross-linked structure has a modified network structure obtained by cross-linking the membranes (walls) of balloon-shaped cells after foaming, and allows not only the permeation of air, but also the absorption / discharge of liquid phases. “Crosslinking” is a process in which a foam structure is changed to a mesh structure depending on the use. In the case of a foam sponge, this refers to the cross-linking of air cells through the opening of its walls. Such a crosslinking process is shown in Fig. 4. Therefore, the crosslinked structure according to one embodiment of the present disclosure is completely different from the conventional foam structure in which three-dimensional membrane structures are formed inside the sponge, so that a cosmetic agent cannot penetrate the deep inner portion of the sponge. The cross-linked structure is also different from the “cover” of the upper part of a urethane foam support with a mesh, cloth, non-woven fabric, etc.
    [0026] According to another embodiment, the urethane foam may have an open cell structure.
    [0027] In general, a urethane foam obtained by foaming and aging has a closed-cell or semi-open cell structure. When a urethane foam has a closed cell structure, air cells are trapped in urethane, so it is not easy to impregnate the foam with a low viscosity emulsified cosmetic composition. Therefore, a urethane foam having an open cell structure is preferred. According to a particular embodiment of the present invention, a urethane foam can have a complete open cell structure through the aforementioned cross-linking process, whereby the cell surfaces are opened to leave only the structure.
    [0028] Dry polyether based urethane foam having a cross-linked structure according to the present invention has less smoothness compared to a wet urethane foam. Due to the characteristics of a cross-linked structure, the dry polyether-based urethane foam having an open cell structure, in which the cell surfaces are open may have low smoothness. However, since the foam should not be in direct contact with the skin, it is not necessary for the foam to be highly smooth. The dry polyether-based urethane foam having such a cross-linked structure has greater filling capacity and discharge capacity and is therefore suitable as a material for impregnation with a cosmetic composition.
    [0029] As used herein, “pore number” refers to the number of pores per inch and can be a value obtained by measuring and averaging the pore numbers present in a 1-inch line based on WI- QA-14 (ASTM standards).
    [0030] As the ppi number increases, the pore size decreases. Since such a number of pores is determined by visual inspection, pore recognition depends on the condition of the pores, approved in different ways by different countries. For example, Visual Counting Methods (ppi check) from Japan, USA and Europe are shown in the following Table 1. Table 1. Visual Counting Methods (ppi check)

    [0031] Here, the US Visual Counting Method is used to determine the ppi. Therefore, the ppi of the urethane foam according to an aspect of the present invention is about 30 ppi different from its ppi, determined using Japan's Visual Counting Method.
    [0032] Here, the cell size is the average of measurements determined by an optical microscope (Nikon Eclipse 80i).
    [0033] According to one embodiment, the dry polyether based urethane foam can have a density of at least 1 [16.02 kg / m3], at least 1.3 [20.82 kg / m3], at least minus 1.5 [24.03 kg / m3] or at least 1.8 pcf (pounds per cubic foot) [28.84 kg / m3]. According to another embodiment, the dry polyether based urethane foam can have a density of a maximum of 3 [48.06 kg / m3], a maximum of 2.8 [44.85 kg / m3], a maximum of 2 , 5 [40.05 kg / m3], a maximum of 2.3 [36.84 kg / m3] or a maximum of 2 pcf [32.04 kg / m3]. According to yet another embodiment, the dry polyether based urethane foam can have a density of 1-3 pcf [16.02-48.06 kg / m3], particularly 1-2 pcf [16.02-32, 04 kg / m3]. When the urethane foam has a density of less than 1 pcf [16.02 kg / m3], an excessively large amount of cosmetic composition can be discharged, thereby interrupting wearing comfort. On the other hand, when the urethane foam has a density greater than 3 pcf [48.06 kg / m3], the pores in which a cosmetic composition can be incorporated are insufficient, so effective impregnation with a cosmetic composition cannot be performed . Here, the density can be determined, for example, based on the ASTM D3547 standard.
    [0034] According to one embodiment, a dry polyether based urethane foam with a diameter of at least 4 cm, at least 4.2 cm, at least 4.4 cm, or at least 4.6 cm and in the maximum 5 cm, maximum 4.9 cm or maximum 4.8 cm, and a thickness of at least 0.5 cm, at least 0.6 cm or at least 0.8 cm and a maximum of 2 cm 1.8 cm, maximum 1.5 cm, maximum 1.3 cm or maximum up to 1 cm, can allow at least 10 g, at least 13 g or at least 15 g and at most 20 g to be filled, a maximum of 18 g or a maximum of 16 g of a cosmetic composition that has a viscosity of 5,000-15,000 cP (centipoise) [5,000-15,000 mPa s] within a time of at least 3 s, or at least 4 s, and, a maximum of 10 s, a maximum of 8 s or a maximum of 6 s. According to another embodiment, when a dry polyether based urethane foam having a diameter of at least 4 cm, at least 4.2 cm, at least 4.4 cm, or at least 4.6 cm and at most 5 cm, maximum 4.8 cm or maximum 4.8 cm, and a thickness of at least 0.5 cm, at least 0.6 cm or at least 0.8 cm and a maximum of 2 cm 1.8 cm, maximum 1.5 cm, maximum 1.3 cm or maximum 1 cm supports a cosmetic composition having a viscosity of 5,000-15,000 cP, it is possible to discharge a cosmetic composition in a unit quantity of at least 0 , 2 g, at least 0.3 g or at least 0.4 g and at most 0.7 g, at most 0.6 g or at most 0.5 g.
    [0035] According to yet another embodiment, the cosmetic composition applicable to the dry urethane foam based on polyester for impregnation may be a liquid cosmetic composition, particularly an emulsified cosmetic composition, and more particularly an emulsified cosmetic composition of the W / O type (water in oil) or type O / W (oil in water).
    [0036] According to yet another embodiment, an emulsified cosmetic composition can have a viscosity of 5,000-15,000 cP, in particular 7,000-13,000 cP, more particularly 8,000-12,000 cP, and even more particularly 9,000-11,000 cP. When an emulsified cosmetic composition has a viscosity within the range defined above, it is possible to achieve the desired effects according to the present invention, and the dry polyether based urethane foam can provide excellent properties. In addition, it is appropriate for an emulsified cosmetic composition to have a viscosity within the range defined above in view of the cost-benefit ratio. According to yet another embodiment, the viscosity can be determined by a viscometer, for example, LVDV-II + PRO or RVDV III ULTRA set to No 63 or No 64 spindle and a spindle speed of 5 rpm or 12 rpm, but not limited to these. The viscosity value can vary according to the systems used for the measurement, the number of spindles, rpm or others.
    [0037] In another aspect, the present invention provides a cosmetic product including a dry polyether based urethane foam impregnated with a cosmetic composition. Since the cosmetic product includes the dry polyether based urethane foam to which a cosmetic composition is applied according to an embodiment of the present invention, it is possible to obtain a high filling capacity of the cosmetic composition, to discharge an appropriate amount of the composition cosmetic when in use and maintain high durability for a long time. According to an embodiment of the present invention, the cosmetic composition can include a cosmetic composition for skin care and a cosmetic composition for makeup. Particularly, the cosmetic composition can be formulated as a makeup primer, makeup base, foundation, powder, duocake, lipstick, gloss, eye shadow and eyebrow, concealer, lip liner, blush, UV protector, lotion, cream or essence and, more particularly, makeup primer, makeup base, liquid or solid foundation, powder, duocake, lipstick, gloss, eye shadow and eyebrow, concealer or blush, but not limited to these. According to another embodiment of the present description, the cosmetic product can be supplied as a cosmetic container, generally called "compact", which includes a container that has a bottom portion, in which the polyether-based urethane foam is received. , and a top portion such as a lid on which a mirror or the like can be glued. According to yet another embodiment of the present invention, when a cosmetic product that includes a dry polyether-based urethane foam impregnated with a UV protector is supplied in the form of a compact, it is possible to use and transport the compact more conveniently, in compared to another UV protective cosmetic product, and provide a cooling effect.
    [0038] The examples, comparative examples, preparation examples and test examples will now be described to describe the construction and effects of the present invention in greater detail. The following examples, comparative examples, preparation examples and test examples are for illustrative purposes only and are not intended to limit the scope of the present disclosure. Examples and Comparative Examples
    [0039] A dry polyether based urethane foam and a wet polyether based urethane foam obtained by the methods generally known to those skilled in the art are provided. The properties of each type of urethane foam are shown in the following Table 2. The densities in Table 2 are measured based on the ASTM D3547 standard. Table 2
    Test Example 1. Durability Assessment
    [0040] The dry polyether-based urethane foam of the Example and the wet polyether-based urethane foam of the Comparative Example are evaluated for durability. The test method will be described in detail below.
    [0041] Each type of urethane foam (Example and Comparative Example) is shaped into a circular shape, which has a size of 48 mm in diameter x 10 mm in thickness, and is impregnated with 15 g of the same cosmetic composition with a viscosity of 10,000 cP. Then, each type of foam is stored at 55 ° C for 7 days and its condition is checked. The results are shown in Figure 5. Viscosity can be determined by a viscometer, for example, LVDV-II + PRO or RVDV III ULTRA set to No 63 or No 64 spindle and a spindle speed of 5 rpm or 12 rpm.
    [0042] As can be seen in the table in Figure 5, the dry polyether-based urethane foam retains its shape even after being impregnated with a cosmetic composition and, thus, presents a high durability. Test Example 2. Filling Capacity Assessment
    [0043] Dry urethane foam based on polyether and wet urethane foam based on polyether are evaluated for filling capacity. In particular, the hardness of each type of foam is measured by an ASKER Type F durometer before being impregnated with a cosmetic composition. Then, each type of foam is shaped into a circular shape, which has a size of 48 mm in diameter x 10 mm in thickness, and the time required for each type of foam to be impregnated with 15 g of the same cosmetic composition with a viscosity of 10,000 cP is determined. The viscosity of the cosmetic composition is determined by LVDV-II + PRO set for No. 63 spindle and a spindle rotation speed of 5 rpm. The results are shown in the following Table 4 and Figure 1. Table 4

    [0044] As can be seen from the results above, when the dry polyether-based urethane foam shows a hardness of 30-55 on the ASKER type F durometer, the cosmetic composition requires a filling time as short as 10 s or less. On the other hand, wet polyether-based urethane foam requires a longer filling time as the hardness increases, which suggests that it has a low filling capacity. Test Example 3. Evaluation of the Discharge Capacity (1) Investigation of the Optimal Discharge Quantity
    [0045] First, to investigate the amount of a suitable cosmetic composition as a unit quantity of discharge, 50 people are led to apply different amounts of cosmetic composition and evaluate each of the following items from which the ideal amount can be derived, classifying them as grade 1 to grade 9 (higher grade represents better quality). The results are shown in the following Table 5. “Applicability” refers to a degree of satisfaction with the amount applied to the skin, “cosmetic effect” means whether or not the cosmetic composition shows excellent coverage on the skin without agglomeration and allows for uniform makeup within a suitable time, “comfort” refers to a degree of comfort in using the cosmetic composition without the need to pick up many times, while allowing easy control of the amount applied and “satisfaction” refers to a degree of overall satisfaction . Table 5

    [0046] As can be seen from the results above, when the amount of unitary application of a cosmetic composition is 0.3-0.5 g, in particular it is about 0.5 g, a high cosmetic effect, comfort and satisfaction are obtained. Therefore, it can be seen that when a cosmetic composition is taken once, 0.3-0.5 g, particularly about 0.5 g, is suitable as a unit application amount. (2) Evaluation of the Ability to Download
    [0047] Dry urethane foam based on polyether and wet urethane foam based on polyether are evaluated for their ability to discharge. In particular, the hardness of each type of foam is measured by an ASKER Type F durometer before being impregnated with a cosmetic composition. Then, each type of foam is impregnated with a sufficient amount of the same cosmetic composition with a viscosity of 10,000 cP, and the amount (g) of cosmetic composition discharged when taking the cosmetic composition at once using a pad. The results are shown in the following Table 6 and Figure 2. Table 6


    [0048] As can be seen from the results above, both dry polyether-based urethane foam and wet polyether-based urethane foam tend to show a decrease in the amount of cosmetic composition discharged to the pillow, depending on increases hardness. When the dry polyether-based urethane foam has a hardness of 30-60, especially 35-50, as measured by an ASKER Type F durometer, it shows a unit discharge amount of 0.3-0.5 g, resulting in a excellent discharge capacity. On the other hand, when the wet polyether-based urethane foam has a hardness of 35 or higher, as measured by an ASKER type F durometer, the amount of unit discharge decreases significantly, resulting in poor discharge capacity.
    [0049] In summary, as can be seen from all of the above results, dry polyether based urethane foam and wet polyether based urethane foam have the durability, filling capacity and ability to discharge as shown in Table 7 below. Table 7

    [0050] As can be seen from the above, the dry polyether based urethane foam with excellent durability, filling capacity and discharge capacity for a cosmetic composition is suitable for use in impregnation with a cosmetic composition.
