Description

Technical Field

[0001] The present invention relates to an emulsified composition for makeup touch-up, a cosmetic using the same, a makeup touch-up method, and the like.

Background Art

[0002] Modern times are an era of speeding up everything, and it can be said that it is an era in which simplification of operations and speeding up of processing time are required for all living activities. The same tendency is seen in the field of cosmetics. In the 1980s, a cosmetic dosage form for shortening makeup time, typified by powder foundation, was developed. In the 1990s, multifunctional cosmetics such as rinse-in shampoo were developed. This tendency continues today, and makeup-removing cosmetics that perform face washing and cleansing simultaneously have been developed. Among a series of makeup operations, makeup touch-up, which involves removing and reapplying makeup, is an aspect in which operation shortening by such multifunctionalization of cosmetics has not been carried out. That is, after makeup cosmetics are applied, over time, they become uneven due to sebum, movement of the skin, and the like. When applying makeup on an uneven film during makeup touch-up, the state of the uneven film becomes more prominent. To avoid this, a process of removing and reapplying cosmetics is required, but such work is designed to reach foundation application through treatment in the order of cleansing cosmetics, aqueous face wash, lotion, emulsion, and under makeup.

[0003] As an attempt to simplify this step, the development of "makeup-removing cosmetics", which are lotions that also serve as aqueous face wash and cleansing, can be cited. This is a wiping lotion that contains a relatively large amount of nonionic surfactant, and directly wipes off makeup cosmetics with this wiping lotion. However, there is a limit to the ability to remove makeup cosmetics, and it is only possible to remove makeup cosmetics to an extent that does not significantly inhibit the effect of makeup, and it cannot be denied that it affects the subsequent makeup.

[0004] Furthermore, for example, Patent Document 1 proposes a cosmetic product in which an emulsified composition containing (dimethicone / vinyl dimethicone) crosspolymer, polymethylsilsesquioxane, and (HDI / trimethylol hexyllactone) crosspolymer is applied over already creased makeup, allowing it to blend with the makeup, improve the unevenness of the makeup that has been fixed in a creased state, effectively improve makeup smudging, and allow for a clean touch-up. This product allows for makeup touch-ups without the need to remove the existing makeup or apply new makeup.

[0005] Furthermore, Patent Document 2 proposes a W / O emulsified makeup touch-up composition characterized by containing a polyether-modified silicone as an emulsifier, a volatile cyclic silicone as a cleansing component, an organically modified clay mineral and / or a partially cross-linked silicone as an emulsifying stabilizer, and fatty acid dextrin and liquid oil, which combines a wiping effect and a makeup base effect. Because this provides makeup removal and base effects simultaneously, applying makeup on top of it simplifies the makeup steps in the makeup touch-up process.

[0006] However, there was a need for further development of cosmetics that could be used for quick and effective touch-ups. [Prior art documents] [Patent Documents]

Modes for Carrying Out the Invention

[0013] Hereinafter, the present invention will be described. <Emulsion Composition for Makeup Repair> One aspect of the present invention is an emulsion composition for makeup repair, comprising component (A): an oil agent capable of dispersing aggregates composed of a makeup cosmetic and sebum. This invention relates to a composition (hereinafter sometimes referred to as "the composition of the present invention") for application over makeup cosmetics on the skin to remove the makeup cosmetics and apply new makeup cosmetics.

[0014] The inventors of this invention conducted various studies in search of a cosmetic product that allows for simple and effective touch-ups. In this context, the present inventors have developed a method for dispersing aggregates consisting of makeup cosmetics and sebum. We discovered a specific oil-based agent and successfully created a makeup touch-up cosmetic using an emulsified composition containing this oil-based agent. This composition removes and homogenizes uneven makeup film caused by makeup breakdown, while simultaneously applying and forming a beautiful makeup film. Based on this knowledge, we completed the present invention.

[0015] ≪An oil capable of dispersing aggregates consisting of makeup cosmetics and sebum, component (A)≫ The composition of the present invention includes, as component (A), an oil capable of dispersing aggregates consisting of makeup cosmetics and sebum.

[0016] Whether or not an oil is capable of dispersing aggregates consisting of makeup cosmetics and sebum can be confirmed, for example, by a dispersibility evaluation method as shown in the examples below. For example, the aggregates consisting of makeup cosmetics and sebum can be mixed with the oil, and the state of dispersion can be confirmed by visual inspection or other means to determine whether or not the oil is capable of dispersing the aggregates.

[0017] One embodiment of component (A) is, but is not limited to, hydrocarbon oils, polyhydric alcohols, silicone oils, glycerin fatty acid esters, and ester oils. More specifically, examples include isododecane, dipropylene glycol, dimethicone, caprylic / capric triglyceride, cetyl 2-ethylhexanoate, dicaprylyl carbonate, and cyclohexane-1,4-dicarboxylic acid bisethoxydiglycol. The oily agent of component (A) may be one or a combination of two or more. Commercially available oily agents can be used.

[0018] In the composition of the present invention, the content of component (A) is not limited to the total composition, particularly from the viewpoint of effectively removing makeup cosmetics from the skin. For example, it may be 0.5% by mass or more, 1% by mass or more, 5% by mass or more, or 6% by mass or more, or 20% by mass or less, 15% by mass or less, 12% by mass or less, or 10% by mass or less, and may be any non-consistent combination thereof. The content may also be, for example, 0.5 to 20% by mass. When two or more types of component (A) are used in combination, the above content is the total amount of the two or more types. The blending ratio of the two or more types can be adjusted as appropriate.

[0019] ≪Surfactants in ingredient (B)≫ In the composition of the present invention, component (B) may include a surfactant. The surfactant of component (B) can be used together with component (A) to improve the dispersibility of aggregates consisting of the makeup cosmetic and sebum of component (A). The surfactant of component (B) may be one type or a combination of two or more types. Commercially available surfactants can be used as such.

[0020] One embodiment of component (B), though not limited to this, is a polyether-modified silicone surfactant. The polyether-modified silicone may be linear or branched, and may be alkyl-comodified. Specifically, examples include linear silicone polyether-modified silicone and branched silicone alkyl-comodified polyether-modified silicone, and more specifically, PEG-10 dimethicone and lauryl PEG-9 polydimethylsiloxyethyl dimethicone.

[0021] In the composition of the present invention, the content of component (B) is not limited to the total composition, particularly from the viewpoint of effective removal of makeup cosmetics from the skin, but may be, for example, 2% by mass or more, 3% by mass or more, 5% by mass or more, or 7% by mass or more, or 10% by mass or less, 9% by mass or less, 8% by mass or less, or 7.5% by mass or less, and may be any non-consistent combination thereof. Furthermore, the content may be, for example, 2 to 10% by mass. When two or more types of component (B) are used in combination, the above content is the total amount of the two or more types. The blending ratio of the two or more types can be adjusted as appropriate.

[0022] Furthermore, the mass ratio of component (A) to component (B) in the present invention, expressed as the mass ratio of component (A) to component (B) (A) / (B), is not limited from the viewpoint of effective removal of makeup cosmetics from the skin, but for example, it is preferably 1 to 50 and more preferably 3 to 20.

[0023] The dosage form of the composition of the present invention is an emulsifier type, and may be any of the following: oil-in-water (W / O) emulsifier type, water-in-oil (W / O) emulsifier type, etc., but water-in-oil emulsifier type is preferred.

[0024] The composition of the present invention is in the form of an emulsifier and comprises an aqueous phase and an oil phase. In the present invention, the aqueous phase is typically composed of water and aqueous components. Here, the aqueous components may be any components that dissolve in water at 25 to 65°C. In the present invention, the oil phase is usually composed of oily components. Here, the oily components are usually oils, but are not limited to these, and may also include components that separate from water after being suspended in water at 25-65°C and allowed to stand for 1 hour.

[0025] The internal phase ratio (mass ratio of the internal phase) in the composition of the present invention can be, for example, 2.5 to 80% by mass, 5 to 75% by mass, 10 to 70% by mass, 20 to 65% by mass, 30 to 60% by mass, 40 to 60% by mass, or 50 to 59% by mass. The composition of the present invention has a high internal phase ratio, meaning it can stably form a high internal phase content. This high internal phase content makes it easier to form a thinner, more uniform makeup film.

Foundation (see Table 1 below) Artificial sebum ((Triolein 33.3% by mass, Octyldodecyl myristate 33.3% by mass, Oleic acid 20% by mass, Squalene 13.3% by mass) See paper J. Soc. Cosmet. Chem. Jpn. 33(3)254-266(1999))

[0058] (Method for dispersing sebum pellets) 0.5g of the sebum ball prepared above and 3.8g of each oil agent listed in Table 2 were placed in a PET tube (Φ15.8×75mm) and dispersed for 1 minute using a vortex mixer (IKA, Vortex Mixer Genius3).

[0059] (Method for evaluating variance) The variance was evaluated visually based on the following evaluation indicators. (Each evaluation indicator is (A sample photograph is shown in Figure 1.) 1. Good variance 2. Although slight aggregation remains, the dispersion is generally uniform. 3. Although partially dispersed, there are clearly visible aggregates. 4. Does not disperse (remains settled)

[0060] Furthermore, for the oils of samples 8 and 9, which received a dispersibility rating of 3 using the above method, 0.2 g (4% of the total volume) of each surfactant listed in Table 2 was added and dispersed in the same manner for evaluation.

[0061] [Table 1]

[0062] (result) The evaluation results are shown in Table 2.

[0063] [Table 2]

[0064] This test selected an oil that can disperse aggregates consisting of foundation and sebum, that is, an oil that easily breaks down the aggregates and makes them uniform.

[0065] <Example 2> Removal test of sebum aggregates using a pore model (sebum aggregates applied to a pore model) Sebum aggregates were uniformly applied to black artificial leather (Beaulux Co., Ltd.) a certain number of times (0.1g on a finger and applied 3 times vertically and horizontally). Each oil or oil + surfactant was soaked into a separate puff and applied by rotating it up to 10 times to check whether the aggregates that had settled into the pores could be removed, and the correlation with Example 1 was checked.

[0066] (result) The test results are shown in Figure 2. Correlation with the results of Example 1, oils or oils + surfactants that can easily disperse sebum aggregates effectively removed foundation that had settled into pores.

[0067] <Example 3> Evaluation test of a model formulation using an oil agent capable of dispersing aggregates The pore-clogging model created above was then coated a certain number of times with foundations prepared using the formulations described in Table 3 below (Example 1 and Comparative Example 1) (0.1g was taken onto a puff and applied three times vertically and three times horizontally).

[0068] [Table 3]

[0069] (result) The test results are shown in Figure 3. When a model formulation or a comparative formulation containing 6% isododecane, an oil capable of dispersing aggregates, was applied over sebum aggregates, the model formulation was able to remove and homogenize the uneven makeup film, recreating a beautiful makeup film.

[0070] <Example 4> Examination of appropriate internal phase ratio The pore-clogging model created above was then coated with foundation prepared using the formulations described in Table 3 (Example 1 and Comparative Example 2) a certain number of times (0.1g was taken onto a puff and applied three times vertically and three times horizontally).

[0071] (result) The test results are shown in Figure 4. It was found that formulations with a high internal phase ratio form a particularly thin and uniform makeup film.

[0072] <Example 5-1> Examination of appropriate makeup tools We selected a puff that could create a uniform application film for the makeup applied on top, while also ensuring a smooth base layer of the original makeup. We predicted that there is an optimal degree of foaming (fineness of texture) and firmness for touch-ups. For the initial application, we thought a puff with a degree of foaming and firmness that allows the oil to soak in well would be good, while for the later stages of application (when patting), a puff with a lower degree of foaming and firmness would be better.

[0073] Sebum aggregates were applied to black artificial leather (Beaulux Co., Ltd.) a certain number of times (0.1g on a finger and applied 3 times vertically and horizontally). An oil agent (isododecane) was soaked in a puff and applied by rotating it up to 10 times to check if the aggregates could be removed. Two puffs with different surface conditions were used: puff 1 (for powder foundation) and puff 2 (for oil gel foundation).

[0074] (result) The test results are shown in Figure 5. Puff 1 (for powder foundation) has a surface with air bubbles and bumps, making it easy for the contents to be absorbed into the puff. Therefore, the oil was absorbed well into the puff and it was able to pick up the foundation cleanly. Puff 2 (for oil gel foundation) has a relatively smooth surface, making it difficult for the contents to be absorbed into the puff. Therefore, the oil did not soak into the puff, leaving an uneven makeup film.

[0075] The degree to which the original makeup film is removed varies depending on the amount of oil contained. It was found that a puff such as puff 1 (for powder foundation), which can contain a moderate amount of oil, is suitable for the initial application.

[0076] <Example 5-2> Examination of appropriate makeup tools A certain number of times (0.1g on a puff, applied vertically and horizontally three times each) of the foundation formulation described in Table 1 was applied to black artificial leather (Beaulux Co., Ltd.). Three puffs with different surface textures were used: puff 3 (for cushion foundation), puff 4 (for powder foundation), and puff 5 (for liquid foundation).

[0077] (result) The test results are shown in Figure 6. The degree of unevenness in foundation application varied depending on the type of puff used. Except for the puff designed for cushion foundation, unevenness was more noticeable with other puffs. It was found that puffs with low foaming and a firmer texture, such as puff 3 (for cushion foundation), were more suitable for the later stages of application.

[0078] <Example 5-3> Examination of appropriate makeup tools Based on the method described in ISO 25178, puffs 3 and 4 were measured using a KYENCE laser microscope. The surface shape (center, once) of object 5 was measured. Filtering was performed using a Gaussian filter. The measurement parameters were set as follows.

[0079] Sal, Str: s=0.20 Sxp: p=2.5%, q=50.0% Vvv: p=80.0% Vvc: p=10.0%, q=80.0% Vmp: p=10.0% Vmc: p=10.0%, q=80.0%

[0080] (result) The test results are shown in Figure 7. The cushion FD puff has a smaller surface area and lower height compared to the other two puffs. Numerically, the parameters indicating surface roughness—Sa (arithmetic mean height), Sz (maximum height), and Sdr (interface area ratio)—were all smaller than those of the other two puffs.

[0081] The optimal puff surface shape (Sa (arithmetic mean height), Sz (maximum height), Sdr (interface area ratio)) for the initial and late stages of coating was identified. The puff, with its multiple areas of different surface shapes, allows for the removal and even application of the original makeup film, while simultaneously creating a uniform coating for subsequent cosmetic applications. [Industrial applicability]

[0082] This invention can be applied to cosmetics and the like, including quasi-drugs.
