Description

Technology Field

[0001] The present invention relates to a water-in-oil cosmetic composition that has improved makeup transfer resistance and excellent gloss. Background Technology

[0002] General emulsion cosmetic products are evaluated for quality based on factors such as spreadability, color payoff, gloss, longevity, stability over time, and skin safety. Therefore, a superior product applies smoothly and lightly to the skin, offers excellent color payoff, and lasts for a long time. Additionally, it must not be washed off by external factors such as sebum, sweat, or water, and must remain safe when applied to the skin without significant changes in physical properties during long-term storage or use. However, due to the nature of their formulations, emulsion cosmetic products have the disadvantage of easily smudging or transferring even during low-intensity daily activities, which leads to a reduction in the effectiveness of the makeup.

[0003] Until now, most water-in-oil and water-in-oil cosmetic compositions with excellent longevity have contained a large amount of volatile oil in the continuous phase, which causes the oil to evaporate and form a film or leave only the coloring agent. Consequently, they have the disadvantage of leaving a cosmetic effect that is dry and lacks gloss when applied to the skin.

[0004] In other words, existing technology had limitations in providing a makeup effect with excellent gloss while suppressing makeup transfer, and there is a need for the development of products that improve upon these limitations.

[0005] Against this background, the inventors confirmed that by simultaneously containing an ester-based oil and a film-forming agent, it is possible to produce a cosmetic composition that suppresses makeup transfer while providing excellent gloss, and thus completed the present invention. The problem to be solved

[0006] The objective of the present invention is to provide a water-in-oil cosmetic composition that improves makeup transfer and provides excellent gloss. Specifically, the invention provides a water-in-oil cosmetic composition comprising oil and a film-forming agent. means of solving the problem

[0007] To solve the above problem, the present invention provides a water-in-oil cosmetic composition comprising an oil and a film-forming agent, wherein the oil is an ester-based oil and the film-forming agent is one or more selected from the group consisting of silicate polymers, silsesquioxane polymers, and acrylate silicone polymers.

[0008] In the present invention, the ester-based oil is Tridecyl Trimellitate, Diisostearyl Malate, Methyl Hydrogenated Rosinate, Isopropyl Palmitate, Octyldodecyl Myristate, Isopropyl Myristate, Butyloctyl Salicylate, Coco-Caprylate / Caprate, Hexyl Laurate, Dicaprylyl Carbonate, Butylene Glycol Dicaprylate / Dicaprate, Decyl Cocoate, Dicaprylyl Carbonate It may be one or more selected from the group consisting of carbonate, cetyl ethylhexanoate, triethylhexanoin, dicetearyl dimer dilinoleate, caprylic / capric triglyceride, polyglyceryl-2 triisostearate, propylene glycol dibenzoate, and pentaerythrityl tetraisostearate, but is not limited thereto. Preferably, the ester oil may be tridecyl trimellitate, diisostearyl maleate, or methylhydrogenated rosinate, but is not limited thereto.

[0009] In the present invention, the ester-based oil may have a refractive index of 1.46 or higher. The "refractive index" refers to a value indicating the degree of speed reduction relative to vacuum when light passes through the oil phase of the composition. If the refractive index of the ester-based oil is less than 1.46, the gloss enhancement ability decreases, and there may be a problem with the excellent gloss quality characteristic.

[0010] In one embodiment of the present invention, the ester-based oil may be included in an amount of 3 to 15 weight%, for example, 3 to 12 weight%, 3 to 10 weight%, 3 to 8 weight%, or 3 to 6 weight% based on the total weight of the cosmetic composition. If the content of the ester-based oil is less than 3 weight%, the glossiness enhancing power decreases, which may cause problems with the excellent glossiness characteristic, and if it exceeds 15 weight%, the emulsification stability of the cosmetic composition may decrease.

[0011] In the present invention, the "film-forming agent" is a component that forms a film on the surface of the skin and can be used interchangeably with the "film-forming agent." The film-forming agent may be added for the purpose of forming a thin film on the skin to prevent makeup from being easily removed and to provide a soft and smooth feel.

[0012] In the present invention, the film-forming agent may be one or more selected from the group consisting of silicate polymers, silsesquioxane polymers, and acrylate silicone polymers. For example, the silicate polymer may be trimethylsiloxysilicate, phenylpropyldimethylsiloxysilicate, trimethylsiloxysilicate / dimethicone crosspolymer, dimethicone / vinyltrimethylsiloxysilicate crosspolymer, or trimethylsiloxysilicate / dimethiconol crosspolymer, but is not limited thereto. In addition, the silsesquioxane polymer may be polypropylsilsesquioxane, polymethylsilsesquioxane, polyphenylsilsesquioxane, or dimethicone / silsesquioxane copolymer, but is not limited thereto. The acrylate silicone polymer may be an acrylate / dimethicone copolymer, an acrylate / ethylhexyl acrylate / dimethicone methacrylate copolymer, or an acrylate / polytrimethylsiloxymethacrylate copolymer, but is not limited thereto.In addition, they can have different physical properties depending on the degree of bonding.

[0013] In one embodiment of the present invention, the film-forming agent may be included in an amount of 1 to 10 weight%, for example, 1 to 8 weight%, 2 to 8 weight%, or 3 to 7 weight% based on the total weight of the cosmetic composition. If the content of the film-forming agent is less than 1 weight%, there may be a problem where the film formation is insufficient and the characteristic of improving transferability disappears, and if it exceeds 10 weight%, there may be a problem in terms of usability, such as a foreign body sensation, due to excessive film formation.

[0014] The oil-in-water cosmetic composition according to the present invention may include one or more film-forming agents selected from the group consisting of ester-based oils, silicate polymers, silsesquioxane polymers, and acrylate silicone polymers in the oil phase. In this case, after the volatile components evaporate, the ester-based oil may impart a glossy appearance, and one or more film-forming agents selected from the group consisting of silicate polymers, silsesquioxane polymers, and acrylate silicone polymers may form a persistent film on the skin to suppress makeup transfer.

[0015] The present invention can provide a cosmetic composition with excellent adhesion and gloss by including the oil and film-forming agent in an appropriate ratio. In one embodiment of the present invention, the weight ratio of the oil and film-forming agent may be 15:1 to 1:13, 14:1 to 1:12, 13:1 to 1:11, 12:1 to 1:10, 11:1 to 1:9, 10:1 to 1:8, 9:1 to 1:7, 8:1 to 1:6, 7:1 to 1:5, 6:1 to 1:4, 5:1 to 1:3, 4:1 to 1:2, 3:1 to 1:2, or 2:1 to 1:1, but is not limited thereto.

[0016] Meanwhile, the water-in-oil cosmetic composition of the present invention may further include additives commonly used in the field, such as preservatives, stabilizers, surfactants, thickeners, solvents, moisturizers, emollients, UV absorbers, preservatives, disinfectants, emulsifiers, antioxidants, pH adjusters, organic and inorganic pigments, fragrances, cooling agents, or limiting agents.

[0017] In one embodiment of the present invention, the cosmetic composition may further include a thickening agent. Preferably, the thickening agent may be a wax-based thickening agent, and the wax-based thickening agent may be glyceryl behenate / eicosadioate, tribehenin, poly C10-30 alkyl acrylate, etc., but is not limited thereto.

[0018] In one embodiment of the present invention, the thickener may be included in an amount of 0.5 to 5 weight%, for example, 0.5 to 4 weight%, 0.5 to 3 weight%, or 0.5 to 2 weight% based on the total weight of the cosmetic composition. If the content of the thickener is less than 0.5 weight%, transfer may not be improved and a gloss-maintaining effect may not be achieved. If the content of the thickener exceeds 5 weight%, the emulsification stability of the cosmetic composition may decrease, and problems regarding usability may occur, such as the product hardening on the skin and causing a foreign body sensation.

[0019] The water-in-oil cosmetic composition according to the present invention may further include a wax-based thickening agent in the oil phase, in which case gloss is maintained and transfer resistance can be improved.

[0020] The cosmetic composition according to the present invention can be prepared in any formulation conventionally manufactured in the art. For example, the water-in-oil cosmetic composition can be formulated in the form of basic cosmetics such as skin toner, lotion, essence, cream, sun lotion, sun cream, etc., and makeup cosmetics such as lipstick, lip gloss, lip tint, primer, foundation, base, etc., but is not limited thereto.

[0022] In addition, the present invention relates to a method for manufacturing the aforementioned cosmetic composition.

[0023] The cosmetic composition according to the present invention can be prepared by the step of preparing a mixture of oil and a film-forming agent, and then mixing other ingredients used in general cosmetic compositions, or by the step of mixing the oil, the film-forming agent, and other ingredients together.

[0024] In one embodiment of the present invention, a thickening agent may be additionally used to prepare a mixture of oil and film-forming agent.

[0026] The advantages and features of the present invention and the methods for achieving them will become clear by referring to the embodiments described in detail below. However, the present invention is not limited to the embodiments disclosed below but may be implemented in various different forms. These embodiments are provided merely to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention, and the present invention is defined only by the scope of the claims. Effects of the invention

[0027] The water-in-oil cosmetic composition according to the present invention can provide excellent gloss while suppressing makeup transfer compared to conventional cosmetics by increasing adhesion. Accordingly, it is possible to provide a cosmetic composition in which transfer and gloss, which are opposing properties, are simultaneously improved. Brief explanation of the drawing

The obtained mixture and the oil phase (A) of components 1 to 9 of [Table 9] above were introduced into an emulsification tank capable of stirring, heated to 70°C to 80°C, and stirred with a homomixer at a speed of 1,500 rpm to 2,500 rpm for 5 to 10 minutes to be uniformly mixed. At this time, the powder was sufficiently stirred using a disperser before being incorporated into the emulsification tank. The aqueous phase (C) of components 12 to 15 was introduced into an aqueous dissolution tank capable of temperature control and stirring, and while maintaining the temperature at 60°C to 70°C, it was stirred to be uniformly dissolved and mixed. Then, the aqueous phase of the prepared aqueous dissolution tank was introduced into the oil phase of a vacuum emulsification tank and mixed by stirring with a homo mixer at a speed of 1,500 rpm to 3,600 rpm for 5 to 10 minutes, and then cooled to 30°C to 35°C. Afterward, the mixture was mixed by stirring with a homo mixer at a speed of 1,500 rpm to 3,600 rpm for 2 to 3 minutes in the vacuum emulsification tank. After stirring, the foundation was finally manufactured through cooling to 30°C and degassing.

[0079] Experimental Example 4: Comparison of Smearing of Water-in-Oil Cosmetic Compositions

[0080] An internal clinical test was conducted to compare the transfer of Example 13 and Comparative Example 4 in [Table 9]. Three subjects were tested, and a certain amount of the product was applied to the forearm, a mask was attached, and the mask was photographed after 4 hours. The captured images were analyzed using the Image-Pro V.10 program.

[0081] As a result of comparing the adhesion area of ​​Comparative Example 4 and Example 13, it was confirmed that the adhesion area of ​​the composition according to Example 13 was reduced by approximately 72% compared to Comparative Example 4 (see FIG. 1 and 2).

[0083] Experimental Example 5: Comparison of Glossiness of Water-in-Oil Cosmetic Compositions

[0084] To compare the glossiness of Example 13 and Comparative Example 4 in [Table 9], a certain amount of the water-in-oil cosmetic composition was applied to the face, and an evaluation of glossiness improvement was conducted before and immediately after application. There were three subjects, and glossiness was measured using a 'Glossymeter GL-200', which is a device for measuring the glossiness of the skin surface. The amount of white light reflected from the skin at an angle of incidence of 60 degrees was measured, and the measurement was conducted using a specific formula to minimize the influence of skin color, and the results were compared and presented.

[0085] As a result of comparing the improvement in glossiness between Comparative Example 4 and Example 13, it was confirmed that the glossiness of the composition according to Example 13 increased by approximately 63.6% compared to Comparative Example 4 (see Fig. 3).
