Abstract
Description
[Technical Field]
[0001] The present invention relates to an emulsion cosmetic composition that contains an oil phase, an aqueous phase, an ionic polymer, and an oil gelling agent and that has excellent stability at low temperatures, and a method for producing the same. [Background technology]
[0002] Emulsion cosmetic compositions have the advantage of providing a moisturizing feeling for skin / toners due to their low viscosity, and of providing a shielding effect and a moisturizing feeling for skin due to the high amount of oil blended. Because these emulsion cosmetic compositions contain a high oil content, they are prepared by blending a large amount of surfactant and undergoing a high-pressure emulsification process, or by incorporating a large amount of lecithin or polyglycerin-based surfactant to create a two-layer emulsion.
[0003] Among these, the method of blending a large amount of surfactant and undergoing a high-pressure emulsification process has the disadvantages of requiring the application of high energy to produce the contents and requiring a higher level of surfactant to be blended than with oil.
[0004] In the case of a method that contains a large amount of lecithin or polyglycerin surfactant and has a two-layer emulsion structure, the emulsion particles tend to coalesce at low temperatures, making it difficult to maintain the initial appearance and quality. Specifically, the fluidity of the emulsion particles adjacent to the gas phase decreases at low temperatures, inducing phase inversion of the surfactant, which causes the oil in the top layer to coalesce, resulting in changes in the initial appearance and quality of use.
[0005] In order to overcome the limitations of the conventional techniques as described above, the present inventors discovered that by mixing an ionic polymer capable of forming a coacervate with an oil gelling agent to form a thin film of an oil phase on top of an aqueous phase, it is possible to improve low-temperature stability while maintaining emulsion particles, and thus completed the present invention.

DETAILED DESCRIPTION OF THE INVENTION
[0026] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will now be described in detail so that those skilled in the art can easily practice the present invention.
[0027] Unless otherwise defined, all technical terms used in the present invention are used in the sense that they are commonly understood by those skilled in the art in the technical field related to the present invention. In addition, methods and materials similar to or equivalent to those described as preferred methods and materials in the present invention are also included in the scope of the present invention.
[0028] The constitution of the emulsion cosmetic composition of the present invention will be explained in more detail below.
[0029] Emulsified cosmetic composition The emulsified cosmetic composition according to the present invention comprises an oil phase and an aqueous phase, and the oil phase forms a thin film on top of the aqueous phase to maintain emulsion particles.
[0030] The content of the oil phase may be 5 wt % to 10 wt % of the total weight of the cosmetic composition, or may be 6 wt % or more, 7 wt % or more, or 8 wt % or more.
[0031] It may be present at 9% by weight or less, 8% by weight or less, or 7% by weight or less.
[0032] The range may also be between any one of the lower limit values and any one of the upper limit values.
[0033] If the content of the oil phase exceeds 10% by weight, the excessive use of oil may result in a decrease in the feel or stability of the product, and if it is less than 5% by weight, the amount of oil blended is so small that the functionality of the cosmetic product cannot be fully ensured and the skin cannot be sufficiently moisturized.
[0034] The oil phase and the aqueous phase of the emulsion cosmetic composition according to the present invention may contain substances having opposite electric potentials. This allows the oil phase and the aqueous phase to exhibit opposite electric potentials, and coacervates can be formed between the oil phase and the aqueous phase due to the interaction between the charges caused by the opposite electric potentials. This allows the oil phase to form a thin film on top of the aqueous phase, and the oil phase to exist in a particulate form, thereby enabling the formulation of an emulsion cosmetic composition with excellent stability at low temperatures.
[0035] In the present invention, the term "coacervate" means that a cationic polymer and an anionic polymer are temporarily electrostatically bonded together.
[0036] The oil phase of the emulsion cosmetic composition according to the present invention may contain a cationic polymer. The cationic polymer may be any polymer that has positive electrical properties and can form a temporary coacervate with the anionic polymer, without any limitations.
[0037] The cationic polymer may include a natural synthetic polymer, and specifically may include at least one selected from the group consisting of chitosan, cationic cellulose, cationic guar, cationic polysaccharide, silicone-based polymers containing amino groups, polyquaternium, and combinations thereof. Preferably, the cationic polymer may include, but is not limited to, a silicone-based polymer containing amino groups.
[0038] The silicone polymer containing an amino group may include at least one selected from the group consisting of bis-amodimethicone, amodimethicone, aminopropyl dimethicone, aminoethylaminopropyl dimethicone, amino bispropyl dimethicone, amodimethicone hydroxystearate, and combinations thereof, and preferably includes, but is not limited to, aminopropyl dimethicone.
[0039] The cationic polymer may be contained in an amount of more than 0 wt % to 1 wt % or less based on the total weight of the cosmetic composition, or may be contained in an amount of more than 0.1 wt %, more than 0.2 wt %, more than 0.3 wt %, more than 0.4 wt %, or more than 0.5 wt %. It may be contained at 0.9 wt% or less, 0.8 wt% or less, 0.7 wt% or less, 0.6 wt% or less, or 0.5 wt% or less.
[0040] The range may also be between any one of the lower limit values and any one of the upper limit values.
[0041] If the content of the cationic polymer exceeds 1 wt%, coalescence occurs between the cationic polymers, resulting in a problem of deterioration in the appearance and quality of the contents. If the content is 0 wt% or less, the cationic polymer cannot sufficiently form a coacervate with the anionic polymer, making it impossible to maintain the stability of the contents.
[0042] The oil phase of the emulsion cosmetic composition according to the present invention may contain an oil gelling agent, which prevents coalescence of emulsion particles at low temperatures, enhances the stability of the contents, and maintains the initial appearance and quality of the product.
[0043] Examples of the oil gelling agent include ester-based oils and urethane-based copolymers. Specific examples include Castor Oil / IPDI Copolymer and Caprylic / Capric Triglyceride, available commercially under the name Estogel M from PolymerExpert, Caprylic / Capric Triglyceride, Hydrogenated Poly(C6-20 Olefin) and HDI / Trimethylol Hexyllactone Crosspolymer, available commercially under the name Oilkemia 5S CC Polymer from Lubrizol, and Caprylic / Capric Triglyceride and Polyurethane-79, available commercially under the name Crystal Clear Wax from TKB Trading, LLC. Polyurethane-79), and combinations thereof.
[0044] The ester-based oil may include, but is not limited to, caprylic / capric triglyceride.
[0045] The urethane-based copolymer may include, but is not limited to, one or more selected from the group consisting of castor oil / IPDI copolymer, HDI / trimethylolhexyl lactone crosspolymer, polyurethane-79, and combinations thereof.
[0046] The oil gelling agent may be contained in an amount of more than 0 wt % to 1 wt % or less based on the total weight of the cosmetic composition, or may be contained in an amount of more than 0.1 wt %, more than 0.2 wt %, more than 0.3 wt %, more than 0.4 wt %, or more than 0.5 wt %. It may be contained at 0.9 wt% or less, 0.8 wt% or less, 0.7 wt% or less, 0.6 wt% or less, or 0.5 wt% or less.
[0047] The range may also be between any one of the lower limit values and any one of the upper limit values.
[0048] If the content of the oil gelling agent exceeds 1% by weight, the hardness increases and emulsified particles cannot be dispersed. If the content is 0% by weight or less, the coacervation of the ionic polymer cannot be promoted, and the stabilization of the contents cannot be maintained.
[0049] The particle size of the oil phase portion of the emulsion cosmetic composition according to the present invention may be 10 μm to 20 μm, or may be 11 μm or more, 12 μm or more, 13 μm or more, 14 μm or more, or 15 μm or more, It may be 19 μm or less, 18 μm or less, 17 μm or less, 16 μm or less, or 15 μm or less.
[0050] The range may also be between any one of the lower limit values and any one of the upper limit values.
[0051] If the particle size of the emulsified cosmetic composition exceeds 20 μm, there is a risk that the emulsion particles will not be sufficiently formed, and if it is less than 10 μm, the emulsion particles may coalesce at low temperatures, which may impair the stability of the product.
[0052] The oil phase of the emulsion cosmetic composition according to the present invention may further contain a wax or a fatty alcohol.
[0053] The wax may be a wax commonly used in cosmetic compositions, and specifically may include, but is not limited to, one or more waxes selected from the group consisting of ceresin wax, polyethylene wax, microcrystalline wax, paraffin wax, ozokerite, carnauba wax, candelilla wax, and combinations thereof.
[0054] The fatty alcohol may be a fatty alcohol commonly used in cosmetic compositions and may be solid at room temperature, and may specifically include, but is not limited to, one or more selected from the group consisting of myristyl alcohol, cetyl alcohol, stearyl alcohol, and combinations thereof.
[0055] The aqueous phase of the emulsion cosmetic composition according to the present invention may contain an anionic polymer. The anionic polymer may be any polymer that has negative electrical properties and can form a temporary coacervate with the cationic polymer, without limitation.
[0056] The anionic polymer may include, but is not limited to, a Carbomer.
[0057] The anionic polymer may be contained in an amount of more than 0 wt % to 0.5 wt % or less, or more than 0.01 wt %, more than 0.03 wt %, more than 0.05 wt %, more than 0.07 wt %, more than 0.09 wt %, more than 0.1 wt %, more than 0.2 wt %, or more than 0.3 wt %, based on the total weight of the cosmetic composition. It may be contained at 0.49% by weight or less, 0.47% by weight or less, 0.45% by weight or less, 0.43% by weight or less, 0.41% by weight or less, 0.4% by weight or less, 0.3% by weight or less, or 0.2% by weight or less.
[0058] The range may also be between any one of the lower limit values and any one of the upper limit values.
[0059] If the content of the anionic polymer exceeds 0.5 wt%, there are problems such as a decrease in production efficiency, appearance and quality of the contents, and if it is 0 wt% or less, it is unable to form a sufficient coacervate with the cationic polymer, making it impossible to maintain the stability of the contents.
[0060] The aqueous phase may further contain a polyol, etc. The polyol may be a polyol commonly used in cosmetic compositions, specifically, sorbitol, polyethylene glycol (PEG), polypropylene glycol (PPG), dipropylene glycol, propylene glycol, 1,3-butylene glycol, glycerin, propanediol, ethylhexanediol, 1,2-hexanediol, PEG / PPG / polybutylene glycol-8 / 5 / 3 glycerin, ethylhexylglycerin, pentylene glycol, etc. Glycol) and combinations thereof.
[0061] The emulsion cosmetic composition according to the present invention can maintain formulation stability without the addition of a surfactant. Conventionally, emulsion cosmetic compositions containing a high oil content have used surfactants as an essential component to stabilize the formulation. However, surfactants can cause the cosmetic composition to feel sticky or induce skin irritation. According to the present invention, by mixing an ionic polymer capable of forming a coacervate with an oil gelling agent, it is possible to stabilize the formulation without the use of a surfactant.
[0062] The emulsion cosmetic composition according to the present invention may further contain one or more components selected from the group consisting of all kinds of components that can be used in ordinary cosmetics, whitening components, anti-wrinkle components, fragrances, preservatives, antioxidants, anti-discoloration agents, and combinations thereof, within the scope that does not impair the object of the present invention.
[0063] Method for producing emulsion cosmetic composition The method for producing an emulsion cosmetic composition according to the present invention can include: (1) a step of producing an oil phase containing a cationic polymer and an oil gelling agent; (2) a step of producing an aqueous phase containing an anionic polymer; and (3) a step of stirring the oil phase and the aqueous phase.
[0064] The cationic polymer, oil gelling agent, and anionic polymer used in the method for producing the emulsion cosmetic composition have been described above in detail, and therefore, detailed description thereof will be omitted below.
[0065] The method for producing the emulsion cosmetic composition can include the step of (1) producing an oil phase containing a cationic polymer and an oil gelling agent.
[0066] The step of preparing the oil phase can be carried out by completely dissolving the components using a paddle mixer at 80 to 110°C. Since the oil phase contains an oil gelling agent, a dissolving process is essential.
[0067] The method for producing the emulsion cosmetic composition can include the step (2) of producing an aqueous phase containing an anionic polymer.
[0068] The step of preparing the aqueous phase can be carried out by stirring the components using a homomixer at a high temperature (about 75°C). The aqueous phase requires dispersion of a thickener and a high-temperature emulsification process, so heating conditions are required. The method for producing the emulsion cosmetic composition can include the step (3) of stirring the oil phase and the aqueous phase.
[0069] The step of stirring the oil phase and the aqueous phase can be carried out by a conventional method for stirring the oil phase and the aqueous phase, such as slowly adding the oil phase to the aqueous phase while stirring.
[0070] The present invention will be described in more detail with reference to the following examples and test examples. It will be obvious to those skilled in the art that the following examples and test examples are merely provided for illustrative purposes in order to more specifically explain the present invention, and that the scope of the present invention should not be construed as being limited by these examples and test examples.
[0071] [Examples 1 to 3 and Comparative Examples 1 to 5] According to the formulations shown in Tables 1 and 2 below, emulsion cosmetic compositions of Examples 1 to 3 and Comparative Examples 1 to 5 were produced.
[0072] Specifically, the components contained in the oil phase in the composition ratios shown in Tables 1 and 2 were placed in a reactor and heated thoroughly at 110°C using a paddle mixer (manufacturer: Global Lab, model name: SS-20) until completely dissolved, producing the oil phase. Separately, the components contained in the aqueous phase in the composition ratios shown in Tables 1 and 2 were heated to 75°C, and then stirred at 9000 rpm for 3 minutes using a homomixer (manufacturer: Primix, model name: Mark2 2.5) to produce the aqueous phase.
[0073] The oil phase was slowly added to the aqueous phase while stirring at a low speed of 3000 rpm for 3 minutes to prepare an emulsified cosmetic composition.
[0074] In Comparative Example 2, the prepared oil phase was added to the prepared aqueous phase, and hydrogenated lecithin was also added as a surfactant.
[0075] For stability evaluation, a small amount of oil-soluble dye (types: malachite extract, lithospermum erythrorhizon root extract) was added to Examples 1 to 3 and Comparative Examples 1 to 5.

[0078] * Oilkemia 5S CC polymer: Caprylic / Capric Triglyceride, Hydrogenated Poly(C6-20 Olefin) and HDI / Trimethylol Hexyllactone Crosspolymer * Crystal Clear Wax: Caprylic / Capric Triglyceride and Polyurethane-79 *EstoGel M: Castor Oil / IPDI Copolymer and Caprylic / Capric Triglyceride *Oleogy LEOT: Octyldodecanol, Dibutyl Ethylhexanoyl Glutamide and Dibutyl Lauroyl Glutamide *HDXP: Dextrin Palmitate *Carbopol 981: Carbomer *SEPINOV WEO: Hydroxyethyl Acrylate / Sodium Acryloyldimethyl Taurate Copolymer
[0079] [Test Example 1] pH evaluation The pH of the emulsion cosmetic compositions of Examples 1 to 3 and Comparative Examples 1 to 5 was measured and is summarized in Table 3.
[0080] [Table 3]
[0081] To be marketable as a cosmetic, the pH must be 3.0 to 9.0, and it was confirmed that the pH of all of Examples 1 to 3 and Comparative Examples 1 to 5 satisfied this range.
[0082] [Test Example 2] Evaluation of particle size The particle sizes of the emulsion cosmetic compositions of Example 1 and Comparative Examples 1 and 2 were measured using an optical microscope (manufacturer: Nikon Instruments Korea Co., Ltd., model name: Microscope 80i, ×200 magnification), and the results for Example 1 and Comparative Example 2 are shown in Figures 2 and 3.
[0083] The particle sizes of Example 1 and Comparative Example 1 were measured at the 10 μm to 20 μm level, and those of Comparative Example 2 were measured at the 1 μm to 10 μm level. Comparative Example 2 contained a surfactant but did not contain a cationic polymer, an anionic polymer, or an oil gelling agent, and therefore it was confirmed that small particle sizes were formed.
[0084] [Test Example 3] Appearance and stability evaluation of emulsion cosmetic compositions To confirm the appearance of the emulsion cosmetic compositions, the emulsion cosmetic compositions of Examples 1 to 3 and Comparative Examples 1 to 5 were placed in transparent plastic containers, and the appearances were observed. The results are shown in Table 4.
[0085] To confirm the stability of the emulsion cosmetic compositions, the emulsion cosmetic compositions of Examples 1 to 3 and Comparative Examples 1 to 5 were placed in transparent plastic containers and stored under CYC (-15 to 45°C) temperature conditions for 4 weeks, and the degree of separation over time was observed, and the results are shown in Table 4. A photograph of Example 1 taken after 4 weeks is shown in Figure 4, and a photograph of Comparative Example 1 taken after 1 week is shown on the left side of Figure 5.
[0086] [Table 4]
[0087] Regarding appearance, Examples 1 to 3, in which the oil phase contained an oil gelling agent including a cationic polymer, an ester oil, and a urethane copolymer, and the aqueous phase contained a carbomer, exhibited a two-layer emulsion state, while Comparative Examples 3 and 4, in which a different oil gelling agent was used, exhibited a single-layer emulsion state, and Comparative Examples 1 and 2, in which no oil gelling agent was used, and Comparative Example 5, in which the oil gelling agent was used, exhibited a two-layer emulsion state.
[0088] With regard to stability, only Examples 1 to 3, which contained the above ingredients, had good stability, while Comparative Examples 1 to 5, which contained none of the above ingredients, experienced separation. For example, Example 1, which contained all of the cationic polymer, anionic polymer, and oil gelling agent, did not experience separation under any temperature conditions (CYC, -15°C, 30°C, 37°C, 45°C) even after 4 weeks, and no change in color was observed. This confirmed that the emulsion cosmetic composition according to the present invention stably maintains its initial appearance and quality even at low temperatures.
[0089] However, in the case of Comparative Example 1, which contained a cationic polymer and an anionic polymer but no oil gelling agent, separation did not occur initially, but separation began to occur as the temperature increased, and it was confirmed that the initial appearance and quality could not be maintained after one week. Comparative Example 2, which contained a surfactant but no cationic polymer, anionic polymer, or oil gelling agent, also separated at low temperatures, and it was confirmed that the initial appearance and quality could not be maintained.
