Abstract
Description
cosmetic composition
[0001] The present invention relates to a cosmetic composition, which provides similar properties and usability to O / W emulsified creams manufactured by including a conventional high-temperature heating step, while being capable of being manufactured in an environmentally friendly manner.
[0002]
[0003] Currently, commercially available creams are broadly categorized into gel creams and general emulsified creams based on their formulation. Gel creams are manufactured by stabilizing the oil phase within a three-dimensional hydrogel network using high-molecular-weight polymers that are both water-dispersible and oil-encapsulating. General emulsified creams are manufactured by emulsifying fatty acids, fatty alcohols, butter waxes, and emulsifiers with high melting points (over 60°C) at high temperatures (over 60-70°C). This method has been widely used in the cosmetics industry from the past to the present.
[0004]
[0005] Gel creams are difficult to stabilize in large amounts in oil-based formulations, making it difficult to provide a nourishing sensation or lasting moisturization. Furthermore, gel creams using hydrophobic alkyl polymers also struggle to stabilize large amounts of oil-based products. If a stable gel cream containing a large amount of oil is attempted, the polymer content inevitably increases, resulting in negative effects such as stickiness and greasiness.
[0006] While adding high-hardness butter or wax to standard emulsified creams can impart a nutritious feel, these products suffer from limitations such as increased hardness over time, relatively poor spreadability, and limited stability under refrigerated conditions. Furthermore, the use of high-melting-point emulsifiers, fatty acids, or fatty alcohols necessitates high-energy, high-temperature processing.
[0007] As carbon emissions are regulated in each country in accordance with the recent climate change agreement and companies begin to actively engage in ESG activities, the cosmetics industry is being asked to reduce energy and carbon emissions in its emulsified cream manufacturing methods. However, converting to low-energy methods is difficult.
[0008] Against this backdrop, the inventors of the present invention have made diligent efforts to provide an O / W emulsified cream cosmetic composition having excellent nutritional value and moisturizing power through an environmentally friendly manufacturing method, and have completed the present invention by confirming improvement in physical properties and usability by applying an oleogel containing low-melting-point butter.
[0009] A cosmetic composition comprising a sucrose ester having an HLB of 15 or higher, a polyol containing three or more hydroxyl groups (-OH), and an oily component is provided.
[0010] Another object of the present invention is to provide a manufacturing method for manufacturing an O / W emulsified cream that is environmentally friendly and uses less energy.
[0011] Another object of the present invention is to provide a cosmetic composition manufactured by the above manufacturing method.
[0012]
[0013] This is explained in detail as follows. Meanwhile, each description and embodiment disclosed in the present invention can also be applied to each other description and embodiment. In other words, all combinations of the various elements disclosed in the present invention fall within the scope of the present invention. Furthermore, the scope of the present invention should not be considered limited by the specific descriptions described below.
[0014]
[0015] In order to achieve the above-mentioned purpose, a cosmetic composition comprising a sucrose ester having an HLB of 15 or more, a polyol containing three or more hydroxyl groups (-OH), and an oily component is provided.
[0016] In order to achieve the above-mentioned purpose, a method for producing an emulsified cream formulation cosmetic composition is provided, comprising: a step of producing an O / D gel phase including a surfactant phase and an oil phase component; and a step of producing an O / W emulsion by adding an aqueous phase component to the O / D gel phase.
[0017] In order to achieve the aforementioned purpose, a skin moisturizing method is provided, comprising a step of applying to the skin a cosmetic composition comprising a sucrose ester having an HLB of 15 or higher, a polyol containing three or more hydroxyl groups (-OH), and an oily component.
[0018]
[0019] Hereinafter, the present invention will be described in more detail.
[0020]
[0021] The term "eco-friendly manufacturing method" of the present invention may be a manufacturing method that can be manufactured with lower energy consumption compared to conventional manufacturing methods and reduces carbon dioxide emissions.
[0022]
[0023] The term "emulsified cream formulation cosmetic composition" of the present invention refers to a cosmetic composition having an O / W (oil-in-water) emulsified cream structure, which means a cosmetic composition having a formulation in which an oil phase component is dispersed in the form of fine particles in an aqueous phase component, such that the aqueous phase component forms the exterior (continuous phase) and the oil phase component forms the interior (dispersed phase).
[0024] As described above, the conventional manufacturing method for obtaining the above-mentioned emulsified cream formulation cosmetic composition has the disadvantage of requiring high energy for manufacturing because it requires a process of heating the oily component and the emulsifier at a high temperature, and when high-hardness butter or wax is included, it can provide a nutritious feeling, but in this case, there are formulation limitations such as the hardness increasing over time, the relatively poor spreadability, and the limitation of low stability under refrigerated conditions.
[0025] The method for manufacturing an emulsified cream cosmetic composition of the present invention solves these problems.
[0026]
[0027] The term "O / D (Oil / Detergent phase) gel phase" of the present invention may be a gel phase formed by forming a continuous phase in which the oil component is a dispersed phase and a phase including a surfactant and a polyol is a continuous phase.
[0028]
[0029] The above surfactant phase may include at least one selected from the group consisting of a surfactant having an HLB of 15 or higher and a polyol.
[0030]
[0031] The term "surfactant having an HLB of 15 or higher" of the present invention is an emulsifier, which may be advantageous in dispersing oil in water due to its strong hydrophilicity. Specifically, the surfactant having an HLB of 15 or higher may be a polyglyceryl ester or a sucrose ester.
[0032] The polyglyceryl ester may include polyglyceryl-10 ester, the sucrose ester may include sucrose stearate, and more preferably, the surfactant having an HLB of 15 or higher may be sucrose stearate.
[0033] If the HLB of the surfactant is less than 15, oleogel may not be formed, causing separation of the oil component and polyol, which may cause problems with formulation stability.
[0034]
[0035] The above surfactant may be included in an amount of 0.1 to 10 wt% based on the total weight of the cosmetic composition.
[0036] Specifically, if the surfactant is included in an amount of less than 0.1 wt% based on the total weight of the cosmetic composition, an oleogel may not be formed, and if it is included in an amount of more than 10 wt%, a stability problem of the formulation may occur.
[0037]
[0038] The term "polyol" of the present invention refers to a compound having multiple hydroxyl groups (-OH), and the polyol of the present invention may include a polyol having three or more hydroxyl groups, and more preferably, the polyol of the present invention may be at least one selected from the group consisting of glycerin, diglycerin, and sorbitol.
[0039] If the number of hydroxyl groups of the above polyol is less than 3, an oleogel of the formulation may not be formed, which may cause a problem in formulation stability.
[0040] The above polyol may be included in an amount of 0.1 to 20 wt% based on the total weight of the cosmetic composition.
[0041] When the above polyol is present in an amount of 0.1 wt% to 20 wt%, an oleogel can be stably formed and a stable formulation can be obtained.
[0042]
[0043] The term "oleogel" of the present invention refers to a semi-solid material composed of an oil phase and a surfactant phase, and the liquid oil phase is made to appear like a solid by using a specific surfactant phase, and the surfactant phase may bind the oil phase into a network structure to make it into a gel state.
[0044] The method for manufacturing the cosmetic composition of the present invention can form an oleogel by including a surfactant having an HLB of 15 or higher and a polyol having 3 or more hydroxyl groups. If the surfactant and polyol of the present invention are not used, an oleogel is not formed, and the oil component and the polyol are separated, which may cause a problem in the stability of the formulation.
[0045]
[0046] In the above surfactant, glycerin and surfactant may be included in a mixing ratio of 10:0.1 to 10:10.
[0047] If the ratio of the surfactant in the above mixing ratio is less than 0.1, the oleogel may not be formed, and if it exceeds 10, a stability problem of the formulation may occur.
[0048]
[0049] The term "oil component" of the present invention refers to an oil or fat component, which may exist in a state of being dispersed in water in the form of small particles in an emulsified cream formulation, and may be responsible for functions such as moisturizing, improving spreadability, and providing nutrition.
[0050] The above oil component may be at least one selected from the group consisting of low melting point butters, hydrocarbon oils, silicone oils, and ester oils.
[0051] Preferably, the oil component may be composed of low-melting-point butter, hydrocarbon oil, silicone oil, and ester oil.
[0052]
[0053] The above low-melting-point butter may be butter having a melting point of 20 to 40°C, and specifically may include shea butter, coconut butter or Borneo tallow seed butter.
[0054] The melting point may be the temperature at which a solid begins to melt into a liquid.
[0055] The hydrocarbon oil may contain squalane or hemisqualane.
[0056] The above silicone oil may contain dimethicone.
[0057] The above ester oil may include coco-caprylate / caprate.
[0058]
[0059] The above oil-based ingredient may be included in an amount of 0.1 to 20 wt% based on the total weight of the cosmetic composition.
[0060] If the above oil component is less than 0.1 wt% based on the total weight of the cosmetic composition, the O / D phase may not be formed, and if it exceeds 20 wt%, problems may arise with the stability of the formulation.
[0061]
[0062] The step of manufacturing the O / D gel phase including the above surfactant phase and oil phase component may be to manufacture the O / D gel phase by slowly adding the oil phase component to the D phase in which the surfactant phase is dispersed in the polyol while stirring at room temperature.
[0063] The step of preparing an O / W emulsion by adding an aqueous component to the O / D gel is as follows.
[0064] It may be possible to manufacture an O / W emulsion by slowly adding the aqueous component to the manufactured O / D gel while stirring at room temperature.
[0065]
[0066] Another aspect of the present invention for achieving the above object can provide a cosmetic composition manufactured by the method for manufacturing an emulsified cream formulation cosmetic composition of the present invention.
[0067] In a specific embodiment, a cosmetic composition manufactured by the manufacturing method of the present invention is manufactured by a low-energy process compared to an emulsified cream formulation cosmetic composition not manufactured by the manufacturing method of the present invention, and has a small average particle size, so that the stability of the formulation can be ensured even when stored for a long period of time.
[0068]
[0069] Each of the above-described components included in the cosmetic composition according to the present invention may be included in the cosmetic composition of the present invention within a range that preferably does not exceed the maximum usage amount stipulated in the “Cosmetics Safety and Technical Standards” established by the Chinese government.
[0070] The cosmetic composition of the present invention can be used according to a conventional method of use, and the number of times it is used can vary depending on the user's skin condition or preference.
[0071]
[0072] The advantages and features of the present invention, and the methods for achieving them, will become clearer with reference to the detailed embodiments and experimental examples described below. However, the present invention is not limited to the experimental examples and examples disclosed below, but may be implemented in various different forms. These examples are provided solely to ensure the complete disclosure of the present invention and to fully inform those skilled in the art of the invention of the scope of the invention.
[0073]
[0074] The cosmetic composition of the present invention is environmentally advantageous in terms of energy, and provides a cream formulation that embodies the properties, nutrition, and usability of a general O / W emulsified cream rather than a gel cream through a room temperature process.

[0080] Hereinafter, the present invention will be described in more detail through examples. These examples are intended to explain the present invention more specifically, and the scope of the present invention is not limited by these examples.
[0081]

[0097]
[0098] As shown in Table 2 above, stable compositions were produced in the compositions of Examples 1 to 5 containing 0.1 to 5 wt% of sucrose stearate, and it was confirmed that when sucrose stearate, such as in Comparative Example 1, was not included, the oil and polyol were separated, making it impossible to manufacture the composition.
[0099]
[0100] Examples 6 to 8 and Comparative Examples 2 to 6
[0101] In order to compare whether oligogels are formed depending on the type of polyol, Examples 6 to 8 and Comparative Examples 2 to 6 were prepared with the compositions shown in Tables 3 and 4 below.
[0102] Specifically, phase A was dispersed for 30 minutes, phase B was slowly added to phase A to prepare an oleogel, then phase C was added and stirred for 5 minutes, and then phase D was added and stirred for 5 minutes.

[0106]
[0107] As a result, as shown in Fig. 1, in Examples 6 to 8, an oleogel was formed with polyol on the outside and oil on the inside. On the other hand, in Comparative Examples 2 to 6 (ethanol: 1 hydroxyl group, dipropylene glycol, propanediol, butylene glycol, 2,3-butanediol: 2 hydroxyl groups), an oleogel was not formed, and a phenomenon of phase separation (layer separation) between the oil phase and the polyol and surfactant phases occurred.
[0108] Therefore, it was confirmed that polyols having three or more hydroxyl groups (-OH) (glycerin: three hydroxyl groups, diglycerin: four hydroxyl groups, sorbitol: six hydroxyl groups) are preferable in order to achieve the effect according to the present invention.
[0109]
[0110] Example 9 and Comparative Example 7
[0111] The composition containing sucrose stearate and glycerin was prepared with the same composition as in Table 5 below, but the manufacturing method was different as in Fig. 2 (Example 9) and Fig. 3 (Comparative Example 7), and Example 9 and Comparative Example 7 were prepared, and then the formulation stability and particle size differences were compared.
[0112] Specifically, Example 9 was manufactured according to the manufacturing method of the present invention, and Comparative Example 7 was manufactured according to the manufacturing method of a general high-temperature O / W emulsion.
[0113] More specifically, Example 9 was manufactured by dispersing phase A corresponding to phase D for 30 minutes, slowly adding phase B corresponding to the oily part of phase A while stirring, adding phase C corresponding to the water phase and stirring for 5 minutes, then adding D and stirring for another 5 minutes.
[0114] In Comparative Example 7, phase A and phase B, which correspond to the oil phase, were heated to 50 to 60°C and mixed and dissolved, then slowly added to phase C, which corresponds to the water phase and was heated, and stirred for 5 minutes. Then, D was added, stirred for 5 minutes, and cooled.

[0119] As shown in Table 6 above, as a result of the difference in manufacturing method for the same composition, it was confirmed that Example 9, compared to Comparative Example 7, ensured the stability of the formulation even when the storage period was long despite the manufacturing method being environmentally friendly (low-energy method).
[0120]
[0121] The particle sizes of Example 9 and Comparative Example 7 were measured and compared.
[0122] Specifically, Example 9 and Comparative Example 7 were diluted (10%) and the average particle size (D[4,3]) was measured using a particle size analyzer (mastersizer).
[0123] Example 9 Comparative Example 7 D[4,3](㎛) 1.173.95
[0124] As shown in Table 7 above, it was confirmed that the composition of Example 9 had a smaller particle size than Comparative Example 7, thereby realizing improved stability.
[0125] In summary of the results in Tables 6 and 7, it was confirmed that Example 9 manufactured by the manufacturing method of the present invention was able to reduce energy by shortening the manufacturing time by excluding the high temperature and cooling process, and to realize formulation stability.
[0126]
[0127] Example 10 and Comparative Example 8
[0128] Example 10 and Comparative Example 8 were manufactured with the compositions shown in Table 8 below by differentiating the HLB of the surfactant (emulsifier), and the formulation stability and particle size were compared.
[0129] Specifically, Example 10 (sucrose stearate, HLB 15) was manufactured using an emulsifier and glycerin having an HLB of 15 or higher, according to the composition in Table 8 below and the manufacturing method of the present invention.
[0130] More specifically, phase A of Table 8 was dispersed for 30 minutes, phase B was slowly added to phase A while stirring, phase C was added and stirred for 5 minutes, and then phase D was added and stirred for 5 minutes.
[0131] Comparative Example 8 (Polyglyceryl-10 Caprylate / Caprate. HLB 12-14, Polyglyceryl-4 Carprate. HLB 10-12) was manufactured using an emulsifier with an HLB of 14 or less and glycerin, using the composition in Table 8 and the manufacturing method of the present invention.

[0139]
[0140] The particle sizes of Example 10 and Comparative Example 8 were measured and compared.
[0141] Specifically, Example 10 and Comparative Example 8 were diluted (10%) and the average particle size (D[4,3]) was measured using a particle size analyzer (mastersizer).
