Description

Technology Field

[0001] The present invention relates to a cleansing balm composition for tube filling containing an oil-wax complex and a method for manufacturing the same. Background Technology

[0003] Jar-type cleansing balms, which address the inconvenience of dripping found in conventional cleansing oils, are highly preferred by consumers due to their superior usability and portability. However, currently commercialized jar-type cleansing balms have drawbacks, including hygienic limitations and the need for a spatula due to the scooping nature of the formulation. In this regard, there is a growing demand from consumers for the release of tube-type cleansing balms that are more hygienic and convenient while maintaining the same user experience. However, if the formulation of existing jar-type cleansing balms is simply filled into tube containers, problems such as blockage of the contents at the dispensing port or oil leakage may occur, compromising product stability and causing inconvenience to consumers.

[0004] These existing jar-type cleansing balm cosmetic compositions typically include solid components, liquid oil components, nonionic surfactants, and other nourishing components.

[0005] The above solid components include candelilla wax, ceresin, carnauba wax, paraffin, ozokerite, microcrystalline wax, synthetic wax, and polyethylene, which increase hardness to maintain the external shape of the cosmetic composition and improve the smoothness of the user experience.

[0006] The above liquid oil phase components include castor oil, jojoba oil, squalane, lanolin oil, lanolin derivatives, oils extracted from animals and plants, synthetic ester oils, and other oils.

[0007] The above nonionic surfactant components include Solves-30 tetraoleate, PEG-20 glyceryl triisostearate and PEG-10 isostearate, PEG-8 glyceryl isostearate, PEG-8 isostearate, sorbitan sesquioleate, polyglyceryl-3 polyricinoleate, polyglyceryl-6 dicaprate, polyglyceryl-10 oleate, etc.

[0008] In addition, other ingredients such as antioxidants, preservatives, fragrance components, and nutritional components are added to the cosmetic composition.

[0009] Previous studies have reported that oil-wax gel structures affect the physical properties and hardness of formulations, but there is no proper understanding of the stability issues when applying them to tubular products. Prior art literature

[0011] Korean Published Patent No. 10-2023-0045414 (Publication Date: April 4, 2023) The problem to be solved

[0012] The inventors have made diligent research efforts to solve the problems of outlet blockage and oil leakage that occur when jar-type cleansing balm compositions are filled into tubes, and to improve the stability of the formulation. As a result, by confirming that applying an oil-wax complex to existing cleansing balm compositions increases structural flexibility and reduces crystallinity to alleviate outlet blockage, and effectively captures oil through a three-dimensional network formed between hydrophobic silica particles to suppress oil leakage, the inventors have identified the possibility of using it as a tube-filled cleansing balm formulation, thereby completing the present invention.

[0013] Accordingly, the object of the present invention is to provide a cleansing balm composition for tube filling comprising an oil-wax complex composition.

[0014] Another objective of the present invention is to provide a method for preparing an oil-wax complex composition.

[0015] Other objects and advantages of the present invention will become more apparent from the following detailed description of the invention, claims, and drawings. means of solving the problem

[0017] The inventors have made diligent research efforts to solve the problems of dispensing port clogging and oil leakage that occur when jar-type cleansing balm compositions are filled into tubes, and to improve the stability of the formulation. As a result, by confirming that applying an oil-wax complex to existing cleansing balm compositions increases structural flexibility and reduces crystallinity to alleviate dispensing port clogging, and effectively captures oil through a three-dimensional network formed between hydrophobic silica particles to suppress oil leakage, the potential for use as a tube-filled cleansing balm formulation has been identified.

[0018] According to one aspect of the present invention, the present invention provides a cleansing balm composition for tube filling comprising an oil-wax complex composition, wherein the oil-wax complex composition comprises the following:

[0019] (a) styrene / butadiene mixed polymer, (b) hydrophobic silica, (c) solid component, (d) semi-solid emollient, and (e) liquid oil.

[0020] As used in this specification, the term “oil-wax complex” refers to a semi-solid or solid mixture formed by combining oil and wax, and performs the roles of viscosity control, usability improvement, moisturization, and formulation stabilization in cosmetics. Generally, it includes oil, wax, and a gelling agent comprising silica as a main ingredient.

[0021] As used in this specification, the term “Styrene / Butadiene mixed polymer” refers to a copolymer formed by the polymerization of styrene and butadiene, wherein styrene corresponds to a hard component that increases strength and glass transition temperature (Tg), and butadiene corresponds to a soft component that imparts elasticity and flexibility. The styrene / butadiene mixed polymer has a spring structure and exhibits excellent elasticity, which can structure the oil contained in the oil-wax composite and improve stability by minimizing deformation of the wax structure caused by pressure applied during tube discharge.

[0022] The above styrene / butadiene mixed polymer may include, but is not limited to, styrene / butadiene copolymers, hydrogenated styrene / butadiene copolymers, etc.

[0023] As used in this specification, the term “hydrophobic silica” refers to silica (SiO2) particles whose surfaces are chemically modified to have low affinity for water and high affinity for organic solvents or oils. While general hydrophilic silica is rich in Si-OH (silanol groups) on its surface and mixes well with water, hydrophobic silica has silanol groups substituted with organic silanes, which minimizes interaction with water and exhibits hydrophobicity. Hydrophobic silica can generally be produced through surface modification and, when applied to cosmetic formulations, can exhibit effects such as thickening, fluidity control, and improved usability.

[0024] The term “solid component” as used in this specification refers to a component that provides the hardness, viscosity, and physical stability of the formulation in an oil-wax complex, and includes solid waxes and synthetic materials. Generally, it is named an oil-wax complex because it includes solid waxes as solid components, but other materials other than wax may also be used as solid components. By using the solid component, the structural stability of the product is enhanced, and it plays an important role in determining the texture and feel of the formulation. Furthermore, the quality and usability of the product can be improved by controlling the melting point at a specific temperature or adjusting the hardness.

[0025] As used in this specification, the term “semi-solid emollient” refers to an ingredient that maintains a soft, creamy texture in an intermediate state between solid and liquid at room temperature (15-25°C) and provides skin softening and moisturizing functions. It forms a protective film on the skin surface to prevent moisture evaporation and provides flexibility, and is generally composed of high molecular weight aliphatic compounds. Due to its property of melting gently at skin temperature (32-37°C), it can help maintain an excellent user experience when applied to the skin, as is characteristic of cleansing balms, and can impart viscosity and improve the texture of creams, balms, ointments, etc.

[0026] As used in this specification, the term “liquid oil” refers to an oil component with hydrophobic properties that is insoluble in water, and signifies a major raw material constituting the oil phase of cosmetics or skincare products. Liquid oils are broadly classified into vegetable oils, triglyceride oils, mineral oils, silicone oils, synthetic ester oils, etc., and perform various roles such as moisturizing, skin protection, cleansing, and emulsion stabilization.

[0027] In one embodiment of the present invention, the hydrophobic silica of (b) is silica dimethyl sililate, silica dimethicone sililate, silica trimethyl sililate, and silica polymethylsilsesquioxane.

[0028] In a specific embodiment of the present invention, the hydrophobic silica of (b) is silica dimethyl silylate, but is not limited thereto.

[0029] The above silica dimethyl silylate can stabilize the formulation of a cleansing balm composition for tube filling while improving overall properties, and in one embodiment of the present invention, by including silica dimethyl silylate in the cleansing balm composition, a three-dimensional network is formed through hydrophobic interactions between silica particles with a large specific surface area, thereby effectively capturing oil and suppressing leakage phenomena.

Specific details for implementing the invention

[0068] The present invention will be described in more detail below through examples. These examples are intended solely to explain the invention more specifically, and it will be obvious to those skilled in the art that the scope of the invention is not limited by these examples according to the gist of the invention.

[0070] Examples

[0071] Throughout this specification, “%” used to indicate the concentration of a particular substance is (weight / weight) % for solid / solid, (weight / volume) % for solid / liquid, and (volume / volume) % for liquid / liquid, unless otherwise noted.

[0073] Preparation Example: Preparation of a cleansing balm composition containing an oil-wax complex

[0074] A cleansing balm composition comprising the oil-wax complex of the present invention can be prepared through the following method.

[0075] First, the styrene-butadiene mixed polymer, silica dimethyl silylate, solid component, semi-solid emollient, and liquid oil constituting the oil-wax complex were accurately weighed according to the composition. Then, the hydrophobic silica component was completely wetted into all components except the solid component at 65-85°C, and the mixture was stirred at a stirring speed of 500 rpm for 10 minutes to produce a uniform and clear solution. Subsequently, the solid component was added and homogeneously mixed once again at a stirring speed of 500 rpm for 10 minutes to prepare the oil-wax complex.

[0076] In addition, the remaining components constituting the cleansing balm composition were further added to the oil-wax complex prepared by the above-described method, homogeneously stirred at 500 rpm for 15 minutes at a temperature of 65-85℃, and then cooled at room temperature to obtain a cleansing balm composition comprising the oil-wax complex in the state of a milky white solid balm.

[0077] The above stirring or mixing can be performed using a mixer such as an Agimixer. In addition, the time and speed (rpm) of the stirring or mixing may vary depending on the ambient temperature of the workplace and the capacity of the mixer, and such stirring or mixing can be appropriately performed either empirically by those skilled in the art or according to the instructions of the mixer manufacturer. Specifically, in the present invention, the stirring process was performed at 500 rpm for 10 minutes.

[0078] The composition of the cleansing balm used in Experimental Examples 1 to 5 to verify tube filling suitability and cleaning power is shown in Table 1 below.

[0079] OleoFlex EG 200 (Manufacturer: Applechem) was used as the thermo-reversible elastomeric gel in Table 1 below, and the composition is as follows: Caprylic / Capric Triglyceride 37%, Helianthus Annuus Seed Oil 45%, Styrene / Butadiene Copolymer 18%.

[0085] Experimental Example 1: Analysis of Physical Properties According to Oil-Wax Composite Composition

[0086] To analyze the differences in physical properties according to the oil-wax complex composition of the cleansing balm, formulation stability and hardness were measured. Each cleansing balm composition prepared according to the manufacturing method of the above-mentioned preparation example was filled into a PP material tube. The appearance of each composition filled into the tube is shown in Fig. 1.

[0088] Experimental Example 1.1: Analysis of Formulation Stability According to Oil-Wax Complex Composition

[0089] First, we intended to analyze the formulation stability according to the oil-wax complex composition. To this end, cleansing balms filled in PP material were stored in an incubator set at 25°C, and 0.5g of the sample was dispensed at weekly intervals for 3 months, starting 1 week after the manufacturing date, to evaluate the phenomena of nozzle blockage and oil leakage by visual observation. The results are shown in Table 3 below.

[0091] * O: Stable; △: Oil dripping; X: Oil leakage; ■: Discharge port blockage

[0093] According to the above results, no oil leakage occurred under TCB-K conditions even during long-term storage, and no outlet blockage was observed, resolving the issues seen in existing cleansing balms. This implies that it possesses the most stable formulation compared to other conditions.

[0095] Experimental Example 1.2: Hardness Analysis According to Oil-Wax Composite Composition

[0096] Next, the change in hardness according to the oil-wax complex composition of the cleansing balm was analyzed using a rheometer (SUN RHEO METER CR-100), and the results are shown in Figure 2.

[0097] Specifically, for measurement, the sample was placed on the measuring table, an adapter was installed on the surface of the sample, and three repeated measurements were performed, with the average value used as the hardness. After manufacturing, approximately 100 g of the tube-type cleansing balm was divided into 100 mL sample containers and aged at 25°C for 24 hours before measurement.

[0098] The results were analyzed based on three major scales, and according to Figure 1, it was confirmed that as the content of thermo-reversible elastomeric gel in the oil-wax complex increased, the hardness decreased (Figure 1a), as the content of synthetic wax decreased, the hardness decreased (Figure 1b), and as the content of hydrophobic silica increased, the hardness decreased (Figure 1c). Therefore, it was confirmed that the TCB-K sample, which contains the lowest proportion of synthetic wax and the highest proportions of thermo-reversible gel and hydrophobic silica within the composition range, had the lowest hardness.

[0100] Experimental Example 2: Analysis of Thermal Properties of Oil-Wax Composites by Composition

[0101] Next, Differential Scanning Calorimetry (DSC) was used to analyze the thermal properties according to changes in the composition of the oil-wax composite.

[0102] Differential Scanning Calorimetry (DSC) is an instrument used to measure heat exchange when observing the phase transition behavior of polymeric materials. It measures the difference in heat flux between a sample and an inert reference material as a function of time and temperature while heating and cooling the sample and the reference material at the same rate. When a sample absorbs energy, the enthalpy change is endothermic, while when it releases energy, it is exothermic. DSC can provide various information regarding enthalpy changes, as well as thermal properties such as the glass transition temperature (Tg), crystallization temperature (Tc), and melting temperature (Tm).

[0103] In the present invention, DSC analysis was used to analyze the phase change behavior of the oil-wax complex, which is the core ingredient of the tube-type cleansing balm, and data such as the crystallization temperature (Tc), melting temperature (Tm), heat of fusion, and heat of crystallization were collected through a process of first heating, first cooling, and second heating.

[0104] The composition of the oil-wax complex used in the DSC is shown in Table 4 below, and the results of the analysis are shown in Table 5 and Figure 3.

[0109] According to the analysis results, the TCB-K composition oil-wax composite consisting of appropriate proportions of synthetic wax, hydrophobic silica, and thermoelastic gel was found to have lower △H (J / g), Tm (°C), and Onset (°C) compared to other conditions.

[0110] These results indicate that the Wax-o (TCB-K ratio) sample has the flexibility to induce material changes with relatively little energy, which means that tube ejection is possible with little force. In addition, the change in the peak curve of Wax-o (TCB-K ratio) compared to Wax-K (control group) indicates that the degree of crystallinity has decreased and that the formulation has low hardness, which is consistent with the result in previous Experimental Example 1.2 where TCB-K had the lowest hardness.

[0111] Therefore, the increased flexibility exhibited in this Wax-o (TCB-K ratio) allows the formulation to be easily dispensed from the tube with less force, thereby enhancing the usability and suitability of the tube-type cleansing balm.

[0113] Experimental Example 3: Microstructure Analysis According to Oil-Wax Composite Composition

[0114] To observe the microstructure of cleansing balm compositions according to oil-wax complex compositions, the surface of each composition was imaged using Field Emission Scanning Electron Microscopy (FE-SEM). Through this, the degree of crystallinity, surface roughness, and microstructure were analyzed, and the effect of the oil-wax complex composition on the surface roughness of the composition was determined. The results are shown in Figure 4 and Table 6 below.

[0115] Rq Ra Rv Rp Rt SA TCB-A (control group) 43.994 32.7601 -42.2088 159.0070 201.2158 902.8366 TCB-K 32.0498 22.7720 -34.3276 148.0389 182.3664 1032.0670

[0117] The indicators in Table 6 are all key indicators used to evaluate surface roughness and shape characteristics in FE-SEM analysis.

[0118] The greater the change in surface height, the higher the Rq and Ra values ​​become. Additionally, since Rv represents the depth of the deepest valley on the surface, Rp represents the height of the highest peak, and Rt represents the total height difference between the highest peak and the deepest valley, a higher absolute value of these indicators indicates higher roughness. SA is an indicator representing the actual surface area.

[0119] According to the analysis results, the TCB-K composition with the lowest hardness showed lower Rq and Ra values ​​compared to the control group (TCB-A), and also lower absolute values ​​of Rv, Rp, and Rt; these results indicate that the surface roughness of TCB-K was reduced compared to the control group.

[0120] In the control group, it is presumed that oil leakage occurs as the wax arrangement becomes disrupted, the surface roughens, and wide voids form between crystals due to the applied pressure during discharge, while discharge port clogging is judged to have occurred due to the high degree of crystallization. On the other hand, TCB-K is considered to provide superior stability as discharge clogging and oil leakage are improved through the control of surface roughness and degree of crystallization.

[0122] Experimental Example 4: Evaluation of the degree of oil leakage of a cleansing balm containing an oil-wax complex

[0123] In order to confirm whether the cleansing balm composition under the conditions selected through the analysis experiment in the above experimental example also shows an improvement effect in terms of oil leakage, the degree of oil leakage over time was measured using oil blotting paper, and the results are shown in Fig. 5.

[0124] According to Figure 5, it can be seen that the TCB-K cleansing balm composition shows a noticeable reduction in oil leakage on oil blotting paper at all times compared to the control group (TCB-A) cleansing balm composition. This result can be attributed to the effect of effectively capturing oil by forming a three-dimensional network through hydrophobic interactions between silica particles with a large specific surface area. Consequently, this implies that when the cleansing balm composition of the present invention is filled into a tube, the oil leakage phenomenon can be mitigated compared to when a conventional cleansing balm composition is filled into a tube.

[0126] Experimental Example 5: Measurement of cleansing power of a cleansing balm composition containing an oil-wax complex

[0127] The cleansing power of the oil-wax complex-containing cleansing balm composition of the present invention was to be compared with TCB-A (control group), which corresponds to a conventional jar-type cleansing balm composition.

[0128] Specifically, liquid foundation was applied to black artificial leather, and then a certain amount of cleansing balm composition was applied to cleanse it. The cleansing power was measured by comparing the number of color cosmetic pixels in the image before and after cleansing, and the results are shown in Figure 6.

[0129] According to Figure 6, when using TCB-K, an average pixel count reduction rate of 93.85% was observed, and TCB-A showed an average reduction rate of 86.01%, indicating that TCB-K has superior cleaning power for liquid foundation.

[0130] Therefore, it is determined that the cleansing balm containing the oil-wax complex of the present invention not only solves the problems of outlet blockage and oil leakage that frequently occur when using conventional compositions during tube filling by increasing formulation stability, but also exhibits superior effects in terms of cleaning power.
