Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of cosmetics, and in particular relates to an emulsified composition, a preparation method and an application thereof. Background Art
[0002] Emulsification is the process of uniformly dispersing one liquid in the form of extremely tiny droplets within another immiscible liquid through the creation of an interface. A common emulsification method involves heating the external phase, internal phase, and surfactant (emulsifier) to a certain temperature and, under high-speed stirring, allowing the two phases to form a relatively stable and uniform emulsion. The mixture is then insulated and cooled. Emulsifiers play a crucial role in the emulsification process, significantly reducing the surface tension between the two phases, altering the interfacial state of the system, and forming a monomolecular interfacial film, thereby stabilizing the system. Emulsions typically appear as milky white, opaque liquids. When the diameter of the dispersed phase droplets in an emulsion is less than 0.1 μm, the liquid becomes translucent or transparent, and is called a microemulsion. Creams and creams in cosmetics are often emulsified systems. Emulsification can combine immiscible components, allowing products to combine the physical properties and efficacy of both phases. The formation of emulsions is also more conducive to absorption by the human body.
[0003] CN102415955A discloses an emulsified composition. This invention produces an emulsified composition with a small emulsified particle size, improving emulsion stability and reducing the amount of thickeners used in cosmetics prepared using a D-phase emulsification method gel composition. The emulsified composition contains methoxypolyethylene glycol polymethacrylate, polyglycerol fatty acid ester, glycerin, and an oily component.
[0004] CN117618258A discloses an O / D phase composition and an oil-in-water emulsion composition. The O / D phase composition can be prepared using a general-purpose stirring mixer to form an oil-in-water emulsion composition. Even when diluted, the dispersion state of the fine emulsified particles is stable, resulting in an oil-in-water emulsion composition that is less irritating to the skin. An oily component is added to a surfactant component (cleanser) phase component obtained by dissolving one or more selected from glycyrrhizic acid and its salts in a trivalent or higher polyol to form an O / D phase composition having a pH of 5.0 or less in a 10% by mass aqueous solution. The O / D phase composition is then formed using a stirring mixer such as a homogenizer to form an oil-in-water emulsion composition having a particle size (median particle size) of less than 1.0 μm.
[0005] However, during the emulsification process of the above-mentioned composition, the temperatures of both the oil and water phases must be controlled between 70°C and 85°C. If there are raw materials with higher melting points in the oil phase, a higher temperature is required. After emulsification, it is also necessary to keep the temperature and stir, which consumes a lot of energy. Finally, the emulsion needs to be cooled, and cooling water must be used. This process wastes a lot of energy. Therefore, it is urgent to provide a product with better emulsification effect and lower energy consumption in the emulsification process to meet application needs. Summary of the Invention
[0006] To address the shortcomings of the prior art, the present invention provides an emulsified composition, its preparation method, and its application. This emulsified composition reduces energy consumption by eliminating heating and cooling steps during the emulsification process, selectively applying heat energy to energy-requiring processes. This approach meets the requirements of low energy consumption, simplified processes, and efficient production. Furthermore, when applied to cosmetics, the emulsified composition of the present invention can address the issues of large emulsion droplet diameter and low viscosity, resulting in a product with high transparency, moderate viscosity, small emulsified particle size, and a pleasant skin feel.

[0054] (2) The emulsified particle size of the emulsified composition of the present invention is smaller than that of ordinary emulsions after being used in cosmetics, and the particle size distribution range is narrower, creating a better skin feel and having higher kinetic stability. The smaller particle size helps to effectively deliver active ingredients to the skin, and can be used as a potential carrier of cosmetic ingredients, so that the active ingredients can be optimally dispersed in specific skin layers, with better efficacy. In addition, the smaller particle size can quickly penetrate deep into the skin and pores, better washing away makeup and dirt.
[0055] (3) The makeup remover gel provided by the present invention is mixed with components such as polyols and oils through a specific emulsifying composition, which can improve the emulsification effect of the product. A small amount of water can form a bicontinuous phase structure, thereby making the makeup remover more effective. DETAILED DESCRIPTION

[0129] Test Example 3 Consumer Sensory Effect Evaluation
[0130] The test subjects were the same volunteers as in Test Example 2. Test Method: The test subjects used the makeup remover gels prepared in Application Examples 1-14 and Comparative Application Examples 1-3, respectively. The test subjects used their daily skincare products normally during the day. Every night, they applied an appropriate amount of gel to their hands, dried their hands and face, and massaged the gel in circular motions to dissolve the makeup. They then massaged the gel with a small amount of water to emulsify the makeup, and then rinsed it off with water. The products were then rated for mildness, skin feel, cleansing properties, and makeup removal. The average score was taken, and the evaluation results are shown in the table below. The 5-point scale is as follows: 4.5 points and above indicate excellent (very satisfactory); 4-4.5 points indicate good; 3-4 points indicate acceptable; and 3 points or less indicate poor (unacceptable). The scores for each group are the average of 10 participants, as shown in Table 5.

[0134] As can be seen from Application Examples 4-7, the formula of sucrose fatty acid ester also has a significant impact on the experience of makeup remover gel;
[0135] As shown in Application Examples 8-9, C9-19 alkanes and butylene glycol dicaprylate / dicaprate can improve the makeup removal ability and skin feel of the system;
[0136] As shown in Application Examples 10-11, the combination of auxiliary surfactants laureth-3 and polysorbate-20 can provide better cleaning and skin feel, but excessive addition of laureth-3 may affect mildness.
[0137] As shown in Application Examples 12-14, the addition of skin conditioners can increase the mildness and skin feel of the system, and the hydrolyzed ginsenosides and Centella asiatica extract have a synergistic effect;
[0138] It can be seen from comparative application examples 1-3 that the absence of any component in the emulsified composition cannot form a makeup remover gel, thereby affecting the experience.

[0140] The specific method is as follows: 35 male and female subjects aged 18-55 years with no history of allergies were selected. Each subject was tested with the products prepared in Examples 1-14. Using a qualified patch tester, approximately 0.020ml to 0.025ml of the sample was added to the patch tester. The patch was then applied to the subject's flexed forearm using specialized adhesive tape. After 24 hours, the test substance was removed. Skin reactions were observed 30 minutes, 24 hours, and 48 hours after removal. Results were recorded according to the skin reaction grading standards (Table 6) in the "Safety Technical Specifications for Cosmetics" (2015 edition).
[0141] The grading standards for adverse skin reactions are shown in Table 6:
[0142] Table 6
[0143]
[0144] The results are shown in Table 7:
[0145] Table 7
[0146]
[0147] The data in Table 7 show that no adverse skin reactions were observed 30 minutes, 24 hours, and 48 hours after the spot tester was removed. This indicates that the makeup remover gel of the present invention has no adverse reactions on the human body and is highly safe.
