Description

Technical Field

[0001] The invention belongs to the technical field of cosmetics, and specifically relates to an emulsified composition and a preparation method and application thereof. Background Art

[0002] Emulsification is the process of evenly dispersing a liquid in another immiscible liquid in the form of extremely small droplets through the establishment of an interface. The common emulsification method is to heat the external phase, internal phase and surfactant (emulsifier) ​​to a certain temperature, and under high-speed stirring, make the two phases form a relatively stable and uniform emulsion, and then keep the temperature and cool it down. In the emulsification process, the emulsifier plays a vital role. It can significantly reduce the surface tension between the two phases, change the interface state of the system, and form a monomolecular interface film, thereby stabilizing the system. The appearance of the emulsion is generally a milky white opaque liquid. When the diameter of the dispersed phase droplet of the emulsion is less than 0.1μm, the appearance is translucent or transparent, which is called a microemulsion. Most cream products in cosmetics are emulsified systems. Emulsification can combine some immiscible components. The emulsion can make the product have both the physical properties and functional properties of the two phases. The formation of the emulsion is more conducive to human absorption.

[0003] CN102415955A discloses an emulsified composition, which is used to prepare a cosmetic product using a D-phase emulsification gel composition, thereby improving the emulsification stability and reducing the amount of a thickener. The emulsified composition contains methoxy polyethylene 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 stirring mixer to prepare an oil-in-water emulsion composition. Even if diluted, the dispersion state of the fine emulsified particles is stable, and an oil-in-water emulsion composition with less skin irritation is prepared. In 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, an oily component is added to prepare an O / D phase composition in which the pH of a 10 mass % aqueous solution is adjusted to 5.0 or less, and a stirring mixer such as a homogenizer is used to prepare an oil-in-water emulsion composition having a particle size (median particle size) less than 1.0 μm.

[0005] However, during the emulsification process of the above composition, the temperatures of the oil and water phases must be controlled between 70°C and 85°C. If there are raw materials with a higher melting point in the oil phase, a higher temperature is required. After emulsification, it is also necessary to keep warm 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] In view of the deficiencies of the prior art, the present invention provides an emulsified composition and a preparation method and application thereof, wherein the emulsified composition can reduce the heating and cooling processes during the emulsification process to reduce energy consumption, selectively apply heat energy to processes requiring energy, and can meet the requirements of low energy consumption, simple process, and efficient production. Moreover, after the emulsified composition of the present invention is applied to cosmetics, it can also solve the problems of large droplet diameter and low viscosity of the emulsion, so that the final product has the characteristics of high appearance transparency, moderate viscosity, small emulsified particle size, and good skin feel.

[0117] Test Example 2

[0118] Cleansing test for makeup (liquid foundation, lipstick, eyeliner):

[0119] Test subjects: 102 volunteers were divided into 17 groups, with 6 people in each group. The 17 groups of volunteers used the makeup removal gel prepared in Application Examples 1-14 and Comparative Application Examples 1-3 for cleaning.

[0120] The test method is: apply liquid foundation, lipstick, and eyeliner on the dry and clean inner side of the subject's arm.

Use a dermatoscope to photograph the test area before and after makeup application and after makeup removal, use IPP software to analyze the pictures, and obtain the lightness L, red / green value a, and blue / yellow value b of each area.

[0125] As can be seen from Application Examples 4-7, the formula of sucrose fatty acid ester also has a great influence on the makeup removal effect of the makeup removal gel;

[0126] As can be seen from Application Examples 8-9, the lack of any one of the components, C9-19 alkane or butanediol dicaprylate / dicaprate, will lead to a significant decrease in the makeup removal power of the system;

[0128] It can be seen from comparative application examples 1-3 that the absence of any component in the emulsified composition cannot form a makeup removal gel, thereby affecting the makeup removal effect.

[0129] Test Example 3 Consumer Sensory Effect Evaluation

[0130] The test subjects and test example 2 are the same group of volunteers. Test method: The test subjects used the makeup removal gel prepared in application examples 1-14 and comparative application examples 1-3 respectively. The test subjects used daily skin care products normally during the day, took an appropriate amount of gel on their hands every night, dried their hands and faces, massaged in circles on the face to dissolve the makeup, massaged with a small amount of water to emulsify, and then rinsed with water. Then the mildness, skin feel, cleaning feel and makeup removal power of the product were scored, and the scores were averaged. The evaluation results are shown in the table below, using a 5-point system: 4.5 points and above, indicating very good, very satisfied; 4-4.5 points are good; 3-4 points are moderately acceptable; 3 points or less are not good, unacceptable. The score of each group is the average of 10 people, and the results are shown in Table 5.

[0131] Table 5

[0132]

[0133] As shown in Table 5, the human body trial results of Application Examples 1-3 show that the makeup removal gel prepared by using the emulsified composition of the present invention has a good user experience.

[0135] As can be seen from 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] From Application Examples 10-11, we can see that the combination of auxiliary surfactants laureth-3 and polysorbate-20 can bring better cleaning and skin feel, but excessive addition of laureth-3 may affect mildness;

[0137] It can be seen from Application Examples 12-14 that 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 removal gel, thus affecting the experience.

[0139] Test Example 4 Safety Evaluation:

[0140] The specific method is: 35 males / females aged 18-55 years old with no history of allergies are selected, and each subject is tested with the products prepared in Application Examples 1-14. A qualified patch tester is selected, and the sample is added to the patch tester by the closed patch test method, about 0.020ml-0.025ml, and the sample is applied to the curved side of the forearm of the subject with a special adhesive tape. After 24 hours, the test substance is removed, and the skin reaction is observed 30 minutes, 24 hours, and 48 hours after removal, and the results are recorded according to the skin reaction grading standard (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:
