Description

Technical Field

[0001] This application relates to the technical field of daily-use cosmetics, and particularly to a soft-focus moisturizing makeup setting spray product and its preparation method. Background Art

[0002] Common makeup setting products on the current market mainly include types such as powder puffs, loose powders, and makeup setting sprays. Among them, powder puffs and loose powders have a dry texture, and using them after makeup is not conducive to skin moisturization and is prone to caking problems, which is particularly unfriendly to consumers with dry skin types. Although makeup setting sprays can be used before or after makeup and have both moisturizing and makeup setting functions, existing products generally have two defects: one is that the makeup effect is too shiny and difficult to meet the needs of some consumers for a natural makeup look; the other is that it is easy to stick to the hands after forming a film and has insufficient waterproofness. Summary of the Invention

[0003] In view of these problems, the present invention provides a new type of soft-focus moisturizing makeup setting spray, which realizes the dual effects of oil control and moisturization by adding soft-focus oil-control powder, can not only maintain the long-lasting effect of makeup but also present a high-class soft mist makeup effect.

[0004] In the first aspect, a soft-focus moisturizing makeup setting spray product provided by this application adopts the following technical solution: A soft-focus moisturizing makeup setting spray product, the components of its preparation raw materials, calculated by weight percentage, include the following components: Water 80 - 95%, moisturizer 1.0 - 5.0%, film-forming aid 0.5 - 10.0%, functional powder 1.0 - 10.0%; The functional powder is at least one of silica, vinyl polydimethylsiloxane / polymethylsiloxane sesquisiloxane cross-linked polymer, and polydimethylsiloxane / vinyl polydimethylsiloxane cross-linked polymer.

[0005] By adopting the above technical solution, the technical effects of having both oil control and moisturization dual effects, maintaining the long-lasting effect of makeup, and presenting a high-class soft mist makeup effect are achieved. This is because the spray uses a high proportion of water as the basic solvent to ensure a certain degree of freshness, adds a moisturizer to meet the moisturization requirements, and avoids caking problems for dry skin types; At the same time, oil control and soft focus are achieved by adding specific functional powders, and the characteristics of these powder components help to form a uniform and delicate film, making the makeup effect present a natural soft focus, overcoming the defect that the makeup effect of existing makeup setting sprays is too shiny. The addition of the film-forming aid can form a stable network structure on the skin and a film that is not easy to stick to the hands, enhancing the waterproofness and solving the problem of being easy to stick to the hands and having insufficient waterproofness after forming a film.

[0006] Furthermore, the functional powder is coated with a hydrophilic reagent, and the hydrophilic reagent used includes at least one of PEG-7 glyceryl cocoate, methylsilanol tri-PEG-8 glyceryl cocoate, polysorbate-20, PPG-13-decyltetradeceth-24, and PPG-1-PEG-9 lauryl glycol ether.

[0007] Furthermore, the soft-focus moisturizing and makeup setting spray product further includes 0.01-0.1% of essence and 0.015-0.4% of solubilizer.

[0008] In some possible embodiments, it further includes preservatives and pH regulators. The preservatives are selected from at least two of 1,2-hexanediol, ethylhexylglycerin, caprylyl glycol, p-hydroxyacetophenone, and phenoxyethanol; the pH regulators are selected from at least one of sodium hydroxide, triethanolamine, aminomethylpropanol, and arginine.

[0009] Furthermore, the solubilizer is selected from at least one of PEG-40 hydrogenated castor oil, polysorbate-20, PPG-26-butanol polyether-26, and ceteareth-7; and the dosage ratio of the solubilizer to the essence is (1.5-4.0):1 by mass ratio.

[0010] Furthermore, the moisturizer is selected from at least one of butanediol, propylene glycol, glycerin, and pentylene glycol.

[0011] Furthermore, the film-forming agent is selected from at least one of polyvinylpyrrolidone, VP / acrylic acid (ester) / lauryl methacrylate copolymer, and VP / VA copolymer.

[0012] By adopting the above technical solutions, the functional powder is coated with a hydrophilic reagent, which improves its dispersibility and skin-friendly property in the formulation, helps to form a more uniform and delicate makeup film, and at the same time enhances the moisturizing and oil control effects; adding essence gives the product a pleasant aroma and improves the use experience; the addition of solubilizer increases the solubility of oil-soluble components such as essence in the formulation and ensures the stability of the product texture; the combined use of preservatives effectively extends the shelf life of the product and ensures safety; the pH regulator precisely controls the acidity and alkalinity of the product to ensure a match with the skin pH value and reduce irritation; the specific dosage ratio of solubilizer to essence ensures the full dissolution of essence and the stability of the product; the selection of moisturizer enhances the moisturizing ability of the product and avoids caking of dry skin; the use of a specific film-forming agent ensures the durability and waterproofness of the makeup, while taking into account the presentation of a soft-focus makeup effect.

[0013] In a second aspect, the present application provides a preparation method of a soft-focus moisturizing and makeup setting spray product, which is characterized by including the following steps: S1. Mix water and a moisturizer in a reactor, add part of a pH regulator and a preservative, stir and mix evenly at a rate of 100 - 600 rpm at 25 - 35°C, then continue to add a film-forming aid and stir at a rate of 200 - 600 rpm until completely dissolved without particles; S2. Pre-mix the fragrance and a solubilizer and add them to the reactor, disperse evenly at a rate of 100 - 600 rpm, then finally add the functional powder, continue to stir until evenly dispersed, add the remaining pH regulator, and adjust the pH value of the mixed system to 4.0 - 8.5 to obtain the product.

[0014] Furthermore, the pH regulator is at least one of sodium hydroxide, triethanolamine, aminomethylpropanol, and arginine.

[0015] By adopting the above technical solutions, the full dissolution and fusion of each component are achieved, the texture of the product is delicate and stable, the pH value is accurately adapted to the skin, and the functional components can effectively play their roles. Finally, a soft-focus moisturizing makeup setting spray with good use effects and stability is prepared.

[0016] In summary, the present application has the following beneficial effects: 1. By adding a functional powder coated with a hydrophilic reagent, the present application achieves the dual effects of oil control and moisturization, maintains the long-lasting degree of makeup, and presents an advanced soft matte makeup effect, overcoming the defects of the existing makeup setting spray with a shiny makeup effect, being sticky after film formation, and insufficient waterproofness; at the same time, components such as a moisturizer, a film-forming agent, a fragrance, a solubilizer, a preservative, and a pH regulator are reasonably matched to ensure the stable texture, pleasant smell, high safety of the product, and accurate matching with the skin pH value to reduce irritation; 2. The present application adopts scientific preparation methods such as step-by-step mixing, accurately controlling the stirring rate and temperature, adding and adjusting the pH value in stages, etc., to fully dissolve and fuse each component, and finally prepares a soft-focus moisturizing makeup setting spray with good use effects and stability.

[0028] For the spray products prepared in the above examples and comparative examples, they were used as test specimens, and physical property tests were carried out with reference to the multi-layer type test standard of GB / T2660-2004 lotion; Appearance requirements: same as the standard sample; Fragrance: conform to the specified fragrance type; pH: 4.0 - 8.5; Heat resistance: Keep at (40 ± 1) °C for 24 h, and there is no obvious difference in properties after returning to room temperature compared with before the test; Cold resistance: Keep at (-5 ± 1) °C for 24 h, and there is no obvious difference in properties after returning to room temperature compared with before the test; The test results are shown in the following table.

[0029] Verification test of makeup effect brightness and natural makeup look: Recruit 150 volunteers with oily or combination skin, aged between 25 - 35 years old and of different genders, and then divide them into 5 groups evenly, and measure the glossiness value on the skin surface using a skin glossiness tester; The specific test conditions are as follows: After the subjects clean their faces, they complete the base makeup (foundation, concealer, etc.) according to the daily skin care and makeup procedures, and sit still for 30 minutes in a test environment with constant temperature and humidity (temperature 22 ± 2 °C, humidity 50 ± 5%) to make the skin state stable; then the subjects evenly spray the makeup setting spray sample on the face according to the product instruction manual, and wait for 5 minutes to allow the makeup setting spray to fully form a film.

[0030] Using a skin glossiness tester, measure the glossiness values 3 times each on the forehead, nose wings, cheeks, chin and other parts of the subjects' faces, and take the average value as the glossiness data for that part.

[0031] Record the glossiness data of all parts of all subjects, and conduct statistical analysis to score the naturalness and brightness of the makeup effect (1 - 10 points, 1 point means very unnatural / not bright, 10 points means very natural / very bright).

[0032] Stickiness test after film formation: Gently press the finger on different parts of the face (forehead, nose wings, cheeks, chin), keep it for 3 seconds and then move it away. Use a stickiness tester to measure the sticky substances remaining on the finger and record the stickiness value.

[0033] Record the sticky feeling when pressing the finger on the face (no stickiness, slightly sticky, obviously sticky, severely sticky), and conduct scoring (1 - 4 points, 1 point means no stickiness, 4 points means severely sticky).

[0034] Waterproof test: Use a spray device to evenly spray deionized water on the subjects' faces with a certain pressure and flow rate to simulate a rain environment, and continuously spray for 30 seconds. After spraying, let the subjects gently shake their heads to make the excess water drip naturally. Observe the changes in the facial makeup, such as whether there is makeup removal, mottling, smudging, etc., and use a tissue to gently press the face to observe the makeup removal marks on the tissue.

[0035] Score according to the degree of makeup removal (1 - 5 points, 1 point means no makeup removal, 5 points means severe makeup removal).

[0036] The test results are shown in the following table.

[0037] According to the data in the above table, it can be seen that the setting spray products prepared in Examples 1 to 8 of this application all show good performance in key performance indicators such as makeup effect, stickiness after film formation, and waterproofness.

[0038] In the selection of moisturizers, the combination of butylene glycol and glycerol performs excellently, which can effectively improve the moisturizing performance of the product and make the makeup more fitting and natural. In terms of film formers, the combined use of polyvinylpyrrolidone, VP / acrylates / lauryl methacrylate copolymer and VP / VA copolymer significantly enhances the stability and durability of film formation, and at the same time improves the stickiness problem after film formation; Further research found that when the functional powder is composed of a vinyl polydimethylsiloxane / polymethylsiloxane sesquisiloxane cross-linked polymer and a polydimethylsiloxane / vinyl polydimethylsiloxane cross-linked polymer in a mass ratio of 2:1, all the properties of the product are significantly improved. This specific powder combination not only enhances the soft mist effect of the makeup effect but also improves the water resistance and stability of the film formation.

[0039] In addition, from the data of the comparative examples, we can observe that only when the functional powder is coated with two hydrophilic reagents, namely methylsilanetriol tri-PEG-8 glyceryl cocoate and PPG-1-PEG-9 lauryl glycol ether, does the setting spray product show significant advantages in terms of makeup effect, sticky feeling, and water resistance. This indicates that a specific combination of hydrophilic reagents is crucial for improving the product performance.

[0040] Among all the embodiments, the setting spray product prepared in Example 5 of this application performs the best and can be used as the most preferred embodiment. The spray state can be referred to in the appendix Figure 1 , this product not only has excellent performance but also can present an advanced soft mist makeup effect. It is non-sticky after film formation and has good water resistance, fully meeting the consumers' demand for a natural and advanced makeup look.

[0041] The above are all modifications or solutions that are obvious technical inspirations made by those skilled in the art after reading this specification according to their needs without creative contributions, but as long as they are within the scope of the claims of this application, they should be protected by the patent law.
