Description

Technology Field

[0001] The present invention relates to a water-soluble liquid cosmetic composition for hair and a method for manufacturing the same. More specifically, the invention relates to a water-soluble liquid cosmetic composition for hair and a method for manufacturing the same, which has excellent drying speed and maintains durability without causing burrs due to film formation, and has minimal transfer, even though it does not contain a styrene-based film-forming agent or ethanol. Background Technology

[0002] Women's instinct to pursue beauty is nothing new, but recently, there has been a growing trend of interest in body shape management, beauty treatments, and cosmetics aimed at making themselves look even more attractive.

[0003] And as not only women but also men are becoming interested in cosmetics for skin care, the cosmetics market continues to expand, and various types of cosmetics are being released into the market.

[0004] Generally, cosmetics can be broadly classified into basic cosmetics, makeup bases, and color cosmetics, and are manufactured as solid, liquid, or gel-type cosmetics, and various cosmetic containers are used to store them.

[0005] Recently, functional cosmetics capable of performing various functions such as moisturizing, whitening, wrinkle improvement, UV protection, acne relief, atopic dermatitis relief, anti-inflammatory effects, and keratolytic effects are also being widely consumed.

[0006] Meanwhile, while hair loss and gray hair were previously considered primarily a natural process of aging, in modern society they are occurring widely across all age groups due to various external factors.

[0007] In particular, various causes such as unbalanced dietary habits, excessive drinking and smoking, lack of sleep, overwork, stress, environmental pollution, medication use, childbirth, menopausal disorders, and hormonal imbalances are exacerbating these symptoms. This hair loss and graying affect an individual's appearance and can lead to social and psychological problems, such as a decline in self-confidence.

[0008] Accordingly, there is an increasing demand for cosmetics that can immediately solve these problems, and various hair cover products already exist in the market.

[0009] However, existing products such as hair dye powders had problems such as excessive dusting when applied, low durability, easy residue after use, and leakage or clumping of the contents when carried.

[0010] Furthermore, many hair products currently in use contain aromatic hydrocarbons such as styrene or ethanol. While these ingredients may provide a rapid drying effect and improve user experience, styrene is not only classified as a potential carcinogen but can also irritate the respiratory system and skin, whereas ethanol can dry out the skin and cause long-term skin problems.

[0011] In addition, in the case of styrene-based or ethanol-containing acrylate-based film-forming agents, burrs form after drying, resulting in reduced durability and an unsightly appearance.

[0012] Therefore, there is a growing need for a water-soluble liquid cosmetic composition for hair that does not contain styrene-based film-forming agents or ethanol, yet offers excellent drying speed, maintains durability without causing burrs due to film formation, and minimizes transfer. The problem to be solved

[0013] The embodiments of the present invention aim to enhance user convenience by providing a hair cosmetic in a water-soluble liquid form, which allows for easy portability and even application to the hair, as well as rapid absorption and drying.

[0014] In addition, we aim to develop a hair cosmetic that maintains durability by preventing burrs caused by film formation, and exhibits excellent drying speed and minimal transfer despite not containing ethanol.

[0015] In addition, it is quickly absorbed and dries into the hair to naturally cover gray hair and thinning hair.

[0016] In addition, by using a styrene-based film-forming agent or an acrylate-based film-forming agent that does not contain ethanol, we aim to provide a cosmetic composition for hair that has good durability and does not produce burrs.

[0017] In addition, we intend to provide hair cosmetics in various forms, such as mists, serums, and gels. means of solving the problem

[0018] According to one aspect of the present invention, a cosmetic composition for hair in the form of a water-soluble liquid, characterized by comprising an aqueous phase, a thickening agent, a pigment, a surfactant, and a film-forming agent, may be provided.

[0036] Referring to FIGS. 1 to 10, a cosmetic composition for hair in the form of a water-soluble liquid according to one embodiment of the present invention may largely comprise an aqueous phase, a thickening agent, a pigment, a surfactant, and a film-forming agent.

[0037] The above aqueous phase may comprise purified water, polyol, and a preservative.

[0038] The above-mentioned thickening agent may comprise magnesium aluminum silicate.

[0039] The above magnesium aluminum silicate may be included in an amount of 0.8% to 2.0% by weight.

[0040] The above surfactant may comprise polyglyceryl-3 polyricinoleate.

[0041] The above polyglyceryl-3 polyricinoleate has an HLB value of 3 to 5 and may be included in an amount of 1% to 5% by weight.

[0042] The above film-forming agent may comprise a polyacrylate-21 copolymer.

[0043] The above polyacrylate-21 copolymer may be included in an amount of 10% to 40% by weight.

[0044] And a method for preparing a water-soluble liquid form hair cosmetic composition according to one embodiment of the present invention may comprise the steps of: adding a polyol to purified water and heating it; adding magnesium aluminum silicate and dispersing and dissolving it using a disperser; adding polyglyceryl-3 polyricinoleate and dispersing and dissolving it; cooling to 50°C or lower and then adding and mixing a polyacrylate-21 copolymer, a pigment, and a preservative; and removing bubbles after mixing.

[0046] Experimental Example 1. Comparative experiment according to polyacrylate-21 content

[0047] The formulations in Table 1 below represent Experiments 1 through 4, in which a comparison was performed based on the content of polyacrylate-21.

[0048] ingredient Experiment 1 Experiment 2 Experiment 3 Experiment 4 purified water To 100 polyol 5.0 5.0 5.0 5.0 Magnesium aluminum silicate 1.5 1.5 1.5 1.5 Polyglyceryl-3 polyricinoleate 2.5 2.5 2.5 2.5 Polyacrylate-21 15.0 20.0 25.0 30.0 pigment 10.0 10.0 10.0 10.0 preservatives Appropriate amount Appropriate amount Appropriate amount Appropriate amount

[0049] Magnesium aluminum silicate may be included in an amount of 0.8% to 2.0% by weight. If the amount is less than 0.8% by weight, it may be difficult to form the viscosity of the formulation, and if the amount exceeds 2.0% by weight, it may clump upon application and the drying speed may be slow. In Table 1, it was set to 1.5% by weight.

[0050] The content of polyglyceryl-3 polyricinoleate may vary depending on the pigment content, but it is set to 2.5% by weight when the pigment content is 10% by weight. Depending on the pigment content, it may be added in an amount of 1% to 5% by weight; if it is less than 1% by weight, pigment banding may occur. If it exceeds 5% by weight, stickiness may occur and the drying speed may be slowed down.

[0051] Polyacrylate-21 was tested starting from 10 wt%, but the drying speed was slow, so it was not recorded in the table.

[0052] The manufacturing process of the formulation in Table 1 above is as follows. First, polyol is added to purified water and heated to 75–80°C. Then, magnesium aluminum silicate is added and dispersed and dissolved using a disperser at 500 rpm for 5 minutes. After confirming dispersion and dissolution, polyglyceryl-3 polyricinoleate is added and dispersed and dissolved at 500 rpm for 2 minutes.

[0053] Next, after cooling to 50°C or lower, polyacrylate-21, pigment, and preservative were added and mixed uniformly at 800 rpm for 10 minutes. Afterward, air bubbles were removed to prepare the cosmetic compositions of Experiments 1 to 4.

[0054] Figure 2 is an image showing the contents of Experiments 1 to 4. As shown in Figure 2, Experiments 1 and 4 had a thin consistency and separated when left for a long time, and Experiment 1 showed problems such as clumping and powder shedding when applied to hair due to the precipitation of pigments and film-forming agents.

[0055] Figure 3 is an image showing the drying speed after evenly applying 0.5g of the contents of each of experiments 1 to 4 onto a glass plate. Experiments 1 and 4 had very slow drying speeds due to their thin consistency, while experiments 2 and 3 showed very fast drying speeds, confirming that there was no sticking.

[0056] Figure 4 shows the results of measuring transfer at regular time intervals after applying the contents to hair to verify the drying speed of Experiments 2 and 3. Experiments 2 and 3 were applied to the hair simultaneously 10 times and dried at room temperature for approximately 1 minute; afterward, the drying status was checked at 30-second intervals by pressing the hair onto white paper with uniform pressure.

[0057] As shown in Figure 4, in the case of Experiment 3, almost no transfer was observed after 60 seconds, and there was no transfer after 90 seconds. Through these experimental results, it was confirmed that the content of the film-forming agent at 25 wt% was better than at 20 wt%.

[0059] Experimental Example 2. Comparative Experiment of Film-forming Agents

[0060] The formulation in Table 2 below was prepared by setting the content of the film-forming agent to 25% by weight as described above, selecting raw materials commonly used as film-forming agents, and presenting them in a table along with comparative examples.

[0061] ingredient Example 1 Comparative Example 1 Comparative Example 2 Comparative Example 3 purified water To 100 polyol 5.0 5.0 5.0 5.0 Magnesium aluminum silicate 1.5 1.5 1.5 1.5 Polyglyceryl-3 polyricinoleate 2.5 2.5 2.5 2.5 Polyacrylate-21 25 - - - Styrene / Acrylate Copolymer A - 25 - - Acrylate copolymer - - 25 - Styrene / Acrylate Copolymer B - - - 25 pigment 10 10 10 10 preservatives Appropriate amount Appropriate amount Appropriate amount Appropriate amount

[0062] Figure 5 is a photograph of the contents manufactured in Table 2 above.

[0063] As a result of the experiment, it was confirmed that Comparative Examples 1 and 2 had poor stability due to the precipitation of pigments and film formers in the formulation, whereas no precipitation was observed in Example 1 and Comparative Example 3.

[0064] Figure 6 shows the results of a test conducted by applying Example 1 and Comparative Example 3 to hair, excluding Comparative Example 1 and Comparative Example 2, which had poor stability.

[0065] Although there was no significant difference in appearance, it was observed that after application to hair, Comparative Example 3 showed a prominent color of the film-forming agent and turned white upon drying. In contrast, it was confirmed that Example 1 provided natural coverage.

[0066] Figure 7 is the result of measuring powder adhesion and detachment by applying the contents to hair and applying the same pressure stress to check the film-forming agent or pigment powder detachment of Example 1 and Comparative Example 3.

[0067] Example 1 and Comparative Example 3 were applied to hair 10 times simultaneously and dried at room temperature for about 1 minute. Then, a cotton pad was pressed with uniform pressure to compare powder residue, and powder shedding was checked by rubbing the area where the cotton pad was applied 10 times on white paper. In the case of Example 1, it was found that there was almost no powder residue or shedding after drying.

[0068] Through the comparative experiments above, it was found that polyacrylate-21, the film-forming agent used in Example 1, was the most superior when comparing overall stability, coverage, adhesion, powder residue, and powder shedding.

[0070] Experimental Example 3. Comparison with existing water-soluble liquid hair cosmetics

[0071] A comparison was conducted by applying Example 1 to hair and an existing commercially available water-soluble liquid hair cosmetic.

[0072] Existing products Example 1 ingredient Content ingredient Content purified water To 100 purified water To 100 Xanthan sword 0.2 Magnesium aluminum silicate 1.5 PEG-40 Hydrogenated Castor Oil 1.5 Polyglyceryl-3 polyricinoleate 2.5 Acrylate copolymer 25 Polyacrylate-21 25 ethanol 5 polyol 5 pigment 10 pigment 10 preservatives Appropriate amount preservatives Appropriate amount

[0073] Figures 8 and 9 show the results of comparing Example 1 and a conventional product after application to hair. In the case of the conventional product, gloss was observed after application and the hair clumped together and hardened, whereas in the case of Example 1, the hair was applied thinly strand by strand without clumping and a natural color was expressed.

[0074] Figure 10 shows the results of comparing the water repellency of the existing product and Comparative Example 1. After spraying water, the transfer to paper was compared. Transfer was observed in the case of the existing product, but it was confirmed that there was almost no transfer in the case of Example 1.

[0075] It was confirmed that Example 1 also has excellent water repellency. Since cleaning is done thoroughly when using a detergent such as shampoo, there is no need to worry about cleaning after use.

[0076] According to the water-soluble liquid form hair cosmetic composition and the method for manufacturing the same according to the embodiments of the present invention described so far, the hair cosmetic is provided in a water-soluble liquid form, making it easy to carry and allowing for even application to the hair; it can enhance user convenience by rapidly absorbing and drying; it can maintain durability by preventing burrs caused by film formation; and it can realize a hair cosmetic with excellent drying speed and minimal transfer even though it does not contain ethanol.

[0077] In addition, a cosmetic composition for hair can be provided that is rapidly absorbed and dried into the hair to naturally cover gray hair and thinning hair, and has good durability by using a styrene-based film-forming agent or an acrylate-based film-forming agent that does not contain ethanol, thereby preventing burrs.

[0078] In addition, hair cosmetics can be provided in various forms such as mist, serum, and gel.
