Description

Technical Field

[0001] This invention relates to a natural-looking liquid eyeliner and its preparation method. Background Technology

[0002] Liquid eyeliner, as an important product in eye makeup, has long been a common category in the cosmetics industry. It enhances the three-dimensionality of the eyes, makes them appear larger, and creates a refined makeup look by outlining the eye contour. However, existing liquid eyeliner products have some significant shortcomings in practical use, especially regarding their natural finish and everyday applicability.

[0003] First, traditional liquid eyeliner often appears too heavy or deliberate, giving the impression of "over-dressing." Many liquid eyeliners have high color saturation, which can easily create obvious color blocks after application, making it difficult to blend into a natural makeup look. Instead, it may create a heavy and uncoordinated feeling in the eye makeup, especially for those who want a light and natural look. The effect of traditional liquid eyeliner is often too emphasized and does not conform to the trend of everyday makeup.

[0004] Secondly, some liquid eyeliners fall short in terms of staying power and comfort. Due to improper ingredient ratios, some liquid eyeliners may smudge or fade during use, which is extremely inconvenient for daily use. This is especially true for oily skin or when worn for extended periods, as liquid eyeliner tends to smudge around the eyes, affecting the overall refinement of the makeup.

[0005] Furthermore, traditional liquid eyeliners have a relatively simple texture, often relying on strong pigments and high concentrations of polymers to increase their staying power. This can increase the burden on the skin. For consumers with sensitive skin or those who use them for extended periods, excessive chemicals or preservatives may trigger allergies or other skin discomfort.

[0006] Furthermore, existing liquid eyeliners often lack moisturizing and repairing properties. The skin around the eyes is delicate, and long-term use of cosmetics can easily lead to dryness, fine lines, and other problems. Therefore, a liquid eyeliner product that can both satisfy the needs of eye makeup and care for the delicate skin around the eyes is particularly important. Summary of the Invention

[0007] The purpose of this invention is to provide a natural-looking eyeliner and its preparation method, which can both enlarge the eyes and maintain a natural makeup look. This not only meets the market demand for natural makeup and high-performance eyeliner, but also solves the technical defects of existing eyeliner products in terms of durability, comfort and safety.

[0008] The technical solution adopted by this invention to solve its technical problem is:

[0009] A natural-looking eyeliner, comprising the following ingredients: water, jojoba oil, hyaluronic acid, micro-pearl particles, witch hazel extract, plant-derived pigments, polymer components, preservatives, glycerin, butylene glycol, polyvinyl alcohol, surfactants, fragrance, and bauxite.

[0010] Preferably, the ingredients include the following components in parts by weight: jojoba oil 5%-10%, hyaluronic acid 0.1%-0.5%, micro-pearl particles 1%-3%, witch hazel extract 0.5%-1%, plant-derived pigments 1%-3%, polymer components 2%-5%, preservatives 0.5%-1%, glycerin 2%-5%, butylene glycol 2%-4%, polyvinyl alcohol 1%-2%, surfactants 0.5%-1%, fragrances 0.1%-0.3%, bauxite 0.5%-1%, and the balance being water.

[0011] Preferably, the micro pearlescent particles have a particle size of 1μm-10μm and are made of natural mineral materials such as mica or titanium dioxide.

[0012] Preferably, the polymer component is a water-soluble polymer.

[0013] Preferably, the preservative is phenoxyethanol, ethylhexylglycerin, or a mixture thereof.

[0014] Preferably, the hyaluronic acid has a molecular weight of 5000-20000 Daltons.

[0015] Preferably, the polyvinyl alcohol is water-soluble polyvinyl alcohol with a molecular weight of 20,000-100,000 Daltons.

[0016] Preferably, the concentration of the witch hazel extract is 0.7%-0.9%, and the purity of the bauxite is greater than 95%.

[0017] Preferably, the surfactant is a nonionic surfactant selected from polyethylene glycol fatty acid esters or mixtures thereof.

[0018] Another technical problem to be solved by the present invention is to provide a method for preparing a natural-looking eyeliner, comprising the following steps:

[0019] Add water and polyvinyl alcohol to a mixing container and stir at low speed until the polyvinyl alcohol is completely dissolved, forming a transparent aqueous phase;

[0020] Slowly add hyaluronic acid to the aqueous phase and continue stirring until the hyaluronic acid is completely dissolved in the aqueous phase to form a homogeneous solution;

[0021] Mix jojoba oil, glycerin, and butylene glycol together and heat to 40-50°C while stirring until all ingredients are fully combined.

[0022] Gradually add the plant-derived pigments and witch hazel extract, and continue stirring to ensure even distribution of the pigments and extracts;

[0023] Tiny pearlescent particles are added to butanediol and ultrasonically dispersed using an ultrasonic treatment device until the pearlescent particles are completely dispersed and reach a uniform state.

[0024] Add the well-dispersed pearlescent particles to the oil phase and stir thoroughly to ensure that the pearlescent particles are evenly distributed in the oil phase.

[0025] After the aqueous phase and oil phase are prepared separately, the oil phase is slowly added to the aqueous phase while stirring at a speed of 1000-1500 rpm until a stable emulsion system is formed.

[0026] Continue stirring for 5-10 minutes to ensure the water and oil phases are fully combined;

[0027] Add the polymer component to the emulsion system and continue stirring to ensure uniform dispersion;

[0028] Add surfactants, fragrances, and preservatives, and adjust the pH to 5.5-6.5;

[0029] Add bauxite to the emulsion and continue stirring until the bauxite is evenly dispersed and the system does not separate into layers;

[0030] Large particles of impurities are removed by sieving.

[0031] The mixture was homogenized under high pressure using a homogenizer.

[0032] The processed eyeliner was cooled to room temperature and then subjected to a final quality check.

[0033] The cooled eyeliner liquid is filled into clean packaging containers, sealed, and sterilized.

[0034] The beneficial effects of this invention are:

[0035] By using micro-pearl particles, plant-derived pigments, and jojoba oil, this formula achieves a more natural eyeliner effect, avoiding overly bright and heavy colors, resulting in a softer and more natural eye makeup look. The micro-pearl particles provide a delicate shimmer, giving the eyeliner a soft, three-dimensional look on the eye contour. The use of plant-derived pigments allows the eyeliner color to adhere better to the skin, avoiding the overly made-up look that can occur with traditional liquid eyeliners. Polymer components (such as polyvinyl alcohol) help the eyeliner adhere better to the skin, enhancing its durability and preventing smudging or melting. Furthermore, witch hazel extract has astringent and soothing properties, strengthening the stability of the eyeliner and helping to reduce the impact of external environmental factors (such as oil and sweat) on its durability.

[0036] By incorporating moisturizing ingredients such as jojoba oil and hyaluronic acid, this product helps to hydrate and repair the delicate skin around the eyes. Jojoba oil deeply nourishes and maintains the skin's oil-water balance, while hyaluronic acid forms a moisturizing film to keep the skin around the eyes hydrated and reduce dryness or discomfort caused by eyeliner. The formula also includes natural ingredients such as witch hazel extract and plant-derived pigments, which are skin-friendly and gentle, reducing the likelihood of allergic reactions around the eyes. Furthermore, the use of preservatives ensures product stability and protective efficacy, while extending the product's shelf life without compromising skin safety.

[0037] The addition of butylene glycol, glycerin, and surfactants helps improve the fluidity and smoothness of the eyeliner, making it easier to apply evenly and enhancing the overall ease of use. Furthermore, the use of fragrance provides a subtle aroma, making the makeup application process more pleasant. By using gentle, moisturizing ingredients such as jojoba oil and hyaluronic acid, this formula effectively addresses potential discomfort to the delicate skin around the eyes caused by eyeliner, improving product comfort and making it suitable for long-term wear, especially gentle on sensitive skin. The addition of bauxite helps improve the color effect, allowing the eyeliner to blend better with the skin after application, enhancing the naturalness of the color while avoiding potential color discrepancies. The properties of bauxite allow the eyeliner to maintain a proper balance between color saturation and transparency, ensuring a natural yet layered eye makeup look. Specific implementation methods

[0088] Experimental Example

[0089] Experimental materials:

[0090] The eyeliners in Examples 1-4 (each representing a different formula).

[0091] Commonly available liquid eyeliners (as a control group).

[0092] Participants: 40 healthy women aged 20-40 with no history of eye allergies.

[0093] Experimental equipment: standardized cosmetic reagent kits, microscope, skin reaction tester, and smudge detection equipment.

[0094] Natural Makeup Look Test:

[0095] Experimental design: Each participant will apply the eyeliner from Examples 1-4 and the control group eyeliner to both eyes (randomized). Standardized makeup tools will be used to apply the eyeliner according to the instructions.

[0096] Evaluation method: Three professional makeup artists will score the naturalness of the makeup (1-10 points, with 10 being the most natural). The scoring criteria include: eyeliner color, evenness, naturalness, and suitability to the shape of the eyes.

[0097] Data analysis: SPSS software was used to analyze the data and compare the score differences between the groups.

[0098] The natural makeup look is rated as follows:

[0099] Types of liquid eyeliner Number of participants Average rating Standard deviation Rating range Example 1 40 8.5 0.9 7-10 Example 2 40 9.0 0.7 8-10 Example 3 40 8.2 1.1 6-10 Example 4 40 8.7 0.8 7-10 Market control group 40 6.5 1.3 5-8

[0100] The results showed that the eyeliners in Examples 1-4 all achieved high scores in terms of naturalness (average score 8.2-9.0), significantly better than commonly available eyeliners (average score 6.5). In particular, Examples 2 and 4, due to the inclusion of natural plant ingredients (such as witch hazel extract and jojoba oil) in their formulas, gave the eyeliners a more natural and softer effect.

[0101] Smudge test:

[0102] Experimental Design: After applying liquid eyeliner, participants performed routine activities such as opening and closing their eyes, blinking, and facial muscle movements. Following the experiment, the eyeliner's durability on the eyelids was examined under a microscope, and any smudging was recorded.

[0103] Test method: Observe and record the clarity of the eyeliner and whether there is smudging, fading or spreading at 4 hours, 8 hours and 12 hours after using the liquid eyeliner.

[0104] Data analysis: Compare the smearing situation of Examples 1-4 with the control group, and count the frequency and severity of smearing.

[0105] The incidence of smearing is as follows:

[0106]

[0107] In the smudging assessment after 4 hours, Examples 1-4 all demonstrated strong durability, with good eyeliner clarity. Examples 1 and 3, due to their polymer components, provided additional stability, resulting in almost no smudging. In contrast, the control group's eyeliner began to show significant smudging after 8 hours (smudging area exceeding 20%).

[0108] Allergy test:

[0109] Experimental Design: Local allergy testing was conducted. Forty-eight hours prior to the experiment, participants applied each type of eyeliner to the inside of their forearms and observed for any allergic symptoms such as redness, swelling, itching, or stinging.

[0110] Testing standards: Based on international cosmetic safety standards, observe whether obvious allergic reactions occur within 48 hours, and record and analyze the frequency of allergic reactions.

[0111] Data analysis: The proportion of allergies caused by each type of eyeliner was statistically analyzed, and the allergy incidence rate of Examples 1-4 was compared with that of the control group.

[0112] Allergic reactions are as follows:

[0113]

[0114] Examples 1-4 performed excellently in local allergy testing, with no allergic reactions observed in any participants. In contrast, approximately 5% of participants in the control group experienced mild redness and stinging, suggesting that this group of eyeliners may contain irritating ingredients (such as certain synthetic fragrances or preservatives). The natural ingredients, such as witch hazel extract, in Examples 1-4 significantly reduced the risk of allergic reactions.

[0115] Comfort test:

[0116] Experimental design: Participants recorded their eye comfort after using liquid eyeliner, including whether they felt tightness, dryness, stinging or discomfort.

[0117] Rating criteria: Comfort level is rated on a scale of 1 to 10 (10 being the most comfortable). Participants are required to rate the comfort level immediately after use and again after 2 and 4 hours.

[0118] Data analysis: The comfort performance of different eyeliner liquids was assessed using mean scores and standard deviations, and the differences between Examples 1-4 and the control group were compared.

[0119] The comfort ratings are as follows:

[0120]

[0121]

[0122] In the comfort test, the eyeliners in Examples 1-4 received higher scores (average score 8.0-9.0), with participants generally reporting no dryness, tightness, or irritation around the eyes, and maintaining good comfort even after prolonged wear. In contrast, the control group eyeliners had lower comfort (average score 6.0), with some participants reporting mild discomfort after use.

[0123] Through a series of comparative experiments, the eyeliners in Examples 1-4 demonstrated superior performance in the following aspects:

[0124] Natural Makeup Look: The eyeliners in Examples 1-4 exhibit a more natural makeup effect and fit the eye contour better, bringing users a more harmonious makeup effect.

[0125] No smudging: These liquid eyeliners exhibit remarkable smudging resistance, maintaining a clear eyeliner look for an extended period during daily activities.

[0126] Allergy testing: The eyeliners in Examples 1-4 did not elicit any allergic reactions in allergy tests, which is superior to eyeliners with conventional formulas.

[0127] Comfort: These liquid eyeliners offer greater comfort during wear, reducing dryness or discomfort, and are suitable for prolonged use.
