[0002] As living standards improve, people have new demands for convenience in their lives. Makeup remover wipes are disposable cleaning products made of non-woven fabric soaked in a mildly acidic makeup remover. They remove makeup by emulsifying it with surfactants and then wiping. Their liquid content is between that of makeup remover water and makeup remover milk, and their core ingredient is a nonionic surfactant, such as alkyl glucosides.

[0003] Makeup remover wipes are a great alternative to face wash and cleansing, especially when traveling, camping, or going to the gym where you can't always guarantee you'll be able to wash your face with just water and cleanser. They require no rinsing, are easy to use, and simply wipe your skin to remove makeup and dirt.

[0004] The active cleansing ingredients in existing makeup remover wipes are the same as those in regular facial cleansers, only capable of dissolving makeup oils and dead skin. While they can provide temporary relief, their effectiveness is not ideal. Common problems with existing makeup remover wipe technology mainly lie in the following aspects: (1) The use of strong surfactants such as SLS or soap base is highly irritating, leading to dry skin and allergies; (2) Lack of skin-nourishing ingredients, focusing only on cleansing while neglecting moisturizing and skin nourishment; (3) Existing wet wipe liquid often separates into layers due to oil-water separation, affecting the effect;

[0005] (4) Existing preparation methods involve multiple heating and emulsification steps, which are complex, costly and produce products that are not suitable for general consumer use. Summary of the Invention

Detailed Implementation

[0016] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] The present invention will be described in detail with reference to the following embodiments: Example 1

[0018] This embodiment provides an anti-stratification makeup remover wipe liquid, which comprises, by weight percentage: 70-80 parts water 5-10 parts glycerin 3-8 parts of PEG-7 glyceryl cocoate 2-5 parts jojoba oil Allantoin 0.1-0.5 parts Sodium hyaluronate 0.1-0.3 parts Xanthan gum 0.1-0.5 parts 0.1-0.3 parts of bisabolol Vitamin E 0.1-0.3 parts Preservative 0.1-0.3 parts.

[0019] In this embodiment, we chose water as the base, which can provide a liquid medium and is low in cost and safe. At the same time, in order to ensure the formula is lightweight, the weight of water is selected as 70-80 parts, which accounts for the main proportion of the makeup remover wipe liquid.

[0020] Existing technologies often use SLS or soap-based surfactants, which, while providing significant cleansing, are highly irritating and unsuitable for prolonged skin use. This invention utilizes PEG-7 glyceryl cocoate, a mild surfactant that offers high cleansing efficiency without damaging the stratum corneum. It effectively emulsifies makeup and sunscreen products, reducing damage to the skin's stratum corneum and significantly lowering the risk of skin irritation.

[0021] The formulation of this invention incorporates xanthan gum as a thickener, achieving uniformity and stability through microemulsion technology, thus enhancing its anti-stratification properties. As both a thickener and stabilizer, xanthan gum prevents liquid stratification, ensuring uniform release of active ingredients during use. This avoids the common problem of oil-water separation in existing makeup remover wipes, which negatively impacts effectiveness. Accelerated testing of the makeup remover wipes of this invention, with the addition of xanthan gum as a thickener, showed no stratification for up to 12 months, compared to only 3-6 months for existing products, demonstrating significant effectiveness.

[0022] In order to better achieve the effects of moisturizing, anti-allergy, and skin nourishing, and to provide a more comfortable user experience, our formula has been adjusted in the following aspects: Glycerin and sodium hyaluronate were selected as moisturizers. Glycerin provides immediate hydration, while sodium hyaluronate enhances long-lasting moisturization and prevents dry skin.

[0023] Jojoba oil mimics the skin's natural oils, gently dissolving stubborn makeup while providing a lubricating feel and enhancing comfort.

[0024] Vitamin E is an antioxidant that protects the skin from free radical damage, nourishes the skin and enhances its stability, and has moisturizing and skin-nourishing functions.

[0025] Allantoin and bisabolol are an anti-allergy combination. Allantoin can promote skin repair, while bisabolol soothes and reduces the risk of allergies.

[0026] The pH adjuster adjusts the pH of the makeup remover wipes to 5.5-6.5, ensuring the formula's microbial safety and skin-friendly pH, thus avoiding irritation.

[0027] The formula in this embodiment is based on the synergistic effect of multiple ingredients, which can achieve efficient cleansing, moisturizing, anti-allergy, skin nourishing and anti-delamination. Example 2

[0028] This invention provides an optimal formulation ratio for an anti-stratification makeup remover wipe liquid, wherein the makeup remover wipe liquid comprises, by weight percentage: 75 parts water 8 parts glycerin 5 parts PEG-7 glyceryl cocoate 3 parts jojoba oil Allantoin 0.2 parts Sodium hyaluronate 0.2 parts 0.3 parts xanthan gum 0.2 parts of bisabolol Vitamin E 0.2 parts 0.2 parts preservative pH adjuster adjusts the pH of makeup remover wipes to 6.0.

[0029] In the formulation of this invention, we selected 75 parts water as the solvent to provide the base liquid for the entire makeup remover wipe. Water is a low-cost, non-toxic, and harmless solvent, while ensuring the formula is lightweight and easily absorbed. 0.3 parts xanthan gum is used to thicken and stabilize the formula, prevent separation, ensure even distribution of the wipe liquid, and facilitate use.

[0030] Three parts jojoba oil dissolve oily makeup, providing a smooth feel and enhancing makeup removal efficiency, while mimicking skin's natural oils for nourishment. Eight parts glycerin provide powerful hydration, attracting and locking in moisture to prevent tightness after makeup removal and improve comfort. 0.2 parts sodium hyaluronate deeply moisturizes, increasing skin's moisture content and locking in water effectively, leaving skin soft and supple. 0.2 parts vitamin E provide antioxidant protection, shielding skin from environmental damage, nourishing the skin, and extending the product's shelf life.

[0031] PEG-7 glyceryl cocoate (5 parts) gently cleanses and effectively removes makeup and sunscreen without damaging the stratum corneum, reducing skin irritation. It also contains allantoin (0.2 parts) for anti-allergic and repairing effects, soothing the skin and reducing redness and itching. Bisabolol (0.2 parts) provides anti-inflammatory and soothing effects, reducing allergic reactions and enhancing anti-allergic properties, making it suitable for sensitive skin. A pH adjuster helps adjust to a skin-friendly pH of 6.0, reducing irritation and maintaining the skin barrier.

[0032] 0.2 parts of preservative are added to prevent microbial contamination and ensure product safety and stability.

[0033] In Examples 1-2, our formulations were based on gentleness, anti-lamination, and multi-functionality to provide a makeup remover wipe. However, different skin types, such as dry, oily, sensitive, and combination, have different needs for ingredients. Below, we will provide Examples 3-6 to adapt the makeup remover wipe formulation to different skin types, making it more precisely suitable for different skin types. Example 3

[0034] Since dry skin requires enhanced moisturizing and hydration, and to avoid excessive degreasing by cleansing ingredients, in this embodiment, we provide a suitable formula for makeup remover wipes for use on dry skin to better optimize the present invention.

[0035] A makeup remover wipe liquid that resists stratification, said makeup remover wipe liquid comprising, by weight percentage: 70 parts water 10 parts glycerin 4 parts PEG-7 glyceryl cocoate 5 parts jojoba oil Allantoin 0.2 parts Sodium hyaluronate 0.3 parts 0.3 parts xanthan gum 0.2 parts of bisabolol Vitamin E 0.3 parts 0.2 parts preservative 2 parts cetyl ethylhexanoate pH adjuster adjusts the pH of makeup remover wipes to 6.0.

[0036] In this embodiment, we use 70 parts of water as the base solvent; 0.3 parts of xanthan gum are used to achieve the anti-stratification effect; and 2 parts of cetyl ethylhexanoate are added as a emollient to replace part of the surfactant and reduce skin irritation.

[0037] In the remaining formula adjustments, we added 10 parts glycerin to enhance moisturizing, 0.3 parts sodium hyaluronate to deeply lock in moisture, 5 parts jojoba oil to enhance its oily moisturizing properties, and 0.3 parts vitamin E to achieve antioxidant and skin-nourishing effects.

[0038] PEG-7 glyceryl cocoate is selected at 4 parts to maintain gentle cleansing, allantoin at 0.2 parts to provide repair benefits, and bisabolol at 0.2 parts to soothe the skin.

[0039] Add 0.2 parts of preservative to extend the product's shelf life, and adjust the pH to 6.0 using a pH adjuster.

[0040] Because dry skin is prone to tightness and flaking, the formulation in this example enhances moisturizing and water-locking capabilities by increasing the proportion of glycerin and sodium hyaluronate; the addition of jojoba oil and cetyl ethylhexanoate provides an oily moisturizing effect, mimicking skin lipids and preventing damage to the stratum corneum. Compared to the formulations in Examples 1-2, the amount of surfactant is reduced, minimizing the risk of degreasing. Furthermore, clinical testing of the formulation shows that this adjustment can increase skin moisture content by more than 30% without stratification, while also accelerating 12-month stability testing. Example 4

[0041] Oily skin requires a focus on a refreshing feel and oil control, while avoiding clogged pores. Therefore, in this embodiment, we provide a suitable formula for makeup remover wipes for use on oily skin to better optimize the present invention.

[0042] A makeup remover wipe liquid that resists stratification, said makeup remover wipe liquid comprising, by weight percentage: 78 portions of water 5 parts glycerin 6 parts PEG-7 glyceryl cocoate 2 parts jojoba oil 0.1 part allantoin Sodium hyaluronate 0.1 parts 0.4 parts xanthan gum 0.1 part of bisabolol Vitamin E 0.1 part 0.2 parts preservative Caprylic / Capric Triglycerides (3 parts) 0.1 part tea tree essential oil pH adjuster adjusts the pH of makeup remover wipes to 5.5.

[0043] In the formulation of this embodiment, due to the slightly acidic nature of the oil-controlling agent, the pH is adjusted to pH 5.5.

[0044] There are two new ingredients: A: Caprylic / Capric triglyceride, 3 parts, a light oil that is easily emulsified; B: 0.1 parts tea tree oil can achieve natural oil control.

[0045] Among the other ingredients, we selected 78 parts water as the base solvent and 6 parts PEG-7 glyceryl cocoate to enhance cleaning power.

[0046] Five parts glycerin are used for moderate moisturizing, and 0.1 parts sodium hyaluronate is selected to avoid excessive moisturizing for oily skin. At the same time, two parts jojoba oil are added to use a light oil phase to suit oily skin.

[0047] Allantoin 0.1 parts, for basic repair; bisabolol 0.1 parts, for soothing; vitamin E 0.1 parts, for antioxidant effect; xanthan gum 0.4 parts, for anti-delamination; preservative 0.2 parts, to extend the service life.

[0048] This formula is designed for oily skin, reducing the glycerin and oil ratio to suit the acne-prone and oily texture of oily skin. The addition of caprylic / capric triglycerides provides a lightweight cleansing effect; the pH is adjusted to 5.5 to help maintain the skin's slightly acidic barrier and reduce sebum secretion; tea tree oil provides natural antibacterial and oil-controlling effects. Compared to the formulas in Examples 1-2, the cleansing power is improved while maintaining gentleness, making it suitable for removing waterproof makeup, reducing oiliness by 20%, and eliminating the risk of acne. Example 5

[0049] Sensitive skin requires minimal irritation and enhanced anti-allergy and repairing ingredients. In this embodiment, we provide a makeup remover wipe formulation suitable for use on sensitive skin to better optimize the present invention.

[0050] A makeup remover wipe liquid that resists stratification, said makeup remover wipe liquid comprising, by weight percentage: 75 parts water 7 parts glycerin 3 parts PEG-7 glyceryl cocoate 2 parts jojoba oil 0.5 parts allantoin Sodium hyaluronate 0.2 parts 0.3 parts xanthan gum 0.3 parts of bisabolol Vitamin E 0.2 parts 0.1 parts preservative Centella asiatica extract 0.2 parts Polyglycerol-3 1 part pH adjuster adjusts the pH of makeup remover wipes to 6.0.

[0051] In the above formula, we adjusted the pH to 6.0 with a pH adjuster and added the following ingredients: 0.2 parts of Centella Asiatica extract for anti-inflammatory and repairing effects, and 1 part of polyglycerol-3. Through surfactant-free replacement technology, we achieved zero-irritation makeup removal.

[0052] PEG-7 glyceryl cocoate 3 parts, minimum irritant surfactant; allantoin 0.5 parts, maximum repair; bisabolol 0.3 parts, strengthening and soothing; preservative 0.1 parts, using low preservatives to reduce skin irritation.

[0053] Other ingredients: 75 parts water as the base solvent, 7 parts glycerin, 2 parts jojoba oil, 0.2 parts sodium hyaluronate, 0.2 parts vitamin E, and 0.3 parts xanthan gum.

[0054] Because sensitive skin is prone to redness and allergies, the adjusted formula in this example uses a minimal amount of surfactants and adds Centella asiatica extract to enhance its anti-inflammatory effect; the proportions of allantoin and bisabolol are increased to the maximum for synergistic soothing. The amount of preservatives is reduced to minimize chemical irritation. Compared to the formulas in Examples 1-2, anti-allergy properties are improved, with a 40% reduction in allergy rates in clinical tests, and zero-irritation makeup removal is achieved by replacing some surfactants with polyglycerol-3. Example 6

[0055] In this embodiment, we conducted a specific formulation study for combination skin. Combination skin requires a balance between T-zone cleansing and U-zone moisturizing to achieve a zoned care effect. Therefore, we provide a makeup remover wipe formulation suitable for oily skin to better optimize the present invention.

[0056] A makeup remover wipe liquid that resists stratification, said makeup remover wipe liquid comprising, by weight percentage: 76 parts water 8 parts glycerin 5 parts PEG-7 glyceryl cocoate 3 parts jojoba oil Allantoin 0.2 parts Sodium hyaluronate 0.2 parts 0.3 parts xanthan gum 0.2 parts of bisabolol Vitamin E 0.2 parts 0.2 parts preservative 2 parts of decyl glucoside 0.5 parts aloe vera extract pH adjuster adjusts the pH of makeup remover wipes to 5.8.

[0057] In this formula, we added 2 parts decyl glucoside for gentle surfactant action and balanced cleansing; and 0.5 parts aloe vera extract for zoned regulation. Combination skin tends to have an oily T-zone and a dry U-zone. This formula uses decyl glucoside as a co-surfactant to provide balanced cleansing power; aloe vera extract helps regulate oil and moisturize. The pH of 5.8 is also closer to the skin's natural value, avoiding zoned discomfort. Compared to the formulas in Examples 1-2, this formula has broader applicability. User experience shows a 15% improvement in T-zone cleansing efficiency, while U-zone moisturizing remains unchanged. The optimized formula is more suitable for combination skin.

[0058] In Examples 1-6 above, the preservative is phenoxyethanol; the pH adjuster is citric acid. Example 7

[0059] An anti-delamination makeup remover wipe includes the anti-delamination makeup remover wipe liquid described in Examples 1-6, wherein the makeup remover wipe liquid is applied to the makeup remover wipe, and the anti-delamination makeup remover wipe includes the anti-delamination makeup remover wipe liquid and spunlace nonwoven fabric. Example 8

[0060] This embodiment provides a method for preparing anti-delamination makeup remover wipes, comprising anti-delamination makeup remover wipe liquid and spunlace nonwoven fabric. Specifically, the preparation method includes the following steps: S1: Utilizing polyglycerol fatty acid ester (PGFE) to form a bicontinuous microemulsion, replacing traditional surfactants. Specifically, PEG-7 glyceryl cocoate is mixed with PGFE (2-4 parts added) at room temperature, adjusting the hydrophilic-lipophilic balance HLB value to 12-14 to form a microemulsion with low temperature dependence. This step ensures uniform dispersion of the oil and water phases, preventing stratification from the outset, and requires no heating, protecting heat-sensitive components such as vitamin E and bisabolol. S2: Apply ultrasound and ultraviolet light to the mixture. Set the ultrasound frequency to 20-40kHz and the ultraviolet light wavelength to 254nm. Treat for 10-15 minutes to completely dissolve the xanthan gum and refine the droplet size to the nanoscale, thereby enhancing the homogeneity and stability of the wetting solution. At the same time, perform preliminary sterilization and reduce the amount of preservatives used in the subsequent process. S3: Microwave-assisted impregnation with a frequency of 2.45GHz is used to immerse the spunlace nonwoven fabric in the mixed solution and microwave it for 1-2 minutes. The power is set to 500W to ensure that the nonwoven fabric is evenly loaded and that the microwave heating is gentle. S4: After impregnation, vacuum degassing is performed to remove air bubbles, with the pressure set at 0.1 MPa and the time set at 5 minutes to prevent stratification during storage, and then sterilized by γ-irradiation with a dose of 10-15 kGy. S5: Packaging is carried out at 25°C, and integrated real-time pH monitoring is used to control the pH between 5.5 and 6.5. Weight detection is carried out through an automated system to ensure that the solution load of each wipe is consistent.

[0061] In step S1 above, a bicontinuous microemulsion is formed by adding 2-4 parts of polyglycerol fatty acid ester (PGFE), exhibiting stable hydrophilic-lipophilic balance (HLB) values ​​and low temperature dependence. Compared to conventional processes using POE-type surfactants, this avoids the risk of stratification at high temperatures and improves cleaning efficiency. For the formulations in Examples 1-6, ensuring uniform mixing of the jojoba oil and aqueous phase enhances resistance to stratification.

[0062] In step S2, ultrasonic waves break up aggregated particles, and ultraviolet light sterilizes them. These actions work synergistically to rapidly dissolve xanthan gum, reducing the time by 50% and improving solution stability. Accelerated testing shows no stratification for up to 12 months. This method is more efficient than traditional stirring and reduces reliance on chemical emulsifiers, thus lowering costs.

[0063] In steps S3-S5, microwaves promote liquid penetration into the nonwoven fibers, improving loading efficiency—specifically, increasing the loading rate by 20%—while maintaining ingredient activity and preserving the moisturizing properties of allantoin and sodium hyaluronate. Gamma irradiation provides thorough sterilization with a 99.9% kill rate, eliminating the need for high temperature and pressure, thus avoiding degradation of heat-sensitive ingredients. It is safer than chemical preservatives, especially suitable for formulas for sensitive skin, reducing the risk of allergies. Room temperature operation and automated quality control reduce energy consumption and labor costs while ensuring product compliance with ISO and GMPC standards.

[0064] Overall, these makeup remover wipes have been optimized for anti-lamination, stability, and gentleness, making them suitable for all skin types.

[0065] Therefore, the method for preparing anti-stratification makeup remover wipes provided by the present invention, by integrating microemulsion, ultrasound, microwave, and irradiation technologies, achieves the following beneficial effects for the anti-stratification requirements of the formulation of the present invention: (1) The method for preparing anti-stratification makeup remover wipes provided by the invention enhances the anti-stratification property, and the microemulsion and homogenization treatment ensure the stability of the oil-water phase, thus solving the traditional stratification problem; (2) The preparation method of the anti-layering makeup remover wipes provided by the invention effectively shortens the process time, is suitable for high-speed production lines, and improves efficiency; (3) The method for preparing anti-stratification makeup remover wipes provided by the invention can reduce heating and the use of preservatives, thereby reducing production costs; (4) The method for preparing the anti-layering makeup remover wipes provided by the invention uses low-temperature treatment and irradiation sterilization to maintain the integrity of the ingredients, making the product safer and gentler, and suitable for sensitive skin; (5) The preparation method of the anti-layering makeup remover wipes provided by the invention ensures that the performance of each wipe is uniform, the product consistency is high, and the quality is greatly improved by real-time quality control.

8. A makeup remover wipe with anti-layering properties, comprising the makeup remover wipe liquid with anti-layering properties as described in any one of claims 1-7, characterized in that, The makeup remover wipes are applied to makeup remover wipes.

9. The makeup remover wipes with anti-lamination properties according to claim 8, characterized in that, The makeup remover wipes also contain spunlace nonwoven fabric.

10. A method for preparing anti-delamination makeup remover wipes, comprising the anti-delamination makeup remover wipe liquid of claim 9 and spunlace nonwoven fabric, characterized in that, The preparation method includes the following steps: S1: Mix PEG-7 glyceryl cocoate with PGFE at room temperature and adjust the hydrophilic-lipophilic balance value to 12-14 to form a microemulsion with low temperature dependence; S2: Apply ultrasound and ultraviolet light to the mixture. Set the ultrasound frequency to 20-40kHz and the ultraviolet light wavelength to 254nm. Treat for 10-15 minutes to completely dissolve the xanthan gum and refine the droplet size to the nanoscale, thereby enhancing the homogeneity and stability of the wetting solution. At the same time, perform preliminary sterilization and reduce the amount of preservatives used in the subsequent process. S3: Microwave-assisted impregnation with a frequency of 2.45GHz is used to immerse the spunlace nonwoven fabric in the mixed solution and microwave it for 1-2 minutes. The power is set to 500W to ensure that the nonwoven fabric is evenly loaded and that the microwave heating is gentle. S4: After impregnation, vacuum degassing is performed to remove air bubbles, with the pressure set at 0.1 MPa and the time set at 5 minutes to prevent stratification during storage, and then sterilized by γ-irradiation with a dose of 10-15 kGy. S5: Packaging is carried out at 25°C, and integrated real-time pH monitoring is used to control the pH between 5.5 and 6.

5. Weight detection is carried out through an automated system to ensure that the solution load of each wipe is consistent.
