Description

Technical Field

[0001] This application relates to the field of cosmetic technology, and mainly to a children's soothing makeup remover balm and its preparation method. Background Technology

[0002] With increasing awareness of skincare among children, children's makeup products are becoming more widespread, leading to a growing demand for children's makeup removers. Children's skin barrier function is not yet fully developed, their stratum corneum is thinner, their sebaceous glands are less active, and they have lower tolerance to external stimuli. Therefore, children's makeup removers need to be effective in removing makeup while being gentle, soothing, and low-irritant.

[0003] Existing makeup remover products can be mainly divided into the following categories: Cleansing oil: Primarily composed of oils, it has strong makeup-removing power, but feels greasy on the skin. It requires emulsification before rinsing, making the process relatively complex. Incomplete emulsification can easily lead to residue, potentially causing skin irritation in children. Cleansing water: Primarily composed of surfactants and water, it is refreshing and non-greasy, but its makeup-removing power is relatively weak. It requires the use of cotton pads for wiping, and mechanical friction may damage the delicate skin barrier of children. Cleansing balm / lotion: Falls between the two, typically containing oils, surfactants, and water. However, most existing products contain a large amount of free water, requiring the addition of preservatives. Furthermore, long-term storage can easily lead to problems such as layering and particle growth.

[0004] Therefore, how to achieve long-term stable suspension and a non-irritating skin feel of water-soluble soothing powder while ensuring water-free safety remains a technical challenge that urgently needs to be solved. Summary of the Invention

[0005] One objective of this application is to provide a children's soothing makeup remover balm and its preparation method, which combines high safety with a good makeup removal experience.

[0006] To achieve the above objectives, the technical solution adopted in this application is: a children's soothing makeup remover balm, characterized in that, by weight percentage, the makeup remover balm comprises the following components: Phase A: 40.0%~60.0%, selected from one or more of squalane, caprylic / capric triglycerides, and jojoba seed oil; Phase B: 8.0%~15.0%, including natural waxes with melting points of 60℃~67℃ and natural high-melting-point waxes with melting points of 82℃~86℃; Phase C: 10.0%~20.0%, containing polyglycerol nonionic surfactants and hydrogenated lecithin; D phase: 8.0%~18.0%, containing C3-C5 diol as a grinding medium, and water-soluble soothing powder dispersed therein, wherein the particle size D90 of the water-soluble soothing powder is ≤5μm; Phase E: 0.5%~2.0%, containing tocopherol and bisabolol; The cleansing balm is an anhydrous, non-aqueous system free of free water, that is, a composite matrix system containing a polyol phase and a lipid phase. The water-soluble soothing powder, in the form of microparticles with a D90 ≤ 5 μm, is suspended in the system. Long-term stability is achieved synergistically through the dispersion of butylene glycol, the interfacial adsorption of hydrogenated lecithin, and the physical barrier of the B-phase three-dimensional wax network. Simultaneously, the microparticle size of D90 ≤ 5 μm is below the skin's tactile perception threshold, eliminating the gritty or "prickly" feeling during application, achieving an excellent "feel-free" skin sensation while ensuring high safety.

[0007] As a preferred embodiment, the natural wax in phase B is beeswax, and the natural high-melting-point wax is carnauba wax or candelilla wax. When rapidly cooled, beeswax and the high-melting-point wax synergistically form a dense, high-yield-stress three-dimensional microcrystalline network, significantly enhancing the physical anchoring ability for micron-sized particles and effectively preventing gravity settling under transport vibrations or temperature fluctuations.

[0008] As a preferred embodiment, in phase C, the polyglycerol nonionic surfactant is polyglycerol-10 oleate, with an amount of 12.0%~16.0%; and the amount of hydrogenated lecithin is 0.3%~1.0%. Specifically, polyglycerol-10 oleate undergoes a phase transition upon contact with water to form an O / W emulsion, which facilitates rinsing; hydrogenated lecithin self-assembles on the surface of the micropowder to form a monomolecular steric hindrance layer, preventing secondary agglomeration of particles, while simultaneously enhancing suspension stability in conjunction with the wax network.

[0009] As a preferred embodiment, the diol in phase D is butylene glycol, used in an amount of 8.0% to 15.0%; the water-soluble soothing powder is selected from one or more of oat β-glucan and allantoin, used in a total amount of 0.5% to 1.5%. Butylene glycol serves both as a grinding medium to achieve micronization and as a means to form competitive hydrogen bonds with the powder surface using its hydroxyl groups, inhibiting the re-agglomeration of particles after grinding; oat β-glucan and allantoin provide anti-inflammatory, soothing, and repairing effects, protecting children's skin while removing makeup.

[0010] As a preferred embodiment, the D phase further comprises octyl glycol in an amount of 0.3% to 0.8%. As an amphiphilic diol, octyl glycol has both moisturizing and preservative-enhancing functions. It enhances the preservative ability of the system by disrupting the cell membrane of microorganisms, thus meeting the high safety requirements of children's cosmetics without the need for traditional preservatives.

[0011] As a preferred embodiment, a method for preparing a cleansing balm as described in any of the above embodiments includes the following steps: S1: Using butanediol as the dispersion medium, water-soluble soothing powder is added to it. First, it is pre-ground by ultrasonic cavitation to D90≤20μm, and then finely ground by solid media to D90≤5μm to obtain the first micro powder slurry. During the grinding process, the hydroxyl groups of butanediol form competitive hydrogen bonds with the powder surface to inhibit the re-agglomeration of the micro powder after grinding. S2: Mix phases A, B, and C, heat to 80℃~85℃ and stir until completely transparent and homogeneous to obtain a lipid-phase mixture; S3: Cool the lipid phase mixture to 60℃~70℃, add the E phase, and then pump the first micro powder slurry into the main pot, start high shear homogenization, and obtain a homogeneous mixture. S4: After vacuum degassing the homogeneous mixture at a temperature of 60℃~70℃, it is filled into the final packaging container; S5: Cool the filled packaging container to 40℃~45℃ at a rate of 5℃~10℃ / min to form a three-dimensional crystal network of phase B in situ inside the packaging container and freeze the micro powder particles in situ. S6: Continue cooling to room temperature and let stand for 24-48 hours to obtain the children's soothing makeup remover balm.

[0012] In step S5, the cooling rate is 5℃~10℃ / min. This cooling rate can be achieved using a tunnel-type cooling device, where the filled packaging containers pass through the cooling tunnel sequentially, cooling at a rate of 5℃~10℃ / min to ensure uniform and rapid cooling of the product in each container, suitable for large-scale continuous production.

[0013] This application achieves long-term stable suspension of water-soluble soothing powder in an anhydrous system through the hydrogen bonding of butylene glycol, the interfacial anchoring of hydrogenated lecithin, the physical freezing of the double wax network, and the addition of fine particles.

[0014] As a preferred embodiment, in step S1, the ultrasonic pre-grinding power is 200~500W, and the time is 10~20min; the solid media grinding uses 0.3~0.5mm zirconia beads, and the cyclic grinding is carried out for 30~60min. The two-step graded micronization method efficiently obtains a non-intrusive particle size with D90≤5μm. The ultrasonic pre-grinding initially breaks down the particles, reducing subsequent energy consumption, while the media grinding achieves precise size control and avoids over-grinding, which can lead to excessively high particle surface energy and re-agglomeration.

[0015] As a preferred embodiment, in step S3, the high-shear homogenization rotation speed is 2000~3000 rpm, the time is 5~10 min, and the temperature is controlled at 60℃~70℃. This parameter range provides sufficient shear force to ensure uniform adsorption of hydrogenated lecithin on the micropowder surface, forming a complete and dense steric hindrance layer, effectively preventing secondary particle aggregation, while avoiding excessive shear damage to the wax phase structure.

[0016] Preferably, the particle size distribution width (Span) of the water-soluble soothing powder is ≤1.5, where Span = (D90 - D10) / D50. By controlling the particle size distribution width, the solubility difference between particles of different sizes is reduced, further suppressing particle size growth during storage.

[0017] As a preferred embodiment, in step S5, the cooling rate is 6℃~8℃ / min.

[0018] Compared with the prior art, the beneficial effects of this application are as follows: (1) This application achieves long-term physical stability of water-soluble soothing powder in anhydrous system through interface anchoring and wax crystal network freezing mechanism.

[0019] (2) This application micronizes water-soluble powder to D90≤5μm to achieve a critical particle size with no physical friction, and combines hydrogen bond competition mechanism to prevent agglomeration, eliminating the gritty feeling and "prickly" feeling when applying, thus meeting the requirements of children's skin care products for the ultimate gentle skin feel.

[0020] (3) The fat-soluble soothing ingredients (such as bisabolol) and water-soluble soothing ingredients (such as allantoin and oat β-glucan) in the makeup remover system of this application work synergistically to soothe the skin and reduce irritation while removing makeup, thus providing both high safety and a good makeup removal experience.

[0025] I. Source of Raw Materials

[0026] II. Implementation Examples Example 1 2.1 Formulation composition (total mass 100%):

[0027] The total amount of water-soluble soothing powder (oat β-glucan + allantoin micro powder) was 0.72%, falling within the range of 0.5% to 1.5%. Laser particle size analyzer analysis showed that the particle size distribution width (Span) of the water-soluble soothing powder in this embodiment was 1.2.

[0028] It is worth mentioning that in this application, the water-soluble soothing powder can be selected from one or more of oat β-glucan and allantoin. Oat β-glucan is a non-crystalline polysaccharide, which, through micronization to a D90≤5μm, combined with the dispersing effect of butylene glycol and the freezing of a three-dimensional wax network, can achieve long-term stable suspension. Allantoin is a crystalline small molecule, which, through micronization to a D90≤5μm, combined with the hydrogen-bonding competitive stabilization of butylene glycol and the freezing of a three-dimensional wax network, can also achieve long-term stable suspension.

[0029] 2.2 Preparation steps: S1 Non-aqueous phase fractional micronization and hydrogen bond stabilization: 1,3-Butanediol (1.5%) was added to a grinding jar, along with oat β-glucan (0.5%) and allantoin micron powder (0.22%), and mixed to form a high-concentration slurry. Ultrasonic pre-grinding was then performed (300W power, 15min) to ensure that the particle size D90 of the material was ≤20μm. The mixture was then transferred to a media grinder, and 0.3~0.5mm zirconia beads (70% filling rate) were added. The mixture was circulated and ground for 45min. The D90 was measured by a laser particle size analyzer and found to be ≤5μm, resulting in a high-concentration micronized slurry. The remaining 1,3-Butanediol (10.5%) was then added for dilution and stirred evenly to obtain the first micronized slurry. During the grinding process, the hydroxyl groups in the butanediol molecule formed competitive hydrogen bonds with the powder surface, shielding the direct hydrogen bond attraction between particles and preventing the re-agglomeration of the micronized powder after grinding.

[0030] S2 Lipid-phase melting: Add phase A (squalane, MCT, jojoba seed oil), phase B (beeswax, carnauba wax), and phase C (polyglycerol-10 oleate, sorbitan oleate, hydrogenated lecithin) to the main pot, heat to 82±2℃, and stir (500rpm) until completely transparent and homogeneous to obtain a lipid-phase mixture.

[0031] S3 Mixing and Homogenization: Cool the lipid phase mixture in the main pot to 65±2℃, add the E phase (tocopherol, bisabolol), and stir until homogeneous. Then pump the first micronized slurry obtained in step S1 into the main pot and start high-shear homogenization (2500 rpm, 8 min) to obtain a homogeneous mixture.

[0032] S4 Degassing and Filling: The homogeneous mixture is degassed under vacuum at 65±2℃ (-0.08MPa, 10min), and then filled into the final packaging container (such as a hose or wide-mouth can).

[0033] S5 In-situ Curing: The filled packaging container is cooled to 42°C at a rate of 8°C / min, so that the beeswax and carnauba wax in phase B form a fine and uniform three-dimensional microcrystalline network in-situ within the packaging container, thus "freezing" the micro-powder particles in-situ within the network.

[0034] S6 Standing Curing: Let the cured product stand at room temperature for 36 hours to obtain the children's soothing makeup remover balm.

[0035] Example 2 The difference between Example 2 and Example 1 is that Example 2 includes the following step A1 between steps S1 and S2: Step A1: Add allantoin microcrystalline slurry with D90≤1μm (0.02% of the total formula on dry weight) to the first micro powder slurry obtained in step S1, stir at low speed until uniform (300rpm, 5min) to obtain the second micro powder slurry; and then pump the obtained second micro powder slurry into the main pot in step S3.

[0036] The preparation method of allantoin microcrystals with D90≤1μm is as follows: commercially available allantoin powder (D90≥20μm, content≥98.5%) is pulverized 2-3 times in an air jet mill at a pulverizing pressure of 0.6~0.8MPa and a classifying wheel speed of 4000-6000rpm to obtain allantoin microcrystals with D90≤1μm. The rest is consistent with Example 1.

[0037] Example 3 The difference between Example 3 and Example 1 is that phase D contains only oat β-glucan (0.72%) and does not contain allantoin micron powder; the rest is the same as in Example 1.

[0038] Example 4 The difference between Example 4 and Example 1 is that 1,3-butanediol in phase D is replaced with propylene glycol (12.0%), while the rest remains the same as in Example 1.

[0039] III. Comparative Example Comparative Example 1 The difference between Comparative Example 1 and Example 1 is that the water-soluble soothing powder was not micronized, while the remaining components and processes were consistent with those of Example 1.

[0040] Comparative Example 2 The difference between Comparative Example 2 and Example 1 is that Phase C does not contain hydrogenated lecithin, while the remaining components and processes are consistent with those of Example 1.

[0041] Comparative Example 3 The difference between Comparative Example 3 and Example 1 is that step S6 uses natural cooling, while the remaining components and processes are consistent with those of Example 1.

[0042] Comparative Example 4 The difference between Comparative Example 4 and Example 1 is that the water-soluble soothing powder (i.e., a mixture of oat β-glucan and allantoin micro powder without any grinding pretreatment) was directly added to the oil phase in dry powder form and stirred, without the S1 step (non-aqueous phase fractional micronization) of Example 1, and the water-soluble soothing powder was not pre-dispersed in butanediol. The remaining components and processes were consistent with those of Example 1.

[0043] IV. Performance Testing Methods 4.1 Particle size distribution test Method: Take 0.5g of sample, add 5mL of isopropanol to disperse, sonicate for 1min, and use a laser particle size analyzer (MalvernMastersizer 3000) to determine D10, D50 and D90, and calculate the particle size distribution width Span=(D90-D10) / D50.

[0044] Test nodes: after preparation (initial) and after 3 months of accelerated testing at 40℃.

[0045] 4.2 Stability Test High temperature acceleration: Referring to the "Technical Guidelines for Stability Testing and Evaluation of Cosmetics", the sample was placed in a constant temperature chamber at 40±2℃ and sampled for observation at 1, 2 and 3 months. The test items included: (1) Appearance: visually observe whether the cream is uniform, whether there is sedimentation or layering, and whether there is particle precipitation. (2) Centrifugal stability: centrifuge at 3000rpm for 30min and observe whether there is layering or oil release. (3) pH value: take 1g of sample and disperse it in 9mL of deionized water (preheated at 70℃) and measure it with a pH meter. (4) Cold and heat cycle test: the sample is placed at -15℃ for 24h → room temperature for 24h → heated at 40℃ for 24h as one cycle, and a total of 6 cycles are performed to observe the changes in the cream structure.

[0046] 4.3 Sensory evaluation test Methods: 30 parents of children (all with experience using children's makeup remover products) were recruited and blindly tested and scored (1-5 points, 5 points being the best). The test contents included: (1) Spreadability: 0.5g of sample was applied to the inside of the forearm and the smoothness of spreading was evaluated. (2) Friction / stinginess: After application, the presence of obvious particle friction was evaluated. (3) Rinsing: After adding an appropriate amount of warm water and emulsifying in circles, the residue was evaluated. (4) Skin feel after use: After rinsing and drying, the moisturizing / tightening feeling was evaluated 15 minutes later.

[0047] 4.4 Stimulation Test Methods: The "Chicken Embryo Villi-Allantoic Membrane Vascular Vascular Test (CAMVA)" in the "Cosmetic Safety Technical Specifications" was followed. 0.1g of the sample from Example 1 was evenly spread onto a filter paper disc with a diameter of approximately 1cm and placed on the chorioallantoic membrane of a 10-day-old chicken embryo. After 30 minutes of contact, bleeding, vascular lysis, and coagulation were observed and scored from 0 to 5 (0 for no irritation, 5 for strong irritation).

[0048] 4.5 Makeup Removal Efficacy Test Methods: Commonly used children's makeup products (including waterproof children's sunscreen, children's water-soluble lipstick, and stage makeup) were selected and tested at a concentration of 0.05 g / cm³. 2The product was evenly applied to the inner forearm of the subject and allowed to air dry for 10 minutes. 0.2g of the cleansing balm was then applied to the makeup-covered area, massaged in circular motions for 30 seconds, and then wiped clean with a damp cotton pad. Image analysis software was used to calculate the percentage of makeup residue, and the makeup removal effect was evaluated using the formula: "Makeup Removal Rate (%) = [1 - (Residual Area / Initial Application Area)] × 100%". Two commercially available children's cleansing balms, A (an imported brand) and B (a domestic brand), were used as controls. Each test was repeated three times, and the average value was taken.

[0049] V. Performance Test Results 5.1 Particle size stability

[0050] Comparative Examples 1 and 4 were not subjected to subsequent accelerated stability tests because their initial particle sizes far exceeded the requirements of this application.

[0051] Conclusion and analysis: The initial D90 of Examples 1-4 were all ≤5μm (4.7~4.9μm). After 3 months of accelerated growth at 40℃, the growth was only 0.3~0.5μm, the maximum D90 was ≤5.5μm, and the particle size distribution remained narrow (Span≤1.4).

[0052] Comparative Example 1 (without micronization) had an initial D90 of 38.5 μm, and Comparative Example 4 (dry powder added directly) had an initial D90 of 22.5 μm, both of which were unacceptable. Comparative Example 2 (without hydrogenated lecithin) showed a particle size increase of 5.0 μm, and Comparative Example 3 (natural cooling) showed a particle size increase of 2.4 μm, both significantly worse than the examples. The particle size stability of the examples in this application is significantly better than that of the comparative examples.

[0053] 5.2 Stability Test

[0054] Conclusion and Analysis: Examples 1-4 maintained a uniform appearance without precipitation after 3 months of accelerated treatment at 40℃, showed no stratification during centrifugation, and remained unchanged after 6 cycles of hot and cold cycling. Comparative Examples 1-4 all exhibited varying degrees of precipitation, stratification, or exudation. The pH values ​​of Examples 1-4 remained stable (change ≤0.1) after 3 months of accelerated treatment at 40℃. This indicates that the examples in this application maintain excellent physical stability under harsh conditions such as high temperature, centrifugal force, and alternating hot and cold cycles.

[0055] 5.3 Sensory evaluation (blind test with 30 participants, 1-5 points)

[0056] Conclusion and Analysis: The overall scores of Examples 1-4 are all ≥4.60. The friction score of Example 3 (containing only oat β-glucan) is 5.0. The friction score of Comparative Example 1 (unmicronized) is 1.2. The examples of this application show excellent performance in sensory evaluation (spreadability, friction, rinseability, and post-use moisturizing effect), and their overall scores are significantly better than those of the comparative examples.

[0057] 5.4 Analysis of Wax Crystal Network Structure The morphology of the wax crystal network is closely related to the cooling rate. In molten lipid systems, the faster the cooling rate and the greater the supercooling, the higher the nucleation rate is compared to the crystal growth rate, thus tending to form a fine, uniform, and dense microcrystalline network. Conversely, with slow cooling, the nucleation rate is lower, allowing sufficient time for crystal growth, easily resulting in large, irregular plate-like or spherical crystals. Example 1 used a cooling rate of 8°C / min, while Comparative Example 3 used natural cooling at ≤2°C / min. The cooling rate of Comparative Example 3 was slower than that of Example 1, resulting in inferior performance in centrifugal stability and particle size growth tests.

[0058] 5.5 Stimulation Test Results According to the CAMVA method described in 4.4, the irritation score (IS) of Examples 1-4 were all 0, indicating that they were non-irritating. This shows that the cleansing balm of this application is non-irritating to the eyes and mucous membranes, and meets the safety requirements for children's cosmetics.

[0059] 5.6 Shelf life estimation Based on the conservative model of Q10=3 in the "Technical Guidelines for Stability Testing and Evaluation of Cosmetics", the stability was qualified after 3 months of accelerated testing at 40℃, and the shelf life at room temperature (25℃) could be more than 24 months. In Example 1, after 3 months of accelerated testing at 40℃, the D90 only increased by 0.4μm (still ≤5.5μm), indicating that the actual shelf life may be even longer. Examples 2-4 also showed a similar trend.

[0060] 5.7 Makeup Removal Efficacy Test Results The makeup removal efficacy was tested according to the method described in 4.5, and the results are as follows:

[0061] Conclusion Analysis: Example 1 showed a makeup removal rate of over 94% for various types of children's makeup, significantly better than commercially available control products. This indicates that the makeup remover balm of this application, while ensuring gentleness and stability, possesses excellent makeup removal capabilities and can meet the daily makeup removal needs of children.
