Description

Technical Field

[0001] This application relates to the field of cosmetics, and more particularly to a high-viscosity cream-type skin care product, its preparation method, and the cosmetic product itself. Background Technology

[0002] With the continued expansion of the functional skincare market, high-viscosity skincare products (such as creams, masks, and other leave-on products) are increasingly favored by consumers due to their strong ability to carry active ingredients and their rich texture. However, existing high-viscosity products generally suffer from problems such as a heavy and sticky texture, poor penetration of active ingredients, and unsuitability for oily and acne-prone skin. Furthermore, they are prone to stability risks such as separation, oil separation, and texture deterioration during long-term storage, which seriously restricts their user experience and market acceptance.

[0003] Microfluidic technology achieves ultrafine and efficient homogenization of materials through high-pressure shearing, resulting in emulsions with narrow particle size distribution and significantly better stability than traditional processes. However, the industry generally believes that this technology is only suitable for low-viscosity systems. When processing high-viscosity materials, it easily leads to equipment blockage and unstable pressure, making continuous production difficult. Therefore, microfluidic technology is currently mostly limited to low-viscosity essences or raw material pretreatment and cannot be directly used for the preparation of high-viscosity creams with a viscosity ≥5000 mPa·s. To obtain a high-viscosity final product, existing processes still require the addition of thickeners and secondary curing after microfluidic treatment, failing to fully realize the potential of this technology in simplifying processes, improving texture, and enhancing permeability.

[0004] In the publicly disclosed patented technologies, microfluidics have consistently been relegated to an auxiliary process. For example, patent document CN113143827A discloses an anti-aging and anti-wrinkle face cream and its preparation method, in which microfluidic high-pressure homogenization is only used as a homogenization step after raw material premixing. Subsequent processes such as liquid nitrogen droplet formation and corona treatment are still required, making the process complex. Furthermore, the product's thickening relies on waxy raw materials, and there is still a risk of oil separation and stratification during long-term storage. Patent document CN121533945A discloses a sunscreen-enhancing emulsion composition and its preparation process based on microfluidic emulsification. It uses microfluidic technology to reduce the emulsion particle size to improve the sunscreen effect, but it still requires the addition of a polymeric thickener for post-thickening, making it impossible to achieve one-step preparation of high-viscosity products.

[0005] In summary, existing technologies only use microjets as an auxiliary or pre-process, failing to overcome the limitations of their application in high-viscosity systems. They still suffer from core technical defects such as cumbersome process flow, reliance on post-thickening, insufficient long-term product stability, and difficulty in achieving continuous production.

[0006] In view of this, there is an urgent need to provide a high-viscosity cream product to solve the above problems. Summary of the Invention

[0007] The purpose of this application is to provide a high-viscosity cream-type skin care product, its preparation method, and the skin care product itself, in order to solve the above-mentioned problems.

[0008] To achieve the above objectives, the first aspect of this application provides a high-viscosity cream-type skincare product, the raw materials of which, based on a total mass of 100%, include: 5%~30% oil phase components, 0.7%~5% nonionic emulsifier, 0.1%~1% associative thickener, 5%~20% humectant, with the balance being water and additives; The oil phase components include one or more of fatty alcohols, synthetic oils, silicone oils, and natural oils; The associative thickener includes at least one of the following: acrylate / C10-30 alkanol acrylate crosspolymer, hydroxyethyl acrylate / sodium acryloyl dimethyl taurate copolymer, acrylate / behenol polyether-25 methacrylate copolymer, and acrylate / stearyl polyether-20 methacrylate copolymer. The nonionic emulsifier includes one or more of polyglycerol-10 stearate, cetearyl alcohol polyether-20, glycerol stearate, PEG-100 stearate, cetearyl alcohol olive oil ester, and sorbitan olive oil ester.

[0009] Optionally, the high-viscosity cream-type skincare product meets at least one of the following conditions: (1) The fatty alcohols include one or more of cetyl alcohol, stearyl alcohol, cetearyl alcohol, and behenyl alcohol; (2) The synthetic oils include one or more of the following compounds: caprylic triglyceride, capric triglyceride, isononyl isononanoate, isododecane, and C10-18 fatty acid triglyceride compounds; (3) The silicone oil includes one or more of phenyl polytrimethylsiloxane and polydimethylsiloxane; (4) The natural oils include one or more of meadowfoam seed oil, jojoba seed oil and shea butter.

[0010] Optionally, the humectant may include one or more of polyol humectants and sugar humectants.

[0011] Optionally, the high-viscosity cream-type skincare product meets at least one of the following conditions: (1) The polyol moisturizer includes one or more of glycerin, 1,3-propanediol, polyethylene glycol-8 and glycerin polyether-26; (2) The sugar humectant includes one or more of trehalose and β-glucan.

[0012] Optionally, the mass ratio of the associative thickener, the nonionic emulsifier, and the fatty alcohol is 1:1.5-10:3-15.

[0013] Optionally, the adjuvants include one or more of preservatives, pH adjusters, and active ingredients. The mass percentage of the additive in the raw material is ≤5%.

[0014] Optionally, the viscosity of the high-viscosity cream-type skin care product is 5000-100000 mPa·s.

[0015] A second aspect of this application provides a method for preparing a high-viscosity cream-type skincare product as described above, comprising: The raw materials of the high-viscosity cream-type skin care product are heated and mixed to obtain a crude emulsion; The crude emulsion was subjected to microfluidic homogenization to obtain a high-viscosity cream-type skin care product.

[0016] Optionally, the heating temperature is 70~80℃; The pressure of the microjet homogenization process is 100~120MPa, and the number of cycles is 2-4.

[0017] A third aspect of this application provides a cosmetic product, including the aforementioned high-viscosity cream-type skincare product.

[0018] Compared with the prior art, the beneficial effects of this application include: The high-viscosity cream-based skincare and cosmetic products provided in this application have strong formula adaptability. Through the synergistic compounding of associative thickeners, emulsifiers, and oil phase components, a stable three-dimensional viscosity network is spontaneously constructed. The viscosity coverage is suitable for all categories of high-viscosity cream-based skincare formulations, such as face creams and masks. Furthermore, because the oil phase is sheared and dispersed to nanoscale particle size, the material exhibits a semi-transparent or softly opaque natural blue-toned texture, which is visually clear and delicate, and has a soft and comfortable feel. This gives the product a more distinctive and premium feel. The particle size uniformity is far superior to products made with traditional processes, and the long-term stability is outstanding. Moreover, there is no need to add a high content of solid oils, avoiding the sticky, pilling, and slippery feel defects of traditional high-viscosity skincare products, and the absorption efficiency is greatly improved.

[0019] The method for preparing high-viscosity cream-type skin care products provided in this application allows the viscosity of the raw material formulation to offset the viscosity-damaging effect of high shear of microjets, breaking the technical prejudice that microjets can only handle low-viscosity fluids. It is the first process to prepare high-viscosity cream-type skin care products in one step using microjets, realizing that after microjets, there is no need for additional thickening and maturation processes, and high-viscosity skin care products that meet the viscosity requirements can be obtained directly, simplifying the production process, while giving the product a unique appearance and skin feel, and improving product stability.

It should be understood that the following drawings only show some embodiments of this application and should not be regarded as a limitation on the scope of this application.

[0022] First, the solution provided in this application will be explained in more detail as follows: The first aspect of this application provides a high-viscosity cream-type skincare product, the raw materials of which, based on a total mass of 100%, include: 5%~30% oil phase components, 0.7%~5% nonionic emulsifier, 0.1%~1% associative thickener, 5%~20% humectant, with the balance being water and additives; Optionally, the oil phase component of high-viscosity cream-type skincare products, by weight, can be any value between 5% and 30% of 5%, comprising 5%, 6%, 7%, 8%, 9%, 10%, 11%, 12%, 13%, 14%, 15%, 16%, 17%, 18%, 19%, 20%, 21%, 22%, 23%, 24%, 25%, 26%, 27%, 28%, 29%, 30%, or 5% to 30%, and the nonionic emulsifier can be 0.7%, 0.8%, 0.9%, 1%, 1.1%, 1.2%, 1.3%, 1.4%, 1.5%, or 1%. The concentrations of the thickener can be any value between 0.7% and 5%, including 6%, 1.7%, 1.8%, 1.9%, 2%, 3%, 4%, 5%, or 0.7% to 5%. The concentrations of the associative thickener can be any value between 0.1%, 0.2%, 0.3%, 0.4%, 0.5%, 0.6%, 0.7%, 0.8%, 0.9%, 1%, or 0.1% to 1%. The concentrations of the humectant can be any value between 5%, 6%, 7%, 8%, 9%, 10%, 11%, 12%, 13%, 14%, 15%, 16%, 17%, 18%, 19%, 20%, or 5% to 20%. It is important to note that by screening specific types of associative thickeners, nonionic emulsifiers, and oil phase components, these three components, in specific proportions, can adapt to the high-shear environment of microfluidics, offsetting the viscosity loss caused by the destruction of the thickener structure due to shearing. After shearing, a three-dimensional viscosity network with tiny oil droplets as the cross-linking center is spontaneously reconstructed. This network is not a rigid cross-link, but relies on the reversible association of hydrophobic end groups at the oil / water interface to form a multi-layered topological structure with tiny oil droplets as the core. After microfluidic treatment, no additional thickener is needed, and no long curing time is required to achieve the viscosity requirements of high-viscosity creams in one step. If other types of thickeners, emulsifiers, or solid oils are replaced, or if any of the three components is missing, the effect of "obtaining a stable target high-viscosity product without post-thickening or curing after microfluidic treatment" cannot be achieved. The formulation combination of this invention is irreplaceable. The oil phase components include one or more of fatty alcohols, synthetic oils, silicone oils, and natural oils; The associative thickener includes at least one of the following: acrylate / C10-30 alkanol acrylate crosspolymer, hydroxyethyl acrylate / sodium acryloyl dimethyl taurate copolymer, acrylate / behenol polyether-25 methacrylate copolymer, and acrylate / stearyl polyether-20 methacrylate copolymer. The nonionic emulsifier includes one or more of polyglycerol-10 stearate, cetearyl alcohol polyether-20, glycerol stearate, PEG-100 stearate, cetearyl alcohol olive oil ester, and sorbitan olive oil ester.

[0024] In some embodiments, the humectant includes one or more of polyol humectants and sugar humectants.

[0025] In some embodiments, the high-viscosity cream-type skincare product meets at least one of the following conditions: (1) The polyol moisturizer includes one or more of glycerin, 1,3-propanediol, polyethylene glycol-8 and glycerin polyether-26; (2) The sugar humectant includes one or more of trehalose and β-glucan.

[0026] In some embodiments, the mass ratio of the associative thickener, the nonionic emulsifier, and the fatty alcohol is 1:1.5-10:3-15.

[0027] Optionally, the mass ratio of the associative thickener, nonionic emulsifier, and fatty alcohol can be any value between 1:1.5:3, 1:5:3, 1:10:3, 1:5:5, 1:5:10, 1:5:15, 1:10:15, or 1:1:1.5-10:3-15.

[0028] It is important to note that this ratio is the core condition for achieving microfluidic treatment without the need for post-thickening or aging.

[0029] In some embodiments, the adjuvants include one or more of preservatives, pH adjusters, and active ingredients. The mass percentage of the additive in the raw material is ≤5%.

[0030] Optionally, the mass percentage of the additive in the raw material can be any value of 0%, 1%, 2%, 3%, 4%, 5% or ≤5%.

[0031] In some embodiments, the viscosity of the high-viscosity cream-type skin care product is 5000-100000 mPa·s.

[0032] Optionally, the viscosity of high-viscosity creams and ointments can be any value between 5000 mPa·s, 10000 mPa·s, 50000 mPa·s, 100000 mPa·s, or 5000 mPa·s-100000 mPa·s.

[0039] The second aspect of this embodiment provides a method for preparing a high-viscosity cream-type skin care product, the specific steps of which are as follows: The aqueous and non-aqueous phases were heated to 80°C respectively, mixed and pre-emulsified to obtain a crude emulsion.

[0040] The viscosity of the crude emulsion is 44250 mPa·s; The viscosity of the high-viscosity cream-type skin care product is 30430 mPa·s, and it has a natural blue semi-transparent cream appearance.

[0042] The second aspect of this embodiment provides a method for preparing a high-viscosity cream-type skin care product, the specific steps of which are as follows: The aqueous and non-aqueous phases were heated to 80°C respectively, mixed and pre-emulsified to obtain a crude emulsion. After cooling to 50°C, the emulsion was passed into a microfluidic homogenizer and homogenized three times under a pressure of 15000psi (approximately 103.42MPa). No post-thickening or maturation was required, and the product was directly discharged to obtain a high-viscosity cream-type skin care product.

[0043] The viscosity of the crude emulsion is 93420 mPa·s; The viscosity of the high-viscosity cream-type skin care product is 82500 mPa·s, and it has a bluish cream-like appearance.

[0044] Comparative Example 1 The difference from Example 1 is that the formula is the same, but the preparation method is different. The preparation method of this comparative example is as follows: After mixing and emulsifying the aqueous and non-aqueous phases, the mixture is homogenized for 3 minutes using a traditional homogenization method, then neutralized and thickened, and matured for 6 hours to obtain the finished product.

[0045] Performance: The finished product has a viscosity of 61600 mPa·s and a milky white creamy texture.

[0046] Comparative Example 2 The difference from Example 1 is that cetearyl alcohol, which was used in Example 1, is not added; the rest of the formulation and process are the same as in Example 1.

[0047] Performance: The finished product has a viscosity of 2176 mPa·s and presents as a bluish, thin emulsion.

[0048] Comparative Example 3 The difference from Example 1 is that the acrylic (ester) / C10-30 alkanol acrylate crosslinking polymer in Example 1 is replaced by an equal amount of the conventional thickener carbomer (purchased from Guangzhou Rongdao Chemical Co., Ltd., model CARBOPOL® 981Polymer). The amount added, the rest of the formulation, and the process are completely consistent with Example 1.

[0049] Performance: The finished product has a viscosity of 1740 mPa·s and presents as a bluish, thin emulsion.

[0050] Comparative Example 4 The difference from Example 1 is that the nonionic emulsifier in Example 1 is replaced with the anionic emulsifier tris(lauryl ether-4) phosphate, and the amount added, the rest of the formulation and process are completely the same as in Example 1.

[0051] Performance: The finished product has a viscosity of 3376 mPa·s and presents as a bluish, thin emulsion.

[0052] Comparative Example 5 The difference from Example 1 is that cetearyl alcohol in Example 1 is replaced with hydrogenated coconut oil glycerides, while the amount added, the rest of the formula and process are completely the same as in Example 1.

[0053] Performance: The finished product has a viscosity of 2058 mPa·s and presents as a bluish, thin emulsion.

[0054] Comparative Example 6 The difference from Example 1 is that the thickening component in Example 1 is adjusted to 0.8g and the cetearyl alcohol is adjusted to 0.6g, that is, the ratio of thickening component: emulsifier: fatty alcohol = 0.8: 1.2: 0.6 = 1: 1.5: 0.75, which does not meet the core ratio requirement. The rest of the formula and process are the same as in Example 1.

[0055] Performance: The finished product has a viscosity of 3320 mPa·s and presents as a bluish, thin emulsion.

[0056] Viscosity test of material Viscosity was measured using a Brookfield rotational viscometer at a test temperature of 25℃±1℃. Samples were allowed to stand at 25℃ for 24 hours after preparation before testing. Systematic testing of the viscosities of the samples from the examples and comparative examples showed that the viscosities of Examples 1 and 2 met the requirements for high-viscosity creams; while the viscosities of the finished products from Comparative Example 2 (lacking fatty alcohol), Comparative Example 3 (replaced with the conventional thickener Carbomer 981), Comparative Example 4 (replaced with an anionic emulsifier), Comparative Example 5 (replaced with other solid oils), and Comparative Example 6 (ratio not meeting requirements) were all below 5000 mPa·s, exhibiting a thin emulsion state. This indicates that only when the formulation system has a specific combination of thickener, emulsifier, and fatty alcohol in a specific ratio can it effectively offset the viscosity loss caused by the high-intensity shearing action of microjets, forming a stable high-viscosity cream system.

[0057] Stability test The high-viscosity formulations of Examples 1 and 2, and Comparative Example 1, were subjected to 15-day stability tests at -15°C, 25°C, 48°C, and -15~48°C, respectively. The stability comparison between Examples 1-2 and Comparative Example 1 is shown in the following figures. Figure 1 As shown in Table 1, the observation results are as follows.

[0058] Table 1: Stability performance under different conditions

[0059] Depend on Figure 1 As shown in Table 1, Examples 1 and 2 prepared using the microfluidic process did not exhibit any changes in texture, low-temperature crystallization, or high-temperature oil separation, while Comparative Example 1 showed significant changes in texture. This indicates that the creams and ointments prepared using the microfluidic process have excellent stability.

[0060] Skin feel test experiment A double-blind test was conducted on samples prepared in Example 1 and Comparative Example 1. A questionnaire was designed, and 30 participants were invited to rate the skin feel of the two products across dimensions such as appearance, refreshing sensation, absorption speed, moisturizing sensation, softness, and stickiness. The results were recorded and analyzed. The results are as follows: Figure 2 As shown in the comparison results of the skin feel of Example 1 and Comparative Example 1, it can be seen that Example 1, prepared using the microfluidic process, performs excellently in multiple dimensions such as appearance, texture, softness, smoothness, and absorption speed. Furthermore, it scores significantly lower in the stickiness dimension, indicating that the microfluidic process can effectively improve the skin feel of high-viscosity creams, enhancing the smoothness of application, absorption speed, and refreshing sensation, while reducing stickiness and discomfort. This result further verifies the technical advantages of the microfluidic process in optimizing the user experience of high-viscosity skincare products.
