Description

Technical Field

[0001] This application relates to the field of cosmetic technology, specifically a process for producing a stepped temperature-controlled filling skincare cream and its application. Background Technology

[0002] In today's cosmetics industry, multifunctional products that combine skincare and makeup functions have become the mainstream trend, with creams and lotions, represented by "luxury creams," being particularly prominent. These products have complex formulations that typically need to address multiple objectives: on the one hand, they require high proportions of powdery ingredients such as titanium dioxide and pearl powder to provide an immediate brightening effect and a "bare-faced" look by concealing minor imperfections; on the other hand, to achieve skincare benefits, their formulas often incorporate rare plant extracts and heat-sensitive bioactive ingredients such as ceramides to achieve anti-aging, barrier repair, and long-lasting moisturizing effects. This complex system of "powder-oil-active ingredients" places extremely high demands on the product's manufacturing process.

[0003] Currently, the mainstream process for preparing such creams in the industry still mainly uses the traditional high-temperature emulsification method. This process usually involves directly adding heat-sensitive active ingredients under high temperature or using a simple natural cooling method. The former easily leads to the decomposition and inactivation of active ingredients such as vitamins, ceramides, and plant extracts due to prolonged heating, seriously affecting the final efficacy of the product; the latter, due to slow cooling and uncontrollable crystal formation, makes it difficult to build a stable product structure, resulting in problems such as sedimentation, precipitation, and stratification of high-content powders and oils during storage, affecting the product's appearance and stability. In addition, in order to maintain the stability of the system, traditional formulas often rely on a large amount of emulsifiers and thickeners, which brings the negative effects of a heavy, sticky feel and difficulty in spreading evenly, which runs counter to the high-quality experience that consumers seek: "lightweight, breathable, and melts into water upon application."

[0004] Based on the above statements, this application provides a process for manufacturing a stepped temperature-controlled filling skin care cream and its application. Summary of the Invention

[0005] To address the shortcomings of traditional high-temperature emulsification processes, such as easy deactivation of active ingredients, poor product system stability, and a thick, sticky texture, this application provides a process for producing a stepped temperature-controlled filling skincare cream and its application.

[0006] Firstly, this application provides a process for manufacturing a stepped temperature-controlled filling skincare cream, employing the following technical solution: The process for producing a temperature-controlled, stepped-filling skincare cream includes the following steps: S1. Raw material pretreatment: Mix and grind phase A raw material evenly; heat phase B raw material and phase C raw material separately, homogenize for 3-5 minutes, and keep warm for later use; S2. Emulsification: Mix the pretreated phase A raw material with the phase B raw material and homogenize for 2-3 minutes, then add the pretreated phase C raw material and mix and homogenize for 2-3 minutes to form the basic emulsion A. S3. Low-temperature addition: After cooling the base emulsion A, add the raw material of phase D, mix and homogenize for 3-5 minutes to form base emulsion B; S4. Freeze-freeze: Freeze the base emulsion B and then restore it to room temperature to obtain the stepped temperature-controlled filling skin care cream.

[0007] Preferably, the A-phase raw material, by total weight percentage, comprises: 1-3% colorant 1, 2-4% colorant 2, 0.01-0.1% colorant 3, 0.001-0.01% colorant 4, 0.01-0.1% pearl powder, 0.1-0.5% quaternary ammonium salt-18 bentonite, and 5-8% ethylhexyl palmitate; Phase B raw materials include: 1-3% methyl glucosesquistearate, 5-8% polydimethylsiloxane, 1-3% isohexadecane, 1-3% isopropyl myristate, 0.1-1% glyceryl stearate, 0.5-1% hydroxystearic acid, 2-4% cetearyl alcohol, and 10-15% petrolatum; Phase C raw materials include: 30-40% Rosa damascena flower water, 5-7% glycerin, 0.1-1% betaine, 1-3% butylene glycol, 0.001-0.01% sodium hyaluronate, 0.1-1% preservative, 0.1-0.5% sodium polyacrylate grafted starch, 0.01-0.05% disodium EDTA and 0.1-0.5% xanthan gum; Phase D raw materials include: 0.01-0.1% Edelweiss extract, 3-6% Cordyceps mycelium fermentation broth, 0.5-1% Portulaca oleracea extract, 0.01-0.05% flavoring, 0.01-0.2% ceramide NP, 0.1-0.5% panthenol, 0.05-0.2% kava extract, and 0.05-0.2% tocopheryl acetate.

[0008] Preferably, the colorant 1 in phase A raw material comprises titanium dioxide, aluminum hydroxide and stearic acid in a mass ratio of 80-85:7-12:8; Colorant 2 comprises titanium dioxide, polydimethylsiloxane, and water in a mass ratio of 90-94:2-6:4; Colorant 3 comprises CI 77492 and triethoxyoctylsilane in a mass ratio of 96-98:2-4; Colorant 4 comprises CI 77491 and triethoxyoctylsilane in a mass ratio of 96-98:2-4.

[0009] Preferably, the preservative in the C-phase raw material comprises phenoxyethanol and ethylhexylglycerin in a mass ratio of 85-95:5-15.

[0010] Preferably, the Edelweiss extract in phase D comprises butylene glycol, water, and Edelweiss flower / leaf extract in a mass ratio of 66-68:30:2-4. The Cordyceps mycelium fermentation broth contains Cordyceps sinensis extract, 1,2-hexanediol, p-hydroxyacetophenone, and butylene glycol in a mass ratio of 97-98:0.6-1.6:0.4:1. The purslane extract comprises purslane extract and butylene glycol in a mass ratio of 45-50:50-55; The kava pepper extract comprises water, butylene glycol, and kava pepper leaf / root / stem extract in a mass ratio of 54-55:44-45:1.

[0011] Preferably, in step S1, both phase B and phase C raw materials are heated to a temperature of 80-85°C.

[0012] Preferably, in step S3, the temperature is reduced to 50-60°C.

[0013] Preferably, the freezing temperature in step S4 is -20°C to -15°C, and the ambient temperature is 25-35°C.

[0014] Secondly, this application provides the application of the skin care cream prepared by the process of producing the stepped temperature controlled filling skin care cream in the preparation of cosmetics for immediate brightening, long-lasting moisturizing and anti-aging.

[0015] In summary, this application has the following beneficial effects: 1. The activity and efficacy of heat-sensitive active ingredients are protected to the greatest extent. By adopting a "step-down cooling" method and adding all heat-sensitive active ingredients (such as ceramides, plant extracts, etc.) at a low temperature stage of 50-60℃, this application effectively avoids the degradation and inactivation problems of these active ingredients caused by prolonged heating in traditional high-temperature emulsification processes, ensuring that the core effects of long-term anti-aging and repair claimed by the product are achieved.

[0016] 2. A unique and stable "tofu-like" texture and three-dimensional network structure were successfully constructed. Through the key step of "freezing and setting," the components formed a large number of tiny, irregular crystals, which cross-linked with high-molecular polymers such as sodium polyacrylate grafted starch, constructing a stable three-dimensional network structure. This structure not only gives the product its distinctive appearance, but more importantly, it can stably "lock" the oil phase, water phase, and high-content powder particles (such as titanium dioxide and pearl powder) within the network for a long period of time, fundamentally solving the problems of sedimentation, oil separation, and stratification during product storage, and exhibiting excellent heat resistance, cold resistance, and thermal cycling stability.

[0017] 3. Achieves a "water-like" skin feel. The three-dimensional network structure formed by the aforementioned flash freezing possesses excellent thixotropic properties. The cream remains stable when stationary, but once applied and subjected to shear force, the network structure instantly disintegrates, and the viscosity drops sharply, achieving an instant transformation from a thick cream to a light liquid. This shear-thinning effect, combined with the released lightweight oils and silicone oils, delivers an exceptionally silky, moisturizing, and delicate application experience, completely eliminating the stickiness and heaviness commonly found in traditional luxury creams.

[0018] 4. Synergistically combining immediate brightening and long-lasting skincare benefits. The unique structure of this application successfully integrates the immediate brightening and corrective effects of titanium dioxide and pearl powder with the long-lasting nourishing and repairing effects of active ingredients such as cordyceps and edelweiss. The stable system ensures that the corrective ingredients do not settle, while the preservation of their activity guarantees the longevity of the skincare effects, meeting consumers' dual needs for a natural, bare-faced look and deep skincare.

[0019] 5. The process design is precise and suitable for large-scale industrial production. The process steps of this invention are clear, and the key process parameters (such as temperature and time) are clearly defined and controllable. It solves the technical problems of uneven product texture and poor stability caused by uncontrollable cooling rate in traditional processes. It has good repeatability and scalability, and is very suitable for large-scale industrial production and filling. Attached Figure Description

Adding active ingredients and discharging: Cool the emulsion to below 40°C, add hydrolyzed placental (sheep) extract, stir well, and let stand at room temperature to obtain the luxury cream provided in Example 2 of the commercially available product.

[0034] Stability test To evaluate the stability of the products, the following accelerated stability tests were conducted on the products of Examples 3-7, Comparative Examples 1-3, and Commercially Available Effective Examples 1-2 of this application: Cold resistance test: Store the sample in an environment of -15℃ and observe its stability; Heat resistance test: Store the sample in an environment of 45℃ and observe its stability; Thermal cycling test: The sample was cycled between -15℃ and 45℃ environments every 3 days to observe its stability; Viscosity stability test: The viscosity of the sample was measured every seven days to examine how it changed over time; All tests were conducted over a three-month period. After the tests were completed, the appearance and morphology of the samples were observed to determine whether any abnormalities such as oil separation, stratification, or deterioration occurred. The specific test results are shown in Tables 3 and 4.

[0035] Table 3 Temperature stability test results Table 4 Viscosity stability test results (×10) 3 cP) Based on the test results in Tables 3 and 4, the skincare cream prepared in the embodiments of this application (especially Embodiment 5) exhibits significant advantages in terms of stability and structure retention. Regarding temperature stability, Embodiment 5 performed satisfactorily in heat resistance, cold resistance, and thermal cycling tests, without any abnormal phenomena such as oil separation or layering; while the comparative products and some commercially available products showed problems with oil separation or failure in cycling tests in different tests, indicating insufficient system stability. Regarding viscosity stability, the viscosity of Embodiments 3, 4, 6, and 7 remained highly stable throughout the test period, with the final viscosity maintained at 95 × 10⁻⁶. 3cP showed minimal change; however, the viscosity of Example 5 increased instead of decreasing, further demonstrating the enhanced continuity of its internal three-dimensional network structure over time, resulting in a more stable system. In contrast, the viscosity of commercially available products and other comparative examples all showed significant decreases, with the viscosity of Commercially Available Effect Example 2 ultimately decreasing by 31%, proving that its structure continuously deteriorated during storage and could not maintain its initial state for an extended period. In summary, the product structure constructed using the stepped temperature control and rapid freeze-setting process in this application exhibits significantly better long-term stability than commercially available products and comparative examples prepared using traditional processes.

[0036] Sensory experience evaluation To evaluate the specific user experience of the products, the products of Examples 3-7, Comparative Examples 1-3, and Commercially Available Effective Examples 1-2 were directly applied to the faces of female volunteers aged 18 to 45, and the skin-fitting and lightweight feel were evaluated respectively.

[0037] The specific method is as follows: Samples of each product were distributed to volunteers. Each volunteer used each product for seven consecutive days. At the same time point, after the same simple cleansing and skincare routine, sensory evaluations were conducted on each product before and after use. A 5-point scale was used, with 5 being the best experience, 4 the next best, and 1 the worst. The evaluation results are shown in Table 5. Figure 2 .

[0038] Table 5 Sensory Experience Evaluation Results (Score: 1-5 points) From Table 5 and Figure 2 As can be seen, the "Lady Cream" of Example 5 of this application received a score of no less than 4.0 from all volunteers, with 4 volunteers scoring above 4.5 and the highest score being 5.0, demonstrating excellent and consistent skin-feel and lightweight sensation. In contrast, most of the scores for commercially available Example 1 and Example 2 were below 4.0, with only a few volunteers scoring above 4.0; while the overall scores for Comparative Examples 1-3 were generally low and fluctuated significantly. These results fully demonstrate that the "Lady Cream" provided by this application is significantly superior to commercially available products and comparative examples in terms of skin-feel experience.

[0039] Moisturizing efficacy test To verify the moisturizing efficacy of the products, skin moisture content tests were conducted on the products of Examples 1-7, Comparative Examples 1-3, and Commercially Available Effect Examples 1-2 of this application.

[0040] The testing method is as follows: A CK MPA10 skin moisture analyzer was used. Healthy volunteers aged 18-50 were randomly divided into 10 groups of 5 people each. The testing area was the inner forearm of the subjects. For 3 days before the test, no cosmetics were used on the test area. On the day of the test, the inner forearms were cleaned and the test area was marked. The subjects sat quietly for more than 20 minutes in an environment of 25℃ and 55% relative humidity to stabilize their skin condition.

[0041] During the formal test, 3cm×3cm test areas were marked on the inner sides of both arms. One side was used for sample testing, and the other side served as a blank control. 2.0g of sample was weighed and evenly applied to the corresponding test area. After 20 minutes, the residual sample was removed. Subsequently, the skin moisture content of the area was measured at 30 minutes, 1 hour, and 2 hours. The results are shown in Table 6.

[0042] Table 6. Results of Moisturizing Efficacy Test (%) As shown in Table 6, all tested samples exhibited immediate moisturizing effects. Among them, Examples 3-5 demonstrated the best and longest-lasting moisturizing performance, with skin moisture content increasing by more than 41% after 2 hours of application, significantly better than commercially available products and comparative examples. In particular, Example 5 showed that the skin moisture content after 2 hours was almost identical to that after 30 minutes, demonstrating excellent sustained water-locking ability. This indicates that this application, through specific formulation and processes, achieves a long-lasting moisturizing effect significantly superior to conventional products.

[0043] The above specific embodiments are merely explanations of this application and are not intended to limit this application. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
