Description

Technical Field

[0001] This invention belongs to the field of cosmetic technology, specifically relating to a moisturizing and fragrant body lotion and its preparation method. Background Technology

[0002] With the improvement of living standards and the continuous upgrading of skincare concepts, body care has become a preferred option for most people's refined skincare. As a core product in the body care category, moisturizing body lotion, with its basic functions of improving dry skin and repairing the skin barrier, has become an essential daily care necessity for people of different ages and skin types. The density of sebaceous glands on the body is much lower than that on the face, resulting in less sebum secretion and easier loss of natural moisturizing factors. This makes the body skin more prone to problems such as dryness, roughness, and flaking. Especially in the dry and cold autumn and winter seasons, in enclosed environments with air conditioning / heating, or due to factors such as frequent cleaning, dry environment, aging, and irregular work and rest, the skin barrier is easily damaged, and dryness problems will be further aggravated. In severe cases, discomfort such as tightness, stinging, cracking, and itching may occur, and it may even develop into sensitive skin. Therefore, efficient, gentle, and long-lasting moisturizing care has become the core demand for body skin care.

[0003] CN118319795A discloses a body lotion composition and its preparation method. The composition comprises the following substances in weight percentages: 8-12% moisturizer, 0.1-0.3% thickener, 10-20% oil, 2-4% emulsifier, 0.01-0.3% pH adjuster, 0.2-0.8% preservative, 0.1-5% active ingredient, 0.2-2% fragrance, and the balance being water. The composition has moisturizing, nourishing, skin-smoothing, and radiance-enhancing effects.

[0004] CN116687776A discloses a highly moisturizing body lotion and its preparation method. The highly moisturizing body lotion provided by this application, through reasonable compounding, has a unique skin feel, strong moisturizing effect, is gentle and non-irritating, and effectively improves the skin feel. The cationic emulsifier used can mask unpleasant oily skin feel and bring a powder-like experience. The cationic emulsifier has wash-resistant properties on the skin surface, resulting in a smoother and longer-lasting moisturizing effect. The charge of the cationic emulsion can inhibit most microorganisms, thereby reducing the amount of preservatives needed, making the system more gentle and skin-friendly. Furthermore, the unique powdery smoothness of the cationic system provides a light and weightless feel, long-lasting moisturization, and better meets user needs. The preparation method provided by this application has a simple process flow, is easy to prepare, and can meet the needs of mass production.

[0005] Although existing moisturizing body lotions can meet basic moisturizing needs, with the differences in consumer skin types, the diversification of usage scenarios, and the upgrading of skin care needs, current products still have technical pain points such as single function, inconsistent formulas, and insufficient gentleness. Therefore, there is an urgent need to develop a product with a scientific formula, skin-friendly texture, long-lasting moisturizing effect, and gentle ingredients to meet the needs of applications.

[0014] Preferably, the emollient comprises any one or a combination of at least two of ethylhexyl palmitate, petrolatum, polydimethylsiloxane, polydimethylsiloxane alcohol, or squalane.

[0015] Preferably, the thickener comprises ammonium polyacrylamide dimethyl taurate and / or cetearyl alcohol.

[0016] Preferably, the emulsifier comprises any one or a combination of at least two of glyceryl stearate, PEG-100 stearate, cetearyl alcohol, cetearyl glucoside, or potassium cetyl phosphate.

[0028] Preferably, the vegetable oil is a combination of shea butter, sunflower seed oil, and peony seed oil.

[0029] As a preferred technical solution of the present invention, the plant oil is a combination of shea butter, sunflower seed oil, and peony seed oil, which can precisely fill the gaps in the stratum corneum, further slow down transepidermal water loss (TEWL), block the evaporation of moisture from within the skin, and exert a strong and long-lasting water-locking effect, solving the problem of simple moisturizing ingredients "replenishing quickly but evaporating quickly." Meanwhile, recombinant human type III collagen and recombinant human type IV collagen, as small molecule protein peptides, have good hydrophilicity and water-holding capacity. They can actively capture free moisture from the air to replenish the stratum corneum, quickly relieving skin tightness and dryness, and can also penetrate into the stratum corneum to replenish the skin's lost natural moisturizing factors, enhancing the stratum corneum's own water-holding capacity. The synergistic effect of these two components allows the product to further form a "hydration-moisturizing" closed loop, allowing the skin to maintain a healthy moisture content within the stratum corneum for a long time.

[0030] All the specific point values ​​within the above range can be selected, and will not be elaborated on here.

[0031] In a second aspect, the present invention provides a method for preparing a moisturizing and fragrant body lotion as described in the first aspect, the method comprising: (1) Heat the water, then add humectant, thickener and antioxidant, and homogenize to obtain an aqueous phase liquid; The emollient and emulsifier were heated and homogenized to obtain an oil phase liquid; (2) Mix the aqueous phase and the oil phase homogenize, cool down and add fragrance, stir evenly to obtain the moisturizing fragrance body lotion.

[0032] Preferably, in step (1), the aqueous phase liquid is prepared at a temperature of 80-90°C (e.g., 81°C, 83°C, 85°C, 87°C, or 89°C), and the homogenization is carried out by stirring at a speed of 1000-3500 rpm (e.g., 1500 rpm, 2000 rpm, 2500 rpm, or 3000 rpm) for a time of 5-30 min (e.g., 10 min, 15 min, 20 min, or 25 min).

[0033] Preferably, in step (1), the oil phase liquid is heated to 80-90℃ (e.g., 81℃, 83℃, 85℃, 87℃ or 89℃, etc.), and the homogenization is carried out by stirring. The stirring speed is 1000-3500 rpm (e.g., 1500 rpm, 2000 rpm, 2500 rpm or 3000 rpm, etc.), and the time is 5-30 min (e.g., 10 min, 15 min, 20 min or 25 min, etc.).

[0034] Preferably, the temperature reduction to 30-40℃ in step (2) can be, for example, 31℃, 33℃, 35℃, 37℃ or 39℃.

[0035] Preferably, step (2) further includes adding a skin conditioner after cooling down.

[0036] All the specific point values ​​within the above range can be selected, and will not be elaborated on here.

[0058] Test Example 1: Moisturizing Effect Test The products prepared in Examples 1-13 and Comparative Examples 1-5 were evaluated for their long-lasting moisturizing and skin-firming effects: Ninety participants aged 20-45 were randomly selected and divided into 18 groups of 5. The 18 groups of participants used the products prepared in Examples 1-13 and Comparative Examples 1-5, respectively, once every night in the same amount, for 30 days, during which time no other skin care products were used.

[0059] Skin hydration was measured using a Corneometer CM825 on days 0 and 30 to assess the skin hydration before and after lotion application. Measurements were taken three times on the same area, and the average value was recorded. Results are shown in Table 1.

[0060] Skin condition was tested on day 0 and day 30 using a Cutometer MPA580 skin elastometer. The test site was the cheekbone area. Measurements were taken three times on the same area, and the average value was recorded. The test parameter was R² (the ratio of skin rebound Ua without negative pressure to the maximum stretch Uf under negative pressure). The closer R² is to 1, the better the skin elasticity. The average change in R² = R² value on day 30 - R² value on day 0, and the average rate of change in R² = average change in R² / R² value on day 0. The specific skin elasticity test results are shown in Table 1.

[0061] Table 1 The test results show that the moisturizing fragrance body lotions in Examples 1-3 have excellent moisturizing effects, and long-term use can help strengthen and restore the skin's moisturizing state.

[0062] As can be seen from Examples 1 and 4-11, adding collagen and plant oils can further improve the moisturizing performance of the product, and the moisturizing effect of the product will be more significant when both are added at the same time. In addition, the choice of collagen and plant oil types has an impact on the moisturizing effect of the product. As can be seen from Examples 1 and 12-13, antioxidants can help improve the moisturizing performance of products, and the choice of their type will also affect the moisturizing effect of the product. As can be seen from the comparison between Example 1 and Comparative Examples 1-5, glycerol, 1,3-propanediol, glycerol polyether-26, 1,2-hexanediol and panthenol have a synergistic effect in moisturizing in this invention.

[0063] Test Example 2: Antioxidant Test Test subjects: Samples from Examples 1-3 and 12-13.

[0064] Test method: Take 1 g of product, add 2 mL of anhydrous ethanol, dissolve completely, then add 2 mL of 60 μmol / L DPPH solution and mix well. Let stand for 30 min, zero with anhydrous ethanol, and measure the absorbance at 517 nm as Ai; In the same way, take 2 mL of anhydrous ethanol solvent + 2 mL of DPPH solution, mix well and measure the absorbance as Ac; Take another 1 g of the composition matrix, dissolve it, add 2 mL of anhydrous ethanol, then add another 2 mL of anhydrous ethanol solvent, mix well and measure the absorbance as Aj.

[0065] Calculate its free radical scavenging rate using the following formula.

[0066] Clearance rate (%) = [1 - (Ai - Aj) / Ac] × 100% Where Aj represents the contribution of the sample itself to the absorbance; Ai represents the absorbance of the sample after the DPPH treatment; and Ac represents the absorption of DPPH itself at the measurement wavelength.

[0067] The higher the DPPH scavenging rate, the stronger the antioxidant capacity of the composition to scavenge free radicals. The results are shown in Table 2 (each sample was measured in parallel 5 times, and the data are presented as average values).

[0068] Table 2 As shown in Table 2, the DPPH free radical scavenging rate of Examples 1-3 was higher than that of Examples 12-13, indicating that the choice of antioxidant type will reduce the DPPH free radical scavenging effect.

[0069] Test Example 3: Safety Evaluation Experiment Safety assessment: The specific method was as follows: Forty volunteers aged 20-35 years (half male and half female) with no history of allergies were selected. Each subject used the samples prepared in Examples 1-3. After cleaning the subject's arm, the patch applicator containing the sample was applied to the selected location on the arm using non-irritating adhesive tape. After application, the patch was gently pressed with the fingers to ensure even application to the skin, and left for 24 hours. During these 24 hours, the subject kept the patch area dry and avoided strenuous exercise, scratching, and prolonged sun exposure. After 24 hours, the applicator was removed and marked. After 30 minutes, once the pressure marks disappeared, the applicator was evaluated under sufficient light.

[0070] The grading criteria for adverse skin reactions are shown in Table 3: Table 3 The results are shown in Table 4: Table 4 As shown in Table 4, all subjects had negative reactions, indicating that the product prepared according to the present invention has no adverse reactions on the human body and is highly safe.
