Description

Technical Field

[0001] The invention relates to the technical field of cosmetic preparation, in particular to a method for preparing a facial cream containing edelweiss ingredients. Background Art

[0002] Facial cream can lock in moisture on the skin's surface and reduce moisture evaporation, thereby achieving a deep moisturizing effect. Therefore, it is widely used in daily life. With the increasing requirements for skin care, traditional moisturizing creams can no longer meet the needs. Edelweiss is widely used in facial cream formulas due to its unique antioxidant, anti-aging and moisturizing properties.

[0003] However, the natural active ingredients of Edelweiss are easily affected by environmental factors such as temperature, light, and humidity, resulting in poor stability of the extract. The active ingredients are easily lost during use. In addition, the commonly used Edelweiss extracts are in the form of oil or suspension, which are difficult to disperse evenly in the emulsification system, affecting its efficacy and texture.

[0004] Therefore, in order to solve the above problems of active ingredient loss and poor texture, a method for preparing a facial cream containing Edelweiss ingredients can be designed. Summary of the invention

[0005] To overcome the problem of active ingredient loss and poor texture.

[0006] The technical solution of the present invention is: a method for preparing a facial cream containing edelweiss ingredients, comprising the following steps: Step 1: Weigh the required raw materials according to mass proportion, including 10-30 parts of oil phase, 15-20 parts of deionized water, 10-15 parts of aloe vera gel, 10-15 parts of hydrosol, 5-10 parts of natural birch sap, 10-15 parts of skin conditioner, 1-2 parts of moisturizer, 0.1-0.2 parts of pH adjuster, 0.1-0.3 parts of thickener, 0.05-0.1 parts of preservative and 20-30 parts of edelweiss extract; Step 2: Pour the oil phase into a clean emulsifying pot, set the speed to 15-45 rpm, and then homogenize for 1-5 minutes, then add the skin conditioner and moisturizer, continue stirring and heating to 80°C-85°C and keep warm for 20-30 minutes to obtain a mixture A; Step 3: Add the edelweiss extract to the ionic liquid nano solution, promote the full contact and embedding of the extract and the nano solution by mixing, ultrasonic action and other means, and then pour the embedded edelweiss extract, deionized water, aloe vera gel, hydrosol, natural birch juice, thickener and preservative into another emulsifying pot, set the target temperature and speed until it is completely dissolved; Step 4: Slowly pour the mixture A in step 2 into the emulsifying pot in step 3, set the speed, evacuate, and homogenize for 8 to 15 minutes; Step 5: Cool down with condensing water. When the temperature drops to 42℃~45℃, add pH adjuster, set the speed and vacuum, homogenize and emulsify for 1 minute, then adjust the speed to 15~45rpm and stir evenly; Step 6: Take samples for testing. After passing the test, fill and package them for storage.

[0007] Preferably, the oil phase is jojoba oil, multifloral nectar oil, sweet almond oil, olive oil, coconut oil, lanolin, squalane and mineral oil in a mass ratio of 0-30:0-30:0-30:0-30:0-30:0-30:0-30:0-30:0-30.

[0008] Preferably, the skin conditioning agent is any one or more combinations of ceramide, cholesterol, phytosphingosine and polyquaternium-10.

[0009] Preferably, the moisturizer includes glycerin, urea, hyaluronic acid and propylene glycol in a mass ratio of 2:1:1:0.5, the thickener is carbomer or xanthan gum, and the preservative is tea tree oil or rosemary extract.

[0010] Preferably, in step three, the target temperature is 65°C to 80°C and the rotation speed is 15 to 45 rpm.

[0011] Preferably, in step 4, the rotation speed is 2000 to 3000 rpm, and the vacuum degree is -0.2 to -0.5 MPa.

[0012] Preferably, in step five, the vacuum degree is -0.2 to -0.5 MPa and the rotation speed is 1000 to 2000 rpm.

[0013] Preferably, the testing items include physical and chemical properties, component analysis, microbiological indicators, sensory quality, safety and stability.

[0014] The beneficial effects of the present invention are as follows: the advanced preparation technology is cleverly utilized, and the active ingredients in Edelweiss are encapsulated in nanoparticles through nano-coating technology, which can protect its stability and bioavailability, extend the shelf life, and improve the efficacy. The problem that the natural active ingredients of Edelweiss are easily affected by environmental factors is overcome. The cream can effectively stabilize the active ingredients of Edelweiss, so that it can maintain its efficacy under high temperature, strong light, humidity and other environments. At the same time, the cream also ensures that the Edelweiss ingredients can be evenly dispersed in the emulsification system, which can ensure that it can exert its best efficacy without affecting the texture of the cream. The rich active ingredients in Edelweiss are effectively extracted and combined to prepare a cream product with fine texture, easy absorption, moisturizing, anti-wind drying and other effects.
