Description

Technical Field

[0001] The invention relates to the technical field of skin care products, in particular to a moisturizing and anti-aging skin care water and a preparation method thereof. Background Art

[0002] With the rapid development of modern science and technology and the improvement of people's living standards, people pay more attention to skin health, and the quality and efficacy of skin care products are also increasing. With the continuous upgrading of users' skin care concepts, people's demand for moisturizing and anti-aging is increasing. After cleansing, people usually use skin care water to replenish moisture and moisturize the skin to adjust the skin condition. However, the efficacy of skin care water on the current market is not enough to meet users' needs for moisturizing and anti-aging. Therefore, we propose a moisturizing and anti-aging skin care water and a preparation method thereof. Summary of the invention

[0003] The object of the present invention is to provide a moisturizing and anti-aging skin care water and a preparation method thereof. The skin care water has moisturizing and anti-aging effects.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical scheme: a moisturizing and anti-aging skin care water, comprising the following components: panthenol, vitamin C ethyl ether, magnesium ascorbyl phosphate, silicone-modified ascorbic acid, soluble proteoglycan, hydrolyzed collagen, sodium alginate, palmitoyl pentapeptide-4, tocopherol, lecithin, ferulic acid, theanine, adenosine, rice bran oil, propylene glycol, glycerin, humectant, thickener, emollient, viscosity controller, surfactant, pH regulator, adhesive, chelating agent and water.

[0005] Further, the skin care water includes the following mass components: 0.1-1.0% panthenol, 0.1-1.0% vitamin C ethyl ether, 0.05-0.20% ascorbic acid phosphate, 0.01-0.07% silicone-modified ascorbic acid, 0.01-0.10% soluble proteoglycan, 0.05-0.20% hydrolyzed collagen, 0.1-0.5% sodium alginate, 0.01-0.05% palmitoyl pentapeptide-4, 0.02-0.10% tocopherol, 0.1-1.0% ferulic acid, 0.5-2.0% lecithin, 0.01-0.03% theanine, 0.1-1.5% adenosine, 1.0-2.0% rice bran oil, 1-3% propylene glycol, 1-5% glycerin, 0.5-2.0% humectant, 0.1-0.8% thickener, 0.08-0.20% emollient, 0.1-1.0% viscosity controller, 0.1-2.0% surfactant, 0.1-1.0% pH adjuster, 1-3% adhesive, 0.01-0.10% chelating agent, and the balance is water.

[0006] Furthermore, the moisturizing agent is a mixture of one or more of glyceryl ether-6, glyceryl ether-26, polyglutamic acid, diglycerol, 1,2-pentanediol, phosphatidylcholine, hydrogenated lecithin, and sodium lactate.

[0007] Furthermore, the emollient is a mixture of one or more of oleyl alcohol, ethyl oleate, and cholesterol.

[0008] Furthermore, the thickener is one of carbomer and xanthan gum or a mixture of the two.

[0009] Furthermore, the surfactant is a mixture of one or more of hydrogenated castor oil isostearate, disodium succinate, and polysorbate-20.

[0010] Further, the pH adjuster is one of succinic acid, lactic acid, citric acid, and sodium citrate;

[0011] The viscosity control agent is hydrogenated castor oil isostearate;

[0012] The chelating agent is disodium EDTA.

[0013] Furthermore, the pH of the skin care water is between 5.0 and 6.0.

[0014] In the above technical scheme, ascorbic acid is a well-known antioxidant and whitening ingredient, which has good anti-free radical, melanin reduction, and collagen growth promotion effects. It has good applications in anti-aging, moisturizing, brightening skin tone, and improving overall condition of the skin; but its stability is poor and it is not easily absorbed by the skin. Its derivative vitamin C ethyl ether is more stable in performance, and its amphiphilic properties make it easier to penetrate the stratum corneum into the dermis, achieving the effects of promoting collagen production, repairing cell activity, and giving skin elasticity. Ascorbic acid phosphate has higher stability and has the same efficacy, without any irritation to the skin; and the phosphatase present in the human body can convert ascorbic acid phosphate into ascorbic acid, which is further used by the human body. Silicone-modified ascorbic acid introduces silicone into the structure of ascorbic acid, which improves the stability of ascorbic acid. At the same time, because silicone has good skin lubrication and moisturizing effects, it can further improve the moisturizing effect of silicone-modified ascorbic acid on the skin, and has higher stability and biological activity. Panthenol has moisturizing and repairing effects. It can be used in moisturizing and antioxidant products to increase the hydration of the skin's stratum corneum, improve skin roughness, and soothe the skin.

[0015] Soluble proteoglycan is a glycoprotein soluble in water. As a skin conditioner, it has good moisturizing and anti-wrinkle effects. Hydrolyzed collagen can absorb and retain moisture, promote the formation of collagen, and has good moisturizing, repairing and anti-aging effects. Palmitoyl pentapeptide-4 is an antioxidant and moisturizing ingredient. Tocopherol (vitamin E) has the effect of resisting free radicals and delaying aging; combined with ascorbic acid derivatives, it has a better antioxidant effect. Theanine is used as a moisturizer and nutrient to enhance the activity of skin cells, promote the formation of collagen, and has a good effect on resisting cell apoptosis and promoting the healing of skin damage. The main role of adenosine in skin care water is moisturizing and anti-oxidation, and it can be used as a skin conditioner to improve skin elasticity. Rice bran oil promotes the production of cholesterol and ceramide, can enhance the softness of the skin, enhance the skin-friendly effect of skin care water, prevent skin moisture loss, and achieve the moisturizing and anti-aging effects of skin care water. Sodium alginate also has moisturizing, anti-oxidation, soothing and repairing effects. It can absorb water and moisturize, increase the water content on the skin surface, relieve dry skin and dehydration problems, reduce the damage of free radicals to the skin, and delay skin aging. Ferulic acid can inhibit active oxygen, scavenge free radicals, inhibit lipid peroxidation, and the activity of enzymes related to free radicals; it can also improve the stability of tocopherol, ascorbic acid and its derivatives in skin care water, strengthen its anti-aging effect, and improve the water feel of skin care.

[0016] Through the different moisturizing and anti-oxidation mechanisms of the above ingredients, the prepared skin care water can achieve its long-lasting moisturizing and anti-aging effects in the dermis and stratum corneum of the skin.

[0017] A method for preparing a moisturizing and anti-aging skin care water comprises the following steps:

[0018] Step 1, heat water to 75-85°C, add a chelating agent; cool to 40-50°C, add adenosine, vitamin C ethyl ether, magnesium ascorbyl phosphate, sodium alginate, and theanine, stir and mix; cool to 25-35°C, add soluble proteoglycan, palmitoyl pentapeptide-4, panthenol, hydrolyzed collagen, propylene glycol, glycerin, humectant, thickener, viscosity control agent, surfactant, and pH adjuster to obtain component A;

[0019] Step 2, mixing ferulic acid, organosilicon-modified ascorbic acid and lecithin in anhydrous ethanol, reacting at 35-42° C. for 60-150 minutes, and rotary evaporating to obtain a composite;

[0020] Tocopherol, rice bran oil, emollient and complex are stirred and mixed to obtain component B;

[0021] Step 3: Add component B to component A, stir, homogenize, and sterilize to obtain skin care water.

[0022] Furthermore, step 1 includes the following process: heating water to 75-85°C, adding a chelating agent, and stirring at a speed of 100-150 r / min for 15-25 minutes; cooling to 40-50°C, adding adenosine, vitamin C ethyl ether, magnesium ascorbyl phosphate, sodium alginate, and theanine, and stirring at a speed of 20-30 r / min for 5-20 minutes; cooling to 25-35°C, adding soluble proteoglycan, palmitoyl pentapeptide-4, panthenol, and hydrolyzed collagen, and stirring at a speed of 100-150 r / min for 20-40 minutes; adding propylene glycol, glycerin, humectant, thickener, viscosity controller, surfactant, and pH adjuster, and continuing stirring for 8-22 minutes to obtain component A.

[0023] Further, step 2 includes the following process:

[0024] Mix ascorbic acid and ethylene glycol dimethyl ether, under the protection of nitrogen atmosphere and away from light, heat to 48-55°C, add dimethylaminopolysiloxane, and react for 6-8h; filter, wash, and dry to obtain organosilicon-modified ascorbic acid;

[0025] Mix ferulic acid, organosilicon-modified ascorbic acid and lecithin in anhydrous ethanol, react at 35-42°C for 60-150 minutes, and perform rotary evaporation to obtain a composite;

[0026] The tocopherol, rice bran oil, emollient and complex are stirred and mixed to obtain component B.

[0027] Further, in step 2, the mass ratio of ascorbic acid to ethylene glycol dimethyl ether is (15-20):100;

[0028] The mass ratio of ascorbic acid to dimethylaminopolysiloxane is 1:(1.1-1.5).

[0029] Furthermore, in step 2, the ratio of ferulic acid to anhydrous ethanol is (18-20) g / 100 mL.

[0030] Furthermore, step 3 includes the following process: adding component B to component A, stirring at a speed of 30 to 40 r / min for 3 to 8 minutes, homogenizing at a speed of 2700 to 3200 r / min for 5 to 10 minutes, sterilizing, and obtaining skin care water.

[0031] In the above technical scheme, the component polysaccharides in the skin care water have non-covalent interactions with ferulic acid, forming a composite product that is difficult to dissociate at the use temperature, which is not conducive to its percutaneous absorption in vitro. Mixing ferulic acid with phosphocholine causes charge transfer between the two, and the resulting complex has more excellent stability, and helps the penetration of ferulic acid in the pH environment of the skin, thereby improving its bioavailability. Compounding organosilicon-modified ascorbic acid with ferulic acid and phosphocholine promotes the emulsification of the complex in the skin care water, which helps the coating of ferulic acid and its dispersion in the skin care water. Moreover, the PO in phosphocholine can also form hydrogen bonds with Si-OH produced by the hydrolysis of organosilicon-modified ascorbic acid, effectively preventing the combination of organosilicon with cells, while utilizing the moisturizing and softening ability of organosilicon, avoiding damage to cell membranes.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] The moisturizing and anti-aging skin care water and its preparation method described in the present application achieve the long-lasting moisturizing and anti-aging effects of the prepared skin care water in the dermis and stratum corneum of the skin by combining various moisturizing and anti-oxidation ingredients such as panthenol, vitamin C ethyl ether, magnesium ascorbyl phosphate, organosilicon-modified ascorbic acid, lecithin, and ferulic acid, and utilizing their different moisturizing and anti-oxidation mechanisms. In addition, by compounding ferulic acid with lecithin and organosilicon-modified ascorbic acid, the stability and permeability of ferulic acid are improved, and at the same time, the damage of organosilicon to the cell membrane can be avoided.

[0071] Experiment: Take the skin care water obtained in Examples 1-3 and Comparative Examples 1-3, prepare samples, test their properties respectively and record the test results:

[0072] Moisturizing performance test: 120 subjects with dry and dehydrated skin were selected and divided into 6 groups. The samples were used once in the morning and evening after cleaning the skin. After 30 days, the skin moisture content of the subjects after using the samples for 120 minutes was used as the performance index and the average value was taken;

[0073] Antioxidant performance test: Take 2 mL of the sample, add it to 2 mL of DPPH ethanol solution (0.1 mmol / L), place it at 25°C for 60 min, and detect the absorbance of the sample at 517 nm, which is recorded as A i ; At the same time, add 2mL of sample into 2mL of anhydrous ethanol and detect the absorbance, which is recorded as A j ; Take 2mL of anhydrous ethanol and add 2mL of DPPH ethanol solution, detect the blank absorbance, record it as A0, calculate the DPPH free radical scavenging rate = 1-(A i -A j ) / A0.

[0074] Transdermal absorption rate test: Franz diffusion cell was used, with pig dorsal and abdominal skin as the model, exclusive 450r / min, temperature 32.5℃, effective diffusion area 1.77cm2, receiving cell volume 10mL, and 2mL sampled after 24h to detect its transdermal performance.

[0075] Skin moisture content (%) Free radical scavenging rate (%) <![CDATA[Cumulative transdermal absorption amount (μg / cm 2 )]]> Example 1 27.0 95.7 24.6 Example 2 28.4 96.6 26.1 Example 3 27.6 96.1 25.4 Comparative Example 1 24.1 95.5 19.8 Comparative Example 2 22.8 93.6 18.0 Comparative Example 3 21.7 92.4 14.7

[0076] According to the data in the above table, we can clearly draw the following conclusions:

[0077] The skin care water obtained in Examples 1-3 is compared with the skin care water obtained in Comparative Examples 1-3. The test results show that:

[0078] Compared with the comparative example, the skin care water obtained in Examples 1-3 has higher skin water content, free radical scavenging rate and cumulative transdermal absorption data, which fully demonstrates that the present invention improves the moisturizing and anti-oxidation properties of the skin care water and makes it have better skin absorption capacity.

[0079] Compared with Example 2, the skin care water in Comparative Example 1 does not contain lecithin, and the ferulic acid is added in a different manner. The skin care water in Comparative Example 2 does not contain lecithin and silicone-modified ascorbic acid, and the ferulic acid is added in a different manner. In the skin care water in Comparative Example 3, vitamin C ethyl ether, ascorbic acid phosphate, and silicone-modified ascorbic acid are replaced with vitamin C.
