The technical problem to be solved by the invention is as follows: the water shield extract-containing essence has a good antioxidant effect on skin.
The second purpose of the invention is to provide a preparation method of the water shield extract-containing essence.
The technical scheme adopted by the invention for solving the technical problems is as follows:
an essence containing a water shield extract comprises the following components in percentage by mass: 5-15% of water shield extract, 2-5% of licorice extract, 1-2% of centella asiatica extract, 0.1-0.3% of turmeric extract, 1-5% of propylene glycol, 1-5% of butanediol, 0.1-0.5% of sodium lauryl sulfate, 0.1-0.5% of triethanolamine, 0.1-0.5% of hyaluronic acid, 0.2-1.0% of hydroxymethyl cellulose, 0.2-1.0% of glutathione, 0.05-0.3% of carbomer, 0.05-0.3% of allantoin, 0.05-0.3% of essence and the balance of deionized water.
The essence containing the water shield extract consists of the following components in percentage by mass: 5-15% of water shield extract, 2-5% of licorice extract, 1-2% of centella asiatica extract, 0.1-0.3% of turmeric extract, 1-5% of propylene glycol, 1-5% of butanediol, 0.1-0.5% of sodium lauryl sulfate, 0.1-0.5% of triethanolamine, 0.1-0.5% of hyaluronic acid, 0.2-1.0% of hydroxymethyl cellulose, 0.2-1.0% of glutathione, 0.05-0.3% of carbomer, 0.05-0.3% of allantoin, 0.05-0.3% of essence and 60-80% of deionized water.
The above essence containing water shield extract can be used as facial mask essence.
The water shield extract is water shield extract.
The preparation method of the water shield extract-containing essence comprises the following steps: weighing water shield extract, licorice extract, centella extract, turmeric extract, propylene glycol, butanediol, sodium lauryl sulfate, triethanolamine, hyaluronic acid, hydroxymethyl cellulose, glutathione, carbomer, allantoin and essence according to the weight percentage, and then uniformly mixing with deionized water to obtain the water shield.
The water shield extract is prepared by a preparation method comprising the following steps:
1) washing water shield with cold water, soaking for 8-10 hr, soaking with 60-70 deg.C water for 2-4 hr, pulverizing, soaking with ethanol for 6-8 hr to obtain crude extract;
2) centrifuging the crude extract in the step 1), collecting filtrate, and removing ethanol in the filtrate to obtain the product.
The mass fraction of the ethanol in the step 1) is 65-75%.
In the step 1), the volume ratio of ethanol to (the mixture of water shield and water) for soaking is 1: 1.
Preferably, the licorice extract is an alcohol-water extract of licorice, contains active substances such as glycyrrhizic acid, and is provided by Jiangsu Huibo Biotech limited.
Preferably, the centella asiatica extract contains active substances such as asiaticoside and madecassoside, and is provided by Jiangsu Huibobo Biotech limited.
Preferably, the turmeric extract is an alcohol-water extract of turmeric, contains active substances such as curcumin, and is provided by Jiangsu Huibo Biotech Co.
The water shield can inhibit activity of collagenase, and with increasing of collagenase in skin layers, the generation amount of collagen cannot keep up with enzymolysis speed, so that the collagen in the skin is reduced, and the skin is aged and loses vitality. The water shield can inhibit activity of collagenase, and can reduce collagen attenuation, thereby delaying aging. Researches find that the water shield extract can inhibit the activity of collagen enzyme, inhibit the hydrolysis of collagen and effectively prevent skin aging and vitality loss.
Thirdly, the water shield extract has the function of inhibiting hyaluronidase. The hyaluronidase is a specific lyase of hyaluronic acid, and the hyaluronic acid has good moisturizing effect and is a good transdermal enhancer. Therefore, the hyaluronic acid can not only keep the normal physiological function of the hyaluronic acid without being decomposed by inhibiting the activity of the hyaluronic acid, but also achieve the effects of resisting inflammation, allergy and tumor, and simultaneously supplement the hyaluronic acid and achieve better moisturizing effect.
Finally, the water shield extract also has the effect of inhibiting the activity of elastase. Elastase is not produced any more with age, and when the in vivo elastase is over-expressed, the elastase is promoted to excessively decompose the elastin, so that wrinkles are produced, the skin gradually loses elasticity, and the skin aging is accelerated. The water shield extract can effectively inhibit the activity of elastase, and has the effects of increasing skin elasticity, tightening skin, delaying aging and the like.
Glycyrrhrizae radix is dried root and rhizome of Glycyrrhiza uralensis Fisch of Leguminosae. Has the effects of invigorating spleen and replenishing qi, clearing away heat and toxic materials, eliminating phlegm and stopping cough, relieving spasm and pain, and harmonizing the medicines. Modern clinical pharmacology tests show that the licorice extract can inhibit the activity of tyrosinase and dopachrome tautomerase (TRP-2) and inhibit the polymerization of 5, 6-dihydroxyindole, so as to prevent the formation of melanin and achieve the effect of whitening skin.
Centella asiatica is a dry whole plant of centella asiatica of centella of Umbelliferae, has the effects of clearing heat, promoting diuresis, removing toxic substances and relieving swelling, and is clinically used for treating traumatic injury, skin diseases and the like. The main active molecules of centella asiatica include asiaticoside, asiatic acid and madecassoside, and can inhibit fibrous tissue hyperplasia, promote skin growth, and inhibit skin ulcer.
Turmeric, a perennial herb of the family zingiberaceae, has the effects of breaking blood, promoting the circulation of qi, stimulating the menstrual flow, relieving pain and the like. It is clinically used for treating chest and abdomen distending pain, shoulder and arm pain, irregular menstruation, amenorrhea, traumatic injury, etc. The main active molecules of the turmeric comprise curcumin, bisdemethoxycurcumin, demethoxycurcumin, dihydrocurcumin and the like, and the turmeric extract has the effects of maintaining beauty, keeping young, improving skin color and the like.
Hyaluronic acid, an acidic mucopolysaccharide compound, has various physiological effects in the human body, can regulate vascular wall permeability, promote wound healing, preserve moisture and water, diffuse water electrolyte, operate and the like. Hyaluronic acid is known as an ideal natural moisturizing factor, can improve the skin nutrient metabolism, make the skin tender and smooth, remove wrinkles, increase the elasticity and prevent aging, and is a good transdermal absorption enhancer while moisturizing.
The invention relates to a water shield extract-containing essence, which takes a water shield extract, a turmeric extract, a centella extract, a liquorice extract and hyaluronic acid as main components and assists auxiliary agents such as allantoin, glutathione and the like, wherein the glutathione is tripeptide containing gamma-amido bond and sulfhydryl, contains active sulfhydryl and can metabolize human cells to generate H2O2Reducing the glutathione into water, removing free radicals in human bodies, damaging cell membranes by the free radicals, promoting aging of the organisms, preventing the glutathione from peroxidation on human body cells, improving the oxidation resistance of the skin and enabling the skin to generate luster; allantoin is an amphoteric compound, can combine multiple substances to form double salt, has effects of protecting from light, sterilizing, relieving pain, resisting oxidation, keeping skin moisture, moistening and softening, enhancing skin care product hydrophilicity, absorbing water, and preventing water dispersion, and can promote tissueGrowth, cell metabolism, softening stratum corneum proteins; the essence disclosed by the invention can inhibit fibrous tissue hyperplasia and promote skin growth under the synergistic effect of the components, has the effect of inhibiting collagenase activity, and can further inhibit the activity of tyrosinase and dopachrome tautomerase (TRP-2) to further inhibit the polymerization of 5, 6-dihydroxyindole, so that the formation of melanin is prevented, and the effects of whitening skin, improving elasticity and firming skin, delaying skin aging and the like are further achieved. The essence disclosed by the invention has small irritation to skin and good affinity with skin, has the effects of whitening, elasticity and skin tightening of skin and skin aging delaying, and is healthy and environment-friendly.
