Description

Technical Field

[0001] The invention relates to the technical field of skin care products, and in particular to a method for preparing a nourishing, firming and anti-wrinkle eye mask. Background Art

[0002] Skin aging is usually manifested by decreased skin elasticity, more wrinkles, increased roughness, and decreased elasticity. As the physiological age gradually increases, external pressure and environmental factors such as ultraviolet radiation and environmental pollution affect the skin's metabolism, which gradually slows down and accelerates the aging of cells, resulting in the loss of collagen, elastin, and hyaluronic acid in the cells. Deep wrinkles, expression lines, and skin sagging on the skin surface will become more severe year by year, especially the skin around the eyes.

[0003] The anti-wrinkle ingredients added to existing anti-wrinkle and firming eye skin care products are mostly simply compounded, with a relatively simple mechanism of action, and cannot play a systematic role, resulting in mediocre anti-wrinkle and firming effects, and slow effects or only short-term anti-wrinkle effects. Summary of the invention

[0004] The purpose of the present invention is to solve at least one of the technical problems existing in the prior art and to provide a method for preparing a nourishing, firming and anti-wrinkle eye mask.

[0005] The technical solution of the present invention is as follows:

[0006] One aspect of the present invention provides a method for preparing a nourishing, firming and anti-wrinkle eye mask, comprising the following steps:

[0007] S1, adding immortal grass, witch hazel, and elm wood shavings into an ethanol aqueous solution, mixing and soaking, and then high-pressure homogenization for extraction, taking the filtrate, microfiltering, concentrating, and freeze-drying to obtain a witch hazel-elm wood shavings extract;

[0008] S2, heating purified water to 60-80° C., then adding the herbaceous vine-witch hazel-elm wood shavings extract, ethylbisiminomethylguaiacol manganese chloride, dipeptide diaminobutyryl benzylamide diacetate, active collagen, and peppermint oil into the purified water and mixing evenly to obtain a premix A;

[0009] S3, mixing the humectant, the chelating agent, the rheology modifier and the purified water, homogenizing and then keeping warm for a certain period of time to obtain a premix B;

[0010] S4, when the temperature of premix B drops to ≤55°C, add premix A and natural plant preservatives into premix B, and mix well to obtain an eye mask mixture;

[0011] S5. Put the eye mask mixture into the packaging material containing the membrane cloth and seal it to obtain the nourishing, firming and anti-wrinkle eye mask.

[0012] Live collagen, i.e. hydrolyzed collagen, is smaller than collagen and is more easily absorbed by the skin. It has the effects of moisturizing, anti-wrinkle, relieving dark circles around the eyes, and fading fine lines around the eyes. Ethylbisiminomethylguaiacol manganese chloride is an antioxidant that can protect cells in the human body and has the functions of firming the skin, reducing fine lines, and anti-oxidation. Dipeptide diaminobutyryl benzylamide diacetate is a synthetic peptide that simulates snake venom serum. It can block the nerve conduction of acetylcholine, make loose skin firmer and more elastic, and thus improve dynamic wrinkles. Peppermint oil is rich in menthol, menthol and other ingredients, which have the effects of moisturizing, soothing, soothing, anti-inflammatory and softening the skin. It can inhibit the secretion of oil on the skin surface, promote skin metabolism, and give the skin a cool feeling. The main component of immortal grass extract is glyceryl glucoside, which can protect the stability of cell membranes and cell structures. It has excellent water-locking ability similar to hyaluronic acid, and stimulates cell vitality from metabolism, anti-oxidation, and collagen synthesis. The soothing factor unique to witch hazel has excellent calming and soothing effects. It can gently soothe sensitive skin and balance metabolism. It can soothe irritated skin and effectively help skin regeneration and heal wounds. It has a good improvement effect on eczema, sunburn, and chapped skin. North American witch hazel flower water can regulate the skin's balance and oil secretion from the inside out. It has astringent and antibacterial effects. It can quickly penetrate the skin, significantly tighten large pores, and prevent the formation of blackheads and acne. Elm shavings extract is a natural glycoprotein ingredient extracted from plants. It has excellent moisturizing and antibacterial effects, high safety and stability. It contains a variety of similar structures, which allows it to work from multiple angles and multiple ways to moisturize, tighten, and reduce fine lines.

[0013] The eye mask provided by the present invention has mild ingredients, high safety, no irritation to the skin, slow release with a cool skin feeling, and good stability; it adopts a reasonable compound of multiple functional ingredients, has the effects of soothing and moisturizing, firming and anti-wrinkle, anti-allergic and anti-inflammatory, fading eye fine lines, and relieving eye dark circles, and the effect is long-lasting. The undead grass, witch hazel, and elm shavings are mixed for extraction, which simplifies the extraction process and shortens the extraction time. The extraction operation is carried out by pre-immersion and high-pressure homogenization, and the comprehensive effects of pressure loss, expansion, shearing and high-speed collision of the suspension under high pressure conditions in the process of limiting the flow gap are utilized, which greatly accelerates the penetration and diffusion of soluble substances, shortens the extraction time, has high extraction efficiency, and has a high content of functional ingredients. The microfiltration technology is adopted, which can not only effectively filter out several extraction raw materials such as undead grass, witch hazel, and elm shavings, but also remove other insoluble substances in the filtrate, reduce the irritation to the skin, and the obtained filtrate has a relatively low molecular weight, and the ingredients are finer, which is easier to be absorbed and utilized by the skin. The freeze-drying process reduces the loss of heat-sensitive substances and easily oxidized components, increases the content of effective ingredients in the eye mask, and the effective ingredients can be stably maintained in the eye mask, thereby improving the stability of the eye mask's efficacy and the use effect.

Biofibers are skin-friendly and have the ability to cover deep into wrinkles and skin grooves. Therefore, they have a better lifting effect than ordinary cloth eye masks and can fit closely to the skin without falling off like ordinary eye masks. Biofibers can promote the production of collagen and elastin in the human body, repair damaged collagen and elastin fibers, activate cell activity, improve microcirculation, provide adequate oxygen supply to the eyes, smooth blood circulation in the eyes, and accelerate the discharge of metabolic products, thereby achieving the effect of repairing wrinkles, tightening, and fading dark circles.

[0096] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
