Description

Phase change cosmetic pack composition containing seawater {A PHASE CHANGE COSMETIC PACK COMPOSITION CONTAINING SEAWATER}

The present invention relates to a new type of cosmetic pack composition, which contains seawater and is eco-friendly and has excellent skin improvement activity.

A hydrogel is a material having a three-dimensional hydrophilic polymer network structure using purified water as a dispersion medium. It contains a large amount of moisture and exhibits flexibility like natural tissue, so it is used in wound dressings, contact lenses, pharmaceuticals, cosmetics, implants, and wastewater treatment agents. It is being researched and developed in several pharmaceutical, cosmetic and environmental industries, including

Recently, a pack using a hydrogel has been widely used in the cosmetic field.

Conventional mask packs have poor skin adhesion, and there is also a concern of excessive skin irritation due to the high concentration of cosmetic ingredients in contact with the skin at the beginning, but the hydrogel does not cause these problems, so the moisturizing and nutritional supply of the pack is improved. The development of a type of hydrogel mask pack is being actively carried out.

Hydrogel has a structure similar to the cell matrix of the human body, so it is inert, has excellent elasticity, and has excellent oxygen and nutrient permeability, so it shows excellent biocompatibility. , a cosmetic pack composition to which various skin beauty ingredients are applied using a soft touch with skin adhesion is being developed.

However, the conventional hydrogel has only a function of controlling so that the active ingredient contained in the hydrogel, which is a matrix, is gradually released toward the skin.

Controlling the delivery of the active ingredient to the skin while the hydrogel maintains the gel state takes a relatively long penetration time, and the hydrogel has a disadvantage in that the active ingredient can only be delivered to a limited portion in contact with the skin.

Therefore, in order to improve the penetration effect on the skin, a penetration enhancer was added to the hydrogel or a temperature-sensitive hydrogel was made and applied. was difficult to implement.

On the other hand, to overcome this, a phase change hydrogel using calcium chloride that reacts with sodium alginate to generate sodium alginate has been developed. There was no effect except for consumer interest due to the phase change.

Therefore, the present inventors have completed the present invention by newly proposing a cosmetic pack composition to which seawater is applied as a result of earnest efforts to develop a cosmetic pack composition of a new formulation having excellent skin improvement effects with eco-friendly properties.

One aspect of the present invention, a hydrosol comprising sodium alginate and a first active skin ingredient; And a curing agent comprising seawater (seawater); is provided a phase change cosmetic pack composition consisting of.

The cosmetic pack is applied to the face or a predetermined body part for skin beauty, and can be used in a way that is applied to the skin surface and removed after a certain period of time has elapsed.

The cosmetic pack composition may include various cosmetic ingredients for skin improvement, and the cosmetic ingredients may penetrate into the skin according to skin application.

The cosmetic pack composition may consist of the hydrosol and the curing agent, and after evenly spreading the fluid hydrosol on body parts such as the face, it may cause a phase change to a gel state by applying the curing agent thereon.

The cosmetic pack composition can be evenly applied to the skin in a fluid formulation of a hydrosol, as well as cause a phase change to a gel formulation after application, so it can retain both advantages as a liquid formulation and a gel formulation.

In particular, the cosmetic pack composition can significantly improve the skin penetration of the cosmetic component compared to the case of applying it in a conventional hydrogel formulation, and has a skin improvement effect by synergistic activity with the mineral component of seawater, which is the main component of the curing agent. can be maximized.

The hydrosol may include sodium alginate and a first skin active ingredient.

The sol is a fluid having colloidal particles dispersed therein. In the hydrosol, the dispersion medium may be water.

The hydrosol can be evenly applied to the skin in a viscous liquid state, and can be changed into a semi-solid gel formulation by the curing agent.

The sodium alginate (Sodium alginate) is a natural polymer flocculant, and sodium alginate is extracted from seaweed and has excellent biosafety.

The sodium alginate is widely used as a food additive to increase the adhesiveness and viscosity of food, promote emulsion stability, and improve the physical properties and feel of food. It is used as a base for etc.

Alginic acid of sodium alginate reacts with calcium chloride (CaCl ₂ ) to gelation into calcium alginate, and can be used as a peel-off type cosmetic pack composition.

However, the cosmetic pack composition of the present invention realizes eco-friendly properties and remarkably improves the skin improvement effect by replacing the conventional calcium chloride, which is not beneficial to the skin, with seawater containing abundant minerals or its concentrate.

The phase change cosmetic pack composition not only has excellent skin penetrating ability, but also has a synergistic activity with the mineral component of seawater, as compared to a cosmetic pack of a hydrogel formulation that introduces a skin cosmetic ingredient, so that the skin improvement activity can be significantly enhanced.

The hydrosol may include a first skin active ingredient.

The skin active ingredient is a substance capable of exhibiting various effects for skin improvement, such as skin whitening or moisturizing, and may include various functional ingredients that may be included in cosmetics.

The skin active ingredient improves affinity with the skin and serves to increase the absorption rate of functional ingredients that can effectively act on the skin. and the like, but is not limited thereto.

The active ingredients for the skin are retinol, retinyl palmitate, retinyl acetate, retinoic acid, coenzyme Q10, elastin, collagen, hyaluronic acid, ceramide, collagen, caffeine, chitosan, ascorbic acid, ascorbyl glucoside, alpha-bisabolol, tocopherol. , tocopherol acetate, arbutin, niacinamide, adenosine, retinol acetate, vitamins A, D, E, and one or more may be selected from the group consisting of natural extract xylitol, but is not limited thereto, and preferably a natural extract.

The "extract" means that the active ingredient contained in the extraction material is separated by contacting the solvent and the natural extraction material under specific conditions.

The natural extract may be extracted with one or more solvents selected from the group consisting of purified water, lower alcohols having 1 to 4 carbon atoms, acetone, ethyl acetate, butyl acetate, and 1,3-butylene glycol, and the alcohol is 60 to It may be ethanol at a concentration of 90% (v/v).

The active ingredient contained in the raw material may have a different extraction ratio depending on the polarity of the solvent, and since the ethanol has excellent selectivity in extracting physiologically active substances from natural raw materials, the optimal hair growth promoting effect may be realized by the ethanol extraction. can

The extract may also include an extract that has undergone a conventional purification process. For example, the extract is separated using an ultrafiltration membrane having a constant molecular weight cut-off value, and various purification methods additionally performed such as separation by various chromatography (those prepared for separation according to size, charge, hydrophobicity or affinity). It may include a fraction obtained through

In addition, since the extract is sufficient as long as it contains the active ingredient contained in the natural raw material, it can be obtained not only in the form of an extract obtained using a predetermined solvent, but also in the form of a crushed product or a pulverized product of the natural raw material.

The natural extracts are yellow lily, seaweed, old ginseng, licorice, aloe, green tea, ginseng, red ginseng, pearl, wood vinegar, pine needles, ginkgo leaf, propolis, mulberry leaf, silkworm, snail slime, kakadu plum, camu camu, yasai yaja, squalane , caviar, broccoli, blueberry, witch hazel, acerola, chlorella, mangosteen, guava, cornflower oil, carrot, caffeine, hamamelis, spirulina, salmon roe, Ecklonia cava, giant kelp, balm, machi Prefecture, green onion, agar agar, mulberry It can be selected from the group consisting of root, raspberry, raspberry, hibiscus, mosquito, edelweiss, chamomile, lavender, peppermint, eucalyptus, lemon balm, oregano, tea tree, gold, seaweed, sea buckthorn, and citron, but it can deliver an effective effect to the skin. It is not particularly limited as long as it is a cosmetic and nutritional component that can be used, and preferably, it may be one or more selected from the group consisting of yellow lily extract, seaweed extract, ginseng extract, green tea extract, and licorice extract.

The curing agent may include seawater, and the curing agent may be applied on the hydrosol.

The seawater refers to normal seawater, and typically contains about 35 g of salt in 1 kg of seawater, of which about 80% (v/v) may be made of sodium chloride.

The seawater may include various mineral components, and the present inventors implemented an excellent skin improvement effect with phase change characteristics by replacing the calcium chloride used for the gelation of sodium alginate with a seawater component.

The curing agent includes seawater as an active ingredient, and after applying the hydrosol to the skin, by applying the curing agent to the surface, sodium alginate can be effectively gelled.

The seawater may be lava seawater, preferably desalted lava seawater.

The above “lava seawater” is underground seawater that flows underground as seawater is naturally filtered by a volcanic bedrock layer with good permeability. is known

The lava seawater does not mix due to the density difference with freshwater groundwater, and exists below the freshwater layer.

In Jeju Island, since the 1980s, lava seawater has been used as breeding water for halibut farms by utilizing characteristics such as low temperature and cleanliness. is receiving a lot of attention.

Lava seawater distributed only in the eastern part of Jeju Island (Gujwa-eup, Seongsan-eup and Pyoseon-myeon) is clean and has a constant water temperature throughout the year. Although not described in detail in this document, it has already been known in the existing literature (Registration Patent No. 10-1402025 and many others).

In particular, vanadium contained in a trace amount in the lava seawater is known to have an action to stabilize insulin secretion, germanium is effective in promoting blood circulation, enhancing immunity, and anticancer action, and selenium inhibits oxidation of fat, antioxidant It has been reported to have an activity, anticancer, infertility, anti-aging, and improvement of cholesterol levels.

The lava seawater not only possesses abundant minerals, but also inhibits the activity of 5α-reductase, has excellent acne improvement activity, and shows antihistamine activity by showing degranulation inhibitory activity (beta-hexosaminidase (β-free inhibitory activity). When treated with fibroblasts, it exhibits a production promoting activity of type I collagen.

The lava seawater is very clean because it is naturally purified in the process of passing through the basalt layer, and unlike the deep sea water that is taken in from the deep sea, it is cost-effective because it can be taken from the land.

The “desalted lava seawater” is a product obtained by desalting lava seawater, and may be in a partially dehydrated (water removed) concentrated liquid or completely dehydrated powder form. The phase of the desalted lava seawater is not particularly limited, and a composition containing mineral components is sufficient.

The desalted lava seawater may be obtained by applying any technique known in the art, and flash evaporation method, seawater freezing method, reverse osmosis method, ion exchange resin method, electrodialysis method, etc. may be used, but is not limited thereto, It can be appropriately selected in consideration of the characteristics of the process.

Specifically, the reverse osmosis method is a method of removing salts using a reverse osmosis membrane, and the electrodialysis method may refer to a method of selectively lowering the concentration of sodium without changing the concentration of a necessary mineral.

Meanwhile, the curing agent may include a second skin active ingredient.

The cosmetic pack composition may be used by sequentially applying the hydrosol and the curing agent to the skin, and the skin improvement effect may be further enhanced by introducing a second active skin ingredient to the curing agent as well as the hydrosol.

By simultaneously introducing one or more active skin ingredients into the hydrosol and curing agent of the cosmetic pack composition, more excellent skin functionality can be realized.

The hydrosol may include at least one selected from the group consisting of a moisturizer, a fragrance, a preservative, an emulsifier, and a skin softener.

The moisturizer is not particularly limited as long as it is a conventional cosmetic moisturizer component for supplying moisture to the skin.

The moisturizing agent is a polyhydric alcohol such as butylene glycol, propylene glycol, pentylene glycol, hexylene glycol, polyethylene glycol; Glycerin, such as glycerol, diglycerol, and polyglycerol; and saccharides such as sorbitol multitol, sucrose, starch sugar, and racucitol, but is not limited thereto.

The fragrance is a fragrance-producing component, for example, peppermint oil, spearmint oil, menthol, etc. may be mixed and used, but is not limited thereto.

The preservative is to prevent spoilage by the action of microorganisms, methyl paraben, phenoxyethanol, capryl glycol, paraoxybenzoic acid alkyl ester, paraben, pentanediol, ethylhexyl glycerin, 1,2-hexanediol, The group consisting of caprylglycoltroporone, p-oxybenzoic acid ester, 3-trifluoromethyl-4,4'-dichlorocarbabanilide, and 2,4,4'-trichloro-2-hydroxydiphenyl ether One or more may be selected from, but is not limited thereto.

The emulsifier is a material added to stably maintain the resulting emulsion, and may be selected from the group consisting of sucrose-based compounds, lecithin-based compounds, and ceramide-based compounds, but is not limited thereto.

The skin emollient may be at least one selected from the group consisting of hydrocarbon-based oils, silicone-based oils, ester-based oils, and natural oils.

The hydrocarbon-based oil may be Mineral oil, Isododecane, or Squalane, and the silicone-based oil may be Dimethicone, Cyclopentasiloxane, or Trisiloxane, but is not limited thereto.

The ester-based oil may be Octyldodecyl Myristate, Diisostearyl Malate, or Isopropyl Myristate, and the natural oil may be Macadamia nut oil, Sunflower oil, or Olive oil, but is not limited thereto.
