Description

[0001] The present invention relates to a liquid crystal emulsified organogel composition and a mask pack,

The present invention relates to a liquid crystal emulsifying organogel composition and a liquid crystal emulsified organogel mask pack containing the same.

The term organogel was first used to describe the specific concept of gelation of an oil in water microemulsion (Luisi et al., Colloid & Polymer Science, 1990, vol. 268, pp. 356-374). Recently, the concept is collectively referred to as an emulsified (emulsified) gel structure having a lamellar phase irrespective of the form of w / o or o / w. Such an organogel has a skin-like lamellar structure, , And the skin moisturizing ability can be maintained for a long time, and thus it has been widely applied to cosmetic compositions.

In recent years, cosmetics using liquid crystal emulsification have been increasing. Liquid crystal emulsification is a unique base that can encapsulate the active ingredients of skin cosmetics. Its components are similar to skin lipids, which compensate and improve the interstitial lipid layer to prevent evaporation of skin moisture. It is possible to protect the skin.

Up to now, there has been a vehicle called liposome as the most suitable structure for effectively penetrating the active ingredient into the skin in cosmetic composition. However, since the structure of liposomes is easily destroyed in creams and lotions containing a large amount of emulsifiers and additives, their application to the field of cosmetics is limited.

On the other hand, when the liquid crystal emulsification is applied, it has a lamellar structure similar to a skin lipid membrane and can function as a skin barrier and has an advantage of effectively delivering the active ingredient to the inside of the skin. Therefore, it is not only applicable to various cosmetic formulations, And vitamin C as well as to delay the rate of degradation.

Although these liquid crystal emulsification techniques are applied to various cosmetic products, there is no case applied to mask pack products. Unlike other cosmetic formulations, the mask pack moisturizes in a short time and is available as a function limited to moisturizing. However, according to recent consumer needs, mask packs with various functions are emerging. When applied to a mask pack, it is possible not only to improve the moisturizing property of the conventional mask pack product, but also to permeate the useful ingredients to the skin, as well as to improve the ease of gel mask and liquid crystal emulsifying technology It can be sold as an improved product.

When the liquid crystal emulsifier is added in an amount of less than 0.5% based on the total weight of the liquid crystal emulsified organogel composition for a mask pack, the oil may be separated without being mixed with the upper part of the water, and if it exceeds 10% There is a problem that the elasticity of the finally obtained liquid crystal emulsifying organogel drops.

The polyhydric alcohol which can be used in the present invention may be at least one selected from the group consisting of polyhydric alcohols such as glycerin, ethylene glycol, propylene glycol, dipropylene glycol, butylene glycol, propanediol and diglycerin.

The polyhydric alcohol may be contained in an amount of 0.5 to 35% by weight, more preferably 5 to 15% by weight based on the total weight of the liquid crystal emulsified organogel composition. When the amount of the gelling polymer is less than 0.5% by weight, dispersion of the gelling polymer tends to be difficult. When the amount of the gelling polymer is more than 35% by weight, the water content becomes relatively small. There is a tendency to increase.

The gelling polymer may be selected from the group consisting of galactomannan, glucomannan, guar gum, locust bean gum, pluronic, agar, algin, carrageenan, xanthan, gellan, gelatin, methylcellulose, cellulose, carboxymethylcellulose and hydroxyethylcellulose Natural sugars; At least one member selected from the group consisting of polyacrylates or salts thereof, hydrophilic gelling agents such as polymethacrylic acid, carboxyvinyl polymer, polyvinyl alcohol, polyacrylamide, polyethylene oxide, polyethyleneimine, polyvinylpyrrolidone / RTI >

The gelled polymer may be contained in an amount of 0.1 to 10% by weight, more preferably 0.5 to 5% by weight, based on the total weight of the liquid crystal emulsified organogel composition of the present invention. When the water-soluble polymer is added in an amount of less than 0.1% by weight based on the total weight of the liquid crystal emulsified organogel composition, it is possible to maintain the shape of the gel, but the gel has a high strength and low flexibility, The gel is stretched to make it difficult to maintain its shape, and it is difficult to manufacture due to its low elasticity.

In the present invention, a crosslinked matrix can be obtained by adding at least two gelling polymers, and the thus prepared matrix is preferable for maintaining the shape of a liquid crystal emulsified organogel when used as a skin cosmetic pack.

Most preferably from a group consisting of a branched polymer selected from the group consisting of galactomannan, glucomannan, guar gum, rocastine gum, and pluronic and agar, algin, carrageenan, xanthan, gellan, and gelatin It is preferable to mix at least one selected electrolyte polymer. The electrolytic gelling polymer serves to keep the composition of the present invention in a gel state at a normal temperature (about 20 ° C or less), preferably 0 to 30 ° C, That is, at about 30-40 DEG C, which is about 10-50 DEG C, preferably around body temperature, the gel of the present invention can be changed into a fluid state so as to be effectively applied to the skin.

At this time, it is preferable that the branched gelling polymer and the electrolytic gelling polymer are contained in an amount of 0.05-10 wt% and 0.05-5 wt%, respectively, based on the total weight of the composition, and if it is outside this range, Or when the temperature is raised, the phenomenon that the gel state changes into the fluid state may not occur.

Further, in the composition of the present invention, the gelled polymer may be mixed with at least one crosslinking agent selected from an acrylic polymer, a styrene-based copolymer and a mixture thereof, and preferable components as the crosslinking agent include, for example, sodium C10-30 Alkyl Acrylate Crosspolymer, Potassium Acrylates / C10-30 Alkyl Acrylate Crosspolymer, Acrylate / C10-30 Alkyl Acrylate Crosspolymer, Ethylene / Ethylene / Styrene Copolymer, Ammonium Acrylate / Methylstyrene / Styrene Copolymer, Acrylates / Ethylhexyl Acrylate / HEMA / Styrene Copolymer, Butylene / Ethylene / Styrene Copolymer Copolymers (Ammonium Acrylates / Methyl Styrene / Styrene Copolymer), styrene / VP Copolymer, and styrene / Can be given alone or in combination of two or more selected from the group consisting of methacrylate copolymer (Styrene / Acrylates Copolymer).

When the cross-linking agent is added, such a cross-linking agent not only improves the physical properties of the gel of the present invention, but also makes it possible to form a thin membrane, thereby improving sticking power and effectively retaining moisture And may further serve to provide a smooth feel to the liquid crystal emulsifying organogels of the present invention. The crosslinking agent may be added in an amount of 0.01 to 5% by weight based on the total weight of the liquid crystal emulsified organogel composition.

Further, the skin active ingredient which can be contained in the liquid crystal emulsifying organogel composition for a mask pack may be retinol, retinyl palmitate, retinyl acetate, retinoic acid, coenzyme quitin, elastin, collagen, hyaluronic acid, ceramide, collagen, caffeine, chitosan, At least one member selected from the group consisting of ascorbic acid, ascorbyl glucoside, alpha bissabolol, tocopherol, tocopherol acetate, arbutin, niacinamide, adenosine, retinol acetate, vitamins A, D, E, And preferably a mixture thereof can be used.

When a mask pack is prepared using the liquid crystal emulsified organo gel composition for a mask pack according to the present invention, the penetration permeation absorption rate of an oil soluble component such as tocopherol acetate, retinol acetate, vitamin A, D, E, coenzyme Q, Can be remarkably improved.

The natural extract may be selected from the group consisting of aloe, green tea, ginseng, red ginseng, vinegar, ginkgo leaf, propolis, mulberry leaf, silkworm, snail mucilage, kakaduplum, camucam, yashiyaki, squalane, caviar, broccoli, , Raspberry, raspberry, raspberry, mackerel, mackerel, mackerel, mulberry root, raspberry, carrot, caffeine, Hamamelis, Spirulina, salmon roe, It is preferably at least one selected from the group consisting of edelweiss, chamomile, lavender, peppermint, eucalyptus, lemon balm, oregano, tea tree, golden,

The skin active ingredient may be contained in an amount of 0.05 to 10% by weight, more preferably 2 to 5% by weight, based on the weight of the whole composition. If the skin active ingredient is contained in an amount of less than 0.1% by weight based on the weight of the whole composition, the effect of skin care is insignificant. If the skin active ingredient is contained in an amount exceeding 20% by weight, skin irritation and side effects may occur.

PH adjusters such as citric acid, potassium hydroxide and arginine, depending on the application and necessity; Preservatives such as parabens such as methylparaben, propylparaben and phenoxyethanol; Metal ion sequestrants such as EDTA 2Na; Other additives such as betaine, sorbitol, 1,2-hexanediol, moisturizers such as erythritol and the like may be added.

The other additives may be contained in an amount of 0.01 to 10% by weight, more preferably 0.05 to 5% by weight, based on the total weight of the liquid crystal emulsified organogel composition of the present invention.

Since the liquid crystal emulsifying organogels according to the present invention have a lamellar structure similar to skin, the skin affinity is improved, and thus the active ingredients of the skin can be easily and quickly transferred from the liquid crystalline emulsified organogels to the skin. In addition, the liquid crystal emulsifying organogels according to the present invention can adjust the oil level of each skin type relatively easily, thereby maintaining the water balance and facilitating delivery of the active ingredients of the skin, maintaining the skin moisture for a long time, .

Meanwhile, the mask pack using the liquid crystal emulsified organogel composition according to the present invention can be manufactured by the following process.

First, purified water and other additives are mixed and heated to about 70 to 85 캜 to dissolve the components. The skin active ingredient, moisturizing agent, etc. are added to the mixture and heated to a temperature of 70-80 ° C. At this time, a crosslinking agent may be added as needed. When the temperature is lower than 70 ° C, the components added to water are not completely dissolved. When the temperature is higher than 85 ° C, the stability of some additives and natural components may be lowered.

Separately, the oil and the liquid crystal emulsifier mixture heated to about 70 to 85 ° C were stirred in the mixed solution while stirring using a homomixer to prepare a liquid crystal emulsion base. Other additives such as preservatives may be further included if required. When the mixing temperature is lower than 70 ° C., the liquid phase and the oil phase are not easily mixed with each other, so that it is difficult to produce the liquid crystal emulsion base. When the temperature exceeds 85 ° C., There is a concern.

A dispersed gelling agent of a polyhydric alcohol such as an additional glycerin and butylene lysolecule in a stirred liquid crystal emulsion base is added and stirred to prepare a liquid crystal emulsified organogel.

The liquid crystal emulsifying organogel solution thus obtained may be coated on a support and then cooled at room temperature and molded into a desired shape to prepare a liquid crystal emulsified organogel mask pack.

The support may be nylon, rayon, nonwoven fabric or the like, and preferably a rayon mesh fabric may be used.

The liquid crystal emulsifying organogel mask pack can be formed into a desired shape suitable for a body part such as a face, an under eye, a ball, a chin, and a neck to obtain a final liquid crystal emulsifying organogel mask pack. Further, Both sides of the gel mask pack can be protected with a film.

The liquid crystal emulsified organogel composition coated on the support preferably has a thickness of 0.01 to 50 mm, and when the thickness is less than 0.01 mm, the gel may tear when attached to the skin, There is a problem in that they are not sufficiently transferred to the skin because the amount of the component is small, and when it exceeds 50 mm, the gel becomes excessively thick, thereby adversely affecting the skin.

Hereinafter, the present invention will be described more specifically by way of specific examples. The following examples are given for the purpose of helping to understand the present invention, but the scope of the present invention is not limited thereto.
