The present invention relates to a hydrogel composition having a good anti-hydration effect prepared by using a gelling agent as a gelling agent and a molded article including the same.

Hydrogel is a material with high water content that can contain 20 to 90% of water and occupies a unique position in the fields related to medicine, pharmaceuticals and their high water content properties. Recently, application fields such as wound dressings, contact lenses, drug delivery media, implants, and wastewater treatment agents are also diversifying.

Applicant has prepared a hydrogel composition which can be applied to the field of skin care in Korean Patent Application No. 2003-56557 filed August 14, 2003. More specifically, the present invention relates to a temperature sensitive state change hydrogel composition and a method of manufacturing the same, which are changed into a fluid state by body temperature and which can be effectively applied to skin care. In particular, the composition is very excellent in applying as a skin mask as a substance that can be effectively used for skin beauty by transdermal delivery, from which the beauty agent is delivered from the hydrogel to the skin. There is no problem in applying this composition to a skin mask or the like, but it is unsuitable for use around the eyes because a little bit of water occurs.

Currently, ice packs are used to reduce eye fatigue, swelling, and pain after surgery due to long study, meeting, and driving. Ice packs are manufactured by inserting a material that can give a sense of cold or warmth in a synthetic resin bag, and indirectly receive cold or warmth of the inserted material through the pocket, and directly contact the insert with the skin around the eyes. Is missing. As a result, it can only exert a function of reducing eye fatigue through indirect contact, can not deliver the insert directly to the skin, there is a hassle to wash for repeated use, careless cleaning In the case of a bacterial infection around the eyes may also occur, there was a problem to carry and use.

In addition, eye sheets manufactured in Japan are currently commercially available. This eye sheet is used by impregnating the liquid in the nonwoven fabric, and it is not excellent in preventing the completion of water, and when it is used, the impregnated liquid can flow down into the eye, and the moisture evaporation rate is fast, so it can keep the cold air and deliver it very much. There is a short problem.

On the other hand, Korean Patent Publication No. 2000-33230 discloses an aqueous gel composition which is configured to contain a natural polymer such as iota carrageenan and has an anti-hydration function, but this composition is a fragrance that is not intended for application to the human body. And a gel adjuvant, such as cellulose and cellulose derivatives, were prepared for the purpose of being applied to the deodorant, in order to exert strength, elasticity and diuretic efficacy suitable for such use.

As a result, the gel surface has moisture, but it does not flow out properly, and it has high strength and elasticity enough to be applied to a beauty pack, so it can be used on all human parts including the eye area, and especially when used on the eye area. There is a need for a composition containing a natural polymer material that can deliver cold air without causing a phenomenon to relieve eye fatigue.

The present inventors, when using a mixture of iota carrageenan and locust bean gum in a predetermined amount as a gelling agent, it is possible to excellently prevent the completion of hydration even without adding a gel adjuvant such as a cellulose derivative, and is applied to all human parts including the eyes. It can be used to deliver functional cosmetic ingredients to the skin while recovering fatigue, swelling, etc. of the application site, and have a wound healing effect, easy to carry and short-term use. The present invention has been found to be able to produce a hydrogel composition that can be used in a molded article having a fatigue reduction effect.

An object of the present invention is to provide a hydrogel composition excellent in anti-hydration effect.

Another object of the present invention is to provide a hydrogel molded body applicable to all human parts, including around the eyes.

Still another object of the present invention is to provide a hydrogel molded article capable of delivering functional cosmetic ingredients while reducing fatigue at the application site.

In order to achieve the above object, the present invention is a hydrogel composition configured to contain a natural polymer material, 0.5 to 10% by weight of the natural polymer material with respect to the total weight of the composition, functional cosmetic ingredients 6 to impart skin cosmetic function 40% by weight, preservative 0.001 to 0.3% by weight and the balance water, wherein the natural polymer material is a two-component mixture of Iota Carrageenan and Locust Bean Gum (LBG) or the two components Kappa Carrageenan, Gelatin, Agar, Alginate, Chitosan, Chitosan Derivatives, Starch, Pullulan, Galactomannan, Glucomannan, Guar gum ), Pluronic, Algin, Gellanum, Xanthan gum and Pectin are added and mixed with one or two or more substances selected from the group consisting of It is a multicomponent mixture, and the functional cosmetic ingredient is characterized in that it is one or more substances having skin cosmetic functions including wrinkle improvement, skin whitening, sun protection, hydration, nutrition and skin elasticity.

In addition, the present invention is characterized in that the molded article having a hydrogel layer comprising the hydrogel composition.

Hereinafter, the present invention will be described in more detail.

The hydrogel composition of the present invention contains a natural polymer material, a functional cosmetic ingredient for imparting skin cosmetic function, a preservative and water as essential components.

The natural polymer material acts as a gelling agent to form a gel in the composition of the present invention and gives a feeling of cooling to the skin, but the variety thereof is various, but it should be particularly capable of preventing the completion of water while maintaining a proper moisture content. To this end, the present invention uses a two-component mixture of iota carrageenan and locust bean gum as a natural polymer, or kappa carrageenan, gelatin, agar, alginate, chitosan, chitosan derivatives, starch, pullulan, A multicomponent mixture is prepared by adding one or two or more substances selected from the group consisting of galactomannan, konjac mannan, guar gum, pluronic, algin, gellan gum, xanthan gum and pectin. Carrageenan is an algae extract belonging to the red algae, and can be classified into a Kappa type and an Iota type that form gels, and a Lambda type that does not form gels. And a mixture of locust bean gum is used as an essential component of the gelling agent. When Iota carrageenan is used alone, tissue is less dense than kappa carrageenan, so it has elasticity but has a weak gel. However, synergistic effect can be obtained when mixed with locust bean gum, and the gel surface has moisture, but has excellent anti-hydration effect such that it does not flow out, and forms a gel having high strength and elasticity enough to be applied to a beauty pack. On the other hand, when kappa carrageenan and locust bean gum are mixed, this synergy does not occur, and thus a little bit of water is generated, and when the water enters the eye, it may cause eye pain or cause eye disease. The gel could not be applied to the eyes. In the present invention, when the natural polymer material is used in an amount of less than 0.5% by weight relative to the total weight of the gel composition, the elasticity and strength of the gel composition may be weak, and when used in an amount of more than 10% by weight, the elasticity and Problems with too strong strength may occur, so it is preferable to use it in an amount of 0.5 to 10% by weight. More preferably in an amount of 1 to 5% by weight. In addition, the natural polymer of the present invention is most preferably a mixture containing iota carrageenan, locust bean gum and konjac mannan.

Such functional cosmetic ingredients have a negligible effect when used in an amount of less than 6% by weight based on the total weight of the hydrogel composition, and when used in an amount of more than 40% by weight, solubility may be reduced, and thus 6 to 40% by weight. Preferably used in amounts of%.

The preservative may be used without limitation so long as it is a substance used for preservative purposes, for example, 1 selected from the group consisting of paraoxy aromatic acid esters, phenoxyethanol, imidazolidinyl urea, phenonib, and various natural preservatives. Species or two or more compounds may be used. If the preservative is used in an amount of less than 0.001% by weight based on the total weight of the hydrogel composition, there is a problem in that the gel composition cannot be preserved for a long time, and when used in an amount of more than 0.3% by weight, there is a problem that may be harmful to the human body. Therefore, it is preferably used in an amount of 0.001 to 0.3% by weight.

Water is composed as the main component of the hydrogel composition of the present invention to occupy the remaining amount excluding the natural polymer material, functional cosmetic ingredient and preservatives.

The hydrogel composition of the present invention may further comprise a conventional natural biological material in addition to the main component.
