Description

Cream coated hydrogel mask < RTI ID = 0.0 >

The present invention relates to a cream-coated hydrogel mask, and more particularly, to a multi-layer hydrogel mask having a thin cream layer coated on a hydrogel surface that is stably emulsified.

The hydrogel used in the conventional hydrogel mask is a hydrogel of a hydrophilic type, and contributes greatly to reinforce the skin moisturizing layer and promote normalization of the skin function by sufficiently supplying water lacking in the skin. However, such a conventional hydrophilic hydrogel mask lacks a balance between water and oil, and thus has problems of moisturizing and shortening the duration of skin.

It is an object of the present invention to provide a hydrogel mask having a multi-layer structure in which a cream layer is coated on an emulsion type opaque hydrogel mask layer.

In addition, the present invention is based on the fact that moisturizing and oil component of the cream touching the skin firstly improves the flexibility of the skin, and the hydrophilic component of the hydrogel secondarily increases the persistence of skin moisturization, The present invention also provides a hydrogel mask for use in a method of manufacturing a hydrogel mask.

In order to achieve the above object, the present invention provides a multi-layered structure in which a cream layer is coated on the surface of a hydrogel layer in which an oil component and an active ingredient are stably emulsified, and the cream layer is made of camellia oil, rosehip oil, evening primrose oil Mushroom extract and marine plant extract as an active ingredient and the cream layer is made of a high viscosity emulsion type product having a formulation viscosity value of 20,000 to 50,000 cps.

In addition, the present invention is a multi-layer structure in which a thin emulsion layer is coated on the surface of a hydrogel layer in which an oil component and an active ingredient are stably emulsified, and the emulsion layer is made of camellia oil, rosehip oil, evening primrose oil, mushroom extract, Wherein the emulsion layer comprises an emulsion type product having a low viscosity of 500 to 20,000 cps in viscosity of the formulation.

Wherein the cream layer or emulsion layer comprises from 0.01 to 5.00% by weight of the cream or emulsion with respect to the total composition of the hydrogel mask.

Wherein the hydrogel layer contains a lipophilic surfactant of glyceryl stearate sorbitan stearate sorbitan sesquioleate having properties similar to sebum (sebum).

Wherein the hydrogel layer comprises 0.05 to 5.00% by weight of a lipophilic surfactant relative to the total composition of the hydrogel mask.

The cream-coated hydrogel mask according to the present invention exhibits a synergistic effect between the moisturizing and oil component contained in the cream layer, the hydrophilic moisturizing and oil component contained in the hydrogel layer, and the lipophilic surfactant, so that the oil- Thereby enhancing the barrier function and minimizing the amount of percutaneous water loss.

1 is a conceptual view showing a state in which a cream layer is coated on the surface of an emulsion type hydrogel composition impregnated in a support according to an embodiment of the present invention.

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

The cream-coated hydrogel mask according to the present invention has a multilayer structure in which a cream layer or an emulsion layer is coated on an opaque hydrogel layer of an emulsification type in which an oil component and an active ingredient are stably emulsified by a lipophilic surfactant.

Thus, in order to prepare a cream coated hydrogel mask according to the present invention, an emulsion type hydrogel composition and a cream or emulsion coated on the hydrogel composition are required.

The cream according to the present invention is mainly used for supplying nutrition to the skin. The cream contains camellia oil, rosehip oil, evening primrose oil, mushroom extract and marine plant extract as active ingredients. The viscosity of the cream is 20,000 ~ And emulsion is mainly used for imparting flexibility to the skin, chemical composition is the same as the above cream, and emulsion type product having a viscosity of 500 to 20,000 cps and having a viscosity of 500 to 20,000 cps.

The cream-coated hydrogel mask according to the present invention contains a lipophilic surfactant such as glyceryl stearate, sorbitan stearate, sorbitan sesquioleate and the like having similar properties to sebum in the hydrogel layer, Is not used, the oil component and the effective component of the hydrogel layer are stabilized. However, when a mask is used, the active ingredient is separated from the hydrogel layer together with the oil component, and penetration into the skin is facilitated.

In this way, the cream-coated hydrogel mask according to the present invention improves the skin's flexibility by first moisturizing the cream and moisturizing the skin, while the hydrophilic component of the hydrogel secondarily increases the durability of skin moisturization, The oil / moisture protective film is firmly formed.

That is, the cream-coated hydrogel mask according to the present invention is a one-stop service type hydrogel mask for simultaneously supplying moisture and nutrition to the skin.

The cream-coated hydrogel mask according to the present invention exhibits a synergistic effect between the moisturizing and oil component contained in the cream layer, the hydrophilic moisturizing and oil component contained in the hydrogel layer, and the lipophilic surfactant, so that the oil- Thereby enhancing the barrier function and minimizing the transdermal water loss (TEWL)

The cream coating content of the cream-coated hydrogel mask according to the present invention is preferably 0.01 to 5.00% by weight based on the total composition of the hydrogel composition and the cream coated on the hydrogel composition.

The reason is that when the content of the hydrogel mask is less than 0.01% by weight, the coating amount of the cream layer is too small to improve the flexibility of the skin, and when the content exceeds 5.00% by weight, It falls.

Hereinafter, the present invention will be described more specifically with reference to Examples, but the present invention is not limited to these Examples.
