Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a cosmetic composition of a customized instant gel pack on skin,

The present invention relates to cosmetics for making instant gel packs on the skin by first and second separating application.

Hydrogels have been developed for a variety of cosmetics and medicines. However, they are especially effective for relieving skin tension, skin moisturizing, improving elasticity, reducing wrinkles, removing the waste of dirt and contaminants on the skin surface, , Extra sebum elimination, blood smoothing action, psychological stabilizing effect, nutritional action and acts to stabilize or protect heat damaged skin.

The hydrogel sheet may contain a moisturizing agent, an anti-inflammatory agent, an anti-inflammatory agent, an exfoliating agent, an amino acid, a vitamin, a whitening agent, a skin revitalizing agent, an inflammatory agent, a skin active ingredient, a fragrance, can do.

In particular, the sheet-like mask is used in the form of a hydrogel coated on a support such as a nonwoven fabric or a woven fabric. The alginate used in the present invention is ion-crosslinked with cations having a valence of 2 or more to form a gel to form a gel. 10-0633705 'discloses a method for producing a nonwoven fabric pack (PACK) using sodium alginate, and Korean Patent No. 10-1207556 provides a gel-type peel-off type pack using alginic acid and a curing agent thereof However, the present invention provides a composition comprising xanthan gum or hydroxyethylcellulose in the preparation 2, and particularly provides a composition for forming and applying the gel before use. More generally, alginic acid is prepared by adding water to a mixture of alginic acid and divalent ions in powder form, as in Korean Patent No. 10-0855823, and applying the paste to a desired site by making a paste having viscosity. There have been various studies to provide a composition for making a gel or a gel phase using alginic acid to apply to skin. However, a pack composition for applying an agent to the skin and spraying the agent to form an instant gel on the skin Not provided.

A pack product which forms a hydrogel and attaches to the skin has the following problems.

1) Adhesion decreases.

In order for the hydrogel to be shaped and attached to the face or the desired site while maintaining its shape, the thickness should be 2 mm to 5 mm or more. If the hydrogel is attached to the skin by stretching it like paper, the adherence is inevitably lowered.

2) You can not cover all the desired parts.

For example, a mask sheet gelled in a molding die or a patch is not a customized type of individual skin. For example, a mask pack attached to the face can not cover the wrinkled region depending on the perforation state of the eyes, There are many cases where the mask pack can not cover.

4) The activity is low.

When a mask pack of a hydrogel is attached, it is laid down and its movement is restricted.

According to the present invention, when a gel-type primary coating composition containing alginic acid or alginate and a mist-type secondary coating composition containing a divalent cation are sequentially applied on the skin, a gel is formed immediately on the surface, A thin gel was formed.

The present invention allows hydrogels to be formed on a desired skin, thereby enhancing adhesion and forming a hydrogel without restriction on a site much thinner than conventional hydrogels, so that the hydrogels can be freely activated even after formation of a mask pack. Immediate adhesion on the skin was formed and a thin gel was formed. This makes it possible to chew up the mask pack which has excellent adhesion and coverage, but which is free from the limitation of post-pack activity.

FIG. 1 shows a state in which an agent is applied on the surface and an agent is sprayed to form an instant gel.
Fig. 2 shows a gel formed at various sites.
FIG. 3 is a graph showing a table of results of activity test.

The present invention is a hydrogel composition comprising a primary coating composition containing alginic acid or an alginic acid salt, which is sequentially applied to the skin to form alginic acid gel, and a secondary coating composition containing two or more cations.

The primary coating composition is characterized in that 0.01 to 15.00% by weight of alginic acid or alginic acid salt is blended, and the secondary coating composition is formulated with 0.01 to 60.00% by weight of a salt of a divalent or higher cation. Also provided is a hydrogel comprising the composition.

According to the present invention, when a primary coating composition containing alginic acid or alginate and a secondary coating composition containing two or more cations are sequentially applied to the skin, a gel is formed immediately, the formed gel has strong binding force, There is a transparent effect.

The present invention provides a hydrogel having high adhesion, 2) covering all the desired sites, and 3) providing a hydrogel with good activity.

Hereinafter, the present invention will be described in detail.

Alginic acid is a natural product containing about 30 to 60% by weight of dry brown algae and is a water soluble straight chain polyuronic acid. Alginic acid is a polysaccharide block copolymer of D-mannuronic acid and L-glutaric acid and commercially available alginic acid is a metal salt of polyuronic acid. Alginic acid is a carboxyl group per unit of uronic acid and is dissociated into anion in aqueous solution. Alginic acid dissolved in water forms a gel by forming an egg-box ion-bridging bond, which is ion-crosslinked in a form similar to the shape of an egg pack, by incorporating two or more cations into the gluconic acid block of alginic acid in the position of the egg yolk .

The alginic acid or alginic acid salt used in the present invention is well known as a substance in which a gel is formed by ionic crosslinking with a divalent or higher cations. And may be selected from among calcium, magnesium, aluminum, barium, zinc, nickel, copper, lead, strontium, cobalt and manganese which can be used as divalent cations, Alginic acid gel is also formed.

When the content of the alginic acid or alginic acid salt is less than 0.01% by weight, the desired gel can not be formed or the alginic acid gel is very weakly formed, %, It is difficult to use because the viscosity is too high.

In addition, 1 second agent should be applied to the skin in order to obtain desired results.

Hereinafter, the present invention will be described in more detail by way of examples. It is to be understood by those skilled in the art that these embodiments are only illustrative examples for explaining the present invention and that the scope of the present invention is not limited to these embodiments. The compounding amount is expressed in% by weight.
