Description

[0001] The present invention relates to a cosmetic composition for removal of gommage type exholiating skin having low irritant,

The present invention relates to a cosmetic composition for removing high-mage type exfoliating skin, which is capable of forming foam stably without containing liquefied gas and minimizing irritation to the skin and effectively removing waste products and keratin in the skin.

In the skin, the stratum corneum consists of 10-20 layers of dead cells and intercellular quality, natural moisturizing factor (NMF) present in the outermost part of the skin. The stratum corneum plays an important role in protecting skin from external pollutants and preventing moisture loss of the skin.

In a healthy person, the turn-over cycle of the skin stratum corneum is about 4 weeks and after a certain period of time, the old stratum corneum is naturally peeled off and a new stratum corneum is formed. However, due to internal factors such as aging and external factors such as ultraviolet rays, the turnover cycle becomes long and unbalanced, the stratum corneum is old and stratified, the skin becomes dull, the skin tone becomes uneven, and the skin becomes angular Occurs. Therefore, it is necessary to continuously remove the stratum corneum within a certain period of time,

Conventional conventional skin exfoliating cosmetics are represented by two types.

Firstly, it is a cosmetic product for chemical exfoliation, which is obtained by chemically dissolving keratin using AHA (Alpha Hydroxy Acid), BHA (Beta-Hydroxy Acid), salicylic acid and plant extracts containing it, And the like, thereby removing the keratin skin.

Korean Patent Laid-Open Publication No. 2011-27308 discloses a cosmetic composition containing an apricot extract of Hunza region as an active ingredient to supply moisture to the skin, reduce keratin, increase skin moisture content and improve skin texture. Open No. 2011-78367 proposes a composition for external application for skin which is excellent in the effect of softening the keratin skin and promoting the exfoliation of the keratin skin by containing an extract of ginseng fruit having a unique composition and composition among the above-ground parts of ginseng as an active ingredient.

These chemical exfoliating cosmetics may have some degree of exfoliating effect when used for a certain period of time, but they have disadvantages of causing skin irritation and causing side effects by using chemically active substances having a very low pH.

In addition, as a physical cosmetic material for removing exfoliation, there is a type of formulation in which a cream or a gel type formulation is physically peeled off by using wax, scrub or exfoliation powder.

Korean Patent Laid-Open Publication No. 2010-64435 proposes an exfoliating cosmetic composition capable of removing keratin and waste materials by using sodium chloride particles and a surfactant as scrub preparations and then simply rinsing with water without using a separate cleaning process after use , Korean Patent Registration No. 10-1172114 discloses a method of using a natural grain powder as an exfoliating agent to perform physical exfoliation primarily by the powder, and at the same time, a whitening functional ingredient is absorbed easily and quickly into the skin, To provide a whitening effect within a short period of time with a whitening functional ingredient of a cosmetic composition for skin whitening.

Such a physical exfoliating cosmetic composition has no chemical side effects on skin than a chemical exfoliant. However, since the skin is forcibly peeled off with wax or scrubbing for the purpose of exfoliation of skin, Lt; / RTI >

In addition, all of the chemical and physical exfoliation cosmetic preparations are used to clean the skin by preventing stratification of the stratum corneum, which is the main cause of skin roughness, uneven skin tone, and skin keratinization, It has a problem that it has stimulation, physical stimulation or storage risk and prolonged use time.

Recently, formulations on foams using liquefied gases and metal containers have been proposed to overcome the disadvantages of these cosmetic and physical exfoliating cosmetics.

Korean Patent Registration No. 10-0570498 discloses a cosmetic composition which has a low viscosity and contains a film-forming resin having excellent sebum adsorption and exfoliation ability and an exfoliating powder as main constituents, It is mixed and emulsified in a metal container together with a liquefied gas to obtain a mixture, followed by spraying.

For the composition of the foam formulation presented above, exfoliation powder such as polyethylene, polypropylene, polymethylmethacrylate, methylcellulose, propylcellulose, nylon and silica is used for exfoliation, And it is still causing skin irritation, and liquefied gas has a risk of storage.

Korean Patent Publication No. 2011-27308 Korea Patent Publication No. 2011-78367 Korean Patent Publication No. 2010-64435 Korean Patent Registration No. 10-1172114 Korean Patent Registration No. 10-0570498

In order to solve the above problems, the inventors of the present invention have conducted various studies on a cosmetic composition in which foam is formed without using liquefied gas and keratin is easily removed and physical stimulation to the skin is reduced. As a result, A novel cosmetic composition capable of reducing irritation and controlling the exfoliation rate was developed in addition to the above effects.

Accordingly, it is an object of the present invention to provide a cosmetic composition for removing high molecular weight exfoliants which can form a foam without using a liquefied gas, easily remove keratin, reduce physical stimulation to the skin, and control keratin removal rate .

In order to achieve the above object, the present invention provides a cosmetic composition for removing high molecular weight exfoliated cornea comprising a resin for forming an acrylic copolymer film and an organic acid.

In the present invention, a cosmetic composition for removing high molecular weight exfoliants capable of forming a foam without using liquefied gas in the form of exfoliation foam using a pump container so as to reduce physical stimulation to the skin is proposed.

Specifically, the composition uses an acrylate copolymer as a film-forming resin and uses an organic acid to adjust the pH so that the composition containing the acrylate copolymer is in a specific range of pH.

The acrylate copolymer is a resin for forming a film, which is uniformly applied over the entire skin, so that waste matter and dead skin on the surface of the skin adhere. Conventionally, polyvinyl alcohol, polyvinyl pyrrolidone, silicon, or the like is used as a film forming resin. When these are used, it is necessary to form a foam only by using a separate liquefying gas and to add an additive to form horny gummage. In contrast, the acrylate copolymer according to the present invention can effectively form horny gummage by controlling the content with an organic acid, and can form a foam without a separate liquefied gas.

Preferably, the acrylate copolymer is a liquid phase and is typically an acrylate / C10-30 alkyl acrylate copolymer, an acrylate / C12-22 alkyl methacrylate copolymer (Acrylates / C12-22 Alkyl Methacrylate Copolymer (Acrylates / Beheneth-25 Methacrylate Copolymer), Acrylates / Ceteth-20 Methacrylate Copolymer, Hydroxyethyl Acrylate / Ceteth-20 Methacrylate Copolymer, Acrylate / dimethyl acrylate / sodium acryloyldimethyl taurate copolymer and ammonium acryloyldimethyltaurate / VP copolymer, polyacrylate crosspolymer-6, -6), an acrylate / vinyl pyrrolidone copolymer, an acrylate / dimethicone copolymer, an acrylate / Acrylate / dimethicone methacrylate copolymer, and a combination thereof, and preferably an acrylate / methacrylate copolymer is used.

The acrylate copolymer is chemically or electrostatically bound to water such as OH and hydrogen bonds when water is dispersed in water, thereby forming a thin film upon application to the skin. At this time, the addition of the organic acid weakens the bond, and the acrylate copolymer is aggregated by the external stimulus simply rubbing the skin to form a horny gummage.

The organic acid may be at least one selected from the group consisting of citric acid, malic acid, succinic acid, tartaric acid, and a combination thereof, preferably citric acid.

The cosmetic composition for exfoliation according to the present invention has a proper pH and suitably forms a stable foam without liquefied gas, and forms a horny gummage when rolling after skin application to reduce skin irritation. It limits.

Fig. 1 is a photograph showing the use of the composition of Example 1, wherein (a) is a foam-forming photograph and (b) shows the formation of horny gummage after application of the skin. Referring to FIG. 1, it can be seen that the cosmetic composition for exfoliation having the composition of the present invention forms a foam without liquefied gas, and kerosene marjue is formed due to rolling after skin application.

Specifically, the cosmetic composition for removing exfoliation comprises 10 to 20 wt%, preferably 12 to 17 wt%, and 1.5 to 3.0 wt% of an acrylate copolymer, preferably 1.7 to 3.0 wt% of an acrylate copolymer so as to satisfy 100 wt% 2.5% by weight, and water as the remainder. Such an exfoliating cosmetic composition maintains a pH of 3.5 to 5.0.

If the content of the acrylate copolymer is less than the above range, peeling of the horny material does not occur smoothly when the composition is rubbed after the application of the skin. On the other hand, if the content of the hyaluronic acid is above the above range, Is not formed.

If the content of the organic acid is less than the above range, a stable foam can not be formed and excessive rolling is required until the formation of keratin hyaluronate is difficult or becomes excessive, thereby deepening skin irritation. On the other hand, Is formed to prevent absorption of wastes or keratin in the skin, and the pH is acidic, and the skin after use is irritated. Therefore, it is suitably used within the above range.
