The cosmetic product of skin exfoliation containing film-forming fabrics and powders}

The present invention relates to a skin exfoliation cosmetic composition containing a film-forming resin and powder, more specifically, a low viscosity containing a film-forming resin and an exfoliating powder excellent in sebum adsorption and exfoliation ability as a main component The present invention relates to a cosmetic composition of a lotion type and a foamy cosmetic composition obtained by spraying after emulsifying by mixing in a metal container with a liquefied gas having a low boiling point. The cosmetic composition for exfoliation of the lotion type and foam of the present invention is applied to the skin. The film-forming agent gives the cleansing effect that can easily remove the dead skin cells, and the exfoliating powder promotes the peeling effect of skin cells and massage effect by the scrub to promote the skin's flexibility. Exfoliation of skin with excellent film-forming resin and powder It relates to a cosmetic composition for.

In the skin, the stratum corneum consists of 10 to 20 layers of dead cells and intercellular lipids and natural moisturising factor (NMF), which are present at the outermost part of the skin, protecting the skin from external contaminants and Plays an important role in preventing water loss. In healthy people, the turn-over cycle of the stratum corneum of the skin is about 4 weeks, and after a certain period of time, the old stratum corneum naturally peels off and a new stratum corneum is formed. However, due to internal factors such as aging and external factors such as ultraviolet rays, this turnover period becomes longer and unbalanced, the stratum corneum becomes old and stratified, the skin becomes dull, the skin tone is uneven, and the skin is acute. Occurs.

Existing skin exfoliation cosmetics are generally represented by two types.

First, it is a chemical exfoliating cosmetic, which is used to dissolve keratin chemically using AHA (Alpha Hydroxy Acid) or BHA (Beta-Hydroxy Acid), salicylic acid and plant extracts containing the same, or turnover cycle of skin It is a formulation that removes dead skin cells by shortening the action. In the above case, the use of a certain amount of exfoliation effect may be obtained for a certain period of time, but most of them have a disadvantage of causing side effects by causing skin irritation by using chemically active substances having a very low pH.

Second, it is a physical exfoliation cosmetics, mainly a cream or gel type of the formulation using a wax or a scrub to remove the exfoliated physically. In the above case, there is no chemical skin side effect than the chemical exfoliation formulation, but when used for the purpose of removing the exfoliation of the skin, the exfoliation is forcibly peeled off with wax or scrub, so the skin hurts and has an uncomfortable use.

Such chemical and physical formulations for exfoliation exfoliate both the skin roughness, skin tone imbalance, and the stratum corneum, which is the biggest cause of skin keratinization, and prevents skin keratination. However, there is a problem that the skin is ill due to chemical irritation or physical irritation after use. In addition, inconveniences such as giving a heavy and dull feeling when applied to the skin has been pointed out as a problem, the solution to this remains a problem.

Therefore, the inventors of the present invention have tried to solve the problems of the conventional chemical and physical exfoliant as described above, the lotion-type stable keratin with little viscosity with the film-forming resin and the exfoliating powder as the main component. The cosmetic composition for removal was prepared, and further, the exfoliation cosmetic composition of the lotion type was mixed with a low boiling point liquefied gas and filled into a metal can, followed by emulsification to prepare a foam exfoliation cosmetic composition. The present invention has been completed.

Therefore, the cosmetic composition for exfoliation of the lotion type and foam of the present invention can effectively remove the exfoliation safely without irritation to the skin by the soft film-forming resin and exfoliation powder when applied to the skin, the use of conventional chemical exfoliation formulation It is an object of the present invention to provide a skin exfoliant cosmetic composition containing a new concept of the film-forming resin and powder that can effectively overcome the limitations of skin irritation and discomfort when using a post-stimulus and physical exfoliant.

The present invention is 5 to 50% by weight of film-forming resin, 2 to 10% by weight of moisturizer, 35.5 to 70% of acrylate copolymer, polyvinyl alcohol, polyvinylpyrrolidone and polyacrylate. An aqueous phase containing weight percent; Oil phase part containing 1-5 weight% of nonionic surfactants, 0.5-5 weight% of waxes, and 2-7 weight% of emollients; Powder part containing 2 to 10% by weight of powder selected from polyethylene, polypropylene, polymethyl methacrylate, methyl cellulose, propyl cellulose, nylon and silica, and 1 to 10% by weight of additive selected from alcohol, perfume and preservative Characterized in that the cosmetic composition for exfoliating the skin comprising an additive.

In another aspect, the present invention is characterized in that the cosmetic composition for exfoliating the skin exfoliation comprising 65 to 99% by weight of the cosmetic composition for exfoliating the skin and 1 to 35% by weight of the liquefied gas in the range of -40 to -0.5 ℃. It is done.

The present invention will be described in detail as follows.

The present invention provides a lotion-type cosmetic composition comprising a film-forming resin such as an acrylate copolymer having excellent sebum adsorption and exfoliation ability and a powder for exfoliation such as polyethylene and vegetable cellulose, and a liquefied gas having a low boiling point. The present invention relates to a foamy cosmetic composition which is formed by mixing and emulsifying in a metal container, and then spraying. When the lotion type and foamy cosmetic composition for exfoliation of the present invention is applied to the skin, a soft film-forming agent is laminated on the skin. It can be easily removed without being irritated from and washed with water to remove it, and exfoliating powder such as vegetable cellulose can promote skin peeling action and give a massage effect by scrub to promote skin flexibility. Excellent film to get the effect at the same time It relates to a skin exfoliating cosmetic composition containing a resin and a powder.

If described in more detail for each component constituting the cosmetic composition for exfoliating the skin of the present invention.

First, the lotion-like exfoliation cosmetic composition having almost no viscosity will be described. The lotion-like exfoliation cosmetic composition is composed of a water phase part, an oil phase part, a powder part, and an additive part.

The water phase part consists of a film-forming resin, a moisturizer and purified water.

The film-forming resin uses a resin having excellent sebum adsorption and exfoliation ability, and the sebum adsorption and exfoliation ability as described above is derived from a unique shape that is dispersed in an emulsion and separated upon application to the skin. As such a film-forming resin, 5 to 50% by weight of one or more mixtures selected from acrylate copolymer, polyvinyl alcohol, polyvinylpyrrolidone, polyacrylate, and the like is used. At this time, if the amount of the film-forming resin is less than 5% by weight, the effective film-forming ability is not expressed, and it does not effectively remove the dead skin cells. If the amount exceeds 50% by weight, the film formation occurs due to excessive film formation. There is a problem of losing the ability to remove.

The moisturizing agent uses 2 to 10% by weight of one or more mixtures selected from glycerin, 1,3-butylene glycol, propylene glycol, dipropylene glycol, polyethylene glycol, and betaine. At this time, when the amount of the moisturizing agent is less than 2% by weight, there is a skin pulling phenomenon after use, and when the amount of the moisturizer exceeds 10% by weight, there is a problem that the separation speed of the film-forming resin is too slow when applied to the skin.

Purified water uses 35.5 to 70% by weight, but less than 35.5% by weight has a problem of high viscosity, and when used in excess of 70% by weight, there is a problem in that the amount of the film-forming resin separated when applied to the skin is reduced too much. .

Next, an oil phase part consists of surfactant, a wax, and an emollient agent.

The above-mentioned surfactants use nonionic surfactants having excellent emulsifying ability, and specifically include, for example, polyoxyethylene hardened castor oil, polysorbate 60, polysorbate 20, sorbitan monostearate, polysorbate 80 and glyceryl 1 to 5% by weight of one or more mixtures selected from stearate / laures-23 and the like is used. At this time, if the amount of the surfactant is less than 1% by weight, foam is not formed properly when it is ejected, and when it is used in excess of 5% by weight, the foam is too excessively generated to form a metal container (can, can There is a problem that does not shake inside.

Waxes are 0.5 to 5% by weight of polyhydric alcohols such as cetyl alcohol, stearyl alcohol and behenyl alcohol, and one or more mixtures selected from biswax, shea butter, and the like, as components which stabilize the emulsification. At this time, when the amount of the wax is less than 0.5% by weight, the emulsification is not preferably performed, so that the separation of the aqueous phase and the oil phase may occur, and when the amount exceeds 5% by weight, the viscosity may increase.

The emollient agent is an ester oil, and one or more mixtures selected from isopropyl palmitate, isopropyl myristate, glyceryl trioctanoate, 2-octyldodecanol and 2-octyldodecyl myristate, and the like. 2 to 7% by weight. At this time, when the amount of the emollient agent is less than 2% by weight, the desired emollient effect does not occur. When the amount of the emollient agent exceeds 7% by weight, the separation of the film-forming resin after application to the skin is delayed and transferred. There is a problem of shrinking.

Next, the powder part that serves to help exfoliation of the skin by promoting the separation of the film-forming resin from the lotion type fluid when applied to the skin, polyethylene, polypropylene, polymethyl methacrylate, methyl cellulose, propyl cellulose 2 to 10% by weight of one or more mixtures selected from the group consisting of nylon, silica, and the like is used. At this time, when the amount of the exfoliating powder is less than 2% by weight, the effect of the powder is not properly expressed, the exfoliation effect is lowered, and when the amount of the exfoliating powder exceeds 10% by weight, the powder phase is agglomerated to prepare a preferable lotion and foam formulation. There is no problem.

Finally, in addition to the above-mentioned main components, the exfoliating cosmetic composition of the present invention can be used in the range of 1 to 10% by weight if alcohol, flavoring, preservatives and ordinary additives can be used according to the choice of those skilled in the art.

The skin exfoliation cosmetic composition of the present invention, which is a lotion type composed of the above composition, is effectively irritated to the skin, effectively attenuates the excessively keratinized layer, and shortens the turnover cycle of the skin. At the same time, it moisturizes and emollients the skin, making it more clean and moist.

65-99% by weight of the lotion-type cosmetic composition for exfoliating skin of the present invention as described above is added to a metal container together with 1-35% by weight of liquefied gas having a low boiling point in the range of -40 to -0.5 ° C, and mixed and emulsified uniformly. When spraying at the same time, it is possible to produce a skin exfoliation cosmetics on the foam (Foam) containing a surfactant, an emollient agent, a film-forming resin, powder and the like.

That is, to prepare a cosmetic composition for exfoliating the skin of the lotion type, the aqueous phase consisting of the film-forming resin, moisturizer and purified water is rotated at a speed of homomixer 1500 ~ 2000 rpm in the temperature range of 70 ~ 80 ℃, mixed uniformly, The oil phase part which consists of surfactant, a wax, and an emollient agent is rotated at the speed of a paddle mixer 25-30 rpm in the temperature range of 70-80 degreeC, it mixes uniformly, and mixes with the said water phase part. Then, when applying the skin, add the exfoliating powder that helps to promote the separation and exfoliation of the film-forming resin, and mix by rotating at a speed of 25 ~ 30 rpm paddle mixer in the temperature range of 40 ~ 45 ℃, alcohol, fragrance And by mixing the additives, including preservatives, etc. to prepare a cosmetic composition for exfoliating skin lotion type.

When 65 to 99% by weight of the lotion-type cosmetic composition for removing skin exfoliation prepared as described above and 1 to 35% by weight of liquefied gas having a low boiling point are added to a metal container and mixed and emulsified at the same time, the surfactant and the film are formed. Resin, exfoliating powder, etc. form a foam. The lotion type skin exfoliation cosmetic composition has a relatively low viscosity and has a range of 20 to 500 cps, and thus can be easily mixed with the following liquefied gas to form a foam.

In this case, the boiling point of the liquefied gas to be used is in the range of -40.0 to -0.5 ° C. Specifically, one or more mixtures selected from propane gas, butane gas and dimethyl ether may be used.

When applying the cosmetic composition for exfoliating skin on the foam prepared as described above, the formed foam is layered on the skin and the old keratin is dissolved and separated from the skin, and when it is washed with water, the exfoliation and exfoliation dissolved in the foam The cosmetic composition is to be removed from the skin at the same time.

This makes it easy to remove dead skin cells and effectively reduce the turnover cycle of the skin without chemically or physically irritating the skin, thereby maintaining a cleaner and more flexible skin condition. Can provide.

Although this invention is demonstrated concretely by the Example, this invention is not limited by the following Example.

Example 1 Preparation of a Lotion Type Exfoliating Cosmetic Composition

Examples 3-4 and Comparative Examples 4-6: Preparation of cosmetic composition for exfoliation of foam form

Aluminum can of 80% by weight of the lotion-type exfoliating cosmetic composition prepared in Examples 1 to 2 and Comparative Examples 1 to 3 and 20% by weight of a low boiling point liquefied gas (3: 7 mixed gas of propane and butane gas) It prepared by putting in, mixing uniformly, and the button used the same thing generally used for hair mousse.

Experimental Example: Measurement of the exfoliation state

The degree to which the film-forming resin and powder are separated from the product is determined by coating the composition prepared in Examples 1 to 4 and Comparative Examples 1 to 6 on the skin, and then rubbing with the fingers with the naked eye to form the resin and powder for forming the film and the skin. The clumping was confirmed to be even, and the condition of removing dead skin cells was measured by visual comparison of skin condition before and after use of the composition with a skin measuring device PICO SCOPEMAN (manufacturer: MORITEX) commonly used in the art.

As a result, the lotion-type exfoliating cosmetic composition prepared according to Examples 1 to 2 and Comparative Example 1 was uniformly applied to the skin in an oily state, and then, after rubbing by hand, the keratin and the film were aggregated from the skin surface. Exfoliation is removed, easy to use without excessive agglomeration of the exfoliating powder itself.

On the other hand, Comparative Example 1 was excellent in exfoliation power, but it was not easy to use because the film forming resin and exfoliating powder were excessively aggregated. In Comparative Example 2, the exfoliating film and the exfoliating powder did not come out separately. And Comparative Example 3 was not able to obtain a lotion-like exfoliating cosmetics.

In addition, in the case of Examples 3 to 4 made of a foam-like composition, after the foam is applied to the skin similar to the case of Examples 1 and 2, the film and keratin are agglomerated and removed from the skin surface by rubbing with a finger. Easy to use without excessive clumping of the exfoliating powder itself.
However, in Comparative Examples 4 to 6, the exfoliation power was excellent at a level similar to that of Comparative Example 1, but the film-forming resin and the exfoliating powder were excessively aggregated to facilitate the use, and in Comparative Example 5, the comparative example Similar to 2, the film-forming resin and the exfoliating powder did not come out separately, so there was no exfoliation effect.

As described above, the skin exfoliation cosmetic composition containing the film-forming resin and the exfoliating powder that is dispersed in the emulsion phase and separated upon application to the skin includes a lotion type as well as a low boiling point liquefied gas. It can also be used in the form of foam, which has distinctive components and formulation characteristics that are distinct from the existing exfoliating cosmetic composition, and when it is used, turn of the stratum corneum due to internal factors such as aging or external factors such as ultraviolet rays. The over cycle is non-uniform and the skin becomes dull and the skin tone is uneven, and the skin keratin phenomenon is alleviated. In addition, the moisturizing and emollient effects are provided to make the skin more clean and moist.                     

In addition, unlike the conventional chemical and physical exfoliation cosmetic composition can be expected to differentiate the effect of removing the irritation or discomfort to the skin when used.
