Description

Ÿ‡-COSMETIC COMPOSITION FOR CARING SKIN SURFACE USING WET-PEELING TECHNOLOGY with peeling technology applied

The present invention relates to a cosmetic composition for managing keratin of the skin, and more particularly, to a cosmetic composition for keratin care that prepares the skin texture by generating a physical gomage after first washing. More specifically, unlike the conventional gommage-type physical exfoliant containing carbomer and acrylate-based thickeners, which generate gommage in dry skin, the cosmetic composition of the present invention is It is characterized in that it can generate gomage even on wet skin.

In the skin, the stratum corneum is located at the outermost layer of the skin and plays an important role in protecting the skin from various stimuli and contaminants in contact with the skin and preventing moisture loss. In general, dead skin cells naturally exfoliate after a certain period of time and a new stratum corneum is formed. , it can cause various skin troubles such as acne as well as uneven skin tone. To solve this problem, various exfoliating cosmetics that can artificially remove the stratum corneum have been developed, and can be broadly divided into two types: a chemical type and a physical type.

First, a chemical exfoliating cosmetic is a formulation that chemically dissolves and removes dead skin cells using AHA (Alpha Hydroxy Acid), BHA (Beta-Hydroxy Acid), salicylic acid, and plant extracts containing them. Korean Patent Application Laid-Open No. 10-1325092 proposes a cosmetic composition containing citron extract as an active ingredient to reduce dead skin cells and improve skin texture. These chemical exfoliating cosmetics have the advantage of not needing to be washed off, but they have the disadvantages of being relatively slow in effect and most of them having very low acidity, which irritates the skin and causes various skin side effects.

In contrast, the physical exfoliation method is to remove dead skin cells by rubbing the skin with cosmetics added with various types of scrubs, etc. You can feel the physical stimulation by using it. Commonly used scrubs include natural scrubs made by grinding synthetic raw materials such as polyethylene and hard seeds such as cellulose, mannan, walnut shells, peach or apricot seeds, and crystals such as salt, sugar calcium chloride, aluminum oxide, and sodium bicarbonate. A scrubbing agent is used. Cosmetics are a type of formulation characterized by physically exfoliating dead skin cells using wax, scrub, and gommage. Korean Patent Application Laid-Open No. 2010-64435 proposes a cosmetic composition for exfoliating dead skin cells that removes dead skin cells and wastes using sodium chloride particles and a surfactant as a scrub formulation. Such a cosmetic composition for physical exfoliation does not have any chemical side effects on the skin, but has a disadvantage in that it may physically injure the skin or cause irritation.

Korean Patent Application Laid-Open No. 10-2014-0055689 discloses a cosmetic composition for exfoliating a gomage type with reduced skin irritation having a foam phase while including an acrylic copolymer film-forming resin and an organic acid. At this time, the gommage-type cosmetic composition for exfoliating the skin goes through a process of removing dead skin cells by cleansing the makeup and removing moisture, then applying the formulation and rolling it a certain number of times to create a gommage, and then wash it again It has the disadvantage that it is cumbersome and inconvenient to use because it has to be used.

Accordingly, the present inventors conducted additional research on formulations that can generate gomage even after washing the first face and in a wet state, and whether or not gomage is generated due to the presence or absence of moisture, which was considered as the above disadvantage when using a specific raw material, and It was confirmed that skin irritation that may occur when rolling on dry skin a certain number of times or more can be overcome, and the present invention has been completed.

The present invention relates to a cosmetic composition for keratin care that manages skin texture using gommage generated through the reaction of a high molecular polymer with a cationic surfactant.

An object of the present invention is a cosmetic composition for exfoliation comprising a polymer and a cationic surfactant, wherein the polymer is a carbomer, an acrylate/C10-30 alkyl acrylate crosspolymer or a mixture thereof, and the cationic surfactant is achieved by the cosmetic composition for exfoliating the skin, characterized in that PEG-5 stearylammonium chloride.

Preferably, the cosmetic composition according to the present invention contains 0.1 to 5.0% by weight of the polymer polymer based on the total weight of the cosmetic composition, and may contain 1 to 30% by weight of the cationic surfactant based on the total weight of the cosmetic composition.

The cosmetic composition according to the present invention can conveniently and effectively manage keratin while reducing the cleansing step by one step by freely generating gomage even on wet hands while maintaining the effective keratin management effect and managing the skin texture. have.

All technical terms used in the present invention, unless otherwise defined, have the following definitions and have the meanings as commonly understood by one of ordinary skill in the art of the present invention. In addition, although preferred methods and samples are described herein, similar or equivalent ones are also included in the scope of the present invention.

The term "about" means 30, 25, 20, 15, 10, 9, 8, 7, 6, 5, means an amount, level, value, number, frequency, percentage, dimension, size, amount, weight or length varying by 4, 3, 2 or 1%.

Throughout this specification, unless the context requires otherwise, the terms "comprises" and "comprising" include, but are not limited to, a given step or element, or group of steps or elements, but any other step or element, or It is to be understood that a step or group of elements is not excluded.

The present invention relates to a cosmetic composition for exfoliation comprising a polymer and a cationic surfactant.

Preferably, the polymer is a carbomer, an acrylate/C10-30 alkyl acrylate crosspolymer, or a mixture thereof.

More preferably, the polymer may be a mixture of acrylate/C10-30 alkyl acrylate crosspolymer and carbomer. When a mixture of acrylate/C10-30 alkyl acrylate crosspolymer and carbomer is used, it can be used by mixing in a weight ratio of 1-2: 1-2.

According to the most preferred embodiment of the present invention, the high polymer in the cosmetic composition of the present invention is 0.01 to 5% by weight, more preferably 1 to 3% by weight, based on the total weight of the cosmetic composition. If the content is less than 0.01% by weight, viscosity is difficult to form and gomage formation is not sufficient. A content range is preferred.

The cationic surfactant used in the present invention is preferably PEG-5 stearylammonium chloride. PG-5 stearylammonium chloride used as an active ingredient in the cosmetic composition of the present invention has an amphoteric moiety, so it provides some water resistance while being washed out in water. used

The amount of cationic surfactant as an active ingredient in the cosmetic composition of the present invention is 0.1 to 30% by weight, more preferably 5 to 20% by weight, based on the total weight. If the content is less than 0.1% by weight, it is similarly difficult to form a viscosity and the formation of gomage is not sufficient. Since there is no content, the above content ranges are presented.

The cosmetic composition of the present invention improves the phenomenon that the conventional keratin care cosmetic composition does not peel in a wet state. In the case of conventional keratin care products containing carbomer and acrylate-based thickeners, the moisture in the formulation is blown away during the rolling process of applying the formulation to dry skin after washing, and the aggregation phenomenon between the anion of the thickener and the cationic polymer causes a gourmet effect. The principle of occurrence is applied, but there is a limitation and inconvenience in that you have to wash your face and completely remove the water before using it. This is a keratin care product that has the inconvenience of having to go through the washing step once more, but due to the keratin management effect, it is a keratin care product that is used. The disadvantage is that the effect is relatively insignificant. The cosmetic composition of the present invention improves the disadvantages of the conventional products described above.

The ingredients included in the cosmetic composition of the present invention may include ingredients commonly used in cosmetic compositions in addition to the active ingredient as an active ingredient, for example, conventional ingredients such as antioxidants, stabilizers, solubilizers, vitamins, pigments and fragrances. adjuvants, and carriers.
