Description

Cosmetic composition for enhancing skin elasticity {Cosmetic composition for improving the skin elasticity}

The present invention relates to a cosmetic composition for enhancing skin elasticity, and more particularly, to a cosmetic composition containing a saccharide surfactant, a fatty alcohol and starch as an active ingredient.

In general, cosmetics are intended to clean the body, to make themselves beautiful and attractive, and to prevent aging by protecting the skin or hair from ultraviolet rays or drying. In addition to the cosmetic area of moisturizing products to solve skin problems caused by primary cleanliness and dryness, the area of cosmetics has become a little wider, and is active in developing its beauty by preventing or caring for skin problems such as decreased elasticity, whitening, and wrinkles. It is used as a means.

The decrease in elasticity of the skin, which is found at a relatively young age, is not accompanied by the sagging of the skin, so it is invisible to the naked eye and can only be felt by touching it. Skin elasticity deterioration of humans is almost always accompanied by skin swelling phenomenon. The decrease in elasticity of skin is classified into simple unsupple skin and elderly skin flabby skin with skin swelling. have.

The cause of the decrease in elasticity of the skin is primarily due to the inability of the skin cell layer to exhibit sufficient strength despite the vitality of the young age, since the skin cell layer is not supplied with sufficient nutrients. In fact, this type of skin is commonly found in young women in their 30s and older, and the nutritional deficiencies of skin cells are often due to unexpected diets. Another cause can be found in the ECM structural changes that make up most of the dermis and actually support the skin. As you age, collagen or elastin tissues are damaged and broken or deformed due to sunlight photolysis. As the ECM tissue collapses, the elasticity decrease occurs due to aging, and the skin elasticity decreases due to the weakening of the subcutaneous fat layer and the muscle layer. The elasticity is lowered and the muscles become poor, resulting in the same result as the depression of the fat layer. This problem is not only a problem on the face but a skin problem on the whole body.

In order to improve the skin troubles of the decrease in elasticity, the skin troubles are solved by physical massage therapy, lapping therapy or surgery, and in the cosmetic field, considering the characteristics of the skin with reduced elasticity, strengthening moisturizing and promoting cell differentiation through exfoliation of the stratum corneum. In addition, elastin and collagen enhancement or elastin degrading enzymes for strengthening the dermal layer have been released. However, the customer wants to improve elasticity, and he wants a product that has an immediate physical effect such as a massage, and he has a high level of satisfaction with a product that has an immediate improvement in elasticity. A large amount of polymer is used to launch the product. Therefore, the satisfaction of existing skin elasticity improvement products is low, and the development of a cosmetic having excellent skin elasticity and enhancement effect as well as providing immediate elasticity has become an urgent and important problem.

Therefore, the low level of satisfaction with the immediate cognitive efficacy of the existing product for improving skin elasticity has become an urgent and important problem to develop a cosmetic showing the cognitive efficacy of skin elasticity enhancement immediately.

Thus, the present inventors have studied the factors that can affect the improvement of the actual elasticity of the skin while giving cognitive efficacy for improving skin elasticity at the same time to solve the problems as described above, initial application, correct The present invention has been completed by discovering that factors affecting the post-finish feeling, skin permeability and absorbency after application are different depending on the composition in the formulation.

Accordingly, an object of the present invention is to provide a cosmetic composition for enhancing skin elasticity that provides elasticity to the skin immediately by applying a flexible film on the skin in a fast absorbing feeling and a flexible coating on the skin when applying the elasticity improving product.

In order to achieve the above object, the present invention is a cosmetic composition containing a saccharide surfactant, fatty alcohol and starch as an active ingredient, in the sense of use when applying the skin in the sense of fast absorption and forming a flexible film on the skin immediately applied skin It provides a cosmetic composition for enhancing skin elasticity to provide a sense of elasticity.

The elasticity used in the present invention refers to a phenomenon of giving elasticity to the skin by changing the feeling of use through the formulation and external physical tightening, and the raw materials used are described in detail below.

The present invention is a cosmetic composition containing a saccharide surfactant, fatty alcohol and starch as an active ingredient, the active ingredient is 0.1 to 10% by weight depending on the content of the saccharide surfactant active ingredient with respect to the total weight of the composition, the active ingredient of fatty alcohol Characterized in that the cosmetic composition, characterized in that 0.1 to 20% by weight depending on the content of and 0.1 to 2% by weight depending on the content of the active ingredient of starch.

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

The saccharide surfactant is a natural, food-based saccharide surfactant derived from sugar cane and palm oil instead of a petroleum surfactant, and has a good skin affinity, soft and smooth application, and changes in phase rapidly and adheres to the skin. As a raw material, it has excellent finish and can be used as a raw material for formulating elastic products. Specifically, sucrose polystearate, polyglyceryl-3 methylglucose distearate, and cetearyl glucoside (Cetearyl Glucoside) and C12-20 Alkyl Glucoside (C12-20 Alkyl Glucoside) may be used at least one selected from the group consisting of sucrose polystearate (Sucrose Polystearate) is preferably used. The saccharide surfactant is contained in an amount of 0.1 to 10% by weight depending on the content of the active ingredient based on the total weight of the composition. If the active ingredient content of the saccharide surfactant is more than 10% by weight, the hardness of the emulsion formulation is high, because the poor swelling property is difficult to use as a cosmetic problem occurs.

In addition, in the present invention, a fatty alcohol is used for forming a flexible film on the skin in order to feel a firm elasticity in the skin immediately after applying the fatty alcohol having 12 to 22 carbon atoms, cetearyl alcohol (cetearyl) alcohol, behenyl alcohol, beylyl alcohol, batyl alcohol, arachidyl alcohol, and myristyl alcohol may be one or more selected from the group consisting of. Use behenyl alcohol.

 The fatty alcohol is contained in an amount of 0.1 to 20% by weight depending on the content of the active ingredient based on the total weight of the composition. When the content of the fatty alcohol exceeds 20% by weight of the active ingredient, there is a problem that the hardness of the emulsion formulation is high and the bleeding property is difficult to be used as a cosmetic.

Starch, a natural polymer used in the present invention to be used with fatty alcohols to give a physical elasticity to the skin to form a more flexible and durable film, is a substance produced by plants with chlorophyll through photosynthesis. It refers to at least one selected from the group consisting of corn starch (corn starch), sweet potato starch (sweet potato starch), potato starch (potato starch) and wheat starch (wheat starch), preferably corn starch is used. .

The starch is contained in an amount of 0.1 to 2% by weight depending on the content of the active ingredient based on the total weight of the composition. If the content of the starch exceeds 2% by weight of the active ingredient, the hardness of the formulation is high, because the poor swelling problem is not suitable for use as a cosmetic problem occurs.

The cosmetic composition according to the present invention contains a skin elasticity improving efficacy component for improving long-term actual skin elasticity. As a specific example, one or more selected from the group consisting of oleanolic acid, retinol, adenosine, and peptides is used, and preferably oleanolic acid is used. The content to be used is a general content in which the effect of the active ingredient is recognized, and in the present invention, oleanolic acid uses 0.05% by weight based on the total weight of the composition.

The formulation of the present invention is not particularly limited and may be formulated into a skin, lotion, essence, cream, pack, mask, and the like in the cosmetic range.

In the present invention, the oil-in-water emulsion emulsion formulation is light and refreshing advantage and the adhesion is improved when applied to provide a feeling different from the general emulsion.

The present invention, by using a saccharide surfactant and fatty alcohol to not only adhere to the skin with a fast change of phase, but also provides effective skin pulling and physical skin elasticity due to encapsulation to help improve skin elasticity lowering various formulations It can be used as a cosmetic.

According to the present invention, by using starch, which is a natural polymer, the adhesion is improved during application due to the change of the fast phase of the saccharide surfactant, and the water of the starch together with the film of the fatty alcohol contained forms a harder film by evaporating the moisture of the physical elasticity. Increasing synergistic effects on the effectiveness of elasticity improvement products.

In addition, the cosmetic of the present invention will help solve the anxiety of modern people due to the decrease in elasticity by providing a physical effect on the immediate elasticity as well as the improvement of skin elasticity when applying the skin.

The present invention will be described in more detail by the following examples and test examples. However, the following examples and test examples are only for the understanding of the present invention, and the scope of the present invention is not limited by these examples and test examples in any sense.

 [Examples 1 to 7 and Comparative Examples 1 to 2]] Preparation of cosmetics for enhancing skin elasticity

As shown in Table 1, by varying the content (wt%) of the saccharide surfactant, fatty alcohol, starch, the cosmetic composition containing oleanolic acid as in Examples 1 to 7 and Comparative Examples 1 to 2 (water-in-oil ( O / W) emulsion formulations) were prepared. Comparative Example 1 is an example of preparing an O / W emulsion base using polysorbate 60, a basic surfactant, and glyceryl stearate / pG-100 stearate, and Comparative Example 2 was prepared by using oleanolic acid in Comparative Example 1. It is added. Example 1 added only sucrose polystearate, a saccharide surfactant, to the formulation of Comparative Example 2, and Example 2 added only behenyl alcohol, a fatty alcohol, to the formulation of Comparative Example 2. In Example 3, only Corn Starch, which was Starch in Comparative Example 2, was added. Examples 4 to 7 are to see the synergistic effect when using a saccharide surfactant, fatty alcohol and starch in the case of Example 4 was prepared by further adding behenyl alcohol to Example 1 prepared above, In the case of Example 5 was prepared by the addition of corn starch and sucrose polystearate which is a saccharide surfactant instead of the basic surfactant in Comparative Example 2. Example 6 was prepared by adding behenyl alcohol and corn starch to the formulation of Comparative Example 2, in the case of Example 7 using sucrose polystearate which is a saccharide surfactant instead of the basic surfactant in the formulation of Comparative Example Both alcohol and corn starch were used.

Examples 1 to 7 and Comparative Examples 1 to 2 were prepared by the following method.

(1) The aqueous phase components are uniformly mixed and dissolved by heating at 70 ° C.

(2) The oily ingredients are mixed and dissolved by heating at 75 ° C.

(3) The above (2) is slowly added to the above (1) while stirring (homomixing) at 70 ° C to form an emulsion (oil-in-water emulsion) formulation.

(4) The oleanolic acid base is stirred at 60 DEG C and dissolved and cooled to 40 DEG C or lower.

(5) After (3) is cooled to 40 ° C. or lower, (4) is added and stirred to mix uniformly.

[Test Example 1] Emotional elasticity enhancement effect by the physical effect of the formulation

In order to confirm the effect of improving skin elasticity immediately after using the product, the cream formulations of Examples 1 to 7 and Comparative Example 2 prepared above were used for 20 Korean women in their 30s and then evaluated for immediate feeling of use. The evaluation of the feeling was made to 20 panelists after applying the contents to each of the evaluation items, and the feeling of lifting the struck skin was felt / the feeling of elasticity was felt on the skin.I don't know.The three items were marked with their own feelings. The result was shown. The results are shown in Table 2 below.

As can be seen in Table 2, the sucrose polystearate as a saccharide surfactant, behenyl alcohol as a fatty alcohol, corn starch as starch, as in Examples 1, 2 and 3 than the formulation of Comparative Example 2 In Comparative Example 2, which was not added as an active ingredient, the satisfaction with immediate skin elasticity was higher, especially when only sucrose polystearate was used in Example 1, Just before the absorption, the feeling of using the emulsion phase can be used, and the associative effect of the contents being absorbed into the skin can be obtained, thereby improving the immediate elasticity of the skin. When two kinds of compositions were used together as in Examples 4 to 6, the satisfaction level was higher than that of each raw material alone. Especially, as in Example 7, sucrose polystearate and fatty alcohol were used as the saccharide surfactant. The combination of hexyl alcohol and starch with corn starch yielded the highest level of skin elasticity. Bezelyl alcohol and corn starch were supple and thin on the skin together with the specific feeling of sucrose polystearate. Since the film is formed, it is believed that the immediate immediate skin elasticity is felt from this.

Test Example 2 Human Test on Skin Elasticity

In order to compare the skin elasticity recovery effect of the emulsifiers prepared in Comparative Examples 1 and 2 and Examples 4 to 7, the 280 women in their 30s to 40s were divided into 14 groups of 20 people as one group. It was. The experimental method is as follows.

Each group was given the formulations of Examples 4 to 7 and Comparative Examples 1 to 2 and applied once a day for 1 month, and after 1 month, a cutometer (SEM474, Courage +) capable of measuring skin elasticity Khazaka electronic GmbH. Germany) was used to measure the elasticity of the facial area and compare it with before application.

The experimental results are shown in Table 3 below, and the Table 3 values are averages of the groups.

As can be seen in Table 3, Examples 4 to 7 were all synergistic effects when using the saccharide surfactant, fatty alcohol and starch, Example using both saccharide surfactant, fatty alcohol and starch In the formulation of 7 it was confirmed that the skin elasticity was the most improved.
