20210361545
The present application claims the benefit of priority based on Korean Patent Application No. 10-2017-0164288 filed on Dec. 1, 2017, and the entire contents disclosed in the description and drawings of the corresponding allocation are incorporated in the present application.
The present invention relates to a cosmetic composition for immediately improving skin conditions such as skin wrinkles, skin elasticity, and the like.
Most of cosmetics for wrinkle improvement that are currently on sale improve wrinkles by the principle of preventing decomposition and promoting synthesis of skin components such as collagen, elastin, hyaluronic acid, and the like, as the active ingredient penetrates the skin. However, this approach has a disadvantage in that there is a difference in the effect depending on the skin absorption rate of the ingredient having a wrinkle improvement effect, and it takes a long time for consumers to experience the effect.
Therefore, products, which consumers can experience the wrinkle improvement effect as soon as they apply them, are being released. This method is largely divided into two ways. The first is a method for covering wrinkles using a particle that can cause diffused reflection. The second is a method for improving wrinkles using a material that causes shrinkage when applied to skin, and products are manufactured using water soluble polymers or hydrophilic polyhydric silicates. However, these two methods have problems in that the persistence is weakened by moisture after application, and in particular, due to agglomeration between particles, whitening and cracking occur, thereby rather making skin defects prominent. In addition, when the hydrophilic polyhydric silicates are applied to a formulation, problems have been found in that the effect is significantly reduced in the acidity (pH 3˜9) applicable to cosmetics.
In order to solve such a high pH, it has been reported that chitosan is applied to bentonite (Korean Patent Publication No. 10-2016-0002896), but the reality is that it is difficult to use chitosan due to safety issues related to allergies.

The polymer which ionically interacts with the anionic particle of the cosmetic composition according to the present invention may be comprised in an amount of 0.01 to 15% by weight (w/w) based on the total composition. More specifically, it may be 0.1 to 10% by weight (w/w), and much more specifically, it may be 1 to 5% by weight (w/w).

The cosmetic composition according to the present invention may comprise components commonly used for the cosmetic composition, and as one example, it may comprise a common preservative such as a moisturizer, an ultraviolet absorber, an ultraviolet scattering agent, vitamins, plant extracts, a skin astringent, an anti-inflammatory agent, a cell activator, a vasodilator, a blood flow stimulant and a skin function agonist, and a carrier, and the like, in addition to various kinds of additives such as a surfactant, a pH adjusting agent, a coloring matter, a flavoring agent, a pigment, a preservative, a disinfectant, a thickener, an anti-oxidant, a stabilizer, a solubilizer, a sequestering agent, a freshener, a deodorant, an emulsifier, a solubilizing agent, and the like, and its formulation and additive components are not limited to the above contents. In addition, the components may be introduced in an amount commonly used in the skin science field.
The formulation of the cosmetic composition according to the present invention is not particularly limited, but it may comprise cosmetic composition combination components commonly used in the technical field to which the invention pertains, depending on the formulation to be manufactured. The cosmetic composition of the present invention may be formulated into for example, liquid products, lotion, essence, cream, sun lotion, sun cream, makeup base, foundation, BB cream, stick products or balm type products, or the like, but not limited thereto. In addition, depending on the formulation to be manufacture, it may further select and add in combination oils, water, a surfactant, a moisturizer, a lower alcohol, a thickener, a chelating agent, a preservative, a flavoring agent, and the like. Furthermore, the cosmetic composition according to the present invention may comprise a sunscreen, a light scattering agent, and the like, and its formulation and additive components are not limited to the above contents. Moreover, the components may be introduced in an amount commonly used in the skin science field.

Hereinafter, the present invention will be described in more detail by examples. However, these are intended to illustrate the present invention in more detail, but the scope of the present invention is not limited thereto.
In the present experimental example, to find an appropriate combination ratio of the cosmetic composition for immediate wrinkle improvement of the present invention, after mixing raw materials using water as a solvent, the shrinkage was evaluated using the following method.
(1) Measurement Method
On a thin film silicone surface with a thickness of 0.1 mm and width 4 cm×height 20 cm, the mixed raw materials were applied in a thickness of 100 μm. Then, after drying in a thermo-hygrostat chamber with the humidity of 50% and the temperature of 37° C. conditions, the shrinkage was calculated using the following equation.
(2) Shrinkage According to Kinds of the Anionic Particle
To evaluate the wrinkle improvement efficiency, the shrinkage was measured by mixing polyquaternium-10 to various anionic particles. For comparative evaluation, the shrinkage in case of using the anionic particle only was also measured. The result was shown in the following table.
As the result of the experiment, it was confirmed that the anionic particle also showed the skin shrinkage effect, but the effect was more increased in case of mixing it and the ionically interacting polymer, and in particular, laponite had a full 3 times increased skin shrinkage effect when mixed with the ionically interacting polymer than used alone.
(3) Shrinkage According to Kinds of the Ionically Interacting Polymer
To evaluate the wrinkle improvement efficiency, the shrinkage was measured by mixing laponite which is an anionic particle with the excellent effect to various polymers which ionically interacts with the anionic particle. For comparative evaluation, the shrinkage in case of using the polymer alone was also measured. The result was shown in the following table.
As the result of the measurement, it was confirmed that there was no skin shrinkage effect when the polymer which ionically interacts with the anionic particle was comprised in an amount of 1% by weight, but the excellent skin shrinkage effect was shown when mixed with the anionic particle.
When the result is represented to a graph in combination, it is as
In the present experimental example, whether the formulation stability is maintained even in pH 6 due to interaction of the anionic particle and the polymer used in the composition of the present invention was evaluated.
The pH of the control group was adjusted to 6 using a small amount of hydrous citric acid after adding bentonite 3% by weight to purified water 97%. The pH of the experimental group was adjusted to 6 using a small amount of hydrous citric acid after adding polyquaternium-10 1% by weight to purified water 96%. The manufactured formulation was under a stability test using Freeze Thaw method (F/T). After freezing at −20° C. for 24 hours and then raising the temperature at a room temperature, the stability evaluation for elapsed time change was progressed. A total of 5 repeated experiments were conducted, and the result was shown in the following table.
On the other hand, the photograph of the control group in which freeze/thaw (F/T) was conducted once and the photograph of the experimental group after conducting 5 times, according to the above experimental method were included in
The cosmetic composition exhibiting the immediate skin wrinkle improvement effect of the present invention was manufactured using the raw materials shown in the following table.
The raw materials of numbers 1˜3 were added to the raw material of number 5, and they were mixed for 30 minutes while raising the temperature from 40° C. Then, adding the raw material of number 4, they were mixed for 10 minutes. Meanwhile, the raw materials of numbers 6˜11 were added to the raw material of number 12 and then they were mixed for 30 minutes while heating to 40° C. Then, the mixed solution of numbers 1˜5 prepared in advance was added, and they were mixed for 15 minutes, thereby manufacturing the cosmetic composition.
For the manufactured cosmetic composition, the shrinkage was evaluated using the shrinkage measurement method used in the experimental example 1. As the result of evaluation, 0.75% shrinkage was shown. On the other hand, as the result of evaluation using a pH meter, the manufactured cosmetic composition exhibited weak acidity.
In the present experimental example, the immediate skin wrinkle improvement effect of the cosmetic composition exhibiting the immediate skin wrinkle improvement effect of the present invention manufactured in the example 1 was to be confirmed. Before the experiment, eyes of two experimenters were photographed, and in 5 minutes after applying the cosmetic composition of the present invention, the eyes of the experiments were photographed, to confirm the wrinkle and eyebag improvement effect utilizing naked eyes and a program (used equipment: Vsiosphere 3D, Primos).
As the result of the confirmation, as could be confirmed in
Moreover, as the result of calculating by the program, the wrinkles were improved by 14.76% compared to those before application, and the eyebags were reduced by 37.05%.
