Description

[0001] The present invention relates to a cosmetic composition having excellent moisture retention and sustaining power,

The present invention relates to a cosmetic composition, and more particularly, to a cosmetic composition which has a concealing ability to conceal defects of the skin and can prevent the skin from being buried, has excellent durability, .

Among cosmetic compositions which can hide skin defects, water-in-oil (w / o) emulsion contains oil, water, emulsifier and pigment and is widely used as a universal formulation by maintaining a constant viscosity . It has a cream or lotion shape due to viscosity, but it is heavy because it contains a nonvolatile oil content and a waxy thickening agent. In the case of a solid cosmetic preparation made only of a powder component, there is a disadvantage in that it is easy to carry and has a convenient feeling of use, but it causes a lot of powder during use, breaks easily, and deteriorates its sustainability.

Thus, a cosmetic composition in which a powder component is dispersed only in an oil phase component has been proposed. In this case, the use of oil has excellent water resistance and durability, but has a heavy feeling, have. In addition, even in the case of a conventional oil-in-water (o / w) emulsion formulation, it easily fades out after application of the skin, and particularly because the outer film-forming component is water-soluble, have.

The inventors of the present invention have made intensive studies on a method capable of solving the problems of such a cosmetic composition. As a result, surprisingly, when a cosmetic composition is constituted by a formulation containing minimized water content in a water-in-oil type formulation, moisturizing power is given to the skin with a light feeling It has a certain viscosity and has a merit that it does not flow down when it is applied to skin, and it can contain both oil phase and water-soluble film forming agent at the same time, and has excellent covering ability and can last for a long time without being buried.

In order to solve the problems of the prior art as described above, the present invention can prevent the skin from being buried while having a concealing concealment of defects of the skin, has excellent durability, has no skin pulling phenomenon, To provide a cosmetic composition having excellent covering power.

It is another object of the present invention to provide a method for producing such a cosmetic composition.

In order to achieve the above object,

 Or a pharmaceutically acceptable salt thereof.

As described above, the cosmetic composition according to the present invention can prevent the coloring and powder components solidified by the natural rosin from adhering to the skin, and is excellent in waterproof function, , And the ammonium acryloyldimethyltaurate / VIPICO polymer as an aqueous phase component forms a moisture barrier film on the skin, so that there is no skin pulling phenomenon, and there is an advantage of excellent covering power and water holding power. Furthermore, even when a volatile oil is contained in a high content, small reverse micelles are formed by a small amount of aqueous phase components, and very stable viscosity can be obtained.

Hereinafter, the present invention will be described in detail.

In the process of studying the cosmetic composition, the present inventors have found that after dissolving natural rosin with caprylic / capric triglyceride together with volatile oil in a cosmetic composition by heating , the dimethicone / vinyl dimethicone crosspolymer, dimethicone crosspolymer and When the volatile oil is added, the volatile oil volatilizes to prevent the powder component from being adhered to each other due to natural lignin bonding, and when the water-soluble portion of the purified water and the ammonium polyacryloyldimethyltaurate / VFPC polymer is added , It has been found that a cosmetic composition can be obtained by forming a moisturizing film with a novel formulation having a viscous cosmetic composition by such an aqueous phase and thereby exhibiting excellent durability of color development and reducing skin pulling phenomenon. It is.

(W / o) emulsion formulation has a heavy texture because it is composed of wax, higher fatty acid alcohols, glycerin, butylene glycol, emulsifier, and powder (pigment, etc.) Shows a novel formulation which is very light, consisting of an oil phase, a powder phase and a small amount of water phase. The new formulation has the advantage that the oil phase, the powder phase and the water phase are not separated from each other and the stability is excellent even in a state of high temperature and low temperature. The surfactant acts on the oily component of the oil and a small amount of the aqueous phase component to maintain its stability and has a viscosity due to adhesion of the powder component and formation of reverse micelles.

[ Experimental Example ]

The cosmetic compositions prepared through the above Examples and Comparative Examples were measured as 'buried and water-insoluble' by the following method, and the 'color persistence, degree of non-stickiness, skin pulling and dry feeling' And the instrument was evaluated for moisture.

Measures the degree of burying and watering

A) 0.1 g of the cosmetic composition of the examples and comparative examples was uniformly applied to the skin of a person [(horizontal) x (length) = (3 cm) x (3 cm)] and after about 10 minutes, Thereby pressing the application site. At this time, the weight change of the tissue was measured.

B) 0.1 g of the cosmetic composition of the examples and comparative examples was uniformly applied to an artificial skin [(horizontal) × (length) = (3 cm) × (3 cm)] to the extent that the hair was not removed in water, The weight change before and after the test was measured by allowing the composition to be washed out of the water by artificially immersing it in water for 1 hour in an automatic shaker.

The procedure was repeated three times each to minimize the error of the test, and the average values thereof are shown in Tables 3 and 4 below. Here, the fact that the change in the weight is small means that there is little burial, and that the water is washed away in the water, which is excellent in durability.

As shown in Tables 3 and 4, Examples 1 to 5 were superior to Comparative Examples 1 to 5 in that they remained burnt and not soaked in water.

That is, the comparative example (1) is a formulation in which the pine resin is contained in a water-in-oil type formulation but not the ammonium acryloyldimethyltaurate / VIPICO polymer, and the comparative example (2) is a formulation containing rosin and ammonium acryloyldimethyltaurate / Comparative Example 3 does not contain rosin but is an aqueous formulation containing ammonium acryloyldimethyltaurate / VIPICO polymer. Comparative Example 4 is comparative only with oil formulations containing rosin but not water components Example (5) consists of oil-in-water emulsion which does not contain both rosin and ammonium acryloyldimethyltaurate / VIPICO polymer.

Comparative Examples 1 and 4 containing rosin exhibited less occurrence of burying, but Comparative Example 1 had no ammonium acryloyldimethyltaurate / Vpicopolymer and was more likely to be buried than in the Example formulations. Comparative Example 4 Formulation Was excellent in remained as an oil-based formulation, but had a lack of moisturizing effect, resulting in the inclusion of the skin. Comparative Examples (2) and (3) did not contain the rosin, and the burying phenomenon was more common than the rosin-containing formulation. Comparative Example (5) Although the formulation did not contain the rosin, the formulation contained only the oil.

Sensory evaluation (color persistence, no embossing, skin pulling and dry feeling)

The cosmetic compositions of the present invention and the comparative example were subjected to daily use of about 0.5 g each day for 21 days, and the color persistence, the degree of non-embossing, the skin pulling and the dry feeling were evaluated by sensory evaluation Respectively. The color persistence and the degree of non-embossing were evaluated as upper, middle, and lower, respectively. Skin pulling and dry feeling were indicated as to whether or not they occurred. The results are shown in Tables 5 and 6 below.

As shown in Tables 5 and 6, Examples 1 to 5 were superior in color persistence and degree of dullness to Comparative Examples 1 to 5, and in particular, the formulations formed only with conventional oil-based formulations were superior to those of Comparative Examples 1 to 5 Color persistence was superior to other comparative formulations, but skin tension and dryness were very high.

Moisture power  Measure

The skin moisture test before and after the application of the sample was conducted against 40 healthy (20 ~ 30 year old) women (mean age: 30.5 years) who had not been treated with dermatology since the last 3 months. The area to be measured under the conditions of room temperature 23 ° C and relative humidity 50 to 55% was self-cleansed with the same cleansing product, and each application amount of 0.7 g was applied to the periphery of the ball. Example ⑤ was applied to the same person around the left ball. After 3 hours of application, measurements were made using a Corneometer CM825 (Courage + Khazakaelectr-onicGmaH, Germany). <Unit: AU: Arbitrary Unit>

Before application After application The right ball (Example 1) 40.3 + - 4.44 57.2 ± 7.69 Left ball (Comparative Example 5) 42.3 ± 7.02 34.3 ± 6.02

The Journal of Skin Barrier Research , Vol. 8, Number 1, 68-75 Page, Published by: The Journal of Skin Barrier Research, Title: Device evaluation for skin effect, &Gt;, the measured value is determined to be dry when the ball is in the range of 30 to 49, and when the measured value is in the range of 50 to 59, the skin condition means a moist state having moisturizing power. The higher the measured value of the result value is, the more the moisturizing power is maintained. In the case of before application, the average measurement value of the women participating in the test was 40.3, and it was found that the moisturizing power was increased in the right ball after 3 hours of application of the sample in the right ball. On the other hand, in the case of the left ball coated with the comparative example ⑤, volatile oil volatilizes and volatilizes with the moisturizing material around the ball, and the sample changes to a dry skin state because the sample remains in a hard solid state.

Stability evaluation of formulations

The formulations of the examples and comparative examples were stored at a constant temperature as shown in Tables 7 and 8, and their stability was measured. For the determination of stability, the degree of separation between the oil and the water component was measured. The separation of the oil component and the water component was measured. The separation of the oil component and the water component was measured. However, I was able to confirm this anxiety.
