Description

Transparent gel cosmetic composition

The present application claims priority from Korean Patent Application No. 10-2017-0115330, filed on September 8, 2017, the entire contents of which are incorporated herein by reference.

To a transparent gel cosmetic composition.

As consumers tend to favor natural cosmetics, the development of cosmetics made of natural ingredients, rather than chemical synthesis, is becoming more important. Conventionally, in the development of cosmetics using natural gums, a method of mixing two or more kinds of gums has been used in order to obtain a transparent gel having a high viscosity. However, since the transparent gel having a high viscosity obtained by using such properties has a hard jelly-like form with no flowability, it has a skin-adherence property, and therefore, it is manufactured and used as a hydrogel mask sheet or the like.

Formulations, such as transparent gel sheets, which have been developed to a large extent, have been used in such a manner that they are not absorbed by the skin and are not absorbed by the skin but attached to the skin for 10 to 30 minutes after being attached to the skin. In other words, the hard gel having a high viscosity obtained through the reaction of natural gums has not been used in the form of an emulsion or a serum which is spread uniformly on the face or the skin, because the skin becomes less wettable.

In addition, since a natural gum prepared without a gelling reaction can not form a high viscosity, a high amount of gum must be added in order to form a desired viscosity. However, the higher the content of gum added, the slower the rate of absorption into the skin, and the problem of being pushed out from the surface of the black skin which can not be absorbed.

Therefore, it is required to develop a formulation capable of achieving a moisturizing effect by having a gel phase which can be obtained through a gelation reaction, having an appropriate content of natural gum and high viscosity, yet capable of being absorbed into skin with skin- have.

One aspect is to provide a highly viscous, highly viscous gel cosmetic composition having a viscosity, comprising a mixture of natural gum and a salt dissolved in a solvent and having a viscosity of 3000 cps to 20000 cps, wherein the salt is added to the composition prior to gelation of the natural gum will be.

Another aspect provides a process for preparing a highly viscous, highly viscous, transparent gel cosmetic composition comprising dissolving natural gums and adding a salt prior to completion of gelation of the dissolved natural gums to inhibit gelation .

The natural black moisture impregnation amount is high, and it has a character favorable to moisturizing, and it is made of a material derived from natural materials, and has high stability. However, when the composition is used without processing, its properties are not suitable for use as a cosmetic composition. Therefore, it is necessary to add and process the composition in an appropriate weight portion as described below to adjust the viscosity and spreadability. About 0.01 to about 7.0 weight percent, about 0.01 to about 5.0 weight percent, about 0.01 to 3.0 weight percent, about 0.01 to 2.0 weight percent, about 0.01 to 1.0 weight percent, and about 0.01 to 1.0 weight percent, based on the total weight of the natural black composition, About 0.05 to about 10.0 weight percent, about 0.05 to about 5.0 weight percent, about 0.05 to 3.0 weight percent, about 0.05 to 1.0 weight percent, about 0.1 to 10.0 weight percent, about 0.1 to 7.0 weight percent, about 0.1 to 5.0 weight percent, About 0.1 to 3.0% by weight, about 0.1 to 1.0% by weight, or about 0.5 to 3.0% by weight.

When the salt was added after the gelation reaction was completed, all of the formed gel was broken into a dilute liquid phase. The formulation is diluted to give a gel, but the gel can not be maintained and the viscosity can not be maintained.

Experimental Example  One: The  Branch Visibility perception  Whether or not Example  And Comparative example  Comparative experiment

Examples 1-1 to 1-4 and Comparative Examples 1-1 and 1-2 were prepared as described above. The finished formulation was measured for 1 minute using a Brookfield Rheometer LV DV3T instrument under the conditions of Spindle no. 4, 30 rpm. For the viscosity measurement, samples were stored in a 200ml round-bottomed tube at 1 ° C in a 25 ° C thermostat and then measured.

As a result, it was confirmed that those prepared by the process in which the salt was added before the completion of the gelling reaction were found to have a viscosity and a wettable gel, and that no suitable formulation was formed when no salt was added or after the gelling reaction was completed Respectively.

Ten healthy male and female adults were tested for usability in Examples 1-1, 1-2, 1-3, 1-4, and Comparative Example 1-2 except for Comparative Example 1-1, which had no spreadability . Specifically, after each cosmetic composition was provided, it was applied to the face after cleansing, and then evaluated for spreading, absorption rate and stickiness after use according to the following criteria, and the results are shown in Table 4 below.

Among the above criteria, wetting and absorption rate are characteristic of formulations having viscosities, and there is a difference in feeling depending on the absorption rate depending on the viscosity of the gel formulation forming the viscosity, and a sticky residue is often left as it is absorbed slowly. This can be an important feature to judge the quality of finished products.

Experimental Example 3: Reduction of skin temperature and evaluation of persistence by moisture absorption

In order to confirm whether or not water supply and skin absorption effect according to the use of natural gums occurred, skin temperature reduction and sustainability evaluation were carried out for Examples 1-4 and Comparative Example 1-2.

Specifically, the skin temperature of the test site (5 × 5 cm 2 in the inner part of the humpback) was photographed with an infrared camera to five healthy adults (mean age 28.6 years). After that, 50 μl of the product was applied uniformly to the test site, absorbed, and then taken again with an infrared camera for 10 minutes at 1 minute intervals. The measuring device was IRIS-X P (GOLD) (MEDICORE, Korea).

The duration was measured by the temperature of the images, and the standard deviation of the measurement values was set, and the duration of each subject was checked to calculate the average duration. The rate of temperature change was calculated by using the pre-application value and the measured value of each subject, and then the total change rate was calculated by the average value of 5 persons.

efficacy	Examples 1-4	Comparative Example 1-2
