Two-component formulation in which the two contents are separated and supported inside one container, and then mixed with the two contents by shaking the container immediately before use, so that the potent ingredient can be discharged in a uniformly dispersed or dissolved state. Cosmetics are becoming more and more popular.

As the two-component formulation cosmetics, like the two-layer separable cosmetics of Korean Patent Application Publication No. 10-2012-0090943, the mixture is divided into oil layers and water layers having different properties and densities before mixing.

Another two-component cosmetic composition is a two-component formulation in which the two different formulations are physically separated due to the structure of the container having a dividing wall, and when the operation is performed on the container, the two formulations are mixed while the dividing wall is removed. There is cosmetics. If the former uses two-liquid separation due to different chemical properties between the two formulations, the latter is different in that they physically separate the two formulations.

Accordingly, the present inventors have diligently tried to find a way to make mixing easier when the two formulations, which are physically separated due to the special structure of the container, such as the latter, are mixed with each other due to the removal of the separation wall. , The first and second formulations contain a metal ion sequestrant, a polyol, and a solvent, respectively, and vary the type and content of the thickener contained in the first and second formulations, By adjusting the viscosity or adjusting the mixing ratio of the first formulation and the second formulation, it was found that the ease of mixing appears different.

[ Test Example  3] Stabilization effect test of potency ingredient

As a method for stabilizing ethyl ascorbyl ether (EAE) (whitening agent) having excellent whitening efficacy for long-term activity, a method of keeping the pH lower than 5 is known. However, when supporting a high content of 10% by weight or more based on the total weight of the composition, even if the pH is lower than 5, EAE is difficult to stabilize and discolor (FIG. 1). To solve this problem, 1,3-butylene glycol (1,3-butylene glycol), 1,2-propanediol (1,2-propandiol; using Fermandiol ^® ), DPG as shown in Table 5 below (Dipropylene Glycol), ethanol, glycerin, etc. in each solvent was prepared a composition containing 10% by weight of COS-VCE-K (ethyl ascorbyl ether; EAE) to test the stability of each.

1,3-butylene glycol	90	-	-	-	-
1,2-propanediol	-	90	-	-	-
DPG	-	-	90	-	-
ethanol	-	-	-	90	-
glycerin	-	-	-	-	90
EAE	10	10	10	10	10

Solubility	Good	Good	Insoluble	Good	Insoluble
Viscosity (cps)	240cps	No viscosity	220 cps	No viscosity	1095cps

As a result, as shown in Table 5, EAE is not only well dissolved when anhydrous-formulated using a large amount of volatile solvents such as 1,3-butylene glycol, 1,2-propanediol, ethanol, and the like, As shown in FIG. 2, even if EAE is contained in the composition of # 7 (or # 8) of Table 5 in an amount of 10 wt% or more based on the total weight of the composition, the stability of EAE is maintained at various temperature ranges so that the composition does not discolor. It was confirmed.

In addition, as a result of measuring the viscosity of the samples # 7 to # 11, it was found that most of the sample is 1,000 cps or less, it was found that the viscosity is similar to the samples # 1 to # 3. Therefore, after any one of the samples # 7 to # 11 as the first formulation, and the sample having a viscosity of 10,000 cps or less as the second formulation, the weight ratio of the first formulation and the second formulation is 1: 1 or 10: Formulated to be 1; Alternatively, a sample having a viscosity of 6,000 cps or less is used as the first formulation, and any one of Samples # 7 to # 11 is used as the second formulation, and then blended so that the weight ratio of the first formulation and the second formulation is 10: 1. In this case, it was predicted that mixing would be easy when shaken.

The specific parts of the present invention have been described in detail above, and it is apparent to those skilled in the art that such specific descriptions are merely preferred embodiments, and thus the scope of the present invention is not limited thereto. something to do. Thus, the substantial scope of the present invention will be defined by the appended claims and their equivalents.
