Therefore, the scope of the invention is defined by the scope of the appended claims and their equivalents. Dosage form

In order to find a method capable of improving the ease of mixing of the two-liquid dosage form composition of the present invention, first, six kinds of samples (#1 to 6) each having the composition shown in Table 1 below were prepared, and these samples were designed to gradually increase in viscosity. As a solvent of purified water, edetate disodium was used as the metal ion capturing agent, the butylene glycol and glycerin as a polyhydric alcohol, a xanthan gum used as a thickener, and a carbomer carbopol 981 ^® FG700 ^®, and acrylates / C10-30 alkyl acrylate cross-linked polymer ETD2020 ^®, the viscosity of each sample using a viscometer (vISCOMETER (BROOKFIELD DV-II + Pro)) was measured. Table 1 Test Example 1: Judging the ease of mixing when the first dosage form and the second dosage form were formulated in a weight ratio of 1:1

First, as shown in the following Table 2, one of the samples #1 to #6 prepared in the dosage form is used as the first dosage form (one dose), and one of the samples #1 to #6 is used as the second dosage form ( After combining the amounts of all possible cases of the two doses, the first dosage form and the second dosage form are formulated in a weight ratio of 1:1.

As shown in Table 3 below, after setting the criteria for ease of mixing, the container containing the solution of the first dosage form and the second dosage form was gently shaken by hand (manually mixed) to mix the first dosage form and the second dosage form. In the case where the general customer (female, 20 to 50 years old) is used as a standard, when the prepared solution is uniformly mixed for more than 10 times, it is judged that the ease of mixing is poor, and it is not suitable for commercialization. Table 2 table 3

As a result, as shown in the above Table 2, the viscosity of the first dosage form is 3,000 cps or less as in the samples #1 to #4, and the viscosity of the second dosage form is 10000 cps or less as in the samples #1 to #6, in any case. It's easy to mix. In particular, when the viscosity of the first dosage form is 1000 cps or less and the viscosity of the second dosage form is 10000 cps or less, the number of mixing is 5 or less, which shows excellent ease of mixing. Test Example 2: Judging the ease of mixing when the first dosage form and the second dosage form were formulated in a weight ratio of 10:1

As in Test Example 1, first, one of the samples #1 to #6 prepared in the dosage form was used as the first dosage form (one dose) and one of the samples #1 to #6 as shown in Table 4 below. After combining the amounts of all possible cases of the second dosage form (two doses), the first dosage form and the second dosage form are formulated in a weight ratio of 10:1.

Thereafter, the container containing the solution for preparing the first dosage form and the second dosage form is shaken by hand (manually mixed) to mix the first dosage form and the second dosage form. The criteria for the ease of mixing were as in Test Example 1, and judged by the criteria of Table 3 above. Table 4

As a result, as shown in the above Table 4, when the viscosity of the first dosage form is 1000 cps or less as in the samples #1 to #3, and the viscosity of the second dosage form is 10000 cps or less as in the samples #1 to #6, It is easy to mix in any situation. Further, in the case where the viscosity of the first dosage form is 1000 cps to 6000 cps as in the samples #4 to #5, and the viscosity of the second dosage form is 3000 cps or less as in the samples #1 to #4, it is easy to mix.

In particular, when the viscosity of the first dosage form is 1000 cps or less and the viscosity of the second dosage form is 6000 cps or less, the viscosity of the first dosage form is 1000 cps to 3000 cps, and the viscosity of the second dosage form is 500 cps to 1000 cps, the mixing times are 5 times or less. , showing excellent ease of mixing. Test Example 3: Stabilization effect test of efficacy component

As a method of stabilizing ethyl ascorbyl ether (EAE) having excellent whitening effect and maintaining activity for a long period of time, a known method is to maintain the pH to 5 or less. However, when a high content of 10% by weight or more based on the total weight of the composition is contained, even if the pH is 5 or less, EAE is difficult to be stabilized, and there is a problem of discoloration (Fig. 1). In order to solve such a problem, as shown in Table 5 below, a composition was prepared, that is, 1,3-butylene glycol, 1,2-propanediol (1,2-propandiol). The solvent was used to contain 10% by weight of COS-VCE-K (ethyl ascorbyl ether; EAE) in each solvent such as Fermandiol ^® , DPG (Dipropylene Glycol), ethanol, glycerin, etc., and the respective stability was tested. table 5

As a result, as shown in the above Table 5, when a volatile solvent such as 1,3-butanediol, 1,2-propanediol or ethanol is used in a large amount as a solvent, it is confirmed that it is easy to dissolve EAE even when it is anhydrous. As shown in Fig. 2, even when the content of EAE is 10% by weight or more based on the total weight of the composition in the composition of #7 (or #8) of Table 5, the stability of EAE can be maintained in various temperature ranges. Does not cause discoloration of the composition.

Further, the results of measuring the viscosity of the samples #7 to #11 were mostly shown to be 1000 cps or less, and it was found that the viscosity of the samples #1 to #3 was similar. Therefore, when one of the samples #7 to #11 is used as the first dosage form and the sample having a viscosity of 10000 cps or less is used as the second dosage form, the weight ratio of the first dosage form to the second dosage form is 1:1 or 10 :1 in the case of preparation; or, the sample having a viscosity of 6000 cps or less is the first dosage form, and after one of the samples #7 to #11 is the second dosage form, the weight ratio of the first dosage form to the second dosage form is 10: 1 In the case of preparation, it is predicted that mixing is easy.
