Description: TECHNICAL FIELD The present invention relates to a gel-like skin cosmetic having a skin whitening effect, a moisturizing effect, and a high quality stability. [0002] L-ascorbic acid is widely known as a substance having a whitening effect, having an effect of suppressing the production of melanin, a bleaching action of the produced melanin, etc., but has a very high stability. The whitening effect is not always sufficient because of the poor quality. [0003] In order to improve the stability of L-ascorbic acid, various L-ascorbic acid derivatives have been developed. In recent years, L-ascorbic acid-2-phosphate, L-ascorbic acid phosphate and L-ascorbic acid 2-phosphate have been developed.
Inorganic acid esters of L-ascorbic acid such as ascorbic acid-2-sulfate have been used in skin cosmetics (JP-A-3-109308, JP-A-3-275610). [0004] On the other hand, water-soluble polymers have high water retention, and are therefore added to cosmetics for the purpose of enhancing the moisturizing effect. In addition, it is used to improve the stability of the emulsion and to create a unique and unique dosage form by utilizing its viscosity characteristics. [0005] Water-soluble polymers are incorporated into skin cosmetics containing L-ascorbic acids for the purpose of improving stability (JP-A-60-116618 and JP-A-4-77).
409). However, detailed investigation revealed that the viscosity stability and the moisturizing effect were not always sufficient. An object of the present invention is to provide a gel-like skin cosmetic having a whitening effect, a high moisturizing effect, and excellent stability. Means for Solving the Problems The present inventors have made intensive studies in view of such circumstances, and as a result, the following skin cosmetics
Surprisingly, the synergistic effect brings an excellent moisturizing effect to the skin, and it is a gel having a viscosity suitable for application to the skin, and also found to be excellent in quality and stability. The present invention has been completed. That is, the present invention comprises the following components (A) an inorganic acid ester salt of L-ascorbic acid, and (B) at least two members selected from the group consisting of xanthan gum, potato starch, gellan gum, and tragacanth gum. It is a gel-like skin cosmetic. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described below in detail. The inorganic acid ester salts of L-ascorbic acid used in the present invention include L-ascorbyl-2-sodium phosphate, L-ascorbyl-2-magnesium phosphate, L-ascorbyl-2-potassium phosphate, L-ascorbyl -2-Calcium phosphate, L-ascorbyl-
2-sodium sulfate, L-ascorbyl-2-magnesium sulfate, L-ascorbyl-2-potassium sulfate and L
-Ascorbyl-2-calcium sulfate and the like, but are not limited thereto. These inorganic acid ester salts of L-ascorbic acid may be used alone or in combination of two or more. Among the inorganic acid ester salts of L-ascorbic acid, particularly preferable results are obtained when L-ascorbyl-2-magnesium phosphate is added to the cosmetic together with the component (B). The amount of the inorganic acid ester salt of L-ascorbic acid in the cosmetic is 0.001 to 10% of the total amount of the cosmetic.
% By mass, and more preferably 0.01 to 5% by mass.
It is. If the amount is less than 0.001% by mass, it is difficult to obtain a whitening effect, and if it exceeds 10% by mass, discoloration, discoloration and precipitation are liable to occur. (B) Xanthan gum, potato starch, gellan gum, tragacanth gum used in the present invention
Of the total amount of the cosmetic is 0.1 to 1
0 mass% is preferable, and more preferably 0.5 to 5 mass%.
It is. If it is less than 0.1% by mass, the viscosity is low and 10% by mass.
It is not preferable that the ratio exceeds the above, since the surface is inferior in terms of stickiness and the like. In the cosmetic of the present invention, in addition to the above-mentioned raw materials, a dye, a fragrance, a preservative, a surfactant, a pigment, an antioxidant and the like are appropriately compounded within a range for achieving the object of the present invention. Can be. [0014] Examples of the dosage form of the cosmetic of the present invention include creams, milky lotions, serums, packs, and cosmetics.
For example, in the case of an emulsion or the like, this cosmetic can be manufactured by a usual method of emulsifying and dispersing an oil phase and an aqueous phase which are each dissolved by heating and cooling. EXAMPLES The present invention will be described below in detail based on examples and comparative examples. The storage stability test method and sensory test described in the examples are as follows. (1) Storage stability test method Samples were placed in a constant temperature bath at 40 ° C., observed over time, and evaluated according to the criteria shown in Table 1. [Table 1] Here, “abnormal” means a phenomenon in which discoloration and odor occur and precipitation occurs. (2) Sensory test After 20 consecutive subjects used the sample for 14 days, the characteristics of the sample were evaluated. For the test items such as wettability and affinity, 16 or more respondents who answered "moisture on the skin" or "good affinity to the skin and low stickiness" were ○, 15 10 to 10 were evaluated as △, and 9 or less were evaluated as x. (3) Viscosity The sample is gel-like and has an appropriate hardness. ○, when the viscosity of the gel-like skin cosmetic is too low or too hard to apply to the skin. Was evaluated as x. Examples 1 to 4 and Comparative Examples 1 to 5 (A) L-ascorbic acid inorganic acid ester salt, (B)
Xanthan gum, potato starch, gellan gum, and tragacanth were blended in the compositions shown in Tables 2, 3 and 4, and a gel-like serum was prepared based on the following preparation method. Each of the above tests was performed for each, and the results are shown in Table 5. [Table 2] [Table 3] [Table 4] [Table 5] (Preparation method) (A) is uniformly dissolved at 70 ° C., and cooled to a temperature of 30 ° C., and then (B), which is uniformly dissolved at room temperature, is poured, stirred and prepared. (Characteristics) The serums of Examples 1 to 4 of the present invention showed remarkable effects in various characteristics. On the other hand, the serums of Comparative Examples 1 to 5 were inferior in various properties as compared with the examples of the present invention. Examples 5 to 8 The creams of the present invention having the compositions shown in Tables 6 and 7 were prepared by the following methods. [Table 6] [Table 7] (Preparation method) (B) is heated and dissolved at 70-80 ° C., (C) is uniformly dissolved at 70 ° C., and (C) is poured into (B) while stirring (B) to emulsify. After dispersing, the mixture is cooled to 30 ° C. while stirring, and (A) uniformly dissolved at room temperature is added to prepare. (Properties) The creams of Examples 5 to 8 showed good results in all the above tests. Examples 9 to 12 Emulsions of the present invention were prepared according to the compositions shown in Tables 8 and 9 by the following method. [Table 8] [Table 9] (Preparation method) (B) is heated and dissolved at 70-80 ° C., (C) is uniformly dissolved at 70 ° C., and (C) is poured into (B) while stirring (B) and emulsified. After the dispersion, the mixture is cooled to 30 ° C. while stirring, and (A) uniformly dissolved at room temperature is added to prepare.
