Various antibacterial agents and the like are compounded for the purpose of preservation, and it has been proposed to use cocoylarginine ethyl ester pyrrolidonecarboxylate as an antibacterial agent with little irritation to the skin (Japanese Patent Publication No. 47-313). Then, in order to supplement the antibacterial properties of cocoylarginine ethyl ester pyrrolidonecarboxylate, in addition to cocoylarginine ethylesterpyrrolidonecarboxylate, cetylpyridinium chloride,
It is also known to add parabens as antibacterial agents. However, when parabens are used, since the solubility of paraben itself is low, there is a problem in storage stability such that the aqueous solution becomes cloudy or precipitates are generated. Therefore, in order to improve the solubility of parabens, polyols such as propylene glycol and 1,3-butylene glycol have been added. However, when using these polyols to dissolve parabens, it is necessary to mix them in large amounts, and although the solubility of parabens can be improved, they are applied to the skin as a lotion. In case,
There was a problem of feeling slimy and sticky. SUMMARY OF THE INVENTION [0004] An object of the present invention is to provide a skin lotion having good skin feel, excellent storage stability and antibacterial properties. The present inventors have conducted intensive studies to solve the above-mentioned problems, and as a result, have found that a specific lotion solves the above-mentioned problems, and have completed the present invention. Reached. That is, the present invention provides at least one selected from the group consisting of (A) cocoylarginine ethyl ester pyrrolidone carboxylate, (B) cetylpyridinium chloride, and (C) benzoic acid and its salts, sorbic acid and its salts.
A lotion characterized by containing a seed. DETAILED DESCRIPTION OF THE INVENTION The cocoyl arginine ethyl ester pyrrolidone carboxylate used in the present invention is obtained by N-acylation of arginine with coconut oil fatty acid.
Ethyl esterified product is neutralized with pyrrolidone carboxylic acid, and a product commercially available from Ajinomoto Co., Inc. can be used (trade name "CAE"). The amount of the cocoyl arginine ethyl ester pyrrolidone carboxylate is not particularly limited as long as the effects of the present invention can be obtained. Is 0.01 ~
It is used in an amount of 0.5% by weight, more preferably 0.03 to 0.1%. Next, the cetylpyridinium chloride used in the present invention is not particularly limited, and those usually used in cosmetics can be used. The amount of cetylpyridinium chloride is not particularly limited as long as the effects of the present invention can be obtained.
It is used in the range of 01 to 1% by weight, preferably 0.001 to 0.5% by weight, more preferably 0.005 to 0.1%. The benzoic acid and salts thereof and sorbic acid and salts thereof used in the present invention are not particularly limited, and those usually used in cosmetics can be used. These can be used in the form of a free acid or in the form of a salt, but from the viewpoint of solubility, the form of a salt is preferable. Salts include sodium salts, potassium salts,
Examples thereof include a calcium salt and a magnesium salt, and a sodium salt and a potassium salt are preferable from the viewpoint of solubility. Specific examples include sodium benzoate and potassium sorbate. Of these, benzoic acid and salts thereof, and sorbic acid and salts thereof may be used alone or in a mixture thereof. The amount of benzoic acid and its salt, sorbic acid and its salt is not particularly limited as long as the effects of the present invention can be obtained.
001 to 5% by weight, preferably 0.001 to 1% by weight,
More preferably, it is used in the range of 0.05 to 0.5%. [0012] To the lotion of the present invention, as long as the effects of the present invention are not impaired, other components commonly used in lotions can be blended as other components. For example, increasing the active ingredients such as surfactants, humectants, emollients, pH adjusters, fragrances, antioxidants, chelating agents, plant extracts, anti-fading agents, anti-inflammatory agents, skin activators, astringents, etc. Can be. As the above-mentioned other components, polyols such as propylene glycol, dipropylene glycol and 1,3-butylene glycol can also be blended. However, when a large amount of these polyols is blended as described above, the touch to the skin may become heavy, so it is preferable to use the polyol in a blending amount of 5% by weight or less based on the total amount of the composition. The lotion of the present invention is prepared by dissolving cocoylarginine ethyl ester pyrrolidonecarboxylate, cetylpyridinium chloride, benzoic acid and its salts, sorbic acid and its salts in water or purified water, and, if necessary, It can be produced by a conventional method by further mixing other components used in the lotion. Hereinafter, the present invention will be described with reference to examples, but the present invention is not limited to the examples. Examples 1 to 6 According to the compositions shown in Table 1,
Each component was dissolved in purified water to produce the lotion of the present invention. In addition, antibacterial tests were performed on the lotions of Examples 1 to 6, and it was confirmed that the lotions exhibited good antibacterial properties. [Table 1] <Evaluation of Storage Stability> The storage stability was evaluated according to the following criteria by visually observing the dissolved state of the lotion obtained in Examples 1 to 6 at 0 ° C. for one week. Was evaluated. The results are shown in Table 1. ○ Transparently dissolved. × There is cloudiness or precipitate. Table 1 shows that the lotion of the present invention has good storage stability. <Evaluation of Feeling on Skin> The feeling on the skin was determined by impregnating the skin with the lotion obtained in Examples 1 to 6 and using it in a usual manner. , Sliminess, and stickiness were evaluated.
The results are shown in Table 1. Table 1 shows that the lotion of the present invention has a good feel. <Examples 7 to 10: Preparation of lotion> A lotion was prepared according to the formulation shown in Table 2. The obtained lotion is
Good storage stability and feel were exhibited. [Table 2] According to the present invention, it is possible to provide an antibacterial lotion having good storage stability and good skin feel.
