Abstract

PROBLEM TO BE SOLVED: To obtain a bath preparation, resistant to light and heat and excellent in temporal stability, by making the bath preparation containing sodium chloride and a perfume contain a small quantity of water-soluble ascorbic acid. SOLUTION: This bath preparation is obtained by blending a bath preparation containing preferably 50 to 99wt.% of sodium chloride and preferably 0.5 to 5wt.% of a perfume with 0.01 to 3wt.% of water-soluble ascorbic acid and/or its salt (e.g. ascorbic acid or sodium ascorbate). It shows still higher temporal stability, when preferably 0.1 to 1wt.% of a chelating agent (e.g. edetate) is added to the above essential ingredients.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a bath agent containing sodium chloride as a main component, and more particularly to a bath agent having reduced odor over time, excellent stability, and good usability.

[0002]

2. Description of the Related Art Recently, marine therapy (thalassotherapy) has attracted attention, and cosmetics containing various mineral components have been studied. Bathing agents such as bathing agents containing sodium chloride for the purpose of enhancing the astringent effect are commercially available.

[0003]

However, in the case of a bath agent containing sodium chloride as a main component, perfume may be deteriorated by heat or light during long-term storage, resulting in an unpleasant odor. Therefore, development of a bath agent excellent in long-term stability of quality without impairing the inherent effects of sodium chloride has been desired.

[0004]

Means for Solving the Problems In view of the above-mentioned circumstances, the present inventors have conducted intensive studies and as a result, have found that the problem can be solved by containing a specific component, and have completed the present invention. That is, the present invention provides a bath preparation containing sodium chloride and a fragrance, wherein the bath preparation contains 0.01 to 3% by weight of water-soluble ascorbic acid and / or a salt thereof. A bath agent characterized by containing a chelating agent. The details will be described below.

[0005] The sodium chloride used in the present invention may be either purified or unpurified crude salt or normal salt. The particle size is not particularly limited, and it can be used from a granular material of about 0.5 mm to a granular material of about 5 mm. However, in view of the beauty of a product system, granular sodium chloride of 1 to 5 mm is preferable. The content of sodium chloride is not particularly limited, but is preferably 50 to 99.5% by weight (hereinafter simply referred to as "%"), and more preferably 80 to 99.5%.

As the fragrance used in the present invention, any of natural fragrances and synthetic fragrances can be used as desired. The amount is preferably 0.5 to 5%.

[0007] Examples of the water-soluble ascorbic acid and / or its salt include ascorbic acid, sodium ascorbate,
Ascorbyl magnesium phosphate, disodium ascorbate and the like can be mentioned, and one or more of these can be blended. The amount of the water-soluble ascorbic acid and / or salt thereof is 0.01 to 3%. If it is less than 0.01%, the effect of improving the stability cannot be obtained, and if it exceeds 3%, no remarkable effect corresponding to it is exhibited.

Further, the effect of the present invention becomes more remarkable by blending a chelating agent in addition to the above essential components. Examples of the chelating agent include edetate and hydroxyethanediphosphonic acid, and preferably edetate. The compounding amount is preferably 0.1 to 1%.

In the bath preparation of the present invention, in addition to the above essential components, surfactants, powders, oils, cosmetic ingredients, humectants, preservatives, pigments and the like are used as long as the effects of the present invention are not impaired. be able to.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION The bath preparation of the present invention can be obtained by adding and mixing water-soluble ascorbic acid and / or a salt thereof and other components to sodium chloride, and then adding a fragrance to mix uniformly. . As a method of use, an appropriate amount of the bath agent of the present invention is added to a bath, and the mixture is sufficiently stirred and then bathed.

[0011]

Next, the present invention will be described in more detail with reference to examples, but the present invention is not limited thereto.

Examples 1 to 3 and Comparative Examples 1 and 2 Bath agents having the compositions shown in Table 1 were produced and evaluated for stability.

[0013]

[Table 1]

(Production method) Components 1 to 5 are mixed uniformly,
After adding the component 6, the mixture was thoroughly mixed to obtain a bath agent.

(Evaluation method) Heat resistance test After the manufactured bath agent was allowed to stand in a thermostat at 50 ° C for one month, the degree of odor was evaluated by a panel specializing in fragrance. 2. Light resistance test Environmental test equipment BEC set to an illuminance of 30,000 Lux
After leaving it for 2 weeks on Model II-350 (manufactured by Shimadzu Corporation), the same evaluation was performed. The evaluation criteria for both tests are shown below. A: No change. ：: almost no change. Δ: There is a tendency for slight odor. ×: The odor is clearly changed. The results obtained above are also shown in Table 1.

As is clear from the evaluation results, the examples according to the present invention are more resistant to heat and light, have a reduced degree of unpleasant odor, and are excellent in quality stability as compared with conventional products. It was.

Example 4 Bath agent (jasmine-based) (Component) (%) Sodium chloride 50.0 2. Sodium sulfate 47.2 3. Ascorbyl magnesium phosphate 0.14. Hydroxyethane diphosphonic acid 0.15. Citric acid 1.0 6. Fragrance (jasmine) 1.0

(Preparation method) Components 1 to 5 were uniformly mixed, and after adding Component 6, the mixture was thoroughly mixed to obtain a bath agent. Example 4 had good heat and light resistance, little change in fragrance, and was excellent in quality stability.

Example 5 Bath agent (rose type) (Component) (%) Sodium chloride 80.0 2. Sodium carbonate 5.0 3. Sodium sulfate 6.0 4. Ascorbic acid 3.0 5. 5. Disodium edetate 1.0 Fragrance (Rose series) 5.0

(Preparation method) Components 1 to 5 were uniformly mixed, and after adding Component 6, the mixture was thoroughly mixed to obtain a bath agent. Example 5 was a bath agent which was excellent in quality stability and had little change in rose-based aroma even after long-term storage.

[0021]

As described in detail above, the bath agent of the present invention is resistant to light and heat and has excellent stability over time.
