The present invention relates to a bath composition having an excellent effect and an excellent cleaning action.

[0002]

Conventionally, sodium hydrogencarbonate, sodium sulfate, sodium chloride, etc. have been used in order to increase the moisturizing effect when taking a bath, but they are satisfactory in terms of skin-beautifying effect and cleaning action. I couldn't do it.

Therefore, the present inventor conducted extensive studies in view of the above circumstances, and as a result, D. When S-M is used as a bath agent,
It has been confirmed that the skin has excellent moisturizing (moistening), flexibility (smoothness), elasticity (tension), and beautiful skin effect that can impart gloss, and also has a skin cleansing action by antibacterial action against indigenous bacteria. Then, the present invention was completed.

[0004]

The object of the present invention is to provide a composition excellent in skin beautifying action (effect of improving rough skin, finely textured, improved color and gloss, improved tension, etc.) and skin cleansing effect. To provide.

The present invention is a bath composition containing Dead Sea water or a salt thereof.

The component used in the present invention is Dead Sea seawater or a salt thereof. The Dead Sea is a salt lake about 100km inland from the Mediterranean coast of West Asia. It occupies the lowest part of the Jordan Fault Valley, and the lake surface is 397 above the Mediterranean water surface.
m lowest, the lowest on earth. A lake with a length of about 81.6 km, a width of about 17.6 km, a maximum depth of 399 m, an average depth of 146 m, and a surface area of 1020 km ² has a high salt content and a concentration of about 5 times that of seawater. The salinity of the Dead Sea's seawater (DS) varies depending on the state of seasonal rainfall because the Dead Sea is as wide and not as deep as the ocean. Dead Sea Salt (DSM) used here
The composition of is as follows. MgCl ₂ 24.12 to 29.48% KCl 49.83 to 60.86% NaCl 14.34 to 17.52% CaCl ₂ 0.99 to 1.22% Dead Sea salt is a non-uniform crystal and white powder. Almost soluble in odorless water Approximate solubility = 6.0 in 100 ml of water (20 ° C)
A small amount of insoluble matter remains at g. The pH of the solution is 7.0
Is 8.0

D. to be incorporated in the bath composition of the present invention. S-
M beautifies the stratum corneum and enhances skin function, restores or improves the function originally possessed by the skin to maintain the skin in a healthy state, and particularly when applied to aged skin, a remarkable effect is exhibited. .

D. When S-M is used, it may be added in any amount, but preferably 10 wt% or more.

In the present invention, D. As the other component to be blended with S-M, a commonly used bath base can be used. If necessary, the following components can be appropriately selected. 1) Inorganic salts Sodium chloride, sodium hydrogen carbonate, sodium carbonate, boric acid, borax, sodium sulfate, potassium sulfide,
Sodium thiosulfate, calcium hydrogen phosphate, potassium chloride, ammonium chloride, sodium phosphate, sodium sesquicarbonate and the like. 2) Inorganic acids Silicic anhydride, metasilicic acid, etc. 3) Organic acids Citric acid, tartaric acid, malic acid, etc. 4) Fats and oils Olive oil, soybean oil, almond oil, castor oil, coconut oil, palm oil, turtle oil, nuka oil, jojoba oil, mink oil, egg yolk oil, squalane, avocado oil, lanolin, liquid paraffin, white petrolatum and the like. 5) Binders Carboxymethylcellulose sodium, methylcellulose, sodium salt, casein, pectin, starch,
Sodium alginate, polyvinyl alcohol, polyvinylpyrrolidone, etc. 6) Polyhydric alcohols Glycerin, propylene glycol, sorbitol, polyethylene glycol 1, 3-butylene glycol and the like. 7) Fragrances Lavender oil, jasmine oil, rose oil, lemon oil, orange oil, peppermint oil, ginger oil, fennel oil, cedar oil, hiba oil, cypress oil, rose oil, eucalyptus oil, camphor, peppermint oil, spearmint oil , Geraniol,

EXAMPLES The present invention will now be described in detail with reference to examples, but the present invention is not limited thereto. Examples 1 to 5 and Comparative Example 1 A D. Various tests were carried out by adjusting each bath composition containing SM as described in Table 1.

[Table 1]

The bath was filled with hot water of about 200 liters at 39 ° C., 30 g of the bath composition of the present invention was put therein, and the mixture was stirred and uniformly dissolved. For the evaluation method, the skin condition after continuous use once a day for 4 weeks was examined for 20 people, and the evaluation was made based on the number of people who confirmed the rough skin improving effect. In addition, a sensory test was conducted in the same manner as described above to examine the number of people who recognized a wetting action.

[0012]

[Table 2]

As is clear from Table 2, both the rough skin improving effect and the sensory test were higher than those of the comparative examples. The examples in which SM was compounded showed excellent results.

[0014]

[Table 3]

The evaluation was performed according to the bathing method shown in Table 2, and after continuous use, each evaluation item was evaluated on a scale of 5; 5 points were "very good", 4 points were "good", and 3 points were "normal". , "No change" was given 2 points, and "bad" was given 1 point, and the average value was taken.
The results are shown in Table 4.

[0016]

[Table 4]

As is clear from Table 4, Examples 7 and 8 which are the bath compositions of the present invention are superior to Comparative Example 2 in all items. That is, the bath composition of the present invention is excellent in the skin beautifying effect and the skin cleansing effect.

Escherichia coli is cultivated in a broth agar medium and made into a petri dish to be solidified, and a sterile mouth paper having a diameter of 1 cm is placed thereon. Drop 0.5 ml of the sample on the paper by the conventional method,
The culture was incubated at 37 ° C. for 48 hours, and the antibacterial activity was tested by the size of inhibition. The indication "+" means that there is antibacterial activity, and "±" means that there is antibacterial activity. As a sample, each bath composition was dissolved in sterile water. The results are shown in Table 5.

[0019]

[Table 5]

As is clear from Table 5, the bath compositions 7 and 8 of the present invention clearly have antibacterial activity against E. coli. In addition, the same test was carried out on Staphylococcus aureus to confirm the antibacterial activity. This proves that the bath composition of the present invention has a cleansing effect on the skin from the viewpoint of microorganisms.

[0021]

As described above, it is obvious that the present invention provides a useful bath composition having wettability, softness, elasticity, and color luster, that is, a beautiful skin effect and a cleansing effect. is there.
