Description

Detailed Description of the Invention

[0001]

[Industrial application] The present invention spreads creamy foam on the surface of the bath just by adding it to the bath, and you can enjoy the feel of the foam on the surface of the bath while taking a bath, and at the same time, give the skin a moist feeling. A solid bubble bath composition for giving.

[0002]

2. Description of the Related Art Bubble baths are for enjoying the bubbles on the surface of a bath, but conventional bubble bath agents are those that use a stream of water to foam.
If you add a bubble bath agent after pouring hot water, or if you want to take a bath after the second, you need to make bubbles with the water flow from the faucet or shower, and if the water pressure of the tap is weak,
There are problems such as not being able to obtain sufficient bubbles. Further, since the bubble bath agent contains a surfactant, there is a problem that the skin becomes bulky after bathing. In order to solve these problems, a bath agent having a mild action on the skin using a specific surfactant (JP-A-4-346914, JP-A-5-339146), a family bath in the same bath water In consideration of the Japanese custom of entering, bath agents having improved foam retention assuming that several people enter the same hot water (JP-A-3-284619, JP-A-4-210625) and the like have been proposed.
However, it is not sufficient to prevent the skin from becoming bulky after bathing, and neither is designed so that the foam spreads only by adding it to the bath water. Therefore, there has been a demand for a bubble bath composition in which the bubbles on the surface of the bath can be enjoyed just by adding it to the bath and the skin feels moisturized after bathing.

Therefore, an object of the present invention is to spread creamy foam on the surface of the bath just by adding it to the bath, so that you can enjoy the feel of the foam on the surface of the bath while taking a bath, and at the same time, to give the skin a moist feeling. An object is to provide a solid bubble bath composition which gives and smoothes the skin.

It is preferably set to 5.

[0026]

The bubble bath composition of the present invention forms a creamy foam on the surface of the bath just by adding it to the bath, so that it is not necessary to foam with the tap water pressure as in the conventional bubble bath. Therefore, even if the family has already taken a bath, it can easily obtain bubbles that spread on the surface of the bath. Unlike conventional bubble bath agents, the foam that spreads on the surface of the bath is creamy and the feel of the foam is moist. In addition, a moist feeling of the skin after bathing can be obtained.

EXAMPLES Next, the present invention will be described in more detail by way of examples, but the present invention is not limited to these examples.

Examples 1 to 20 and Comparative Examples 1 to 14 (evaluation of spread of bubbles on bath surface, moist feeling after bath): Table 1
~ A bath agent composition having the composition shown in Table 7 was prepared by a conventional method,
The spread of bubbles on the bath surface and the moist feeling of the skin after bath of each bath preparation composition were evaluated according to the following evaluation methods. Comparative Examples 10 to 12 are effervescent bath agents containing a specific surfactant (JP-A-62-234015), and Comparative Examples 13 and 14 are hair detergent compositions containing an emollient agent and a carbon dioxide gas generating component. (Japanese Patent Laid-Open No. 63-135317). The results are shown in Tables 1 to 7.

Dissolve one use of each bath agent composition in 150 liters of bath water (40 ° C., tap water) stretched in a bath (a Japanese-style bath with a bottom area of about 4200 cm ² ), and then bath surface The spread of bubbles on the surface was evaluated according to the following evaluation criteria.

◯: The spread of bubbles is almost the entire bath surface. Δ: The spread of bubbles is half or less of the bath surface. X: Bubbles hardly spread on the bath surface.

Further, hot water after the above bath agent composition was dissolved was used as a test solution, and the moist feeling of the skin after the bath was evaluated. The forearms of 5 panelists were immersed in the test solution for 3 minutes, and the moist feeling of the skin after bathing was evaluated according to the following criteria, and digitized, and the average value of the score of 5 people was evaluated as the moist feeling after bathing. It was used as a score. In addition, if a feeling of dryness or tightness occurred after bathing, the number of people was entered.

[0040]

[Table 7]

Example 1 which is the bubble bath composition of the present invention
All of Nos. 20 to 20 have a good spread of bubbles on the bath surface, and a moist feeling can be obtained after the bath. However, Comparative Example 1 in which the amount of the surfactant was less than 1.5 times the amount of the oily component, Comparative Example 2 in which both the organic acid and the carbonate were not contained in the component, and the total amount of the organic acid and the carbonate was 50. In Comparative Example 3 in which the amount of the surfactant is less than 1% and Comparative Example 4 in which the amount of the surfactant is 1% or less with respect to the bath agent composition, the spread of bubbles on the bath surface is poor. Further, Comparative Example 5 containing less than 0.1% of an essential oily component, Comparative Example 6 containing more than 15% of a surfactant, and Comparative Examples 7 using no particular oily component and other oily components. No. 9 does not give a moist feeling after bathing. Comparative Examples 10 to 12 are different from the present invention in the surfactant and the oily component, so that none of them gives a moist feeling after bathing, but rather feels bulky. Further, in Comparative Example 12, foaming is also insufficient. In addition, Comparative Example 13
Since the amount of the surfactant exceeds 15%, a moist feeling after the bath is not obtained, but rather a bulkiness is felt. In Comparative Example 14, the total amount of the carbonate and the organic acid is less than 50%, so that the spread of bubbles on the surface of the bath is insufficient.

Example 21 Tablets obtained in Examples 3 to 5 (tablet diameter 50 mm, height about 17 mm)
10 mm deep in the center of the tablet, and the volume is 2% of the tablet volume
Are provided. In this tablet, bubbles spread more rapidly than in a normal tablet having no recess. Example 6
A donut-shaped tablet having a tablet diameter of 50 mm, a height of about 19 mm, and a through hole having a diameter of about 17 mm in the central portion was obtained by the prescription of No. 10 to No. 10.
The spread of bubbles in this tablet was faster than that of a normal tablet having no through hole.

Test Example (Evaluation of Bubble Feeling, Moisture Feeling of Skin After Bathing): A conventional bubble bath agent (20 ml of one-time use) which is foamed by water pressure in Comparative Example 15 shown below, and just put in a bath water. With respect to the bubble bath composition of Example 4, the foam feel and the moist feel after bathing were compared.

[0044]

[Table 8]

The bubble bath compositions of Comparative Example 15 and Example 4 were evaluated for use by 32 female panelists. As for the bubble bath agent of Comparative Example 15, the amount used once was put into an empty domestic bathtub, and bubbling was performed while pouring about 150 to 200 liters of hot water. After about 150 to 200 liters of hot water was put into the bathtub, the amount used once was added and bathing was performed. Table 9 shows the evaluation results of the creaminess of each foam, the moist feeling of the foam, and the moist feeling of the skin after bathing.

[0046]

[Table 9]

The bubble bath composition of Example 4 is the same as Comparative Example 15
It can be said that it is superior in both the creaminess of the foam, the moisturizing feel of the foam, and the moisturizing feeling of the skin after bathing, as compared with the above bubble bath agent.
