DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for preventing scattering of a dye incorporated in a bath water so as to prevent the dye contained therein from scattering around.

[0002]

2. Description of the Related Art One of the conventionally known bathing agents is of a powder type. This type of bath additive
It is contained in a container such as a can, and the user puts a necessary amount into the bath water as needed. Also, a bag is filled with a single amount, and may be opened and put in each use. This type of bath has the advantage that the user can adjust the amount of use according to his preference or can dissolve it quickly, but at the time of putting in, the powder scatters in the bathtub and surrounding wall, and has the drawback of polluting the surroundings. there were. Almost no studies have been made on techniques for improving the inconvenience due to such scattering, and for example, in a bath preparation composition containing milk powder, an alkali substance and an organic acid, or a mixture of these with a silicic anhydride. It is only known that mixing can prevent the powdered milk from scattering or adhering to the bath.

[0003]

As described above, the technique for improving the inconvenience in introducing the bath agent is not yet sufficient. No measures have been taken to prevent scattering. Therefore, an object of the present invention is to provide a means for preventing scattering of a dye when a bathing agent, particularly a powdered bathing agent is poured into bath water.

[0004]

Means for Solving the Problems As a result of intensive studies to solve the above-mentioned problems, the present inventors have found that by mixing an effective amount of an amphiphilic substance with a bathing agent containing a dye, the scattering of the dye can be achieved. Have been found to be able to be effectively prevented, and the present invention has been achieved. The present invention has solved the above-mentioned problems by the following means. (1) A method for preventing scattering of a dye, which comprises mixing an effective amount of an amphipathic substance with a bathing agent containing a dye. (2) The method of (1), wherein the amphiphilic substance is polyethylene glycol. (3) The method of (1) or (2), wherein the bathing agent is in a powdery or granular form.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION The amphiphilic substance used in the present invention is a molecule having both a hydrophilic part and a hydrophobic part in one molecule, or a substance having an amphipathic effect, and is a bath agent component.

% By weight, preferably 0.1 to 3.0% by weight, but the value varies depending on the substance and cannot be said unambiguously. Here, the term “effective amount” is used because the effective amount of addition may vary depending on the substance. It is not preferable to mix a large amount in the preparation, because other components may be insufficient or the fluidity may be deteriorated, resulting in inconvenience at the time of production.

The bathing agent which can be applied to the present invention includes, in addition to the conventionally known powdery type, a granular type, a granular type and a solid type, and is prepared by appropriately combining the following exemplified components.

EXAMPLES The present invention will be specifically described below with reference to examples, but the present invention is not limited to these examples. Example 1 The effect of the method for preventing scattering of a dye of the present invention was examined by the following method. The size is height 60 x width 100 x depth 50 cm, almost at the center of the surface of the bath in which 200 liters of hot water is put, from a height of 30 cm above,
Powdery samples A to E (30 g each) having the composition shown in Table 1 were charged. The average particle size of Samples A to E was about 200 μm. In advance, wet filter paper (diameter: 50 mm) is applied to the eight peripheral walls of the bathtub so that the upper end of the filter paper becomes the upper end of the bathtub, and the state of adhesion of the dye to each filter paper is evaluated according to the following evaluation criteria. In addition, it was visually confirmed. However, for each of the three filter papers to be attached to the lateral peripheral wall, the filter papers were arranged such that the intervals between them were equal. In this case, the position of the bath surface in the bathtub is about 16 cm from the upper end of the bathtub.

(Evaluation criteria) The results are shown in FIG. 1 with ×, Δ, and ○ indicating the condition of the filter paper at eight locations for each preparation. FIG. 1 is a plan view of the bathtub, in which symbols indicating the condition of the filter paper are attached to the positions of the filter paper attached to the inner peripheral wall. As is clear from FIG. 1, in Sample A containing no amphipathic substance (here, polyethylene glycol was used), the dye was noticeably attached to the filter paper. On the other hand, in Samples B to E containing the amphipathic substance, the scattering of the dye was clearly smaller than that of A, and the prevention of the scattering of the dye was confirmed.

According to the present invention, an effective amount of an amphipathic substance is blended with a bath containing a pigment so that the blended pigment does not scatter around when it is poured into bath water. can do. As a result, unnecessary coloring by the pigment on the bathtub, its peripheral wall, and floor can be effectively prevented. Especially in the bathroom, not only the peripheral wall and the floor, but also the bath tub are often tiled, and the joints of the tile are easily colored by the pigment, but when the bath additive of the present invention is used, it is possible to reduce those colorings. it can.
