The present invention relates to a solution such as a shampoo.
Shampoos, rinses, and conditioners are used for hair (or head) care (washing).
The solution is put in a container body of, for example, a pump device (e.g., a shampoo container). Pushing of a head of the pump device makes the solution in the container body come out through a nozzle outlet. The solution comes out in the form of a lather. At the time, a user could not recognize a color of the lather with the naked eye.
Upon washing one's hair, adults do not care about a color of lather of a shampoo coming out from a pump device.
Many children (infants) often hate hair washing. In such an occasion, if a lather of a shampoo solution has a color, even the children (infants) disliking the hair washing would be able to enjoy it.
From the aspect, a trial was made to add a coloring material (dye) to the conventional shampoo solution.
Even though an enough amount of coloring material (dye) was added, a color of lather could not be recognized with the naked eye.
In view of the above, to solve the above problem, the present invention provides a solution for making a lather of which color can be clearly recognized with the naked eye upon, for example, hair washing (or playing).
The inventor conducted research and development to unravel why no color could be visually recognized from the lather made of the shampoo solution containing the enough amount of coloring material (dye).
In the repeated trial and error, a lather having a deep color (which can be clearly recognized with the naked eye) was incidentally produced.
At the time, the inventor did not know (the reason) why the lather made of the shampoo solution had the deep color.
The inventor could not specify which lather made of which shampoo solution (shampoo solution how it was produced) had the deep color.
The shampoo solution should have been produced by following the same process as it has been done, though. The inventor could not unravel why the lather made of the shampoo solution had the deep color.
The inventor recalled his memory one by one about the process how the shampoo solution was produced.
Finally, he reminded that the solution which made the deep colored lather was produced through a step of inputting a surfactant (frothing agent) into a dye-containing solution (solution made by mixing a dye and water).
Before the above step, the inventor input the coloring material (dye) and the surfactant together into water at the same time (at once). This is the typical way in mixing procedure.
The inventor did not know why such a difference occurred when changing the order of adding the materials in the mixing (adding) step.
However, it surely happened that the lather having the deep color could be obtained as a result of changing the order of adding the materials in the mixing (adding) step.
In view of the above, the inventor tried to add a dye into a surfactant-containing solution which was made by mixing a surfactant and water. As a matter of course, the same type and the same amount of surfactant and dye as used in the above case were employed. In this case, however, the lather having the deep color as being obtained in the above case could not be achieved.
Results were the same even when a type of surfactant and/or dye were changed, or even when an amount of surfactant and/or dye were changed.
The inventor studied again by putting such results together.
As a result, the inventor came to have an idea as described below.
Initially, the inventor studied it case by case, i.e., a case where a surfactant, a dye, etc., together were added to water at the same time, a case where a dye was added to a surfactant-containing aqueous solution, and a case where a surfactant was added to a dye-containing aqueous solution, for the purpose of unraveling why color concentrations of lathers made of those solutions were different from each other.
As a result, the inventor came to have the following idea.
When a coloring material is added to water, a hydrogen bonding occurs between the coloring material and the water. Thereafter, even if a surfactant is added thercto, a bonding (reaction) hardly occurs between the coloring material (whose hand for bonding (reacting) is occupied by the hydrogen bond) and the surfactant. In view of the above, it was so estimated that the surfactant could effectively work as a frothing agent. Also, it was so estimated that the coloring material could effectively work as a coloring material (development of a color: coloration).
In the case where a surfactant, a coloring material, etc., together are added to water at the same time, a bonding (physical bond or chemical bond) occurs between the surfactant and the coloring material. Therefore, it was so estimated that this lowered the function of the surfactant as a surfactant (a frothing agent). It was so estimated that this lowered the function of the coloring material as a coloring material (development of a color: coloration).
It was so estimated that the case where a dye was added to a surfactant-containing aqueous solution resulted in also the same result as the case where a surfactant, a dye, etc., together were added to water at the same time.
Based on the above knowledge, the present invention was made.

It also will cause children and infants disliking hair washing to do it without hating.
A first invention is a method for producing a solution for making a lather.
A second invention is a solution for making a lather.
The solution is specially a solution for making a lather of which color can be clearly recognized with the naked eye. For example, when a shading of color is shown by gradation of 10 stages, the shading of color of the lather made by the solution is at a level deeper than the 7th stage (numerical value: 3) from the deeper color of the gradation. Preferably, the solution is at a level deeper than the 6th stage (numerical value: 4) from the deeper color of the gradation. More preferably, the solution is at a level deeper than the 5th stage (numerical value: 5) from the deeper color of the gradation. Further preferably, the solution is at a level deeper than the 4th stage (numerical value: 6) from the deeper color of the gradation. Setting upper limit is meaningless. The upper limit may be set to, for example, the 4th stage from the deeper color of the gradation.
Here, the gradation of the shading of color is shown as follows: a case where a content of the coloring material is 0 (only pure water) is 0th stage; and a case where the coloring material-saturated aqueous solution (water is pure water) (i.e., a case where a concentration of the coloring material is the most dense) is set to 9th stage. In this manner, the shading of color is shown here by the gradation of 10 stages. That means, a larger value shows a deeper color.
The solution is, for example, a non-aerosol type solution which uses no compressed gas for making a lather. The solution is, for example, a solution which is put in a container body of a device having the container body, an outlet, and a pump, wherein the pump action causes the solution and the air in the container body to mix each other to eject a colored lather through the outlet.
The solution contains at least a frothing agent, a coloring material, and water. There exist chemically unreacted frothing agent and coloring material between the frothing agent and the dye in the solution. For example, regarding the dye contained in the solution, the reaction with the water lowers a reaction with the frothing agent to thereby allow existence of unreacted coloring material in the solution.

Therefore, the use of glycerin is suitable for the application of the present invention.

The solution according to the present invention is produced in a manner as follows.
Initially, the coloring material (colorant, coloring agent e.g., dye or pigment) was mixed with (added to) water (e.g., distilled water or purified water). The ratio was as described above. The mixture was subjected to stirring. This made the coloring material (colorant, coloring agent e.g., dye or pigment) well dissolved.
A coloring material-containing aqueous solution in which the coloring material was dissolved was mixed with (added to) the frothing agent (foaming agent, e.g. surfactant). It was subjected to stirring. This made the frothing agent well dispersed.
The pH adjuster, the glycerin, etc., were also mixed with (added to) the dye-containing aqueous solution, as required, together with (or one by one with) the surfactant.
