These surfactants may be used alone or in combination of two or more, in an amount of 5 to 30 with respect to the total amount of the foaming detergent.
It is blended in a ratio of weight%. When the amount is less than 5% by weight, the agent does not function as a cleaning agent.
If the content exceeds% by weight, the viscosity becomes high, and it is difficult to generate and discharge bubbles.

In the present invention, among these surfactants, it is preferable to blend a higher fatty acid salt at a ratio of 5 to 15% by weight, since finer foam quality can be obtained.

These betaines are zwitterionic surfactants and have a function of improving the retention of foam after ejection. Such betaine is preferably used alone or in combination within the range of 1 to 5% by weight based on the total amount of the detergent.

[0009] The foamable detergent of the present invention is obtained by the Rossmiles method.
(25 ° C., 1%), it preferably has a foaming property of 200 cm ³ or more,
It is preferable that the viscosity is not more than cps, and the amount of the surfactant used is adjusted within the above-mentioned range of the compounding amount so that the foaming properties and the viscosity are obtained. If the foaming property is weak, the composition does not function sufficiently as a cleaning agent, and if the viscosity is high, mixing with air is difficult, or it is difficult to pass through a foam generating means of a container, for example, a porous body.

The foaming detergent of the present invention contains a monohydric alcohol and a polyhydric alcohol as a viscosity modifier. Examples of the monohydric alcohol include methyl alcohol, ethyl alcohol, propyl alcohol, and isopropyl alcohol, and ethyl alcohol is particularly preferable. Polyhydric alcohols include propylene glycol,
1,3-butylene glycol, glycerin, sorbitol, maltitol, xylitol, glucose, polyethylene glycol 400, polyethylene glycol 60

These alcohols are added in accordance with the concentration of the surfactant, but the monohydric alcohol is blended in the range of 1 to 7% by weight, and the polyhydric alcohol is added in an amount of 3 to 7% by weight based on the total amount of the detergent.
It is blended within a range of ２０20% by weight. When the amount of the alcohol added falls below the above range, the viscosity of the detergent increases, and foaming is inhibited. Conversely, when the amount of the alcohol added exceeds the above range, the viscosity of the detergent decreases, and the foaming property also decreases.

If necessary, the foaming detergent of the present invention may contain other additives usually used in this type of detergent, for example, antioxidants, preservatives / bactericides, ultraviolet absorbers, humectants. , A thickener, a dye, a fragrance and the like are appropriately blended.

EXAMPLES Examples of the present invention and comparative examples will be described below. Examples 1 to 22 and Comparative Examples 1 to 18 The foaming detergents of Examples 1 to 22 were prepared by stirring and mixing the components shown in Tables 1 and 2 according to a conventional method. On the other hand, the detergents of Comparative Examples 1 to 18 were prepared by similarly stirring and mixing the components shown in Tables 3 and 4. The viscosity (25 ° C., cp
s), foam quality, and foam retention. The results are shown in Tables 1 to 4.

Test Method 1. Evaluation of foam quality Using a porous body having a fixed pore diameter, a predetermined ratio of a detergent and air were mixed, and the state of the foam when the foam was discharged was visually evaluated in three stages. ：: Fine texture. Δ: Somewhat fine. ×: coarse texture and settling. 2. Evaluation of Retention of Foam Using a porous body having a fixed pore diameter, a predetermined ratio of a cleaning agent and air are mixed, and the foam is discharged. Assuming that the height of the top of the bubble after minutes is h, the retention of the bubble is defined by the following equation. Foam retention (%) = h / H × 100 The foam retention was evaluated using the retention as follows. A: The retention is 80% or more, and the retention of foam is excellent. ：: The retention is 60% or more and less than 80%, and the retention of foam is good. Δ: The retention is greater than 40% and less than 60%, and the retention of foam is normal. X: The retention is 40% or less, and the retention of foam is poor. 3. Measurement of Viscosity of Detergent The viscosity was measured at 25 ° C. using a BL type viscometer (manufactured by Tokyo Keiki).

[Table 4]

As is clear from Tables 1 and 2, all of the foaming detergents of Examples 1 to 22 had a viscosity at 25 ° C. of not more than 100 cps, had a fine foam quality, and were discharged. A foam with excellent later retention was produced.
In particular, in Examples 18 to 22 to which coconut oil alkyl betaine and / or coconut oil fatty acid amidopropyl betaine were added as surfactant components, the retention of the generated foam was extremely excellent. Further, from Examples 1 and 11 to 13, it does not depend on the pore diameter of the porous body in the foam ejection pump container, and from Examples 1 and 14 to 15, it depends on the mixing ratio of air and the cleaning agent in the foam ejection pump container. It can be seen that a good quality foam can be obtained without any.

On the other hand, as is clear from Tables 3 and 4, in Comparative Examples 1, 7 and 13 in which the amount of the surfactant added was small, the viscosity of the detergent was too low, so that the texture was coarse and the retention was poor. Only inferior foam was obtained. Conversely, in Comparative Examples 2, 8, and 14 in which the amount of the surfactant added was large, the viscosity of the detergent was too high, so that it was difficult to generate bubbles and discharge bubbles. In Comparative Examples 3, 9 and 15 in which the amount of the monohydric alcohol added was small, the viscosity was still high, and it was difficult to generate and discharge bubbles. Conversely, in Comparative Examples 4, 10 and 16 in which the amount of the monohydric alcohol added was large, the retention of foam was impaired, and good-quality foam was not obtained. Comparative Examples 5, 11 and 17 in which the amount of polyhydric alcohol added was small.
In this case, the viscosity was still high, and it was difficult to generate and discharge bubbles. Conversely, in Comparative Examples 6, 12 and 18 in which the amount of the polyhydric alcohol added was large, although the viscosity of the detergent was moderate, only foams with coarse texture and poor retention were obtained.

From the above, since the foaming detergent of the present invention contains a specific compounding component in a specific ratio, when used in a foam ejection pump container, it has a fine foam quality and has a fine A foam having excellent holding properties can be produced.

[0023]

According to the present invention, when used in a bubble jet pump container which discharges as a foam by being mixed with air and passing through a porous material, it has a fine-grained foam having optimum characteristics for cleaning. At the same time, a foaming detergent that produces foam having excellent retention after discharge can be obtained.
