The following analysis is given in light of this disclosure.

BACKGROUND ART Pump formers that discharge cleaning agents such as body soap and hand soap in the form of foam have become popular. For example, cleaning agents for pump formers used to apply cosmetics to the skin are required to be able to form foam of good quality that is difficult to defoam even during cleaning. Therefore, in order to discharge foam of good quality from such a pump former, the cleaning agent needs to have a low viscosity. Therefore, if the viscosity of the cleaning agent is lowered by increasing the content of the oily component, the oily component will reduce the sustainability of the foam, making it impossible to discharge foam with good quality. On the other hand, if an attempt is made to increase the persistence of foam by increasing the content of the surfactant, the viscosity will increase, making it impossible to discharge foam of good quality from the pump former. That is, there is a trade-off relationship between low viscosity and foam persistence. Therefore, there is a need for a cleaning agent that has a low viscosity and has a long-lasting foam.

Regarding the aqueous liquid cleansing composition described in Patent Document 1 and the skin cleansing agent described in Patent Document 2, the quality of the foam, such as the persistence of the foam discharged from the pump former, has not been studied.

(In the chemical formula shown in Chemical Formula 1, any one of R ¹ , R ² and R ³ is an alkyl group, alkenyl group or acyl group having 4 to 15 carbon atoms, and the other two are hydrogen groups. .)

A method for manufacturing the cleaning composition of the present disclosure will be described. The cleaning composition of the present disclosure can be produced by a generally known method without any particular method. For example, a cleaning composition can be prepared by mixing the above components.

When adding components (H) and (I), it is preferable that the fatty acid taurine salt, which is a complex of components (H) and (I), is generated in advance and then added to the composition. For example, a fatty acid taurine salt can be prepared by dissolving component (H) in water under heating and adding component (I) to an aqueous solution of component (H). By adding the fatty acid taurine salt prepared in advance in this way, the cleaning composition of the present disclosure can be manufactured.

In some cases, the behavior of each component in a cleaning composition is unclear. For example, component (H) and component (I) are thought to form a fatty acid taurine salt, but it is necessary to directly identify the structure or behavior of component (H) and component (I). It is difficult or highly impractical to do so. Therefore, if the cleaning composition of the present disclosure cannot be directly identified by its composition, it should be allowed to be described by its manufacturing method.

The cleaning composition of the present disclosure will be explained below by giving examples. However, the cleaning composition of the present disclosure is not limited to the following examples. Further, in the following Examples, an example will be described in which the cleaning composition of each test example is applied to cleaning cosmetics, but the composition of the present disclosure is not limited to use in cosmetics. The unit of content of each component shown in each table is mass %.

[Test Examples 1 to 20]
Each composition shown in Table 1 was prepared and discharged from a pump former, and the discharged foam was evaluated based on the following criteria. The pump former used is a commonly used type in which the nozzle is manually pushed into the container from top to bottom to force the foam to be discharged from the nozzle. The viscosity of each composition was measured at 30° C. using a Brookfield viscometer (spindle number 1, rotation speed 60 rpm). Tables 1 to 4 show the composition and evaluation of each composition. In Test Examples 1 to 23, the type and content of the alkylene oxide derivative (D) were varied. In the table below, components for comparing the effects of adding alkylene oxide derivatives are classified as component (D) even if they fall under other components. In addition, component (D) is expressed in a manner corresponding to the chemical formulas shown in Chemical Formulas 2 and 4 above, and PO indicates that AO in the chemical formulas shown in Chemical Formulas 2 and 4 above is an oxypropylene group. BO indicates that AO in the chemical formulas shown in Chemical Formulas 2 and 4 above is an oxyalkylene group having 4 carbon atoms.

[Foam quality]
A: The foam had strong elasticity and did not defoam even when touched.
B: The foam had elasticity and was difficult to defoam even when touched.
C: Small bubbles were discharged, and the bubbles had some elasticity.
D: Bubbles were discharged, but there were many large bubbles.
E: Foam was not discharged.

In Test Example 1 in which component (D) was not added, the quality of the foam was low. However, in Test Examples 2 to 12 in which the alkylene oxide derivative shown in Chemical Formula 2 was added, the foam quality could be improved. From this, it was found that the alkylene oxide derivative shown in Chemical Formula 2 above is effective in improving foam quality. Furthermore, the viscosity of the cleaning composition could also be reduced by adding the alkylene oxide derivative. It is thought that the decrease in viscosity also contributed to the improvement in foam quality.

In Test Example 13, in which R ⁴ and R ⁵ in the chemical formula shown in Chemical Formula 2 are cetyl groups (hexadecyl groups), good quality foam was not obtained and the viscosity was high. From this, it is considered that the number of carbon atoms in R ⁴ and R ⁵ is 12 or less, preferably 8 or less, and more preferably 4 or less.

In Test Example 14, in which there was no EO group in the chemical formula shown in Chemical Formula 2, and there was only a PO group (AO group), good quality foam was not obtained and the viscosity was high. Further, in Test Examples 16 and 17 in which there was no EO group and only BO group (AO group), a decrease in viscosity was observed, but no improvement in foam quality was observed. On the other hand, in Test Example 15 in which there were no AO groups and only EO groups, neither a decrease in viscosity nor an improvement in foam quality was observed. From this, it is considered preferable that both the EO group and the AO group exist in the chemical formula shown in Chemical Formula 2.

Comparing Test Examples 2 to 12, good results were obtained for R ⁴ and R ⁵ in the chemical formula shown in Chemical Formula 2 as hydrogen and a hydrocarbon group having 1 to 4 carbon atoms, respectively, but R ⁴ and R ⁵ The best foam could be produced when is a methyl group.

In Test Examples 6 and 21 in which the content of component (F) was 1% by mass to 1.5% by mass, foam with good foam quality could be discharged. From this, it is considered that good foam quality can be obtained when component (F) is at least 0.2% by mass or more, preferably 0.5% by mass or more. In Test Example 22, in which the content of component (F) was increased, a decrease in foam quality was observed.

It is considered that it is even more preferable if it exists.

According to Test Examples 23 and 24 in which the content of component (C) was 1% by mass to 1.5% by mass, foam with good foam quality could be discharged in both cases. From this, it is considered that good foam quality can be obtained when component (C) is at least 0.2% by mass or more, preferably 0.5% by mass or more. In addition, in Test Example 25 in which the amount of component (C) was increased, the viscosity increased and the foam quality decreased. From this, the content of component (C) is preferably 2.8% by mass or less, more preferably 2.4% by mass or less, and 2% by mass or less based on the mass of the composition. It is considered more preferable.

In Test Examples 26 to 29, the contents of components (A) and (B) were varied. In Test Examples 26 and 27 and Test Example 6, there was a tendency for foam quality to improve when the content of components (A) and (B) was increased. From this, it is considered that the content of component (A) is preferably 8% by mass or more, more preferably 8.5% by mass or more, and even more preferably 9% by mass or more. Further, it is considered that the content of component (B) is preferably 4.4% by mass or more, more preferably 4.8% by mass or more, and even more preferably 5% by mass or more. On the other hand, in Test Examples 28 and 29, when the content of components (A) and (B) was further increased, there was a tendency for the foam quality to deteriorate. Furthermore, in Test Example 29, the viscosity increased rapidly. From this, it is considered that the content of component (A) is preferably 10.5% by mass or less, more preferably 10.2% by mass or less, and even more preferably 10% by mass or less. Further, it is considered that the content of component (B) is preferably 7.2% by mass or less, more preferably 6.5% by mass or less, and even more preferably 6% by mass or less.
