When the content of the anionic surfactant is less than 0.1% by weight, the action of dispersing and solubilizing dirt is weak, and the interaction with the components (B) and (C) is not sufficient. On the other hand, if the blending amount is more than 20% by weight, no special improvement effect is brought to the detergency and conversely the foam breakage / rinseability deteriorates, which is not preferable.

When the amount is less than 1, the detergency and foaming performance are poor, and the component (A)
Also the interaction with (C) is not sufficient. On the other hand, 50
If the amount is more than wt%, no significant compounding effect is observed and it is uneconomical. The component (C) may be used alone or in combination of two or more.

PH of the residential liquid cleaning composition of the present invention
Is in the range of 5-11, preferably 6-9. When the pH of the composition is less than 5 and more than 11, detergency,
Foam performance is poor, and it may adversely affect the object to be washed.

The liquid detergent composition for residential use of the present invention is obtained by incorporating the above-mentioned components (A), (B) and (C) as essential components and adjusting the pH of the composition to 5-11. However, these synergistic effects are inhibited by the amine component present in the composition. Therefore, in the present invention, a more stable effect can be expected by adjusting the amount of the amine component in the composition to 1000 ppm or less.

Further, in the present invention, other optional components may be appropriately blended if necessary. As these optional components, in order to improve detergency and foaming performance, a nonionic surfactant or the like can be blended as a surfactant other than the components (A) and (B).

Dyes, antioxidants, thickeners, ultraviolet absorbers and the like can be optionally added. Incidentally, these optional components are usually
Any cleaning agent may be used as long as it is used as a cleaning agent, and is not particularly limited.
