DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid detergent composition, and more particularly to a liquid detergent composition, which does not permeate immediately when taken into a sponge, is retained on the sponge to a certain extent, and has an opaque appearance. The present invention relates to an economical kitchen liquid detergent composition that is easy to visually recognize the squeeze amount and does not overuse.

[0002]

2. Description of the Related Art There are two methods of using a kitchen cleaner: a method in which a thin solution is prepared in a sink or a washing tub, and the dishes are immersed in the dishes and washed, or the dishes are directly attached to a sponge to wash the dishes. Although there is a method, it is often used in the latter cleaning method in general.

Many of the conventional liquid cleaners for kitchens have a transparent appearance, but have a drawback that the squeeze amount is difficult to visually recognize when extruded from a container. On the other hand, there is also a liquid detergent having an opaque appearance, but since the viscosity of the detergent is adjusted to be relatively low in consideration of easy removal from the container, when the liquid is taken directly into the sponge, the liquid is There was a drawback that the squeeze was difficult to visually recognize, because it immediately penetrated into the sponge. As described above, since the amount of the conventional liquid detergent is difficult to visually recognize, the amount of the squeeze is not constant, and the amount of the squeeze used is more than a necessary amount, which is not only uneconomical but also causes rough hands.

[0004]
