Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a liquid detergent composition.

[0002]

2. Description of the Related Art A cleaning agent has a high detergency to remove strong dirt attached to an object to be cleaned, and a single impregnation operation when cleaning through an absorbent carrier. There is a demand for the continuity of the cleaning work time that can be carried out at a time. Examples of the method of washing through an absorbent carrier include a dishwashing agent for hand washing, a body washing agent, and a hard surface washing agent. In particular, for washing dishes and cooking utensils, a method of rubbing with a flexible absorbent such as a sponge or a towel while contacting the dishes with a water diluent of a detergent has been known. In India, a method is commonly used in which a cleaning solution and a small amount of water are directly soaked into a flexible absorbent body to rub and wash dishes and the like. Agents are needed.

[0003] Japanese Patent Publication No. Hei 11-503377 discloses a method in which a surfactant composition which can be densified with a small amount of water is contained in an adsorbent such as a sponge, and then the surfactant impregnated with the surfactant composition is admixed with water. A washing method has been disclosed in which the surfactant composition is concentrated in an adsorption carrier by treating the surfactant to prolong the outflow of the surfactant. However, this technique is not satisfactory in the cleaning effect itself. As a method of improving the washing effect, it is conceivable to increase the concentration of the surfactant. However, if this technique is applied to the above-described technique, a problem occurs in that the composition is gelled. Not at all.

Japanese Unexamined Patent Publication No. 11-513067 discloses a technique relating to a dishwashing detergent in which a washing solution having a high surfactant concentration is dissolved in water without gelling. This technique is to prevent the detergent from gelling at a high surfactant concentration by blending a gelling inhibitor. However, the composition disclosed in this publication cannot wash many dishes when the flexible absorbent is impregnated with a small amount of water and a washing liquid and washed.

On the other hand, an organic solvent containing a hydrotrope or a lower alcohol is used as a liquid detergent for the purpose of improving storage stability or as a viscosity modifier. JP-A-6
Japanese Patent No. 505032 discloses a liquid detergent containing a specific surfactant, a monohydric alcohol and a hydrotrope. JP-A-11-273500 describes that ethanol is useful for improving low-temperature stability. JP-A-6-33099 describes that an organic solvent containing a lower alcohol or a hydrotropic agent can be used as a viscosity reducing agent. However,
According to the compositions described in these publications, the washing solution and a small amount of water are directly impregnated into the flexible absorber for washing, so that the washing power cannot be maintained.

An object of the present invention is to provide a method for washing a flexible absorbent article by impregnating it with a small amount of water and a washing solution without impairing the storage stability, especially at low temperatures where conditions are severe. It is an object of the present invention to provide a liquid detergent composition exhibiting a cleaning effect and a sustained cleaning effect.
