Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a liquid detergent composition. For more details, it has excellent cleaning properties against oil and grease stains on furniture, floors, glass products, etc., excellent workability such as adhesion to wall surfaces and wiping properties due to foaming properties, and finish properties with few remaining traces of wiping The present invention relates to a liquid cleaning composition excellent in the above.

[0002]

2. Description of the Related Art Conventionally, the following liquid detergent compositions for hard surfaces such as furniture, floors, around kitchens, glassware, etc. are properly used depending on the type and degree of dirt. Surfactants and solvent-based detergent compositions are used for hand stains and undenatured oils, which have a relatively low degree of dirt, and act as heat from around the kitchen, sunlight, and oxygen in the air. A detergent composition of a surfactant, a solvent, and an alkali agent is mainly used for oil and fat stains and the like that have been altered by the above method. However, when these cleaning compositions are used, surfactants and alkalis remain on the surface to be cleaned, and especially on window glasses, etc., wiping marks remain even after cleaning, resulting in insufficient finish. It had to be wiped or rinsed thoroughly with water.

As an attempt to solve such a problem, Japanese Patent Application Laid-Open No. 4-85400 discloses a high detergency and low trace of wiping comprising a specific anionic surfactant and a specific amphoteric surfactant. Liquid detergent compositions have been proposed. However, this detergent composition was not good in workability, for example, liquid dripping occurred on a vertical surface, bubbles were excessively formed at the time of wiping, and time was required for finishing.

[0004] Further, in Japanese Patent Application Laid-Open No. Hei 6-228593, a cleaning composition for hard surfaces comprising a diphenyl ether disulfonic acid type anionic surfactant has a high detergency and has little trace of wiping. It has been proposed as. However, this detergent composition is not satisfactory because it has insufficient detergency against grease stains.

[0005]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a good detergency for oil and dirt, excellent workability such as good adherence to a wall surface and wiping properties by a proper foaming property. Another object of the present invention is to provide a liquid detergent composition which has a good finish with little remaining traces after wiping.
