DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hard surface cleaning composition which has a small amount of unwiped residue and an excellent effect of preventing contamination.

[0002]

2. Description of the Related Art Conventional cleaning compositions are properly used depending on the type and degree of stains. That is, a surfactant / solvent-based cleaning agent is deteriorated due to the action of heat around the kitchen, sunlight, oxygen in the air, and the like for relatively small stains, undenatured, and oily stains. A surfactant / solvent / alkali agent-based cleaning agent is used for grease stains and the like, and a surfactant / solvent / sequestering agent-based cleaning agent is used for metal soaps in the bathroom, especially for calcium salts of fatty acids. It is becoming mainstream. When these cleaning agents are used, since the surfactant and the alkali agent remain on the surface to be cleaned, wiping marks remain even after the cleaning, and it is necessary to wipe twice or rinse thoroughly with water.

To solve these problems, Japanese Patent Laid-Open No.
Japanese Patent No. 29498 proposes a liquid cleaning composition for dwelling which does not require rinsing, and Japanese Patent Publication No. 62-501570 discloses a liquid cleaning composition comprising an alkylglycoside / solvent / builder as having good rinsing properties. However, the former has insufficient finish when cleaning the glass surface, etc., and the latter uses an inorganic powder builder, so residual wiping is observed and sufficient rinsing is required. Met.
