Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning composition for hard surfaces, and more particularly to a cleaning composition having excellent cleaning performance against oily stains such as kitchens and window glasses, and having good finish after cleaning. And a cleaning composition for hard surfaces.

[0002]

2. Description of the Related Art Dirt on hard surfaces such as glass products and products partially using glass, plastic products, steel products, furniture, appliances, desks, chairs, floors, windows, etc. is contaminated. If the time from cleaning to cleaning is prolonged, the cleaning becomes difficult because the adhesion of dirt to the substrate surface becomes strong. For example, a dirt substance attached to a ventilation fan, a wall around a kitchen, a glass, a refrigerator, or the like is oxidized when left for a long time and changes to a sticky modified oil.
Also, besides the kitchen area, the entire house,
There are oily stains, such as stains, which are difficult to wash.

As a cleaning agent for removing such oily stains, a surfactant / solvent / alkali agent-based cleaning agent has become mainstream. Among these cleaning agents, there have been known, as an alkali agent, a cleaning agent mainly composed of an inorganic strong alkali such as sodium carbonate and sodium hydroxide, or an organic amine or a water-soluble organic solvent.

When these cleaning agents are used as a stock solution, there is a problem in safety with respect to inorganic alkali agents, and since they are non-volatile, they remain as wiping marks on the surface to be cleaned, giving an undesirable result in appearance. Was something. Also, when a volatile or liquid organic amine is used in place of the inorganic alkaline agent, the surfactant remains on the surface to be cleaned as a wiping mark, and it has been necessary to sufficiently rinse with water after using the undiluted solution.

In order to solve these problems, Japanese Patent Laid-Open Publication No. Hei.
No. 29498 proposes a liquid cleaning composition for dwelling which does not require rinsing, and Japanese Patent Publication No. 62-501570 proposes a liquid cleaning composition comprising an alkyl glycoside / solvent / builder as having good rinsing properties. However, in the former, the finish is still insufficient when the glass surface is washed, and in the latter, when a commercially available sprayer is used, foaming is poor, and liquid dripping occurs on a vertical surface such as a window glass, In the latter case, since the builder of the inorganic powder is used, a residue after wiping was observed, and sufficient rinsing was required.

As described above, a cleaning composition for hard surfaces which has a strong detergency and has little residue after cleaning and has solved the problem of foaming power has not yet been obtained. Therefore, an object of the present invention is to improve the cleaning performance, particularly the cleaning performance against oily stains such as kitchens and window glasses, and achieve a good finish.
In other words, it is an object of the present invention to provide a hard surface cleaning composition which hardly remains after cleaning, does not need to be sprayed twice, and has no stickiness.

[0007]
