Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid detergent composition which is excellent in detergency and sterilizing effect, and has a good finish without wiping residue.

[0002]

2. Description of the Related Art Conventionally, the problems to be solved by the invention
The following three types of hard surface cleaner compositions are used according to the type and degree of dirt. That is to say, for hand stains that are relatively lightly soiled and unmodified oil stains, a surfactant / solvent-based detergent is a fat and oil that has been altered by the effects of heat around the kitchen, sunlight, oxygen in the air, etc. A detergent / solvent / alkaline cleaner is mainly used for stains, and a detergent / metal / sequestrant cleaner is used for metal soaps in the bathroom, especially calcium salts of fatty acids. Is used for.

However, when these cleaning agents are used,
Since the surface-active agent and the alkaline agent remain on the surface to be cleaned, wiping marks remain after cleaning and the finish is insufficient, and it is necessary to wipe twice or rinse thoroughly with water, which is complicated.

As an attempt to solve such a problem, Japanese Unexamined Patent Publication (Kokai) No. 2-29498 discloses a residential liquid containing an anionic surfactant, a terpene hydrocarbon solvent and a water-soluble divalent metal salt as essential components. A detergent composition is disclosed. However, when cleaning the glass surface etc. with this one, although the finish is considerably improved, the cleaning power,
It was necessary to further improve the foaming power and the like for practical use. Further, in Japanese Patent Publication No. 62-501570,
Although a hard surface cleaner composition comprising a glycoside surfactant, a solvent, a water-soluble cleaner and a builder has been disclosed, this also requires sufficient rinsing because wiping residue is observed.

On the other hand, the quaternary ammonium salt type cationic surfactant is usually used as a disinfectant. For example, Japanese Patent Application Laid-Open No. 3-182597 discloses a liquid cleaning composition for floors in which a mono long-chain alkyl type quaternary ammonium salt and a nonionic surfactant are combined. However, it is known that the above-mentioned cationic surfactant forms a complex between compounds when used in combination with an anionic surfactant having more excellent detergency, and thus far sufficient detergency and disinfection effect can be obtained. I couldn't.

[0006] Therefore, there has been a demand for a detergent composition which is excellent in detergency and sterilization effect and has a good finish without being left unwiped.

[0007]

Under such circumstances, the inventors of the present invention have conducted diligent research and, as a result, have found that a diphenyl ether disulfonic acid type anionic surfactant and a quaternary ammonium salt type cationic surfactant are contained in a specific ratio. The present invention has been completed based on the finding that the composition contained in 1) has excellent detergency and sterilization effect, and has a good finish without wiping residue.

That is, the present invention comprises the following components (A) and (B): (A) diphenyl ether disulfonic acid type anionic surfactant (B) quaternary ammonium salt type cationic surfactant, (A) / (B) is a weight ratio of 300/1 to 3 /
