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 disinfecting effect and has a good finish with no remaining wipe.

[0002]

2. Description of the Related Art
The following three types of hard surface cleaning compositions are used depending on the type and degree of dirt. That is, a surfactant / solvent-based cleaning agent is applied to a light stain or a non-denatured oil stain having a relatively low degree of soiling, due to the action of heat around the kitchen, sunlight, oxygen in the air, etc. Surfactants / solvents / alkali detergents are used for stains, and detergents / solvents / sequestrants are mainly used for metal soaps in bathrooms, especially for calcium salts of fatty acids. It 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, traces of wiping remain even after the cleaning, resulting in an insufficient finish, requiring wiping twice or rinsing sufficiently with water, which is complicated.

As an attempt to solve such a problem, Japanese Patent Application Laid-Open No. 29498/1990 discloses a liquid for residential use containing an anionic surfactant, a terpene-based hydrocarbon solvent and a water-soluble divalent metal salt as essential components. A cleaning composition is disclosed. However, when cleaning glass surfaces etc. with this one, although the finish is considerably improved, the cleaning power,
For practical use in terms of foaming power and the like, further improvement was necessary. In addition, Japanese Patent Publication No. Sho 62-501570 discloses that
Although a cleaning composition for hard surfaces comprising a glycoside surfactant, a solvent, a water-soluble cleaning agent and a builder is disclosed, this also required sufficient rinsing since residual wiping was observed.

On the other hand, quaternary ammonium salt type cationic surfactants are usually used as a disinfectant. For example, JP-A-3-182597 discloses a liquid detergent composition for floors in which a monolong-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 a higher detergency, and thus it has been possible to obtain sufficient detergency and sterilization effect. Could not.

[0006] Accordingly, there has been a demand for a detergent composition which is excellent in detergency and disinfecting effect and has a good finish without wiping residue upon wiping.

[0007]

Under these circumstances, the present inventors have conducted intensive studies and as a result, have found that a diphenyl ether disulfonic acid type anionic surfactant and a quaternary ammonium salt type cationic surfactant have a specific ratio. The present inventors have found that the composition contained in (1) is excellent in detergency and disinfecting effect, and has a good finish without wiping residue, thereby completing the present invention.

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

A linear or branched alkyl or alkenyl group having from 15 to 15 carbon atoms, but an alkyl group having 8 to 14 carbon atoms, particularly 12 to 14 carbon atoms, is preferred from the viewpoints of detergency and little wiping residue during wiping. M and M 'are a hydrogen atom, an alkali metal such as sodium or potassium, an ammonium group, or an alkanol-substituted ammonium group such as monoethanolammonium or diethanolammonium, with an alkali metal being preferred. The preferred compounding ratio of the two compounds (1) and (2) of the component (A) is (1) by weight.
/ (2) = 100/0 to 25/75, more preferably 95/5 to 70/30. This ratio is 25/7
Less than 5, ie, less than the compound of (1), is not preferred because the wiping properties during wiping may be insufficient. The above compounds (1) and (2) are obtained by a usual method of alkylating by a Friedel-Crafts reaction of diphenyl ether, then sulfonating with sulfur trioxide or the like in an inert solvent such as dichloromethane, and then neutralizing. Can be The alkylation reaction for diphenyl ether occurs selectively at the para-position, but depending on the reaction conditions such as the amount of the alkylating reagent to be used, there may be obtained one having a different number of alkylations and a different orientation. However, there is no particular problem as long as the compounds represented by (1) and (2) are included as the main components.
