Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a solid surface cleaning agent, and more particularly to a liquid cleaning composition exhibiting excellent cleaning properties against stubborn stains and having a low foaming property.

[Problems to be Solved by Prior Art and Invention]

In general, dirt on a solid surface has a longer time from contamination to cleaning than dirt on clothes or the like, and therefore adheres strongly to a substrate surface, which makes cleaning difficult. Therefore, in order to remove such dirt, it is necessary to use a strong alkali agent or a specific solvent, or to apply a strong mechanical force to improve the cleaning property. However, the use of a strong alkali agent may damage the surface of a solid substrate, especially the surface of paint that has been aged, and in the case of mechanical force, the cleaning surface differs depending on the object, so a cleaning agent suitable for it may be used. I have to prepare
This is extremely difficult, and at best in a general household,
There was no choice but to rely on human power with a sponge, scrubbing brush, etc., and a great deal of labor was required for cleaning.

[Means for solving problems]

Under such circumstances, as a result of intensive studies by the present inventors, a detergent composition capable of desorbing stains on a solid surface within a neutral to weakly alkaline range that does not affect the substrate on the solid surface. Then, the present invention has been completed.

That is, the present invention provides the following formula (I): (Wherein R represents an alkyl group having 1 to 3 carbon atoms) and (B) an alkylbenzene sulfonate or benzoate having an alkyl group having 1 to 4 carbon atoms. A characteristic liquid detergent composition is provided.

The compounding amount of the 1.3-dialkyl-2-imidazolidinone represented by the formula (I) of the component (A) of the present invention is usually 1 to 20.
%, Preferably 5 to 20% by weight.

Examples of the alkylbenzene sulfonic acid as the component (B) include paratoluene sulfonic acid, orthotoluene sulfonic acid, xylene sulfonic acid, cumene sulfonic acid and butyl sulfonic acid. Among them, paratoluene sulfonic acid is particularly preferable. Examples of the salt of alkylbenzenesulfonic acid or benzoic acid include sodium, potassium, ammonium, monoethanolamine, diethanolamine, triethanolamine and the like. The blending amount of these (B) components is usually 0.5 to 10% by weight, preferably 1 to 5% by weight.

The liquid detergent composition thus obtained causes the dirt to float from the surface of the substrate, particularly when the undiluted solution is applied or left on the dirty portion of the solid surface, and thus the surface of the substrate is damaged when wiped off. You can easily remove stains without. Further features of this detergent composition are:
This means that if it is wiped off as it is, it is extremely easy to wipe it off, and if the surface to be washed is washed with water and then dropped off, it is easy to rinse.

Furthermore, the liquid detergent composition of the present invention can be used by diluting it with a large amount of water in the case of removing large-scale soil such as a floor or soil that is not stubborn. In this case, it is preferable to further add (C) a nonionic surfactant. As the nonionic surfactant, for example, C8 ~ C2
Ethylene oxide adduct of alcohol having 2 straight or branched chain (addition mol number: 1 to 100 mol, preferably 6 to 20 mol), ethylene oxide addition of alkylphenol having C 8 to C22 straight or branched chain (Additional mol number: 1 to 100 mol, preferably 6 to 20 mol), and the like. The blending amount of the component (C) is 0.1 to 20% by weight, especially 0.5.
~ 10 wt% is preferred.

The liquid detergent composition of the present invention further includes, if necessary, an anionic surfactant, a surfactant such as an amphoteric surfactant,
Urea, pyrophosphate, tripolyphosphate, orthophosphate, sulfate, nitrate, chloride, fragrance, pigment, dye and the like can be added.

〔Example〕

 Next, examples will be described.

Example 1 A composition shown in Table 1 was prepared using 1,3-dimethyl-2-imidazolidinone and sodium paratoluenesulfonate.
