DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning agent used for cleaning hard surfaces, and more particularly to a hard surface cleaning agent containing a specific alkylpropylnaphthalene.

[0002]

2. Description of the Related Art Dirt on hard surfaces such as ventilation fans, ovens, bathtubs, tiles, toilet bowls, glass, metal, etc. is obtained by fixing oils and fats and various organic substances to resin by heat or air, or the like, or , A resin or a coating of ink or the like. Detergents such as kitchen detergents have weak cleaning power against the above dirt,
It was difficult to remove dirt firmly fixed on the hard surface using this. Therefore, in order to remove such dirt on the hard surface, a method of adding an acid or an alkaline substance to a cleaning agent to increase the detergency by strong alkalinity or acidity, an ethylene glycol ether solvent, acetone, or A method of adding a solvent such as a chlorine-based solvent has been used.

[0003] Among the conventional methods, the method of adding sodium hydroxide or hydrochloric acid to make the detergency strong alkaline or strongly acidic requires the use of rubber gloves for cleaning because the detergent irritates the skin. However, there is a disadvantage that rubber gloves are corroded depending on the type of hard surface cleaner. Further, ethylene glycol ether-based solvents, acetone, xylene, or a cleaning agent to which a chlorine-based solvent is added, although showing a considerable detergency, some of the solvents are highly toxic to the human body, which is preferable in use. I can not say. In particular, those containing an ethylene glycol ether-based water-soluble solvent have a strong irritating odor, so the odor is bothersome during use of the cleaning agent, and the desired scent can be obtained even if the fragrance is further applied. There is a disadvantage that there is no.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to provide a hard surface cleaner having a strong detergency, a low odor, a low toxicity and a low irritation.

[0005]

The above problems can be solved by using an alkylpropylnaphthalene compound having a specific chemical structure according to the present invention. That is, the hard surface cleaner of the present invention has the following formula (I):

Embedded image (Where k and n represent 0 or an integer of 1-2, but k and n are not both 0, the sum of k and n is 1 or 2, and m is 1 or 2 Wherein at least one alkylpropylnaphthalene compound represented by the formula (1) is contained at a content of 0.1 to 60% by weight.

[0006]

The alkylpropylnaphthalene compound of the formula (I) used in the hard surface cleaner of the present invention is selected from dimethylmonopropylnaphthalene, dimethyldipropylnaphthalene, monomethylmonopropylnaphthalene, and monomethyldipropylnaphthalene. preferable.

Since the alkylpropylnaphthalene compound used in the present invention is insoluble in water, it is preferable to use an emulsifying system for a hard surface cleaner using water as a medium. The emulsifier that can be used in this case is not particularly limited, but it is preferable to use a general nonionic surfactant.

The alkyl propyl naphthalene compound of the formula (I) is soluble in organic solvents such as acetone, methyl ethyl ketone, tetrahydrofuran, methylene chloride, kerosene, and turpentine oil. A hard surface cleaner is obtained.

The amount of the alkylpropylnaphthalene used in the present invention in the hard surface cleaner is 0.1 to 60%, preferably 0.5 to 40%, based on the total weight of the cleaner.
%. If the content is less than 0.1 (weight)%, the cleaning power of the obtained cleaning agent is insufficient, and even if it is contained more than 60%, the cleaning power is saturated, which is economically disadvantageous.
