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, more specifically to cleaning power on hard surfaces, particularly scum stains and sebum stains in bathrooms, etc., and inorganic stains in toilet bowls and even kitchen areas. The present invention relates to a detergent composition for hard surfaces, which has excellent detergency against various kinds of hard surface stains such as oil / inorganic composite stains, has a reduced amount of wiping residue after washing, and has excellent long-term storage stability.

[0002]

2. Description of the Related Art Conventional detergent compositions are used properly depending on the type and degree of stains. That is, surfactants and solvent systems are used for hand stains and unmodified oil stains that are relatively lightly soiled, and oil and grease stains that have been altered by the action of heat, sunlight, oxygen in the air, etc. around the kitchen. Is a detergent, a solvent, an alkaline cleaner, and a detergent, a solvent, and a sequestering agent for metal soap in the bathroom, especially calcium salts of fatty acids, and dirt in the toilet bowl. Cleaning agents are becoming mainstream. In fact, it is extremely rare for each stain to exist as a single component, and as a result of our research, it has become clear that divalent metal ions act as a binder for stains regardless of whether they are organic or inorganic stains. There is. As a result, it is extremely important to apply a sequestering agent, which acts synergistically to stains with a cleaning substrate such as an activator or a solvent, to a hard surface cleaning agent. Generally, the sequestering agent, which is the main component of the detergent, is a phosphorus compound represented by tripolyphosphate, a hydroxycarboxylate represented by citrate, from the viewpoints of detergency, cost and the like.
Chelating agents represented by ethylenediaminetetraacetate and diethylenetriaminepentaacetate have been used. However, sodium tripolyphosphate is excellent in chelating ability, but since it has phosphorus, it has contributed to the eutrophication phenomenon of rivers and lakes. Therefore, it is rarely used at present. On the other hand, a hydroxycarboxylic acid salt represented by citric acid has a relatively weak chelating ability and is rarely used alone as a hard surface cleaning agent. On the other hand, chelating agents represented by ethylenediaminetetraacetate also have very high chelating performance, but do not necessarily act synergistically with other cleaning components (for example, solvents, surfactants, etc.), At present, it cannot be said that the compound is a satisfactory compound in view of the problem that the compounded fabric is colored under a long-term storage condition and the biodegradability by microorganisms in the natural environment. In addition, as a stain on the bathroom and the like, there is a lot of stains on the human body and stains around the kitchen mainly due to oils and fats, and it is a complex stain using metal ions as a binder. It is also desired to improve the cleaning power for these stains.

[0003]

SUMMARY OF THE INVENTION Accordingly, the object of the present invention is to prevent hard surfaces, especially scum stains in bathrooms, sebum stains, inorganic stains in toilet bowls, etc., as well as oil / inorganic composite stains around the kitchen. The object is to provide a hard surface cleaner composition which has excellent cleaning power and has a small amount of wiping residue after cleaning and excellent long-term storage stability.

[0004]

[Means for Solving the Problems] As a result of intensive studies conducted by the present inventors in such an actual situation, a specific aspartic acid-N, N-diacetic acid or a salt thereof and a surfactant mixed in a specific ratio were used. By adding a water-soluble solvent, it has been found that a cleaning agent having excellent cleaning power against stains on various hard surfaces, having reduced uncleaned residue, and having excellent long-term storage stability can be obtained, and the present invention is completed. Came to.

That is, the present invention comprises (A) aspartic acid-N, N-diacetic acid represented by the following general formula (I) or a salt thereof:
30% by weight, (B) 0.1 to 30% by weight of a surfactant, and (C) 0.1 to 50% by weight of a water-soluble solvent.
(C) Component content ratio (B) / (C) is 5/1 by weight ratio
It is intended to provide a hard surface cleaner composition which is 1/50.

BEST MODE FOR CARRYING OUT THE INVENTION The detergent composition of the present invention will be described in detail below. The general formula of the component (A) of the present invention
Aspartic acid-N, N-diacetic acid or its salt represented by (I) is capable of binding divalent metal ions such as calcium as a binder in various stains (organic substances (fatty acid calcium, etc.), inorganic substances) on the hard surface. It is used as a decomposition component of stains by chelating and shows higher cleaning performance than hydroxycarboxylic acid salts such as citric acid which is generally used as a chelating agent, and coloring property due to long-term storage compared to ethylenediamine tetraacetate (EDTA). Is extremely small, and the finishability after cleaning (there are few traces of unwiping) is good. Further, unlike EDTA, it has biodegradability, which is advantageous from the environmental aspect.

The surfactant which is the component (B) of the present invention is (A)
Acts synergistically as a detergency enhancer for the ingredients. Examples of surfactants include cationic surfactants, amphoteric surfactants, nonionic surfactants, and anionic surfactants.The surfactants that act synergistically as the detergency enhancer of the component (A) are cationic surfactants. Activators and amphoteric surfactants are preferable, and cationic surfactants are particularly preferable. It is extremely rare for each stain on the hard surface of a house to exist as a single component, and as mentioned above, divalent metal ions act as a binder for stains regardless of whether they are organic or inorganic stains. It is very important to apply the agent to hard surface cleaners, and it is very important to use a surfactant that acts synergistically on the soil with the sequestering agent. Although the detailed mechanism of washing is unknown, cationic surfactants and amphoteric surfactants are preferable,
Among them, cationic surfactants are effective when compared to ordinary hydroxycarboxylic acid salts such as citric acid and ethylenediaminetetraacetate (EDTA), more effectively like a complex with component (A). It is easy to form so that the divalent metal ion is easy to act on the dirt that is the binder, or the activator itself acts on the dirt (A)
It is considered that it is susceptible to decomposition by the components.

Examples of the component (B) used in the present invention include the following.

<Cationic Surfactant> The cationic surfactant is not particularly limited, but a quaternary ammonium salt is preferable, and among them, the following general formulas (1), (2) and
