Background

Hydrophobic dirt such as sebum and soap scum is easily adhered to a hard surface of a place where water is used, such as a bathroom, and it is one of the dirt that is difficult to clean because hard components in water are floated and firmly adhered. Such strongly adhered dirt is a nutrient component of microorganisms such as mold, and since moderate moisture is always present, mold is easily generated, and the generated mold cannot be cleaned without being removed by a strong oxidizing agent such as hypochlorous acid, which is a large burden. Therefore, it is strongly desired to develop a technique for efficiently removing a nutrient source of microorganisms such as mold and sterilizing the microorganisms by a simple method before the microorganisms such as mold propagate.

< composition et al >

The action mechanism of the mildew-removing detergent composition for hard surfaces according to the first embodiment of the present invention is not clear, but is considered as follows. It is known that molds have thick cell walls on the outer side of cell membranes, and the cell walls of molds include a polysaccharide layer containing glucan-chitin or the like, a melanin layer, a hydrophobin layer, and the like. Consider that: the presence of the cell wall makes the bactericide less permeable to the inside of the cells of the mold than general bacteria such as Escherichia coli, and thus a sufficient mold removing effect cannot be obtained in a short time. Consider that: when an aqueous solution containing the component (a) of the present invention at a specific concentration is allowed to act on a protein such as hydrophobin, a structural change of the protein is caused, and as a result, the amount of the nonionic bactericide as the component (b) of the present invention permeating into the cells of the mold can be increased, and the mold-removing effect can be imparted. However, when this technique is applied to a detergent, the strength of the salt increases by the blending of the component (a), and as a result, when a surfactant that has an effect on the cleaning performance of sebum dirt is blended, there is a problem that the blending stability is lowered. Consider that: in the hard surface mildew-removing detergent composition of the first aspect of the present invention, by further containing the component (c1) and the component (P) in specific amounts as the surfactant in the case where the component (a) and the component (b) are contained, a mildew-removing detergent composition for hard surfaces excellent in mildew-removing performance and sebum-cleaning ability and excellent in formulation stability can be provided.

The mildew-removing detergent composition for hard surfaces according to the first aspect of the present invention contains the component (a) in an amount of 0.1 mass% or more, preferably 0.5 mass% or more, and more preferably 1 mass% or more, from the viewpoint of improving mildew-removing performance, and contains the component (a) in an amount of 5 mass% or less, preferably 4 mass% or less, and more preferably 3 mass% or less, from the viewpoint of formulation stability.

The mildew-removing detergent composition for hard surfaces according to the first aspect of the present invention contains the component (b) in an amount of 0.05% by mass or more, preferably 0.1% by mass or more, more preferably 0.5% by mass or more, and still more preferably 1% by mass or more, from the viewpoint of improving mildew-removing performance, and contains the component (b) in an amount of 7% by mass or less, preferably 5% by mass or less, more preferably 4% by mass or less, and still more preferably 3% by mass or less, from the viewpoint of formulation stability.

The mildew-removing detergent composition for hard surfaces according to the first aspect of the present invention contains the component (c1) in an amount of 0.1 mass% or more, preferably 0.5 mass% or more, and more preferably 1 mass% or more from the viewpoint of formulation stability and cleaning properties, and further contains the component (c1) in an amount of 5 mass% or less, preferably 4 mass% or less, and more preferably 3 mass% or less from the viewpoint of mildew-removing performance.

In the mildew-removing detergent composition for hard surfaces according to the first aspect of the present invention, the content of the component (P) is limited from the viewpoint of formulation stability. In the mildew-removing detergent composition for hard surfaces according to the first embodiment of the present invention, the mass ratio of the content of the component (c1) to the total content of the component (c1) and the component (P), (c1)/[ (c1) + (P) ] is 0.30 or more, preferably 0.40 or more, and more preferably 0.50 or more from the viewpoint of formulation stability, and is 1.0 or less, preferably 0.90 or less, and more preferably 0.80 or less from the viewpoint of cleaning power.

The mildew-removing detergent composition for hard surfaces of the first embodiment of the present invention preferably contains a solvent (but does not include the component (b)) as the component (d) from the viewpoint of improving the mildew-removing effect.

The component (d) is preferably at least 1 solvent selected from the following compounds (d1) to (d 3).

(d1) The method comprises the following steps An aliphatic alcohol having a molecular weight of 60 to 500.

(d2) The method comprises the following steps An aliphatic glycol ether having a molecular weight of 60 to 500.

(d3) The method comprises the following steps An aliphatic diol having a molecular weight of 60 or more and 500 or less.

In the present invention, the logP value is a coefficient representing the affinity of an organic compound for water and 1-octanol. The 1-octanol/water partition coefficient P is a ratio of equilibrium concentrations of compounds in each solvent when a trace amount of the compounds is dissolved as a solute in a solvent of a two-liquid phase of 1-octanol and water to achieve a partition equilibrium, and is generally expressed in the form of log P where the value is 10 with respect to the base. logP values of many compounds have been reported, and many values are disclosed in a database available from the heliochemistry Information Systems (dayright Chemical Information Systems, Inc. (dayright CIS)) and the like, and are therefore referred to. In the absence of a measured logP value, the calculation can be performed by a program CLOGP or the like that can be obtained from the dayright CIS. If there is a measured logP value, the program outputs the measured logP value and a "calculated logP (clogp)", which is calculated by the fragmentation method of Hansch, Leo.

The fragmentation method is a method based on the chemical structure of a compound, which takes into account the number of atoms and the type of chemical bond (cf. a. leo, Comprehensive Medicinal Chemistry, vol.4, c.hansch, p.g. sammen, j.b. taylor and c.a. ramsden, eds., p.295, pegman Press (Pergamon Press), 1990). In selecting compounds, the ClogP value can be used instead of the measured logP value. In the present invention, if there is an actual measured value of logP, the actual measured value of logP is used, and if there is no actual measured value of logP, the CLOGP value calculated by the program CLOGP v4.01 is used.

It is known that molds have thick cell walls on the outer side of cell membranes, and the cell walls of molds include a polysaccharide layer containing glucan-chitin or the like, a melanin layer, a hydrophobin layer, and the like.
