[Solution] A cleaning agent composition for wiping and washing footwear, comprising a nonionic ultraviolet absorber and a surfactant.

Description

Technical Field

[0001] The present invention relates to a cleaning agent composition for wiping and washing footwear that does not require rinsing with water.

Background Art

[0002] Generally, for cleaning sports shoes, sneakers, etc., commercially available laundry detergents or detergents dedicated to sports shoes are used.

[0003] On the other hand, these detergents are basically used in water. After immersing the sneakers in the aqueous detergent solution and scrubbing them with a brush or the like, it is necessary to wash away the detergent components and dirt with water. However, there have been problems such as damage to the fabric due to scrubbing and the time it takes to dry after rinsing with water, making it impossible to wear them immediately.

[0004] Therefore, there has been a certain demand for detergents that can be cleaned without the need to rinse with water. For example, Patent Document 1 describes a wiping sheet that can clean and sterilize shoe dirt without the need to rinse with water.

Summary of the Invention

Problems to be Solved by the Invention

[0006] By the way, due to the characteristics of the wiping and washing method, a certain amount of the components of the cleaning agent composition remains on the surface of the footwear. Utilizing this characteristic and blending a discoloration suppressing component such as an ultraviolet absorber into the cleaning agent composition is a useful attempt to prevent discoloration of the footwear. However, in conventional cleaning agent compositions, discoloration of the footwear surface, particularly of light-colored resin materials, may not be sufficiently suppressed.

Means for Solving the Problems

[0007] In view of the above issues, the present inventors conducted diligent research and found a cleaning composition that, when used for wiping and washing footwear, not only provides a cleaning effect but also effectively suppresses discoloration of the footwear, by using a combination of a surfactant and a specific ultraviolet absorber.

[0008] In other words, the present invention is as follows: [1] A cleaning agent composition for wiping and washing footwear, comprising a nonionic ultraviolet absorber and a surfactant. [2] The detergent composition according to [1], wherein the octanol / water partition coefficient of the ultraviolet absorber is 5 or more. [3] The detergent composition according to [1] or [2], wherein the mass ratio of the ultraviolet absorber to the surfactant is 1:4 to 12. [4] The cleaning agent composition according to any one of [1] to [3], wherein the footwear includes a sole made of urethane resin. [5] The detergent composition according to claim 1, which suppresses discoloration. [1] to [4] A method for disinfecting and cleaning footwear, characterized by wiping the surface of the footwear with the cleaning agent composition described in any one of [6][1] to [5]. A method for suppressing discoloration of footwear, characterized by wiping the surface of the footwear with a cleaning agent composition described in any one of [7][1] to [5]. [Effects of the Invention]

[0009] The cleaning agent composition for wiping and washing footwear according to the present invention does not require rinsing, and not only is it effective in cleaning, but it also suppresses discoloration of footwear. [Modes for carrying out the invention]

[0010] The cleaning agent composition for wiping and washing footwear of the present invention (hereinafter simply referred to as "the present invention composition") contains a nonionic ultraviolet absorber and a surfactant. The present invention composition is for wiping and washing, meaning that rinsing with water is not necessary for cleaning, and it only requires wiping.

[0011] The above-mentioned nonionic UV absorbers, i.e., UV absorbers that tend not to ionize in water, are not particularly limited, but examples include benzotriazole UV absorbers, cyanoacrylate UV absorbers, benzophenone UV absorbers, and hindered amine UV absorbers. Among nonionic UV absorbers, those with an octanol / water partition coefficient (also called Log P or LogPow) of 5 or higher are preferred, and those with an octanol / water partition coefficient of 6 to 10 are more preferred. Examples of nonionic UV absorbers having such an octanol / water partition coefficient include UV-328 (Log P: 7.3), octabenzone (Log P: 7.4), and benzotriazolyldodecyl p-cresol (Log P: 8.9). One or more of these nonionic UV absorbers can be used.

[0012] The octanol / water partition coefficient mentioned above is the ratio of the concentration of a substance in octanol to the concentration of a substance in water when the substance is dissolved in a mixture of octanol and water (20-25°C). It can be either a calculated or measured value. The formula for calculating the octanol / water partition coefficient is as follows:

[0013] [Mathematics 1] Octanol / water partition coefficient = Log10 (concentration of substance in the octanol layer / concentration of substance in the water layer)

[0014] In the composition of the present invention, the theoretical basis for the effectiveness of nonionic UV absorbers is not entirely clear. However, compared to ionic UV absorbers that easily ionize in water, nonionic UV absorbers exhibit a moderate tendency to be lipophilic, which may lead to the formation of a uniform UV absorber film, thereby effectively suppressing discoloration of footwear.

[0015] The content of the nonionic ultraviolet absorber in the composition of the present invention is not particularly limited, but is, for example, 0.05 to 0.5% by mass (hereinafter simply referred to as "%"), preferably 0.1 to 0.3%.

[0016] The surfactant is not particularly limited, and examples thereof include cationic surfactants, nonionic surfactants, anionic surfactants, amphoteric surfactants, and the like.
