Description

[Technical field]

[0001] The present invention relates to a detergent composition for textile products and a method for cleaning textile products. [Background technology]

[0002] Detergents containing surfactants are used to clean textile products such as clothing. In recent years, as consumers have become more conscious of hygiene, interest in bacteria on textile surfaces and stains derived from them has also increased, and studies have been conducted to impart bactericidal and disinfecting effects in addition to cleaning. Escherichia coli is often used as a criteria bacterium for evaluating bactericidal and disinfecting effects, and the number of Escherichia coli bacteria can be said to be an index of environmental hygiene. Therefore, it is thought that more hygienic textile products can be provided to consumers by killing bacteria including Escherichia coli when cleaning textile products. Furthermore, it is possible to improve consumers' sense of hygiene by simultaneously removing visible stains derived from bacteria.

[0003] Patent Document 1 discloses a liquid detergent composition for clothing, which comprises: component (A): a hydroxycarboxylic acid; component (B): at least one antibacterial agent selected from the group consisting of components (b-1), (b-2), and (b-3); and component (C): a nonionic surfactant, in which the content of component (A) is 5 mass% or more relative to the total mass of the liquid detergent composition for clothing, and the pH at 25°C is 2 to 6. Patent Document 2 discloses a cleaning composition for hard surfaces that contains an alkane bispyridinium as a quaternary ammonium salt, an alcohol ethoxylate having 10 carbon atoms (the number of moles of ethyleneoxy groups added is 5) as a nonionic surfactant, and citric acid as an acid agent, and has a pH of about 3.

[0004] [Patent Document 1] JP 2018-188641 A [Patent Document 2] European Patent Application Publication No. 3771338 Summary of the Invention [Problem to be solved by the invention]

[0005] However, it is difficult to kill E. coli using conventional sterilization techniques that use cationic surfactants known for use in cleaning textile products, and the removal of visible stains derived from bacteria is also insufficient. The present invention provides a detergent composition for textile products, which has an excellent bactericidal effect against bacteria including Escherichia coli and is also excellent in decolorizing bacterial stains attached to textile products, and a method for cleaning textile products. [Means for solving the problem]

[0006] The present invention relates to a detergent composition for fabric products, which contains the following components (a), (b), and (c), and water, and has a pH at 25° C. of 1 or more and 5 or less: Component (a): one or more compounds selected from the following components (a1), (a2), (a3), and (a4): (a1) Component: Quaternary ammonium salt (a2) Component: Alkylamine with 14 or more carbon atoms (a3) Component: Alkylamine oxide having 14 or more carbon atoms (a4) Component: Bispyridinium compound Component (b): a compound represented by the following general formula (b1): R 1b -O-(EO) n -H (b1) [In the formula, R 1b is a hydrocarbon group having 8 to 24 carbon atoms, EO is an ethyleneoxy group, and n is the average number of moles added, which is a number of 0 or more and less than 10. (c) Ingredient: Acid agent

[0007] The present invention also relates to a method for cleaning textile products, which comprises mixing the detergent composition for textile products of the present invention with water to obtain a cleaning liquid, and then cleaning the textile products with the cleaning liquid. Effect of the Invention

[0008] According to the present invention, there are provided a detergent composition for textile products, which has an excellent bactericidal effect against bacteria including Escherichia coli, and an excellent decolorization effect on bacterial stains attached to textile products, and a method for cleaning textile products.

[0009] <Cleaning composition for textile products> The reason why the detergent composition for textile products of the present invention has an excellent bactericidal effect against bacteria including E. coli and is excellent in decolorizing stains derived from bacteria attached to textile products is not entirely clear, but is presumed to be as follows. It is believed that the main components of the surface layer components of E. coli and the stains derived from bacteria attached to fibers are both polysaccharide components. In the detergent composition for textile products of the present invention, by making the pH acidic, the pH of the cleaning solution when diluted is also kept acidic, and when fibers with stains derived from bacteria are washed with the cleaning solution, it is possible to remove the pigment components contained in the bacteria. Furthermore, in the detergent composition for textile products of the present invention, it is believed that the bactericidal performance against E. coli is improved by allowing the specific (a) component and the specific (b) component to act under acidic conditions.
