Definitions
- This invention is concerned with a mold remover product of peroxide type with excellent effects without an irritating odor and exhibiting excellent mold-removing and cleansing activities.
- the mold remover product of this invention is used to bleach mold that grows on the surfaces of household walls or furnishings.
- chlorine-type bleach has been used with the main component of sodium hypochlorite.
- the chlorine-type bleach is fraught with problems such as inducing unpleasant sensation to the user because of the specific odor of molecular chlorine generated and also the danger of poisoning the user by chlorine gas even if an excellent bleach activity is shown.
- organic chlorine compounds from the chlorine-type bleach. Therefore, there has been demand to develop bleach without using chlorine-type compounds from the viewpoint of prevention of environmental pollution.
- Japanese Patent Application Laid-open No. [Sho]-52-110287 described a bleach product composed of peroxide and cyanamide and/or a metal cyanamide to be used for bleaching fiber material, but the bleaching activity is not sufficient with mold.
- U.S. Patent No. 3,756,774 described a bleach product composed of peroxide and organic cyanide at pH 4-7 to be used for bleaching fiber material, but the bleaching activity is not sufficient with mold.
- Japanese Patent Application Laid-open No. [Sho]-62-1790 described a mold-removing product composed of peroxide and silicone oil and/or an emulsion thereof, but the bleaching activity is not sufficient with mold.
- Japanese Patent Application Laid-open No. [Sho]-62-149800 described the use of an alkali metal salt of cyanic acid as the activator of peroxide, but there is no description on the bleaching of mold.
- This invention offers a mold-removing product with excellent bleaching activity on mold that grows on household walls or furnishings, especially mold on the washbasin in the kitchen, on the bathroom walls and ceilings and on tile joints without an irritating odor. Also, a method is offered for the bleaching of mold.
- component (A) of this invention we use hydrogen peroxide or a peroxide that produces hydrogen peroxide in aqueous solution.
- an aqueous solution of hydrogen peroxide is preferably used.
- components (A) is used at 0.5-60 wt% in general, preferably at 0.5-30 wt%, most preferably at 0.5-10 wt%, or practically at 1-6 wt% in terms of hydrogen peroxide.
- a peroxide to produce hydrogen peroxide in water one can use a compound that is an adduct of hydrogen peroxide.
- the compound that is an adduct of hydrogen peroxide one can cite the sodium carbonate adduct of hydrogen peroxide at the molar ratio of 2:3 or sodium perborate hydrate or tetrahydrate.
- the amount used must be such that the hydrogen peroxide produced therefrom is within the range of concentration cited above.
- component (B) As the alkali metal salt of cyanic acid or ammonium salt of cyanic acid as component (B), one can cite potassium cyanate, sodium cyanate and ammonium cyanate, and one can use one or more such compounds.
- the content of component (B) in the product of this invention is 0.2-30 wt%, preferably 0.5-10 wt%, or most preferably 0.5-5 wt%.
- a commercially available salt of cyanic acid in solid form can be used.
- the content of peroxide as component (A) in the mold remover product of this invention is 0.5-60 wt% in general, preferably 0.5-30 wt%, or more preferably 0.5-10 wt%, or most preferably in practice 1-6 wt%.
- the content of the salt of cyanic acid as component (B) is 0.2-30 wt%, preferably 0.5-10 wt%, or most preferably 0.5-5 wt%. If the content of component (A) or (B) is less than these ranges, the bleaching activity becomes too low. If the content of component (A) or (B) is more than these ranges, the handling becomes difficult as the product for mold remover.
- the pH is important in the mold remover product of this invention to achieve excellent bleaching activity.
- the pH is usually 7-13, or preferably 8-13, or most preferably 9.0-12.4.
- pH of the product is less than this range, the bleaching activity becomes weak. If it is more than this range, the peroxide compound becomes unstable, so that it is difficult to handle as a mold-removing product.
- alkali metal hydroxide or alkali metal silicate salt in order to adjust pH of the mold remover product of this invention within the aforementioned range.
- alkali metal hydroxide or alkali metal silicate salt one can use the hydroxide of an alkali metal, such as lithium hydroxide, sodium hydroxide and potassium hydroxide, and the silicate salt of an alkali metal, such as sodium silicate and potassium silicate. It is preferable to use an alkali metal silicate salt such as sodium silicate or potassium silicate, as the bleaching activity is markedly improved.
- the content of alkali metal hydroxide or alkali metal silicate salt is in the range of 0.01-10 wt%, so that the pH of the mold remover product lies within the aforementioned range.
- the aqueous solution of these compounds are alkaline by themselves, so that the amount of the alkali metal hydroxide or alkali metal silicate salt used can be reduced.
- the mold remover product of this invention is prepared by dissolving (A) hydrogen peroxide or a compound that is an adduct of hydrogen peroxide and (B) an alkali metal salt of cyanic acid or ammonium salt of cyanic acid in water.
- the mold remover product of this invention can be a homogeneous aqueous solution or a slurry.
- the water content in the mold remover product of this invention is 40-99 wt%, preferably 50-98 wt%, or most preferably 60-97 wt% with respect to the whole product.
- surfactant as well to the mold remover product of this invention.
- a surfactant one can cite polyoxyethylene alkyl ethers, polyoxyethylene fatty acid esters and amine oxides as nonionic surfactants, or soaps, alkyl sulfate salts and alkylbenzenesulfonate salts as anionic surfactants. It is preferable to add the surfactant at 0.1-5 wt% in the mold remover product. By the addition of surfactant, permeation of the mold remover product into the mold is accelerated, resulting in enhanced effectiveness in the bleaching, washing and removal of mold.
- the mold remover product of this invention is used as a solution or as a slurry to be applied by spraying or by coating on the surface of household walls or furnishings that have mold. By this method, it is possible to bleach mold effectively.
- An aqueous solution of hydrogen peroxide, potassium cyanate and an aqueous solution of sodium metasilicate were added to water and mixed to attain the concentration of hydrogen peroxide at 3.0 wt%, of potassium cyanate at 5.0 wt% and of sodium metasilicate at 0.1 wt% to prepare a mold remover product. Its pH was 9.0.
- Mold remover products were prepared with altered components and contents as shown in Table I, where the term % indicated wt%.
- the pH of solution is shown in Table I.
- Mold remover products were prepared by using hydrogen peroxide adducts of sodium carbonate and sodium perborate hydrate instead of hydrogen peroxide.
- the content of the hydrogen peroxide adduct of sodium carbonate or sodium perborate hydrate was expressed in terms of the hydrogen peroxide contained in these substances.
- Table II shows the results of the mold bleaching test and the evaluation of odor using these products.
- a bleach product was prepared using sodium hypochlorite as shown in Table III.
- the term % indicates wt%.
- Table III shows the results of the mold bleaching test and the evaluation of odor carried out with the bleach products obtained. The pH of the products is also shown. The bleaching activity was excellent, but offensive odor of chlorine was marked.
- Bleach products were prepared as in Application Example 2, except for omitting a salt of cyanic acid. Table III shows the results; the bleaching activity was reduced.
- Bleach products were prepared as in Application Example 2, except for using tetraacetylethylenediamine instead of a salt of cyanic acid. Table III shows the results. The bleaching activity was somewhat reduced, and the strong odor of organic acid was perceived.
- Bleach products were prepared as in Application Example 4, except for using sodium hydroxide at 10%. Table III shows the results. The pH of solution was 13.7, and the bleaching activity was reduced.
- Bleach products were prepared similar to Application Example 10, except for omitting the use of a salt of cyanic acid. Table III shows the results. The bleaching activity was reduced. Appln. Example 1 2 3 4 5 6 7 8 9 10 Hydrgn. perox. 3% 3% 3% 3% 3% 3% 3% 3% 3% 1% 20% Potass. cyanate 5% 5% 5% 5% 5% 5% 1% 5% 10% Sodium cyanate 5% Sodium metasil. 0.1% 2.5% 0.5% 0.5% 3% Sodium orthosil. 0.5% 0.1% 0.1% 0.1% Sodium hydrox.
