DESCRIPTION:
BRIEF SUMMARY
This application is a 371 of PCT/JP95/01717 filed Aug. 30, 1995.
TECHNICAL FIELD
The present invention relates to a peroxide mold removal composition which has superior strength with respect to removing mold and does not have an irritating odor.
BACKGROUND OF THE INVENTION
In order to bleach the mold adhered to the walls and furniture in homes, chlorine bleaching in which sodium hypochlorite is used as the main component has been conventionally used. However, although chlorine bleaching agents have a superior bleaching strength, there are disadvantages including providing discomfort to the user due to the peculiar odor generated by the molecular chlorine as well as concerns regarding the toxic effects of chlorine gas, depending on the method of use. Furthermore, there is the concern that chlorine bleaching agents form environmentally undeniable organic chlorine compounds as by-products. Accordingly, switching to a bleaching agent that does not use a chlorine compound is desired.
In order to remove soil adhered to the walls and furnishings in a home, particularly the kitchen sink and bathroom walls, ceiling and tiles, a strong removing or bleaching function with respect to mold is necessary. However, molds manifest strong resistance with respect to conventional bleaching agents; thus, completely bleaching the mold is very difficult compared to bleaching fabrics, etc. Namely, peroxide bleaching agents such as hydrogen peroxide, inorganic peroxides, organic peroxides, etc., used independently have weak bleaching strength with respect to molds, and it is difficult to bleach the molds completely with them.
With regard to improvements in the bleaching action of peroxide bleaching agents, various proposals have been made. In Japanese Kokai Patent glucose pentaacetate, tetraacetylethylenediamine, tetraacetylglycoluril, cyanamide, etc., as activating agent with an oxygen bleaching agent is disclosed. However, the disclosed compositions containing an activating agent have problems with the bleaching strength, with respect to molds not being strong enough, compounds with irritating odors being created as by-products by the reaction with hydrogen peroxide and not being suited for practical application. composition for fabric bleaching agent composed of a peroxide and cyanamide and/or a metal cyanamide is disclosed, but the bleaching strength is not strong enough with respect to molds. In U.S. Pat. No. 3,756,774, a composition for a fabric bleaching agent with a pH of 4-7 containing organic cyanides and peroxides is disclosed, but the bleaching strength with respect to molds is not sufficient. In Japanese Kokai Patent peroxide and silicone oil and/or emulsifier is disclosed, but the bleaching strength with respect to molds is not sufficient.
SUMMARY DISCLOSURE OF INVENTION
The objective of said invention is to provide a mold removal composition having superior bleaching strength with respect to molds adhered to walls and furnishing in homes, particularly, kitchen sinks and bathroom walls, ceiling and tiles, and a bleaching method for said molds. As a result of earnest research, said inventors found that a composition of a peroxide and dicyandiamide manifests extremely high bleaching strength with respect to molds and does not have an irritating odor.
BEST MODE FOR CARRYING OUT THE INVENTION
As the peroxide used as component (A) of said invention, commercially available hydrogen peroxide aqueous solutions can be used favorably. The blending amount of the hydrogen peroxide aqueous solution in the mold removal composition of the present invention is generally 0.5-60 wt %, preferably 0.5-30 wt %, and more preferably 0.5-10 wt %. For practicality, 1-6 wt % is most favorable.
Also, it is possible to use as the peroxide a compound that forms an adduct with hydrogen peroxide and forms hydrogen peroxide insitu in an aqueous solution. As the compound that forms an adduct with hydrogen peroxide, sodium percarbonate, which is obtained by adding sodium carbonate and hydrogen peroxide in a 2:3 molar ratio, sodium perbora
