Abstract
Abstract A non-film forming, aqueous composition is disclosed for cleaning and for killing and inhibiting the regrowth of fungi and algae on a solid surface. The composition comprises a water-insoluble compound selected from the group consisting of a fungicide, an algicide and a mixture thereof dispersed in the composition, a detergent, a thickener, an oxidizing agent and water. Also disclosed is the composition in a two package form in which the oxidizing agent and at least a portion of the water are in one package, and the fungicide, algicide or mixture thereof, the detergent, the thickener, and optionally a portion of the water are in another package. Also disclosed is a process for cleaning a solid surface with the aqueous composition.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
98 words
A non-film forming, aqueous cleaning composition comprising: (a) from 0.1 to 0.4 percent by weight of said composition of 3- iodo-2-propynyl butyl carbamate; (b) from 1.0 to 6.0 percent by weight of said composition of a detergent; (c) a thickener present at a level sufficient that said composition has a viscosity at 25 degrees C. of between about 200 and about 4,000 centipoise; (d) an oxidizing agent which can provide an amount of chlorine to said composition, calculated as elemental C1, in a range of from 0.17 to 0.50 percent by weight of said composition; and (e) water.
Claim 2
Dependent Claim
98 words
A non-film forming, aqueous cleaning composition comprising: (a) from 0.1 to 0.4 percent by weight of said composition of 3- iodo-2-propynyl butyl carbamate; (b) from 1.0 to 6.0 percent by weight of said composition of a detergent; (c) a thickener present at a level sufficient that said composition has a viscosity at 25 degrees C. of between about 200 and about 4,000 centipoise; (d) an oxidizing agent which can provide an amount of chlorine to said composition, calculated as elemental C1, in a range of from 0.17 to 0.50 percent by weight of said composition; and (e) water.
Claim 3
Dependent Claim
32 words
The composition of claim 1 wherein said thickener is present at a level sufficient that said composition has a viscosity at 25 degrees C. of between about 350 and about 950 centipoise.
Claim 4
Dependent Claim
25 words
The composition of claim 1 having a pH in a range of from about 4.0 to about 8.5 prior to incorporation of said oxidizing agent.
Claim 5
Dependent Claim
53 words
The composition of claim 1 wherein said thickener is present at a level sufficient that said composition has a viscosity at 25 degrees C. of between about 350 and about 950 centipoise, and said composition prior to incorporation of said oxidizing agent has a pH in a range of from 6.0 to 8.5.
Claim 6
Dependent Claim
55 words
The composition of claim 1 wherein said composition is in the form of a two package composition in which said oxidizing agent and at least a portion of said water are in one package, and said fungicide, algicide and mixtures thereof, said detergent, said thickener, and a portion of said water are in another package.
Claim 7
Dependent Claim
153 words
A process for cleaning and for killing and inhibiting the regrowth of fungi and algae on a solid surface comprising: (1) applying to a solid surface a non-film forming, aqueous composition comprising (a) from 0.1 to 0.4 percent by weight of said composition of 3- iodo-2-propynyl butyl carbamate, (b) from 1.0 to 6.0 percent by weight of said composition of a detergent, (c) a thickener present at a level sufficient that said composition has a viscosity at 25 degrees C. of between about 200 and about 4,000 centipoise; (d) an oxidizing agent which can provide an amount of chlorine to said composition calculated as elemental C1 in a range of from 0.17 to 0.50 percent by weight of said composition, and (e) water; (2) allowing said composition to remain in contact with said surface for a time sufficient to at least partially clean said surface; and (3) rinsing said composition from said surface.
Claim 8
Dependent Claim
153 words
A process for cleaning and for killing and inhibiting the regrowth of fungi and algae on a solid surface comprising: (1) applying to a solid surface a non-film forming, aqueous composition comprising (a) from 0.1 to 0.4 percent by weight of said composition of 3- iodo-2-propynyl butyl carbamate, (b) from 1.0 to 6.0 percent by weight of said composition of a detergent, (c) a thickener present at a level sufficient that said composition has a viscosity at 25 degrees C. of between about 200 and about 4,000 centipoise; (d) an oxidizing agent which can provide an amount of chlorine to said composition calculated as elemental C1 in a range of from 0.17 to 0.50 percent by weight of said composition, and (e) water; (2) allowing said composition to remain in contact with said surface for a time sufficient to at least partially clean said surface; and (3) rinsing said composition from said surface.
Claim 9
Dependent Claim
28 words
The process of claim 6 wherein said composition has a pH in a range of from about 4.0 to about 8.5 prior to incorporation of said oxidizing agent.
Claim 10
Dependent Claim
53 words
The process of claim 6 wherein said thickener is present at a level sufficient that said composition has a viscosity at 25 degrees C. of between about 350 and about 950 centipoise, and said composition prior to incorporation of said oxidizing agent has a pH in a range of from 6.0 to 8.5.
Claim 11
Dependent Claim
