Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
58 words
A personal care or disinfectant product composition having an aldehyde in a thickened state comprising: (a) a low viscosity aldehyde; (b) a solvent in which the aldehyde is miscible selected from the group consisting of water and alcohols and mixtures thereof; and (c) a homopolymeric salt of 2-acrylamido-2-methylpropanesulfonic acid in an amount to sufficient to thicken the composition.
Claim 2
Dependent Claim
58 words
A personal care or disinfectant product composition having an aldehyde in a thickened state comprising: (a) a low viscosity aldehyde; (b) a solvent in which the aldehyde is miscible selected from the group consisting of water and alcohols and mixtures thereof; and (c) a homopolymeric salt of 2-acrylamido-2-methylpropanesulfonic acid in an amount to sufficient to thicken the composition.
Claim 3
Dependent Claim
19 words
The composition of claim 1 containing from about 0.25 percent to about 5 percent by weight of component (c).
Claim 4
Dependent Claim
21 words
The composition of claim 1 wherein component (b) is a lower alcohol containing from about 1 to about 4 carbon atoms.
Claim 5
Dependent Claim
19 words
The composition of claim 1 containing from about 5 percent to about 50 percent by weight of component (a).
Claim 6
Dependent Claim
19 words
The composition of claim 2 containing from about 0.4 percent to about 4 percent by weight of component (c).
Claim 7
Dependent Claim
10 words
The composition of claim 1 wherein component (b) is water.
Claim 8
Dependent Claim
10 words
The composition of claim 3 wherein component (b) is ethanol.
Claim 9
Dependent Claim
19 words
The composition of claim 1 wherein the aldehyde is selected from the group consisting of formaldehyde, acetaldehyde and glyoxal.
Claim 10
Dependent Claim
21 words
The composition of claim 1 wherein component (b) is present at from about 20 percent to about 80 percent by weight.
Claim 11
Dependent Claim
21 words
The composition of claim 1 wherein component (c) has a molecular weight of from about 1 million to about 5 million.
Claim 12
Dependent Claim
69 words
A process for disinfecting an article by applying a composition comprising: (a) a low viscosity aldehyde; (b) a solvent in which the formaldehyde is miscible selected from the group consisting of water and alcohols and mixtures thereof; and (c) a homopolymeric salt of 2-acrylamido-2-methylpropanesulfonic acid in an amount to sufficient to thicken the composition, wherein said article is disinfected through the slow release of the aldehyde in said composition.
Claim 13
Dependent Claim
69 words
A process for disinfecting an article by applying a composition comprising: (a) a low viscosity aldehyde; (b) a solvent in which the formaldehyde is miscible selected from the group consisting of water and alcohols and mixtures thereof; and (c) a homopolymeric salt of 2-acrylamido-2-methylpropanesulfonic acid in an amount to sufficient to thicken the composition, wherein said article is disinfected through the slow release of the aldehyde in said composition.
Claim 14
Dependent Claim
50 words
A disinfectant composition having formaldehyde in a thickened state comprising: (a) formaldehyde; (b) a solvent in which the formaldehyde is miscible selected from the group consisting of water and alcohols and mixtures thereof; and (c) a homopolymeric sale of 2-acrylamido-2-methylpropanesulfonic acid in an amount to sufficient to thicken the composition.
Claim 15
Dependent Claim
50 words
A disinfectant composition having formaldehyde in a thickened state comprising: (a) formaldehyde; (b) a solvent in which the formaldehyde is miscible selected from the group consisting of water and alcohols and mixtures thereof; and (c) a homopolymeric sale of 2-acrylamido-2-methylpropanesulfonic acid in an amount to sufficient to thicken the composition.
