Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
30 words
A stabilized, aqueous, peroxide-containing composition comprising water, a peroxide selected from the group consisting of hydrogen peroxide and urea peroxide and from about 0.1 to about 2 percent lignin sulfonate.
Claim 2
Dependent Claim
30 words
A stabilized, aqueous, peroxide-containing composition comprising water, a peroxide selected from the group consisting of hydrogen peroxide and urea peroxide and from about 0.1 to about 2 percent lignin sulfonate.
Claim 3
Dependent Claim
13 words
The composition of claim 1 additionally containing an effective, stabilizing amount of EDTA.
Claim 4
Dependent Claim
16 words
The composition of claim 2 additionally containing an effective, stabilizing amount of a nontoxic magnesium salt.
Claim 5
Dependent Claim
34 words
A stabilized aqueous, peroxide-containing plant food composition comprising plant nutrients, water, a peroxide selected from the group consisting of hydrogen peroxide and urea peroxide, and from about 0.1 to about 2 percent lignin sulfonate.
Claim 6
Dependent Claim
34 words
A stabilized aqueous, peroxide-containing plant food composition comprising plant nutrients, water, a peroxide selected from the group consisting of hydrogen peroxide and urea peroxide, and from about 0.1 to about 2 percent lignin sulfonate.
Claim 7
Dependent Claim
13 words
The composition of claim 4 additionally containing an effective, stabilizing amount of EDTA.
Claim 8
Dependent Claim
16 words
The composition of claim 5 additionally containing an effective, stabilizing amount of a nontoxic magnesium salt.
Claim 9
Dependent Claim
43 words
A stabilized aqueous, peroxide-containing plant food composition comprising plant nutrients, water, a peroxide selected from the group consisting of hydrogen peroxide and urea peroxide, and from about 0.1 to about 4 percent of a composition comprising a lignin sulfonate, EDTA and magnesium sulfate.
Claim 10
Dependent Claim
43 words
A stabilized aqueous, peroxide-containing plant food composition comprising plant nutrients, water, a peroxide selected from the group consisting of hydrogen peroxide and urea peroxide, and from about 0.1 to about 4 percent of a composition comprising a lignin sulfonate, EDTA and magnesium sulfate.
Claim 11
Independent Claim
38 words
A method for stabilizing an aqueous, peroxide-containing composition wherein the peroxide is selected from the group consisting of hydrogen peroxide and urea peroxide, comprising combining the peroxide-containing composition with from about 0.1 to about 2 percent lignin sulfonate.
Claim 12
Independent Claim
38 words
A method for stabilizing an aqueous, peroxide-containing composition wherein the peroxide is selected from the group consisting of hydrogen peroxide and urea peroxide, comprising combining the peroxide-containing composition with from about 0.1 to about 2 percent lignin sulfonate.
Claim 13
Dependent Claim
18 words
The method of claim 8 wherein the composition is additionally combined with an effective, stabilizing amount of EDTA.
Claim 14
Dependent Claim
21 words
The method of claim 9 wherein the composition is additionally combined with an effective, stabilizing amount of a nontoxic magnesium salt.
Claim 15
Independent Claim
50 words
A method for stabilizing an aqueous peroxide-containing plant food composition, wherein the peroxide is selected from the group consisting of hydrogen peroxide and urea peroxide, comprising combining the peroxide-containing plant food composition with from about 0.1 to about 4 percent of a composition comprising lignin sulfonate, EDTA and magnesium sulfate.
Claim 16
Independent Claim
50 words
A method for stabilizing an aqueous peroxide-containing plant food composition, wherein the peroxide is selected from the group consisting of hydrogen peroxide and urea peroxide, comprising combining the peroxide-containing plant food composition with from about 0.1 to about 4 percent of a composition comprising lignin sulfonate, EDTA and magnesium sulfate.
