Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
98 words
A microbicidal solution suitable for a non-vented container, the microbicidal solution comprising: a) from about 0.2 to about 8% by weight hydrogen peroxide; b) from about 0.2 to about 11% by weight of an acid mixture consisting of peracetic acid and acetic acid; c) from about 0.5 to about 1.0% by weight of a sequestering agent; and d) the remainder of said solution being water; and wherein, the ratio of said acid mixture to hydrogen peroxide is between about 1.0 to about 11; wherein the hydrogen peroxide concentration of said solution is approximately 3% by weight or less.
Claim 2
Dependent Claim
98 words
A microbicidal solution suitable for a non-vented container, the microbicidal solution comprising: a) from about 0.2 to about 8% by weight hydrogen peroxide; b) from about 0.2 to about 11% by weight of an acid mixture consisting of peracetic acid and acetic acid; c) from about 0.5 to about 1.0% by weight of a sequestering agent; and d) the remainder of said solution being water; and wherein, the ratio of said acid mixture to hydrogen peroxide is between about 1.0 to about 11; wherein the hydrogen peroxide concentration of said solution is approximately 3% by weight or less.
Claim 3
Independent Claim
103 words
A method for sterilizing, disinfecting, or sanitizing a surface, said method comprising: contacting said surface with a dilute solution for use as a microbicide, the concentrate solution comprising: a) from about 0.2 to about 8% by weight hydrogen peroxide; b) from about 0.2 to about 11% by weight of an acid mixture consisting of peracetic acid and acetic acid; c) from about 0.5 to about 1.0% by weight of a sequestering agent; and d) the remainder of said concentrate solution being water; wherein, the ratio of said acid mixture to hydrogen peroxide is between about 1.0 to about 11 in said concentrate solution.
Claim 4
Independent Claim
103 words
A method for sterilizing, disinfecting, or sanitizing a surface, said method comprising: contacting said surface with a dilute solution for use as a microbicide, the concentrate solution comprising: a) from about 0.2 to about 8% by weight hydrogen peroxide; b) from about 0.2 to about 11% by weight of an acid mixture consisting of peracetic acid and acetic acid; c) from about 0.5 to about 1.0% by weight of a sequestering agent; and d) the remainder of said concentrate solution being water; wherein, the ratio of said acid mixture to hydrogen peroxide is between about 1.0 to about 11 in said concentrate solution.
