Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
24 words
An antimicrobial composition which comprises an effective amount of β-bromo-β-nitrostyrene absorbed on a partially hydrolyzed starch with a DE value of 20 or less.
Claim 2
Dependent Claim
24 words
An antimicrobial composition which comprises an effective amount of β-bromo-β-nitrostyrene absorbed on a partially hydrolyzed starch with a DE value of 20 or less.
Claim 3
Dependent Claim
17 words
A composition according to claim 1 consisting essentially of 90-10% β-bromo-β-nitrostyrene and 10-90% of partially hydrolyzed starch.
Claim 4
Dependent Claim
16 words
A composition according to claim 2 consisting essentially of 50-25% β-bromo-β-nitrostyrene and 50-75% partially hydrolyzed starch.
Claim 5
Dependent Claim
15 words
A composition according to claim 3 wherein the DE value is from 5 to 15.
Claim 6
Dependent Claim
53 words
A process for combatting spoilage caused by the action of microorganisms in aqueous emulsion compositions normally subject to such spoilage, which comprises inhibiting said organism in such compositions with an effective inhibiting amount of a composition which comprises β-bromo-β-nitrosytrene absorbed on a partially hydrolyzed starch with a DE value of 20 or less.
Claim 7
Dependent Claim
53 words
A process for combatting spoilage caused by the action of microorganisms in aqueous emulsion compositions normally subject to such spoilage, which comprises inhibiting said organism in such compositions with an effective inhibiting amount of a composition which comprises β-bromo-β-nitrosytrene absorbed on a partially hydrolyzed starch with a DE value of 20 or less.
Claim 8
Dependent Claim
61 words
A process for combatting spoilage by the action of slime-forming algae, bacterial and fungi microorganisms in industrial cooling water and water used in pulp and paper manufacturing, which comprises inhibiting said slime-forming organism in such waters with an effective inhibiting amount of a composition which comprises β-bromo-β-nitrosytrene absorbed on a partially hydrolyzed starch with a DE value of 20 or less.
Claim 9
Dependent Claim
61 words
A process for combatting spoilage by the action of slime-forming algae, bacterial and fungi microorganisms in industrial cooling water and water used in pulp and paper manufacturing, which comprises inhibiting said slime-forming organism in such waters with an effective inhibiting amount of a composition which comprises β-bromo-β-nitrosytrene absorbed on a partially hydrolyzed starch with a DE value of 20 or less.
