Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
116 words
A bactericidal composition comprising a bactericidal amount of a complex formed by mixing at a reactive temperature in a manner to cause intimate contact of the reactant with each other a reactive amount of a salt of an alkylamine, wherein the alkyl group contains between 8 and 18 carbon atoms, with a reactive amount of a nonionic surface active agent and with a bactericidal amount of a halogen which is iodine, bromine, chlorine or an interhalogen or iodine, bromine, fluorine, or chlorine, said complex characterized by (1) a negative reaction to standard starch iodine test for free halogen, (2) stability or no loss of halogen when boiled in an aqueous solution, and (3) having bactericidal activity.
Claim 2
Dependent Claim
116 words
A bactericidal composition comprising a bactericidal amount of a complex formed by mixing at a reactive temperature in a manner to cause intimate contact of the reactant with each other a reactive amount of a salt of an alkylamine, wherein the alkyl group contains between 8 and 18 carbon atoms, with a reactive amount of a nonionic surface active agent and with a bactericidal amount of a halogen which is iodine, bromine, chlorine or an interhalogen or iodine, bromine, fluorine, or chlorine, said complex characterized by (1) a negative reaction to standard starch iodine test for free halogen, (2) stability or no loss of halogen when boiled in an aqueous solution, and (3) having bactericidal activity.
Claim 3
Dependent Claim
11 words
The composition of claim 1 in which the halogen is iodine.
Claim 4
Dependent Claim
19 words
The composition of claim 2 in which the salt of the alkylamine is a salt of an organic acid.
Claim 5
Dependent Claim
19 words
The composition of claim 2 in which the salt of the alkylamine is a salt of an inorganic acid.
Claim 6
Dependent Claim
17 words
The composition according to claim 2 in which the salt of the alkylamine is an alkylamine sulfonate.
Claim 7
Dependent Claim
17 words
The composition according to claim 2 in which the salt of the alkylamine is an alkylamine sulfamate.
Claim 8
Dependent Claim
21 words
The composition of claim 5 in which the alkylamine sulfonate contains an average of between about 12 to 14 carbon atoms.
Claim 9
Dependent Claim
17 words
The composition of claim 1 in which the nonionic surface-active agent is an ethylene oxide condensation product.
Claim 10
Dependent Claim
19 words
The composition of claim 8 in which the condensation product contains between about 9 and 17 ethylene oxide units.
Claim 11
Dependent Claim
21 words
The composition of claim 2 in which further admixed therewith is a microbicidal amount of polymyxin, chlorotetracycline, oxytetracycline, chloramphenicol or penicillin.
Claim 12
Dependent Claim
16 words
The composition of claim 1 in which further admixed therewith is a microbicidal amount of formaldehyde.
