Abstract
Abstract A composition of matter possessing powerful germicidal, antiseptic, fungicidal and bacteriacidal properties and a method of preparing the same are disclosed. The claimed method of manufacture permits the incorporation of iodine, urea or an iodophore or any combination thereof in the lipoidal, non polar, liquid aqueous phase of a two phase liquid aqueous system thereby producing the said composition of matter. The claimed composition can be prepared across a range of pH values extending from 3.4 to 7.5 without any significant loss of stability or germicidal, antiseptic, fungicidal and bacteriacidal activity.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
102 words
A method of preparing a composition of matter which possesses antiseptic, bacteriacidal, germicidal fungicidal and viricidal properties and which comprises the following steps: (a) preparing a two phase liquid aqueous system wherein one phase is a lipoidal, non polar liquid aqueous phase, herein also referred to as the coacervate phase and the second phase is an equilibrium water phase; (b) separating the coacervate phase from the equilibrium water phase; and (c) dissolving an agent effective against pathogenic micro-organisms in the coacervate phase; wherein the agent is selected from the group consisting of iodine in either crystalline or liquid form, iodophores and urea.
Claim 2
Independent Claim
102 words
A method of preparing a composition of matter which possesses antiseptic, bacteriacidal, germicidal fungicidal and viricidal properties and which comprises the following steps: (a) preparing a two phase liquid aqueous system wherein one phase is a lipoidal, non polar liquid aqueous phase, herein also referred to as the coacervate phase and the second phase is an equilibrium water phase; (b) separating the coacervate phase from the equilibrium water phase; and (c) dissolving an agent effective against pathogenic micro-organisms in the coacervate phase; wherein the agent is selected from the group consisting of iodine in either crystalline or liquid form, iodophores and urea.
Claim 3
Dependent Claim
40 words
The method of claim 1 which comprises the additional step of adding urea to the two phase liquid aqueous system and wherein the active agent is selected from the group consisting of iodine in crystalline or liquid form and iodophores.
Claim 4
Dependent Claim
20 words
The method of claim 1 wherein the two phase liquid aqueous system is prepared by using a surface active agent.
Claim 5
Dependent Claim
28 words
The method of claim 1 wherein the two phase liquid aqueous system is prepared by using a component selected from the group consisting of acacia and gelatin complexes.
Claim 6
Dependent Claim
23 words
The method of claim 1 wherein the two phase liquid aqueous system is prepared by using from 1 to 10% of a surfactant.
Claim 7
Dependent Claim
19 words
The method of claim 1 wherein the product of step (c) can range in pH from 3.4 to 7.5.
Claim 8
Dependent Claim
22 words
The method of claim 3 wherein the surfactant used is selected from the group consisting of benzylknoium chloride and sodium dioctyl sulphosuccinate.
Claim 9
Dependent Claim
23 words
A composition of matter prepared according to the method of claim 1 which is useful as an antiseptic, germicide, bacteriacide, fungicide and viricide.
