Abstract
Abstract A composition and a process for making the same is provided wherein a chemical and storage stable pressure-sensitive adhesive has homogeneously dispersed therein a broad-spectrum antimicrobial agent. When the composition is placed in contact with the skin, it uniformly and controllably releases the broad-spectrum antimicrobial agent with substantially unaltered broad-spectrum antimicrobial activity.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
103 words
A process for making a dermatologically acceptable composition which controllably releases an antiseptically active broad-spectrum antimicrobial agent when placed in contact with skin comprising forming a solution of a broad-spectrum antimicrobial agent; forming a room temperature tacky pressure-sensitive adhesive which is compatible with said broad-spectrum antimicrobial agent; mixing said antimicrobial agent solution and said pressure-sensitive adhesive such that the broad-spectrum antimicrobial agent from said antimicrobial agent solution is homogeneously dispersed in said pressure-sensitive adhesive; and drying said homogeneous dispersion so as to remove said solvents leaving an antiseptically active amount of said broad-spectrum antimicrobial agent homogeneously and stably dispersed in said pressure-sensitive adhesive.
Claim 2
Dependent Claim
103 words
A process for making a dermatologically acceptable composition which controllably releases an antiseptically active broad-spectrum antimicrobial agent when placed in contact with skin comprising forming a solution of a broad-spectrum antimicrobial agent; forming a room temperature tacky pressure-sensitive adhesive which is compatible with said broad-spectrum antimicrobial agent; mixing said antimicrobial agent solution and said pressure-sensitive adhesive such that the broad-spectrum antimicrobial agent from said antimicrobial agent solution is homogeneously dispersed in said pressure-sensitive adhesive; and drying said homogeneous dispersion so as to remove said solvents leaving an antiseptically active amount of said broad-spectrum antimicrobial agent homogeneously and stably dispersed in said pressure-sensitive adhesive.
Claim 3
Dependent Claim
26 words
The process of claim 1 which includes the additional step of introducing a surfactant into said antimicrobial agent solution prior to mixing with said pressure-sensitive adhesive.
Claim 4
Dependent Claim
55 words
A composition which releases an antiseptically active broad-spectrum antimicrobial when placed in contact with skin comprising an antiseptically active amount of a broad-spectrum antimicrobial agent and a dermatologically acceptable room temperature tacky pressure-sensitive adhesive which is chemically compatible with said broad-spectrum antimicrobial, said broad-spectrum antimicrobial agent being homogeneously and stably dispersed in said pressure-sensitive adhesive.
Claim 5
Dependent Claim
55 words
A composition which releases an antiseptically active broad-spectrum antimicrobial when placed in contact with skin comprising an antiseptically active amount of a broad-spectrum antimicrobial agent and a dermatologically acceptable room temperature tacky pressure-sensitive adhesive which is chemically compatible with said broad-spectrum antimicrobial, said broad-spectrum antimicrobial agent being homogeneously and stably dispersed in said pressure-sensitive adhesive.
Claim 6
Dependent Claim
14 words
The composition of claim 3 wherein said antiseptically active broad-spectrum antimicrobial agent is chlorhexidine.
Claim 7
Dependent Claim
15 words
The composition of claim 3 wherein said antiseptically active broad-spectrum antimicrobial agent is polyvinylpyrrolidone-iodine complex.
Claim 8
Dependent Claim
63 words
A flexible backing material having attached thereto a composition which releases an antiseptically active broad-spectrum antimicrobial agent when placed in contact with skin comprising an antiseptically active amount of a broad-spectrum antimicrobial agent and a dermatologically acceptable room temperature tacky pressure-sensitive adhesive which is chemically compatible with said broad-spectrum antimicrobial agent, said antimicrobial agent being homogenously and stably dispersed in said pressure-sensitive adhesive.
Claim 9
Dependent Claim
63 words
A flexible backing material having attached thereto a composition which releases an antiseptically active broad-spectrum antimicrobial agent when placed in contact with skin comprising an antiseptically active amount of a broad-spectrum antimicrobial agent and a dermatologically acceptable room temperature tacky pressure-sensitive adhesive which is chemically compatible with said broad-spectrum antimicrobial agent, said antimicrobial agent being homogenously and stably dispersed in said pressure-sensitive adhesive.
Claim 10
Dependent Claim
16 words
The flexible backing material of claim 6 wherein said antiseptically active broad-spectrum antimicrobial agent is chlorhexidine.
Claim 11
Dependent Claim
17 words
The flexible backing material of claim 6 wherein said antiseptically active broad-spectrum antimicrobial agent is polyvinylpyrrolidone-iodine complex.
Claim 12
Dependent Claim
15 words
The flexible backing material and composition of claim 6 in the form of a drape.
Claim 13
Dependent Claim
15 words
The flexible backing material and composition of claim 6 in the form of a tape.
Claim 14
Dependent Claim
15 words
The flexible backing material and composition of claim 6 in the form of a dressing.
