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.
Claims11
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.
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.
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.
