Abstract
The present invention relates to a topical antimicrobial composition containing an antimicrobial complex that provides sustained antimicrobial disinfecting action upon contact with microorganisms for prolonged periods, without the necessity for reapplication. The topical antimicrobial composition provides both initial and residual contact-killing disinfecting activity, and does not release its antimicrobial components into contacting liquids at levels that result in solution disinfection.
Claims88
An antimicrobial composition comprising an organic, polycationic, polymeric, antimicrobial material that can bind non-leachably to a surface such that the antimicrobial material does not release biocidal amounts of leachables into a contacting solution.
A dermal antiseptic composition comprising an organic, polycationic, antimicrobial polymer that binds to skin upon application.
A method for enhancing the duration of efficacy of a dermal antiseptic formulation, the method comprising the step of:
- mixing a polycationic antimicrobial material and a dermal antiseptic formulation, such that the antimicrobial material is capable of forming a self-preserving, antimicrobial barrier upon application of the formulation to skin, thereby enhancing the antimicrobial efficacy of the antiseptic formulation by imparting residual antimicrobial activity.
A method for imparting moisture and sweat resistance to extend the duration of efficacy of a skin deodorant formulation, the method comprising the steps of:
- (i) providing a dermal deodorant formulation;
- and
- (ii) mixing a polycationic antimicrobial material in the deodorant formulation, wherein the antimicrobial material can form a moisture and sweat resistant antimicrobial barrier upon application of the formulation to skin, thereby providing deodorizing efficacy over extended periods.
