Abstract
Antiseptic compositions comprising at least one salt of EDTA are disclosed. These compositions have broad spectrum antimicrobial and antifungal activity and they also have anticoagulant properties. The antiseptic compositions have also demonstrated activity in penetrating and breaking down microbial slime, or biofilms. They are safe for human and medical uses and may be used as prophylactic preparations to prevent infection, or to reduce the proliferation of and/or eliminate existing or established infections.
Claims31
An antiseptic composition comprising at least one salt of ethylene diamine tetraacetic acid (EDTA) at a concentration of at least 1.0% (w/v) having at least four of the following properties:
- anticoagulant properties;
- inhibitory and/or bactericidal activity against a broad spectrum of bacteria in a planktonic form;
- inhibitory and/or fungicidal activity against a spectrum of fungal pathogens;
- inhibitory and/or bactericidal activity against a broad spectrum of bacteria in a sessile form;
- inhibitory activity against protozoan infections;
- inhibitory activity against Acanthamoeba infections;
- safe and biocompatible, at least in modest volumes, in contact with a patient;
- safe and biocompatible, at least in modest volumes, in a patient's bloodstream;
- and safe and compatible with industrial objects and surfaces.
An antiseptic composition comprising at least one sodium EDTA salt in an aqueous solvent at a concentration of between 1.5% and 15% EDTA salt(s) (w/v) and having a pH of at least 8.5.
A method for inhibiting the growth and proliferation of microbial populations and/or fungal pathogens on a surface or object, comprising contacting the surface or object with a sanitizing composition comprising at least one salt of EDTA at a concentration of at least 1.0% (w/v).
A method for inhibiting the growth and proliferation of Acanthamoeba organisms on a surface or object, comprising contacting the surface or object with a sanitizing composition comprising at least one salt of EDTA at a concentration of at least 1.0% (w/v).
A method for substantially eradicating a broad spectrum of microbial populations, comprising contacting an infected object or surface with a sanitizing composition comprising at least one EDTA salt, in solution, at a concentration of at least 1.0% (w/v).
A method for inhibiting the growth and proliferation of microbial populations on a medical device, comprising contacting a surface of the medical device with a sanitizing composition comprising at least one EDTA salt, in solution, at a concentration of at least 1.0% (w/v).
