Abstract
A method of treating a surface so that the antimicrobial activity of water-soluble antimicrobial agents is retained at the surface despite repeated washing with water is described. The method uses a dispersion of a lipidated polyanionic molecule and one or more antimicrobial agents in an aqueous carrier such as water. The treatment of the surface of the fabric of adhesive bandages and stainless steel is demonstrated using a combination of crystal violet and silver nitrate as the antimicrobial agents. The method has application in the treatment of such surfaces to control microbial growth and the development of biofilms.
Claims15
A method of treating a surface comprising the steps of:
- (a) contacting the surface with a lipidated polyanionic molecule dispersed in a solution of one or more water-dispersible antimicrobial agents;
- and then
- (b) drying the surface,
- where the antimicrobial activity of the one or more water-dispersible antimicrobial agents is retained at the surface when the surface is contacted with an aqueous vehicle.
A composition consisting essentially of a water-soluble salt of hexamethylpararosaniline, a water-soluble salt of silver, a lipidated polyanionic molecule and water.
