Abstract
An antimicrobial composition comprising: a complex of an anionic polyester with an antimicrobial cationic surfactant, wherein the anionic polyester has at least one carboxylic group. A medical device having an antimicrobial composition comprising: a complex of an anionic polyester with an antimicrobial cationic surfactant wherein the anionic polyester has at least one carboxylic group.
Claims8
An antimicrobial composition comprising:
- an ionic salt complex of an anionic polyester with lauric arginate, where the anionic polyester has the formula:
- wherein x is between 5 and 190, y is between 5 to 190, and x+y≦200.
A method of making an ionic salt complex of an anionic polyester of the formula:
- wherein x is between 5 and 190, y is between 5 to 190, and x+y≦200, with lauric arginate, comprising the step of incorporating an effective amount of the lauric arginate with the anionic polyester in an aqueous soluble alcohol.
