Abstract
A film-forming composition containing a broad spectrum antimicrobial as an antimicrobial agent. The composition forms a film which is a substantially fluid-resistant, substantially tack-free, flexible film which adheres to skin and releases the antimicrobial agent to skin. A method of using the film-forming composition is also disclosed.
Claims26
A film-forming composition, comprising:
- (a) a film-forming copolymer consisting essentially of copolymerized A, B and C monomers as follows:
- A is a monomeric acrylic or methacrylic acid ester of an alkyl alcohol containing a single hydroxyl, said alcohol having from 2 to about 14 carbon atoms when said A monomer is an acrylic acid ester, and 7 to 18 carbon atoms when said A monomer is a methacrylic acid ester, the amount by weight of A monomer being about 15 to 80% of the total weight of all monomers in the copolymer;
- B is a monomeric methacrylic acid ester of an alkyl alcohol containing a single hydroxyl, said alcohol having from 1 to 6 carbon atoms, the amount by weight of B monomer being about 20 to 70% of the total weight of all monomers in the copolymer;
- and
- C is an N-vinyl lactam, the amount by weight of which being about 1 to 15% of the total weight of all monomers in the copolymer;
- (b) an effective amount of a broad spectrum antimicrobial agent;
- said composition being dermatologically-acceptable, and, when applied to skin from a fugitive solvent, being capable of forming a clear, substantially fluid-resistant, substantially tack-free, flexible film which adheres to skin and releases said antimicrobial agent to skin.
