Antimicrobial compositions and methods for using the same
First Claim
1. A method for cleansing an animal, comprising administering to the area to be cleansed an antimicrobial composition comprising:
- (a) benzalkonium chloride, as an antimicrobial agent, present in an amount of from 0.05-5 weight percent of said antimicrobial composition;
(b) allantoin, present in an amount of about 0.05-5 weight percent of said antimicrobial composition;
(c) about 0.1-20 weight percent surfactant, which is not the same as the antimicrobial agent, comprising at least one nonionic, cationic or amphoteric surfactant; and
(d) at least about 60 weight percent water.

Abstract
Antimicrobial compositions useful in the treatment of microbial infections and as general cleansers are provided along with methods for their administration. The antimicrobial compositions are aqueous based and preferably contain a quaternary ammonium compound as a antimicrobial agent. The antimicrobial compositions also preferably contain a surfactant such as a cationic, nonionic, or amphoteric surfactant or mixtures thereof. A keratolytic agent, such as allantoin, is also preferably blended into the antimicrobial compositions. The antimicrobial compositions are ideally suited for subcutaneous, cutaneous, or mucosal membrane administration.
