Patent ID: 7566460

Claim:
A composition comprising: a) a hydroalcoholic solvent comprising a lower alcohol and water in a weight ratio of about 60:40 to about 100:0; b) a chlorhexidine salt; and c) at least one emulsifier in an amount of at least about 0.05% by weight, based on the total weight of the composition; wherein the emulsifier comprises: (i) at least one hydrophobic group selected from the group of: (A) an alkyl group of at least 24 carbon atoms; (B) an alkenyl group of at least 24 carbon atoms; and (C) an aralkyl or an aralkenyl group of at least 24 carbon atoms; and (ii) at least one hydrophilic group selected from the group of: (A) an ethylene oxide- and/or propylene oxide-containing group bonded to the hydrophobic group through an ether or ester bond and optionally terminated with a (C1-C36)alkyl ester, (C2-C36)alkenyl ester, or (C6-C36)alkaryl ester; (B) an alcohol group; (C) a polyhydric alcohol group; (D) an ester or ether group of a polyhydric alcohol or polyalkoxylated derivative thereof; (E) an ester or ether group of sorbitan or polyalkoxylated derivative thereof having 2-150 moles of alkylene oxide per mole of hydrophobic group; and (F) combinations thereof.
