Abstract
An antimicrobial hand wash comprises an active ingredient and an amidoamine based cationic surfactant having a fatty chain with from 6 to 24 carbon atoms. These cationic surfactants are compatible with common active ingredients such that antimicrobial efficacy is maintained, while foam quality is improved when the hand wash is dispensed as foam. Other antimicrobial hand washes include specific amidoamine based cationic surfactants that dissolve at least a portion of the active ingredient, thus reducing the amount of solids in the formulation, and, in some instances, making a cold manufacturing process possible.
