1. An antimicrobial hand wash comprising:
- i. an active ingredient selected from the group consisting of phenolic compounds, and mixtures thereof; and
ii. a cationic surfactant selected from the group consisting of lauramidopropyl dimethylamine, cocamidopropyl dimethylamine, or ricinoleamidopropyl dimethylamine, neutralized with an acid selected from the group consisting of citric acid, glutaric acid, oxalic acid, sulfuric acid, hydrochloric acid, glycolic acid, malic acid, itaconic acid, nicotinic acid, benzoic acid, acetylsalicylic acid, serine, boric acid, formic acid, propionic acid, succinic acid, adipic acid, lactic acid, and mixtures thereof.

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.
