Abstract

Ethyl benzyl quaternaries having superior anti-fungal properties versus their benzyl quaternary analogs. The ethylbenzyl amidoamine quaternaries of the present invention are easily produced without significant waste and with minimal capital, while possessing improved antimicrobial properties. These molecules are useful in a range of applications such as fungicides, personal care as treatments for acne, dandruff, psoriasis and other fungal skin born conditions, as well as in feminine products where an antifungal is required that is gentle on the sensitive tissues, as well as HIV prevention. These molecules are also excellent hair conditioners and laundry fabric softeners.
