Abstract

There is provided an antimicrobial composition of low toxicity having enhanced gram positive and gram negative activity and consists essentially of: PA1 A. An alkylsubstituted alanine (0.1 part - 40.0 parts, by weight), PA1 B. an alkyl-N,N-dimethylamine oxide, an alkyl-N,N-dihydroxyethylamine or an acylamido t-amine oxide (0.1 part - 40.0 parts, by weight), and PA1 C. a protonating agent, such as hydrochloric acid, acetic acid or citric acid, in an amount sufficient to adjust the pH of the overall composition to about 5.5 or below. The composition exhibits skin degerming, cleansing, and deodorizing properties and, particularly, its use exhibits long term inhibition of body odor.
