Abstract
There is provided an antimicrobial composition of low toxicity having enhanced gram positive and gram negative activity and consists essentially of: A. An alkylsubstituted alanine (0.1 part - 40.0 parts, by weight), 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 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.
Claims8
A broad spectrum, antimicrobial composition having low toxicity which consists essentially of:
- a. 0.1 to 40 parts, by weight, of a higher alkylsubstituted alanine having the structure:
- 1 RNHCH.sub.2 CH.sub.2 COOH, or
- 2 RN(CH.sub.2 CH.sub.2 COOH).sub.2
- where R is a higher alkyl of from 10 to 18 carbon atoms,
- b. 0.1 to 40 parts, by weight, of (1) a higher alkyl-N,N-dimethylamine oxide, (2) a higher alkyl-N,N-dihydroxyethylamine oxide, or (3) an acylamido t-amine oxide having the respective structure:
- ##STR2## where R.sub.1 is a higher alkyl of from 10 to 18 carbon atoms, or mixtures of the same, and
- c. a protonating agent, sufficient to adjust the pH of said composition from 4 to 6.0.
