Abstract
There are provided antimicrobial compositions of the low toxicity having enhanced activity against gram positive and gram negative bacteria as well as fungi or protozoa and consists essentially of: (a) an alkyl-N-betaine in amounts up to 40 parts, by weight, (b) an alkyl-N,N-dimethylamine oxide, an alkyl-N,N-dihydroxy-ethylamine oxide, or an acylamido t-amine oxide in amounts up to 40 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 from about 4.0 to about 5.5. The composition exhibits skin degerming, cleansing, and deodorizing properties and, particularly, its use exhibits long term inhibition of body odor.
Claims16
A broad spectrum, antimicrobial composition having low toxicity which consists of:
- (a) from 0.1 to 40 parts, by weight, of a higher alkyl-N-betaine, said betaine having the structure:
- ##STR3## where R is a higher alkyl of from 10 to 18 carbon atoms, or mixed alkyl of the same,
- (b) from 0.1 to 40 parts, by weight, of a higher alkyl-N,N-dimethylamine oxide, a higher alkyl-N,N-dihydroxyethylamine oxide, or an acylamido t-amine oxide having the respective structure:
- ##STR4## where R.sub.1 is a higher alkyl of from 10 to 18 carbon atoms, or mixed alkyl of the same, and
- (c) a protonating agent, sufficient to adjust the pH of said composition from 4.0 to 5.5.
