Abstract
A composition comprising tris-(hydroxymethyl)aminomethane and dicyclohexyl-, dicyclohexenyl- and cyclohexylcyclohexenyl-alkyl polyamines, their acid addition salts, and mixtures thereof are useful as antibacterial agents. The composition is particularly useful because of the synergistic improvement obtained against strains of the genus Pseudomonas, as well as other genera.
Claims24
An antibacterial composition comprising an admixture of 1 to 500 parts by weight of tris(hydroxylamine)methylamine for each part by weight of a polyamine having the formula:
- ##STR14## where A is alike or different cyclohexyl or cyclohexenyl of the formula:
- ##STR15## where each R is either hydrogen or C.sub.1 to C.sub.6 alkyl, and the dished line indicates a single obefinic bond;
- each n is alike or different and is the integer 0 or 1;
- each R.sub.1 is alike or different and is C.sub.1 to C.sub.4 alkylene;
- Z is ##STR16## where R.sub.5 is hydrogen, aminoethyl, aminopropyl, C.sub.1 to C.sub.4 hydroxyalkyl, or C.sub.2 to C.sub.4 dihydroxyalkyl;
- and
- R.sub.6 is hydrogen, C.sub.1 to C.sub.4 hydroxyalkyl or C.sub.2 to C.sub.4 dihydroxyalkyl;
- a. when Y is ##STR17## R.sub.2 is 2-hydroxy-1,3-trimethylene, or R.sub.1 as previously defined;
- R.sub.3 is hydrogen, C.sub.1 to C.sub.4 alkyl, C.sub.2 to C.sub.4 aminoalkyl, C.sub.1 to C.sub.4 hydroxyalkyl, or C.sub.2 to C.sub.4 dihydroxyalkyl;
- R.sub.4 is 2-hydroxy-1,3-trimethylene, or R.sub.1 as previously defined;

- and
- c. when Y is --R.sub.2 --, then R.sub.2, R.sub.5 and R.sub.6 are as previously defined, or acid addition salts thereof.
