Abstract
A sanitizer composition comprising a) an amine oxide having the formula: ##STR1## wherein the R.sub.1 groups are independently selected from C.sub.1 -C.sub.4 alkyl or alkoxy groups and R.sub.2 is a branched chain C.sub.11 -C.sub.16 alkyl group, and b) a quaternary ammonium compound having the formula: ##STR2## wherein the R.sub.3 groups are independently selected from C.sub.1 -C.sub.4 alkyl or alkoxy groups and the R.sub.4 groups are C.sub.8 -C.sub.16 linear or branched alkyl groups wherein at least one of the R.sub.4 groups is a branched C.sub.8 -C.sub.16 alkyl group, and X is chloride, bromide, iodide, carbonate or alkylcarboxylate having a C.sub.1 -C.sub.18 alkyl radical, and the use thereof.

A sanitizing composition comprising
- a) an amine oxide having the formula:
- ##STR5## wherein the R.sub.1 groups are independently selected from C.sub.1 -C.sub.4 alkyl or alkoxy groups and R.sub.2 is a branched chain C.sub.11 -C.sub.16 alkyl group, and
- b) a quaternary ammonium compound having the formula:
- ##STR6## wherein the R.sub.3 groups are independently selected from C.sub.1 -C.sub.4 alkyl or alkoxy groups and the R.sub.4 groups are C.sub.8 -C.sub.16 linear or branched alkyl groups wherein at least one of the R.sub.4 groups is a branched C.sub.8 -C.sub.16 alkyl group, and X is chloride, bromide, iodide, carbonate or alkylcarboxylate having a C.sub.1 -C.sub.18 alkyl radical;
- the weight ratio of said amine oxide and said quaternary ammonium compound being between about 10:1 and about 0.1:1.
A sanitizing composition that comprises
- a) isododecyldimethylamine oxide and
- b) decylisononyldimethylammonium chloride,
- wherein the concentration of compound (a) is between about 1% and 3% by weight, the concentration of compound (b) is between about 1% and about 60% by weight, and the weight ratio of (a) to (b) is between about 10:1 to about 0.1:1, said weight percents being based on the total weight of sanitizing composition.
A method of preventing the growth of microorganisms which comprises contacting said microorganisms with a sanitizing effective amount of a sanitizing composition comprising
- a) an amine oxide having the formula:
- ##STR7## wherein the R.sub.1 groups are independently selected from C.sub.1 -C.sub.4 alkyl or alkoxy groups and R.sub.2 is a branched chain C.sub.11 -C.sub.16 alkyl group, and
- b) a quaternary ammonium compound having the formula:
- ##STR8## wherein the R.sub.3 groups are independently selected from C.sub.1 -C.sub.4 alkyl or alkoxy groups and the R.sub.4 groups are C.sub.8 -C.sub.16 linear or branched alkyl groups wherein at least one of the R.sub.4 groups is a branched C.sub.8 -C.sub.16 alkyl group, and X is chloride, bromide, iodide, carbonate, or alkylcarboxylate anion having a C.sub.1 -C.sub.18 alkyl radical;
- the weight ratio of said amine oxide and said quaternary ammonium compound being between about 10:1 and about 0.1:1.
