Abstract
A composition that includes ethylhexyl sulfate or a salt thereof, an alkylbenzenesulfonic acid or a salt thereof, and a carrier. The ethylhexyl sulfate, or salt thereof, and the alkylbenzenesulfonic acid, or salt thereof, are present in a weight ratio of at least about 1:2. The composition can be used for killing or inhibiting a microorganism or pathogen (e.g., bacteria, gram-negative bacteria, gram-positive bacteria, enteric bacteria, virus, fungus, mold, mildew or powdery mildew).
Claims28
A method of killing or inhibiting a microorganism or a pathogen, the method comprising contacting the microorganism or the pathogen with an effective amount of a composition comprising:
- (a) ethylhexyl sulfate of the formula
- or a salt thereof;
- and
- (b) an alkylbenzenesulfonic acid of the formula
- or a salt thereof, wherein n is about 5 to about 20;
- and
- (c) a carrier comprising water;
- wherein the ethylhexyl sulfate, or salt thereof, and the alkylbenzenesulfonic acid, or salt thereof, are present in a weight ratio such that based upon a weight basis, the amount of ethylhexyl sulfate, or salt thereof, is at least 100% that of the alkylbenzenesulfonic acid, or salt thereof, and is no more than 300% of the alkylbenzenesulfonic acid, or salt thereof;
- wherein the composition further comprises at least one of sodium hydroxide and potassium hydroxide such that the pH of the composition contacting the microorganism or pathogen is above about 6;
- wherein the composition does not comprise chlorine dioxide;
- for a period of time effective to kill or inhibit the microorganism or the pathogen.
A method of washing a plant, the method comprising contacting the plant with an effective amount of a composition comprising:
- (a) ethylhexyl sulfate of the formula
- or a salt thereof;
- and
- (b) an alkylbenzenesulfonic acid of the formula
- or a salt thereof, wherein n is about 5 to about 20;
- and
- (c) a carrier comprising water;
- wherein the ethylhexyl sulfate, or salt thereof, and the alkylbenzenesulfonic acid, or salt thereof, are present in a weight ratio such that based upon a weight basis, the amount of ethylhexyl sulfate, or salt thereof, is at least 100% that of the alkylbenzenesulfonic acid, or salt thereof, and is no more than 300% of the alkylbenzenesulfonic acid, or salt thereof;
- wherein the composition further comprises at least one of sodium hydroxide and potassium hydroxide such that the pH of the composition contacting the microorganism or pathogen is above about 6;
- wherein the composition does not comprise chlorine dioxide;
- for a period of time effective to wash the plant.
