Abstract
The present disclosure relates to rheology modified, low foaming aqueous antimicrobial compositions. The compositions are phase stable under acidic conditions, and do not need to be rinsed from the surface to which they are applied. The present disclosure further relates to methods of use thereof.
Claims19
A method for reducing a population of microorganisms on a surface comprising:
- (a) providing a single phase aqueous low foaming antimicrobial concentrate composition comprising:
- (i) at least about 25 wt % water;
- (ii) one or more of an alkyl sulfate, an alkyl sulfonate, and/or an alkyl aryl sulfonate antimicrobial agent;
- (iii) a defoaming agent;
- (iv) an acidulant;
- (v) a stabilizing agent;
- and
- (vi) a thickening agent,
- wherein the composition does not include a carboxylic acid;
- wherein the composition has a viscosity of between about 50 centipoise and about 3500 centipoise, and the thickening agent is present in an amount effective such that the composition is phase stable under acidic conditions;
- (b) diluting the composition;
- and
- (c) contacting the surface with the diluted composition such that the population of microorganisms is reduced, wherein the composition does not need to be rinsed from the surface.

A method for washing produce comprising:
- (a) contacting the produce with a phase stable aqueous acidic antimicrobial composition comprising:
- (i) at least about 25 wt % water;
- (ii) one or more of an alkyl sulfate, an alkyl sulfonate, and/or alkyl aryl sulfonate antimicrobial agent;
- (iii) a defoaming agent;
- (iv) an acidulant;
- (v) a stabilizing agent;
- and
- (vi) a thickening agent present in an amount effective such that the composition is phase stable under acidic conditions,
- wherein the composition does not include a carboxylic acid;
- wherein the composition is diluted prior to contacting and has a viscosity of between about 50 centipoise and about 3500 centipoise, and the produce does not need to be rinsed after being contacted by the composition.
