An improved method for predicting stability of liquid detergent composition, identifying and designing liquid detergent compositions that provide said desired stability, consumer acceptance and performance.

Liquid laundry detergent compositions with improved stability and transparency

Acidic antimicrobial compositions for treating food surfaces and food contact surfaces comprise an organic acid and a surfactant, said composition having a pH of from about 2 to about 5. Concentrated, acidic antimicrobial compositions preferably comprise a stabilizing agent to prevent precipitation of the surfactant upon dilution of the concentrated composition. Methods of use comprise contacting food surfaces or food contact surfaces with the compositions of the present invention. Articles of manufacture comprise a container, an acidic antimicrobial composition, and a set of instructions in association with the container.

Acidic antimicrobial compositions for treating food and food contact surfaces and methods of use thereof

Basic cleaning compositions using toxicologically-acceptable ingredients for treating food such as produce, e.g., fruits and vegetables, and edible animal proteins are provided. Liquid formulations comprising, optionaly, less than about 0.5% detergent surfactat, such as potassium alkyl sulfate, that does not affect palatability and basic buffer to provide a pH of at least 10.5 are applied to food products immediately before consumption and allowed to stay for at least about one half minute to significantly reduce microorganism contamination. The food can be consumed without rinsing.

Microorganism reduction methods and compositions for food

Basic cleaning compositions using toxicologically-acceptable ingredients for treating food such as produce, e.g., fruits and vegetables, and edible animal proteins are provided. Liquid formulations comprising anionic and/or nonionic detergent surfactant, such as potassium alkyl sulfate, that does not affect palatability, electrolyte to provide at least about 0.04 molarity of cations and basic buffer to provide a pH of at least 8.5 are applied to food products immediately before consumption and can significantly reduce microorganism contamination in less than about one minute. The food can be consumed without rinsing.

Basic food cleaning compositions using food compatible ingredients for treating food such as produce, e.g., fruits and vegetables, and edible animal proteins are provided with specific non-substantive perfume. Liquid and solid powder formulations diluted with water also containing non-substantive perfume are applied to food products immediately before consumption and allowed to stay for at least about one half minute to significantly reduce microorganism contamination. With the preferred processes, the food can be consumed without rinsing.

Microorganism reduction methods and compositions for food cleaning

Basic cleaning compositions using toxicologically-acceptable ingredients for cleaning hard surfaces are provided. Compositions safe for use on surfaces which are contacted by food intended for ingestion by humans or lower animals, even when the compositions are incompletely removed from the cleansed surface, are described. Liquid formulations comprising surfactant, such as sodium alkyl sulfate, sodium alkylbenzene sulfonate, etc., and having a pH of above 11.6 are contacted directly onto hard surfaces to remove soil and unwanted deposits. Articles for applying the compositions to hard surfaces by spraying are disclosed.
