Liquid cleaning compositions

摘要

A cleaning composition according to one embodiment includes a surfactant system comprising a nonionic surfactant in combination with an anionic surfactant; water present in an amount from 0 to about 40 wt % based on a total weight of the cleaning composition; a solvent system comprising a polyalcohol, the solvent system being present in an amount effective to solubilize the surfactant system in the water; and an enzyme present in an amount of less than about 15 wt %; wherein the cleaning composition is in a form of a water-in-oil emulsion, wherein the cleaning composition is characterized as exhibiting about a constant cleaning efficacy as measured using test procedure ASTM D4265 when the cleaning composition is added to 69 liters of exterior water in amounts ranging from about 9 to about 22 grams of cleaning composition. Methods for pretreating and cleaning laundry and nontextile surfaces are also presented.

1. A cleaning composition, comprising:
a surfactant system comprising:
a nonionic surfactant present in an amount from 15 to 60 wt % based on a total weight of the cleaning composition, andan anionic surfactant present in an amount from 15 to 55 wt % based on the total weight of the cleaning composition,wherein the surfactant system comprises invert micelles; total water present in an amount from greater than 0 to less than or equal to 40 wt % based on the total weight of the cleaning composition; a solvent system comprising a polyalcohol, the solvent system being present in an amount from 1.5 to 55 wt % based on the total weight of the cleaning composition; and an enzyme present in an amount greater than 0 to less than or equal to 15 wt % based on the total weight of the cleaning composition, wherein the cleaning composition is in a form of a water-in-oil emulsion, wherein the cleaning composition is characterized as exhibiting about a constant cleaning efficacy when the cleaning composition present in an amount from about 9 to about 22 grams is added to 69 liters of exterior water, wherein the constant cleaning efficacy corresponds to a % stain removal that varies by less than about 10%.
