ABSTRACT:
The present invention relates to a cleaning composition comprising an emulsion comprising a polar co-solvent, a non-polar co-solvent, and an alkylamine dispersed throughout the emulsion. The alkylamine serves to prevent the emulsion from inverting and forming a thick, slippery gel, which is known to interfere with the cleaning process and washing machine components. Further, the present invention relates to a method for preventing gel formation by adding an alkylamine to an emulsified cleaning composition and washing stained articles therein.In another aspect of the present invention a method for pre-treating a stained article is provided comprising applying a cleaning composition in the form of a gel comprising an emulsion of a polar co-solvent and a siloxane-based non-polar co-solvent, and a detergent to the article, allowing the cleaning composition to penetrate the stain; and laundering the article in a siloxane based cleaning composition comprising an alkylamine.
