example

[0011] Soybean oil was maintained at a temperature of 350° C. in a layer of 3-4 mm on an aluminum pan for 24 hours. The resulting soil was an orange-brown substance with a rubbery consistency. The cleaning compositions described below were contacted with the soil at ambient temperature and the results were recorded in tabular form. The experiment under the double line is a comparative experiment.

Abstract

A method for removing polymerized soil by adding to the soil a composition which includes: (a) from 4 to 30 wt% of a hydroxide or alkoxide, (b) from 10 to 96 wt% of a C1-C12 primary alcohol; and (c) from 0 to 75 wt% of an organic solvent which is not a C1-C12 primary alcohol; wherein the composition contains no more than 40 wt% water.

Description

Background technique [0001] The present invention generally relates to a method for dissolving residues of polymerized soils, especially unsaturated triglycerides. [0002] Cleaners claimed to be effective in removing polymerized triglycerides have been reported, for example, in US Patent No. 8,246,696. However, known cleaning products do not effectively remove polymerized triglycerides. A composition capable of rapidly removing polymerized triglycerides would be a desirable product. Contents of the invention [0003] The present invention relates to a method for removing polymeric soil; said method comprises adding to said soil a composition comprising: (a) 4 to 30% by weight of a hydroxide or alkoxide, (b )10 to 96wt% of C 1 -C 12 primary alcohols; and (c) 0 to 75% by weight of 1 -C 12 An organic solvent for primary alcohols; wherein said composition contains not more than 40% by weight of water. detailed description [0004] All percentages are by weight unless o...
