Abstract
Abstract An aerosol cookware lubricant composition, which comprises a vegetable oil solution of an emulsifier (e.g., lecithin) in admixture with a hydrocarbon propellant, is adapted for visually-directed uniform application by incorporating therein a limited but significant concentration of particles of white flour or white starch together with a sufficient amount of fumed silica to prevent the flour from causing container packing or valve clogging, as well as minimizing spray billowing.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
137 words
An aerosol cookware lubricant composition adapted for visually-directed uniform application, said composition being in the form of a single liquid phase composed essentially of vegetable oil solution of an emulsifier in admixture with a propellant, wherein the improvement comprises having present in said composition from 2 to 15% of insoluble white particles selected from the class consisting of white flour, or white starch particles, or mixtures thereof, and from 0.5 to 2.0% of fumed silica, said composition containing from 10 to 40% of a hydrocarbon propellant selected from the class consisting of isobutane, n-butane, propane, and mixtures thereof, said composition containing from 2 to 20% by weight of water-dispersible lecithin, said percentages being by weight and being based on the total weight of said composition, the vegetable oil in said composition being liquid at normal use temperatures.
Claim 2
Dependent Claim
137 words
An aerosol cookware lubricant composition adapted for visually-directed uniform application, said composition being in the form of a single liquid phase composed essentially of vegetable oil solution of an emulsifier in admixture with a propellant, wherein the improvement comprises having present in said composition from 2 to 15% of insoluble white particles selected from the class consisting of white flour, or white starch particles, or mixtures thereof, and from 0.5 to 2.0% of fumed silica, said composition containing from 10 to 40% of a hydrocarbon propellant selected from the class consisting of isobutane, n-butane, propane, and mixtures thereof, said composition containing from 2 to 20% by weight of water-dispersible lecithin, said percentages being by weight and being based on the total weight of said composition, the vegetable oil in said composition being liquid at normal use temperatures.
Claim 3
Dependent Claim
173 words
An aerosol cookware lubricant composition adapted for visually-directed uniform application, said composition being in the form of a single liquid phase composed essentially of vegetable oil solution of lecithin in admixture with a propellant, said composition containing from 2 to 20% of said lecithin and from 50 to 75% of said vegetable oil together with an amount of said propellant effective for aerosol spraying of said composition, wherein the improvement comprises having present in said composition from 2 to 10% of insoluble white particles selected from the class consisting of white flour, or white starch particles, or admixtures thereof, and from 0.5 to 2.0% of fumed silica, said composition containing at least 3% hydroxylated lecithin, said propellant being a hydrocarbon propellant selected from the class consisting of isobutane, n-butane, propane, and mixtures thereof, and the amount thereof being limited to 20 to 30% of said composition, said percentages being by weight and being based on the total weight of said composition, the vegetable oil in said composition being liquid at normal use temperatures.
Claim 4
Dependent Claim
173 words
An aerosol cookware lubricant composition adapted for visually-directed uniform application, said composition being in the form of a single liquid phase composed essentially of vegetable oil solution of lecithin in admixture with a propellant, said composition containing from 2 to 20% of said lecithin and from 50 to 75% of said vegetable oil together with an amount of said propellant effective for aerosol spraying of said composition, wherein the improvement comprises having present in said composition from 2 to 10% of insoluble white particles selected from the class consisting of white flour, or white starch particles, or admixtures thereof, and from 0.5 to 2.0% of fumed silica, said composition containing at least 3% hydroxylated lecithin, said propellant being a hydrocarbon propellant selected from the class consisting of isobutane, n-butane, propane, and mixtures thereof, and the amount thereof being limited to 20 to 30% of said composition, said percentages being by weight and being based on the total weight of said composition, the vegetable oil in said composition being liquid at normal use temperatures.
Claim 5
Dependent Claim
46 words
The composition of claim 2 in which said lecithin comprises a mixture of 3 to 10% of hydroxylated lecithin together with 3 to 10% of lecithin in a non-water dispersible form, said percentages being by weight and being based on the total weight of said composition.
Claim 6
Dependent Claim
17 words
The composition of claim 2 or claim 3 in which said white particles are white wheat flour.
Claim 7
Dependent Claim
166 words
The aerosol cookware lubricant composition adapted for visually-directed uniform application, said composition being in the form of a single liquid phase composed essentially of vegetable oil solution of lecithin in admixture with a hydrocarbon propellant selected from the class consisting of isobutane, n-butane, propane, and mixtures thereof, said vegetable oil being soybean oil and being present in an amount of from 50 to 75%, said lecithin being present in an amount of from 8 to 16%, and said hydrocarbon propellant being present in an amount of from 20 to 30%, said composition being further characterized by having present therein from 2 to 10% of insoluble white particles selected from the class consisting of white flour, or white starch particles, or mixtures thereof, and from 0.5 to 2.0% of fumed silica, said composition containing at least 3% of hydroxylated lecithin, said percentages being by weight and being based on the total weight of said composition, the vegetable oil in said composition being liquid at normal use temperatures.
Claim 8
Dependent Claim
