Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
138 words
A method of preparing a sprayable pan release product comprising mixing lecithin and a tri-glycol ester having fatty acid chains of from 6 to 12 carbon atoms at a temperature sufficient to form a solution thereof, cooling the mixture to about 90° F., adding thereto an alcohol, said alcohol being present in an amount of about 20% to about 25% of the weight of said product, said lecithin being present in the range of about 5% to about 30% with the remainder being a member selected from the class consisting of said tri-glycol ester and a mixture of said tri-glycol ester and a second tri-glycol ester having fatty acid chains of from 16 to 18 carbon atoms, and thereafter placing the mixture in a mechanical dispensing container whereby dispensing is achieved without the use of an aerosol propellant.
Claim 2
Independent Claim
138 words
A method of preparing a sprayable pan release product comprising mixing lecithin and a tri-glycol ester having fatty acid chains of from 6 to 12 carbon atoms at a temperature sufficient to form a solution thereof, cooling the mixture to about 90° F., adding thereto an alcohol, said alcohol being present in an amount of about 20% to about 25% of the weight of said product, said lecithin being present in the range of about 5% to about 30% with the remainder being a member selected from the class consisting of said tri-glycol ester and a mixture of said tri-glycol ester and a second tri-glycol ester having fatty acid chains of from 16 to 18 carbon atoms, and thereafter placing the mixture in a mechanical dispensing container whereby dispensing is achieved without the use of an aerosol propellant.
Claim 3
Dependent Claim
20 words
The method of claim 1 in which said lecithin is derived from soybeans and contains less than 3% soybean oil.
Claim 4
Dependent Claim
14 words
The method of claim 1 in which said lecithin contains about 40% soybean oil.
Claim 5
Dependent Claim
34 words
The method of claim 3 in which a second tri-glycol ester having fatty acid chains of from 16 to 18 carbon atoms is added subsequent to the addition of the first mentioned tri-glycol ester.
