Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
124 words
Method of treating a stainless steel surface comprising applying upon said surface a treating composition consisting essentially of an aqueous storage-stable emulsion of white mineral oil containing from about 20 to about 50 parts by weight white mineral oil having a Saybolt viscosity at 100° F. in the range of about 50 to about 380 Saybolt seconds, sufficient nonionic emulsion surfactant to produce said emulsion yet not so much surfactant as to leave a visible residue of same on the treated surface, and the balance of 100 parts being water, rubbing said surface to dislodge soil and wiping said surface to remove excess treating composition and removed soil, leaving on the treated surface a clear nonevaporating, even, non-streaked, thin film of white mineral oil.
Claim 2
Dependent Claim
124 words
Method of treating a stainless steel surface comprising applying upon said surface a treating composition consisting essentially of an aqueous storage-stable emulsion of white mineral oil containing from about 20 to about 50 parts by weight white mineral oil having a Saybolt viscosity at 100° F. in the range of about 50 to about 380 Saybolt seconds, sufficient nonionic emulsion surfactant to produce said emulsion yet not so much surfactant as to leave a visible residue of same on the treated surface, and the balance of 100 parts being water, rubbing said surface to dislodge soil and wiping said surface to remove excess treating composition and removed soil, leaving on the treated surface a clear nonevaporating, even, non-streaked, thin film of white mineral oil.
Claim 3
Dependent Claim
39 words
The method of claim 1 wherein said emulsion surfactant has an HLB of 2-8 and is selected from the group consisting of sorbitan fatty acid esters and polyglycerol esters of fatty acids and said emulsion is a water-in-oil emulsion.
Claim 4
Dependent Claim
44 words
The method of claim 1 wherein said emulsion surfactant has an HLB of 9-20 and is selected from the group consisting of ethoxylated fatty acid esters of anhydrosorbitol, polyglycerides of fatty acids and fatty acid alkanol amides and said emulsion is an oil-in-water emulsion.
Claim 5
Dependent Claim
25 words
The method of claim 1 wherein the quantity of said emulsion surfactant varies between about 0.5%-10% by weight of the total weight of said composition.
Claim 6
Dependent Claim
117 words
The method of claim 1 wherein said treating composition consists essentially of: A. 85 to 92 parts by weight of an aqueous emulsion of white mineral oil consisting of (1) 20 to 50 parts by weight white mineral oil having a Saybolt viscosity at 100° F. between about 50-380 Saybolt seconds; (2) 0.5 to 10 parts by weight sorbitan monooleate emulsification surfactant; (3) 0.1 to 2 parts by weight anti-corrosion agent selected from the group consisting of morpholine, monoethanolamine and sodium nitrite; (4) the balance to 100 parts by weight water; and B. 8 to 15 parts by weight liquified and normally gaseous compatible aerosol propellant material, contained in a suitable sealed vessel fitted with dispensing means.
