Abstract
Abstract The composition disclosed consists primarily of a hydrocarbon oil of approximately the kerosene boiling range, preferably deodorized, in proportions of 5 to 92% by weight, preferably about 60 to 80%, based on the total composition, a limonene type solvent oil in proportions of 5 to 90%, preferably 20 to 35%, about 0.5 to 6% of lanolin or equivalent wool grease lubricating agent for the skin, and about 0.5 to 2.0% of a surface active agent, preferably of the aerosol type, such as "Aerosol OT" or equivalent.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
179 words
A composition for removing contaminating resinous, gummy or tarry residues from surfaces without adversely affecting paints or varnishes, said composition being substantially non-irritating to the skin and eyes of human beings, which comprises, in combination, the following ingredients in weight proportions, as indicated, based on the weight of the whole composition: A. about 5 to 92% of a base hydrocarbon oil of substantially the boiling range of kerosene, which is substantially free of objectionable odor and having not more than 5% of sulfonatable constituents, B. about 5 to 90% of a limonene type citrus distillate having high solvency for the contaminant and having a refractive index between about 1.4718 and 1.4722 at 20° C., with a specific gravity between about 0.838 and 0.843, having a resin content not more than about 0.10% and aldehyde content not in excess of about 0.90%, C. 0.5 to 6.0% of a skin lubricant selected from the class which consists of lanolin and wool grease, and D. 0.5 to 3% of a surface active agent to promote wetting of the contaminant by the composition.
