Cleaning composition

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.

What is claimed is: 
     
       1. 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 substntially 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.   
     
     
       2. Composition according to claim 1 in which the base oil is used in proportions of about 60 to 80%, the limonene type extract or distillate 20 to 35%, and the lubricant is about 2.0 to 3.5%. 
     
     
       3. Composition according to claim 1 in which the limonene product is a citrus distillate extract having a specific gravity of about 0.841, a refractive index of about 1.4719, and an aldehyde content not in excess of 0.5%. 
     
     
       4. A composition according to claim 3 in which the proportions of the limonene ingredient is about 26 to 27%. 
     
     
       5. A composition according to claim 1 in which the lubricant is present in proportions of 2.5 to 3.0% of the total. 
     
     
       6. A composition according to claim 1 in which the base oil comprises about 68 to 72% of the total, the limonene type material about 26 to 27%, and the lubricant about 2 to 3%. 
     
     
       7. A composition according to claim 1 in which the lubricant is lanolin. 
     
     
       8. A composition according to claim 1 in which the major portion of the composition is the base hydrocarbon oil, said oil being substantially odorless, the limonene ingredient is a toiletry grade extract, the lubricant is a refined lanolin and the surface active agent is a dialkyl alkali metal sulfs succinate. 
     
     
       9. A composition according to claim 1 in which the base oil is a deodorized paraffinic oil of the kerosene boiling range in proportions of about 70%, 26 to 27% of a soap grade limonene type extract from citrus peels, 2 to 3% of refined lanolin, and 0.5 to 1% of dioctyl sodium sulfasuccinate. .Iadd. 10. 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 60 to 80% 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 20 to 35% 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. about 2.0 to 3.5% of a skin lubricant; and   about 0.5 to 3% of a surface active agent to promote wetting of the contaminant by the composition.
