Claims
- 1. A method useful for removing grease from a substrate, comprising: applying a degreasing composition to a grease on a substrate in an amount and under conditions effective to remove at least a portion of the grease from the substrate, wherein the composition comprises a carbonate and an alkyl-substituted cyclo-alkane, and optionally a soy carbonate, wherein the carbonate is a alkylene carbonate, a dialkyl carbonate, or combination thereof.
- 2. The method of claim 1, wherein the carbonate is an alkylene carbonate containing from 2 to 10 carbon atoms.
- 3. The method of claim 1, wherein the carbonate is propylene carbonate or ethylene carbonate or both.
- 4. The method of claim 1, wherein the carbonate is ethylene carbonate or propylene carbonate.
- 5. The method of claim 1, wherein the composition further comprises a glycol ether.
- 6. The process of claim 5, wherein the glycol ether is present in an amount in the range from about 5 to about 75 percent by weight based on the combined weight of the carbonate, the alkyl-substituted cyclo-alkane, and the glycol ether.
- 7. The method of claim 1, wherein the composition further comprises a glycol ether having up to 20 carbon atoms.
- 8. The method of claim 1, wherein the composition further comprises a mono-ester.
- 9. The method of claim 8, wherein the mono-ester includes an ether group.
- 10. The method of claim 1, wherein the soy carbonate is present.
- 11. The method of claim 1, wherein the composition further comprises an alkyl lactate.
- 12. The process of claim 11, wherein the alkyl lactate is present in an amount in the range from about 5 to about 75 percent by weight based on the combined weight of the carbonate, the alkyl-substituted cyclo-alkane, and the alkyl lactate.
- 13. The process of claim 1 wherein the alkyl-substituted cyclo-alkane comprises methylcyclopentane, 1,1-dimethylcyclopentane, 1,2-dimethylcyclopentane, 1,3-dimethylcyclopentane, ethylcyclopentane, n-propylcyclopentane, methylcyclohexane, 1,1-dimethylcyclohexane, 1,2-dimethylcyclohexane, 1,3-dimethylcyclohexane, ethylcyclohexane, cyclooctane, or a mixture thereof.
- 14. The process of claims 1, wherein the composition further comprises an alkyl acetate of oxo alcohol.
- 15. The process of claim 14, wherein the alkyl acetate of oxo alcohol is present in an amount from about 5 to about 75 percent by weight based on the combined weight of the carbonate, the alkyl-substituted cyclo-alkane, and the alkyl acetate of oxo alcohol.
- 16. The process of claim 1, wherein the composition further comprises an alkyl soyate.
- 17. The process of claim 16, wherein the alkyl soyate is methyl soyate.
- 18. The process of claim 16, wherein the alkyl soyate is present in an amount in the range from about 5 to about 75 percent by weight based on the combined weight of the carbonate, the alkyl-substituted cyclo-alkane, and the alkyl soyate.
- 19. The process of claim 1, wherein the soy carbonate is present in an amount in the range from about 5 to about 75 percent by weight based on the combined weight of the carbonate, the alkyl-substituted cyclo-alkane, and the soy carbonate.
- 20. The process of claim 1, wherein the alkyl-substituted cyclo-alkane is present in an amount in the range from about 5 to about 75 percent by weight based on the total weight of the composition.
- 21. The process of claim 1, wherein the carbonate is present in an amount in the range from about 5 to about 75 percent by weight based on the combined weight of the composition.
- 22. The process of claim 1, wherein the composition contains from about 0.1 to about 50 percent by weight of the carbonate, from about 0.1 to about 50 percent by weight of the alkyl-substituted cyclo-alkane, and the soy carbonate is present and in an amount for from about 0.1 to about 20 percent by weight.
- 23. The process of claim 1, wherein the substrate is made of metal, glass, concrete, or wood.
