Abstract
The present invention comprises a hard surface cleaning composition including an environmentally friendly alkyl amide solvent, derived from renewable bio-based resources that works at least as well as d-limonene. In one embodiment, the present invention is a cleaning composition including an anionic surfactant salt, a saturated C8 to C10 alkyl amide solvent, a cosolvent and water. The composition is substantially free of d-limonene and can remove red food soils with up to 20 percent protein, and also functions as an asphalt removal composition.
Claims20
A cleaning composition comprising:
- (a) C8 and/or C10 dimethyl alkyl amide solvent;
- (b) an anoinic surfactant,
- (c) a cosolvent;
- and
- (d) water, wherein said composition is essentially free of d-limonene.
An asphalt dissolving/hard surface cleaning/pot and pan pre-soak composition comprising:
- (a) a saturated di-methyl amide solvent;
- (b) an anoinic surfactant amide salt
- (c) a cosolvent, and
- (d) water, wherein said composition includes less than 0.05 wt. % of d-limonene.
A method of removing asphalt, red food or black oily soils from a surface, the method comprising:
- diluting a cleaner with water of dilution to form a use solution, wherein the cleaner comprises C8 and/or C10 dimethyl alkyl amide solvent;
- an anoinic surfactant salt, a cosolvent;
- and
- water, wherein said composition is essentially free of d-limonene;
- and
- contacting the surface with the use solution.
