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.
Claims7
A method for cleaning a hard surface, comprising:
- diluting a cleaning composition from about a 1:1 to about a 1:8 ratio with water to form a use solution, the cleaning composition consisting of:
- from 12 wt. % to about 30 wt. % of a C8 and/or C10 dimethyl alkyl amide solvent, wherein the dimethyl alkyl amide solvent is N,N-dimethylcaprylamide, N,N-dimethylcapramide, or a mixture thereof;
- at least one neutralizing agent;
- a chelant;
- a pH adjuster;
- an anionic surfactant;
- a cosolvent, wherein the cosolvent is a dipropylene glycol ether;
- and
- water,
- contacting the surface with the use solution,
- wherein organic soils, food soils, lard, grease, food oil, protein, petroleum deposits, mineral spirits, oily soil, mineral oil, motor oil, oil dag, bandy black clay, and/or asphalt are removed from the hard surface.
