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 C 8 to C 10 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.

First claim

What is claimed is:

1. A cleaning composition consisting of:
(a) from 12 wt. % to about 30 wt. % of a C 8 and/or C 10 dimethyl alkyl amide solvent;
(b) an anionic surfactant;
(c) a cosolvent, wherein the cosolvent is a glycol ether;
(d) at least one neutralizing agent;
(e) a chelant;
(f) a pH adjuster; and
(g) water.

2. The cleaning composition of claim 1 wherein said C 8 and/or C 10 dimethyl alkyl amide is saturated.

3. The cleaning composition of claim 1 wherein said anionic surfactant is a salt.

4. The cleaning composition of claim 3 wherein said salt is an amine salt.

5. The cleaning composition of claim 1 , wherein the anionic surfactant is present in an amount between about 5 wt. % and about 40 wt. % of the cleaning composition.

6. The cleaning composition of claim 1 , wherein the chelant is present in an amount between about 0.01 wt. % to about 15 wt. % of the cleaning composition.

7. The cleaning composition of claim 1 wherein said cleaning composition is a pot and pan pre-soaking composition, a hard surface cleaner or an asphalt dissolving composition.

8. An asphalt dissolving/hard surface cleaning/pot and pan pre-soak composition consisting of:
(a) from 13 wt. % to about 30 wt. % of a saturated C 8 and/or C 10 dimethyl alkyl amide solvent;
(b) an anionic surfactant amine salt;
(c) a cosolvent, wherein the cosolvent is a glycol ether;
(d) a neutralizing agent;
(e) a chelant;
(f) a pH adjuster; and
(g) water.

9. The cleaning composition of claim 8 , wherein the anionic surfactant is present in an amount between about 10 wt. % and about 35 wt. % of the cleaning composition.

10. The cleaning composition of claim 8 , wherein the chelant is present in an amount between about 0.01 wt. % to about 15 wt. % of the cleaning composition.

11. The cleaning composition of claim 8 , wherein the cleaning composition has a pH of between about 6.5 and about 10.
