Cleaner for Hard Surfaces
The subject invention provides biosurfactants, as well as their use to, for example, efficiently clean contaminating and/or fouling substances such as paint, mold and algae from porous surfaces, and/or to enhance the cleaning of contaminants from non-porous surfaces.
1 . A cleaning composition comprising a sophorolipid and/or a mannosylerythritol lipid; lauramine oxide and a solvent selected from glycol ethers, dibasic esters, ketone solvents, ketal solvents, and terpenes.
2 - 6 . (canceled)
7 . The cleaning composition of claim 6 , comprising a glycol ether selected from monobutyl glycol, tributyl glycol, and tripropylene glycol methyl ether.
8 . The cleaning composition of claim 1 , comprising a dibasic ester selected from dialkyl adipate, dialkyl succinate, and dialkyl azelate.
9 . The cleaning composition of claim 1 , comprising a ketone solvent selected from acetone and methyl isobutyl ketone.
10 . The cleaning composition of claim 1 wherein the terpene is DL-limonene.
11 . The cleaning composition of claim 1 , further comprising an alkaline soap, an acid or a bleaching agent.
12 . A method for cleaning a contaminant from a surface, wherein the method comprises:
applying a cleaning composition comprising a glycolipid, a surfactant and a solvent to the surface; and removing the cleaning composition and the contaminant from the surface.
13 . The method of claim 12 , wherein the cleaning composition is applied to the surface by spraying.
14 . (canceled)
15 . The method of claim 13 , wherein the spraying is done using a pressurized spraying device, and wherein the composition is sprayed at a pressure of 1,000 psi to 7,000 psi.
16 - 20 . (canceled)
21 . The method of claim 12 , wherein removing the cleaning composition and contaminant comprises rinsing or spraying water onto the surface.
22 - 25 . (canceled)
26 . The method of claim 12 , wherein the surface is brick, ceramic, cinder block, stone, an aggregate panel, asphalt, untreated wood, sheetrock, drywall, plaster, stucco or porous plastic.
27 . The method of claim 12 , wherein the composition comprises a glycolipid selected from sophorolipids and mannosylerythritol lipids.
28 . The method of claim 12 , wherein the glycolipid concentration in the composition is from 100 ppm to 5 wt %.
29 . (canceled)
30 . The method of claim 12 , wherein the composition comprises lauramine oxide as a surfactant.
31 . The method of claim 12 , wherein the composition comprises a solvent selected from glycol ethers, dibasic esters, ketone solvents, terpenes, and water.
32 . The method of claim 31 , wherein the composition comprises a glycol ether selected from monobutyl glycol, tributyl glycol, and tripropylene glycol methyl ether.
33 . The method of claim 31 , wherein the composition comprises a dibasic ester selected from dialkyl adipate, dialkyl succinate, and dialkyl azelate.
34 . The method of claim 31 , wherein the composition comprises a ketone solvent selected from acetone and methyl isobutyl ketone.
35 . The method of claim 31 , wherein the terpene is DL-limonene.
36 . (canceled)
37 . The method of claim 12 , wherein the contaminant is paint, ink, dye, mold, algae, a food particle, or a microorganism.
