Cleaning compositions for hard to remove organic material
First Claim
1. An aqueous cleaning composition, consisting of;
- a) at least one oxidizing agent in an amount of from about 2% to about 8% by weight based upon the total weight of said cleaning composition, said oxidizing agent is an inorganic peroxide or an organic peroxide or a salt thereof, a halogen compound, or an alkylating agent, or combinations thereof;
b) at least one hydrophilic surfactant having an HLB value of 10 to 20 in an amount of from about 2% to about 9.5% by weight based upon the total weight of said cleaning composition;
c) at least one hydrotrope surfactant comprising;
a modified carboxylate or a modified carboxylic acid or a salt thereof, an organic phosphate, an organic nitrogen containing compound which is an amino compound or a fatty quaternary amine alkoxylate, or an alkyl glucoside or an alkyl polyglucoside wherein said alkyl group contains from about 8 to about 16 carbon atoms, or combinations thereof, said hydrotrope having an HLB value of greater than 20 in an amount of from about 2.5% to about 12% by weight based upon the total weight of said cleaning solution;
d) at least one ultraviolet light analyzable phenol alkoxide surfactant in an amount of from about 1% to about 8% by weight based upon the total weight of said cleaning solution, said analyzable surfactant having an analyzable functional group capable of being analyzed at a wavelength from about 250 to about 290 nanometers; and
e) water.

Abstract
An oxidizing cleaning composition comprises a low concentration of aqueous hydrogen peroxide that is environmentally friendly and has good stability in strong alkaline solutions. The aqueous hydrogen peroxide composition contains a synergistic combination of one or more hydrophilic surfactants having an HLB of 10 or greater, one or more hydrotropes, one or more UV-analyzable surfactants having an aromatic detectable functional group, and optionally a surfactant having an HLB of less than 10. The cleaning composition when mixed with an alkaline compound is very effective in removing dried or baked residues of polymers, modified or natural celluloses starches, natural gels, and the like at low concentrations and temperatures.

6. A process for making a cleaning composition consisting of:
-
adding together in any order at least one oxidizing agent in an amount of from about 2% to about 8% by weight based upon the total weight of said cleaning composition, said oxidizing agent comprising an inorganic peroxide or an organic peroxide or a salt thereof, a halogen compound, or an alkylating agent, or combinations thereof; at least one surfactant having an HLB value of 10 to 20 in an amount of from about 2% to about 9.5% by weight based upon the total weight of said cleaning composition; at least one hydrotrope surfactant having an HLB value of greater than 20 in an amount of from about 2.5% to about 12% by weight based upon the total weight of said cleaning solution, wherein said hydrotrope surfactant is of a modified carboxylate or a modified carboxylic acid or a salt thereof, an organic phosphate, an organic nitrogen containing compound which is an amino compound or a fatty quaternary amine alkoxylate, or an alkyl glucoside or an alkyl polyglucoside wherein said alkyl group contains from about 8 to about 16 carbon atoms, or combinations thereof; at least one ultraviolet light analyzable phenol alkoxide surfactant in an amount of from about 1% to about 8% by weight based upon the total weight of said cleaning solution, said analyzable surfactant having an analyzable functional group capable of being analyzed at a wavelength from about 250 to about 290 nanometers; and water. - View Dependent Claims (7, 8, 9, 10)
