The invention claimed is: 1. An oil-in-water emulsion composition, comprising: (A) a solvent selected from the group consisting of naphtha, heavy aromatic naphtha, turpentine, toluene, xylene, methylene chloride, C9-C15 aromatic compounds, acetone, methyl ethyl ketone, N-methyl pyrrolidone, dimethy
The invention claimed is: 1. An oil-in-water emulsion composition, comprising: (A) a solvent selected from the group consisting of naphtha, heavy aromatic naphtha, turpentine, toluene, xylene, methylene chloride, C9-C15 aromatic compounds, acetone, methyl ethyl ketone, N-methyl pyrrolidone, dimethyl glutarate, dimethyl adipate, diethylene glycol monobutyl ether, and mixtures of two or more thereof; (B) water; (C) at least one surfactant selected from the group consisting of an oleyl alcohol 20-ethoxylate, dodecyl alcohol 12-15 ethoxylate, octyl alcohol 9-11ethoxylate and mixtures thereof; (D) at least one thickener selected from the group consisting of a hectorite clay, a smectite clay, and mixtures thereof; and (E) at least one base selected from the group consisting of potassium hydroxide, sodium carbonate, potassium acetate, dimethylethanolamine, triethanolamine, a polyamine enriched in triethylene tetramine, a polyamine enriched in tetraethylene pentamine, a polyamine enriched in pentaethylene hexamine and mixtures thereof; resulting in an emulsified remover; wherein said oil-in water emulsion composition is characterized by a continuous aqueous phase, and a discontinuous oil or solvent phase and wherein the oil-in-water emulsion composition is characterized by a dispersed oil phase comprising droplets having a mean diameter of about 0.05 to about 50 microns; and wherein said emulsion composition removes aqueous coatings, non-aqueous coatings, waxes and greases from substrates that such material is applied to; and wherein the solvent is present in the oil-in-water emulsion remover at a concentration in the range of about 20 to about 80% by weight of the emulsified composition, wherein the water is present in the oil-in-water emulsion remover at a concentration in the range from about 15 to about 75% by weight of the emulsified composition, wherein the concentration of the surfactant in the oil-in-water emulsion composition in the range from about 0.1 to about 10% by weight of the emulsified composition, wherein the thickener is present in the oil-in-water emulsion remover in a concentration up to about 5% by weight of the emulsified composition, and wherein the base is present in the oil-in-water emulsion remover at a concentration of up to about 60% by weight based on the weight of the water in the oil-in-water emulsion. 2. The composition of claim 1 further including at least one additive selected from the group consisting of antimisting agents, odor masks, corrosion inhibitors, coloring agents, antifungal agents, antimicrobial agents, antifreeze agents, and combinations thereof. 3. The composition of claim 1 wherein the oil-in-water emulsion composition has a Brookfield viscosity using a No. 3 spindle at 10 rpm up to about 100,000 centipose (cP) at 25째 C. 4. The composition of claim 1 wherein the total amount of solvent (A) present in the oil-in-water emulsion remover is selected from the group consisting of a concentration of, about 25% to about 60% by weight of the emulsified composition, and about 25% to about 45% by weight of the emulsified composition. 5. The composition of claim 1 wherein the solvent is selected from the group consisting of at least one of a heavy aromatic naphtha present in about 20 to about 40% by weight of the emulsified composition, a diethylene glycol monobutyl ether present in 2 to about 20% of the emulsified composition and combinations thereof. 6. The composition of claim 2 wherein the concentration of each of the additives may be independently up to about 10% by weight of the emulsified composition. 7. The composition of claim 1 wherein the oil-in-water emulsified composition is substantially free of a high viscosity xanthan gum. 8. The composition of claim 2 wherein one or more additives are selected from 1.) the antimisting agents selected from the group consisting of polyethylene glycol, polysaccharide gums, and copolymers of 2-acrylamido-2-methylpropane sulfonic acid, sodium salt (NaAMPS) with acrylamide and substituted acrylamides and combinations thereof; 2.) corrosion inhibitors selected from the group consisting of fatty acid derived alkanolamide, fatty acid derived imidazolines, metal and amine salts of organic acids, benzotriazole and tolyltriazole; odor masks include natural or synthetic aromatic compounds and combinations thereof; 3.) antifreeze agents selected from the group consisting of methanol, ethanol, ethylene glycol and propylene glycol and combination thereof; 4.) demulsifiers selected from the group consisting of polyethylene glycol, polyethylene oxides, polypropylene alcohol oxides (ethylene oxide-propylene oxide) polymers, polyoxyalkylene alcohol, alkyl amines, amino alcohol, diamines or polyamines reacted sequentially with ethylene oxide or substituted ethylene oxide mixtures, trialkyl phosphates, and combinations thereof; 5.) antifungals selected from the group consisting of sodium omadine and combination thereof; 6.) antimicrobials and preservatives selected from the group consisting of triazines, sodium omadine, zinc omadine, oxizolidines and imidazolines and combinations thereof; and 7.) combinations thereof. 9. A process to make the composition of claim 1 by mixing the solvent water, surfactant, thickener, base and optional additional additives under appropriate mixing conditions selected from the group consisting of high shear mixing, low shear mixing, or a combination thereof at a temperature in the range of about 0째 C., to about 100째 C., and for about 5 minutes to about 20 hours to form the desired oil-in-water emulsion composition. 10. The process of claim 9 wherein the mixing is at a shear rate for the mixing may be up to about 500,000 sec-1.
