US 6367488 B1Abstract
What is claimed is: 1. A method for cleaning produce comprising the step of contacting the surfaces of said produce with an aqueous cleaning solution comprising detergent surfactant selected from the group consisting of nonionic surfactant, C8-C18 fatty acid, salt of C8-C18 fatty acid, base-stable anionic surfactant, and mixtures thereof; neutralized ortho-phosphoric acid in an effective amount to provide removal of waxy materials; and a toxicologically-acceptable basic buffer selected from the group consisting of potassium carbonate, sodium carbonate, potassium bicarbonate, sodium bicarbonate, and mixtures thereof wherein said aqueous cleaning solution has a basic pH of greater than about 9.5.
(a) from about 0.01% to about 15% by weight of C8-C18 fatty acid; (b) optionally, from about 0.1% to about 4% by weight of said nonionic surfactant; (c) optionally, from about 0.1% to about 4% by weight of an organic polycarboxylic acid; (d) optionally, up to about 0.2% by weight of said base-stable anionic surfactant; (e) said toxicologically-acceptable basic buffer selected from the group consisting of potassium carbonate, sodium carbonate, potassium bicarbonate, sodium bicarbonate, and mixture thereof; (f) optionally, a toxicologically-acceptable preservative; (g) from about 0.05% to about 10% by weight of said neutralized ortho-phosphoric acid; and (h) the balance comprising an aqueous carrier selected from water and, optionally, a toxicologically-acceptable organic solvent; wherein said composition has a pH of more than about 9.5.
(a) from about 0.01% to about 15% by weight of C8-C18 fatty acid; (b) optionally, from about 0.1% to about 4% by weight of nonionic surfactant; (c) optionally, from about 0.1% to about 4% by weight of organic polycarboxylic acid; (d) optionally, up to about 0.2% by weight of base-stable anionic surfactant; (e) toxicologically-acceptable basic buffer selected from the group consisting of potassium carbonate, sodium carbonate, potassium bicarbonate, sodium bicarbonate, and mixtures thereof; (f) optionally, toxicologically-acceptable preservative; (g) from about 0.05% to about 10% by weight of phosphoric acid; and (h) the balance comprising an aqueous carrier selected from water and, optionally, low molecular weight, toxicologically-acceptable organic solvent; wherein said composition has a pH of more than about 9.5.
(a) at least about 0.75%, by weight, of a C12-C18 fatty acid or salt thereof; (b) at least about 0.05%, by weight, of a water-soluble polyethylene glycol having a molecular weight of about 200, or higher; (c) a water or water-ethanol fluid carrier, said composition having a basic pH. 7. A composition according to claim 3 wherein the pH of the composition is in the range from about 11.5 to about 12.3.
Glass flasks are coated with AP40 shellac and stress cured for 24 hours @ 140� F. The flasks at room temperature are then washed with ˜5 grams (5 squirts of a Calmar #TS-800 sprayer) of the respective products with a 10 sec. rub, followed immediately with a water rinse, and allowed to dry. The % Wax removal is determined gravimetrically.
