Abstract
A deodorant composition is made up of an oxygen carrying element associated with a synergistic odor-masking compound, and a biodegradable emulsifying surfactant. It can be used in the form of an emulsion or of the two separate constituents, and applicable to deodorizing organic or vegetal wastes and byproducts which normally release nauseating or harmful odors essentially made up of nitrogen or sulfur derivatives.
Claims7
A deodorizing composition consisting essentially of an aqueous mixture of an oxygen generating compound, an odor masking agent, and an emulsifying effective amount of a biodegradable emulsifying surfactant, wherein the oxygen generating compound is hydrogen peroxide at a concentration expressed at 100% H.sub.2 O.sub.2 of 50 to 500 g/liter of said aqueous mixture, the odor masking agent is a pine oil or the sesquiterpenes of turpentine, present in a concentration of 50 to 400 ml/l of said aqueous mixture, and the emulsifying surfactant concentration is 5 to 50 g/l of said aqueous mixture.
A deodorizing composition consisting essentially of an aqueous mixture of an oxygen generating compound, an odor masking agent, and an emulsifying effective amount of a biodegradable emulsifying surfactant, wherein the oxygen generating compound and masking agent are mixed at the time of use, the oxygen generating compound being hydrogen peroxide solution in a concentration between 30 and 50% hydrogen peroxide corresponding to 330 to 600 g/liter of 100% H.sub.2 O.sub.2, and the masking agent being a pine oil or the sesquiterpenes of turpentine made self emulsifying by incorporation of a polyoxyethylene type surfactant introduced in an amount of 1 to 10% surfactant per liter of masking agent said surfactant constituting from 10 to 100 g/liter.
A process for the treatment of normally fermenting animal wastes, including hog, calf or poultry manure, to inhibit the odors normally emanating therefrom, comprising mixing with said fermented waste from 0.1 to 1 liter of hydrogen peroxide solution in a concentration between 30 and 50% hydrogen peroxide corresponding to 330 to 600 g/liter of 100% H.sub.2 O.sub.2 and 0.1 to 1 liter of a masking agent which is pine oil or sesquiterpenes of turpentine made self emulsifying by incorporation of a polyoxyethylene type surfactant introduced in an amount of 1 to 10% surfactant per liter of masking agent said surfactant constituting from 10 to 100 g/liter.
