    ODOR NEUTRALIZER INTENDED TO ELIMINATE THE EXISTING ODOR INSIDE A REFRIGERATORY DEVICE.
    The invention refers to the process comprising the use of a product in order to neutralize the bad smell immediately, produced in apparatus intended for cold food preservation.
    The use of the product is especially indicated when, as a result of a failure in the electricity supply, unforeseen defrosting of food in the freezer that causes its rot occurs.
    STATE OF THE TECHNIQUE
    There are some traditional disinfectant products, such as sodium hypochlorite and ammonia, which, although they perform their specific function of disinfecting, do not immediately eliminate the bad smell of the refrigerator without leaving it out of use for a long time.
    Other products, deodorizers, such as activated carbon and sodium bicarbonate, are used to absorb odors from products contained in refrigerators but do not fulfill the function of eliminating bad odors in extreme cases.
    In addition, other odor masking products are used, such as vinegar, lemon, coffee, air fresheners and perfumes that with their own fragrance reduce the intensity of bad odors.
    According to patent references with numbers ES 2 362 054 TE, ES 2 496 091 T3, ES 2 496 091 T3, the products: dimethylcyclohexyl, undecylenic acid or citric acid and some cysteine derivatives neutralize odors.
    Patents JP2008291176A, JP2002187803A, US6395698B1 and CN104436261 A, refer to deodorant compositions that include quaternary ammonium derivatives. It treats in a very general way its different applications without specifying the intensity of the bad smell, the times of stabilization of the mixtures, the
    5
    10

    concentrations to be applied or the application time on surfaces or when this time is specified is greater than 48 hours. This document does not describe the use of these products or their specific application to! extreme case of unforeseen defrosting, for several days, of the food contained in the freezer.
    Therefore, from what is known in the state of the art it follows that there is still an urgent need to find an effective product in the elimination of odors, in the event that as a result of a failure in the electricity supply, there is unforeseen defrosting of food in the freezer that causes its rot.
    EXPLANATION OF THE INVENTION
    The present inventors have found that the application of an aqueous solution of alkyldimethylbenzylammonium chloride, also commonly called banzalkonium chloride, in a certain concentration and over a certain period of time manages to completely eliminate the bad odors existing in the freezer.
    The aqueous solution of alkyldimethylbenzylammonium chloride used has a concentration that is highly effective and which is also adapted in its design to potential users,
    This procedure optimizes the use of the refrigeration device by achieving a record time of fifteen minutes, putting it into operation again.
    The same goes for the problem of contamination in the taste of the food introduced inside.
    This is the procedure for the use of alkyldimethylbenzylammonium to eliminate persistent bad odors caused by microorganisms (mold, mildew, etc.) and organic matter residues inside refrigerating and freezing appliances.
    While quaternary ammonium derivatives are sufficiently tested and tested worldwide in many applications, especially as

    disinfectants, it has been possible to verify the lack of a specific design in the use of them for cases of food rot inside the freezer, so that odors can be eliminated without leaving the characteristic residual smell of alkyldimethylbenzylammonium chloride
    For both reasons, it is understood the need to solve this problem of bad odors especially in domestic areas when there is a surge in the electricity network, or derivations of harmonics that circulate through it and as a result of the absence of the user of the domicile for a long time, for example during the holiday period, defrosting and rotting of food occurs inside the refrigeration appliances that is aggravated by its poor ventilation.
    On the other hand, and of vital importance, it is to obtain the solution that the time necessary to eliminate odors is the minimum possible to avoid the inoperativity of the apparatus, think for example that they are private homes and restaurants whose use is absolutely necessary. But not only this, if the odors can be eliminated quickly, contamination in the flavor of the new products introduced inside is avoided.
    The odor neutralizer is a solution of alkyl dimethylbenzylammonium chloride with a concentration between 1 and 7%, the solvent being water.
    Therefore, one aspect of the present invention is to provide a method for removing unhealthy odor from inside a refrigerating apparatus, characterized in that it comprises: a) applying an aqueous solution of alkyldimethylbenzylammonium chloride in a concentration between 1-7% in weight; b) maintain the impregnation for a period of time between 10-20 '; and c) remove the product by washing the walls of the refrigerator.
    In a particular embodiment of the above process, the concentration of the aqueous solution of alkyldimethylbenzylammonium chloride is between 2 and 4% by weight.
    In another particular embodiment of the above process, the concentration of the aqueous solution of alkyldimethylbenzylammonium chloride is 2.33% by weight.

    The solution can be applied directly to the inner surface of the refrigerator and freezer, using a trigger sprayer.
    In a particular embodiment, the actuation time is fifteen minutes with the apparatus closed and off.
    In another particular embodiment, product removal is carried out with a neutral soap and water.
    If necessary, the procedure can be repeated.
    Throughout the description and the claims the word "comprises" and its variants are not intended to exclude other technical characteristics, additives, components or steps. In addition, the word "comprises" includes the case "consists of." For those skilled in the art, other objects, advantages and features of the invention will be derived partly from the description and partly from the practice of the invention. Examples are provided by way of illustration, and are not intended to be limiting of the present invention In addition, the present invention covers all possible combinations of particular and preferred embodiments indicated herein.
    EXAMPLES
    The product consists of 2.33% alkyldimethylbenzylammonium chloride by weight. The performance was carried out in a domestic refrigerator full of food that ran out of electricity, whereby the entire contents of the refrigerator and freezer had rotten. The device gave off a foul smell.
