Refers to a process to increase the stability to oxidation of a composition comprising omega-6 polyunsaturated fatty acids, which comprises the following steps: (i) provide a starting composition which comprises at least one component Fatty Acid omega-6 polyunsaturated (R (i) provide a Composition of lysine (iii) mixed Aqueous SolutionsAqueous - Alcoholic or alcoholic base Composition and composition of Lysine, and subsequently subjecting the resulting mixture to conditions of Spray Drying,Thus forming a Solid Product composition comprising at least one cation Salt of a Derivative of lysine with an anion derived from a Fatty Acid omega-6 polyunsaturated the composition of the product that has a Content of SC Solvent selected from among the following: < 5% SC Weight, SC < 3% by weight, SC < 1% by weight, SC < 0.5% in weight.The compounds obtained are useful in the treatment of cancerSe refiere a un proceso para aumentar la estabilidad hacia la oxidacion de una composicion que comprende acidos grasos omega-6 poliinsaturados que comprende las siguientes etapas: (i) proporcionar una composicion de partida que comprende al menos un componente acido graso omega-6 poliinsaturado (ii) proporcionar una composicion de lisina (iii) mezclar soluciones acuosas, acuoso-alcoholicas o alcoholicas de composicion de partida y composicion de lisina, y someter posteriormente la mezcla resultante a condiciones de secado por pulverizacion, formando asi una composicion de producto solido que comprende al menos una sal de un cation derivado de lisina con un anion derivado a partir de un acido graso omega-6 poliinsaturado la composicion del producto que presenta un contenido de disolvente SC seleccionado entre los siguientes: SC <5% en peso, SC <3% en peso, SC <1 %en peso, SC <0.5% en peso. Dichos compuestos obtenibles son utiles en el tratamiento de cancer
