Abstract

La presente invención describe suspoemulsiones que comprenden micelas reversas de diámetro nanométrico y al menos 2 ingredientes activos, siendo un ingrediente activo inmiscible en agua y el otro insoluble en agua. Además, la presente invención proporciona composiciones de suspoemulsión estables, incluso en ausencia de disolventes orgánicos. La invención es particularmente útil para el control de plagas, vegetaciones indeseadas y/o malezas, a partir de la combinación de diferentes activos con diferentes propiedades fisicoquímicas. Reivindicación 1: Suspoemulsión caracterizada porque comprende: a) del 50% al 95% en masa de una fase continua, inmiscible en agua, que comprende: i) al menos un ingrediente activo inmiscible en agua, y ii) al menos un emulsionante de agua en aceite con HLB en el intervalo de 3 a 9; b) del 5% al 50% en masa de una fase acuosa discontinua que comprende: i) partículas sólidas dispersas de al menos un ingrediente activo insoluble en agua, en el cual dicha fase discontinua está formada por micelas reversas, cuyo diámetro de al menos el 90% de dichas micelas reversas está en el intervalo entre 0,1 mm y 50 mm. Reivindicación 16: Proceso para preparar una suspoemulsión, como se define en cualquiera de las reivindicaciones anteriores, caracterizado porque comprende los pasos: a) Preparar una emulsión de agua en aceite que comprenda: i) Mezclar del 50% al 95% en masa de al menos un ingrediente activo inmiscible en agua con 5% a 40% en masa de al menos un emulsionante de agua en aceite con HLB en el intervalo de 3 a 9; ii) Agregar en un mezclador de alto cizallamiento del 50% al 70% en masa de la mezcla obtenida en i) y del 35% al 50% en masa de agua, y mezclar hasta obtener una emulsión de agua en aceite en la cual el 90% de dichas micelas reversas están en el intervalo entre 0,1 mm y 40 mm; b) Preparar una suspensión acuosa que comprende del 50% al 80% en masa de partículas sólidas dispersas de un ingrediente activo insoluble en agua; c) Mezclar del 50% al 95% en masa de la emulsión obtenida en a) con 5% al 50% en masa de la suspensión obtenida en b).The present invention describes suspoemulsions comprising nanometer diameter reverse micelles and at least 2 active ingredients, one active ingredient being immiscible in water and the other insoluble in water. Furthermore, the present invention provides stable suspoemulsion compositions, even in the absence of organic solvents. The invention is particularly useful for the control of pests, unwanted vegetation and/or weeds, from the combination of different active ingredients with different physicochemical properties. Claim 1: Suspoemulsion characterized in that it comprises: a) from 50% to 95% by mass of a continuous phase, immiscible in water, comprising: i) at least one active ingredient immiscible in water, and ii) at least one water emulsifier in oil with HLB in the range of 3 to 9; b) from 5% to 50% by mass of a discontinuous aqueous phase comprising: i) dispersed solid particles of at least one water-insoluble active ingredient, in which said discontinuous phase is formed by reverse micelles, whose diameter is at least 90% of said reversed micelles are in the range between 0.1 mm and 50 mm. Claim 16: Process for preparing a suspoemulsion, as defined in any of the preceding claims, characterized in that it comprises the steps: a) Prepare a water-in-oil emulsion comprising: i) Mix from 50% to 95% by mass of al least one water-immiscible active ingredient with 5% to 40% by mass of at least one water-in-oil emulsifier with HLB in the range of 3 to 9; ii) Add in a high shear mixer from 50% to 70% by mass of the mixture obtained in i) and from 35% to 50% by mass of water, and mix until obtaining a water-in-oil emulsion in which the 90% of said reverse micelles are in the range between 0.1 mm and 40 mm; b) Prepare an aqueous suspension comprising 50% to 80% by mass of dispersed solid particles of a water-insoluble active ingredient; c) Mix 50% to 95% by mass of the emulsion obtained in a) with 5% to 50% by mass of the suspension obtained in b).
