A Thickening composition as main component that uses a synthetic Thickener Paste Paste, natural or its derivative, used conventionally in a Broad Way, which combines a Thickener Component, thereby obtaining a high viscosity, which has been Impossible To obtain a Thickener component with only a small amount of use.In addition, a method of Thickening, greatly Improving the viscosity of an aqueous solution using a small amount of Thickener composition, and an adjustment method of viscosity of an aqueous solution, which uses This method of Thickening.A First component is mixed Thickener to increase the viscosity of water Thickener and a Second component is obtained from an original Plant belonging to the genus of Corchorus, and adjusted between 15% and 60%, the ratio occupied by the second Component to the total amount of the composition in which are combined with the first Component and the second Component Thickener Thickener.Thus, the viscosity of a Solution which is dissolved in mixed aqueous composition for thick is two times or more compared with the viscosity of an aqueous solution in which only the first Component Thickener is dissolved with the same Concentration.Una composición espesante que emplea como componente espesante principal un engrudo sintético, engrudo natural o su derivado, utilizado convencionalmente de modo amplio, con el cual se combina un determinado componente espesante, permitiendo así obtener una alta viscosidad, que ha sido imposible de obtener con un solo componente espesante de una pequeña cantidad de uso. Además, ofrecer un método de espesamiento que mejora notablemente la viscosidad de una solución acuosa aprovechando una pequeña cantidad de composición espesante, y un método de ajuste de viscosidad de una solución acuosa, que utiliza este método de espesamiento. Un primer componente espesante se mezcla para aumentar la viscosidad de agua y un segundo componente espesante se obtiene de una planta original perteneciente al género de Corc
