Abstract: The present invention relates to a composition and a method for producing a composition. The composition comprises a saponified solution of water and lye of sodium hydroxide or potassium hydroxide, and tall oil, wherein the composition comprises particles having a size of between 5 nm and 100 nm, as determined by a dynamic laser light diffraction scattering method using Malvern Zetasizer Nano-ZS. The method comprising: providing a preheated basic solution of water and lye of either sodium hydroxide or potassium hydroxide; and saponification by adding tall oil to the heated basic solution during mixing, to form a saponified solution.

Abstract: Described is a saponified tall oil that can be used as an insecticide. Also described is an insecticide that contains a saponified tall oil. Also described is to a method for producing a composition or an insecticide containing the saponified tall oil. The method includes: providing a heated basic solution of water and lye; and performing saponification by adding tall oil to the heated basic solution during mixing, to form a saponified solution.
