Patent number: 8354466Abstract: The invention pertains to a new method for formulating any agrochemical active ingredient so as to protect the user, protect this active ingredient from outside stresses, and control its release kinetics. It relies on the use of acrylic and thickening emulsions with a pH greater than five and containing hydrophobic groups in order to trap said active ingredient. The invention also pertains to the various embodiments of the active ingredient thereby formulated: a mixture in water of that active ingredient with these thickening emotions, a dispersion of solid particles of these polymers and this active ingredient after a certification, and the solid particles obtained in a dried state after the water has been removed. Finally, the invention pertains to the use of these various formulations in order to protect and active ingredient, protect its user, and slow its release kinetics.Type: GrantFiled: June 13, 2008Date of Patent: January 15, 2013Assignee: Coatex S.A.S.Inventors: Olivier Guerret, Jean-Marc Suau, Yves Kensicher
