    Abstract: 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.

    Abstract: The invention resides in a method for manufacturing a metallic hydroxide-based and metallic oxide-based powder, which is self-dispersing in water, characterized in that a metallic oxide powder is partially treated with a polymer in the form of an aqueous emulsion and/or solution, in such a way that the level of metallic hydroxide by dry weight within said treated powder is less than 99% of its total weight, and in that said polymer is a water-soluble homopolymer or copolymer containing at least one vinylic monomer. In one particular variant, the polymer is a water-soluble copolymer containing a vinylic monomer and a non-ionic monomer, and the metal is calcium and/or magnesium. The invention also pertains to the powders obtained, their uses in aqueous suspensions, in treating waste, as a chemical additive, or as a soil amendment.
