Brief description of the formulation of active substances in the agrochemical reguler kinetic of release, the protect the outer ends, and their users to secure

摘要

The present invention relates to a novel method for formulating an active principle, any ingredient in order to protect the user, to protect the active substances of the external attack, and to control its kinetics of release. It is based on the use of emulsions acrylic thickening and at a ph greater than 5 and containing hydrophobic groups, in order to trap the active substance. The present invention also relates to the various embodiments of the active principle thus formulated: a mixture in the water of this active principle with these emulsions, a dispersion of solid particles of these polymers and of the active ingredient after acidification, and the solid particles obtained in the dry state, after elimination of water. Finally, the invention relates to the use of these different formulations in order to protect an active principle, to protect the user and to slow down the kinetics of release.
