  • Patent number: 9809684
    Abstract: The present invention relates to aqueous resin emulsions containing at least a non-ionic surfactant of general formula R1-(A1O)n-(A2O)x-(A3O)y—R2, obtained by the phase inversion emulsification process. In particular, the invention relates to aqueous resin emulsions commonly used in solvent-based paints, such as, for example, alkyd resins. Said emulsions are stabilized by non-ionic and anionic surfactant compositions which promote the inversion of the water-oil to oil-water phases in the presence of low water content, enabling water-oil type emulsions to be obtained with high productivity and high solids content, even in low shear conditions.

  • Publication number: 20160088835
    Abstract: Novel agrochemical oil dispersion formulations include at least one active ingredient suspended in oil phase, dispersants, a clay-based rheological additive, a cellulose derived rheological additive and emulsifying agents, wherein they can further include at least one active ingredient solubilized in the oil phase. These agrochemical oil dispersion formulations can be used in spray mixtures for controlling pests in agriculture. The novel agrochemical oil dispersion formulations are obtained by a process which includes dispersing at least one active ingredient in the oil phase with dispersants and a clay-based rheological additive, followed by milling the dispersed mixture and a final mixing step where cellulose- and clay-based rheological additives are added in addition to emulsifying agents, wherein at least one active ingredient can also be added by solubilization.
