MT 180 Dispersion stability of suspo-emulsion w CIPAC 39 th meeting, May 1995 in Limassol A CIPAC collaborative study will be started in October 1995. w CIPAC 40 th meeting, May 1996 in Beijing A CIPAC study with a method for the determination of dispersion stability of suspo -emulsions (SE). suspension concentrates (SC), water dispersible granules (WG), wettable powders (WP), and emulsifiable concentrates (EC) is on the way. Samples will be sent to 35 participants in May. w CIPAC 41 st meeting, June 1997 in Roskilde CIPAC/3979, trial with a method for the determination of dispersion stability of suspo-emulsions (SE). SC, WG, WP, EW and EC formulations had also been tested in this study because it seemed to be necessary to have the gap filled between MT 173 (low concentrations) and MT 36 (high concentrations). 29 laboratories participated.

MT 180 Dispersion stability of suspo-emulsion w CIPAC 41 st meeting, June 1997 in Roskilde (cont’d) Decision The method for the determination of the dispersion stability of suspoemulsions (SE), CIPAC/3978, has been adopted as provisional CIPAC method. A footnote will be added to the method to indicate that this method may be used as screening method for other water dispersible formulations. w CIPAC 42 nd meeting, July 1998 in York Decision The provisional method for the determination of the dispersion stability of water dispersible formulations, CIPAC/3978, has been accepted as full CIPAC method.

MT 180 Dispersion stability of suspo-emulsion w Why is DAPF of the opinion that for OD- and DC-formulations further testing in a collaborative trial will not be necessary? CIPAC MT 180 was developed to characterise spray mixtures which are formed when suspo-emulsions are diluted with water in terms of dispersion stability. In particular, the parameters creaming and sedimentation in the spray mix are determined. Taking the phys. /chem. properties of such heterogeneous systems into account, it can be concluded that other formulation types forming a dispersion in form of solid particles and fine globules in the continuous water phase of the spray dilution, can be characterised using the same method.
