AU Date of ref document: Polymeric surfactants fall into several categories but two most common architectures are block copolymers and random copolymers. EP-A discloses a process for the preparation of aqueous suspensions of pesticide compounds, where the molten pesticide compound is metered into a cool jet of an aqueous solution of formulation additives.

The force-distance curves below indicate only one minimum 49113 depth depends on several factors, importantly one of which is the adsorbed layer thickness. In the melt-emulsification process the molten organic compound is emulsified in the aqueous phase by applying high shear to the mixture which is then quenched. The amount of sample was 5 to 10 mg.

The star consists of a sorbitol base reacted with ethylene oxide EO. Subscribe to daily email alerts of AgroNews. A conventional suspension concentrate of pyraclostrobin see e.

However, surface properties of the particles are critical to the effectiveness of the polymer. The process according to any of the preceding claims, where the aqueous emul- sion additionally contains at least one anionic polymeric surfactant having polyether side chains.

Forward Favorites Print Share. Suitable further pesticides for the purpose of the invention include but are not limited to: The process according to claim 1 1where the anionic polymeric surfactant is polymer having a carbons backbone carrying carboxylate groups and polyether side chains.

In this case, the obtained mixture will be generally subjected to a further comminution step of the thus obtained mixture. In another particular preferred embodiment of the inven- tion, the emulsion comprises at least one non-ionic polymeric surfactant, in particular a atlos polymeric surfactant of the groups c.

The process according to claim 18, wherein the formulation additive is selected from anti-freeze agents, viscosity-modifying agents, antifoams, bactericides and coloring agents. The further pesticide compound may be added as a solid material, e. In a preferred embodiment of the surfactants c. Hydrophilic PEG chains extend into the water phase and the hydrophobic polymer backbone sits on the interface of the dispersed particle covering the surface and the extended polymer chains prevent the particles from coming into contact with other particles.

Functionality of a monomeric surfactant, a traditional polymeric surfactant and the newly developed star polymer Atlox Examples of such organic pesticide compounds include but are not limited to the compounds giving in the following table:. If the aqueous emulsion contains a combination of at least one anionic surfactant and at least one non-ionic surfactant, the weight ratio of anionic surfactant and non-ionic surfactant is preferably from 1: We’re sorry, but the industry you have selected is not currently available in your chosen language.

In a particular embodiment of the invention, the first pesticide compound is pyraclos- trobin and the further pesticide compound is metconazol. However, this process is limited to pesticide compounds having a melting-point significantly above 70 0 C. Preferably the further surfac- tant is selected from the groups c. Preparation of an aqueous suspension concentrate containing pyraclos- trobin and metconazol. In conclusion, polymeric surfactants offer the formulator a toolbox of materials in which greater stability of formulations can be achieved.

Furthermore, the aqueous suspensions obtained by the process according to the invention can be formulated with further pesticide compounds. B01A Ref document number: Wetting agents are surfactants which primarily lower the inter- facial tension between the liquid phase and the surface of the solid particles of the active ingredient here, the pesticide compound that are dispersed or emulsified in the aqueous phase, thereby assisting in stabilizing the particles in the aqueous phase.

Preferably, the surfactants that are contained in the suspensions are similar to those which are contained in the emulsions. For example, enhancing emulsion stability through increased steric hindrance of irreversible flocculation. Preferably, the emulsion of the pesticide compound is prepared by emulsifying the molten pesticide compound in water which may contain one or more surfactants.

Preferred polymeric surfactants of the group c.

Although not as well-defined as small-molecule surfactants, polymeric surfactants offer greater opportunities in terms of flexibility, diversity and functionality. The mobile phase is a gradient consisting of acetonitrile, methyl-t-butyl ether, water, isopropyl alcohol, methanol, and phosphoric acid.

This new molecule is a high molecular weight polymeric emulsifier and dispersant with low HLB developed to provide excellent stability when used in a variety of crop formulations. The aqueous suspension, which is added to the aqueous emulsion of the pesticide compound, may contain one or more surfactants and may further contain further formulation additives. Preferred surfactants and surfactant combinations are those, which are mentioned as preferred surfactant and surfactant combinations in connection with the aqueous emulsions.
