It may be favourable, though not necessary, to continue comminution after addition of the aqueous suspension to the emulsion until the desired particle size is achieved. Moreover, the process of the present invention does not require tedious com- minution techniques as normally required in the preparation of aqueous atlxo concentrates.

Croda makes their documentation available in the regions indicated below: When this exceeds a certain value, the dispersion or emulsion approaches thermodynamic stability.

US USB2 en CN CNB en Amorphous forms include liquids forms, i. The thus obtained suspension was filtered using a atllox sieve to remove large material.

In a particular preferred embodiment of the invention, the emulsion comprises at least one non-ionic polymeric surfactant, in particular a non-ionic polymeric surfactant of the groups c. 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.

Therefore, average particle diameters are also termed “volume median diameters”. It has been found to be advantageous for the stability of the obtained suspension that the surfactant s is are chosen from those surfactant and surfactant combinations which have been mentioned as preferred or particular preferred surfactants in connection with the surfactants contained in the aqueous aglox of the pesticide compound.

In particular, the process of the present invention does not require the preparation of large amounts of solid crystalline material of the pesticide atkox prior to formulation and thus it is less time-consuming and avoids the handling of solid crystalline material, which might be particularly problematic when the pesticide has a low melting point.

CA CAC en Furthermore, the aqueous suspensions obtained by the process according to the invention can be formulated with further pesticide compounds.

This is especially true in the light of recent advances in controlled living radical polymerisation chemistry, as exemplified by atom transfer radical polymerisation ATRP and, to a lesser extent, reversible addition fragmentation transfer RAFT polymerisation.

The compositions of the invention may optionally comprise also coloring agents such as pigments or dyes, in particular, if the composition is intended for seed treatment purposes. However, surface properties of the particles are critical to the effectiveness of the polymer.

In case of pyraclostrobin the temperature, where the emulsified droplets of pyraclostobin remain in the molten state, will be generally in the range from 45 to 90 0 C, in particular from 50 to 80 0 C.

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 further pesticide compound may also be added as a liquid, e. In another preferred embodiments of the invention, the first pesticide compound is pyraclostrobin and the further pesticide compound is selected from the group of cona- zole fungicides as mentioned above, in particular from the group consisting of meth- conazol, epoxiconazol and mixtures of epoxiconazol with fipronil.

However, this method principally requires the organic pesticide compound to be in a solid state, preferably in a crystalline state, as the organic pesticide may clog the milling apparatus.

When low melting organic pesticides are formulated as an SC one may encounter difficulties during preparation. In particular, the term “aqueous suspension concentrate”, as used herein, includes aqueous suspension concentrates for field application, which are also termed as SC formulations, as well as aqueous suspension concentrate formulations for seed treatment, which are also referred to as FS formulations.

The obtained formulation contained Suitable surfactants c25 are described e. 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 PAO moiety usually comprises at least 3, preferably at least 5, in particular 10 to repeating units number average which are derived from one or more C3-Cio alkylene oxides, such as propylene oxide, 1 ,2-butylene oxide, cis- or trans-2,3-butylene oxide or isobutylene oxide, 1 ,2-pentene oxide, 1 ,2-hexene oxide, 1 ,2-decene oxide and styrene oxide, among which C3-C4 alkylene oxides are preferred.

EP EPB1 en Ci-Cio-alkylesters of C3-C5 monoethylenically un- saturated carboxylic acid monomers, in particular Ci-Cio-alkylesters of acrylic acid or methacrylic acid Ci-Cio-alkylacrylates and C1-Calkylmethacrylat. Dispersions formed using Atlox are sterically stabilised by the hydrated PEG extending from the acrylate polymer backbone and are relatively insensitive to the presence of salts or solubilised organic materials in the aqueous phase.

The terms polyethyleneglycol, polyethoxylates and polyethoxylated refer to polyether radicals derived from ethyleneoxide.

According to the White House, U. In addition to the pesticide compound the emulsion comprises an aqueous phase which is the dispersion medium for the pesticide compound droplets. In a preferred embodiment of the invention, the pesticide compound contained in the aqueous emulsion is pyraclostrobin and the pesticide contained in the aqueous suspension which is added to the emulsion is a crystalline polymorph of pyraclostrobin, in particular a crystalline form which is essentially, i.

We’re sorry, but the industry you have selected is not currently available in your chosen language. Particle size of the aqueous emulsions and suspensions were determined on appropriate dilutions by laser light scattering using a Malvern Mastersizer Clariant, a world leader in specialty chemicals, and Eastman Chemical Company, a global advanced materials and specialty additives company, recently announced a Preferred C3-C5 monoethylenically unsaturated carboxylic acid monomers include acrylic acid, methacrylic acid and maleic acid.
