摘要:
The present invention relates to a dispersion containing an aqueous continuous phase and a dispersed phase, wherein the dispersed phase exhibits a nano-sized self-assembled structurization and wherein the dispersed phase contains a pesticide with a water solubility at 25° C. of up to 10 g/l and a melting point of below 100° C. The present invention further relates to a method for preparing said dispersion comprising a step of contacting the components, and to a method for controlling phytopathogenic fungi and/or undesired plant growth and/or undesired attack by insects or mites and/or for regulating the growth of plants, where said dispersion is allowed to act on the particular pests, their habitat or the plants to be protected from the particular pest, the soil and/or on undesired plants and/or the useful plants and/or their habitat.

摘要:
The invention relates to a method of producing powdered preparations comprising diethylamino hydroxybenzoly hexyl benzoate of formula I the method comprising: a) dispersing the benzoyl benzoate of formula I in an aqueous molecularly disperse or colloidally disperse solution of a protective colloid and b) converting the dispersion obtained into a dry powder by removing the water and and drying, wherein the protective colloid used in process step a) is modified starch.
摘要:
Described is a process for preparing polymer-enrobed pigment particles, which comprises mixing in the presence of finely dispersed pigment particles a solution of a polymer in a first solvent with a second solvent in which the polymer is substantially insoluble. The pigment particle can be specifically modified by judicious selection of the polymer.

The dyes have an average particle size within the range from 5 nm to 1 &mgr;m and a variance of less than 50%. They are especially useful for ink-jet ink preparations.
摘要:
Carotenoid preparations in the form of coldwater-dispersible powders are produced bya) preparing a molecular-disperse solution of a carotenoid, with or without an emulsifier and/or an edible oil, in a volatile, water-miscible, organic solvent at elevated temperature and adding therein an aqueous solution of a protective colloid, whereupon the hydrophilic solvent component is transferred into the aqueous phase, and the hydrophobic phase of the carotenoid results as nanodisperse phase,b) heating the resulting hydrosol at from 40.degree. C. to 90.degree. C., with or without cooling of the hydrosol to from 0.degree. C. to 30.degree. C. beforehand, andc) removing the solvent and the water from the heated hydrosol, and converting it into a water-dispersible dry powder.
摘要:
In a fiber-optical sensor used for measuring the Doppler broadening of scattered laser light by the principle of quasi-elastic light scattering (QELS), the scattered light originating from particles in movement, the emergence surface (7) for the laser light at the end of a single-mode or multimode light guide (3) used as an immersion probe is inclined at an angle 0
