The invention relates to nanoparticulate formulations comprising at least one active compound or compound with a special effect and at least one random radical copolymer. The copolymers are formed from monomers carrying sulfonic acid groups and additional olefinically unsaturated compounds. The formulations are dispersible as nanoparticles in an aqueous medium. The invention includes, in addition, processes for the preparation of the solid and liquid formulations, and their use.

Nanoparticulate active substance formulations

A process for parallel and automated evaluation of the blushing of multiple samples of dispersion films, comprising: providing an illuminated array of spatially separated samples of dispersion films, imaging the array of samples by means of CCD camera at different times and digitizing the images, automatically determining multiple brightness for each sample at different times from the different digitized images for at least a portion of the samples, determining values of a parameter characteristic of the kinetics of the blushing from the different brightnesses, and comparing the values of the characteristic parameter for individual samples.
