Abstract: The invention relates to methods for producing a formulation releasing active substance in a controlled manner. Said methods are characterized in that a solvent-in-water Pickering emulsion is applied to a solid carrier. Also disclosed are formulations which release active substance in a controlled manner and are produced according to the inventive method.

Abstract: The process for producing multilayered sheetlike structures, particles or fibers comprises the steps of (a) applying a reactive polycarboxylic acid or one of its derivatives atop a sheetlike, particulate or fibrous carrier material already comprising, or previously provided with, groups reactive toward, capable of covalent bonding with, the polycarboxylic acid or one of its derivatives, (b) if appropriate heating the carrier material treated in step (a) to a temperature in the range from 60° C. to 130° C. and preferably to a temperature in the range from 80° C. to 120° C. to hasten, complete or further optimize the covalent bonds, (c) applying atop the carrier material a cellulose capable of covalent bonding with the polycarboxylic acid or its derivatives. The present invention further relates to the use of the present invention's process for production of multilayered sheetlike structures, particles or fibers for hydrophilicizing surfaces, in particular for adhesion promotion between hydrophobic and hydrophilic materials and for improving the washability of synthetic fibers, the surfaces which are hydrophilicized by the process forming the sheetlike, particulate or fibrous carrier material.
