Abstract: The present invention is directed to a method for producing environmentally friendly microcapsules. Moreover, the present invention provides microcapsules obtained/obtainable by the method according to the invention, in particular multilayer microcapsules which are suitable for all kinds of industrial application, in particular in personal care and home care products. The microcapsules preferably comprise at least one oil as core material.

Abstract: A method for producing microcapsules with core material and shell material includes following steps: a) providing an aqueous two-phase system comprising at least one salt, which is at least partially not dissolved in this two-phase system and a core material, which is one phase of the two-phase system, and b) adding two solutions i) and ii) in the presence of at least one polymer soluble in solution i) and/or ii), wherein solution i) contains at least one salt of a cation of the salt from step a) and solution ii) contains at least one salt of an anion of the salt from step a). Microcapsules can be obtained or obtainable by the above method, and the microcapsules can be used in products and compositions.

Abstract: The application relates to a method of using cleaning agents, and fabric treatment agents containing a combination of at least two different microcapsules as well as to methods for releasing active substances from said microcapsules when using said agents.

Abstract: The invention relates to microcapsules, the capsule walls of which comprise a resin that can be obtained by reacting a) at least one compound selected from the group consisting of a1) amines and a2) aromatic or heteroaromatic compounds which are unsubstituted or substituted with one or more substituents from the group consisting of C1-C20-alkyl, OH, OR, COOH, SH, SR, NHCOR, OCOR, halogen, or an aromatic compound, where R is a C1-C10-alkyl group, with b) at least one aldehydic component that contains at least two carbons atoms per molecule, in the presence of c) at least one copolymer which contains units of 2-acrylamido-2-methylpropane sulphonic acid or salts (AMPS) thereof and/or 2-acrylamido-2-methylpropane phosphonic acid or salts (AMPP) thereof and units of one or more (meth)acrylates.

Abstract: The application relates to cosmetic agents, cleaning agents, and fabric treatment agents containing a combination of at least two different microcapsules as well as to methods for releasing active substances from said microcapsules when using said agents.

Abstract: The invention refers to microcapsules whose capsule wall comprise resin, and which results through reaction of at least one aromatic alcohol or its ether or derivative and at least one aldehyde component, which includes at least two C-atoms per molecule.
