Abstract: The present invention relates to a process for the production of multilayer microcapsules, in particular multilayer odiferous substance capsules or fragrance compound capsules, which have improved stability and odiferous substance release or fragrance compound release compared to prior art capsules. In addition, the present invention relates to multilayer microcapsules comprising at least one hydrophobic odiferous substance or fragrance compound obtainable by the process of the invention. In another aspect, the invention described herein relates to multilayer microcapsules comprising a core comprising at least one hydrophobic odiferous substance or fragrance compound, and a capsule shell.

Abstract: The present invention relates to the field of liquid solubilising systems. More specifically, the present invention relates to a macroemulsion comprising a hydrophobic active substance, which enhances the transfer of said hydrophobic active substance to a subject or object. A method for producing the macroemulsion, and the use of said macroemulsion to provide a sensory effect or other benefits, are likewise provided. The present invention also pertains to the use of the macroemulsion for preparing consumer products.

Abstract: A two-phase system containing at least one solvatochromic dye, water, at least one fragrance, and at least one solvent. Wherein the two-phase system includes liquid phases layered one on top of the other. The inventive compositions can be used as exhaustion indicators for fragrance release systems.

Abstract: The invention relates to stabilization systems for capsules in washing and cleaning compositions, wherein the capsules contain active ingredients or other ingredients and have an average particle size distribution from 0.1 nm to 1000 ?m.
