Suggested is a rim block with improved scent performance, comprising or consisting of: (a) a solid rim block base, (b) at least one non-encapsulated perfume oil, and (c) at least one perfume oil same or different from component (b) encapsulated in a maltodextrin matrix.

Rim block with improved scent performance

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. In addition, the present invention relates to the use of the multilayer microcapsules and suspensions of the multilayer microcapsules as an ingredient in detergents, fabric softeners, cleaning products, scent boosters in liquid or solid form, cosmetics, personal care products, agricultural products or pharmaceutical products.

Microcapsules

The present invention relates to a process for the preparation of microcapsules, in particular isocyanate-based microcapsules with improved stability to carboxylic acid and aldehyde-containing active ingredients as core material. In addition, the present invention relates to microcapsules obtainable by the process according to the invention. In addition, the present invention relates to microcapsules, suspensions of such microcapsules, and the use of the microcapsules and suspensions as a component in detergents, fabric softeners, cleaning products, scent boosters (fragrance enhancers) in liquid or solid form, cosmetics, personal care products, agricultural products, or pharmaceutical products.

Process for the preparation of microcapsules

The invention relates to a method for producing microcapsules, comprising the following steps: (a) providing a first aqueous preparation containing at least one prepolymer; (b) providing a second non-aqueous preparation containing the active substance to be encapsulated; (c) mixing the aqueous and the non-aqueous phases in the presence of at least one emulsifier and/or stabilizer in order to form an emulsion; (d) polymerizing the at least one prepolymer contained in the emulsion from step (c) in order to obtain a dispersion of microcapsules that enclose the active substance; (e) hardening and cross-linking the microcapsules obtained in step (d); and optionally (f) removing the microcapsules from the dispersion and drying the microcapsules, the method being characterized in that the emulsion is formed in the presence of at least one 1,2-diol in step (c).

Method for producing microcapsules

The present invention belongs to the area of detergents and refers to a dispersion comprising encapsulated fragrances and the method as well as the use of the said dispersion in a process to adhere said encapsulated fragrances onto particles, powder or granules of detergent compositions.
