Abstract: A process for producing micronized dispersed micro-particles and to micro-particles produced by this process. In the process a combination of a dispersion liquid, an active ingredient and a wax is passed at a temperature at which the wax is molten into a high energy micro-particle producing machine operating at a temperature at which the active ingredient and wax are kept molten and producing a composition comprising a plurality of micro-particles dispersed in said dispersion liquid by cooling said combination to a temperature below the solidification temperature of each of said micro-particles before each said micro-particle leaves said micro-particle producing assembly.

Abstract: Air treatment apparatus comprises an electric heating element (5) and a refill pack containing wax or paraffin granules (2) incorporating a fragrance or other active substance eg. insect repellent. In another embodiment heat is supplied by a exothermic reaction mixture.

Abstract: The invention relates to a method for attaching a volatizable active substance (4) to a supporting material (1) and for the controlled release of this active substance (4) into the surrounding area, during which the volatizable active substance (4) is introduced into a carrier material (2), which is solid at normal temperature and which is melted by heating, and a carrier material/active material melt S is placed in contact at least with a portion of the supporting material (1) having the normal temperature or a lower temperature whereby attaching thereto in the form of a film F, and the volatizable active substance (4) is released in a controlled manner by natural and/or artificial influence of air and/or heat from the carrier material (2) attached in the form of a film F.

Abstract: An agent for use in dishwashers, which enables the dishwasher to be fragranced during protracted operating intervals and simultaneously improves the pearl-off performance of the rinsing water during the drying cycle, and which has a solid, preferably granular, structure at normal temperatures. The agent can be produced by exclusive use of a solid fragrance known per se. The solid fragrance contains a carrier material which is made of fatty alcohol or a mixture containing fatty alcohol and which is solid at normal temperatures, and, dissolved therein, a fragrance which is liquid at normal temperatures. The solution is composed quantitatively of between 40 and 60% by weight of carrier material and between 60 and 40% by weight of fragrance.

Abstract: The invention relates to a method for the production of a solid fragrance concentrate, by absorption of a liquid fragrance or fragrance mixture in a solid or solid mixture, using one or several surfactants and/or co-surfactants, solid at normal temperatures as solid or solid mixture, whereby the liquid fragrance or fragrance mixture is dissolved in the above at a temperature above the solidification temperature of the solid or solid mixture and the solution subsequently solidified by cooling. The solid or solid mixture comprises fatty alcohol(s) or a mixture of fatty alcohol(s) and fatty acid(s) and/or fatty alcohol ethoxylate and/or polyethylene glycol.

Abstract: The invention relates to a method for producing a solid odorous substance from at least one odorous substance that is liquid at normal temperature and at least one carrier material (6) that is solid at normal temperature. According to the method, the at least one fine-particle carrier material (6) is exposed to a spray mist (7) of at least one liquid odorous substance in a fluidised bed.
