Solid perfumed preparation in the form of microbeads and the use thereof
First Claim
1. A solid fragranced preparation with increased persistence in the form of round microbeads obtained from forcing a molten mass through a nozzle, wherein the microbeads consist essentially of:
- 10 to 40% by weight of a volatile aromatic raw material or a mixture of volatile aromatic raw materials,60 to 90% by weight of meltable excipients comprising one or more meltable alkylmethyl siloxanes and none or at least one meltable excipient selected from the group consisting of fatty alcohols, fatty acids, glycerol esters, hydrogenated oils, fatty acid salts, waxes selected from the group consisting of microcrystalline waxes, white wax, carnauba wax and paraffin, polyethylene glycols of high molecular weight, plant fats, and fatty acid esters, andnone or at least one member of the group consisting of polymers that are soluble or dispersible in the molten mass, mineral additives, surfactants, antioxidants, colorants, and any combination thereof, wherein polymers soluble or dispersible in the molten mass are selected from the group consisting of cellulose derivatives, acrylic resins, polyvinyl acetates, allyl methacrylate cross polymers, polyalkylene resins, polylactic resins, maleic anhydride resins, silicone resins, and any combination thereof, andwherein the microbeads have a melting point between 25°

Abstract
The invention concerns a solid perfumed preparation with high persistency in the form of microbeads and comprising a volatile aromatic raw material, or a mixture of volatile aromatic raw materials, and one or several fusible excipients. Said preparation can further comprise one of the following constituents: one or more polymers dispersible in the melted mass formed by the constituents of the preparation, one or more mineral additives, one or more surfactants, one or more antioxidants, one or more colouring agents. The invention can be used in cosmetics and in household product industries.
