  • Patent number: 9976108
    Abstract: The present invention provides a perfuming composition that is free of ethanol and that is in the form of a transparent, clear microemulsion that contains a fragrance at a concentration of 0.5 to 50% by weight; a solvent at a concentration of 1 to 36% by weight; a non-ionic surfactant at a concentration of 1 to 35% by weight; an ionic surfactant at a concentration of 0 to 12% by weight, a cooling hydrotrope at a concentration of 0.01 to 12% by weight and water. Said microemulsions benefit from the presence of a cooling hydrotrope which allows lowering the amount of surfactant needed and provides a cooling effect.
    Type: Grant

  • Publication number: 20130064931
    Abstract: A delivery system that includes surfactant micelles, and a surfactant system of nonionic, cationic or zwitterionic surfactants, with the surfactant being present in an amount equal to or greater than its critical micelle concentration, 10% or more by weight, based on the total weight of the delivery system, of a hydrophilic phase formed of water and/or a water-soluble solvent, and from 0.0001 to 5% by weight, based on the total weight of the delivery system, of a compound having the structure or salts, and/or solvates thereof (“compound 1”), wherein at least a proportion of compound 1 is encapsulated within the surfactant micelles.

  • Publication number: 20130004615
    Abstract: The present invention relates to a process for the preparation of solid capsules that contain flavours therein, by spray drying of an emulsion of a flavour or fragrance, a natural extract of saponins, water and a water-soluble biopolymer having a molecular weight below 100 KDa. The invention further relates to the solid capsules obtainable by the method and to edible products containing them.
