  • Patent number: 8679629
    Abstract: A microcapsule comprising a core containing a hydrophobic liquid or wax within a polymeric shell, in which solid particles insoluble in the hydrophobic liquid or wax are distributed throughout the core, wherein an oil soluble dispersant polymer is adhered to the surface of the solid insoluble particles. Processes of obtaining the microcapsules and dispersions of microcapsules in a liquid are claimed. The microcapsules can be used in a variety of applications particularly in the field of thermal energy storage. Suitably the microcapsules can be designed to have a particular density and can be used in the transfer fluids where the density of the microcapsules are the same as the carrier fluid.

  • Patent number: 6329057
    Abstract: Polymer particles comprising a hydrophobic organic matrix and located at the exterior free cationic groups and a further polymer which comprises free hydroxy groups. The particles are produced by an aqueous suspension polymerization process wherein the continuous aqueous phase contains a polymerization stabilizer and a dissolved vinyl addition cationic monomer. The polymerization stabilizer can be any suitable polymer that comprises free hydroxy groups. The process results in polymers of average particle size in the range 50 to 150 microns and reduced levels of undesired polymer emulsion or undersized particles. The particles are particularly useful for absorbing water insoluble active ingredients, such as insecticides, insect repellents, fragrances, pheromones for subsequent slow release. The cationic surface character of said polymer particles makes them especially useful for forming stable dispersions or slurries in active concentrates such as perfume bases or detergent concentrates.

  • Patent number: 6024943
    Abstract: Perfume is absorbed within organic polymer particles which have a further polymer at their exterior. The further polymer incorporates free hydroxyl groups and serves to promote deposition of the particles from a wash or rinse liquor. The further polymer may be part of an encapsulating shell, but more conveniently is used as a stabiliser during polymerisation of the particles. Highly hydrolysed polyvinyl alcohol is preferred.
