The liquid hydrophilic core material can be anionic, cationic, or neutral but polar. The microcapsule population is formed by providing liquid hydrophilic core material; providing an oil continuous phase which is low boiling and preferably nonflammable, the oil continuous phase comprising preferably one or more organic oil materials such as esters with chain length up to about 42 carbons. A mixture is formed by dispersing the liquid hydrophilic material in the oil continuous phase.

| 20100304023 | WATER-IN-OIL CAPSULE MANUFACTURE PROCESS AND MICROCAPSULES PRODUCED BY SUCH PROCESS - A novel method of forming water in oil microcapsules is disclosed. According to the invention microcapsules are obtained by steps comprising dispersing an oil soluble amine modified polyfunctional polyvinyl monomer and an oil soluble bi- or polyfunctional vinyl monomer along with a thermal or UV free radical initiator (optionally included in one or both of the oil or water phases) and an organic acid into an internal phase oil; heating or UV exposing for a time (and temperature) sufficient to oligomerize the amine modified polyfunctional polyvinyl monomer and oil soluble bi- or polyfunctional vinyl monomer forming a pre-polymer. Thereafter the process involves adding to the oil phase oil a water phase comprising a dispersion in water of an anionic emulsifier (and optionally initiator), and adding an emulsifying agent. Emulsifying the water phase into the oil phase (W/O) is controlled through the quantity of water employed. The emulsion is then UV exposed or heated for a time (and temperature) sufficient to decompose the free radical initiators in the oil and/or water phases; thereby forming microcapsule wall material at the interface of the water and oil phases. | 12-02-2010 |
