Abstract

1276598 Making capsules FUJI PHOTO FILM CO Ltd 3 Aug 1970 [8 Aug 1969] 37435/70 Heading B5A Capsules comprising a core material encapsulated in a waxy material are produced by dispersing the waxy material containing a core material in an upper portion A of an aqueous medium which is maintained at a temperature higher than the melting point of the waxy material to form droplets of the waxy material containing the core material, and transferring the droplets to a lower portion B of the medium maintained at a lower temperature than said melting point. A dispersion of core material S in a liquefied waxy material T may be added dropwise to the medium, or such dispersion may be cooled, crushed to a solid powder and then fed to the medium. The waxy material is defined as a water-insoluble organic material which is solid at 20‹ C. and is softened or liquefied at temperatures between 20‹ C. and the boiling point of the aqueous medium; examples are Japanese tallow, cotton wax, beeswax, whale wax, hydrous lanolin, polyethylene and paraffin. Examples given of aqueous mediums include an aqueous medium of an inorganic or organic salt, gum arabic, gelatin, polyvinyl alcohol or cellulose.
