Abstract

1,142,649. Microcapsules. WALLACE & TIERNAN Inc. 31 March, 1966 [31 March, 1965], No. 14279/66. Heading B8C. [Also in Division C3] The process set out in Specification 1,091,141 is modified where the capsule skin forms by growing outwards from the encapsulated liquid into the continuous phase liquid, by addition of a solid colloidal dispersion agent at least to the continuous phase liquid. This forms on the capsules a coating which reduces agglomeration. The encapsulated liquid is generally hydrophilic and the continuous phase liquid organic. Examples of dispersing agents are colloidal magnesium aluminium silicate, activated attapulgite, talc and rice powder starch.
