Abstract:
The present invention relates to a method for producing beads comprising a material capable of gelation, said method comprising the steps of: (i) combining (a) a liquid composition comprising a material capable of gelation; and (b) a first hydrophobic phase; (ii) subjecting the liquid composition and the first hydrophobic phase, to means for emulsification in a first reactor by addition of external mechanical energy creating an emulsion comprising individual droplets comprising the material capable of gelation in the first hydrophobic phase (wherein the material capable of gelation provides a discontinuous phase and the first hydrophobic phase provides a continuous phase); (iii) stabilising the droplets by transferring the emulsion from the first reactor to a stabilisation reactor wherein the emulsion obtained in step (ii) is subjected to means for gelation in order to obtain gelation within 5 minutes or less, and the beads are formed.
Abstract:
The invention relates to a process for preparing microspheres comprising an ionically crosslinked polymer, the process comprising: (a) producing liquid aerosol droplets (13) from a solution (3) comprising an ionically crosslinkable polyionic polymer into a continuous gas stream by using an ultrasonic nebulizer; (b) transferring the gas stream into a gelling solution (10) comprising di-, multi- or polyvalent ions, whereby crosslinked polymer microspheres (14) are formed, (c) separating the microspheres from the gelling solution, and (d) optionally, filtering the microspheres through a screen.
Abstract:
A process for producing inorganic spheres, which comprises injecting an aqueous liquid containing an inorganic compound into a laminar flow of an organic liquid which runs at a flow rate of from 0.001 to 2 m/s in a flow path compartmentalized by a partition wall through a plurality of inlet holes formed in one partition wall to form a W/O type emulsion containing the organic liquid as a dispersion medium and the aqueous liquid containing the inorganic compound as a dispersed phase, and solidifying the aqueous liquid containing an inorganic compound in the W/O type emulsion, wherein the partition wall having a plurality of inlet holes is made of a metal sheet having a surface subjected to water repellent treatment.
Abstract:
Porous spheroidal silica having a particle size in the range 1 to 400 microns, axial ratios of 1:1 to 1:12 has up to 50% by weight of the SiO₂ of included material, such as for example perfumes, flavouring materials, pigments, germicides, bactericides, fungicides, bleaching agents, skin benefit agents, therapeutic agents, dispersed in the silica as particles or droplets in the size range 0.01 to 10µm. The spheroids can be made by mixing together an aqueous, stabilised silica sol containing dispersed therein up to 50% by weight of the silica of an included material and an aqueous solution of a non-adsorbing polymer to form a phase separated system comprising silica droplets containing included material in a polymer-rich continuous phase and condensing the silica sol to aggregate the droplets to form silica spheroids containing the dispersed included material. The included material can be released in use by eg. wetting, attrition, dissolution, pH change, heating.
