Abstract: A PROCESS IS PROVIDED FOR PREPARATION OF MINUTE CAPSULES WHEREIN PARTICLES OF INTENDED INTERNAL PHASE MATERIAL WHICH HAVE BEEN DISPERSED INDIVIDUALLY IN A LIQUID MANUFACTURING VEHICLE ARE COATED BY A SOLID POLYMERIC FILMFORMING MATERIAL. POLYMERIC MATERIAL IS PRECIPITATED FROM SOLUTION IN THE MANUFACTURING VEHICLE OR FROM SOLUTION IN THE INTENDED INTERNAL PHASE MATERIAL DUE TO A "ZONE OF INSOLUBILITY" ESTABLISHED AT THE INTERFACE BETWEEN THE PARTICLES AND THE MANUFACTURING VEHICLE. THE PARTICLES ARE EITHER LIQUID DROPLETS OR SOLID PARTICLES HAVING AN ASSOCIATED LIQUID THEREWITH. THE NOVEL PROCESS IS UTILIZED TO ENCAPSULATE PARTICLES WHICH ARE, TO SOME DEGREE, MISCIBLE WITH THE MANUFACTURING VEHICLE.

Abstract: D R A W I N G
OPACIFIERS COMPRISING AIR-CONTAINING MICROCAPSULES HAVING AN AVERAGE PARTICLE DIAMETER OF BELOW ABOUT ONE MICRON PROVIDE HIGHLY OPAQUE SURFACES WHEN COATED ONTO AND/OR INCORPORATED INTO FIBROUS AND NON-FIBROUS SUBSTRATES. THE OPACIFIERS ARE PRODUCED BY HEATING LIQUIDCONTAINING PRECURSOR MICROCAPSULES AT TEMPERATURES SUFFICIENT TO EXPEL THE LIQUID AND PROVIDE AIR IN THE MICROCAPSULE.

Abstract: To provide hollow silica particles having a dense silica shell layer.
A method for producing hollow silica particles, which comprises: adjusting the pH of an oil-in-water emulsion containing an aqueous phase, an oil phase and a surfactant to at most 3.0 and adding a first silica material to the oil-in-water emulsion, adding a second silica material to the emulsion having the first silica material added, at its pH of at least 8, in the presence of alkali metal ions, to obtain a hollow silica precursor dispersion, and obtaining a hollow silica precursor from the hollow silica precursor dispersion and obtaining hollow silica particles from the hollow silica precursor.

Abstract: Disclosed herein are a method for producing a miniaturized liposome on a large production scale, and an apparatus for producing a liposome which is to be used in the above-mentioned method. Provided is a method for producing a liposome, including a step of stirring a mixture containing an oil phase in which at least one lipid is dissolved in an organic solvent and a water phase in a first tank of an apparatus having the first tank and a circulation path, in which the ratio of the capacity of the circulation path to the total capacity of the tank and the circulation path is 0.4 or less and/or the time required for the mixture to return to the first tank after being discharged therefrom is within 2.0 minutes.
