Abstract:

The water dispersibility of water-soluble polymer particles can be improved by a method which comprises the following step: i) foaming a fluid composition comprising a compound A) having a weight average molecular weight of less than 10,000 or a water-insoluble polymer B) having a weight average molecular weight of at least 10,000; ii) contacting the produced foam with water-soluble polymer particles having a weight average molecular weight of at least 10,000; and iii) drying the particles, whereby the foam collapses during the contacting and/or drying step and the water-soluble polymer particles are encrusted with the compound having a weight average molecular weight of less than 10,000 or the water-insoluble polymer having a weight average molecular weight of at least 10,000.

US Classification:

424/489000, 424/493000

Abstract:

A process for dispersing a fluid in solid particles which comprises the steps of (a) contacting a gas with a fluid composition comprising (i) from 0.01 to 30 weight percent of a polymer and (ii) from 99.99 to 70 weight percent of a liquid diluent, based on the total weight of the polymer (i) and the liquid diluent (ii), to produce a foam, and (b) contacting the produce foam with solid particles of an average size of less than 2500 micrometers, the weight ratio between the foam and the solid particles being from 1:20 to 1:02. When the fluid composition comprises a binder, a granular material is produced which can be pressed to tablets.

US Classification:

Abstract:

Tablets and other objects are film coated by including in the tablet a film-forming polymer that is activated upon contact with an activating amount of liquid. The film-forming polymer, e.g., a cellulosic ether, is homogeneously mixed with the other ingredients of the tablet, shaped into any desirable form, loaded into a conventional coating apparatus, and sprayed or foamed with an activating amount of fluid, e.g., water, alcohol, etc., and dried. This coating process eliminates potential problems such as spray nozzle clogging, inappropriate coating fluid viscosity, and the inability to properly atomize the coating fluid. This coating process does not impart any appreciable weight or thickness gain to the tablet.
