  • Publication number: 20160021916
    Abstract: The palatability of a non-starch water-soluble polysaccharide (A) can be improved by at least partially coating the non-starch water-soluble polysaccharide (A) with a methylcellulose (B) having anhydroglucose units joined by 1-4 linkages wherein hydroxy groups of anhydroglucose units are substituted with methyl groups such that s23/s26 is 0.36 or less, wherein s23 is the molar fraction of anhydroglucose units wherein only the two hydroxy groups in the 2- and 3-positions of the anhydroglucose unit are substituted with methyl groups and wherein s26 is the molar fraction of anhydroglucose units wherein only the two hydroxy groups in the 2- and 6-positions of the anhydroglucose unit are substituted with methyl groups, with the proviso that the non-starch water-soluble polysaccharide (A) is different from said methylcellulose (B).

  • Publication number: 20140370090
    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.

  • Patent number: 5339769
    Abstract: A process for producing a granular absorbent material by distributing a liquid mixture of a clumping agent substantially uniformly over an inert solid substrate is disclosed. In an alternative process, a free-flowing absorbent material is produced by the process of distributing a liquid mixture of a clumping agent over a blend of a porous inert solid substrate and a water-swellable clumping agent. An absorbent material produced by the process of the present invention is free-flowing and agglomerates upon contact with a liquid.
