  • Patent number: 6902609
    Abstract: The present invention is directed to film coating systems for use on oral dosage forms such as compressed tablets and orally-ingestible substrates which have improved pearlescent qualities. The film coating systems can be applied either directly to a substrate or after the substrate has been coated with a subcoat. In preferred aspects, the pearlescent film coating is prepared as a dry powder mixture containing a cellulosic polymer, a detackifier, a gloss enhancer, and a pearlescent pigment. Film coating compositions containing an aqueous suspension of the powder mixtures, methods of applying the coatings to substrates and the coated substrates are also disclosed.
    Type: Grant
    Filed: February 13, 2004
    Date of Patent: June 7, 2005
    Assignee: BPSI Holdings, Inc.

  • Patent number: 5470581
    Abstract: A method of coating substrates such as pharmaceutical tablets, food and confectionery forms, agricultural seeds and the like, with a protective film comprises the steps of mixing a cellulosic polymer, maltodextrin, and a plasticizer into water to form an aqueous coating suspension, spraying an effective amount of said coating suspension onto said substrates to form a film coating on said substrates, and drying the film coating on said substrates. Optionally, a detackifier, a secondary film former, a flow aid, and/or a colorant may be dispersed into the coating suspension before applying the coating suspension to the substrates. A dry powder edible film coating composition for use in pharmaceuticals, food and confectionery forms, agricultural seeds, and the like, comprises a dry mixture of a cellulosic polymer, maltodextrin, and a plasticizer. Optionally, the dry coating composition may include a detackifier, a secondary film former, a flow aid, and/or a colorant.
