cellulose polymer and the film coating equipment and to the assembling and the film coating (Film Coatings and Film Coating Compositions Based on Cellulosic Polymers and Lactose)

摘要

A dry film coating composition for use in coating pharmaceuticals, food, confectionery forms, agricultural seeds, and the like, comprises a cellulosic polymer, and lactose. The composition may include an optional plasticizer, and an optional pigment. A method of coating substrates such as pharmaceutical tablets, food and confectionery forms, agricultural seeds, and the like comprises mixing a cellulosic polymer and lactose into water to form an aqueous coating suspension, spraying the coating suspension onto said substrates to form a film coating on said substrates, and drying the film coating on said substrates. Optionally, a plasticizer and/or pigment may be dispersed into the aqueous coating suspension. The method of making a dry film coating composition for use in coating pharmaceutical tablets, food and confectionery forms, agricultural seeds, and the like, comprises mixing a cellulosic polymer and lactose together to form a dry film coating composition. Optionally, a plasticizer and/or pigment is blended with the cellulosic polymer and lactose. A method of making a dry film coating composition for use in coating pharmaceutical tablets, food and confectionery forms, agricultural seeds, and the like comprises mixing a cellulosic polymer and lactose into water to form an aqueous coating suspension, and spray granulating the aqueous coating suspension to form a dry film coating compositions. Optionally, a plasticizer and/or pigment may be mixed into the aqueous coating suspension. An aqueous coating suspension for coating substrates such as pharmaceutical tablets, food and confectionery forms, agricultural seeds, and the like, comprises a mixture of a cellulosic polymer, lactose, water, and optionally, plasticizer and/or pigment.
