Abstract:
An aqueous enteric coating composition comprising: a dispersion of about 5 to 45 weight percent of a hydrophobic compound having from about 12 to 20 carbon atoms selected from the group consisting of alcohols, fatty acids and salts thereof, fatty amides and salts thereof, and lipids and about 5 to 50 weight percent of a water-insoluble flake material, dispersed in an aqueous solution of about 35 to 70 weight percent of a water-soluble salt of an enteric polymer selected from the group consisting of cellulose acetate phthalate (C-A-P), cellulose acetate trimellitate (C-A-T), hydroxypropyl methylcellulose phthalate (HPMCP), methacrylic acid/ethyl acrylate copolymer, hydroxypropyl methylcellulose acetate succinate (HPMCAS), and polyvinyl acetate phthalate (PVAP), wherein said weight percentages are based on a total solids weight.
