| abstract |
The invention relates to a method for producing a granulate or powder which is suitable as a coating and binding agent for oral and dermal medicaments, cosmetic products or food supplements and substantially consists of (a) a copolymer containing radically polymerized C1 to C4 esters of acrylic acid or methacrylic acid and additional (meth)acrylate monomers that comprise functional tertiary amino groups, (b) 3 to 25 percent by weight relative to (a) of an emulsifier having an HLB value of at least 14, and (c) 5 to 50 percent by weight relative to (a) of C12 to C18 monocarboxylic acid or a C12 to C18 hydroxyl compound. Components (a), (b), and (c) are simultaneously or successively blended or mixed by optionally adding a pharmaceutical agent and/or other common loading agents, melted and mixed in a heatable mixer, whereupon the melted product is cooled and comminuted into a granulate or powder. |
