摘要：
A composition suitable as coating or binding agent for pharmaceutically, nutraceutically or cosmetically active ingredients includes:
a) at least one (meth)acrylate copolymer a), including polymerized units of 5-25% by weight of methacrylic acid and 75-95% by weight of C1-4-alkylesters of methacrylic acid and/or C1-4-alkylesters of acrylic acid, and
b) 1-25% by weight, based on the total weight of at least one (meth)acrylate copolymer a), of an alkali or ammonium salt of a saturated aliphatic monocarboxylic acid having 10 to 30 carbon atoms,
and c) or d) or both c) and d)
c) 2-25% by weight, based on the total weight of a), of at least one compound selected from glyceryl tristearate, hydroxypropyl methylcellulose, glyceryl behenate, and glyceryl monostearate and/or
d) 25-90% by weight, based on the total weight of a), of at least one selected from talc, rice hulls in powder form, magnesium stearate, corn starch, and microcrystalline cellulose.
