Aqueous carbonated medium containing an amino(meth)acrylate polymer or copolymer

摘要

The invention relates to an aqueous medium containing an amino(meth)acrylate polymer or copolymer which is not soluble in dematerialised water, characterized in that the medium has a content of an aqueous phase of at least 60% by weight and a content of up to 40% by weight of solids comprising the amino(meth)acrylate polymer or copolymer, whereby the aqueous phase is charged by a sufficient amount of carbon dioxide that effects the amino(meth)acrylate polymer or copolymer to be present in solute form in the medium. The aqueous medium may be used beneficially as a coating or binding solution for the spray coating or binding of pharmaceutical compositions or nutraceutical compositions or cosmetical compositions.

主权项

1. An aqueous medium, comprising:
an amino(meth)acrylate polymer or copolymer which is not soluble in demineralised water, comprising polymerized units of 20-30% by weight of methyl methacrylate, 20-30% by weight of butyl methacrylate, and 60-40% by weight of dimethylaminoethyl methacrylate, wherein the medium has a content of an aqueous phase of at least 60% by weight and a content of 10 to 22% by weight of the amino(meth)acrylate polymer or copolymer, and wherein the aqueous phase is charged by a sufficient amount of carbon dioxide that effects the amino(meth)acrylate polymer or copolymer present in solute form in the medium.
