Abstract:
The present invention relates to an aqueous pour point depressant dispersion composition comprising a thermoplastic polymer, preferably ethylene vinyl acetate (EVA); a dispersing agent; water; optionally an aqueous freezing point depressant; and optionally a stabilizing agent wherein the volumn average particle size of the dispersed thermoplastic polymer is equal to or less than 1 micrometers and a method to make and use said composition.
Abstract:
A coating composition comprising a) a cellulose ether, and b) a water-dispersible starch which has, when measured as a 15 wt.-% dispersion in water at 25 °C, a number average particle size of from 0.01 to 2 micrometers and a viscosity of not more than 2000 mPa.s, wherein the weight ratio between the cellulose ether and the water-dispersible starch is from 1 : 2 to 20 : 1, is useful for efficiently coating dosage forms with a low moisture permeability.
