KollidonSR



Polyvinyl acetate + polyvinylpyrrolidone
CAS : 9003-20-7 + 9003-39-8
Manufacturer BASF

Kollidon® SR is composed of polyvinyl acetate and povidone (Kollidon 30) in a ratio of 8:2, in powder form. Because of the presence of hydrophobic vinyl acetate groups, Kollidon® SR is insoluble in water. This makes it suitable for the manufacture of membranes with controlled pH-independent release or production of matrix controlled release of active ingredient, using the technology of direct compression, wet granulation or extrusion.
