Novel excipients can play a major role in innovation processes,but physico-chemical properties, performance and safetymust be adequately demonstrated. Characterizationrequirements for novel excipients are discussed and illustratedwith two examples, polyvinyl caprolactam polyvinyl acetatepolyethylene glycol grafted copolymer (Soluplus®) andmethyl methacrylate and diethylaminoethyl methacrylatecopolymer dispersion (Kollicoat® Smartseal 30 D).
