ISP has self-affirmed that its Plasdone K-29/32 and Plasdone K-90 binders, as well as Polyplasdone XL and XL-10 disintegrants are Generally Recognized as Safe (GRAS), following a comprehensive evaluation of research and toxicology studies by a qualified, independent scientific panel. The GRAS status allows for the inclusion in nutritional and supplement products.
Plasdone K-29/32 and Plasdone K-90 binders are linear homopolymers of N-vinyl-2-pyrrolidone. Among other uses, the polymers serve as wet granulation binders. Polyplasdone XL and XL-10 disintegrants are insoluble, crosslinked, homopolymers of N-vinyl-2-pyrrolidone and provide rapid disintegration to wet and dry granulations and direct compression tablet formulations.
