Aplicação

The Kollidon products consist of soluble and insoluble grades of polyvinylpyrrolidone (PVP) of various molecular weights and particle sizes. It is used as dry binders, film-formers, stabilizers in suspensions, dispersants for pigments, enzyme stabilisiers and bioavailablility improvers.
Kollidon SR is a blend of polyvinyl acetate and povidone (K 30) in the ratio 8:2 for use as matrix-forming agent. This research grade product is intended for use in R&D and development only.

Outras notas

A polivinilpirrolidona é um componente da solução de Denhardt e está incluída a uma concentração de 1% (p/v) na solução-estoque 50X padrão.

Reactive peroxides in povidone often lead to degradation of oxidation-labile drugs. To reduce peroxide concentration in povidone, the roles of storage conditions, antioxidants, and silicates were investigated. Povidone alone and its physical mixtures with ascorbic acid, propyl gallate, sodium sulfite
