How to Select Optimum Preservatives for Liquid Formulation


Preservatives are a unique set of excipients that have a critical role to protect the degradation of formulation from microbial contamination and prolong the shelf life of formulation. Ideal preservatives should be non-toxic, inert, compatible, have wide-microbial activity, etc. The selection of preservatives is a very critical task because it depends upon multiple factors like the route of administrations, pH of formulation, type of formulation, toxicity, compatibility with other excipients, etc.

In this webinar, you will learn:

  • The selection basis for preservatives in pharmaceuticals
  • Critical aspects to be considered while screening different preservatives
  • pH and preservatives activity co-relation
  • Optimization of preservative action through synergistic action
