Crospovidone (cross linked polyvinyl N-pyrrolidone, or PVP) is a common, FDA-approved inactive ingredient used in the pharmaceutical industry.



  • Crospovidone is often combined with active ingredients in medications and dietary supplements to allow absorption of the active drug. It is considered a synthetic povidone analog.
  • As a food additive, PVP is a stabilizer and has E number E1201. PVPP (crospovidone) is E1202. It is also used in the wine industry as a fining agent for white wine or some beers. Other references state that polyvinyl pyrrolidone and its derivatives are fully from mineral synthetic origin. Therefore, its use in the production should not be a problem for vegans.


  • The U.S. Food and Drug Administration (FDA) has approved this chemical for many uses, and it is generally considered safe. However, there have been documented cases of allergic reactions to PVP/povidone, particularly regarding subcutaneous (applied under the skin) use and situations where the PVP has come in contact with autologous serum (internal blood fluids) and mucous membranes.
