Povidone /PVP/Polyvidone INCI /CTFA

CAS No. : 9003-39-8

EINECS No. : 1312995-182-4

Chemical Formula: (C₆H₉NO)n

Introduction

PVP (Polyvinylpyrrolidone) is white or milky white to light

yellow free-flowing powder or clear transparent viscous

liquid, which is odorless or has slight characteristic odor. PVP is non-toxic,nonirritant and has moisture absorption.

Application

It is easy soluble in many organic solvents like water, alcohol, amine and halohydrocarbon; insoluble in

acetoner and diethyl r. PVP has excellent solubility, biocompatibility, film-forming property, chemical stability,physiological inert,cohesiveness, membrane protection ability, complexing ability to many organic

and inorganic compounds, good stability to acid, salt and heat and therefore has wide applications in many

fields.
