PVP: What It Is and Why It's Used

Origin

Polyvinylpyrrolidone (PVP) was first synthesised by Walter Reppe at BASF in Germany in 1938. It was developed during World War II as a plasma expander — a substitute for blood plasma in transfusions — before its utility in other applications was recognised. Its cosmetic use as a hair fixative dates from the 1950s.

Why It's Used

PVP is a water-soluble polymer that forms a flexible, clear film when dry. In mascara it acts as a film former and binder, helping pigments adhere to lashes and resist smudging. In hair products it is the active fixative in most traditional hairsprays. Its film is softened and removed by water.

Elsewhere

PVP is used in pharmaceuticals as a binder in tablet formulations, as a drug solubiliser, and as a wound-healing component. It is used in technical applications including textile sizing, adhesive formulations, and as a clarifying agent in wine and beer production.
