What Polyvinyl Butyral does

  • Forms a flexible, glossy film on nails or hair
  • Helps the coat stick to the surface
  • Helps a finish stay even and glossy

Polyvinyl Butyral is made by chemically linking polyvinyl alcohol with butyraldehyde, a simple aldehyde. The resulting resin is well known outside beauty too, where it forms the clear layer inside laminated safety glass.

In beauty, formulators use it as a film former. As the product dries, the polymer forms a thin, even coat that sticks to nails or hair and helps hold a look in place. The film is glossy and flexible, so it can bend with the surface instead of cracking as easily. It is used in some nail and hair styling products.

Good for

Suits nail polishes and hair styling products that need a long-lasting, flexible coat.
