Vp/Eicosene Copolymer

What is Vp/Eicosene Copolymer?

VP/Eicosene Copolymer is a synthetic vinyl polymer produced through the copolymerization of N-vinyl-2-pyrrolidone and eicosene, a branched C20 alpha-olefin. This clear, viscous liquid ingredient falls into the category of multifunctional additives widely employed in hair styling products, makeup, and nail formulations. Upon application and solvent evaporation, it creates a sheer, flexible, non-tacky film on skin, hair, or nails that boosts adhesion and resistance to water, smudging, or rubbing. In formulations, it binds powders into cohesive forms, suspends pigments or pearls evenly, and modifies flow properties to prevent separation and ensure smooth spreadability. Its compatibility with various solvents allows use in sprays, gels, and emulsions, contributing to product durability and user-friendly textures without adding weight or residue.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

Binder
Helps hold solid ingredients together to form cohesive tablets, compacts, or sticks, improving pressability, integrity, and wear of the finished product.
Film former
Creates a continuous film on skin or hair to improve wear, water resistance, transfer resistance, shine, or hold in sunscreens, makeup, and styling products.
Suspending agent
Keeps insoluble particles (pigments, beads, actives) evenly dispersed by increasing viscosity or forming a network, preventing settling and separation.
Viscosity controlling agent
Adjusts thickness to the desired level for stability and usability, improving dispensing, suspension, and texture across many formulation types.
Binding
Provides cohesion by helping ingredients stick together, improving the strength and integrity of pressed powders, tablets, or solid bars.

Benefits

Forms a protective film to extend makeup and hair product wear.

Stabilizes formulations by suspending particles and controlling thickness.

Binds ingredients for stronger, more intact solid cosmetics.
