VP/VA Copolymer is a film forming ingredient that works well in both skin/hair care products and cosmetics.
VP/VA Copolymer forms a film on the surface to trap and retain moisture for longer durations.
VP/VA Copolymer is found primarily in most hair care products, mascaras, nail polishes and also some skin care products.

Uses
VP/VA Copolymer is a water-soluble polymer used to improve the uptake and drug loading of various pharmaceutical agents, including contraceptive patches.
VP/VA copolymer is a synthetic polymer, or large molecule, used in skin care and hair care preparations primarily as a film-forming agent.
This category of ingredients creates a coating over the area of application which helps reduce transepidermal water loss (TEWL) and creates a smooth feeling.
VP/VA copolymer is created through the combining of two smaller molecules, vinyl acetate and polyvinylpyrrolidone (PVP).
Hair care products commonly use this multi-industry ingredient to help fix hair into place, which is why VP/VA Copolymer’s commonly incorporated into hair sprays.
VP/VA Copolymer has a number of benefits to offer in the world of cosmetics and personal care.
VP/VA Copolymer can mainly be found in hair care products, followed by cosmetics and a few skin care products.
Skin care: VP/VA Copolymer is responsible for forming a thin layer on the skin that feels smooth to the touch and makes the surface look flawless.
VP/VA Copolymer also retains moisture on the skin and doesn't allow it to run dry for longer durations of time.
Hair care: VP/VA Copolymer is mainly used in hair care products for hair setting.
VP/VA Copolymer does not allow the shafts to absorb any further moisture and thus lose any styling done on them.
VP/VA Copolymer also forms a thin coat on hair that helps them retain its shape.
Decorative cosmetics: VP/VA Copolymer is also added to cosmetic products like nail polish and mascara because it dries up to form a film that inhibits the surface from absorbing any moisture and thus keeps it styled impeccably.
Pharmaceutical Applications
VP/VA Copolymer is used as a tablet binder, a film-former, and as part of the matrix material used in controlled-release formulations.
In tableting, VP/VA Copolymer can be used as a binder for direct compression and as a binder in wet granulation.
VP/VA Copolymer is often added to coating solutions as a film-forming agent.
VP/VA Copolymer provides good adhesion, elasticity, and hardness, and can be used as a moisture barrier.
Production Methods
VP/VA Copolymer is manufactured by free-radical polymerization of vinylpyrrolidone and vinyl acetate in a ratio of 6 : 4.
The synthesis is conducted in an organic solvent owing to the insolubility of vinyl acetate in water.
