PVP/VA Copolymer produce transparent, flexible, oxygen permeable films which adhere to glass, plastics and metals.
PVP/VA Copolymer resins are linear, random copolymers produced by the free-radical polymerization of the monomers in ratios varying from 70/30 to 30/70 vinyl acetate to vinylpyrrolidone.
PVP/VA Copolymer are available as white powders or clear solutions in ethanol, isopropanol and water.
CAS NO : 25086-89-9
PVP/VA Copolymer in the four ranges of vinylpyrrolidone content (30, 50, 60 and 70 percent), are produced in ethanol or isopropanol.
The PVP/VA Copolymer with 60 and 70 percent vinylpyrrolidone content are available as solids or as 50 percent aqueous solutions.
PVP/VA Copolymer is the ingredient found in most mainstream hair care products that provides the hold factor.
So PVP/VA Copolymer is very common in most Hairsprays but also found in gel’s, wax’s, pomades and styling creams.
PVP/VA Copolymer is a synthetic ingredient that is derived from petroleum.

PVP/VA Copolymer was the main ingredient in the first really successful hairsprays in the early 1950s.
PVP/VA Copolymer worked as a hairspray because it was soluble in water.
This meant PVP/VA Copolymer could be rinsed out when you wash your hair.
PVP/VA Copolymer tended to absorb water out of the air, giving hair that tacky look that was so common in the sixties.
PVP/VA Copolymer was fixed with the help of another polymer, a silicone called polydimethylsiloxane.
To understand how this silicone made a better hairspray, PVP/VA Copolymer helps to understand how the hairspray works in the first place.
When you spray PVP/VA Copolymer on, the polyvinylpyrrolidone forms a thin coating on the hair.
This coating is stiff and keeps the hair from moving around.
Unfortunately no one was aware of the dangers that came with PVP/VA Copolymer.
If particles of PVP/VA Copolymer are inhaled, PVP/VA Copolymer can cause damage to the lungs in sensitive individuals.
PVP/VA Copolymer can be considered toxic, since particles may contribute to foreign bodies in the lungs of people.
Up until a few years ago, this ingredient was considered safe to use however now iPVP/VA Copolymer is definitely an ingredient that is better to avoid.
PVP/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, PVP/VA Copolymer can be used as a binder for direct compression and as a binder in wet granulation.
PVP/VA Copolymer is often added to coating solutions as a film-forming agent.
PVP/VA Copolymer provides good adhesion, elasticity, and hardness, and can be used as a moisture barrier.
PVP/VA Copolymer is used widely in pharmaceutical formulations and is generally regarded as nontoxic.
However, PVP/VA Copolymer is moderately toxic by ingestion, producing gastric disturbances.
PVP/VA Copolymer has no irritating or sensitizing effects on the skin.
A study was conducted to look at the carcinogenicity and chronic toxicity of PVP/VA Copolymer in Wistar rats and Beagle dogs.
The results of these studies demonstrated the absence of any significant toxicological findings of high dietary levels of copodivone in rats and dogs, resulting in noobserved- adverse-effect levels of 2800 mg/kg body-weight/day in rats and 2500 mg/kg body-weight/day in dogs, the highest doses tested.
PVP/VA Copolymeris a film forming ingredient that works well in both skin/hair care products and cosmetics.
PVP/VA Copolymer forms a film on the surface to trap and retain moisture for longer durations.
PVP/VA Copolymer is found primarily in most hair care products, mascaras, nail polishes and also some skin care products.
The full form of PVP/VA Copolymer is vinylpyrrolidone/vinyl acetate copolymer, which appears as a white powder in its raw form.
