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 it’s commonly incorporated into hair sprays.

Application of VP/VA Copolymer
Pharmaceuticals
It is mainly used as water soluble and drying adhesive agent when making grain and pressing tablet directly. It will be used in film coating and cover-taste agent. It can prevent sugar coating from split and make bottom coating avoid dampness.
Cosmetics
VP/VA Series play a good role in film-former and hair-fixing agent. Its hygroscopicity decreases with the increase of the proportion of vinylacetate in the molecular. This property of VP/VA is extremely useful as it works in hair sprays and hair-set lotion. If it is mixed with PVP K-30, the effect of hair-fixing would be changed a lot.
Other Utility
VP/VA series can be used in remoistenable adhesive and other adhesives for paper or viscosity-enchancing agent and protecting colloid for printing ink. VP/VA series can also act as emulsifying agent, protecting colloid for planting-protecting chemicals, other dispersing systems and binder in coating.
