Uses
PVP/VA E-735 is a water-soluble polymer used to improve the uptake and drug loading of various pharmaceutical agents, including contraceptive patches.
PVP/VA E-735 has a number of benefits to offer in the world of cosmetics and personal care.
PVP/VA E-735 can mainly be found in hair care products, followed by cosmetics and a few skin care products.
Skin care: PVP/VA E-735 is responsible for forming a thin layer on the skin that feels smooth to the touch and makes the surface look flawless.
PVP/VA E-735 also retains moisture on the skin and doesn't allow it to run dry for longer durations of time.
Hair care: PVP/VA E-735 is mainly used in hair care products for hair setting.
PVP/VA E-735 does not allow the shafts to absorb any further moisture and thus lose any styling done on them.
PVP/VA E-735 also forms a thin coat on hair that helps them retain its shape.
Decorative cosmetics: PVP/VA E-735 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.
The main raw material ofcosmetics, used in hairgel, mousse, shampoo, etc., and also used in surfactants, medicine and other industries
PVP/VA E-735 is mainly used as a water-solubleadhesiveand dry adhesive in granulation and direct compression technology, as a film-forming material in film coating, and as a channel former in taste-masking agents.
Applied to sugar coating to prevent splintering, and bottom coating to prevent moisture
PVP/VA E-735 series products are mainly used asfilm-formingagents and styling agents in the cosmetics field, especially in hair sprays, hair gels, mousses and shampoo products.
They play an important role as film formers and hair styling agents.
If used in conjunction with PVP/VA E-735, their effectiveness will be enhanced.
Pharmaceutical Applications
PVP/VA E-735 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 E-735 can be used as a binder for direct compression and as a binder in wet granulation.
PVP/VA E-735 is often added to coating solutions as a film-forming agent.
PVP/VA E-735 provides good adhesion, elasticity, and hardness, and can be used as a moisture barrier.
Production Methods
PVP/VA E-735 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.
