PVP-VA-Copolymer
·Chemical Name: Copolymer of
Vinylpyrrolidone and vinylacetate
·INCI/CTFA Name: PVP/VA
Copolymer
·CAS No. : *********9
·Molecular
Structure: (C6H9NO)n(C4H6O2)m(n=1.2m)
·Properties:
White or creamy white, free-flowing power with characteristic
smell, hygroscopic. Soluble in water, alcohol and other organic
solvents, has good cohesiveness, hygroscopic, film forming and
surface activity character. The clarity of the aqueous product
depend on the proportion of vinylpyrrolidone and vinylacetate.
The aqueous solution of VA*7 is cloudy,and the others are clear
at room temperature. The solution is slight acidic but not
electrolytic.

·Applications:
Cosmetics:
PVP/VA series products play a good role as film-former and
hair-fixing agent. Its hydrophobe decreases with the increase
in the proportion of vinyl acetate in the molecular. This
property is extremely useful for PVP/VA as hair sprays and
hairset lotion. If mix with PVP-K*0 can strengthen casehardened
effect
Other
Utility:
*-Binding agent: used in wet granulation processes.
*-Dry binding agent: used in direct compression tablet
processes.
*-Film coating agent: used for film promoters and sugar coating
to prevent splitting,bottom binder to prevent moisture
sensitivity.
*-Crazing agent: acts in taste preparating and
coating films.
Packaging and storage:
*-Packed in *0kg fibre drum or plastic drum, inner lined with
PE bags.
*-Stored in dry place at room temperature.
