What’s Gohsenol EG?
Polyvinyl alcohol is a polyvinyl resin having hydroxyl groups
and is obtained through saponification of polyvinyl acetate.
GOHSENOL EG is a series of high-quality polyvinyl alcohols
with the Extra High purity property.
Make use of this character, GOHSENOL EG series are widely
used for the application of pharmaceuticals, cosmetics,
electronics materials and ceramics.

Moisture barrier coating
Many Pharmaceutical actives are degraded
by atomospheric agents such as
oxygen or light, particularly where there
are opportunities for the ingress of
atomospheric moisture during storage.
Coating system can be formulated to
provide, effective barrier to water vapor,
oxygen and light and can thus provide
an effective means of improving stability
and increasing product shelf life.
