Large number of Carboxyl Groups along the molecule chain of Gamma PGA can form hydrogen bonding in a molecule or between different molecules.Thus it has high water absorbability and moisture retaining capability.Thanks to its unique properties,

Gamma PGA can be used as thickener,filmogen,humcctant,retarder,cosolvent,binder and anti-freezer,therefore,the application prospect of Gamma PGA is promising.
