* Poly-L-glutamic Acid, CAS:25513-46-6 γ-Polyglutamic acid  is a water soluble, biodegradable,non-toxic biopolymer produced by microbial fermentation.

* Poly-L-glutamic Acid is a sticky material first found in “natto”, a fermented soybean.

* Poly-L-glutamic Acid  is an unusual anionic, naturally occurring homo polyamide that is made of D & L glutamic acid units connected by amide linkages between alpha amino & gamma carboxylic acid groups.

CAS:25513-46-6 γ-PGA  has a molecular weights ranging from 50,000 to more than 2 million Daltons.



. Non toxic towards humans and environment   

· Biodegradable, hence eco friendly   

· Water soluble, gives non odorous clear transparent solution   

· Can be easily cross linked to form hydro gels which further have excellent properties   

· Can be prepared in Na, Ca, Mg, H forms.



* Non toxic, Biodegradable and degraded end products are glutamates which are nutritional ingredients to skin.   

*Fully compatible with all skin conditions and provide long lasting moisturizing effect better than HA (Hyaluronic acid ) and  Collagen

*Is required in very less concentration hence cost effective.
