Introduction
γ-Polyglutamic acid is a water soluble, biodegradable, non-toxic biopolymer produced by microbial fermentation. γ-PGA is a sticky material first found in “natto”, a fermented soybean. γ-PGA 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. γ-PGA has a molecular weights ranging from 50,000 to more than 2 million Daltons.
CAS No. : 25513-46-6
Formula: L-Glu-(L-Glu)n-L-Glu
Functions
· 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.
Applications
γ - PGA and its derivatives have molecular weights ranging from 50,000 to more than 2 million Daltons, hence they have wide applications in food industry, cosmetics,health care, water treatment, waste water treatment, Hygiene products, Medical treatments, Hydrogels etc.
· Water treatment – Heavy metal absorbent or chelating agent.
· Waste water treatment – Biopolymer flocculant, a substitute for polyacrylamide.
· Health Care – Facilitates calcium absorption in osteoporosis cases.
· Hygiene products – As absorbent in Baby diapers, women’s tampons etc.
· Medical treatment – Drug release carrier, a haemostatic agent, soft tissue augmentation,.
· Cosmetics - As a humectant, moisturizer to improve skin care quality, as a whitening agent, has anti wrinkle property which gives long lasting effect.
