γ-PGA, CAS:25513-46-6 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-PGAis 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.

Properties:

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.

· Food industry - as thickener for foods & drinks, improves taste of drinks, stabilizer in ice creams, texture enhancer, binder, animal feed supplement, antifreezing agent or cryoprotectant, bitterness relieving agent, as an additive in preparation of starch foods (bakery & noodles) for avoiding staling, enhancing food texture and maintaining food shapes.   

· 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.

 Advantages over other commercial available polymers:

· 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.   

· γ-PGA derivatives have excellent strength, transparency and elasticity.

 γ-PGAcan be used in skin care products, shampoo, hair lotion, shaving cream and lipsticks
