產品描述

γ-PGA, CAS25513-46-6
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-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. CAS25513-46-6
 γ-PGA  has a molecular weights ranging from 50,000 to more than 2 million Daltons.
Applications
  Structure:
γ-Polyglutamic acid
γ-PGA Powder
γ-PGA Hydrogel
 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.

γ-聚谷氨酸(γ-PGA),它是一種水溶性,生物降解,不含毒性,使用微生物發酵法制得的生物高分子。γ-PGA是一種有粘性的物質,在“納豆”——發酵豆中被首次發現。它是一種特殊的陰離子自然聚合物,它是通過α-氨基&γ-羧酸基團之間的酰胺鍵將D&L谷氨酸分子
特性: 
  · 對人體和環境無毒
  · 可生物降解,生態友好型
  · 水溶性,可得到無味清潔透明的溶液
  · 易交聯形成後期擁有卓越性能的水凝膠
                      
應用領域
    - PGA及其衍生物的分子量不等從5萬到2百萬道爾頓不等,因此他們可廣氾的應用在食品工業、化妝品、保健、水處理、廢水處理、衛生用品、醫療以及水凝膠等領域。 
   · 保健——有利於骨質疏鬆症者對鈣的吸收。
  · 醫藥——釋放藥物的載體,止血劑,軟組織填充劑。.
  · 化妝品——作為一個保濕劑以改善皮膚護理質量,作為增白劑具有長期持久的抗折皺的性能。
  
比其他聚合物商品更具優勢: 
  · 谷氨酸是無毒,可生物降解和退化,對皮膚有營養成分的高端產品。
  · 完全適用於所有的皮膚狀況,並提供優于HA(透明質酸)和膠原的持久的保濕效果
  · 只需要很低的濃度,因此成本降低。
  ·- PGA衍生物具有良好的強度,透明度和彈性。
   γ-聚谷氨酸可用於護膚產品、洗發水、發乳、剃須霜和口紅中。
 
γ-PGA(γ-聚谷氨酸)及γ-PGA Hydrogel(γ-聚谷氨酸水膠)
在化妝保養品上的應用
  γ-PGA是組成納豆粘性膠體的主要成份,具有促進礦物質吸收的作用,日本已將其列入促進礦物質吸收的保健成份表。γ-PGA特殊的分子結構,使其具有極強的保濕能力,添加γ-PGA于化妝品或保養品中,能有效地增加皮膚的保濕能力,促進皮膚健康,其超強的保濕能力更優于玻尿酸(hyaluronic acid, HA)以及膠原蛋白(Collagen),為新一代的生物科技保濕成份。
 γ-PGAγ-聚谷氨酸)的化學結構
  γ-PGA全名γ-Polyglutamic acid,是以左、右旋光性的谷氨酸為單元體,以γ-位上的醯胺鍵聚合而成同質多肽(Homo-polypeptide),聚合度約在1,000-15,000之間。γ-(D,L)-PGA,γ-(D)-PGA,和γ-(L)-PGA等統稱為γ-PGA。γ-PGA在國際化妝品藥典上的命名為納豆膠(NATTO GUM),在歐盟、日本也稱為plant collagen, collagene vegetale, phyto collage。在中國則稱為納豆菌膠或多聚谷氨酸。
