Model Number : jgasOrigin : Mainland ChinaModel Number : jgasOrigin : Mainland ChinaProduct Description:Polyglutamic acid( - PGA), which is a water-soluble, biodegradable, non-toxic biopolymer prepared by microbial fermentation,Molecular formula: L-Glu - (L-Glu) n-l-glu molecular weight: 700000 units CAS No.: 25513-46-6 PGA full name - Polyglutamic acid takes left-handed and right-handed optical glutamate as the unit and takes - Homo polypeptide is formed by polymerization of amide bond at position, and the degree of polymerization is about 1000-15000. - (D,L)-PGA, - (D) - PGA, and - (50) - PGA and others are collectively referred to as - PGA . PGA is named natto gum in the international cosmetic Pharmacopoeia, and also known as plant collagen, collagen, vegetale and phyto collagen in the European Union and Japan. In China, it is called natto gum or polyglutamic acid, polyglutamic acid.Polyglutamic acid (polyglutamic acid)- - Glutamic acid, English poly- - Glutamic acid (PGA) is a water-soluble poly amino acid produced by microbial fermentation in nature. Its structure is glutamate unit - Amino and - A high molecular polymer in which carboxyl groups form peptide bonds.The molecular weight ranges from 100 kDa to 10000 kDa. Gather- - Glutamate has excellent water solubility, super adsorption and biodegradability. The degradation product is pollution-free glutamate. It is an excellent environmental friendly polymer material. It can be used as water retaining agent, heavy metal ion adsorbent, flocculant, slow-release agent and drug carrier. It has great commercial and social value in cosmetics, environmental protection, food, medicine, agriculture, desert treatment and other industries.Polyglutamic acid, also known as natto gum, is a substance that can dissolve water and can be converted into microbial polymer materials after alcoholization. For the physical and mental health of the human body, it has a certain effect of health care. For example, it has a certain practical effect of beauty and beauty, which can improve the ductility of the skin. In addition, it also has a very good practical effect of moisturizing and hydrating. The effect of promoting the physical and mental health of the skin is relatively goodIt is only a few decades since the discovery of polyglutamic acid. The research of polyglutamic acid is mainly in the laboratory stage, mainly including the research on its properties, the improvement and gene research of producing bacteria, the research on fermentation process, extraction and purification process, and the research on the production and properties of derivatives. In recent years, due to the enhancement of people's environmental awareness and the requirements of the national sustainable development strategy, the development of environment-friendly materials and the development of products to improve environmental problems has become an industrial trend, which also promotes the process of research and exploration of polyglutamic acid industrialization. In this century, some international well-known companies began to carry out research on the production and application of polyglutamic acid, some domestic universities and research institutes also actively carried out relevant research, and several domestic enterprises began to plan the large-scale production of polyglutamic acid. Due to the follow-up of these industrialization studies, polyglutamic acid has become one of the most concerned biological products at this stage.- PGA polyglutamic acid is a kind of viscous substance, which was first found in natto, the fat alcohol bean. - PGA polyglutamic acid is a unique cationic polymer - Amino group( - Amino) and - Carboxyl group( - Homo polyamide resin composed of amidelinkage in the middle of caboxyl) - The relative molecular weight of PGA varies from 50000 to 2 million daltons. Its moisturizing effect is 500 times that of hyaluronic acid.- PGA is a multi-functional ingredient that integrates moisturizing, whitening, bacteriostasis and improving skin health. While rapidly realizing deep penetration and moisturizing, PGA comprehensively inhibits the generation of melanin, desalinates color spots, continuously decomposes aged horniness and keeps skin fresh and tender.- The main effects of PGA polyglutamic acid on skin in cosmetics are as follows:1. Functional long-term moisturizing, helping the skin resist the dry environment.2. Increase the elasticity of the skin and improve the smooth and tender touch of the skin.3. Inhibit skin melanin production.4. Maintain healthy pH value of skin.5. Form a slow-release delivery system to make the skin absorb various skin nutrients in the skin care products more efficiently.6, PGA is a multi-functional ingredient that integrates moisturizing, whitening, bacteriostasis and improving skin health. While rapidly realizing deep penetration and moisturizing, PGA comprehensively inhibits the generation of melanin, desalinates color spots, continuously decompos
