Product introduction：
Polyglutamic Acid powder is a kind of polymer formed by connecting glutamic acid monomers through γ -peptide bonds. It is a naturally occurring biopolymer with excellent moisture retention, biocompatibility and biodegradability. Polyglutamic acid powder can be obtained by microbial fermentation in nature, especially some bacteria such as Bacillus subtilis can produce this polymer. It can absorb and keep water many times its own weight, so it is widely used as a humectant. Polyglutamic acid can be decomposed by microorganisms in the natural environment and will not cause long-term environmental pollution. It is friendly to human tissues, does not cause immune response, and is suitable for medicine and food industries. Polyglutamic acid has good stability in a certain pH value and temperature range.
Preparation process of polyglutamic acid powder：
Microbial fermentation: First, select a microbial strain that can produce polyglutamic acid, such as Clostridium Pasteureum. This strain was inoculated into a culture medium containing glutamic acid and cultured under suitable temperature and pH conditions. During the fermentation process, microorganisms secrete special enzymes to catalyze the polymerization of glutamic acid molecules to form polyglutamic acid.
Collecting polyglutamic acid: after fermentation, microbial cells and other impurities in the culture medium are removed by centrifugation, filtration and other steps to obtain a solution containing polyglutamic acid.
Extraction of polyglutamic acid: the solution containing polyglutamic acid is precipitated by acid or alcohol to precipitate polyglutamic acid from the solution. Then the precipitated polyglutamic acid is collected by centrifugation or filtration.
Drying: drying the collected polyglutamic acid at low temperature to obtain polyglutamic acid powder.
The role of polyglutamic acid powder in cosmetics：
Moisturizing: Polyglutamic acid powder can absorb and lock a lot of water, which is stronger than hyaluronic acid (HA). The hydration layer formed by it can maintain the moisture of the skin for a long time, thus effectively preventing the skin from drying and improving the moisture retention of the skin.
Increase skin elasticity: Because of its excellent moisturizing effect, polyglutamic acid helps to increase skin elasticity, reduce the appearance of fine lines and wrinkles, and make skin look younger and more energetic.
Forming protective film: The moisturizing film formed by polyglutamic acid on the skin surface can not only lock water, but also provide some protection for the skin and reduce the influence of harmful substances and environmental pollution on the skin.
Promote the absorption of nutrients: Polyglutamic acid can enhance the absorption of nutrients in other skin care products, such as vitamins and minerals, and further enhance the efficacy of cosmetics.
Thickening and stability: polyglutamic acid can also be used as thickener to increase the stability of consistency and texture in emulsion and cream products.
Safety and biocompatibility: Polyglutamic acid is also a safe choice in care products for sensitive skin because of its good biocompatibility and low toxicity.
Benefits of polyglutamic acid powder on skin：
Deep moisturizing: Polyglutamic acid powder can absorb and keep a lot of water, and its moisturizing ability far exceeds that of traditional humectants such as hyaluronic acid. This efficient moisturizing effect helps to keep the skin moist and prevent dryness and peeling, thus keeping the skin soft and smooth.
Improve skin elasticity: Because of its excellent moisture retention, polyglutamic acid can help increase skin elasticity and slow down skin relaxation and fine lines caused by dryness or aging.
Promote epidermal repair: maintaining a good skin moisture balance is the key to promote skin self-repair and regeneration. Polyglutamic acid contributes to the normal function and metabolism of skin cells by providing sufficient water, thus promoting the healthy state of skin.
Form a protective layer: the moisturizing film formed by polyglutamic acid on the skin surface not only locks moisture, but also acts as a barrier to reduce the damage of environmental pollution, dust and other potential irritants to the skin.
Reduce irritation: For sensitive skin, polyglutamic acid is not easy to cause skin irritation because of its natural and gentle characteristics, and is suitable for use in care products for sensitive skin.
Enhance the absorption of other ingredients: Polyglutamic acid can help the skin to better absorb other maintenance ingredients, such as antioxidants such as vitamin C and E, thus enhancing the efficacy of the whole skin care product.
Application of polyglutamic acid powder
Cosmetic industry: Polyglutamic acid is widely used as humectant, thickener and stabilizer in cosmetics because of its excellent moisturizing performance and good biocompatibility. It can form a moisturizing film on the skin surface, effectively lock moisture, reduce moisture evaporation, and provide delicate skin touch.
Medical field: In the medical field, polyglutamic acid can be used to manufacture drug sustained-release agents, wound healing materials and tissue engineering scaffolds. Its biodegradability and biocompatibility make polyglutamic acid an ideal biomedical material.
Food industry: Polyglutamic acid can be used as a food additive to improve the texture, stability and moisture retention of food. It is often used as thickener, emulsifier and humectant, and is widely used in food processing such as bean products, pasta and beverages.
Agriculture: polyglutamic acid can also be used in agriculture as a soil improver or a plant growth promoter. It can help the soil keep water, improve the drought resistance of crops and promote the development of plant roots.
Water treatment: Because polyglutamic acid has good flocculation and adsorption capacity, it can be used in water treatment process to help remove suspended solids and heavy metal ions from water.
Bioplastics: Because of its biodegradability, polyglutamic acid can be used to produce bioplastics, and as a kind of environmental protection materials, it can be used to make degradable plastic bags and packaging materials.
Textiles: In the textile industry, polyglutamic acid can be used as anti-wrinkle agent and humectant for fabrics, which can improve the comfort and wearing experience of fabrics.
Application of polyglutamic acid powder in agriculture
Soil humectant: Polyglutamic acid can be used as a soil humectant to improve the water retention capacity of soil. It can absorb a lot of water and release it slowly under drought conditions, thus helping plants to survive and grow in a water-deficient environment.
Plant growth promoter: Studies show that polyglutamic acid can promote plant growth. It can improve the root development of plants and increase the absorption efficiency of water and nutrition by roots.
Fertilizer additive: Polyglutamic acid can be used in combination with fertilizer as a slow-release carrier of fertilizer. It helps to reduce the loss of fertilizer, improve the utilization rate of fertilizer and reduce the impact of fertilizer on the environment.
Seed coating agent: using polyglutamic acid as seed coating agent can protect the survival rate of seeds in adverse environment and increase the germination rate of seeds and the survival rate of seedlings.
Anti-adversity treatment agent: polyglutamic acid can also be used as an anti-adversity treatment agent for plants to help them resist adverse environmental conditions such as drought and salinity.
Water management: As a soil conditioner, polyglutamic acid can effectively control the water state in the soil and improve irrigation efficiency in arid areas or in modern agricultural production that requires precise water management.
