ε-Polylysine, with the CAS number 28211-04-3, is a natural antimicrobial peptide. It is a polymer composed of L-lysine units linked by ε-amide bonds. Our Factory Supply ε-Polylysine offers high - quality at a low price, meeting the needs of various industries.
Appearance: It usually presents as a white to slightly yellowish powder. Solubility: It is highly soluble in water, which makes it convenient for use in aqueous systems. Stability: It has good stability under a wide range of pH values (2 - 9) and temperatures, ensuring its effectiveness in different environmental conditions.
The molecular weight of ε-Polylysine typically ranges from 3000 - 4500 Da, and the purity of our product can reach up to 95% or higher, which ensures its strong antimicrobial activity.
Food Industry: ε-Polylysine is widely used as a natural preservative in the food industry. It can inhibit the growth of various microorganisms, including bacteria, yeasts, and molds. It can be used in meat products, dairy products, beverages, and canned foods to extend their shelf - life and maintain food quality.
Pharmaceutical Industry: In pharmaceuticals, it can be used in the formulation of topical creams and ointments. Its antimicrobial properties help prevent infections in wounds and skin diseases. It can also be used in oral formulations to prevent microbial contamination during storage.
Cosmetics Industry: Due to its mildness and antimicrobial activity, ε-Polylysine is added to cosmetics such as lotions, shampoos, and soaps. It can protect cosmetics from microbial spoilage and ensure product safety for consumers.
Food Application: When using ε-Polylysine in food, it can be dissolved in water first. The recommended dosage is generally 50 - 200 ppm, depending on the type of food and the expected shelf - life. For example, in meat products, it can be added during the marinating process. In beverages, it can be added during the blending stage.
Pharmaceutical Application: In topical formulations, ε-Polylysine is usually added to the final emulsion or solution at a concentration of 0.1% - 1%. For oral formulations, it can be added during the granulation or mixing process, and the dosage should be determined according to the specific requirements of the product.
Cosmetics Application: In cosmetics, it is typically added at a concentration of 0.05% - 0.2% during the manufacturing process. It should be added after the main ingredients have been mixed well to ensure uniform distribution.
Case 1: A meat processing company used our ε-Polylysine in its sausage products. Before using ε-Polylysine, the sausages had a shelf - life of about 7 days at refrigerated temperatures. After adding 150 ppm of ε-Polylysine during the marinating process, the shelf - life was extended to 14 days. The sensory quality of the sausages, such as color, flavor, and texture, remained unchanged during the extended storage period, which significantly reduced product losses due to spoilage.
Case 2: A pharmaceutical company used ε-Polylysine in a topical cream for treating acne. The cream contained various active ingredients for acne treatment. By adding 0.1% ε-Polylysine, the cream was protected from microbial contamination during storage. Clinical trials showed that the cream remained effective in treating acne without any signs of microbial growth even after 6 months of storage at room temperature.
Case 3: A cosmetics company added 0.1% ε-Polylysine to its shampoo product. Before using ε-Polylysine, the shampoo had a high risk of microbial spoilage during storage and transportation. After the addition of ε-Polylysine, the shampoo passed all microbial tests during its 1 - year shelf - life, and consumers reported no issues related to product quality or safety.
