For procurement managers and R&D scientists in the chemical, food, and cosmetic industries, a thorough understanding of a product's specifications is vital before making a purchase decision. Epsilon Polylysine (EPL), identified by CAS 28211-04-3, is a high-value ingredient known for its exceptional antimicrobial properties. Sourcing this product requires attention to its key physical and chemical characteristics.

At NINGBO INNO PHARMCHEM CO.,LTD., we supply Epsilon Polylysine as a Milky White powder. This visual characteristic is a primary indicator of its quality and consistency. The specified purity levels for our EPL range from 95% to 99%, as determined by High-Performance Liquid Chromatography (HPLC). This high purity ensures that the product is free from significant impurities, making it suitable for demanding applications where product integrity is paramount.

Further critical specifications include Loss on Drying, which is typically maintained at ≤8.0%, indicating a low moisture content. The Residue on Ignition is kept ≤2.0%, reflecting minimal inorganic impurities. Trace metal content, such as Lead (≤2 mg/kg) and Arsenic (≤3 mg/kg), is strictly controlled to meet international safety standards. For microbiological applications, the Total Plate Count is kept ≤10 cfu/g, and the absence of specific harmful bacteria like Salmonella is confirmed.

The stability of Epsilon Polylysine is another significant advantage. It demonstrates excellent antimicrobial activity across a broad pH range (2-9) and remains stable even at high temperatures (up to 120°C for 20 minutes). This makes it an ideal preservative for products that undergo thermal processing or are formulated in varying pH environments.
