Polylysine
ε-Polylysine from Twin International Co., Limited is a naturally derived biopreservative produced via fermentation, widely adopted in food, beverage and cosmetic formulations for its broad-spectrum antimicrobial activity. The polymer, with the chemical formula (C6H12N2O)n, inhibits the growth of Gram-positive and Gram-negative bacteria, as well as yeasts and molds, extending shelf life without altering sensory properties. Supplied as a fine powder or liquid solution, it meets FCC and cosmetic-grade standards for safety and purity.
The material is highly hygroscopic, requiring moisture-controlled storage and handling to prevent agglomeration or degradation. Standard food-grade ε-Polylysine typically exhibits a molecular weight range of 3,000 to 4,000 Da, with a minimum assay purity of 96 % as confirmed by HPLC. It is soluble in water and dilute acids but insoluble in organic solvents, making it suitable for aqueous-based applications. Typical usage levels in food range from 0.01 % to 0.05 %, depending on the product’s pH and microbial load.
Manufacturers in the dairy, meat, bakery and cosmetic sectors use ε-Polylysine to replace or reduce synthetic preservatives, aligning with clean-label trends. The additive is traded globally in 25 kg fiber drums or liquid totes, with Twin International Co., Limited sourcing from verified production facilities in China. Buyers should confirm the grade (food or cosmetic) and regulatory compliance for their target markets before import.

Sourcing ε-Polylysine from Twin International Co., Limited - China Import Guide
Before placing an order, confirm the grade of ε-Polylysine (food or cosmetic) and request a certificate of analysis to verify assay purity, molecular weight, and microbial limits. Check that the supplier can provide documentation for regulatory compliance in your target markets, as requirements may differ by country. For liquid formulations, request details on preservative content and stability under your storage conditions.
Logistics should be discussed with the supplier to confirm packaging options, such as 25 kg fiber drums or liquid totes, and their suitability for your handling equipment. Clarify incoterms like FOB Shanghai or CIF to your port, and agree on lead times for production and shipping. Payment terms, such as T/T or L/C, should be negotiated in advance to align with your procurement process.
Quality checks should include testing for solubility, pH, and antimicrobial efficacy using standard methods such as agar diffusion or challenge tests. Request a sample for compatibility testing in your formulation, as ε-Polylysine’s performance can vary with pH and other ingredients. Documentation should include material safety data sheets, allergen statements, and certificates of conformity to ensure traceability and compliance.
