Polylysine is a small natural homopolymer of the essential amino acid L-lysine that is produced by bacterial fermentation. ε-Poly-L-lysine is used as a natural preservative in food products.ε-Polylysine belongs to the group of cationic polymers. In water, ε-polylysine contains a positively charged hydrophilic amino group . According to research, ε-polylysine is adsorbed electrostatically to the cell surface of the bacteria, followed by a stripping of the outer membrane. This eventually leads to the abnormal distribution of the causing damage to the bacterial cell.
Polylysine has a broad spectrum of antibacterial properties, can effectively inhibit the growth of various microorganisms, to ensure the quality of the product Chemicalbook quantity. ε- polylysine is a polymer of amino acids, is a nutritional preservative, so more green, safe and efficient. Inoltre, ε -polylysine is also widely used in toothpaste, mouthwash, soap, hand sanitizer, wet wipes, kitchen cleaning agent, women's sanitary napkins, baby diapers and other daily chemical products.
