Natural amino acid 'Polylysine' as an additive in food preservatives, hygiene materials, and daily necessities. Examples of the use of Polylysine in antibacterial coatings are introduced.
ε-Polylysine (hereinafter referred to as Polylysine) is a substance formally known as ε-poly-L-lysine. It is a homopolymer consisting of 25 to 35 units linked by amide bonds, formed from the ε-amino group of the essential amino acid L-lysine and the α-carboxyl group. Since 1989, it has over 30 years of manufacturing history and is widely used as a food preservative amino acid. By uniformly dispersing Polylysine in aqueous emulsion resin, an antibacterial paint can be obtained that has low environmental impact from volatile organic compounds (VOCs) and high safety for human health. This introduces the antibacterial effects against Escherichia coli, Staphylococcus aureus, and Bacillus subtilis of polypropylene sheets coated with polyvinyl butyral resin dispersed with Polylysine. Sheets coated with polyvinyl butyral resin containing Polylysine exhibit antibacterial effects that depend on the amount of Polylysine in the coating film against each microorganism. *For more details, please download the PDF or feel free to contact us.
