Polylysine | A natural cationic polymer that can also be used for non-food applications.
Amino acid-derived natural cationic polymer that can be used in food preservatives, hygiene materials, and daily necessities. It is a safe material as it is a fermentation product produced by natural microorganisms.
ε-Polylysine (hereinafter referred to as polylysine) is a homopolymer consisting of 25 to 35 units formed by the amine group at the ε position and the carboxyl group at the α position of the essential amino acid L-lysine in humans, linked by amide bonds. With over 30 years of manufacturing experience, it is an amino acid-derived preservative widely used as a food preservative, making it applicable in hygiene materials and other areas. Polylysine possesses unique properties as a natural cationic polymer. In addition to its use as a food preservative, it is utilized in various industries. For example, it is used to prevent microbial contamination during the manufacturing process of food raw materials, to remove anionic substances by leveraging the characteristics of cationic polymers, and in applications related to electronic materials and semiconductor manufacturing. 【Features】 - A safe material produced through fermentation by natural microorganisms (not genetically modified organisms) - Provides a positive image as a natural fermentation product - Listed in the existing additive inventory as a food preservative - Can be used as an additive in cosmetics, hygiene materials, and daily necessities - A safe domestic product - A natural cationic polymer
