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 (hereafter referred to as Polylysine) is a homopolymer consisting of 25 to 35 linked ε-amino groups of L-lysine, an essential amino acid for humans, and α-carboxyl groups through 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 sanitary materials and more. For example, it is expected to reduce synthetic polymers in everyday items closely related to daily life, such as wet wipes, toothpaste, shampoo, and scalp care products. Even in the presence of chelating agents used as antioxidants in cosmetics, various detergents, chemicals, and pharmaceuticals, it exhibits excellent antibacterial properties. Additionally, it is utilized in preventing bacterial contamination during the manufacturing process of food raw materials, removing anionic substances by leveraging the characteristics of cationic polymers, and in applications for 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, sanitary materials, and daily necessities ■ A safe domestic product ■ A natural cationic polymer
