Reagent-grade Polylysine | Naturally occurring cationic polymer produced by fermentation
In response to your requests, we have started selling reagents. This is a cationic polymer produced through fermentation that can be used in food preservatives, sanitary materials, and daily necessities.
ε-Polylysine (hereafter referred to as Polylysine) is a substance officially known as ε-Poly-L-lysine. It has over 30 years of manufacturing history since 1989 and is widely used as a preservative in food. Polylysine is a natural food preservative produced through fermentation. Due to its high safety, we have received numerous requests to use it for various antibacterial applications. In response to customer feedback, we have started selling it as a reagent. The reagent can be purchased from Fujifilm Wako Pure Chemical Corporation. For example, it is expected to reduce synthetic polymers in everyday products closely related to daily life, such as wet wipes, toothpaste, shampoo, and scalp care. 【Features】 ■ Safe natural microbial fermentation product (not genetically modified organism) ■ 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 *For more details, please download the PDF or feel free to contact us.
