Polylysine is a kind of Polypeptide Amino Acid with broad spectrum antibacterial activity, works against gram positive and gram negative bacteria, yeast & molds, viruses etc. Now Polylysine is used in cosmetics, personal care, disinfectionby preventing growth of microorganisms.
ε-polylysine is found in nature, a material produced by microbial fermentation and combined to a straight chain of lysine which is one of an essential amino acid.

Q. What is polylysine and how does it work?
A. Polylysine is simply a chain of lysine molecules produced by fermentation. This chain of lysine has a strong charge that attracts it to mold, yeasts & bacteria, attacking these microbes and knocking them out.
Q. Is Polylysine safe?
A. Polylysine is 100% natural and extremely safe – safer than the salt on your dinner table (LD50 for Polylysine is more than 5g/kg vs. 4g/kg for NaCl). It’s GRAS by the US FDA for a wide variety of applications and approved for use in food in Japan in Korea, where it’s been used for over 20 years.
Q. How much Polylysine do I need in my application?
A. It varies based on your application, condition, and your expectations, but generally 20-250ppm is recommended. In some applications, Polylysine works best in combination with other preservatives. Our sales staff can give you information specific to your application.
Q. Why Polylysine?
A. Polylysine is unique in that it’s natural and works where others don’t – on pathogens, mold and yeast. All this and it’s virtually flavorless and odorless – providing the extra “bump” you need to your existing preservative system or replacing it altogether.
Q. Where does Polylysine work best?
A. Polylysine works best with moist foods of neutral to higher pH and higher temperature (that’s right, HIGHER pH and temperature are NO PROBLEM for Polylysine). Polylysine can be refrigerated, frozen, boiled, baked and gets right to work when it needs to.
