    Epsilon Polylysine

    Epsilon Polylysine Introduction

    Epsilon Polylysine is a naturally produced, cationic homopolymer of 25-30 L-lysine(due to Streptomyces albulus fermentation.), which was connected by ε-amido bond compounded by a e-amido of l-lysine and a e-carboxyl of another l-lysine.

     

    Characteristics

    ◆Various functions: Polylysine molecules are cationic, surface active agents in water due to their positively charged amino groups. This property imports many benefits when used as an ingredient in cosmetics.

    ◆Very safe.

    ◆Easy to use: readily soluble in water, highly heat-stable and useable over a wide pH range (5-8).
