Natural active ingredient for cosmetics
Epsilon Polylysine, which is a natural antimicrobial agent for preservation and bacteria inhibition. It is produced by bio fermenttechnology, can inhibit Gram+ ,Gram, fungi, virus etc. It is colorless,
tasteless, water soluble and thermal stability. It can be active both in alkalinity or acidity condition.
Polylysine consists as a small natural homo-polymer (25-30 L-lysine residues) of the essential amino acid, L-lysine so it is high safe for human body. Advantage1. Broad antibacterial spectrum: it has obvious inhibition to gram-positive bacteria and gram-negative bacteria, yeast, mould, virus and many other micro-organisms.
2. Good thermal stability: below high temperature(80oC for 60 min,100oC for 30 min and 120oC for 20 min. Polylysine does not decompose, nor experience inactivation, and is suitable for cooked food.
3. Good water-solubility: Polylysine has good water-solubility, Polylysine spreads evenly in food; colorless, odorless and natural, does not affect overall food flavor.
4. Wide pH range: broad anti-bacterial spectrum (pH 2 to 9), to supplement the weakness with most common preservatives; poor effects in neutral and alkaline conditions.
5. Strong blends: it have a synergistic effect when blending with Potassium Sorbate, Citric acid, Malic Acid, Glycine and Nisin.
6. Safe for human consumption: after eating, Polylysine does not accumulated inside the human body. It partly breaks down into L-lysine, an essential amino acid for human health. L –lysine is non-toxic, and known as the "pharmaceutical & nutrient preservative".
7. Health function: Recent studies show that ε-Polylysine can inhibit the enzyme activity and the fat absorption in the small intestine ester, has curative effect against, with obesity.
