Polylysine 25% solution is a natural polymer of L-Lysine, an essential amino acid produced by fermentation of bacteria. It can be used alone or in combination with other preservatives. It is not compatible with anionic surfactants. Effective pH 5-8.

E-POLYLYSINE 25% SOLUTION is Amino acid-structured preservative. As an ingredient manufactured from natural substances using our biotechnology. POLYLYSINE is a straight chain polyamino acid that connects 25 to 35 L-lysine residues,characterized by a peptide bond between the epsilon amino group and the carboxyl group in L-lysine, a kind of essential amino acid.

Cosphaderm® Hexiol is a pure, transparent and colorless glycol. Two vicinal OH-groups and a short carbon chain allow unlimited water-solubility. This property is strongly relevant to its most common cosmetic use as a moisturizer and humectant for both skin care and hair care formulations. Static light scattering experiments have shown that Cosphaderm® Hexiol can also be used to stabilize o/w emulsions by droplet size reduction. Another core property of 1,2-hexanediol is its pH-independent antimicrobial activity. It further shows remarkable synergistic effects in combination with other antimicrobial substances, making it possible to minimize the total amount of combined preserving agents.

Cosphagard® Exact is a blend of the preservative Phenoxyethanol with Ethylhexylglycerin. It displays a broad antimicrobial efficacy spectrum against bacteria, yeasts and molds. The clear fluid blend is pH-independent and temperature-stable.
