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.

Cosphaderm Magnolia Extract 98 is pure powdered extract of the bark of Magnolia Officinalis with a minimal content of 98% magnolol and honokiol in a ration of approx 1 to1. It inhibits the growth of bacteria and fungi pH independently.
