EPSAN® PLUS is a patent-pending preservation platform that leverages the synergy between an aromatic acid and a fermented homopolymer. By combining p-Anisic Acid (derived from anise) with Polylysine (produced via bacterial fermentation), the system overcomes the individual limitations of each active to provide robust defense against bacteria, yeasts, and molds.
Key Benefit: A “Synergistic Bio-Defense” where p-Anisic acid compensates for Polylysine’s sensitivity to acidic polysaccharides and metal ions, ensuring stable antimicrobial activity in complex natural formulas.
Performance & Synergistic Mechanism
-
Broad-Spectrum: Polylysine provides a powerful cationic “punch” against Gram-positive/negative bacteria, while p-Anisic acid delivers established, high-performance antifungal properties.
-
Environmental Resilience: The inclusion of p-Anisic acid protects the system’s efficacy in the presence of phosphates, copper ions, and acidic polysaccharides, which typically inhibit Polylysine when used alone.
-
Solubilized Convenience: The use of Polyglycerin-10 and Coco-Glucoside as carriers ensures the aromatic acid remains stable and clear in a water-soluble liquid format.
Formulation & Compatibility Guidelines
Because Polylysine is a cationic polymer, its interaction with common natural thickeners is the most critical factor for success.
