EPSAN® PLUS

Natural, broad spectrum and water soluble preservative system

INCI name

Aqua, p-Anisic Acid, Polyglycerin-10, Polylysine, Coco-Glucoside

EPSAN® Plus is a new versatile and 100% plant-derived preservative system derived from p-anisic acid and polylysine that has an antimicrobial effect against yeasts, fungi, gram + and – bacteria, making it suitable for applications in the cosmetic industry and oral care.

This synergistic blend binds to polysaccharides (murein or bacterial mucopeptide) present in the cell walls of bacteria and denatures them, causing damage and inducing the micro-organisms to autolysis.

EPSAN® Plus is effective in a pH range comprised between 4.5 – 7.5, it is almost odourless and does not affect viscosity of the formula. Moreover, it has high thermal stability which makes it suitable to be treated with raw materials for sterilization or dispersed before emulsification.

It is advisable to not use substances obtained through a fermentation process in formulas containing EPSAN® Plus as preservative system (e.g. Xanthan Gum), because Polylysine binds to polysaccharides and denatures them.
