Evicide® levulinate S eco (INCI: Aqua, Sodium Levulinate, Potassium Sorbate) is a 100% natural, liquid preservative blend . Presented as a clear, pale-yellow liquid, this blend is a highly effective “hurdle” system that pairs two complementary organic acid salts. It is specifically designed for formulators who require robust, full-spectrum microbial protection within a completely natural and sustainable framework.
Key Benefits and Performance
-
Verified Broad-Spectrum Activity: This blend is rated “very good” against all four major organism categories: Gram-positive bacteria, Gram-negative bacteria, yeasts, and moulds.
-
Synergistic Duo: It leverages Sodium Levulinate for powerful antibacterial and anti-yeast action, while Potassium Sorbate provides targeted, superior defense against moulds.
-
High Formulation Flexibility: Unlike many natural preservatives, it has excellent water solubility and can be incorporated into the water phase at any stage—under simple stirring, heated, or added before homogenization.
-
Gentle for Sensitive Applications: Because of its balanced salt profile, it is a preferred choice for high-sensitivity categories like baby care, micellar waters, and wet wipes.
Formulation Guidelines
-
pH-Dependent Activation: The salts must convert in situ to their active free acid forms (Levulinic and Sorbic acid) to work. Optimal performance is achieved in a pH range of register to find out below
-
Dosage-pH Relationship: At the upper end of its effective pH range, a higher usage level is necessary to compensate for the lower proportion of undissociated acid.
