Evicide® levulinate B (INCI: Aqua, Sodium Levulinate, Sodium Benzoate) is a cost-effective,preservative blend. It combines the skin-conditioning and antibacterial power of plant-derived Sodium Levulinate with the globally recognized antifungal strength of Sodium Benzoate. This synergistic blend is designed to provide robust full-spectrum protection while remaining mild enough for sensitive skin and baby care applications.
Key Benefits and Performance
-
Synergistic Protection: The combination of two proven organic acid salts provides a highly effective barrier against bacteria, yeast, and mould.
-
Specialized for Wet Wipes: It is positioned as a “simple solution” for wet wipe preservation. Wipes are notoriously difficult to preserve due to the large surface area of the fabric; this blend is engineered to remain active and stable within the wipe substrate.
-
Cost-Effective Efficiency: By using nature-identical Sodium Benzoate, it offers a more budget-friendly alternative to blends using rarer organic acids, without compromising on microbial safety.
-
Skin Conditioning: Sodium Levulinate is a multifunctional active that improves skin moisture and softness. This makes the preservative system an active part of the skincare routine.
-
Easy Handling: As a fully water-soluble liquid, it eliminates the need for heating or complex dissolution steps required by powder preservatives.
Formulation Guidelines
-
The “pH Rule”: Like all organic acid systems, its efficacy is strictly pH-dependent. For the preservatives to be active, the final formulation must be adjusted to pH register to find out below
-
Emulsion Boosting: In complex O/W emulsions, the addition of a boosting agent (like Evicide® GMCY / Glyceryl Caprylate) is recommended to ensure the oil phase is equally protected.
