Cosphaderm® Sodium LAAS (INCI: Sodium Levulinate, Sodium Anisate) is a 100% natural, water-soluble powder blend manufactured by Cosphatec. By combining the sodium salts of Levulinic Acid (from sugar cane) and p-Anisic Acid (from star anise), this blend provides a comprehensive, “all-in-one” natural preservation solution. It is designed for formulators who require a single, easy-to-dose raw material that delivers full-spectrum protection against bacteria, yeasts, and moulds without the need for synthetic additives.
Key Benefits and Performance
-
True Full-Spectrum Protection: The blend utilizes a “dual-salt” strategy to cover all five standard challenge test organisms.
-
Sodium Levulinate: Provides the primary antibacterial defense.
-
Sodium Anisate: Delivers powerful antifungal efficacy against yeasts and moulds.
-
-
Superior Water Solubility: As a blend of sodium salts rather than pure acids, it dissolves rapidly in the water phase. This significantly simplifies manufacturing compared to using individual crystalline organic acids.
- Masking: The gentle, characteristic scent of Sodium Anisate effectively masks “base” odors from other raw materials.
-
pH-Adjusting Capability: The blend can contribute to the stabilization and adjustment of the final formulation’s pH.
-
Clean Beauty Standard: 100% natural origin (ISO NOI 1.0), non-GMO, and fully COSMOS/ECOCERT compliant.
Formulation Guidelines
-
The “pH Activation” Rule: Although supplied as salts, these ingredients only become antimicrobially active when converted to their acid forms within the formulation. The final pH must be within the recommended range
-
Compatibility: Suitable for O/W, W/O, surfactant-based, water-based, and waterless (anhydrous) systems.
-
Boosting Strategies: For high-risk formulations or complex matrices, it can be combined with Cosphaderm® PA ECONAT (chelator) or Cosphaderm® GMCY (booster).
