Cosphaderm® pAS natural (INCI: p-Anisic Acid) is a 100% plant-derived, multifunctional antimicrobial. Sourced from star anise (Illicium verum), this crystalline powder is a high-purity organic acid. Beyond its anti-fungal property, it provides a delicate, masking scent and acts as a secondary pH adjuster.
Key Benefits and Performance
-
Specialist Antifungal Power: It delivers exceptional protection against yeasts and moulds. It is specifically engineered to fill the “fungal gap” left by many other natural antibacterial agents.
-
The “Hurdle” Synergy: To achieve full-spectrum protection (ISO 11930 compliance), it is best paired with a strong antibacterial partner such as Cosphaderm® LA-T or Cosphaderm® GMCY
-
Fragrance & Masking: It possesses a very gentle, pleasant characteristic scent (reminiscent of hawthorn/anise). This makes it highly effective as a masking agent to cover the raw-material base odors of botanical extracts or proteins.
-
Secondary pH Adjustment: As an organic acid, it can contribute to the acidification and stabilization of the final formulation’s pH.
Formulation Guidelines
-
pH Dependent Like all organic acids, its antimicrobial efficacy is strictly pH-dependent. It must be used in formulations with a pH withint the recommended range to ensure the molecule remains in its active, undissociated form
