Tristat® Eco

TRIstat® ECO is a sophisticated blend that pairs the classic antimicrobial power of Benzyl Alcohol with the specialized efficacy of fatty acid glyceryl monoesters. This “multi-hurdle” approach ensures that the formulation is protected against a wide array of contaminants while maintaining a clean, natural profile.

Key Benefit: Delivers robust, globally compliant protection across diverse pH conditions, making it suitable for complex natural formulations.

Performance & Synergistic Strategy

  • Broad-Spectrum Protection: The combination of an aromatic alcohol and medium-chain monoglycerides provides a complete defense against Gram-positive bacteria, Gram-negative bacteria, yeast, and mould.
  • Membrane Disruption: The glyceryl monoesters (Glyceryl Caprylate and Undecylenate) act as “boosters” by destabilizing microbial cell membranes, allowing the Benzyl Alcohol to work more effectively at lower concentrations.
  • pH Versatility: Unlike pure organic acid preservatives that fail above pH 5.5, this system remains effective across a wider range of formulation environments.
