Science Behind

This alternative preservation component contributes to creating a hostile environment for microbial growth as part of a Hurdle Technology approach. Zeastat™ can be a complete system for certain formulations or a component of your broad spectrum customized system.

  • Caprylhydroxamic Acid: A multifunctional component. It is a 100% natural organic acid and chelating agent that prevents the growth of yeast and mold in formulation. Unlike most organic acids used in preservation, caprylhydroxamic acid remains undissociated at neutral pH.
  • Propanediol: A carrier for ease of formulation.
