The Science Behind

This preservative system employs traditional preservation alongside the Hurdle Technology approach, utilizing a combination of a traditional preservative with multifunctional ingredients to create a hostile environment for microbial growth.

Phenostat™ includes the following multifunctional components to create a complete broad spectrum preservation system:

  • Caprylhydroxamic Acid: 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.
  • Phenoxyethanol: A traditional preservative
  • Methylpropanediol: A carrier for ease of formulation
