Science Behind

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

Aromastat™ 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.
  • Phenethyl alcohol: A carrier for ease of formulation that prevents the growth of bacteria in formulation
  • Glycerin: A 100% natural humectant that acts as a carrier for ease of formulation. Glycerin also reduces water activity for preservation effects.
