The 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.

Spectrastat™ PHL 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.
  • 1,2–Hexanediol: A skin conditioning agent and humectant that prevents the growth of bacteria in formulation. It has a short carbon chain length which makes it ultra-mild on skin.
  • Propanediol: A 100% natural humectant that acts as a carrier for ease of formulation.
