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
