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™ E 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.
- Ethylhexylglycerin: A skin conditioning agent that prevents the growth of bacteria in formulation
- Methylpropanediol: A carrier for ease of formulation
