INCI ADOPTED NAME
Caprylhydroxamic Acid (and) 1,2-Hexanediol (and) Propanediol
Spectrastat™ PHL* is a broad spectrum preservation effect at pH 4 – 8 with high water solubility and formulation clarity; ideal for sensitive skin applications (66% biobased content). Spectrastat™ PHL is It is especially useful in high water, cold-process applications: e.g. toners, surfactant systems, and wet wipes. It is completely liquid, homogeneous, and pumpable even at low temperatures. Spectrastat™ PHL is suitable for sensitive facial applications, where low irritation is required. Spectrastat™ PHL includes 1,2-hexanediol, light, medium spreading emollient, that also have antimicrobial properties, caprylhydroxamic acid (CHA), a chelating agent, and propanediol.
By using Spectrastat™ PHL in the practice of hurdle technology, formulations that pass challenge tests can be created without the inclusion of traditional preservatives such as for example, parabens, isothiazolinones, and formaldehyde donors. These traditional preservatives are currently seen as undesirable by consumers. A special benefit of Spectrastat™ PHL is that it performs superbly at neutral pH, a state where many other alternative preservation systems are ineffective.
