INCI ADOPTED NAME
Caprylhydroxamic Acid (and) 1,2-Hexanediol (and) Propanediol
Spectrastat PHL* is a blend of multifunctional ingredients that allows formulators to use hurdle technology to create self-preserving formulations. As opposed to traditional methods of preservation, hurdle technology is a formulation approach whereby combinations of ingredients and other aspects of formulation are used along with good manufacturing principles. 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.
