SpectrastatTM PHL is a blend of multifunctional ingredients that allows formulators to use hurdle technology to create self-preserving formulations. SpectrastatTM PHL 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. SpectrastatTM PHL is suitable for sensitive facial applications, where low irritation is required. A special benefit of SpectrastatTM PHL is that it performs superbly at neutral pH, a state where many other alternative preservation systems are ineffective. SpectrastatTM PHL is effective in typical personal care products such as creams, lotions, shower gels and makeup. It may be added to the water phase, at ambient or hot temperatures.
