INCI ADOPTED NAME
Caprylhydroxamic Acid (and) Caprylyl Glycol (and) Propanediol
Spectrastat OL* is a blend of multifunctional ingredients that allows formulators to use hurdle technology to create self-preserving formulations and has broad spectrum preservation effects at pH 4 – 8 in an easy-to-use liquid form. 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 OL is especially useful in cold-process applications, such as toiletries and wet wipes. It is completely liquid, homogeneous, and pumpable even at low temperatures.
Spectrastat OL includes caprylyl glycol, light, medium spreading emollients, that also have antimicrobial properties, caprylhydroxamic acid (CHA), a chelating agent, and propanediol.
By using Spectrastat OL 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 OL is that it performs superbly at neutral pH, a state where many other alternative preservation systems are ineffective.
