INCI ADOPTED NAME
caprylhydroxamic acid (and) benzyl alcohol (and) glycerin
Benzostat is a blend of multifunctional ingredients that allows formulators to use hurdle technology to create paraben-free 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. Benzostat includes benzyl alcohol, an aromatic alcohol that also has antimicrobial properties, caprylhydroxamic acid (CHA), a chelating agent, and glycerin.
By using Benzostat 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 Benzostat is that it performs superbly at neutral pH, a state where many other alternative preservation systems are ineffective.
