Caprylhydroxamic Acid ("CHA") is a multifunctional ingredient used as a part of Hurdle Technology to create safe formulations in absence of traditional preservatives ("Alternative Preservation"). Caprylhydroxamic Acid is patented for use in cosmetics, toiletries, and pharmaceuticals by INOLEX, and has been used in cosmetics since 2008.
Alternative Preservation is a method of using multifunctional ingredients with antimicrobial properties as a preservation system instead of using traditional preservatives like parabens, isothiazolinones, or phenoxyethanol.
Traditional preservatives have come under increased scrutiny for their potentially adverse effects. As a result, consumers are looking for products that do not contain certain compounds with negative or harmful associations. For example, isothiazolinones have been associated with sensitization issues; formaldehyde donors release formaldehyde which is a known carcinogen; and phenoxyethanol, a replacement for Parabens, has been associated with irritation.
As consumers continue to engage on the topic, researching the products that they use and the ingredients within, the personal care industry must develop formulations free of traditional preservatives with robust efficacy to ensure both consumer safety and product protection against contaminants.
Alternative Preservation Systems, such as those offered by INOLEX, employ Hurdle Technology, which allows for the use of multifunctional components or aspects of the formulations as hurdles for microbes to collectively prevent contamination. These components and formulation factors can include membrane disruptors, organic acids, chelating agents and pH. A particular benefit of CHA is that it performs well at neutral pH where other organic acids are ineffective.
By using this strategy, formulators can use combinations of milder ingredients and other formulation factors instead of traditional preservatives that consumers are seeking to avoid. Success of this strategy also requires the use of Good Manufacturing Principles (GMP) in combination with the formulation approach to preservation.
