Geogard Ultra® is a synergistic and patented
blend comprised of gluconolactone and sodium benzoate. Aside from its proven broad spectrum
activity, wide range of global regulatory approvals and broad formulation
compatibility, it also contributes an added skin moisturisation benefit and has
conformance with ECOCERT/COSMOS, NATRUE and the Soil Association.
What makes this preservative unique is the
synergy between the two ingredients which allows for its broad spectrum
efficacy. Typically, organic acids on their own are too weak and often require
a co-preservative or booster in order to perform optimally. The gluconolactone
in this blend works in conjunction with the sodium benzoate to act as an
efficient preservative booster, slowly releasing gluconic acid over time
thereby contributing to the broader preservation effect.
