Geogard Ultra®

Sold by Arxada

Geogard Ultra® is a patented, synergistic blend consisting of Gluconolactone (polyhydroxy acid or PHA) and Sodium Benzoate. The synergy between these two ingredients, Gluconolactone and Sodium Benzoate, makes this preservative unique, allowing for its broad spectrum efficacy.

Organic acids often require a co-preservative or additional booster to provide an optimal performance, as they are too weak on their own. In this blend, the Gluconolactone works in conjunction with the sodium benzoate to perform as an efficient preservative booster that is also non-GMO. Geogard Ultra®’s Gluconolactone works by slowly releasing Gluconic Acid over time, which helps contribute to the preservation effect.

INCI Name: Gluconolactone (CAS: 90-80-2), Sodium Benzoate (CAS: 532-32-1) and Calcium Gluconate (CAS: 299-28-5)

Description

Geogard Ultra® is a synergistic, patented blend comprised of gluconolactone and sodium benzoate. What makes this preservative unique is the synergy between the two ingredients, allowing 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 together with the sodium benzoate to act as an efficient preservative booster that is also non-GMO. Geogard Ultra®’s gluconolactone works by slowly releasing gluconic acid over time, which helps contribute to the preservation.

Formulation Recommendations
  • Water soluble
  • Compatible with a wide variety of formulation ingredients as well as most types of cationic, nonionic and anionic systems
  • Can be used effectively over a pH range of 3 to 6 and can be added at both room and elevated temperatures
  • Soluble up to 4% in ambient water; it can be easily dispersed in glycols and alkyl sulfates
  • To maximise the pH stability of the final formulation, it may be necessary to employ use of a sodium citrate buffer and pH adjustment as described below:
    1. Dose the final product with the required level of Geogard Ultra® along with a 1.5x amount of sodium citrate. So, a 2% dose of Geogard Ultra® should be accompanied by 3% sodium citrate
    2. Mix thoroughly to ensure all solids have dissolved and adjust the pH of the formulation to 7.00-7.25 with 30% sodium hydroxide
    3. Finally, adjust the pH to desired final product pH (pH 5.4–5.5 is ideal) with dilute sodium hydroxide or citric acid solution

Efficacy

Microbiological Challenge Studies
Studies were run using different concentrations of Geogard Ultra® in various formulations to see efficacy against various bacteria and fungi. All samples were inoculated at the beginning of the study, sampled at 7, 14 and 28 days.

In these challenge studies, the bacterial pool consisted of S.aureus, P.aeruginosa and E.coli, and the fungal pool of C.albicans and A.brasiliensis.
