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 maximize 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
Recommended Use Level
0.75–2.0%
INCI - Gluconolactone (and) Sodium Benzoate
