ECOCERT approved, Geogard Ultra is a multifunctional preservative, naturally derived and globally accepted. It contains no parabens or formaldehyde releasers, and it utilizes benzoate - an organic acid - as the main preservative.
We love it because it is easy to work with in powder form, and importantly has no scent of its own, making it great for products where you can't hide the smell of a preservative. It also works in formulas with a low pH.

How to use geogard ultra
Usage: 1-2%, diluted in the water phase.
Optimum pH: 3-7
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 a 30% sodium hydroxide solution (an alternative to sodium hydroxide could be L-arginine).
3. Finally, adjust the pH to desired final product pH (pH 5.4–5.5 is ideal) with dilute citric acid solution
Keep in mind that salts (sodium) are electrolytes and can interact with certain emulsifiers. Check that your emulsifier has an electrolyte tolerance.
Geogard ultra warnings
Some may be sensitive to sodium benzoate. Avoid use of this preservative if you are, or do a skin patch test first.
