Description
The product is Geogard Ultra Ecocert approved, which means it is a multifunctional preservative that is naturally derived and globally accepted. It contains no parabens or formaldehyde releasers, and utilizes benzoate - an organic acid - as the main preservative. The product 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. The product also works in formulas with a low pH. The ingredients are gluconolactone and sodium benzoate in powder form. The usage is 1-2%, diluted in the water phase. The optimum pH is 3-7, and it may be necessary to employ use of a sodium citrate buffer and pH adjustment. The product is vegan friendly, not tested on animals, and certified cosmetic grade.

HOW TO USEGEOGARD 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 citrate2. 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 5.45.5 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.
FOR YOUR SAFETY
Some may be sensitive to sodium benzoate. Avoid use of this preservative if you are, or do a skin patch test first.
