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 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 5.45.5 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.
