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.

Gluconolactone and sodium benzoate in powder form.

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.

Some may be sensitive to sodium benzoate. Avoid use of this preservative if you are, or do a skin patch test first.

This natural product is for external use only. Please exercise caution and do not ingest or take internally. Store away from children, animals, sunlight and heat. If pregnant or breastfeeding, please consult with your medical care-giver before use.

Struggling

I am very frustrated. I used to use Geogard 221 but didn't like the smell in my products. So bought Geogard Ultra. First time added to my water phase but it made small crystals in my products after it all has cooled down. Now I have dissolved it in a little water from my water phase and added it during the blending phase. It has immediately changed the colour and the consistency of the cream. I am very frustrated now and angry because this is quite a pricy product and now I am stuck with 250 g of it and don't want to use it anymore. It worked better in a cold process for my Hyaluronic acid serum.
Hope there is something that I am not seeing or doing

Geogard Ultra / Geogard

Hi Juliette
I wanted to order Geogard , but you are out of stock, so i have ordered 2 samples of the Geogard Ultra. I am very new to formulating so don't understand all the ins and outs. I make a face cream that has a hydrosol and carrier oil. Am I to add the ultra in the hydrosol before or after the heating phase and before I add the oil to the hydrosol? I am used to Geogard right at the end of the formulating process.
Thank you

Hi Renee, I reserve a little bit from the water phase and use that to dissolve the Geogard then add at the end. Geogard does benefit from a buffer system with sodium citrate so remember to include that as well. It's just a matter of adding the sodium citrate to the Geogard solution and adjusting the pH. There are instructions for this on the product page

Hi there. I want to buy geoguard 221, but i want to know if i can make the powder into a solution for easier future use and also if i use the powder do i need the sodium citrate?

Hi Ruanda! I haven't done this myself but I don't see any reason why you shouldn't be able to make up a stock solution of the Ultra for later use. I would do the sodium citrate dosing now, rather than later, as this way you will be able to keep track of the pH better.
