Also known as Neodefend.

White powder composed of 75% gluconolactone (gluconic acid ester obtained by corn fermentation) and 25% sodium benzoate (sodium salt of benzoic acid, synthetic).

Geoguard Ultra is a synthetic product that mimics natural molecules. It is identical in every way to the natural version. Its manufacturing is ecological and its use is safe, provided that the dosage is respected. Using synthetic Geoguard Ultra is more environmentally friendly than manufacturing molecules directly from nature, as this would require large quantities of organic materials. This is a process that would not really be viable or possible, given the quantities used. For all these reasons, some still consider it a “natural” product. This is also why it is classified in the preservatives natural, despite its synthetic nature. The choice to use it or not remains personal :) At Âmes Fleurs, we consider that it is a preservative clean, safe, reliable, healthy for us and for the environment. Approved by Ecocert. Gluten and GMO free.

INCI : Glucoonolactone (and) Sodium Benzoate

Solubility: Soluble in water. This preservative tolerates heat well and it can take a long time to dissolve. 

pH: Effective in formulas containing water with a pH between 3.0 and 6.0.

*Face creams require a pH of 5. For eye creams, whose pH should ideally be 7, use instead Pentylene glycol.

Properties: Antifungal, antibacterial

Usage: Can be used alone as preservative. Must be added to the aqueous phase at the start of the recipe or during the cooling phase. If added during the cooling phase of an emulsion, dissolve the powder in water before adding it to the recipe.

Note that waterless formulas do not require preservative. However, you will benefit from using an antioxidant, such asvitamin E oil. This slows down the rancidity of fats, but is not a preservative.

Focus: From 0.75% to 2%

Uses: For any product containing an aqueous phase

We recommend avoiding infusions and favoring aloe gel (which already contains a preservative), distilled water and hydrosols. According to chemists, these are not stable, but we are herbalists, and we love hydrosols! These can be kept for a good year, or even longer. Which is rather stable for water. With hydrosols in an aqueous phase, an O/W emulsion can be kept, thanks to sodium benzoate, for around a year, which is very acceptable in our eyes. We prefer to make living products that last for a few months rather than dead products that remain stable for years!

WARNING: Keep out of reach of children. / Do not swallow or inhale and avoid contact with eyes. / Respect the recommended dosage. / Always do an allergy test on the forearm (finished product test).
