A combination of a naturally occurring food additive glucono delta lactone (derived from corn) and a food-grade preservative sodium benzoate (the sodium salt of benzoic acid) along with a trace amount of calcium gluconate as a processing agent.

This preservative is excellent for challenging formulations that tend to separate after time and are affected by chemical reactions. It offers broad-spectrum preservation, is compatible with surfactants, can be added before cool down and will not affect the texture or viscosity of a formulation. 

Geogard Ultra™ is accepted by ECOCERT as a preservative in certified organic cosmetics.

Geogard Ultra™ not only provides effective protection against product spoilage, but it can also increase the skin moisturising capacity of the formulation.

This product is intended for external use only.

Best Preservitive!

I use this to preserve all of my product that don't have Vitamin C in them. I have also done efficacy testing and found this to be very effective against bacteria, mold and yeast when use at 1%.
