Geogard Ultra®

Geogard® Ultra is a globally recognized, patented preservative system that utilizes a synergistic blend of a polyhydroxy acid (PHA) and an organic acid salt. While the Gluconolactone acts as an efficient efficacy booster for the Sodium Benzoate, it simultaneously functions as a high-performance humectant. Clinical testing has proven that it provides greater moisturizing effects compared to 2% Glycerin.
