is a synergistic and patented blend comprised of gluconolactone and sodium benzoate. Aside from its proven broad spectrum activity, wide range of global regulatory approvals and broad formulation compatibility, it also contributes an added skin moisturisation benefit. The gluconolactone in this blend works in conjunction with the sodium benzoate to act as an efficient preservative booster, slowly releasing gluconic acid over time thereby contributing to the broader preservation effect.
