Geogard Ultra™ is a globally approved, synergistic, patent pending, multifunctional blend of Gluconolactone and Sodium Benzoate. Organic acids have good scientific properties such as fungicidal efficacy, good compatibility with other raw materials and acceptable regulatory/marketing status but they can be too weak on their own and need co-preservatives or preservative boosters. Gluconolactone has been found to be an efficient preservative booster that is also non-GMO.

Geogard Ultrais ideally positioned as a baby products’ preservative system thanks to its Ecocert and COSMOS accepted status, non-GMO approval and soil association approval, and the absence of controversial chemistries (no parabens, halogen, formaldehyde or phenoxyethanol).

Geogard Ultra™ is water soluble and is recommended for use at 0.75 – 2.0% and at a pH of between 3.0 and 6.5.


FormulaProtect™ is a new interactive, online application developed by Lonza that allows formulators to save time and easily identify preservatives that best suit their specific needs. By simply selecting specific formulation criteria such as pH, required spectrum, formulation type, regulatory and organizational approvals, amongst other criteria, the user will be presented with a selection of recommended preservative options along with detailed information on each of them.

This tool will help provide guidance for the preservatives that meet formulator’s marketing needs and that provide the efficacy required throughout the lifetime of the cosmetic product.

You can visit the tool through your web browser by going to the Lonza FormulaProtect™ website.
