Geogard® 221 is a broad-spectrum preservative designed to protect water-based and emulsified personal care formulations against the growth of bacteria, yeast, and mould. Offering effective preservation at low usage rates, it is well suited for a wide range of rinse-off and leave-on products, including lotions, creams, shampoos, conditioners, facial cleansers, toners, gels, and liquid soaps.

Comprised of dehydroacetic acid and benzyl alcohol, Geogard® 221 is valued for its versatility, ease of use, and compatibility with many cosmetic ingredients. It is added during the cool-down phase and performs best in formulations with a final pH below 6, making pH adjustment and testing an important part of the formulation process.

Accepted for use in ECOCERT and COSMOS compliant formulations, Geogard® 221 is free from parabens and formaldehyde donors, making it a popular preservative choice for formulators developing naturally inspired personal care products. Whether you're creating handcrafted skincare or scaling up for commercial production, Geogard® 221 provides dependable broad-spectrum preservation to help maintain the quality and stability of your finished formulations.
