Geogard 221 Preservative

Geogard® 221 is a versatile broad-spectrum preservation system featuring a combination of Dehydroacetic Acid and Benzyl Alcohol. Designed for use in a diverse range of cosmetic and personal care formulations, it provides effective protection against bacteria, yeast and mould while offering reliable performance at low usage levels. Its light colour and low odour profile make it particularly useful in formulations where minimizing the preservative's impact on the appearance and fragrance of the finished product is important.

Suitable for a wide variety of rinse-off and leave-on applications, Geogard 221 can be used in creams, lotions, shampoos, conditioners, facial cleansers, toners, gels, liquid soaps and other water-based and emulsion-based formulations. Its broad formulation compatibility allows it to be incorporated into many different types of personal care products, including nonionic, anionic and cationic systems. Geogard 221 is recommended for formulations within a pH range of 2–7 and should be incorporated at temperatures below 45°C for best results.

Geogard 221 is Soil Association approved and permitted for use in COSMOS and ECOCERT final formulations, making it a useful preservation option for formulators developing products to recognized natural and organic cosmetic standards. It is also Non-GMO, vegan, paraben-free and free from formaldehyde-releasing preservatives, providing formulators with a flexible preservation system for a wide variety of modern cosmetic and personal care products.
