Nautica Geogard Ultra - ECOCERT is a naturally derived multifunctional preservative in powder form, used to help protect cosmetic formulations that contain water-soluble ingredients. It is widely used in creams, lotions, shampoos, and other water-based or water-containing products where dependable preservation is essential. Because it has no scent of its own and works well in lower pH systems, it is especially useful in products where you do not want the preservative to interfere with the final fragrance profile. This is a cosmetic formulation ingredient rather than a finished product.

♡ Why we love it: Geogard Ultra is practical, versatile, and refreshingly easy to work with. The powder format makes it simple to handle, and the lack of scent is a real advantage when you want your fragrance or essential oil blend to stay centre stage.

Faqs

Q: Why do formulators like Geogard Ultra in scented products?
A: It has no scent of its own, so it is useful in formulas where you do not want the preservative to alter the final fragrance.

Q: Can I use Geogard Ultra in oil-only balms?
A: It is mainly suited to products with water-soluble ingredients, so it is not usually the right choice for fully anhydrous oil-only formulas.
