Nat Defence

NEW

Previously called Geogard Ultra® (The only change is the name of this product)
Nat Defence is a natural preservative comprised of a combination of a naturally occurring food additives, glucono delta lactone, derived from corn, and a food grade preservative sodium benzoate, the sodium salt of benzoic acid, along with a trace amount of calcium gluconate as a processing agent. This is the solution for those challenging formulas in which you wish to change the preservation system to an efficacious natural preservative.

Nat Defence is an effective broad spectrum preservative (biocide) which can be included in organic products and is effective within a pH range of 3.0 - 6.5.   (However, we found the best efficacy with a narrower pH range of 4 - 5.5.)  There are also a few additional benefits - you can add it to the water phase whilst it is still quite hot (giving better control of the emulsion), and also test the pH at the same time, it is GRAS (generally regarded as safe) and is a proven moisturiser - another bonus!

With its multi-functionality, Nat Defence can be used in a wide range of cosmetic products including Shampoo and Hair Care Products, Lotions and Creams and Bath and Body Cleansing Gels.  In most formulations, testing showed an effective dosage rate of 1.0 - 1.5% of batch weight was suitable.

Suitable for:

  • Hair care
  • Hand cream
  • Moisturisers and Lotions
  • Facial moisturiser
  • Body wash
  • Facial cleanser
  • Styling gel
  • Anti-aging
  • Eye cream
  • Deodorant
  • Foot moisturiser

Cosmetic products should undergo microbial testing to ensure the efficacy of any preservative system.

Suitable for a pH of 3 - 6.5 ( we recommend aiming for mid range for this preservative)
