{snippet adszooleft} In today’s market, companies are seeking alternatives to traditional preservatives. NeoDefendTM is a preservative designed to meet those needs. Instead of a harsh, aggressive approach with bacteria and fungi, NeoDefendTM helps prevent product spoilage by utilizing less aggressive “Hurdle Technology” to create a more hostile environment within the formulation for microbes to overcome. NeoDefend’s potentiators help create such hurdles, helping to increase the self-preservation of formulations.
 
Derived from ingredients granted GRAS status (Generally Regarded As Safe), NeoDefend’s ingredients are accepted by ECOCERT as preservatives in certified organic cosmetics. Consisting of a blend of gluconolactone, sodium benzoate and calcium gluconate, it offers broad spectrum protection in cosmetic and personal care formulations.
 
A gluten-free fermented food starch derived from non genetically-modified corn via a fermentation process with non genetically-modified microorganisms, gluconolactone finds use in the food and cosmetic industry as a moisturizer, antioxidant and chelant. Considered a next generation AHA, Gluconolactone is a Polyhydroxy acid (PHA) that is found in its final state in bee’s honey. It is generally considered suitable for all skin types, including sensitive skin, and is non-irritating and antioxidant. Given their ability to condition and hydrate skin, Gluconolactone-containing formulations may even smooth skin texture and reduce the appearance of fine lines and wrinkles.
 
Sodium benzoate is a preservative with bacteriostatic and fungistatic properties under acidic conditions (pH should be 6 or below). Calcium gluconate is added at a very low level as an inert flow agent.

Formulating Information
  • NeoDefendTM is fully compatible with a wide variety of formulation ingredients as well as most types of cationic, nonionic and anionic systems.
  • NeoDefendTM can be used effectively over a wide pH range of 3 to 6.
  • Due to its heat stability, NeoDefendTM may be added to the water phase of formulations early in the compounding process.
  • Can be added at cool down, in the final phase of processing, although it should be pre-dissolved in a portion of the water prior to addition to the batch.
  • In some formulations, NeoDefendTM has been found to cause a pH drift downwards. In such a situation, sodium citrate or phosphate buffers can be used to raise the pH back up.
