NeoDefendTM

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 situations, sodium citrate or phosphate buffers can be used to stabilize the pH.
There is some concern that  Sodium Benzoate, one of the ingredients in NeoDefend, in combination with L-Ascorbic Acid in products can form Benzene, a known human carcinogen. The presence of ascorbic acid and benzoates alone does not lead to the formation of benzene.  Certain additional conditions are required for trace levels of benzene to form, including heat, ultraviolet light and metallic ions in the mixture. Therefore, a product containing ascorbic acid and benzoates will not necessarily contain any detectable levels of benzene.  The use of EDTA, which chelates metallic ions can therefore be of assistance in the inhibition of benzene formation.  However, because of the potential to form benzene, we recommend that NeoDefend not be used combination with L-Ascorbic Acid (Vitamin C).  Citric Acid is not thought to induce significant benzene production in combination with Benzoic Acid, but some evidence suggests that in the presence of ascorbic acid and benzoic acid, citric acid may accelerate the production of benzene.  Therefore, the use of NeoDefend and L-Ascorbic Acid and Citric Acid in the same cosmetic formulations should be avoided.

Our Customers Say...
Lotioncrafter is my favorite place with cosmetic ingredients. I’ve been a regular customer since 2006. Great quality, service, always fast shipping. Thank you Lotioncrafter!
Barbara

I am impressed. I placed an order on Monday morning, by that afternoon I already had a UPS confirmation for pick up in my emailbox! Lotioncrafter not only offers the most amazing ingredients that makes any formulator's mouth water but it has fast shipping to boot. I am glad I discovered this company.
LeKenda

I have to admit, the products are well packaged, but the adorableness of the little containers makes me go, "awwww," when I start to formulate.

All cute aside, I love LotionCrafter. I can get products here I have a hard time sourcing at rates I'm willing to pay. I don't want to buy huge amounts of anything when I'm making initial formulations. I want to use small amounts to decide if something should be in my line. I can go small, or huge and that makes me feel confident that I can source what I need in amounts I can purchase.

I can get silicones here I can't find anywhere else and I've made my own primer that's head and shoulders above anything else I've ever purchased for any amount of money.

I am in love and I have large orders planned over the next few months. Thank you.
Nancy Liedel, (Makeup by Nancy)

Items all arrived on time and very well packaged. It looks like Lotioncrafter took the time to wrap and label each item carefully, legibly and to protect from moisture and light. They even returned part of my shipping cost to just cover the actual incurred shipping cost. Nice and honest seller. Will definitely return to shop for some more stuff. Thank you!
Ed

I'm always amazed by the quality and service. I placed an order late Friday and received it on Monday! Superior service as well as products! Thank you!
