NeoDefend 1oz

Carey Gajadhar — Tue, 16 Feb 2021 17:08:00 +0000

In today’s market, companies are seeking alternatives to traditional preservatives. NeoDefend^TM is a preservative designed to meet those needs. Instead of a harsh, aggressive approach with bacteria and fungi, NeoDefend^TM 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 starch derived from non genetically-modified corn via a fermentation process with non genetically-modified microorganisms, gluconolactone finds use in the 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.

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. 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.

INCI: Gluconolactone (and) Sodium Benzoate

NeoDefend^TM is fully compatible with a wide variety of formulation ingredients as well as most types of cationic, nonionic and anionic systems.
NeoDefend^TM can be used effectively over a wide pH range of 3 to 6.
Due to its heat stability, NeoDefend^TM 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 may need to be pre-dissolved in a portion of the water prior to addition to the batch depending on lotion consistency.
In some formulations, NeoDefend^TM has been found to cause a pH drift downwards. In such situations, sodium citrate or phosphate buffers can be used to stabilize the pH.

Recommended Use Levels: 0.75% – 1.5%, up to 2%
Appearance: Free flowing, white powder
Solubility: Soluble in water, propylene glycol, glycerin and mineral oil
Shelf life: Up to 3 years when stored in the sealed original packaging under normal temperature conditions, away from moisture.

Germall Plus Liquid is used in lotions, conditioners, shampoos, creams, body washes and body sprays along with other cosmetic formulations. Liquid Germall Plus is a water soluble preservative that is very effective at preventing the growth of gram positive and gram negative bacteria, molds, fungus, yeasts and commonly found organisms. Liquid germal plus works well at inhibiting the growth of these organisms at extremely low concentrations and because of this is considered very cost effective. It works well with most cosmetic ingredients, has no known inactivating counterpart ingredients and can be used in most surfactant formulations. The use level amounts is .1% – .5% of total weight formulation. It is also soluble in cationic, anionic and nonionic water soluble formulation. It should be added in a recipe when the mixture has cooled down to at least 50 C or below. INCI: Propylene Glycol (and) Diazolidinyl Urea (and) Iodopropynyl Butylcarbamate.

Optiphen Plus is a paraben- and formaldehyde-free preservative system that is ideal for products with a lower pH systems. Optiphen Plus is an ISP patent-pending liquid preservative formulation featuring an innovative blend of phenoxyethanol, sorbic acid and an emollient base that is ideal for slightly acidic personal care products requiring broad spectrum protection. The combination of all three ingredients offers effective protection against bacteria, yeast and mold growth while imparting emolliency. Optiphen Plus performs best in formulations below 6.0 pH. Depending on the formulation, Optiphen Plus has also been proven effective at pH levels above 6.0. This preservative is effective as a stand-alone system and functions well with other preservatives. Optiphen Plus has an extensive range of applications in aqueous and emulsion-type personal care formulations and is compatible with most raw materials in the personal care industry.

Optiphen Plus preservative should be used in cosmetic products at concentrations in the range of 0.75% to 1.5%. For the preservation of simplesurfactant products a dose of 0.5% might be sufficient. For the determination of optimum dosage they recommend a preservation test, as the efficacy of this preservative is highly influenced by the product matrix.

INCI: Phenoxyethanol (and) Caprylyl Glycol (and) Sorbic Acid.
