Sodium Benzoate - 500G

Features

Description

Essentially Natural Sodium Benzoate is a water-soluble crystalline preservative ingredient used in water-containing cosmetic formulations. It is most effective in acidic products and is commonly combined with potassium sorbate or other compatible preservatives to broaden preservation support. It is particularly useful in toners, gels, cleansers, lotions and surfactant-based products formulated at a suitably low pH.

Sodium Benzoate is not usually considered a complete broad-spectrum preservation system when used alone. Why we love it: Sodium Benzoate is a practical option for makers who understand pH-controlled formulation and want a readily soluble preservative ingredient. Its compatibility with combined preservation systems makes it useful across many acidic water-based products.

Key Properties INCI Name: Sodium Benzoate Ingredient Type: Preservative Form: Crystalline powder Solubility: Water soluble Typical Usage Rate: 0.5-3%, subject to the intended application and local regulations Best Efficacy pH: Around pH 3 Halal Certified Kosher Certified Vegan Friendly GMO-Free Suitable For: Acidic Water-Based Cosmetic Formulations Food Safety Note: Food safe, not confirmed as food grade certified Storage: Store tightly sealed away from moisture, heat and direct sunlight What It's Used For Preservation support in water-based cosmetics Acidic toners, gels, lotions and cleansers Combined preservative systems Water-phase preservation in emulsions Surfactant-based rinse-off formulations Products where the final pH can be accurately measured and controlled Who It's For This Product Is For: Formulators making water-containing products that require preservation Makers who can accurately measure and adjust pH Combined preservative systems using compatible ingredients Acidic cosmetic formulations This Product Is Not For: Anhydrous products with no water phase High-pH formulations Use as a guaranteed broad-spectrum preservative on its own Makers unable to test final product pH Formulas that will not undergo appropriate stability and preservation testing How To Use As a Water-Phase Preservative: Dissolve thoroughly in the water phase before combining with the remaining ingredients.

As a Combined System: Use with compatible preservatives such as potassium sorbate where suitable for the formulation. As a pH-Dependent Preservative: Measure and adjust the final product pH to the range required by the complete preservation system. Processing Tip: Confirm that the powder has dissolved fully before completing the formulation.

Testing Tip: Conduct stability and microbial challenge testing on products intended for sale. Safety Instructions For cosmetic formulation use only unless the intended alternative application is properly assessed Avoid inhaling airborne powder Avoid contact with eyes Wear suitable eye protection when handling larger quantities Do not exceed applicable regulatory limits Keep tightly sealed and dry Keep out of reach of children and pets Test the preservation system in the finished formulation before use or sale FAQs Q: Can Sodium Benzoate be used on its own?

A: It can provide preservation support, but it is not usually considered broad-spectrum by itself and is commonly combined with other compatible preservatives. Q: Why is pH important when using Sodium Benzoate? A: Its preservative activity depends strongly on acidity. It becomes less effective as the formulation pH increases.

Q: Does Sodium Benzoate dissolve in oil? A: No. It should be dissolved in the water phase of a formulation. Q: Can it be added to an existing unpreserved product? A: Simply adding it to a finished product does not guarantee adequate preservation. The pH, concentration, compatibility and full preservative system must be assessed.

Q: Is preservation testing still necessary? A: Yes. The completed formula should be tested because preservative performance depends on the entire product composition and manufacturing process.
