CFI Sodium Benzoate - Food Grade is a water-soluble preservative ingredient used mainly in water-based formulations, especially where the final pH is low. It is commonly used alongside potassium sorbate to improve preservation support in DIY cosmetic products. This is a formulation ingredient, not a complete broad-spectrum preservative on its own and not a finished product. It works best in acidic systems and is activated in water as it converts to benzoic acid.
♡ Why we love it: Sodium benzoate is one of those practical preservation-support ingredients that helps formulators build smarter, more stable water-based products. It is especially useful when paired correctly and used within the right pH range.

potassium sorbate for better overall support.
