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.
Key Properties Ingredients: Sodium Benzoate Form: Water-soluble crystalline powder Suitable For: Food and Cosmetic Use Food Grade Function: Preservative ingredient for acidic water-based formulas Recommended Usage Rate: 0.5-3% Most Effective At: Low pH, around pH 3 Vegan Halal Certified Kosher Certified GMO-Free What It's Used For Preserving acidic water-based cosmetic products Supporting preservation in DIY skincare and personal care formulas Combining with potassium sorbate in suitable systems Adding to formulations where a water-soluble preservative ingredient is needed Who It's For This Product Is For: DIY formulators making water-based products Makers working with acidic formulas Users building preservative systems with more than one ingredient This Product Is Not For: Oil-only products Anyone expecting a complete broad-spectrum preservative on its own High-pH formulations without proper adjustment How To Use Dissolve at 0.5-3% in water.
Use in suitable water-based formulations with an appropriately low pH. Combine with potassium sorbate where your formulation calls for broader support. Adjust pH with citric acid where needed. Safety Instructions Some people may be sensitive to sodium benzoate, so patch test the finished diluted product first.
Avoid inhaling loose powder. Keep well sealed and store away from children, animals, moisture, sunlight, and heat. Use clean, dry utensils when handling. FAQs Q: Can sodium benzoate be used on its own? A: It can be used on its own, but it is not a broad-spectrum preservative by itself, so it is often combined with potassium sorbate for better overall support.
Q: Why does pH matter? A: Sodium benzoate works best in acidic formulations, with its strongest performance around pH 3.
