Product Details:
- Sodium Benzoate Preservative
- Sodium Benzoate is a food grade preservative that is generally regarded as safe (GRAS) worldwide
- Sodium Benzoate is soluble in water where it converts to benzoic acid
- Sodium Benzoate is bacteriostatic and fungistatic when used in acidic conditions where the pH of your product is below 6.0.
- Sodium Benzoate is not a broad spectrum preservative for cosmetic use and as such should be combined with other preservatives such as Potassium Sorbate
Advantages to using Sodium Benzoate are:
- Sodium Benzoate is effective in products with a pH of 6.0 or below
- Sodium Benzoate is a water-soluble preservative product
Special Notes:
Studies on internal food product usage have shown that Sodium Benzoate, when combined with Vitamin C, can form small levels of Benzene, a known carcinogen. While these studies were not done on its use as a preservative for personal care products, and Sodium Benzoate is considered safe for use by Health Canada and the FDA, if you are at all concerned we recommend not using this preservative in conjunction with Vitamin C (ascorbic acid)
