Frequently Asked Questions
What is sodium benzoate used for?
Sodium benzoate (CAS 532-32-1), the sodium salt of benzoic acid, is used as a preservative for foods, beverages, and water-based products at acidic pH, and as a corrosion (rust and mildew) inhibitor. It also serves as a chemical intermediate, including in dye manufacture, and as a nucleating agent for polyolefins.
Are baking soda and sodium benzoate the same?
No. Baking soda is sodium bicarbonate (NaHCO3), an alkali salt used for leavening and neutralization. Sodium benzoate (C7H5NaO2) is the sodium salt of benzoic acid, used as a preservative and corrosion inhibitor. They are distinct chemicals with different CAS numbers and functions.
Is sodium benzoate the same as table salt?
No. Table salt is sodium chloride (NaCl). Sodium benzoate is the sodium salt of benzoic acid (C7H5NaO2, CAS 532-32-1); both contain sodium, but they are chemically different compounds with different uses. Sodium benzoate functions as a preservative, not a seasoning.
What is sodium benzoate made from?
Sodium benzoate is produced by neutralizing benzoic acid with a sodium source such as sodium hydroxide or sodium bicarbonate, yielding the sodium salt C7H5NaO2. It is supplied as a powder. See the SDS and CoA for grade and specification details.
What is the cost of sodium benzoate in bulk?
Bulk pricing depends on grade, packaging, and volume. We supply sodium benzoate powder in industrial quantities with CoA and SDS per lot; request a bulk quote for current pricing and lead time.
What is the REACH and TSCA regulatory status of Sodium Benzoate (Benzoate of Soda)?
Sodium Benzoate (Benzoate of Soda) (CAS 532-32-1) is subject to U.S. TSCA Inventory requirements; supplying it into the EU requires valid REACH registration ((EC) No 1907/2006). RawSource cannot verify a third-party supplier's registrations — buyers should require documented TSCA and REACH compliance for their jurisdiction and volume (EC 208-534-8).
