Frequently Asked Questions
What exactly is sodium diacetate?
Sodium diacetate (CAS 126-96-5) is a 1:1 molecular complex of sodium acetate and acetic acid (C4H7NaO4). It is used in food processing as an acidulant, buffer, and flavoring agent, as a mold and rope inhibitor in baked goods, and as a preservative for hay and silage.
Is sodium diacetate the same as vinegar?
No. Vinegar is a dilute aqueous solution of acetic acid, whereas sodium diacetate is a solid 1:1 complex of sodium acetate and acetic acid. It delivers acetic-acid functionality in dry, free-flowing form.
What is sodium diacetate used for in baked goods?
In baked goods it acts as a mold and rope inhibitor, and more broadly as an acidulant, buffer, and flavoring agent in food processing. It is also used as a preservative and sequestrant for hay and silage in animal feed.
What HS code applies to sodium diacetate?
Sodium diacetate is classified under HS 2915.29 (acetic acid and its salts, other). Confirm the destination-country tariff line and request the CoA and SDS with your order.
How is bulk sodium diacetate supplied?
It is supplied to food processors and feed producers as a free-flowing powder or granules in bags, drums, or totes. Request a bulk quote with your target volume and grade requirement.
What is the REACH and TSCA regulatory status of Sodium Diacetate?
Sodium Diacetate (CAS 126-96-5) 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 204-814-9).
