Sodium Acetate (CAS 127-09-3) is the sodium salt of acetic acid, a white crystalline powder that is highly soluble in water and acts as a buffer in the pH 3.5-5.6 range, and it is used as a flavoring agent in pickles, in dialysis solutions, and to accelerate concrete. It is produced from glacial acetic acid neutralization, suitable for food and industrial uses.

Sodium Acetate
Applications
Applied in food as flavoring agent in pickles; in pharmaceuticals for dialysis solutions; in textiles for dyeing assistants; in heat packs for reusable warmth; and in concrete for acceleration.
Safety & Risks
Mild irritant to skin and eyes; ingestion causes nausea in large amounts. Low fire risk but hygroscopic; handle with gloves to prevent moisture absorption; per EFSA, safe in regulated quantities.
Packaging
Packed in 25 kg woven polypropylene totes with inner barriers against humidity. Keep in acetate storage bays with dehumidifiers for product integrity.
