Ruiheng Biotech offers high-purity Sodium Acetate (CAS 127-09-3/6131-90-4) in Food, Pharma & Industrial grades. As a certified manufacturer, we provide stable pH buffering solutions with factory-direct pricing and global delivery.
Technical Support Ensure compliance and safety with our comprehensive product documentation.
Sodium acetate is a widely used food additive and buffering agent in the food, pharmaceutical, and industrial industries. As a professional sodium acetate supplier and manufacturer in China, we provide food grade (E262), pharmaceutical grade, and industrial grade sodium acetate with high purity, stable quality, and reliable global supply. Our products meet international standards such as FCC, USP, and EU regulations and are exported worldwide.
Sodium acetate (E262) is commonly used as a buffering agent, acidity regulator, and preservative synergist in food and industrial formulations.

Sodium Acetate is the sodium salt of acetic acid, a multifunctional chemical widely used as a food additive, buffering agent, pH stabilizer, flavor enhancer, and chemical intermediate.
With its excellent water solubility, stable buffering capacity, and GRAS (Generally Recognized As Safe) status, sodium acetate is widely used in food, pharmaceutical, biotechnology, and industrial applications.
We supply high-purity sodium acetate in multiple grades, including food grade, pharmaceutical grade, and industrial grade, available as anhydrous powder, trihydrate crystals, or spherical granules. All products are manufactured under strict quality control systems with full traceability and complete documentation.

Note: Sodium acetate functions as a buffer, flavor enhancer, and preservative synergist, but unlike calcium acetate, it does not provide mineral fortification. Its solution is weakly alkaline due to acetate hydrolysis:
CH3COO⁻ + H2O ⇌ CH3COOH + OH⁻
