Types of Sodium Acetate
Our sodium acetate is manufactured according to stringent international standards, ensuring reliability in sensitive chemical reactions.
- Powerful Buffer: Effectively maintains stable pH levels in biochemical and industrial processes, resisting pH changes caused by acid and alkali additions.
- Highly Effective Mordant & Neutralizing Agent: In the textile and leather industries, it can be used as a neutralizing agent and mordant for sulfuric acid to improve dye fixation.
- Latent Heat of Crystallization: Sodium acetate trihydrate is often used in “hot-ice” processes because it releases a large amount of heat when crystallizing in supersaturated solutions.
- High Purity and Low Impurities: Our food-grade and pharmaceutical-grade products have strictly controlled iron, heavy metal, and chloride content.
What is Sodium Acetate Used for
- Wastewater Treatment: Serves as a high-quality carbon source, improving denitrification efficiency and promoting sludge purification.
- Food Additives: Used as a preservative (e.g., in bread, sausages) and flavoring, adjusting acidity and extending shelf life.
- Hand Warmers/Hot Pots: Utilize the physical property of releasing heat when a supersaturated solution crystallizes.
- Textile Printing and Dyeing: Used as an auxiliary agent to neutralize strong acids, adjust pH, and improve dye uniformity.
- Leather Tanning: Serves as a buffer and pickling agent, regulating the acid-base balance during leather processing.
- Pharmaceutical Manufacturing: Used in the preparation of dialysis fluids and rehydration solutions to maintain electrolyte balance in the human body.
Q&A About Sodium Acetate
It depends on your application and cost requirements:
Anhydrous (CH3COONa): 99% min purity. Best for applications requiring high concentration or moisture control (e.g., specific chemical synthesis).
Trihydrate (CH3COONa ·3H2O): ~60% purity. More cost-effective and widely used in wastewater treatment and textile dyeing where water content doesn’t affect the process.
As a high-quality carbon source, our sodium acetate is rapidly biodegradable. It speeds up the denitrification process (nitrogen removal) compared to traditional sources like methanol, and it is much safer to handle and store due to its non-toxic, non-flammable nature.
We provide various grades to meet global standards:
Industrial Grade: For sewage treatment and textiles.
Food Grade (E262 / FCC): For food preservation and acidity regulation.
Pharma Grade (USP/BP): For medical dialysis and buffer solutions. Each batch is issued with a Certificate of Analysis (COA).
Sodium acetate is hygroscopic. To ensure product flowability upon arrival, we use dual-layer packaging: a durable outer woven bag and a high-strength, heat-sealed PE inner moisture-proof liner. For humid regions, we also offer vacuum-sealed options.
Yes. We offer free samples (typically 200g-500g) so you can verify the purity and performance in your own lab. Contact our sales team with your courier account details, and we will arrange the shipment within 24 hours.
Sodium Acetate is standardly packed in 25kg bags. Customized packaging can be arranged based on customer requirements.
Store in a cool, dry, and well-ventilated area. Keep the bag tightly sealed in moisture-proof packaging to prevent caking due to its hygroscopic nature.
