- Product Description
Sodium Acetate 3-Water – Industrial Grade Buffer & pH Regulator for Versatile Applications
Established in 1988, Shanxi Zhaoyi Chemical Co., Ltd. is a seasoned professional manufacturer focusing on acetate chemical production. Covering a 27,000 ㎡ standardized production plant, we own a stable annual output of 150,000 tons for the full acetate product series. We specialize in supplying high-purity Sodium Acetate 3-Water (CAS NO. 6131-90-4, CH₃COONa·3H₂O) with a molecular weight of 136.08 g/mol. Featuring a stable crystallization water content of around 40%, this colorless and white crystalline product differs greatly from anhydrous sodium acetate in application scenarios and cost performance. It boasts excellent water solubility and stable pH buffering performance, widely used in wastewater treatment, textile processing, pharmaceutical production and laboratory analysis fields. Supported by complete ISO, KOSHER and HALAL certifications, our Sodium Acetate 3 Water delivers stable batch quality and reliable performance for global industrial clients’ core production processes.
Key Features & Benefits
The trihydrate form of our this product fits many industrial jobs. It works as a multi-functional pH regulator and a buffering agent across a wide range of processes. Its buffering capacity is strong and steady. That keeps solution pH values balanced and stops acid-base swings during continuous production.
The product dissolves quickly and evenly in standard water-based solutions. Fast batching and efficient production follow from that. Liquid regulators are messier to handle. This solid crystal form is easier to ship and to store. Dosing takes less effort as well, which makes on-site work much simpler.
This hydrated product costs less to produce and to buy than anhydrous sodium acetate. Core industrial performance stays the same. Its hydrated crystal structure holds steady, so ultra-dry storage conditions are not needed. That cuts storage and management costs for the company.
We have 35 years of production experience behind us. That is why each batch keeps nearly the same physical and chemical values. When quality holds steady, clients can line up their production settings and hit the quality control standards they work to.

How It Works
This product is a trihydrate buffer salt that works hard. In water, acetate and acetic acid sit in a reversible balance, and that balance is what keeps the pH steady. Small shifts toward acid or alkali get neutralized on their own. The pH then holds for a long time, so industrial reactions give the same result run after run.
In biological wastewater treatment, the acetate ions this product gives off act as a carbon source that breaks down easily and stays active. The acetate molecule is small, so it crosses bacterial cell membranes fast and wakes up the denitrifying microbes. Denitrification and nitrogen removal speed up as a result. Sewage plants can then reach their discharge limits without wild swings.
In textile dyeing, it holds the pH of the dye bath right where it should be. Dye uptake goes up because of that, and the color spreads more evenly. The buffer stays steady, so the outcome is predictable and easy to control. Fewer pieces get thrown out from pH drift.
Applications
Wastewater Treatment: A good fit for biological denitrification in municipal and industrial sewage plants. It supplies enough carbon, and that carbon stays stable, so nitrogen removal works better. Water quality at the outlet also holds steady.
Textile Industry: It adjusts pH and adds buffering help across many fabric dyeing processes. Standard dyeing setups suit it well, since no strict anhydrous conditions are required. Dyeing conditions get better, and the finished fabric turns out stronger.
Pharmaceutical Manufacturing: In drug formula work and synthetic reactions, it acts as a pH buffering agent. Reaction conditions stay steady. That keeps drug products safe and stable.
Laboratory Analysis: Labs use it a lot when they prepare buffer solutions. It also handles routine pH calibration and adjustment. Analytical tests get an accurate, stable base, so results stay precise.

FAQ
Q: How should this product normally be stored?
A: A1: Keep the product in packages that are sealed tight. Store them in a warehouse that is cool, dry, and has good airflow. To hold the product stable, keep it away from high heat, damp air, and strong oxidants.
Q: Can sodium acetate 3 water take the place of anhydrous sodium acetate in every case?
A: A2: For normal industrial uses, it works fine. Wastewater treatment and textile dyeing are two examples, since water content does not change how production runs there. Chemical synthesis that reacts to water is a different story. There you still need the anhydrous grade.
Q: How long is the shelf life if stored properly?
A: A3: With standard sealed, dry storage, the product stays stable for a long time. Do not leave it in ultra-dry air for long periods. That keeps crystal water from slowly escaping.
Q: Is this industrial grade suitable for food processing applications?
A: A4: This product is industrial grade. Use it only for industrial production. Need food-grade products? Talk to our team. They can give you food-grade spec support.
Q: Can packaging be made to our own design, and are there discounts for bulk orders?
A: A5: Yes. We support customized packaging for bulk orders and provide exclusive preferential pricing for large-volume and long-term cooperative customers to reduce your procurement cost.
