Sodium Acetate Trihydrate Crystal

Sodium Acetate Trihydrate Crystal – High-Purity Industrial & Food-Grade Buffering Solution

Shanxi Zhaoyi Chemical Co., Ltd. began in 1988. Acetates are our line of work, and the production technology behind them is mature. Solid industry experience comes with that. A standardized production base of 27,000 ㎡ turns out 150,000 tons of acetate products a year. Global clients buy Sodium Acetate Trihydrate Crystal (CAS NO.: 6131-90-4, CH₃COONa·3H₂O) from us. The crystal is clear and colorless. Water dissolves it easily, and the particles share a uniform structure. As a pH regulator and buffering agent, it stays steady and reliable. Our certification management is strict. ISO approval is in place, and so are KOSHER and HALAL. Purity comes in at 99.0% or above, which satisfies international high-standard quality requirements. Pharmaceutical manufacturing is one place it gets used. Textile processing plants buy it as well, and food processing is a third. Phase-change heat storage is another field that relies on it. Stable batch quality has built a strong name in the European and American markets, and in Asia too. Laboratory research depends on it, and so does industrial mass production. Professional thermal storage system applications use it as well.

Key Features & Benefits

Old-style pH adjusting agents do not perform as well. Our this product buffers better, and it holds that performance steady. Store it in different conditions and the trihydrate crystal structure keeps its physical and chemical properties. In water it dissolves fast and completely. That makes it a fit for automated batching and continuous production processes.

This product enables precise pH adjustment and stable control in the range of 8.0–9.5, which is very suitable for sensitive chemical reaction and formulation production scenarios. Its uniform crystal particle distribution effectively avoids blockage and failure of automatic dosing equipment, greatly improving production efficiency and reducing equipment maintenance frequency.

Different from anhydrous sodium acetate products, our trihydrate crystals come with stable built-in crystal water content of 36.0%–41.0%. The fixed moisture content simplifies material handling and environmental control procedures in humidity-sensitive production workshops, and completely solves the dust pollution and material waste problems of traditional powdered regulators.

Benefiting from reliable hygroscopic and phase-change properties, the product realizes efficient latent heat storage and release at 58°C. This thermal cycle characteristic effectively solves energy conservation and temperature control problems of industrial heating systems and constant-temperature equipment, providing a stable and efficient solution for industrial thermal management.

Technical Specifications

How It Works

Three water molecules bond tightly to every crystal unit of our Sodium Acetate Trihydrate Crystal. Once dissolved in water, the crystal splits apart fully into sodium ions and acetate anions. Together they form a stable acetic acid conjugate acid-base buffer pair system.

This buffer system does its job well. It offsets and blocks pH swings that come from acid or alkali added from outside. The alkalinity of the solution stays steady. Reaction conditions also stay stable during exothermic chemical reactions and long-term standing storage. That way, product quality does not shift because of pH changes.

At an ambient temperature of 58°C, the crystal changes phase in a stable way. It takes in a large amount of latent heat. The temperature does not rise much. When it cools, the crystal recrystallizes. Stored heat comes back out at a steady rate. This gives a continuous and reliable constant-temperature heat supply for industrial heating and building temperature control systems.

Acetate ions also have mild and safe bacteriostatic activity. They can work with organic acid components to stop Gram-negative bacteria from multiplying. This cuts the use of many additives in food and material preservation formulas. Production steps get simpler, and overall costs go down.

Applications

Pharmaceutical Manufacturing: Companies use it as a special buffer in injection solutions and in tablet coating. It holds the pH of drug products steady for the whole shelf life. High-purity grades match pharmacopoeia standards. They also show up a lot in API synthesis and in the making of pharmaceutical preparations.

Textile Processing: In dyeing and finishing baths it works as a pH regulator and a high-efficiency auxiliary. Dyeing comes out more even, and colors hold better. At the same time, it cuts alkaline corrosion and damage to natural fiber fabrics, so the fabric texture stays intact.

Laboratory Research: It is a standard reagent for making buffer solutions in analytical chemistry and molecular biology. Solubility stays stable, and reactions can be controlled. That gives experimental data high repeatability and accuracy. Research institutions like it for that reason.

Phase-Change Materials: This is the main latent heat storage medium used in reusable heating pads and in building systems that hold a steady temperature. At 58°C it changes phase. That number lines up well with the temperature people find comfortable, and it also fits what most industrial processes need.

Industrial Processing: It gets used to adjust acidity in leather tanning, concrete retarding and photographic developing solutions. Mineral acid regulators work too, but this one does not corrode metal. That means production equipment lasts longer.

Sodium Acetate Trihydrate Crystal vs Other Products

Certifications & Compliance

Our production base strictly implements ISO 9001:2015 quality management system standards to ensure consistent specifications and stable quality of each batch of products. Equipped with valid KOSHER and HALAL certifications, our products can meet the compliant production and application requirements of high-standard food and pharmaceutical industries.

All food-grade products fully comply with FCC food chemical code and EU E262(i) industry standards. Strict heavy metal and impurity control indicators meet FDA GRAS safety certification requirements, supporting direct food contact and clean-label product development.

Packaging Options

Standard Industrial Grade: The product comes in 25kg paper bags or woven plastic bags. Each bag has an inner PE liner that keeps moisture out, so the material stays dry during cross-border shipping and storage. For container loads and big industrial orders, palletized packaging is also available.

Food/Pharmaceutical Grade: The product goes into multi-layer thickened moisture-proof bags, and the inner liner is heat sealed. A tight seal like this keeps the crystals intact and holds their performance steady when humidity shifts. Standard orders ship in 25kg packs. Custom packaging is also available whenever a customer asks for it.

Manufacturing Process

We adopt mature and safe synthesis technology, using high-purity glacial acetic acid neutralized with sodium hydroxide or sodium carbonate as raw materials. Through precise temperature-controlled crystallization technology, standard trihydrate crystal products with stable water content are produced to ensure consistent phase-change performance of finished products.

Impurities come out through precision filtration in several stages. Purity stays above 99.0% thanks to this step. Centrifugal separation works together with vacuum drying to control the crystal water content between 36% and 41%. This keeps the core phase-change heat storage properties locked in.

Finished goods are packed automatically in a dust-free workshop held at a constant temperature. That stops moisture from getting in a second time. Before delivery, every batch is sampled and checked for pH value, heavy metal content and particle size distribution. Full compliance with the Sodium Acetate Trihydrate Crystal customer technical standards is confirmed this way.

FAQ

Q: How should you store the product so it doesn't break down?

A: A1: Store the product in packaging that stays sealed tight. Keep it in a dry warehouse with good airflow. Room temperature should not go above 30°C, and humidity should stay under 60%. Do not let it sit in direct sunlight. Never stack it together with strong oxidants. This stops caking and keeps performance from dropping.

Q: In formulas, can the trihydrate crystals be used in place of anhydrous sodium acetate as they are?

A: A2: Swapping it in directly is not advised. By weight, this product carries about 40% crystal water. So the dosage has to go up to 1.67 times the anhydrous dosage. That way the effective sodium acetate concentration still matches what the formula needs.

Q: What shelf life do you get with standard storage?

A: A3: Store it sealed and dry, under qualified conditions. Then it keeps its full technical specs and stable performance for 24 months. A quick visual check before use is a good idea.

Q: Can this food-grade product go into clean-label food production?

A: A4: Yes. Our food-grade products comply with EU E262(i) and FCC standards, and can be labeled as acidity regulator or vinegar salt, fully adapting to clean-label food market demands.

Q: Will the product affect yeast activity in fermentation production?

A: A5: It has negligible impact on yeast activity under standard dosage (0.1–0.5% flour weight), far to calcium propionate. It is the ideal additive for fermented baked food products.
