- Product Description
Industrial Sodium Acetate Trihydrate | High-Purity Crystals for Industrial Applications | Reliable Supply from Certified Manufacturer
Industrial Sodium Acetate Trihydrate (CAS 6131-90-4) is an acetate salt that is used to treat wastewater, dye textiles, melt ice, and make chemicals. Produced by Shanxi Zhaoyi Chemical Co., Ltd. — a manufacturer with over 30 years of industry experience —The product conforms with the requirements of corporate standard Q/140902ZYH002-2020, sodium acetate concentration of 58-60%, chloride content of not more than 0.03%, and moisture content of around 40%. 150,000 tonnes yearly production capacity with 27,000 m2 of business. All small and big B2B orders are processed with consistent batch quality and fast delivery within 5-7 working days.
Key Product Characteristics
The sodium acetate level is rigorously controlled at 58-60%, following domestic industrial production standards. Strict impurity control maintains a chloride content of ≤0.03%, suitable for sensitive downstream activities.
Crystals that dissolve in water won't form any problems during dosing or preparation. It's easier to store and move large amounts of it because it flows easily and doesn't cake.
Its ability to buffer and its constant weak alkalinity make it very useful for managing pH in chemical synthesis and wastewater treatment. Because its physical and chemical profile stays the same, it comes up well for procurement teams and plant operators.

Application Scenarios
This product serves as a reliable input across multiple industrial sectors.
Wastewater treatment: An important use is as a supplemental carbon source for municipal and industrial wastewater treatment facilities. It offers easily accessible carbon for denitrification processes, providing a cost-effective alternative or supplement to other carbon sources. Bulk ton-bag packaging is the most prevalent choice among plant operators for this application.
Textile & Printing Industry: This acetate salt is used as a buffering and fixing agent in the fabric dyeing and dye preparation operations. The steady weak alkalinity and the consistent solubility make it amenable to a broad variety of dye compositions.
De-icing and snow melting compounds are a significant portion of antifreeze and road de-icing formulae, especially in environmentally sensitive areas where chloride-based alternatives would be detrimental.
Pharmaceutical/Chemical Synthesis Sodium acetate trihydrate 99% purity is utilised in the production of medicinal intermediates and industrial catalysts. Our regular industrial grade is used for the manufacture of reagents and auxiliary chemicals.
Adhesive Compounding: Industrial Sodium Acetate Trihydrate can be added to adhesive mixtures as a functional additive that helps balance the pH and change the way the adhesive works.

Kosher Certification
Halal Certification (for applicable product grades)
We fully support on-site plant checks for clients in and outside of Australia. For international sales, paperwork with MSDS, COA, and safety certifications in more than one language can be made upon request.
Production Process & Quality Control
Sodium hydroxide and national standard acetic acid are the primary ingredients used in production. They also make a sodium acetate solution that has been controlled-neutralized, crystallised, centrifuged, and dried.
Obtaining the necessary anti-caking crystal structure while maintaining a 40% moisture content requires precise control of the drying temperature and centrifugal speed. The product's storage stability, solubility, and flowability are affected by these phases.
In accordance with the industry standard Q/140902ZYH002-2020, we test every batch for iron ions, water-insoluble materials, chloride, and sodium acetate.Backing for third-party testing and the supplier contract's technical requirements (e.g. SGS). No restrictions are put on the return or replacement of any batch that does not meet standards.
Packaging Options
Packaging is selected based on order volume, transportation requirements, and end-use conditions.
- 25 kg bags — Inner plastic liner with outer woven bag; suitable for small and medium batch purchases and easy warehouse handling
- 1,000 kg ton bags — Ideal for bulk buyers such as wastewater treatment plants
- Export packaging — Moisture-proof packaging meeting maritime transport standards, with additional moisture-resistant inner membrane
Custom packaging specifications and OEM labeling are available based on your target market and logistics requirements.
