Overcoming Leather Processing Challenges with High-Purity Oxalic Acid Dihydrate CAS 144-62-7
In leather manufacturing, inconsistent cleaning efficiency due to purity fluctuations can lead to uneven dye absorption and product quality variations. We’ve worked with over 500 leather processing plants across Europe and Southeast Asia, where 78% reported reduced production rejects after switching to stable 99.6% purity industrial grade oxalic acid. Batch-to-batch variations in lower-grade products often cause unpredictable results in deliming and cleaning processes, disrupting production schedules and increasing waste.
A Stable and Reliable Chemical Supply Solution for Industrial Applications
Our Oxalic Acid Dihydrate CAS 144-62-7 addresses these challenges through strict quality control and规模化 production capacity of 6000 tons monthly. As a leading chemical export platform with 10+ years of experience serving 6,000+ industrial customers worldwide, we ensure consistent supply even during peak demand periods. The 99.6% industrial grade specification minimizes impurities that can interfere with leather cleaning and stone processing applications, providing reliable performance across diverse manufacturing environments.
Typical Industrial Applications
Industrial Grade Oxalic Acid finds primary use in leather processing as a cleaning and deliming agent, effectively removing lime deposits and preparing hides for tanning. Its reducing properties make it valuable in mining operations for mineral processing and metal surface treatment. Additionally, it serves as a cleaning agent for stone surfaces and industrial equipment, where its strong chelating ability dissolves mineral deposits without damaging substrates. All applications are strictly limited to industrial manufacturing processes.
Why Key Specifications Matter in Industrial Processing
The 99.6% purity level of our Oxalic Acid Dihydrate is critical for maintaining process consistency—lower purity can introduce impurities that cause streaking in leather cleaning or incomplete mineral dissolution in mining applications. The controlled melting point (101-102ºC) ensures stable performance in heating processes, while its solubility profile (soluble in water, ethanol; insoluble in benzene) allows precise formulation control. The medium strong acidity provides optimal reactivity for deliming without over-etching leather fibers, balancing efficiency with material protection. These specifications directly translate to reduced process variability and improved end-product quality.
Benefits of Using Our High-Quality Oxalic Acid Dihydrate
Choosing compliant, high-purity Oxalic Acid Dihydrate reduces production risks compared to substandard alternatives. Our ISO9001-certified manufacturing process ensures each batch meets consistent quality standards, minimizing the likelihood of production delays caused by material failures. The SGS-verified purity helps manufacturers comply with international export standards, avoiding customs issues and market access barriers. For leather processors, this translates to more uniform dye uptake and 15-20% reduction in rework rates. The stable supply chain, supported by multiple loading ports (Qingdao, Tianjin, Shanghai), ensures uninterrupted production even for large-scale operations.
Our Quality Assurance and Reliability Commitment
Every batch of our Oxalic Acid Dihydrate undergoes comprehensive testing including HPLC purity analysis and moisture content determination. We provide a Certificate of Analysis (COA) with each shipment, detailing key parameters such as purity, density, and impurity levels. MSDS documentation is available for all shipping destinations to ensure safe handling and regulatory compliance. Our production facility maintains strict quality control from raw material selection through final packaging, with full traceability for every lot produced. If any product fails to meet the specified 99.6% purity standard, we offer unconditional replacement to minimize your production disruption.
Certificate of Analysis & Documentation
Each delivery includes a batch-specific COA and MSDS, providing detailed quality parameters and safety handling instructions. For critical applications requiring additional verification, specific batch test data including chromatographic analysis can be requested using your order number. Full technical documentation supports compliance with REACH, OSHA, and other regional regulatory requirements for industrial chemical handling.
Storage & Handling
- Store in a cool, dry, well-ventilated area, sealed and away from direct sunlight.
- Keep away from incompatible materials, food and feed sources.
- Handle with appropriate personal protective equipment (gloves, goggles, lab coat).
- Follow good industrial hygiene practices. Avoid inhalation and skin contact.
- Refer to MSDS for detailed storage and safety instructions.
Simple Order Process for Industrial Buyers
To place an order, submit your inquiry with required quantity and destination port, and our technical team will provide a detailed quotation including applicable trade terms (FOB/CIF). Sample evaluation is available for first-time customers to verify compatibility with your processes. Once specifications are confirmed, we arrange production and inspection, with full documentation provided prior to shipment. Our dedicated logistics team coordinates sea freight from Qingdao, Tianjin, or Shanghai ports to ensure on-time delivery.
