Addressing Leather Processing Challenges with 6153-56-6 Oxalic Acid Dihydrate
Over a decade of serving leather manufacturers across 50+ countries, we’ve witnessed how inconsistent acid purity disrupts tanning cycles—causing uneven dye absorption, extended processing times, and material waste. Many clients initially struggled with suppliers offering “99% purity” that failed to meet critical impurity thresholds, leading to costly rework and batch rejects.
Industrial Grade Oxalic Acid: Your Reliable Leather Cleaning Solution
Our Industrial Grade Oxalic Acid Dihydrate crystal delivers consistent 99.6% purity, specifically formulated to address the core challenges of leather cleaning and processing. With a stable supply capacity of 6000 tons monthly and 10+ years of chemical export expertise, we ensure your production lines never face delays due to material shortages or quality fluctuations.
Key Industrial Applications
As a versatile dicarboxylic acid, this product excels in leather cleaning by effectively removing mineral deposits and stains without damaging collagen fibers. Beyond leather processing, it serves as a critical reducing agent in mining operations, a cleaning agent for stone surfaces, and a raw material in various chemical synthesis processes—all strictly for industrial manufacturing use.
The Impact of Critical Specifications on Performance
The 99.6% purity level minimizes heavy metal impurities, preventing discoloration in leather products and ensuring compliance with EU REACH standards. Its defined melting point (101-102ºC) guarantees predictable dissolution rates, allowing precise control over pH levels during tanning. The medium strong acidity strikes the optimal balance between cleaning efficiency and fiber protection, while the white powder form ensures uniform mixing and dosage accuracy.
Benefits of Choosing Our Oxalic Acid Crystal
Opting for our Industrial Grade Oxalic Acid Crystal reduces production costs by minimizing rejections and rework—common issues with lower purity alternatives. Each batch adheres to ISO9001 quality standards, with SGS-certified purity ensuring consistent results across production runs. Our stable hydrolysis production process eliminates batch-to-batch variations, providing the reliability needed for large-scale leather manufacturing operations.
Our Commitment to Quality Assurance
Every shipment undergoes rigorous testing via HPLC and titration methods, with full traceability from raw material to final packaging. We provide a Certificate of Analysis (COA) for each batch, detailing key parameters like purity, moisture content, and heavy metal levels. Our dedicated quality control team ensures specifications are met before release, and we offer full replacement for any non-conforming products—no questions asked.
Certificate of Analysis & Documentation
All orders include a batch-specific COA and MSDS, with detailed test reports available upon request. For clients requiring additional verification, we can arrange third-party testing through SGS or equivalent laboratories, ensuring full transparency and compliance with your quality requirements.
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.
Streamlined Order Process for Industrial Buyers
Initiate your order by submitting an inquiry with your required quantity and packaging specifications. We’ll provide a detailed quotation including FOB/CIF pricing options, then arrange sample delivery for your testing and approval. Once specifications are confirmed, production begins immediately—with typical lead times of 7-10 days for bulk orders, supported by flexible shipping from Qingdao, Tianjin, or Shanghai ports.
