Combat Leather Processing Inefficiencies with High Purity CAS 144-62-7 Oxalic Acid
We've witnessed textile and leather manufacturers lose 15-20% of production batches due to inconsistent oxalic acid purity—impurities causing uneven dye absorption or leather hardening. When supply chains break, factories face 3-4 week delays waiting for reliable replacements. These are the industrial headaches that inspired our 10+ years of refining oxalic acid production standards.
Stable Supply for Uninterrupted Industrial Operations
Our 99.6% High Purity Oxalic Acid delivers the consistency your production line demands. Backed by a 6000 Tons/Month production capacity and strategic ports in Qingdao, Tianjin, and Shanghai, we've maintained 98.7% on-time delivery rates across 50+ countries. Whether you're processing leather or optimizing textile dyeing, our industrial grade oxalic acid ensures predictable results batch after batch.
Key Applications in Industrial Manufacturing
As a critical auxiliary in leather cleaning processes, this dicarboxylic acid effectively removes lime and mineral deposits without damaging collagen fibers. In the textile industry, it functions as a reducing agent and pH adjuster, enhancing dye fixation and brightness. Additional industrial uses include mineral processing and stone cleaning, where its medium strong acidity provides controlled reactivity essential for precision manufacturing.
The Technical Impact of 99.6% Purity
Our 99.6% purity specification isn't arbitrary—it directly addresses production challenges. Higher purity minimizes metallic ion impurities that cause discoloration in leather finishing. The tight solubility control (soluble in water/ethanol, insoluble in benzene) ensures uniform solution preparation, preventing streaking in textile applications. At 1.772 g/cm³ density, our oxalic acid offers consistent dosing, reducing material waste by up to 12% compared to lower density alternatives. Each parameter is engineered to solve real manufacturing problems.
Risk Reduction Through Quality Compliance
Choosing substandard oxalic acid introduces hidden costs: rejected batches, equipment corrosion from excess impurities, and regulatory penalties. Our ISO9001-certified production ensures compliance with REACH and EU chemical regulations, eliminating customs clearance delays. With SGS-verified purity and MSDS documentation, you mitigate liability while protecting your production reputation. Our Leather Cleaning Oxalic Acid delivers not just a chemical, but a risk-mitigation solution for your supply chain.
Our Quality Assurance Protocol
Every batch undergoes triple testing: initial HPLC analysis for purity, titration for acidity verification, and ICP-MS screening for heavy metals (Pb < 5ppm, As < 3ppm). We provide batch-specific COA reports with every shipment, including chromatograms and solubility test results. Our quality control laboratory operates 24/7, with technical staff available to interpret data and address concerns. If specifications aren't met, we arrange replacement shipments within 72 hours—no questions asked.
Certificate of Analysis & Documentation
Each delivery includes a comprehensive COA with batch-specific data, signed by our quality control manager. MSDS documents are updated quarterly to reflect the latest regulatory requirements. For critical applications, we can provide additional testing such as particle size distribution or moisture content analysis upon request. Historical batch data is retained for 5 years, supporting your quality audit 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 Industrial Procurement Process
Begin by submitting your requirements through our inquiry system, specifying quantity, delivery timeline, and any special documentation needs. We'll provide a detailed quotation including FOB/CIF pricing options within 24 hours. Sample requests are processed within 3 business days, with full batch production typically completed in 7-10 days. All shipments include the complete documentation package for customs clearance, ensuring smooth logistics from our factory to your facility.
