Addressing Dyeing & Leather Processing Challenges with Oxalic Acid CAS 144-62-7
For over a decade in chemical manufacturing, we’ve witnessed how inconsistent oxalic acid purity disrupts dyeing processes—causing uneven color absorption and increased wastewater treatment costs. Leather processors frequently report batch variations leading to unpredictable tanning results and production delays. These challenges aren’t just frustrating; they directly impact your bottom line through material waste and missed deadlines.
A Stable Chemical Supply Solution for Industrial Applications
Our Industrial Grade Oxalic Acid CAS 144-62-7 addresses these pain points with 99.6% purity and strict quality control. Backed by 6,000+ tons monthly production capacity and ISO9001 certification, we ensure consistent supply for large-scale dyeing and leather processing operations. As a leading chemical export platform with 10+ years of experience, we’ve established reliable logistics channels through Qingdao, Tianjin, and Shanghai ports to minimize delivery uncertainties.
Typical Industrial Applications
Industrial Grade Oxalic Acid finds critical use in leather processing as a deliming agent, effectively removing lime from hides to prepare them for tanning. In the dyeing industry, it serves as a reducing agent and pH adjuster, improving dye penetration and color fastness. Additional industrial applications include metal surface treatment, cleaning stone surfaces, and mining operations—all strictly within industrial manufacturing parameters.
Why Key Specifications Matter for Production
The 99.6% purity of our oxalic acid minimizes impurities that cause unwanted side reactions in dye baths, ensuring consistent color results across production runs. Its defined melting point (101-102ºC) guarantees stable performance in heating processes, while solubility characteristics (soluble in water/ethanol, insoluble in benzene) allow precise formulation control. Medium strong acidity provides optimal deliming efficiency in leather processing without damaging collagen fibers, and the 25kg bag packaging ensures easy handling and storage in industrial facilities.
Benefits of Reliable Oxalic Acid Supply
Choosing high-quality oxalic acid reduces production costs by minimizing material waste from failed batches—a common issue with lower purity alternatives. Our SGS-certified product meets international export standards, eliminating customs clearance delays due to non-compliant materials. Consistent supply from our 6000 tons/month capacity prevents production line shutdowns, while strict quality control ensures your finished products meet customer specifications reliably. Ethanedioic Acid for Dyeing from our facility offers long-term cost stability through vertically integrated production.
Our Quality Assurance Process
Every batch of our oxalic acid undergoes comprehensive testing including HPLC purity analysis and moisture content determination. We provide a Certificate of Analysis (COA) with each shipment, detailing batch-specific test results. Our production process adheres to ISO9001 standards, with raw material traceability from hydrolysis to final packaging. If any product fails to meet specified parameters, we offer unconditional replacement or refund. Our technical support team provides guidance on proper handling and application specific to dyeing and leather processing needs.
Certificate of Analysis & Documentation
Each delivery includes a batch-specific COA with purity test results, heavy metal content, and physical property data. MSDS documents are provided for safe handling and regulatory compliance. For critical applications, we can arrange third-party SGS testing at customer request. Historical batch data is retained for five years and available for audit with proper authorization.
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 delivery terms (FOB/CIF available). We’ll provide a detailed quotation within 24 hours, including technical specifications and documentation samples. For first-time customers, we offer small sample quantities for evaluation before full-scale ordering. Once specifications are confirmed, production is scheduled with typical lead times of 7-10 days for standard orders.
