Oxalic Acid Crystal 99.6% (CAS 6153-56-6): Solving Leather Processing’s Purity Challenges
Industrial leather processors often face critical issues with inconsistent oxalic acid quality—fluctuating purity levels causing uneven dye absorption, batch variations leading to product rejects, and unreliable suppliers delaying production schedules. In our 10+ years serving leather manufacturers across 50+ countries, we’ve witnessed how these challenges directly impact operational efficiency and product quality.
A Stable Solution for Industrial Leather Cleaning
Our Industrial Grade Oxalic Acid Crystal (H2C2O4·2H2O 99.6%) addresses these core pain points through stringent manufacturing control. As a leading chemical export platform with self-operated import-export rights, we ensure each batch maintains 99.6% purity, providing the consistent performance required for leather cleaning and processing applications. Our established supply chain supports stable monthly production capacity of 6000 tons, eliminating the risk of delayed shipments.
Key Industrial Applications
This Ethanedioic Acid 6153-56-6 finds primary use in leather processing as a cleaning and bleaching agent, effectively removing stains and mineral deposits from hides. Beyond leather, its properties make it suitable as a reducing agent in mining operations and for cleaning stone surfaces. All applications are strictly limited to industrial manufacturing processes, adhering to safety protocols for chemical handling.
Critical Specifications for Optimal Performance
The 99.6% purity level is critical for minimizing副反应 in leather processing, ensuring consistent dye uptake and reducing waste. Its solubility in water (a key characteristic of Industrial Grade Oxalic Acid Crystal) allows precise concentration control, while the medium strong acidity provides effective cleaning without damaging leather fibers. The white powder appearance indicates low impurity content, a visual confirmation of our quality standards. Melting point stability (101-102ºC) ensures reliable performance in various industrial temperature conditions.
Benefits of Reliable Oxalic Acid Sourcing
Choosing our 99.6% Oxalic Acid for Leather Cleaning eliminates the hidden costs of substandard materials—reduced product rejects, consistent processing times, and compliance with international quality standards. Unlike lower purity alternatives that may contain heavy metal impurities, our product meets ISO9001 and SGS certification requirements, supporting your export compliance needs. The stable monthly production capacity ensures long-term supply security, protecting your manufacturing schedule from unexpected disruptions.
Our Quality Assurance Commitment
Every batch undergoes comprehensive testing including composition analysis and purity verification through advanced laboratory methods. We provide a Certificate of Analysis (COA) with each shipment, detailing exact specifications for that batch. MSDS documentation is included for safe handling procedures. Our quality control process follows strict ISO9001 guidelines, with full traceability from raw material sourcing to final packaging. If any product fails to meet specified parameters, we offer unconditional replacement to ensure your production continuity.
Certificate of Analysis & Documentation
Each delivery includes a batch-specific COA with detailed purity testing results and compliance information. MSDS documents are provided for proper safety handling and storage procedures. For specific batch verification, detailed test data can be requested using your order reference number, ensuring full transparency in our quality control process.
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.
