Oxalic Acid 99.6% Industrial Grade Powder: Addressing Purity Challenges in Leather & Stone Cleaning Applications
Industrial operations across leather processing and stone cleaning sectors frequently face critical issues with inconsistent Oxalic Acid purity—fluctuations as small as 0.5% can disrupt dye absorption uniformity or leave mineral deposits untreated. Our decade of supplying chemical raw materials to 6,000+ global industrial clients has revealed how batch-to-batch variations often lead to production delays and increased waste, particularly when sourcing from non-specialized suppliers.
Stable Supply of High-Purity Oxalic Acid for Industrial Processes
Our Industrial Grade Oxalic Acid powder (99.6%) delivers the consistency your production line demands. With a monthly capacity of 5,000 tons and ISO9001-certified manufacturing, we eliminate the supply chain risks that plague leather tanneries and stone processing facilities. Whether you require precise pH control in leather deliming or effective mineral stain removal in monument restoration, our Oxalic Acid ensures reliable performance across every batch.
Key Industrial Applications
As a dicarboxylic acid with strong reducing properties, Oxalic Acid finds indispensable use in leather industry processes including beamhouse operations and tanning, where it efficiently removes lime and calcium salts. In stone cleaning, its ability to dissolve calcium carbonate deposits makes it ideal for restoring granite, marble, and limestone surfaces. Additionally, it serves as a critical reducing agent in mining operations and metal surface treatment, demonstrating versatility across industrial sectors.
The Critical Role of Purity and Physical Properties
The 99.6% purity level of our Oxalic Acid minimizes metallic impurities that could compromise leather dyeing results or cause streaking on stone surfaces. Its white powder form ensures easy dissolution in water (critical for preparing consistent cleaning solutions), while the medium strong acidity (pKa1=1.27) provides controlled reactivity—strong enough to break down mineral deposits yet gentle enough to avoid surface etching when used as directed. The precise melting point (101-102ºC) further confirms manufacturing consistency, as deviations often indicate contamination or improper crystallization.
Quality Assurance: From Production to Delivery
Choosing substandard Oxalic Acid risks not only product quality but also compliance issues. Our product meets strict industrial standards with SGS-verified purity and complete documentation, including MSDS and COA for every shipment. This commitment to quality translates to tangible benefits: reduced rework rates in leather processing, consistent cleaning results in stone restoration, and compliance with international import regulations—critical advantages when supplying multinational manufacturing operations.
Our Quality Control Commitment
Every batch of our Industrial Grade Oxalic Acid undergoes comprehensive testing via HPLC and titration methods to verify purity and impurity levels. We provide batch-specific COA documents with detailed parameters including heavy metal content, moisture, and particle size distribution. Our production facility in Shandong operates under ISO9001 standards, with full traceability from raw material sourcing to final packaging. For clients with specialized requirements, we offer custom sample testing and technical support to ensure optimal application performance.
Certificate of Analysis & Documentation
Each shipment includes a Certificate of Analysis (COA) with batch-specific test results, ensuring full transparency of product quality. Material Safety Data Sheets (MSDS) are provided in compliance with international standards, detailing handling precautions and regulatory information. For critical applications requiring additional verification, specific batch test records can be requested with your order reference number.
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
