Overcoming Leather Processing & Stone Cleaning Challenges with High-Purity Oxalic Acid CAS 6153-56-6
We've witnessed countless production delays caused by inconsistent oxalic acid purity—fluctuations as small as 0.5% can trigger uneven dye absorption in leather processing or leave unsightly residues on stone surfaces. Our 10+ years serving leather tanneries and stone restoration workshops across 50+ countries have taught us that reliable sourcing isn't just about price; it's about avoiding costly rework and maintaining production schedules.
Industrial Grade Oxalic Acid: Your Stable Supply Solution
Our Industrial Grade Oxalic Acid H2C2O4·2H2O delivers consistent 99.6% purity, eliminating the batch-to-batch variations that disrupt manufacturing processes. Backed by a 6,000 tons/month production capacity and strategic shipping ports in Qingdao, Tianjin, and Shanghai, we ensure timely delivery even for large-scale orders—critical for maintaining your production workflow without interruption.
Key Industrial Applications
This versatile dicarboxylic acid serves as an essential reducing agent in leather processing, effectively removing lime and mineral deposits during beamhouse operations. In stone cleaning applications, its controlled acidity safely dissolves efflorescence and rust stains without damaging delicate surfaces. Additional industrial uses include mining operations and as a raw material in chemical synthesis, demonstrating its broad utility across manufacturing sectors.
Critical Specifications for Optimal Performance
The 99.6% purity level minimizes impurities that cause unwanted side reactions in leather processing, ensuring uniform hide preparation and dye uptake. Its defined melting point (101-102ºC) allows precise temperature control during dissolution, while the medium strong acidity strikes the perfect balance between cleaning efficacy and material safety—too weak and it fails to remove deposits, too strong and it damages substrates. The white powder form ensures easy handling and accurate dosing, reducing waste and ensuring consistent results.
Why Quality Oxalic Acid Translates to Business Value
Choosing our ISO9001-certified Industrial Grade Oxalic Acid protects your bottom line by reducing reject rates and rework costs. Inferior products with inconsistent purity often contain heavy metal residues that fail export compliance standards, risking shipment delays and financial penalties. Our rigorous quality control ensures each batch meets international standards, while our stable supply chain prevents production halts—a particular advantage in today's volatile chemical markets where sudden price spikes and shortages are common.
Our Quality Commitment: Beyond Compliance
Every batch undergoes comprehensive testing via HPLC and titration methods to verify purity and composition, with results documented in a detailed Certificate of Analysis (COA) provided with each shipment. Our production facilities maintain strict ISO9001 standards, from raw material selection through final packaging. Should any product fail to meet your specified requirements, our no-questions return policy ensures your satisfaction. We also offer dedicated technical support to help optimize your application processes, drawing on our decade of experience serving diverse industrial sectors.
Certificate of Analysis & Documentation
Each delivery includes a batch-specific COA with full purity data, heavy metal analysis, and physical property measurements. MSDS documents are provided in multiple languages to support global safety compliance. For critical applications requiring additional verification, we can arrange third-party SGS testing at your request, with results typically available within 5-7 business days.
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 timeline. We'll provide a detailed quotation including FOB/CIF pricing options and product availability. For first-time buyers, we offer small sample quantities for qualification testing. Once specifications are confirmed, our standard production lead time is 7-10 business days, with flexible shipping options to major industrial hubs worldwide.
