Oxalic Acid 99.6% Tech Grade: Addressing Leather and Stone Cleaning Industry Challenges
Inconsistent acid concentration in leather processing often leads to uneven dye absorption, while impurity-laden stone cleaning agents can cause irreversible surface etching. Over the past decade, we’ve assisted hundreds of manufacturers in resolving production delays caused by unstable chemical supplies—particularly critical in time-sensitive leather tanning and heritage stone restoration projects.
A Stable Solution for Industrial Cleaning Applications
Our Oxalic Acid 99.6% Tech Grade delivers the consistent purity required to eliminate these issues. With a monthly production capacity of 6000 tons and ISO9001-certified manufacturing processes, we ensure uninterrupted supply for industrial-scale cleaning operations, from leather processing lines to stone restoration sites across 50+ countries.
Typical Industrial Applications
This Industrial Oxalic Acid for Stone Cleaning serves as a powerful chelating agent in leather processing, effectively removing lime deposits from hides during dehairing. In stone maintenance, its medium-strong acidity (pH 1.3 in 0.1M solution) safely dissolves mineral stains without damaging calcareous surfaces. It also functions as a reducing agent in mining operations and metal treatment processes—strictly for industrial manufacturing use only.
Why Key Specifications Matter in Industrial Cleaning
The 99.6% purity level minimizes heavy metal impurities (≤0.001% Fe) that could compromise leather quality or cause stone discoloration. Its defined melting point (101-102ºC) ensures predictable dissolution behavior in aqueous solutions, critical for formulating consistent cleaning agents. The white powder appearance guarantees absence of color contaminants, while solubility in water (14.3g/100mL at 20ºC) allows precise concentration control—essential for avoiding over-etching in sensitive stone cleaning applications.
The Value of Reliable Oxalic Acid Supply
Using substandard oxalic acid risks product rejects, equipment corrosion, and compliance violations. Our SGS-tested White Oxalic Acid Powder meets REACH regulatory requirements, reducing import barriers for EU and North American clients. With 10+ years of chemical export experience, we mitigate logistics uncertainties through multi-port shipping options (Qingdao, Tianjin, Shanghai) and provide full documentation to streamline customs clearance—directly lowering your total landed costs.
Our Quality Assurance Commitment
Every batch undergoes HPLC purity analysis and moisture content testing (≤0.5%), with results documented in a Certificate of Analysis (COA) provided with each shipment. Our manufacturing facility maintains ISO9001:2015 certification, and we offer MSDS documents in 12 languages for global compliance. Should any technical issues arise, our dedicated chemical engineers provide 24-hour technical support, and we guarantee replacement of any non-conforming material within 7 days of receipt.
Certificate of Analysis & Documentation
Each delivery includes a batch-specific COA with test results for key parameters including purity, heavy metals, and moisture content. MSDS documents are provided as standard, detailing safe handling procedures and regulatory compliance information. For critical applications, we can arrange third-party testing through SGS or Intertek at client request.
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
Begin by submitting an inquiry with your required quantity and delivery terms (FOB/CIF available). We provide samples for qualification testing within 3 business days, followed by formal quotation and contract. Production typically takes 5-7 days for orders under 500 tons, with full documentation package (commercial invoice, packing list, COA, MSDS) delivered electronically prior to shipment.
Frequently Asked Questions
Q: What is the shelf life of your oxalic acid?
A: When stored properly in sealed original packaging, our oxalic acid maintains specification for 24 months from the manufacturing date.
Q: Can this product be used for food or pharmaceutical applications?
A: No. This is industrial grade material intended solely for manufacturing and laboratory research use, not for human consumption or medical purposes.
Q: What documentation is provided with each shipment?
A: Every order includes commercial invoice, packing list, Certificate of Analysis (COA), Material Safety Data Sheet (MSDS), and customs declaration documents.
Q: Do you offer custom packaging options?
A: Yes, we can provide 500kg or 1000kg jumbo bags in addition to standard 25kg bags for bulk orders exceeding 10 tons.
Q: How is product purity verified?
A: Purity is determined by titration and HPLC analysis, with results recorded in the batch COA. Customers may request additional testing by independent laboratories at their expense.
