Oxalic Acid (CAS 144-62-7): Resolving Leather Tanning Industry’s Purity & Consistency Challenges
For over a decade in the chemical supply chain, we’ve witnessed leather tanneries struggle with oxalic acid batches that vary in purity by 2-3%, causing uneven collagen fiber swelling and unpredictable tanning results. Researchers in stone cleaning applications often report inconsistent solubility leading to inefficient mineral deposit removal. These issues aren’t just product problems—they disrupt production schedules and increase material waste.
Stable 99.6% Oxalic Acid: Your Reliable Industrial Solution
Our Industrial Grade Oxalic Acid addresses these critical pain points with a guaranteed 99.6% purity level, ensuring consistent performance across leather tanning, stone cleaning, and reducing agent applications. Backed by 10+ years of chemical export expertise and ISO9001 certification, we deliver a product that meets the stringent requirements of 6,000+ global industrial customers, including multinational manufacturing enterprises and developing country manufacturers.
Key Industrial Applications
As a dicarboxylic acid, oxalic acid serves as a vital intermediate in leather tanning processes, facilitating controlled dehairing and fiber loosening. Its reducing properties make it effective in mining operations for metal extraction, while its chelating ability enables efficient stone cleaning by dissolving calcium and iron deposits. This industrial-grade product is engineered for these specific industrial processes, ensuring optimal results in large-scale manufacturing environments.
Why 99.6% Purity & Key Specifications Matter
The 99.6% purity level of our oxalic acid directly impacts process efficiency—lower purity can introduce impurities that interfere with tanning reactions, leading to substandard leather quality. Its medium strong acidity (pKa1 1.27) ensures controlled pH adjustment without excessive fiber damage. The precise melting point (101-102ºC) and boiling point (365.10ºC) guarantee stability during industrial heating processes. With a density of 1.772 g/cm³, our oxalic acid powder offers consistent handling and dosing, critical for maintaining batch-to-batch uniformity in large-scale production.
The Value of Choosing Our Oxalic Acid
Opting for our ISO9001 and SGS-certified oxalic acid minimizes the risks associated with substandard chemicals—avoid production delays from inconsistent material performance and reduce reject rates caused by impurity-related defects. Unlike unreliable suppliers, our 6000 tons/month production capacity ensures steady supply even during peak demand periods. For leather manufacturers, this translates to consistent product quality and predictable production costs, while stone cleaning operations benefit from reliable efficacy and reduced material usage.
Our Quality Commitment: Beyond Compliance
Every batch of our oxalic acid undergoes rigorous quality control testing, including composition analysis via HPLC and moisture content verification. We provide a comprehensive Certificate of Analysis (COA) with each shipment, detailing key parameters like purity, heavy metal content, and pH. Our compliance with UN No. 3261 regulations ensures safe transportation, while our HS Code 29171110 classification simplifies customs clearance. If product specifications don’t match our COA, we offer unconditional replacement to maintain your production continuity.
Certificate of Analysis & Documentation
Each delivery includes a batch-specific COA with detailed test results, ensuring full traceability from production to delivery. MSDS documents are provided in compliance with international safety standards, containing handling precautions and emergency procedures. For critical applications requiring additional verification, we can arrange for third-party SGS testing at an additional cost, 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 sending an inquiry with your required quantity and delivery timeline. We’ll provide a quotation under your preferred trade term (FOB Qingdao/Tianjin/Shanghai or CIF) within 24 hours. For first-time buyers, we offer sample testing (500g-1kg) to verify compatibility with your processes. Once specifications are confirmed, we’ll arrange production and delivery, with full documentation for customs clearance included as standard.
