Oxalic Acid Dihydrate 99.6% (CAS 144-62-7): Resolving Leather Processing Inconsistencies
We’ve witnessed countless leather manufacturers struggle with uneven cleaning results and equipment corrosion caused by low-purity oxalic acid. Inconsistent batch quality often leads to rework rates exceeding 15%, while delayed shipments due to supply chain disruptions have cost businesses thousands in missed deadlines. These challenges aren’t just frustrating—they directly impact your bottom line.
Stable Supply for Uninterrupted Leather Production
Our Industrial Grade Oxalic Acid Dihydrate delivers the consistent purity (99.6%) your leather cleaning process demands. Backed by 10+ years of chemical export experience and a monthly production capacity of 6000 tons, we ensure steady supply even during peak seasons. This reliability has made us the preferred partner for leather manufacturers across 50+ countries, from small workshops to multinational enterprises.
Key Industrial Applications
As a critical Leather Cleaning Chemical, this dicarboxylic acid effectively removes lime deposits and stubborn stains from hides while maintaining fiber integrity. Beyond leather processing, its strong reducing properties make it valuable in mining operations for mineral extraction and stone cleaning applications where controlled acidity is required. All uses are strictly limited to industrial manufacturing processes.
Why Purity and Consistency Matter in Production
The 99.6% purity level minimizes impurities that cause equipment scaling and product defects in leather processing. Its precise melting point (101-102ºC) ensures predictable dissolution rates, allowing for accurate process control. The medium strong acidity strikes the perfect balance between cleaning efficiency and fiber damage prevention, while the white powder form guarantees uniform mixing. These specifications aren’t just numbers—they translate to 30% lower rework rates and 20% longer equipment lifespan in industrial settings.
The Cost of Compromise vs. Quality Investment
Choosing substandard oxalic acid may save 10-15% upfront, but typically results in 40% higher operational costs due to increased waste, rework, and equipment maintenance. Our product, certified by ISO9001 and SGS, meets strict international standards, reducing export inspection failures by 95%. The 25kg Bag packaging ensures easy handling and precise dosing, further optimizing your production efficiency and reducing material waste by up to 12%.
Our Quality Commitment: Beyond Compliance
Every batch undergoes rigorous testing through HPLC and titration methods to verify purity and composition. We provide a comprehensive COA with each shipment, detailing 18 critical parameters including heavy metal content and moisture levels. Our production facility operates under strict GMP guidelines, and we maintain a 100% replacement guarantee for any non-conforming products. With dedicated technical support available 24/7, we don’t just supply chemicals—we deliver peace of mind.
Certificate of Analysis & Documentation
Each order includes a batch-specific Certificate of Analysis and MSDS, providing full transparency on product quality and safety handling procedures. For critical applications, we can arrange third-party testing by SGS upon request. Detailed chromatographic analysis reports are available for review prior to purchase, ensuring complete confidence in product specifications.
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.
