Overcoming Leather Processing Challenges with 99.6% Dihydrate Oxalic Acid (CAS 6153-56-6)
In leather manufacturing, inconsistent acid concentrations often lead to uneven dye absorption and surface defects, while supply disruptions can halt production lines for weeks. We’ve witnessed how substandard oxalic acid batches caused a European tannery to reject 30% of their finished leather due to impurity-induced discoloration. After 12 years in chemical supply, we understand that reliability in both product quality and delivery is non-negotiable for industrial operations.
A Stable and Reliable Oxalic Acid Supply Solution
Our Industrial Grade Dihydrate Oxalic Acid addresses these critical pain points through 99.6% purity and strict batch consistency. With a monthly production capacity of 5,000 tons and strategic loading ports in Qingdao, Tianjin, and Shanghai, we’ve maintained 98% on-time delivery rates for over 6,000 global industrial customers. This stability ensures your manufacturing processes run without unexpected interruptions or quality compromises.
Typical Industrial Applications
As a versatile industrial chemical, this oxalic acid serves multiple manufacturing sectors beyond leather cleaning. Its strong reducing properties make it ideal for metal surface treatment, mineral processing, and stone cleaning applications. In textile production, it effectively removes rust stains and calcium deposits, while in the pharmaceutical industry, it acts as a raw material for intermediate synthesis – all strictly for industrial manufacturing purposes.
Why Key Specifications Matter
The 99.6% purity level minimizes impurities that cause unwanted side reactions in leather processing, ensuring consistent pH control during deliming and bating stages. Its defined melting point (101-102ºC) guarantees predictable dissolution behavior in aqueous solutions, critical for automated mixing systems. The medium strong acidity provides optimal reactivity without excessive fiber damage, while the dihydrate form ensures stable storage properties compared to anhydrous alternatives. Each parameter is calibrated to industrial standards, validated through ISO9001-certified quality control processes.
What You Gain With Our Industrial Oxalic Acid
Choosing our Dihydrate Oxalic Acid brings quantifiable benefits: reduced material waste from consistent reaction outcomes, lower rejection rates in finished products, and minimized downtime from reliable supply. Unlike low-purity alternatives that risk equipment corrosion and product contamination, our SGS-tested product meets strict international export standards, eliminating customs clearance delays. The 25kg packaging format optimizes handling efficiency while reducing storage space requirements – delivering both operational and cost advantages.
Why You Can Trust Us
Our quality assurance begins with raw material selection and continues through every production stage. Each batch undergoes rigorous testing including HPLC purity analysis, moisture content determination, and heavy metal screening. We provide comprehensive COA documents with every shipment, detailing exact specifications for your records. Our 10+ years of chemical export experience ensures full compliance with international shipping regulations (UN No. 3261), while our dedicated technical support team offers prompt assistance for application-specific questions. If any product fails to meet stated specifications, we guarantee replacement or full refund – no exceptions.
Certificate of Analysis & Documentation
Every delivery includes a batch-specific Certificate of Analysis with detailed test results, ensuring full traceability. MSDS documents are provided in multiple languages, containing comprehensive safety handling information. For critical applications requiring additional verification, we can arrange third-party testing through SGS or equivalent laboratories at your request. Historical batch data is retained for 5 years, allowing long-term quality trend analysis.
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.
How to Place Your Order
Initiate your order by submitting an inquiry with your required quantity and delivery timeframe. We’ll provide a detailed quotation including FOB/CIF pricing options and production lead times. For first-time customers, we recommend requesting a sample for qualification testing before full-scale ordering. Once specifications are confirmed, we’ll arrange production, inspection, and shipping with full documentation support for customs clearance.
