Why Choose Our Oxalic Acid?
99.6% Minimum Purity for Effective Performance
Your processes require precision. Our product maintains consistent high purity, which means you use less product to achieve the same cleaning or treatment results. This translates directly to cost savings in your operations.
Superior Rust Removal Without Substrate Damage
Traditional mineral acids often corrode the base metal while removing rust. Our product provides controlled acidity that effectively chelates ferric oxide while preserving underlying metal integrity—critical for stainless steel passivation and specialized alloy preparation.
Biodegradable Chemistry for Environmental Compliance
Unlike harsh synthetic cleaners, oxalic acid decomposes naturally into CO₂ and water. You meet environmental regulations without sacrificing cleaning power, making your facility's chemical management simpler and safer.
Competitive Factory-Direct Pricing
By purchasing directly from our manufacturing facility, you eliminate middleman markup. We offer flexible MOQ options—from small trial batches for testing to full container loads for production scale.
Stable Batch-to-Batch Quality
Our in-house laboratory tests every production batch. You receive consistent product performance that your quality control team can rely on, with full Certificate of Analysis (CoA) documentation provided with each shipment.
Industrial Metal Surface Treatment
Use our oxalic acid as a high-performance pickling agent before metal passivation. It removes heat scale, atmospheric corrosion, and welding discoloration from stainless steel and specialized alloys without the aggressive substrate attack of hydrochloric or sulfuric acids.
Wood Restoration and Brightening
Professional restoration contractors and wood manufacturers depend on oxalic acid to neutralize tannins and eliminate dark water stains caused by iron-moisture reactions. The compound penetrates deep into wood pores, brightening timber without degrading lignin structure.
Rare Earth Element Extraction
In metallurgical operations, oxalic acid serves as a critical precipitating agent. Its high purity ensures clean precipitation of rare earth oxalates, which can be efficiently filtered and calcined to produce high-grade rare earth oxides.
Textile and Fabric Bleaching
The controlled acidity profile makes it ideal for neutralizing alkaline residues in textile processing while providing effective bleaching without fiber damage or secondary staining.
Laboratory and Analytical Chemistry
Research facilities utilize it as a standard reagent in redox titrations and as a chelating agent for metal ion analysis, where purity and consistent performance are non-negotiable.
Technical Properties You Can Depend On
Our Pure Oxalic Acid Powder exhibits a molecular weight of 90.03 g/mol (anhydrous form) with excellent solubility in water and ethanol. The strong acidity (pKa1 1.25) enables rapid reaction kinetics in both cleaning and chemical synthesis applications.
The product forms stable, water-soluble complexes with metal ions—particularly iron, calcium, and magnesium—making it exceptionally effective in descaling and chelation processes. The high whiteness index ensures no secondary discoloration during bleaching operations.
Quality parameters are tightly controlled:
- Iron content (Fe): ≤0.001%
- Heavy metals: Strictly limited per international reagent standards
- Moisture content: Controlled via Loss on Drying testing
- Ash content: ≤0.05% for high-end applications
Each bunch meets GB/T 1626-2008 or identical worldwide quality guidelines, confirmed through potassium permanganate titration and ICP-OES follow metal analysis.
Safety Handling Guidelines
Oxalic corrosive requires legitimate dealing with but is not classified as carcinogenic, mutagenic, or reprotoxic (CMR). Take after these down to earth security measures:
Personal Defensive Equipment
Wear nitrile gloves and security goggles amid taking care of. In dusty situations, utilize N95 particulate respirators to dodge inhalation.
Storage Requirements
Store in firmly fixed unique bundling in a dry area. The item is hygroscically steady when secured from moisture.
Spill Management
For dry spills, clear up carefully to minimize tidy era. For damp spills, flush with water and neutralize utilizing calcium carbonate or sodium bicarbonate some time recently disposal.
First Help Methods
- Skin contact: Wash thoroughly with soap and water
- Eye contact: Flush continuously for 15+ minutes and seek medical attention immediately
- Ingestion: Do NOT induce vomiting; provide milk or water and seek immediate medical care (calcium gluconate is the specific antidote)
A complete Safety Data Sheet (SDS) accompanies every shipment for your facility's compliance documentation.
Quality Control You Can Verify
Our quality management system covers every stage from raw material inspection to final product analysis. Each production batch undergoes:
- Purity Assay: Potassium permanganate titration verification
- Moisture Analysis: Loss on Drying testing for accurate dosing
- Trace Metal Screening: ICP-OES analysis for iron, lead, and arsenic
- Ash Content Testing: Ignition residue measurement for high-purity applications
- Batch Documentation: Full CoA with traceability for your quality records
This thorough testing convention guarantees you get item that meets your details each time, dispensing with generation disturbances caused by conflicting chemical performance.
