Natrium Thioglycolate (commonly known as Sodium Thioglycolate, CAS Number: 367-51-1, Chemical Formula: HS-CH₂-COONa) is an essential organosulfur compound characterized by its dual functionality as a strong reducing agent and a highly selective complexing agent. As global industrial demand intensifies across mineral processing, personal care formulations, specialty organic synthesis, and microbiological media development, identifying authoritative Natrium Thioglycolate suppliers and factories with certified quality management systems is critical for commercial success.
In metallurgical and mineral flotation processes, Natrium Thioglycolate functions as a powerful depressant for copper and iron sulfides (such as pyrite and chalcopyrite) during the selective flotation of molybdenite ($MoS_2$). Unlike traditional toxic cyanide or sodium sulfide depressants, Natrium Thioglycolate presents an eco-friendly alternative with superior selectivity, reducing hazardous chemical exposure while maximizing recovery rates in modern processing plants.
To support procurement directors, technical chemists, and quality assurance specialists, the table below provides a comprehensive analytical breakdown of standard commercial Natrium Thioglycolate grades supplied by top-tier Chinese manufacturing facilities:
| Parameter Parameter | Technical Grade Liquid (40%-50%) | Cosmetic / Lab Grade Powder (≥98%) | Testing Methodology |
|---|---|---|---|
| CAS Registry Number | 367-51-1 | 367-51-1 | CAS Registry Standard |
| Appearance | Clear, light yellow to pinkish liquid | White to off-white crystalline powder | Visual Inspection |
| Active Content (Assay) | 40.0% – 50.0% min | 98.0% – 101.0% | Iodometric Titration / HPLC |
| pH (Direct / 10% Solution) | 6.5 – 8.5 | 6.8 – 8.0 | Potentiometric pH Meter |
| Iron (Fe) Content | ≤ 10 ppm | ≤ 5 ppm | ICP-OES / AAS |
| Heavy Metals (as Pb) | ≤ 10 ppm | ≤ 5 ppm | Colorimetric Standard |
| Solubility in Water | Completely Miscible | 100 g/L at 20°C (Clear solution) | Gravimetric Method |
The versatile reactivity of the thiol ($-\text{SH}$) and carboxylate ($-\text{COONa}$) groups makes Natrium Thioglycolate indispensable across multiple high-value industries:
In polymetallic ore processing plants (particularly across South America, South Africa, and North America), Natrium Thioglycolate serves as an organic depressant for pyrite, chalcopyrite, and galena. By selectively reducing and complexing metal ion sites on sulfide mineral surfaces, it significantly elevates molybdenum concentrate grade while maintaining environmental integrity without cyanide utilization.
The cosmetic formulation sector relies on high-purity (≥98%) Natrium Thioglycolate to cleave disulfide bonds ($S-S$) in keratin protein structures. This enables rapid, non-irritating hair removal creams and hair-waving liquids. Manufacturers require minimal heavy metal impurities (specifically Fe < 5ppm) to prevent discolored pinkish reactions in personal care products.
Pharmaceutical quality control labs use Fluid Thioglycolate Medium (FTM) to perform mandatory sterility testing on injectable therapeutics, peptides, and APIs. Natrium Thioglycolate acts as a reducing agent to lower the redox potential of the medium, creating an anaerobic environment that supports the growth of obligate and facultative anaerobes.
Global chemical procurement leaders increasingly partner with established Chinese chemical manufacturing clusters to secure scalable, cost-competitive, and quality-assured supplies of Natrium Thioglycolate. The competitive advantages of sourcing directly from verified Chinese factories include:
Chinese producers benefit from localized access to precursor materials such as chloroacetic acid and sodium hydrosulfide/sulfur sources. Integrated raw material supply chains protect international buyers from extreme market price volatility and ensure uninterrupted production cycles even during global supply chain bottlenecks.
With production footprints reaching over 250,000 square meters, modern chemical complexes offer flex-scale capacity ranging from multi-ton liquid ISO tanks to specialized vacuum-sealed 25kg fiber drums with double PE inner bags for high-purity crystalline powders.
Top exporters possess direct access to major deep-water seaports (such as Shanghai, Qingdao, and Ningbo), offering specialized Dangerous Goods (DG) maritime packaging, UN-certified drums, and seamless customs documentation clearance for global transit.

Navigating global chemical compliance requires strict adherence to international safety standards, material hazard classifications, and regional environmental legislation:
Natrium Thioglycolate requires clear classification under GHS (Globally Harmonized System). It is supported with comprehensive 16-section Safety Data Sheets (SDS), EU REACH registration, and certificates of analysis (CoA) per batch to ensure smooth importation through US FDA/EPA, European ECHA, and Asia-Pacific regulatory bodies.
Because Natrium Thioglycolate is susceptible to oxidation upon exposure to air and heavy metals (turning pink due to trace iron contamination), solid products are sealed under inert atmosphere in sealed barrier packaging. Liquid concentrates should be stored in high-density polyethylene (HDPE) drums at 15°C – 25°C away from strong oxidizing agents.
To serve mining centers in Latin America and Africa, localized representative hubs in Mexico and South Africa streamline inventory staging, shorten lead times, handle local customs duties, and provide instant technical support for mine operators and formulation facilities.
