Thioglycolic acid(TGA) , also known as mercaptoacetic acid (CAS 68-11-1), is a high-value chemical intermediate with strong reducing and chelating properties. Its unique structure—combining a thiol group (-SH) and a carboxylic acid group (-COOH)—makes it indispensable across multiple industries, from cosmetics to PVC manufacturing.

If you are sourcing TGA for production, understanding its applications, quality requirements, and supplier selection criteria is essential.

Key Applications

Industry Application

Cosmetics & Personal Care Hair waving solutions, straighteners, depilatory creams

PVC Manufacturing Production of heat stabilizers (organotin) for pipes, window frames, medical devices

Mining Collector agent in froth flotation for ore processing

Water Treatment Oxygen scavenger, corrosion inhibitor in boiler systems

Chemical Synthesis Building block for thiolactic acid, esters, and pharmaceutical intermediates

 How to Choose a Reliable Supplier

When evaluating TGA suppliers, consider these critical factors:

 Purity & Grade

Industrial grade: 99% purity is standard for most applications

Cosmetic grade: Requires additional certifications (EU, FDA compliance)

Documentation

A trustworthy supplier provides:

COA (Certificate of Analysis) per batch

TDS (Technical Data Sheet)

MSDS (Material Safety Data Sheet)

 Packaging Options

25kg or 250kg plastic drums

IBC tanks (1,000kg)

ISO tanks for bulk international shipments

Certifications

Look for ISO 9001, REACH, or FDA certifications depending on your target market.

Safety & Handling

Thioglycolic acid is classified as a corrosive substance (Class 8) . Proper safety measures are essential:

Aspect Requirement

Storage Cool, well-ventilated area; away from oxidizing agents

PPE Chemical-resistant gloves, goggles, protective clothing

Spill Neutralize with sodium bicarbonate; dispose per local regulations

Shipping UN 1940 — requires hazardous material documentation

Why Quality Matters

Impurities in TGA can affect downstream reactions, leading to:

Inconsistent performance in PVC stabilizers

Color instability in cosmetic formulations

Reduced effectiveness in mining and water treatment

Working with an established manufacturer ensures batch-to-batch consistency and reliable supply chains.

Conclusion

Thioglycolic acid is a critical raw material with diverse industrial applications. Whether you need high-purity TGA for cosmetic formulations or bulk quantities for PVC stabilizer production, selecting the right supplier is key to operational success.
