Ammonium Thioglycolate (also known as Ammonium Thioethanolate) is a highly efficient reducing thiol compound. Its core function is to cleave the disulfide bonds in keratin, making it a key raw material for cold wave perms, hair straightening, and depilatories.
Product Advantages
  • 1 Strong Reducing Power: Precision cleavage of disulfide bonds in hair keratin.
  • 2 Neutral & Mild: pH (6.0–6.8) is close to human skin, minimizing damage.
  • 3 Water Solubility: Excellent compatibility for various aqueous formulations.
  • 4 Flexible Application: Easily adjustable action intensity via concentration.
  • 5 Multifunctionality: Serves as a corrosion inhibitor and chemical reagent.
Application Areas
1 Hair Care Industry
  • Cold Wave Solutions: Core agent for permanent curling.
  • Straightening Creams: Works with neutralizers for permanent straightening.
  • Depilatory Products: Softens keratin for easy body hair removal.
Recommended Concentration: 5%–15% for perming; 2%–8% for depilatory use.
2 Industrial Fields
  • Metal Corrosion Inhibition: Forms protective FeS film (140–200℃).
  • Chemical Analysis: Masking and reducing agent for ion determination.
  • Electronic Cleaning: Metal surface treatment auxiliary agent.

Frequently Asked Questions
Q What are the primary uses of Ammonium Thioglycolate?
It is mainly used as a reducing agent in hair cosmetics for permanent waving, straightening, and as a key component in gentle depilatory formulations.
Q Which concentrations are available for purchase?
We provide standard industrial concentrations of 50%, 60%, and 70% to meet various formulation needs.
Q Is it safer than traditional thioglycolic acid?
Yes, with a pH of 6.0–6.8, it is significantly milder and closer to the natural pH of skin, leading to reduced irritation and hair damage.
Q Can it be used in industrial metal treatment?
Absolutely. It acts as an effective corrosion inhibitor for carbon steel in high-temperature brine environments (up to 200℃).
Q What is the best way to store this chemical?
It should be kept in a cool, dark place, preferably refrigerated at 2–8℃, and kept away from iron or copper to prevent degradation.
Q What is the recommended dosage for hair products?
Typically, 5%–15% is used for perming/straightening solutions, while 2%–8% is used for depilatory creams.
