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. It is also utilized in fields such as metal corrosion inhibition and chemical analysis.
Product Advantages
  • 1
    Strong Reducing Power & Precision: Selectively cleaves disulfide bonds in hair keratin, delivering significant softening and reshaping effects.
  • 2
    Neutral & Mild: With a pH close to that of human skin and hair, it is less irritating than traditional thioglycolic acid and causes minimal damage to hair quality.
  • 3
    Excellent Water Solubility: Easy to formulate into various aqueous solutions and creams, offering good compatibility with different formulations.
  • 4
    Flexible Application: Action intensity can be adjusted via concentration and pH, making it suitable for diverse scenarios such as perming, hair straightening, and depilatory uses.
  • 5
    Multifunctionality: Beyond hair care, it serves as a metal corrosion inhibitor, chemical analysis reagent, and thiolating agent.
Application Areas
1 Hair Care Industry (Core Application)
  • Cold Wave Lotions / Perm Solutions: Softens hair keratin and reshapes disulfide bonds to achieve permanent curling; serves as the core reducing agent in cold perms.
  • Hair Straightening Creams / Relaxers: Cleaves disulfide bonds to soften hair, working in conjunction with neutralizers to achieve permanent straightening.
  • Depilatory Creams / Lotions: Softens body hair keratin to facilitate easy removal; the preferred choice for mild depilatory products.
  • Recommended Concentration: 5%–15% for perming/straightening; 2%–8% for depilatory use.
2 Industrial & Other Fields
  • Metal Corrosion Inhibition: Forms a protective FeS film in high-temperature brine/completion fluids to inhibit carbon steel corrosion (140–200℃).
  • Chemical Analysis: Used as a masking agent and reducing agent for the photometric determination of ions such as iron, aluminum, silver, and tin.
  • Material Modification: Serves as a thiolating agent for the preparation of adsorption materials and functional polymers.
  • Electronic Cleaning: Acts as an auxiliary agent for metal surface treatment and cleaning.

? Frequently Asked Questions
Q1 What is Ammonium Thioglycolate and what is its main function?
Ammonium Thioglycolate (also known as Ammonium Thioethanolate) is a highly efficient reducing thiol compound. Its primary function is to selectively cleave disulfide bonds in hair keratin, which allows it to soften and reshape hair structures. This makes it the key active ingredient in cold wave perms, hair straightening products, and depilatory creams.
Q2 What concentrations of Ammonium Thioglycolate are available, and which should I choose?
Ammonium Thioglycolate is available in three standard purity grades: 50%, 60%, and 70%. For perming and hair straightening applications, a working concentration of 5%–15% is recommended. For depilatory products, 2%–8% is typically sufficient. The appropriate grade and dilution depend on your specific formulation requirements.
Q3 Is Ammonium Thioglycolate safe for use in cosmetic and hair care formulations?
Yes. Ammonium Thioglycolate has a pH range of 6.0–6.8, which is close to the natural pH of human skin and hair. This makes it milder and less irritating compared to traditional thioglycolic acid. When used at recommended concentrations and in properly formulated products, it causes minimal damage to hair quality and is well-tolerated by most users.
Q4 Can Ammonium Thioglycolate be used in industrial applications beyond hair care?
Absolutely. Beyond its core use in hair care, Ammonium Thioglycolate is widely used in industrial and technical fields. It acts as a metal corrosion inhibitor by forming a protective FeS film on carbon steel surfaces in high-temperature brine and completion fluids (140–200℃). It is also used as a chemical analysis reagent, a thiolating agent for material modification, and an auxiliary agent in electronic metal surface cleaning.
Q5 What are the storage requirements for Ammonium Thioglycolate?
Ammonium Thioglycolate should be stored in a cool, dry, and dark environment. Refrigerated storage at 2–8℃ is preferred to maintain product stability. It is important to avoid contact with iron or copper, as these metals can catalyze degradation and affect product quality.
Q6 What packaging options are available for Ammonium Thioglycolate?
Ammonium Thioglycolate is available in two standard packaging sizes: 25 kg drums for smaller or laboratory-scale orders, and 200 kg drums for bulk industrial or commercial procurement. Custom packaging arrangements may be available upon request depending on order volume.
