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.
