Description

Calcium Thioglycolate is an inorganic salt of thioglycolic acid, widely recognized for its role as a key reducing agent and depilatory compound. Its commercial importance stems from its ability to effectively break disulfide bonds in keratin, a property leveraged across several high-value industries. This makes it an essential raw material for manufacturers in the personal care, pharmaceutical, and chemical synthesis sectors seeking reliable and consistent quality.

Application

• Cosmetic Depilatories: Primary active ingredient in cream, gel, and lotion hair removal products for its efficient breaking of hair keratin bonds.
• Pharmaceutical Intermediates: Used in the synthesis of certain active pharmaceutical ingredients (APIs) where a thiol or disulfide modification is required.
• Chemical Synthesis: Serves as a versatile reducing agent and a source of the thioglycolate anion in organic and inorganic synthesis processes.
• Hair Care Products: Employed in specific permanent wave (perm) solutions and hair straightening formulations to alter hair structure.
• Laboratory Reagent: Utilized in biochemical and analytical research for protein analysis and as a reducing agent in various test protocols.
• Leather Processing: Acts in some depilatory formulations for the leather tanning industry to remove hair from hides.
