Calcium thioglycolate is an inorganic compound with the chemical formula C₂H₄O₂S₂Ca. It is a white, crystalline solid that belongs to the class of thioglycolates, characterized by the presence of the thioglycolate anion (C₂H₄O₂S⁻). This compound is primarily used in the cosmetics and personal care industries, particularly in hair treatments.

Calcium thioglycolate functions as a reducing agent, meaning it can donate electrons to other substances. This property makes it useful in chemical hair relaxers, where it helps break disulfide bonds in keratin, the protein that gives hair its structure. By reducing these bonds, the compound allows hair to be straightened or permanently waved. The process involves applying a solution containing calcium thioglycolate, followed by neutralization with an oxidizing agent to restore the bonds in a new configuration.

In addition to its role in hair treatments, calcium thioglycolate has been explored for other applications, though it is less commonly used outside of cosmetics. It is generally considered safe for topical use when applied according to manufacturer guidelines, but like many chemical compounds, it can cause irritation or allergic reactions in sensitive individuals. Proper handling and dilution are essential to minimize risks.

The compound is typically synthesized through a reaction between thioglycolic acid and calcium hydroxide. Its stability and effectiveness in reducing disulfide bonds have made it a staple in the formulation of permanent hair treatments. However, due to concerns about skin sensitivity and potential environmental impact, alternatives are occasionally being researched and developed.
