Calcium Thioglycolate (CAS 814-71-1) is the calcium salt of thioglycolic acid, a white to off-white solid supplied in 98% purity or as a trihydrate, and it works as a reducing agent that breaks disulfide bonds in keratin for depilatory creams and leather dehairing. It is typically supplied in 98% Purity or as a trihydrate form to ensure maximum stability and reactivity in alkaline formulations.
This Cosmetic Grade salt offers excellent solubility and is preferred over sodium variants in specific depilatory applications due to its controlled reaction rate. Its reductive properties make it essential for achieving smooth results in professional and consumer personal care products.
As a Technical Grade intermediate, it also serves the leather industry for hair removal from hides. The compound is valued for its consistent quality and its role as a key active ingredient in pH-adjusted chemical depilatories.
