What is Calcium thioglycolate?
Calcium thioglycolate (CAS 814-71-1), also marketed as Ebacream and Depil, is the calcium salt of thioglycolic acid used as a depilatory active in personal care formulations.
Where is Calcium thioglycolate used?
- Depilatory creams and lotions: functional ingredient that dissolves hair at the skin surface
- Professional salon and at-home hair removal formats, including rinse-off creams and gel systems for legs, underarms and facial areas
- Keratin-modifying treatments requiring controlled bond disruption
- It breaks down the disulfide bonds in keratin, enabling hair removal without mechanical action.
Good to know: Selected over ammonium thioglycolate where a milder odor profile and lower alkalinity are preferred for sensitive skin products. Cosmetic-grade material meets purity requirements relevant to finished personal care applications.
