Calcium Thioglycolate

INCI Name:
Calcium Thioglycolate

Description:
Calcium Thioglycolate is a white crystalline powder derived as a calcium salt of thioglycolic acid, primarily used in depilatory formulations. It effectively breaks the disulfide bonds in keratin, allowing hair to dissolve and be easily removed. Compared to sulfide-based depilatories, it provides a gentler yet efficient hair removal action with reduced odor and irritation. This ingredient also functions as a keratolytic and mild reducing agent, offering exfoliating and smoothing effects on the skin.
