What is the main ingredient in chemical depilatories?

Explanation:
Chemical depilatories rely on a thioglycolate derivative as the active ingredient. This compound penetrates the hair and breaks the keratin disulfide bonds that give hair its strength, weakening the hair so it can be dissolved or wiped away during removal. That bond-breaking action is what makes the product effective at hair removal. Urea functions mainly as a moisturizer and helps soften skin or keratin in some products, but it doesn’t dissolve hair by breaking keratin bonds. Salicylic acid is a keratolytic used for exfoliation and acne care, not for breaking hair’s keratin structure. Alcohol acts as a solvent and helps with drying and disinfection, not with weakening and removing hair.
