Calcium Thioglycolate Trihydrate is a fine crystalline powder of calcium thioglycolate (Mercaptoacetic acid calcium salt) that is used as a depilatory agent.
Calcium thioglycolate is less soluble and also less effective in comparison to potassium thioglycolate. On the other hand the irritancy is much lower.

What Is It?
Thioglycolic Acid is an organic compound that contains a thiol group (-SH) and carboxylic acid. It is a colorless liquid. Thioglycolic Acid and some salts and esters of Thioglycolic Acid, such as Ammonium Thioglycolate, Butyl Thioglycolate, Calcium Thioglycolate, Ethanolamine Thioglycolate, Glyceryl Thioglycolate, Isooctyl Thioglycolate, Isopropyl Thioglycolate, Magnesium Thioglycolate, Methyl Thioglycolate, Potassium Thioglycolate and Sodium Thioglycolate are used in hair coloring products, permanent wave products, hair straightening products and depilatory products.
Why is it used in cosmetics and personal care products?
Thioglycolic Acid and it salts and esters modify hair fibers to facilitate changes to the structure of the fibers, such as with permanent waves or with hair straightening. They are also used to chemically break down hair fibers so that unwanted hair can be removed by simply wiping it from the skin.
Scientific Facts:
Thioglycolic Acid and its salts and esters break disufide bonds in the cortex of the hair. After washing, the hair is treated with a mild solution of hydrogen peroxide, which causes new bonds to form, giving hair the rigid structure necessary for permanent waves.
