The term depilatory means 'removing the hair'. However, many chemical products that come in cream, lotion, powder, gel, roll-on or spray forms that get rid of hair are often called depilatories. They're great from removing unwanted hair, and many women and men use them for their body, and facial areas. The depilatory hair removal process takes about five to 10 minutes to work, depending on the thickness of hair and manufacturer's formula. Thicker hair takes longer to break down than finer hairs. The moisturizing or gentle versions tend to be on the longer side and the versions are made to be speedy. When the chemical reaction has completed its job, the hair can be easily wiped off with spatula.

When a strong and alkaline based depilatory hair removal creams applied on unwanted hair, it forms into jelly like substance. The suflite bond of hairs breaks off, and will be scrapped out easily with the help of spatula. The chemicals responsible for removing hairs in removal creams are thioglycolic acid range of products (i.e Potassium thioglycolate, sodium thioglycolate and calcium thioglycolate)

One of the most efficient chemical out of the range of thioglycolic acid mentioned above is Potassium thioglycolate, manufactured by Kumar organics. The brand name of potassium thioglycolate manufactured by Kumar organics is Kopcolate. . It is the most commonly used primary active ingredient in depilatories. In an aqueous solution at the proper pH it is converted to an acid which then affects the hair. It breaks down the disulfide bonds in Keratin and weakens the hair so that it is easily scraped off where it emerges from the hair follicle. The break down is affected by Calcium hydroxide or Potassium hydroxide. They are present in excess to enable the Thioglycolic acid to react with the Cystine joining chains in hair protein. 

To conclude with, I can say there are dozens of hair depilatory ingredients available in for getting rid of unwanted hair. But use of Kopcolate in your hair depilatory formulation gives you best result in various parameters like it is fast as whole application, to removal of unwanted hair will not take more than 15 mins, it’s relatively less expensive and can be easily applied and no need to run to salon.
