ISOPROPYL THIOGLYCOLATE

Description

Isopropyl Thioglycolate is a potent chemical compound widely used in professional hair care products, particularly in permanent wave solutions and hair relaxers. This sulfur-containing ester is derived from thioglycolic acid and isopropyl alcohol, giving it unique properties that make it effective in altering hair structure. Its primary function is to break down disulfide bonds in the hair's keratin, allowing for reshaping and restructuring of the hair shaft.

In permanent wave solutions, Isopropyl Thioglycolate penetrates the hair cortex, disrupting the disulfide bonds and enabling the hair to be reshaped into curls or waves. For hair relaxing treatments, it works similarly but aims to straighten naturally curly or kinky hair. The compound's efficiency in bond breaking is typically superior to other thioglycolates, allowing for faster processing times and potentially less damage to the hair.

While effective, Isopropyl Thioglycolate requires careful handling due to its strong odor and potential for skin irritation. Professional application is recommended to ensure proper use and to minimize risks associated with over-processing or skin contact. After treatment, neutralizing agents are used to reform the disulfide bonds in the newly shaped hair configuration.
