n-Octyl Thioglycolate is primarily used in the personal care and cosmetics industry as a key ingredient in hair care products. It acts as a reducing agent in permanent hair waving and straightening treatments, helping to break and reform disulfide bonds in keratin to reshape hair fibers. Its effectiveness in these processes makes it a valuable component for achieving long-lasting hairstyles. Additionally, it is utilized in some skincare formulations for its ability to enhance the penetration of active ingredients due to its mild solvent properties. Its application ensures improved product performance while maintaining a balance with skin and hair health.
