Octadecyl thioglycolate is widely used in the polymer industry as a stabilizer and modifier. It helps in enhancing the thermal stability of polymers, making them more resistant to degradation under high temperatures. This chemical is also employed in the production of lubricants, where it acts as an additive to improve the performance and longevity of the lubricant by reducing friction and wear. Additionally, it finds application in the cosmetic industry, where it is used in formulations to improve the texture and stability of products like creams and lotions. Its ability to act as a surfactant makes it useful in various industrial cleaning agents, aiding in the effective removal of oils and greases.
