Products Description of Carboxymethyl CAS# 79-08-3
Carboxymethyl (glycolic acid) is a colorless, odorless organic compound that serves as a highly versatile hydroxycarboxylic acid. It is soluble in water, ethanol, and other polar solvents, making it ideal for use in personal care, textile processing, oil drilling, and industrial cleaning. It acts as an effective exfoliant, pH regulator, and cleaning agent, and is widely used in skincare formulations, dyeing processes, and metal treatment. It is stable under ordinary conditions but incompatible with strong bases and oxidizing agents.
