Sodium sarcosinate is widely used in the personal care and cosmetic industry as a surfactant and foam booster. It is commonly found in shampoos, body washes, and facial cleansers due to its ability to create a rich lather while being gentle on the skin and hair. Its mild cleansing properties make it suitable for sensitive skin formulations.

In the pharmaceutical industry, it serves as an excipient in drug formulations, enhancing the solubility and stability of active ingredients. It is also used in oral care products like toothpaste and mouthwash for its foaming and cleaning effects.

Additionally, sodium sarcosinate is employed in industrial applications as a corrosion inhibitor, particularly in metalworking fluids, to protect metal surfaces from rust and degradation. Its versatility and effectiveness across various industries make it a valuable chemical compound.
