Used as a non-ionic surfactant in personal care products such as shampoos, conditioners, and body washes due to its excellent emulsifying and foaming properties. It enhances foam stability and provides mildness to the formulations, making it suitable for sensitive skin products. Also functions as a corrosion inhibitor in metalworking fluids and provides lubricity in textile processing. Its biodegradability and low toxicity support use in environmentally friendly formulations.
