Used as a hydrotrope to improve the solubility of poorly soluble compounds in aqueous solutions, particularly in liquid cleaning products such as shampoos, body washes, and household detergents. It helps stabilize formulations by preventing cloudiness and phase separation. Also functions as a viscosity modifier, aiding in the control of product thickness without affecting performance. Commonly found in consumer personal care products due to its low irritation potential and good compatibility with surfactants and fragrances.
